Requirements~
                                                          *vimtex-requirements*

  `latexmk`  http://users.phys.psu.edu/~collins/software/latexmk-jcc
    |vimtex| uses `latexmk` to compile the LaTeX document.  `latexmk` is "a perl
    script for running LaTeX the correct number of times to resolve cross
    references, etc; it also runs auxiliary programs (bibtex, makeindex if
    necessary, and dvips and/or a previewer as requested).  It has a number of
    other useful capabilities, for example to start a previewer and then run
    latex whenever the source files are updated, so that the previewer gives
    an up-to-date view of the document. The script runs on both UNIX and
    MS-WINDOWS (XP, etc)." [Copied from the latexmk page.]  For more info, see
    |vimtex-latexmk|.

  |clientserver|
    |vimtex| requires the |clientserver| for the callback functionality to
    work.  The callbacks are used to provide feedback when compilation is
    finished, as well as to parse the log for errors and warnings and to open
    the |quickfix| window when necessary.

    If you use Vim under a terminal in Linux or OSX, then Vim must be
    started as a command server with the command line option `--servername`,
    e.g. `vim --servername VIM`.  For different ways of ensuring this, see:
    http://vim.wikia.com/wiki/Enable_servername_capability_in_vim/xterm

------------------------------------------------------------------------------
Support for multi-file projects~
                                                            *vimtex-multi-file*

|vimtex| supports most multi-file documents.  The main method uses a recursive
search algorithm that should find the main LaTeX file in most cases.  For
special cases, there are several alternative methods for specifying the main
file.  These alternative methods all require some explicit declaration of the
main file.  Thus, these methods will be tried first, and the recursive search
is tried last if there are no explicit declarations that yield an appropriate
main LaTeX file candidate.

The methods are tried in the following order:

  1. Buffer variable
  2. TeX root specifier
  3. Subfiles package
  4. File `.latexmain` specifier
  5. Recursive search

                                                                 *b:vimtex_main*
Buffer variable~
  The main file may be specified through the buffer variable `b:vimtex_main`.
  If one uses project specific |vimrc| files, one may then use an |autocmd| to
  specify the main file through this buffer variable with >

    autocmd FileType tex let b:vimtex_main = 'main.tex'

TeX root specifier~
  It is also possible to specify the main TeX file with a comment in one of
  the first five lines of the current file similar to this: >

    %! TEX root = /path/to/my-main.tex
<
                                                               *vimtex-subfiles*
                                                                 *vimtex-import*
Subfiles package~
  |vimtex| also supports the `import` and the `subfiles` packages that can be used to
  make it easier to work with multi-file projects. If one uses the `subfiles`
  package, the |VimtexToggleMain| command is particularly useful.

    - https://www.ctan.org/pkg/import
    - https://www.ctan.org/pkg/subfiles

File .latexmain specifier~
  In some cases, it might be preferable to specify the main file by creating
  an indicator file.  The indicator file should be an empty file, and the name
  must be the name of the desired main file with `.latexmain` appended.  An
  example should make this clear: >

    path/file.tex
    path/file.tex.latexmain
    path/sections/file1.tex
    path/sections/file2.tex
<
  Here `path/file.tex.latexmain` indicates for `file1.tex` and `file2.tex`
  that `path/file.tex` is the main LaTeX file.

Recursive search~
  If no other method provides an appropriate candidate, then the recursive
  search detects the main LaTeX file by searching for a file in the current
  and parent directories that includes the present file and that has the
  `\documentclass` line.

  This should work in most cases, but it may fail if for instance the project
  structure is something like this: >

    path1/main.tex
    path2/chapter.tex
<
  That is, the main file detection will not work for the file `chapter.tex`,
  because the main file does not live in the same folder or a parent folder.
  In this particular case, the TeX root specifier should work.

------------------------------------------------------------------------------
Comment on internal tex plugin~
                                                      *vimtex-comment-internal*

Vim ships with some LaTeX support out of the box.  In particular, it provides
good syntax highlighting (|ft-tex-syntax|), indentation (see the source file
$VIMRUNTIME/indent/tex.vim for the documentation), and some sensible options
(|ft-tex-plugin|).

When |vimtex| is active, it will be used as the main |ftplugin|.  It will
define the same set of sensible settings as the internal plugin.  However,
|vimtex| does not provide its own syntax, instead it adds a few minor
improvements to |ft-tex-syntax|, see |vimtex-syntax|.  |vimtex| also provides its
own indentation plugin, see |vimtex-indent|.

Vim will generally autodetect filetypes automatically.  In most cases this
works as expected, however, in some cases it will detect a file with the `tex`
suffix as a |plaintex|.  To prevent this, one may set the option
|g:tex_flavor| in ones `vimrc` file, that is: >

  let g:tex_flavor = 'latex'

==============================================================================
USAGE                                                            *vimtex-usage*

  Default mappings        |vimtex-default-mappings|
  Options                 |vimtex-options|
  Commands                |vimtex-commands|
  Map definitions         |vimtex-mappings|
  Insert mode mappings    |vimtex-imaps|
  Events                  |vimtex-events|

------------------------------------------------------------------------------
Default mappings~
                                                      *vimtex-default-mappings*

|vimtex| is designed to be controlled by a selection of mappings.  Note,
though, that most of the mappings are also available as commands, see
|vimtex-commands|.

Many of the mappings utilize the |maplocalleader|. The right-hand sides are
provided as <plug>-mappings, see |using-<plug>|. For any given <plug> map, the
default mapping will only be created if it does not already exist. This means
that if a user defines a custom mapping, e.g. with >

  nmap <space>li <plug>(vimtex-info)

then the corresponding default left-hand side will not be mapped.

If one prefers, one may disable all the default mappings through the option
|g:vimtex_mappings_enabled|.  One must then define custom mappings for all
desired features through the listed RHS <plug>-maps or by mapping the
available commands.

In the below list of mappings, LHS is the default mapping, RHS is the
corresponding <plug>-maps, and MODE indicates in which vim mode the mappings
are valid.

In addition to the mappings listed below, |vimtex| provides convenient insert
mode mappings to make it easier and faster to type mathematical equations.
This feature is explained in more detail later, see |vimtex-imaps|.

Options~
                                                               *vimtex-options*

*g:vimtex_enabled*
  Set to 0 to disable |vimtex|.

  Default value: Undefined.

*g:vimtex_disable_version_warning*
  |vimtex| will warn you if you are using an unsupported version of Vim. This
  warning may be disabled by setting this option to a nonzero value.

  Default value: Undefined.

*g:vimtex_complete_enabled*
  Use this option to disable/enable |vimtex| completion.

  Default value: 1

*g:vimtex_complete_close_braces*
  This option controls whether to append a closing brace after a label or
  a citation has been completed.

  Default value: 0

*g:vimtex_complete_recursive_bib*
  This option toggles recursive searching for bibliography files.

  Note: This feature may lead to a significant lag for large projects.

  Default value: 0

*g:vimtex_complete_img_use_tail*
  If enabled, only the tail part of file names are completed.  This is useful
  if one uses the `graphicx` package and the `\graphicspath` command.

  Default value: 0

*g:vimtex_delim_toggle_mod_list*
  Define list of delimiter modifiers to toggle through with
  |<plug>(vimtex-delim-toggle-modifier)|.

  For example, to toggle between no modifiers, the `\left/\right` pair, and
  the `\bigl/\bigr` pair, use: >

    let g:vimtex_delim_toggle_mod_list = [
      \ ['\left', '\right']
      \ ['\bigl', '\bigr']
      \]
<
  Default value: [['\left', '\right']]

*g:vimtex_delim_stopline*
  A tolerance for the number of lines to search for matching delimiters in
  each direction. It is used in an expression for the {stopline} argument of
  |search()| function calls. If the option is increased it will make the
  matching more accurate, at the expense of potential lags. The default value
  should work well for most people.

  Default value: 500

*g:vimtex_format_enabled*
  If enabled, |vimtex| uses a custom |formatexpr| that should handle inline
  comments. That is, if it is enabled, then comments at end of lines will not
  be joined with the |gq| command.

