INTRO                                                            *signify-intro*

Signify (or just Sy) is a quite unobtrusive plugin. It uses signs to indicate
added, modified and removed lines based on data of an underlying version
control system.

==============================================================================
USAGE                                                            *signify-usage*

The usage is pretty straight-forward. By default you should only notice a
difference, if you're working in a directory that is managed by a supported
version control system and the current file was changed since the last commit.

Supported VCS:~
>
    git
    mercurial
    darcs
    bzr
    subversion
    cvs
    rcs
    fossil
    accurev
    perforce
<
Sign explanation:~

    `+`     This line was added.

    `!`     This line was modified.

    `_1`    The number of deleted lines below this sign. If the number is larger
    `99`    than 9, the `_` will be omitted. For numbers larger than 99, `_>`
    `_>`    will be shown instead.

    `!1`    This line was modified and a number of lines below were deleted.
    `!>`    It is a combination of `!` and `_`. If the number is larger than 9,
            `!>` will be shown instead.

    `‾`     The first line was removed. It's a special case of the `_` sign.

==============================================================================
OPTIONS                                                        *signify-options*

Put these variables into your vimrc. The provided examples also indicate the
default values, as long as no "Default:" section is given.

All available options:~

    |g:signify_vcs_list|
    |g:signify_disable_by_default|
    |g:signify_mapping_next_hunk|
    |g:signify_mapping_prev_hunk|
    |g:signify_mapping_toggle_highlight|
    |g:signify_mapping_toggle|
    |g:signify_skip_filetype|
    |g:signify_skip_filename|
    |g:signify_update_on_bufenter|
    |g:signify_update_on_focusgained|
    |g:signify_line_highlight|
    |g:signify_sign_delete_first_line|
    |g:signify_sign_delete|
    |g:signify_sign_change|
    |g:signify_sign_add|
    |g:signify_cursorhold_normal|
    |g:signify_cursorhold_insert|
    |g:signify_difftool|
    |g:signify_diffoptions|

------------------------------------------------------------------------------
                                                            *g:signify_vcs_list*
>
    let g:signify_vcs_list = [ 'git', 'hg' ]
<
Default: empty
Possible values: 'accurev'
                 'bzr'
                 'cvs'
                 'darcs'
                 'fossil'
                 'git'
                 'hg'
                 'perforce'
                 'rcs'
                 'svn'

NOTE: This is the most important option, so read closely.

It determines the VCS to check for and in what order. If you only use git and
mercurial, you can shorten the list to the shown example. If you use mostly
mercurial and only sometimes git, put 'hg' in the front of the list. It's
basically a priority list.

This can improve buffer loading time since by default all supported and
installed VCS will be checked for, so you are advised to change this option to
your needs. (This only happens once at the first time the signs get updated.
Afterwards, the VCS will be remembered anyway.)

NOTE: Some VCS rely on a an external diff tool to work properly (svn, darcs,
bzr, fossil), thus you have to make sure that Vim can find a valid diff tool.
So either the one you set through |g:signify_difftool| or "diff" by default.

NOTE: If you don't set this option and Sy is activated, updating signs for a
non-VCS file can lead to significant delay since all supported and installed
VCS will be tested for.

------------------------------------------------------------------------------
                                                  *g:signify_disable_by_default*
>
    let g:signify_disable_by_default = 0
<
Don't run Sy by default. You can toggle it anytime via :SignifyToggle.

------------------------------------------------------------------------------
                                                   *g:signify_mapping_next_hunk*
                                                   *g:signify_mapping_prev_hunk*
>
    let g:signify_mapping_next_hunk = '<leader>gj'
    let g:signify_mapping_prev_hunk = '<leader>gk'
<
Mapping for jumping to the start of the next or previous hunk.

Alternatively, you can also map it yourself:
>
    nmap <leader>gj <plug>(signify-next-hunk)
    nmap <leader>gk <plug>(signify-prev-hunk)
<
There is no difference between both variants.

------------------------------------------------------------------------------
                                            *g:signify_mapping_toggle_highlight*
>
    let g:signify_mapping_toggle_highlight = '<leader>gh'
<
Mapping for toggling line highlighting for lines containing changes.

------------------------------------------------------------------------------
                                                      *g:signify_mapping_toggle*
>
    let g:signify_mapping_toggle = '<leader>gt'
<
Mapping for toggling the plugin for the current buffer only.

------------------------------------------------------------------------------
                                                       *g:signify_skip_filetype*
                                                       *g:signify_skip_filename*
>
    let g:signify_skip_filetype = { 'vim': 1, 'c': 1 }
    let g:signify_skip_filename = { '/home/user/.vimrc': 1 }
<
Don't activate the plugin for these filetypes and/or filenames.

NOTE: Filenames have to be absolute paths.

Default: Both are empty.

------------------------------------------------------------------------------
                                                  *g:signify_update_on_bufenter*
>
    let g:signify_update_on_bufenter = 0
<
Update signs when entering a buffer that was modified.

NOTE: This also saves the buffer to disk!

------------------------------------------------------------------------------
                                               *g:signify_update_on_focusgained*
>
    let g:signify_update_on_focusgained = 0
<
Update signs when Vim gains focus.

------------------------------------------------------------------------------
                                                      *g:signify_line_highlight*
>
    let g:signify_line_highlight = 0
<
Enable line highlighting in addition to using signs by default.

------------------------------------------------------------------------------
                                              *g:signify_sign_delete_first_line*
                                              *g:signify_sign_delete*
                                              *g:signify_sign_change*
                                              *g:signify_sign_add*

    let g:signify_sign_add               = '+'
    let g:signify_sign_change            = '!'
    let g:signify_sign_delete            = '_'
    let g:signify_sign_delete_first_line = '‾'
<
The sign to use if a line was added, deleted or changed or a combination of
these.

------------