  Default value: 0

*g:vimtex_fold_enabled*
  Use this option to enable folding. More detailed info can be found in the
  section |vimtex-folding|.

  Default value: 0

*g:vimtex_fold_manual*
  With this option enabled, |vimtex| uses |fold-manual| as the main
  |foldmethod|.  It still uses the |foldexpr| function to compute the fold
  levels, but it only computes the fold levels on demand, see
  |VimtexRefreshFolds| and |vimtex-zx|.

  The reasoning behind this option is that the |fold-expr| method of folding
  may sometimes be slow, e.g. for long lines and large files. |fold-manual| is
  very fast.

  An alternative to this method of speeding up is to use a dedicated plugin
  for optimizing the fold functionality, see e.g.
  https://github.com/Konfekt/FastFold.

  Default value: 0

*g:vimtex_fold_comments*
  Control whether or not to fold multiline comments.

  Default value: 0

*g:vimtex_fold_levelmarker*

  Use custom section symbol for folding.

  Default value: '*'

*g:vimtex_fold_envs*
  Control whether or not to fold environments.

  Default value: 1

*g:vimtex_fold_parts*
  List of document parts that should be folded.

  Default value: >
    let g:vimtex_fold_parts = [
        \ "appendix",
        \ "frontmatter",
        \ "mainmatter",
        \ "backmatter",
      \ ]
<
*g:vimtex_fold_preamble*
  Control whether or not to fold the preamble.

  Note: This option can not be used together with |g:vimtex_fold_documentclass|.

  Default value: 1

*g:vimtex_fold_sections*
  List of section constructs that should be folded.

  Default value: >
    let g:vimtex_fold_sections = [
        \ "part",
        \ "chapter",
        \ "section",
        \ "subsection",
        \ "subsubsection",
      \ ]
<
*g:vimtex_fold_usepackage*
  Use this option to disable/enable folding of long `\usepackage` lines. The
  lines must be formatted like this for folding to work properly: >

    \usepackage[
      option 1,
      ...,
      option n
      ]{name}
<
  Default value: 1

*g:vimtex_fold_documentclass*
  Use this option to disable/enable folding of long `\documentclass` lines. This
  works similar to |g:vimtex_fold_usepackage|.

  Note: This option can not be used together with |g:vimtex_fold_preamble|.

  Default value: 0

*g:vimtex_imaps_enabled*
  Use this option to disable/enable the insert mode mappings.

  Default value: 1

*g:vimtex_imaps_leader*
  The default leader key for insert mode mappings.

  Default value: '`'

*g:vimtex_imaps_disabled*
  A list of mappings to disable. That is, any left-hand side that matches
  a string in this list will not be mapped to its corresponding right-hand
  side. This may be used to selectively disable one or more from the default
  list of mappings.

  Default value: []

*g:vimtex_imaps_list*
  The list of mappings to generate on start up. The list of activated mappings
  can be viewed with |VimtexImapsList|.

  Default value: Complicated, please see the source file for exact value:
                 `autoload/vimtex/imaps.vim`

*g:vimtex_indent_enabled*
  Use this option to disable/enable |vimtex| indentation.

  Default value: 1

*g:vimtex_indent_bib_enabled*
  Use this option to disable/enable |vimtex| indentation of bibliography files.

  Default value: 1

*g:vimtex_index_hide_line_numbers*
  If enabled, then line numbers will be hidden in the index windows.  That is,
  |nonumber| and |norelativenumber| will be set locally.

  Default value: 1

*g:vimtex_index_resize*
  Whether or not to automatically resize vim when index windows are opened.

  Note: This option makes sense if the index window is vertically split.

  Default value: 0

*g:vimtex_index_show_help*
  Whether to display the index help text.

  Default value: 1

*g:vimtex_index_split_pos*
  Define where index windows should be opened. This is a string that contains
  either the word 'full' to open in the current window, or any of the position
  commands, i.e. one or more of |:vertical|, |:leftabove|, |:rightbelow|, |:topleft|,
  and |:botright|.

  Default value: 'vert leftabove'

*g:vimtex_index_split_width*
  For vertically split windows: Set width of index window.

  Default value: 30

*g:vimtex_labels_enabled*
  Use this option to disable/enable table of labels.

  Default value: 1

*g:vimtex_toc_enabled*
  Use this option to disable/enable table of contents (ToC).

  Default value: 1

*g:vimtex_toc_fold*
  Turn on folding of ToC entries.

  Default value: 0

*g:vimtex_toc_fold_levels*
  This option controls the number of fold levels that will be used if the
  folding of the ToC is enabled.

  Default value: 1

*g:vimtex_toc_show_preamble*
  Whether to include the preamble in the ToC.

  Default value: 1

*g:vimtex_toc_show_numbers*
  Set whether or not to show section numbers in ToC.

  Note: The numbers may also be toggled inside the ToC window with the `s`
        keybinding.

  Default value: 1

*g:vimtex_toc_number_width*
  Set the display width of numbers in the ToC.  If it is set to 0, then the
  width is set based on the section depth, see |g:vimtex_toc_secnumdepth|.

  Default value: 0

*g:vimtex_toc_secnumdepth*
  Define the number of section levels to display.  Set level corresponding to
  the desired latex variable `secnumdepth`.  For more info on `secnumdepth`,
  see http://en.wikibooks.org/w/index.php?title=LaTeX/Document_Structure.

  Note: The variable may be updated inside the ToC window with the mappings
        `+` and `-`.

  Default value: 3

*g:vimtex_mappings_enabled*
  Control whether or not to load the default mappings.

  Default value: 1

*g:vimtex_motion_enabled*
  This option enables the motion mappings `%`, `[[`, `[]`, `][`, and `]]`. It
  also enables the highlighting of matching delimiters.

  Default value: 1

*g:vimtex_motion_matchparen*
  Enable highlighting of matching delimiters.

  Note: This is an improved version of |matchparen|. It should be possible to
        keep |matchparen| activated, which matches delimiters listed in
        'matchpairs'. The |vimtex| specific version will also match LaTeX
        specific delimiters, which is not possible with |matchparen|.

  Default value: 1

*g:vimtex_latexmk_enabled*
  Use this option to disable/enable the `latexmk` interface |vimtex-latexmk|.

  Default value: 1

*g:vimtex_latexmk_build_dir*
  This option sets the compilation build directory.  It corresponds to the
  `-output-directory` option in `latexmk`.  If the path is a relative path,
  then it will be considered relative to the main project file.

  Note that this option only works with `latexmk` version 4.27 and later.

  Default value: ''

*g:vimtex_latexmk_callback*
  If enabled, this option tells `latexmk` to run |vimtex#latexmk#callback| after
  compilation is finished.

  Note 1: This feature requires |clientserver|.
  Note 2: Callbacks are only possible when continuous mode is active, see
          |g:vimtex_latexmk_continuous|.
  Note 3: The callback is run with the vim executable defined by
          |g:vimtex_latexmk_progname|.

  Default value: 1

*g:vimtex_latexmk_callback_hooks*
  A list of functions that will be called from the vimtex latexmk callback.
  The compilation status must be taken as an argument. This allows users to
  add custom callback functionality.

  Note: The Zathura and MuPDF viewers, if used, adds a hook to this list in
        order to store the viewer X window ID in order to prevent multiple
        viewer windows.

  Example: >

    let g:vimtex_latexmk_callback_hooks = ['MyTestHook']

    function! MyTestHook(status)
      echom a:status
    endfunction

<  Default value: []

*g:vimtex_latexmk_continuous*
  If enabled, `latexmk` will run in continuous mode, i.e. with the `-pvc`
  argument.  This means that the document is compiled every time a document
  file has been changed.

  If disabled, `latexmk` will run single shot compilations.

  Default value: 1

*g:vimtex_latexmk_background*
  If continuous mode is disabled, then this option may be used to set
  whether single shot compilations should be run in the foreground or the
  background.

  Default value: 0

*g:vimtex_latexmk_options*
  By default, |vimtex| passes the following options to `latexmk`: >

     -pdf                     -- Compile to pdf documents
     -verbose                 -- More verbose output
     -file-line-error         -- Enable file:line:error style messages
     -synctex=1               -- Generate synctex data
     -interaction=nonstopmode -- Disable interactive mode

<  However, if `g:vimtex_latexmk_options` is defined and is nonzero, it will
  override the above with the user supplied options.

  Note: Options may also be specified indirectly to `latexmk` through
        both a global and a project specific `.latexmkrc` file. One should
        know, though, that options specified on the command line has priority,
        and so if one wants to override one of the above default options, then
        one has to set `g:vimtex_latexmk_options` to a string that contains
        the desired options.

  Default value: ''

*g:vimtex_latexmk_progname*
  Path to vim executable.  This is used for the callback functionality, and it
  must be set correctly in order for the callback function to work.  The
  default value should work correctly in most cases, but in some cases, e.g.
  for MacVim, one might need to set it manually to get the callbacks to work
  as expected.

  Default value: |v:progpath| if it exists, else |v:progname|.

*g:vimtex_quickfix_autojump*
  This option controls if vim should automatically jump to the first error
  whenever the |quickfix| window is opened.

  Note: This option does not go well with continuous compilation and
        callbacks, since the callbacks will open the quickfix window if there
        are errors.  Thus I recommend to keep it disabled for continuous
        compilation, and rather enable it if one prefers single shot
        compilations.

  Default value: 0

*g:vimtex_quickfix_ignore_all_warnings*
  This option controls whether or not LaTeX warnings should be included in the
  |quickfix| window.  LaTeX errors will always be included.

  Default value: 0

*g:vimtex_quickfix_ignored_warnings*
  A list of warning messages that should be ignored.  The list is a list of
  strings.  Any LaTeX warning that contains a string in the list will be
  ignored.

  To ignore some common LaTeX warnings, try the following setting: >
    let g:vimtex_quickfix_ignored_warnings = [
        \ 'Underfull',
        \ 'Overfull',
        \ 'specifier changed to',
      \ ]
<
  Note: This option is only relevant if |g:vimtex_quickfix_ignore_all_warnings|
        is disabled.

  Default value: []

*g:vimtex_quickfix_mode*
  This option controls the behaviour of the |quickfix| window in case errors
  and/or warnings are found.  The recognized options are:

  Value  Effect ~
  0      The quickfix window is never opened automatically.
  1      The quickfix window is opened automatically when there are errors,
         and it becomes the active window.
  2      The quickfix window is opened automatically when there are errors,
         but it does not become the active window.

  Note: The quickfix window will only be opened automatically if both the
        continuous mode and the callbacks are active, see
        |g:vimtex_latexmk_continuous| and |g:vimtex_latexmk_callback|.

  Default value: 2

*g:vimtex_quickfix_open_on_warning*
  Control whether or not to automatically open the |quickfix| window in case
  there are warning messages and no error messages.

  Note: The quickfix window will only be opened automatically if both the
        continuous mode and the callbacks are active, see
        |g:vimtex_latexmk_continuous| and |g:vimtex_latexmk_callback|.

  Default value: 1

*g:vimtex_text_obj_enabled*
  Use this option to disable the text object mappings.

  Default value: 1

*g:vimtex_text_obj_linewise_operators*
  List of operators that will act linewise on the delimiter text objects (i.e.
  `ie/ae`, `i$/a$`, and `id/ad`). Note, for inline regions the operators will not
  act linewise, since that would lead to side effects.

  Default value: ['d', 'y']

*g:vimtex_view_enabled*
  Use this option to disable/enable the |vimtex| viewer interface.

  Default value: 1

*g:vimtex_view_use_temp_files*
  If enabled, this will copy output files to a corresponding set of files
  with `_vimtex` prepended to the name. If one combines this with the callback
  feature, this may provide a very convenient way to avoid that the pdf
  becomes unavailable during compilation, as it will only update the viewer
  outut file after a successful compilation.

  Note: This will disable the viewer from the latexmk end. That is, if this
        option is enabled, opening and updating the pdf viewer will have to be
        done by the user or by vimtex.

  Note: This works best with the 'mupdf' and 'zathura' viewers. In particular,
        these viewers should update automatically after the pdf is updated.
        For general viewers, one has to create a callback function and connect
        it through |g:vimtex_view_general_callback|, and then use this
        callback to update the viewer.

  Default value: 0

*g:vimtex_view_method*
  Set the viewer method.  The general viewer |vimtex_viewer_general| defines
  a generic interface that allows sufficient customization for most viewer
  applications.  However, a few applications require some special attention,
  and so |vimtex| provides a couple of custom viewers: |vimtex_viewer_mupdf| and
  |vimtex_viewer_zathura|.

  Possible values:
    'general' (default)
    'mupdf'
    'zathura'

    *vimtex_viewer_general*
      This is a generic interface where the viewer application is specified
      through |g:vimtex_view_general_viewer| and the viewer options are given
      with |g:vimtex_view_general_options|.  After successful compilation with
      `latexmk`, the viewer is started with the options provided by
      |g:vimtex_view_general_options_latexmk|.  The interface allows the
      general viewer to support forward search with a lot of different
      applications:

    *vimtex_viewer_mupdf*
      http://www.mupdf.com/
      A very minimalistic and quick PDF viewer.  Supports forward and backward
      search.  Backward search is available with |VimtexRSearch|, which is
      mapped to '<localleader>lr'.  One may also define a set of keys that is
      sent to MuPDF on startup with |g:vimtex_view_mupdf_send_keys|.

      Note: Both forward and backward search requires `xdotool` to work.
            Forward search will only take you to the correct page.  Backward
            search will take you to the line in Vim that corresponds to the
            first line of the current page in MuPDF.

    *vimtex_viewer_zathura*
      https://pwmt.org/projects/zathura/
      Zathura is like MuPDF a very fast and minimalistic viewer, but it allows
      more user configuration.  Zathura supports forward search and backward
      search.

      Note: Forward search requires `xdotool` to work properly, in order to
            not open a new Zathura instance for invocation of |VimtexView|.

      Note: Recent versions of Zathura no longer ensures synctex support. This
            has resulted in synctex support being dropped on some platforms,
            e.g. on OpenSUSE, cf. https://github.com/lervag/vimtex/issues/384.
            A workaround is to build Zathura from source manually.

*g:vimtex_view_general_viewer*
  Use generic viewer application, see |vimtex_viewer_general|.

  Default value:
    Linux: `xdg-open`
    Mac:   `open`

*g:vimtex_view_general_options*
  Set options for the specified general viewer, see |vimtex_viewer_general|.
  The options are parsed to substitute the following keywords:

    `@pdf`    Path to pdf file
    `@tex`    Path to tex file
    `@line`   Current line number
    `@col`    Current column number

  Default value: '@pdf'

*g:vimtex_view_general_callback*
  Sets the name of a function that is called within |vimtex#latexmk#callback|
  after compilation has finished. The function does not take any arguments,
  instead it can use the `b:vimtex` variable directly, e.g. the pdf file is
  available as `b:vimtex.out()`. The function is part of the viewer
  dictionary, and as such it may be defined with the |func-dict| argument. See
  the source for the reference of the viewer dictionary.

  Default value: ''

*g:vimtex_view_general_options_latexmk*
  Set options that are passed on to `latexmk` for the specified general
  viewer, see |vimtex_viewer_general|.  This allows to send options that
  ensures a unique viewer, e.g. with |vimtex_viewer_qpdfview|. Only the
  `@line` escape is expanded.

  Default value: ''

*g:vimtex_view_mupdf_options*
  Set options for mupdf (|vimtex_viewer_mupdf|).

  Default value: ''

*g:vimtex_view_zathura_options*
  Set options for zathura (|vimtex_viewer_zathura|).

  Default value: ''

*g:vimtex_view_mupdf_send_keys*
  A string of keys that will be sent to MuPDF just after the PDF file has been
  opened.

  Default value: ''

*g:vimtex_syntax_minted*
  A list that contains dictionaries for each supported language.  A language
  dictionary should be something similar to the following: >

    {
      'lang'    : NAME,
      'syntax'  : SYNTAX-FILE-NAME,
      'ignored' : IGNORED-GROUPS
    }
<
  If the `syntax` entry is not present, then the `lang` entry is used as name of
  the syntax file.  The `ignored` entry is also optional, and is used to name
  syntax groups to ignore in the minted region.

  Default value: []

  Example for some languages: >

    let g:vimtex_syntax_minted = [
          \ {
          \   'lang' : 'c',
          \ },
          \ {
          \   'lang' : 'cpp',
          \   'environments' : ['cppcode', 'cppcode_test'],
          \ },
          \ {
          \   'lang' : 'csharp',
          \   'syntax' : 'cs'
          \ },
          \ {
          \   'lang' : 'python',
          \   'ignore' : [
          \     'pythonEscape',
          \     'pythonBEscape',
          \     ],

<                          When used as a normal mode mapping, the mapping
                          will act as an |operator| on the following motion or
                          text object. Finally, when used as a visual mode
                          mapping, it will act on the selected lines.

                          Note: This always works linewise!

:VimtexImapsList          Show the list of insert mode mappings created by the
                          |vimtex-imaps| feature. The mappings are displayed
                          in a scratch buffer. Press `q` or `<esc>` to close
                          the buffer.

                                             *VimtexToggleMain*
                                             *<plug>(vimtex-toggle-main)*
:VimtexToggleMain         In general, |vimtex| detects the main file for the
                          current LaTeX project and uses it for compilation
                          and many other features. However, in some cases it
                          may be useful to instead focus on the current file,
                          for instance in large projects. In such cases, one
                          can use |VimtexToggleMain| to change which file to
                          use as the "current project". It is easy to toggle
                          back and forth, and both the "main project" and the
                          "local project" can be used simultaneously if
                          desired (e.g. for compilation).

                          Note: To compile the current file when it is part of
                                a larger project, one must of course include
                                a preamble and the `\begin/\end{document}`! It is
                                possible to have a working preamble in every
                                file in a multi-file project with `subfiles`,
                                see |vimtex-subfiles|.

*vimtex-zx*
  When |vimtex| folding is enabled and when the manual mode is turned on
  (|g:vimtex_fold_manual|), then |vimtex| remaps |zx| and |zX| in such that
  the folds are refreshed appropriately.

*<plug>(vimtex-env-delete)*
*<plug>(vimtex-env-delete-math)*
*<plug>(vimtex-env-change)*
  Delete/Change surrounding environment.

*<plug>(vimtex-cmd-delete)*
*<plug>(vimtex-cmd-delete-math)*
*<plug>(vimtex-cmd-change)*
  Delete/Change surrounding command.

*<plug>(vimtex-env-toggle-star)*
  Toggle starred environment.

*<plug>(vimtex-delim-toggle-modifier)*
  Toggle delimiter modifiers, for instance between `(...)` and `\left(...\right)`.
  The normal mode mapping toggles the closes surrounding delimiter, whereas
  the visual mode mapping toggles all delimiters that are fully contained in
  the visual selection. The selection is preserved.

  See also |g:vimtex_delim_toggle_mod_list|.

*<plug>(vimtex-cmd-create)*
  Convert the current word (word under or right before the cursor) into
  a LaTeX command. That is, it prepends a backslash and adds an opening brace.
  From normal mode, the mapping will leave you in insert mode. The mapping
  works both in normal and in insert mode. It is by default mapped to <f7>
  (see |vimtex-default-mappings| for a list of the default mappings).

*<plug>(vimtex-delim-close)*
  Close the current environment or delimiter (insert mode).

*<plug>(vimtex-ac)*

Insert mode mappings~
                                                                 *vimtex-imaps*

Some LaTeX commands are very common, and so it is both natural and convenient
to have insert mode mappings/abbreviations for them. |vimtex| therefore
provides a list of such mappings that are enabled by default, see
|g:vimtex_imaps_list|. The mappings utilize a map leader defined by
|g:vimtex_imaps_leader|. The default list of maps are all math mode mappings,
but one may also add mappings that are available and useful outside of math
mode. To see the list of mappings that are created, one can use the command
|VimtexImapsList|, which is by default mapped to `<localleader>lm`.

It is of course possible to customize the list of mappings. First, one may
specifically disable a default mapping through |g:vimtex_imaps_disabled|.
Second, one may specify |g:vimtex_imaps_list|, which will overwrite the
default list. Finally, one may add new maps through calls to the function
|vimtex#imap#add_map|. The following are some examples of how to customize the
mappings: >

  " Disable \alpha and \beta mappings
  let g:vimtex_imaps_disabled = ['a', 'b']

  " Add custom mapping through vimtex#imap#add_map
  call vimtex#imaps#add_map({
    \ 'lhs' : 'test',
    \ 'rhs' : '\tested',
    \ 'wrapper' : 'vimtex#imaps#wrap_trivial'
    \})
<
                                                         *vimtex#imaps#add_map*

This function is used to add new insert mode mappings. It takes a single
dictionary argument: >

  map = {
    \ 'lhs' : lhs,
    \ 'rhs' : rhs,
    \ 'leader' : leader_key,
    \ 'wrapper' : function_name
    \ }

Explanation of the keys:

  lhs~
    Mandatory argument. The left-hand side part of the map.

  lhs_rhs~
    Mandatory argument. The right-hand side part of the map.

  leader~
    Custom leader key. If the key is not present, then |g:vimtex_imaps_leader|
    is used as leader key.

  wrapper~
    The name of a wrapper function that is used to generate the `rhs`. Two
    functions are available from |vimtex|:

      `vimtex#imaps#wrap_trivial`  Trivial wrapper: Simply returns `rhs`.
      `vimtex#imaps#wrap_math`     Only define `rhs` if inside a math environment.
                                 This is the default wrapper function and will
                                 be used if no other wrapper is supplied.

    Of course, one may use custom wrapper functions. To write a custom wrapper
    function, please see the source for examples on how the |vimtex| wrappers
    are written.

Note: that this feature is not the same as the snippet feature of |UltiSnips|
or |neosnippet|. The imaps feature of |vimtex| previously supported `automatic`
snippets, but these have been removed after careful considerations and input
from |vimtex| users, please see vimtex issue #295:
https://github.com/lervag/vimtex/issues/295#issuecomment-164262446
It has been decided that the best approach is to only provide basic mappings,
and to let users manully create automatic snippets through the anonymous
snippet functions in |UltiSnips| and |neosnippet|, please see |UltiSnips#Anon|
and |neosnippet#anonymous|, respectively. Here are a couple of examples that
show how to create such mappings: >

    " Using neosnippet#anonymous
    inoremap <silent><expr> __ neosnippet#anonymous('_${1}${0}')
    inoremap <silent><expr> ^^ neosnippet#anonymous('^${1}${0}')

    " Using UltiSnips#Anon
    inoremap <silent> __ __<c-r>=UltiSnips#Anon('_{$1}$0', '__', '', 'i')<cr>
    inoremap <silent> ^^ ^^<c-r>=UltiSnips#Anon('^{$1}$0', '^^', '', 'i')<cr>

Events~
                                                                *vimtex-events*

|vimtex| defines some events that may be used for further customization
through |autocmd|s, in particular the |User| autocmd.

  *VimtexEventQuit*
    This event is triggered when the last buffer for a particular LaTeX
    project is exited. The event may be used for instance to issue
    a |VimtexClean| command when exiting.

  *VimtexEventInitPost*
    This event is triggered after |vimtex| initialization is completed. It may
    be used to automatically start compiling a document.

Examples: >

  augroup vimtex_config
    au!
    au User VimtexEventQuit     VimtexClean
    au User VimtexEventInitPost VimtexCompile
  augroup END

==============================================================================
COMPLETION                                                  *vimtex-completion*

If |g:vimtex_complete_enabled| is 1 (default), then |vimtex| sets the
'omnifunc' to provide omni completion, see |compl-omni|.  Omni completion is
then accessible with |i_CTRL-X_CTRL-O|.

The omni completion completes citations, labels, glossary entries and
filenames. If desired, one may set |g:vimtex_complete_close_braces|, which
makes the completion include closing braces.

Associated settings:
  |g:vimtex_complete_enabled|
  |g:vimtex_complete_close_braces|
  |g:vimtex_complete_recursive_bib|

------------------------------------------------------------------------------
Complete citations~
                                                        *vimtex-complete-cites*

Citation completion is triggered by '\cite{' commands.  The completion parses
included bibliography files (`*.bib`) and `thebibliography` environments to
gather the completion candidates.

As an example, assume that a bibliography file is included with the following
entry: >

        @book { knuth1981,
                author = "Donald E. Knuth",
                title = "Seminumerical Algorithms",
                publisher = "Addison-Wesley",
                year = "1981" }

Then the bibliography key `knuth1981` will be completed with e.g.: >

        \cite{Knuth 1981<CTRL-X><CTRL-O>
        \cite{algo<CTRL-X><CTRL-O>
        \cite{Don.*Knuth<CTRL-X><CTRL-O>

In particular, note that regular expressions (or vim patterns) can be used
after '\cite{' to search for candidates.

                                                       *vimtex-complete-labels*

Label completion is triggered by '\ref{' commands.  The completion parses every
relevant aux file to gather the completion candidates.  This is important,
because it means that the completion only works when the LaTeX document has
been compiled.

As an example: >

        \ref{sec:<CTRL-X><CTRL-O>

offers a list of all matching labels, with their associated value and page
number.  The label completion matches:

    1. labels: >
        \ref{sec:<CTRL-X><CTRL-O>
<    2. numbers: >
        \eqref{2<CTRL-X><CTRL-O>
<    3. labels and numbers together (separated by whitespace): >
        \eqref{eq 2<CTRL-X><CTRL-O>

------------------------------------------------------------------------------
Complete file names for figures~
                                                       *vimtex-complete-images*

File name completion for figures is triggered by '\includegraphic{' commands.

By default, the paths are completed relative to the root path of the main
file. One can use the option |g:vimtex_complete_img_use_tail| to instead
complete only the tail part of file names. This is useful if one uses the
`graphicx` package and the `\graphicspath` command.

------------------------------------------------------------------------------
Complete input/include tex files~
                                                        *vimtex-complete-input*

File name completion for input/include files is triggered by '\input{',
'\include{', or '\includeonly{' commands.

------------------------------------------------------------------------------
Complete include PDF files~
                                                          *vimtex-complete-pdf*

File name completion for PDF files offered by the `pdfpages` package is
triggered by '\includepdf{' commands.

------------------------------------------------------------------------------
Complete include standalone files~
                                                   *vimtex-complete-standalone*

File name completion for standalone files offered by the package `standalone`
is triggered by '\includepdf{' commands.

------------------------------------------------------------------------------
Complete include glossary entries~
                                                     *vimtex-complete-glossary*

Glossary entry completion from the `glossaries` package are triggered by the
commands '\gls{', '\glspl{' and their variations.

------------------------------------------------------------------------------
Autocomplete~
                                                         *vimtex-complete-auto*

Vim does not provide automatic completion by itself, but there exist at least
two good plugins that provide this: |neocomplete| and |youcompleteme|.  Moreover,
there is |VimCompletesMe| that overrides <tab> to trigger different built-in
completions, such as the omni-completion by vimtex, depending on the context.
See below for descriptions on how to setup these with |vimtex|.

neocomplete~
                                                  *vimtex-complete-neocomplete*
|neocomplete| is my preferred choice for an automatic completion engine in vim.
The plugin is available here: https://github.com/Shougo/neocomplete.vim.

The following options may be used to enable automatic completion for LaTeX
documents with |neocomplete| and |vimtex|s omni completion function: >

  if !exists('g:neocomplete#sources#omni#input_patterns')
    let g:neocomplete#sources#omni#input_patterns = {}
  endif
  let g:neocomplete#sources#omni#input_patterns.tex =
        \ '\v\\%('
        \ . '\a*cite\a*%(\s*\[[^]]*\]){0,2}\s*\{[^}]*'
        \ . '|\a*ref%(\s*\{[^}]*|range\s*\{[^,}]*%(}\{)?)'
        \ . '|hyperref\s*\[[^]]*'
        \ . '|includegraphics\*?%(\s*\[[^]]*\]){0,2}\s*\{[^}]*'
        \ . '|%(include%(only)?|input)\s*\{[^}]*'
        \ . '|\a*(gls|Gls|GLS)(pl)?\a*%(\s*\[[^]]*\]){0,2}\s*\{[^}]*'
        \ . '|includepdf%(\s*\[[^]]*\])?\s*\{[^}]*'
        \ . '|includestandalone%(\s*\[[^]]*\])?\s*\{[^}]*'
        \ . ')'

deoplete~
                                                     *vimtex-complete-deoplete*
|deoplete| is similar to |neocomplete|, but is written specifically for Neovim, see
here: https://github.com/Shougo/deoplete.nvim. To configure for `vimtex`, one
may use: >

  if !exists('g:deoplete#omni#input_patterns')
      let g:deoplete#omni#input_patterns = {}
  endif
  let g:deoplete#omni#input_patterns.tex = '\\(?:'
        \ .  '\w*cite\w*(?:\s*\[[^]]*\]){0,2}\s*{[^}]*'
        \ . '|\w*ref(?:\s*\{[^}]*|range\s*\{[^,}]*(?:}{)?)'
        \ . '|hyperref\s*\[[^]]*'
        \ . '|includegraphics\*?(?:\s*\[[^]]*\]){0,2}\s*\{[^}]*'
        \ . '|(?:include(?:only)?|input)\s*\{[^}]*'
        \ . '|\w*(gls|Gls|GLS)(pl)?\w*(\s*\[[^]]*\]){0,2}\s*\{[^}]*'
        \ . '|includepdf(\s*\[[^]]*\])?\s*\{[^}]*'
        \ . '|includestandalone(\s*\[[^]]*\])?\s*\{[^}]*'
        \ .')'

Note: I don't personally use |deoplete|, and I have not tested the above
      expression. Please let me know if the regex does not work as intended,
      so that we can update it appropriately.

YouCompleteMe~
                                                *vimtex-complete-youcompleteme*
|youcompleteme| is probably the most popular code-completion engine for Vim.  The
github repository is here: https://github.com/Valloric/YouCompleteMe.
It is described as:

> YouCompleteMe is a fast, as-you-type, fuzzy-search code completion engine
> for Vim. It has several completion engines: an identifier-based engine that
> works with every programming language, a semantic, Clang [3]-based engine
> that provides native semantic code completion for the C-family languages,
> a Jedi [4]-based completion engine for Python, an OmniSharp [5]-based
> completion engine for C# and an omnifunc-based completer that uses data from
> Vim's omnicomplete system to provide semantic completions for many other
> languages (Ruby, PHP etc.).

To enable automatic completion with |youcompleteme|, use the following options: >

  if !exists('g:ycm_semantic_triggers')
    let g:ycm_semantic_triggers = {}
  endif
  let g:ycm_semantic_triggers.tex = [
        \ 're!\\[A-Za-z]*cite[A-Za-z]*(\[[^]]*\]){0,2}{[^}]*',
        \ 're!\\[A-Za-z]*ref({[^}]*|range{([^,{}]*(}{)?))',
        \ 're!\\hyperref\[[^]]*',
        \ 're!\\includegraphics\*?(\[[^]]*\]){0,2}{[^}]*',
        \ 're!\\(include(only)?|input){[^}]*',
        \ 're!\\\a*(gls|Gls|GLS)(pl)?\a*(\s*\[[^]]*\]){0,2}\s*\{[^}]*',
        \ 're!\\includepdf(\s*\[[^]]*\])?\s*\{[^}]*',
        \ 're!\\includestandalone(\s*\[[^]]*\])?\s*\{[^}]*',
        \ ]
<
VimCompletesMe~
                                                          *vimtex-complete-vcm*
A plugin that maps <tab> to trigger the built-in completion that is most
suitable to the current contex.  The plugin is available here:
https://github.com/ajh17/VimCompletesMe.

The following options may be used to enable completion with the <tab> trigger
for LaTeX documents with |VimCompletesMe| and |vimtex|s omni completion function: >

  augroup VimCompletesMeTex
    autocmd!
    autocmd FileType tex let b:vcm_omni_pattern = <neocomplete-pattern>
  augroup END
<
Note: Here `<neocomplete-pattern>` is the same pattern as was defined above
      for neocomplete.

==============================================================================
FOLDING                                                        *vimtex-folding*

|vimtex| can fold documents according to the LaTeX structure (part, chapter,
section and subsection).  Folding is turned off by default, but it can be
enabled if desired, either through the option |g:vimtex_fold_enabled|, or
manually with >

  set foldmethod=expr
  set foldexpr=vimtex#fold#level(v:lnum)
  set foldtext=vimtex#fold#text()

When folding is enabled and a LaTeX document is opened, the document is parsed
in order to define the highest fold level based on which parts (such as
frontmatter, backmatter, and appendix) and section types (chapter, section,
etc.) are present. This parsing is done automatically every time the folds are
recomputed, if there are any changes to the file.

The fold function also recognizes "fake" sections. That is, it parses comments
similar to: >

  % Fakepart title
  % Fakechapter title
  % Fakesection title
  % Fakesubsection title

The fake sections are folded at the same level as the corresponding "real"
sections. The fold title is the provided title with the `Fake...` part
prepended.

Note: The |fold-expr| method of folding is well known to be slow, e.g. for
      long lines and large files. To speed things up, the user may want to
      enable the |g:vimtex_fold_manual| option. An alternative is to add
      a dedicated plugin that improves folding speed for the slow fold
      methods, e.g. https://github.com/Konfekt/FastFold.

In order to get slightly cleaner fold text, I recommend setting the global
'fillchars' option.  To preserve the default vertical separator and only
change the fold filler, use e.g.: >

  set fillchars=vert:|,fold:\

Associated settings:

  |g:vimtex_fold_sections|
  |g:vimtex_fold_envs|
  |g:vimtex_fold_usepackage|

==============================================================================
INDENTATION                                                     *vimtex-indent*
                                                            *vimtex-bib-indent*

|vimtex| provides custom indentation functions both for LaTeX documents and
for bibliography files (`.bib` files).

Associated settings:
    |g:vimtex_indent_enabled|
    |g:vimtex_indent_bib_enabled|

==============================================================================
SYNTAX HIGHLIGHTING                                             *vimtex-syntax*

Vim ships with syntax highlighting for LaTeX documents out of the box, please
see |ft-tex-syntax|.  |vimtex| therefore does not provide its own syntax
highlighting.  However, |vimtex| does add some minor improvements:

- Support for `biblatex` and `natbib` package
- Support for `cleveref` package
- Improved highlighting of `listings` package
- Nested syntax highlighting for `dot2tex`
- Nested syntax highlighting for `minted` (see |g:vimtex_syntax_minted|)

Before enabling additional syntax highlighting, |vimtex| also checks the
|g:tex_fast| variable (defined by |ft-tex-syntax|) that allows one to
selectively enable or disable highlighting for specific groups.  If
|g:tex_fast| is set, additional syntax highlighting for bold, italic, and
reference groups are enabled only if they are explicitly allowed.

==============================================================================
NAVIGATION                                                  *vimtex-navigation*
                                                                 *vimtex-index*

The |vimtex-index| is an interface that is used to display lists and indexes
in vertically or horizontally split windows.  It supports custom keybindings
inside the index window, including actions on the list elements.  The position
of the window is controlled by |g:vimtex_index_split_pos|.  By default, the
top of the buffer will display help text to explain the local keybindings.
This may be turned off with |g:vimtex_index_show_help|.

The |vimtex-index| interface is used by the table of contents |vimtex-toc| and
the table of labels |vimtex-labels|.

Associated settings:
  |g:vimtex_index_hide_line_numbers|
  |g:vimtex_index_resize|
  |g:vimtex_index_show_help|
  |g:vimtex_index_split_pos|
  |g:vimtex_index_split_width|

Table of contents~
                                                                   *vimtex-toc*

|vimtex-toc| shows a table of contents (ToC) for the current LaTeX document.
The ToC entries may be activated/jumped to with <cr> or <space>.  The local
keybindings are described if |g:vimtex_index_show_help| is enabled.

Associated settings:
    |g:vimtex_toc_enabled|
    |g:vimtex_toc_fold|
    |g:vimtex_toc_fold_levels|
    |g:vimtex_toc_number_width|

|vimtex-labels| shows a table of labels similar to the ToC.  The table entries
may be filtered with the `f` keybinding.  Filters may be removed with the `c`
keybinding.

Associated settings:
    |g:vimtex_labels_enabled|

------------------------------------------------------------------------------
Unite sources~
                                                                 *vimtex-unite*
                                                                   *vimtex_toc*
                                                                *vimtex_labels*

                                          https://github.com/Shougo/unite.vim
The |unite.vim| plugin is a popular interface for many things, including
outlines. Although |vimtex| includes a simple interface for tables of contents
and labels, it also makes sense to provide these as sources to |unite.vim|.
The source names are:

  vimtex_toc       Table of contents
  vimtex_labels    Table of labels

The sources use similar syntax highlighting to the internal |vimtex|
interfaces.

If one prefers the |unite.vim| sources to the |vimtex| interface, one may
override the default mappings, e.g.: >

  nnoremap <localleader>lt :<c-u>Unite vimtex_toc<cr>
  nnoremap <localleader>ly :<c-u>Unite vimtex_labels<cr>

==============================================================================
LATEXMK                                                        *vimtex-latexmk*

                      http://users.phys.psu.edu/~collins/software/latexmk-jcc
> latexmk is a perl script for running LaTeX the correct number of times to
> resolve cross references, etc; it also runs auxiliary programs (bibtex,
> makeindex if necessary, and dvips and/or a previewer as requested).  It has
> a number of other useful capabilities, for example to start a previewer and
> then run latex whenever the source files are updated, so that the previewer

|vimtex| uses `latexmk` to compile the LaTeX document.  It utilizes by default
the preview continuous mode.  This means that after the compilation is turned
on, `latexmk` will automatically recompile when any LaTeX project file is
changed.

If one prefers to have single shot compilations, one may disable the
continuous mode with |g:vimtex_latexmk_continuous|.  If it is disabled, then
the option |g:vimtex_latexmk_background| may be used to decide if single shot
compilation should run in the foreground or the background.

Regardless of the |g:vimtex_latexmk_continuous| option, single shot
compilation may always be issued with |VimtexCompileSS|.

It is also possible to compile a selection of the file. To do this, one may
either use the mapping, |<plug>(vimtex-compile-selected)|, or the command
|VimtexCompileSelected|. This will compile the selected text by copying it to
a temporary file with the same preamble as the current file. It will be
compiled similarly to a single shot compile, and if there are errors, they
will be shown in the quickfix list. For more info, see
|VimtexCompileSelected|.

|vimtex| passes a "sensible" default set of options to `latexmk`. This may be
customized with |g:vimtex_latexmk_options|, where the default options are also
described.

If vim is compiled with the |+clientserver| option and if
|g:vimtex_latexmk_callback| is enabled (which it is by default), then
compilation errors will be parsed automatically.  This is done by utilizing
the tricks explained in |vimtex-latexmk-tricks|.  Note that this only works
for continuous compilation mode.  One can always check for compilation errors
with |VimtexErrors|.

Associated settings:
    |g:vimtex_latexmk_enabled|
    |g:vimtex_latexmk_callback|
    |g:vimtex_latexmk_callback_hooks|
    |g:vimtex_latexmk_autojump|
    |g:vimtex_latexmk_continuous|
    |g:vimtex_latexmk_background|
    |g:vimtex_latexmk_options|

------------------------------------------------------------------------------
Latexmk tricks~
                                                        *vimtex-latexmk-tricks*

One may customize the `latexmk` options through |g:vimtex_latexmk_options|.
However, one may also configure `latexmk` explicitly through a global
`~/.latexmkrc` file, or a project specific `.latexmkrc` file. It is important
to know that command line arguments have priority, so one may want to use
custom options if one wants to specify particular things in a configuration
file.

A particular set of options are very convenient for a good coupling between
`latexmk` and Vim: `$compiling_cmd`, `$success_cmd`, and `$failure_cmd`.  These options
can be used to specify commands that are run by `latexmk` before and after
compilation.  This is used by |vimtex| to achieve callbacks after compilation
has finished with something like this: >

  $success_cmd = "gvim --remote-expr 'vimtex#latexmk#callback(1)'";
  $failure_cmd = "gvim --remote-expr 'vimtex#latexmk#callback(0)'";

Another neat way to use this is to use `xdotool` to change the window title of
the viewer to indicate the compilation status: >

  $compiling_cmd = "xdotool search --name \"%D\" " .
                   "set_window --name \"%D compiling...\"";
  $success_cmd   = "xdotool search --name \"%D\" " .
                   "set_window --name \"%D OK\"";
  $failure_cmd   = "xdotool search --name \"%D\" " .
                   "set_window --name \"%D FAILURE\"";

Note: If you define these options similar to the above `xdotool` trick and
      still want to enable the |vimtex| callbacks, then one must include
      a semicolon at the end of the `cmd` strings so that |vimtex| may append
      safely to the options.

Note: More info on `xdotool` here: http://www.semicomplete.com/projects/xdotool.

------------------------------------------------------------------------------
Lacheck~
                                                       *vimtex-latexmk-lacheck*

After compilation of a LaTeX document, the log file will contain errors that
are parsed by |vimtex| as explained above.  However, there are syntax checkers
for LaTeX.  |vimtex| provides a simple interface to `lacheck` for checking
LaTeX manuscripts for errors.  This is available through |VimtexLacheck|.

==============================================================================
VIEW                                                              *vimtex-view*

|vimtex| provides the command |VimtexView| to open the desired viewer.  The
command is mapped to '<localleader>lv' by default.  The list of supported
viewers are given in the description of |g:vimtex_view_method|.

For supported viewers, |VimtexView| will also perform forward search when the
viewer is opened.

Associated settings:
    |g:vimtex_view_enabled|
    |g:vimtex_view_method|
    |g:vimtex_view_use_temp_files|
    |g:vimtex_view_general_viewer|
    |g:vimtex_view_<viewer>_options|

------------------------------------------------------------------------------
Synctex support~
                                                               *vimtex-synctex*

Synctex is a tool that enables synchronization of the text editor position and
the pdf viewer position.  The tool may be used to add mappings in vim to go to
the current position in the compiled pdf document (forward search), and also
to go from a specific position in the pdf file to the corresponding position
in vim (inverse/backward search).

To make synctex work, it must be enabled. vimtex enables this by default by
passing `-synctex=1` on the command line, unless the user sets the option
|g:vimtex_latexmk_options| to a nonempty value. In the latter case, the user
should ensure that the synctex flag is passed, i.e. with: >

  let g:vimtex_latexmk_options = '... -synctex=1 ...'

Alternatively, one can put this in ones `~/.latexmkrc` file: >

  $pdflatex = 'pdflatex -synctex=1 %O %S';

------------------------------------------------------------------------------
Forward search~
                                                *vimtex-synctex-forward-search*

For supported viewers, |VimtexView| (<localleader>lv) will issue a forward
search if the viewer is already opened.  The forward search will take you to
the page or position in the viewer that corresponds to the current line in
your vim session.  See |g:vimtex_view_method| for a list of supported viewers.

------------------------------------------------------------------------------
Backward search~
                                               *vimtex-synctex-backward-search*
                                                *vimtex-synctex-inverse-search*

In supported viewers one may set up backward or inverse search.  When
correctly set up, this allows one to go directly from a selected line in the
viewer (typically by double clicking with the mouse or something similar) to
the corresponding line inside the Vim instance.

Backward search is typically set up inside the specific viewer through an
option named something like "inverse search command-line".  A standard value
for the option is: >

  gvim --remote-silent +%l "%f"

Note: Inverse search relies on the |clientserver| functionality of vim.  Each
      instance of vim runs its own server.  The above mentioned standard value
      implies the default server name, which might not be the actual name of
      the server for the vim instance you are using.

Note: For backward search to work on windows, one must ensure that the folder
      that contains `gVim.exe` is in your `%PATH%` environment variable.

==============================================================================
CODE STRUCTURE                                                    *vimtex-code*

The |vimtex| code is based on the |autoload| feature of vim.  For each new
latex buffer, the function *vimtex#init* initializes the variables and
functionalities based on the desired options |vimtex-options|.  The first run
performs some global initialization, which is mainly to define autocommands.
Other functionality is provided by additional autoloaded scripts.  Every
additional script should have an initialization script that sets default
commands and mappings, creates autocommands and performs other necessary
initialization.  This initialization script is then called from 'vimtex#init'.

For each LaTeX project that is opened, a |Dictionary| is created and added to
the list 'g:vimtex_data'.  The dictionary is initialized with data tied to the
current project.  The dictionary is also linked to the buffer variable
'b:vimtex'.  Note that a project might consist of several files, so for
a multi-file project one may have several buffers that are linked to the same
data blob.  This is by design, and enabled vimtex |vimtex| to work properly
for multi-file latex projects.  It also allows the editing of different latex
projects simultaneously in different buffers.

The command |VimtexInfo| (mapped to <localleader>li by default) will show the
contents of the local data blob.

FAQ                                                                *vimtex-faq*

                                                          *vimtex-faq-surround*
Q: |vimtex| provides `dse`, `dsc`, `cse`, and `csc`.  These seem to be inspired by
   |surround.vim|.  Does |vimtex| also provide the corresponding `yse` and `ysc`?
A: The mentioned mappings are indeed inspired by |surround.vim|.  However,
   |vimtex| does not provide `yse` and `ysc`.  If you use |surround.vim|, then
   the asked for mappings may be easily added if one adds the following lines
   to ones `vimrc` file: >

  augroup latexSurround
     autocmd!
     autocmd FileType tex call s:latexSurround()
  augroup END

  function! s:latexSurround()
     let b:surround_{char2nr("e")}
       \ = "\\begin{\1environment: \1}\n\t\r\n\\end{\1\1}"
     let b:surround_{char2nr("c")} = "\\\1command: \1{\r}"
  endfunction

Q: Vim throws error when jumping to file with |gf|.
A: This might be due to the |isfname| setting, which by default contains `{,}`
   on windows.  |isfname| is a global option, and can therefore not be set by
   `vimtex`.  Suggested solution is to remove `{,}` from |isfname| by: >

  set isfname-={,}
<
                                                            *vimtex-faq-neovim*
Q: Does |vimtex| work with neovim?
A: Yes. Most features work out of the box, but the `latexmk` coupling and some
   of the viewer functionality require the |--remote| options from the
   |clientserver|. For some reason, these options have been removed from
   neovim, see #1750 [0]. There does remain some hope that the options will be
   reimplemented sometime in the future.

   In the meantime, there exists a workaround: `neovim-remote` [1] is a simple
   tool that implements the |--remote| options through a python script. If one
   downloads this tool and sets the option |g:vimtex_latexmk_progname| to
   `nvr` (or the full path, if `nvr` is not in `$PATH`), then everything
   should work.

Q: How can I jump from a `\ref{label}` to the corresponding label?
A: This is not a feature provided by |vimtex| itself, but vim has very good
   support for tag navigation, see |tags-and-searches|. It is worth mentioning
   that the |ctags| support for LaTeX is somewhat lacking. This can be amended
   by adding some lines to your `~/.ctags` configuration file, e.g.: >

    --langdef=tex2
    --langmap=tex2:.tex
    --regex-tex2=/\\label[ \t]*\*?\{[ \t]*([^}]*)\}/\1/l,label/

<   See [0,1] for references. I also find |gutentags| [2] to be very convenient
   for automatically generating and updating tag files.

Troubleshooting                                       *vimtex-troubleshooting*

With different operating systems and different plugin configurations, there
are a few things that must be considered for system interoperability. A number
of common problems and suggested solutions are included in the following
troubleshooting section.

Problem: The user wants to use vim-polyglot~

This is a problem, because vim-polyglot [0] includes and enables LaTeX-Box by
default. LaTeX-Box will not work well with vimtex, e.g. because of conflicting
mappings.

Suggested solution: Don't use vim-polyglot.

[0]: https://github.com/sheerun/vim-polyglot

Problem: Upon starting continuous compilation the status bar indicates~
   'latexmk compile: started continuous mode' but compilation never terminates~
   and the quickfix window does not load.~

Tips:
1. Ensure that a latexmk process and a Perl process have started. If they have
   not been started, then these two programs may not accessible given your
   operating system's PATH environment variable.
2. On Windows, some releases of Perl have been known to not trigger callbacks
   upon successful/failed compilation. It is highly suggested to install a
   dedicated Perl distribution (e.g. Strawberry Perl). See
   https://github.com/lervag/vimtex/issues/378 for more information.
3. Ensure that the option `-interaction=nonstopmode` is provided to latexmk.
   This is done by default by vimtex, unless the user provides custom options
   through |g:vimtex_latexmk_options|. In the latter case, the user must
   ensure that the said option is also provided.

Problem: In Windows, environment text object commands, like `vae` and `vie`, do~
  not select the entire body of the environment.~

  More specifically, given: >

    \begin{someenv}
      some content
    \end{someenv}

<  The command `dae` results in: >

    }

<  and `die` results in: >

    \begin{someenv}
      t
    \end{someenv}

Solution: It seems that vim for Windows comes with some options set by default
in the vimrc file. One of these has been reported to be `:behave mswin` (see
|:behave)| which, among other things, sets the 'selection' option to
"exclusive". This can be ameliorated by pursuing one of two options:

  1) Add `:behave xterm` to your vimrc file.
  2) Add `:set selection=inclusive` to your vimrc file.

CHANGELOG                                                    *vimtex-changelog*

The following changelog only logs particularly important changes, such as
changes that break backwards compatibility.  See the git log for the detailed
changelog.

2016-05-31: A lot of things have updated~
I know that people would like to see a simple list of changes. Unfortunately,
I am bad at keeping this changelog updated. All details are available in the
git log, though. The reason I added this entry is to note that I have removed
an option:

  *g:vimtex_env_complete_list* --- It is no longer necessary. Completion
                                 candidates are instead parsed from the
                                 project.

2016-02-06: Large refactoring of delimiter parsing~
I've refactored a lot of the code in order to make the parsing of delimiters
and features that rely on delimiter detection and similar more consistent.
This results in some changes in option names and similar, but it should make
it easier to provide improved and more robust features.

There is one feature change: The delimiter toggle now consistently toggles the
modifier, not the delimiter itself, and it toggles between a range of
modifiers by default. For customization, see |g:vimtex_delim_toggle_mod_list|.

The following options have changed names:
  *g:vimtex_change_set_formatexpr* ---> |g:vimtex_format_enabled|
  *g:vimtex_change_complete_envs*  ---> |g:vimtex_env_complete_list|
  *g:vimtex_change_toggled_delims* ---> |g:vimtex_delim_toggle_mod_list|

The following options have been removed:
  *g:vimtex_change_ignored_delims_pattern* --- It was no longer necessary

The following mappings have been renamed:
   *<plug>(vimtex-delete-env)*   ---> |<plug>(vimtex-env-delete)|
   *<plug>(vimtex-delete-cmd)*   ---> |<plug>(vimtex-cmd-delete)|
   *<plug>(vimtex-change-env)*   ---> |<plug>(vimtex-env-change)|
   *<plug>(vimtex-change-cmd)*   ---> |<plug>(vimtex-cmd-change)|
   *<plug>(vimtex-toggle-star)*  ---> |<plug>(vimtex-env-toggle-star)|
   *<plug>(vimtex-toggle-delim)* ---> |<plug>(vimtex-delim-toggle-modifier)|
   *<plug>(vimtex-create-cmd)*   ---> |<plug>(vimtex-cmd-create)|
   *<plug>(vimtex-close-env)*    ---> |<plug>(vimtex-delim-close)|

2015-10-19: Added convenient insert mode mappings~
I've merged the `math_mappings` branch (see #172 and #251). It adds the
feature that is explained in |vimtex-imaps|.

2015-06-06: Minor but convenient restructuring (++)~
I've changed a lot of the code structure in relatively small ways.  For
instance, instead of referring to the particular data blobs through the global
array, I instead linked a buffer variable to the correct global array element.

One particular change is that all modules are now initialized in three steps:

  1. Initialize module options
  2. Initialize script variables and single execution functionalities
  3. Initialize buffer options

Finally, I've cleaned up a lot of the code by removing some deprecation
warnings and similar.

2015-03-21: Implemented index buffers, deprecated vimtex_toc filetype~
The system for displaying the table of content relied on a dedicated filetype
plugin.  This was inherited from LaTeX-Box, and worked quite well.  However,
I intend to implement more functionality that uses the same kind of buffer to
display similar things, such as a list of labels.  I realized I wanted the ToC
window to be more adaptable, so I implemented the `index` interface for such
buffers.  The `index` in itself may be used to create ToC-like buffers with
simple actions.  The |vimtex-toc| uses and expands the `index` in such a way
that the changes should barely be noticeable from the user perspective.  Note
however the following variable name changes:

  *g:vimtex_toc_numbers_width*     ---> |g:vimtex_toc_number_width|
  *g:vimtex_toc_hide_preamble*     ---> |g:vimtex_toc_show_preamble|
  *g:vimtex_toc_numbers*           ---> |g:vimtex_toc_show_numbers|

  *g:vimtex_toc_hide_line_numbers* ---> |g:vimtex_index_hide_line_numbers|
  *g:vimtex_toc_resize*            ---> |g:vimtex_index_resize|
  *g:vimtex_toc_hide_help*         ---> |g:vimtex_index_show_help|
  *g:vimtex_toc_split_pos*         ---> |g:vimtex_index_split|
  *g:vimtex_toc_width*             -/

                                                         *vim-latex-namechange*
2015-03-08: Changed the name to vimtex~
The old name `vim-latex` was already used by LaTeX-Suite.  I was not aware of
the name clash in the beginning.  Due to the rising popularity of this plugin,
it has become clear that such a name clash is very inconvenient.  The present
change is therefore very much needed.

The name change is reflected throughout the plugin in the names of commands,
mappings, functions, and options.  People should update their `vimrc` settings
accordingly.  For instance, every option name should be changed from >

  g:latex_... = ...

to >

  g:vimtex_... = ...

2014-12-07: Added more general view functionality~
Added new module for view functionality.  This allows more complex view
functions (and commands), for instance to do forward (and possibly backwards)
searching through `synctex`.  In the first version, I added forward search for
mupdf by use of the `synctex` command and `xdotools`.

The `g:latex_viewer` option has now been deprecated.  Instead one should use
|g:vimtex_view_method| and |g:vimtex_view_general_viewer|.

Deprecated option:
  *g:latex_viewer*

2014-06-13: Changed some option names~
Some |vimtex| option names were changed in an attempt to make the names
more consistent.  These options are listed here for reference:
  *g:latex_errorformat_ignore_warnings*
  *g:latex_errorformat_show_warnings*
  *g:latex_latexmk_autojump*
  *g:latex_latexmk_quickfix*
The new names are, respectively:
  |g:vimtex_quickfix_ignored_warnings|
  |g:vimtex_quickfix_ignore_all_warnings|
  |g:vimtex_quickfix_autojump|
  |g:vimtex_quickfix_mode|

2013-10-05: First public release~
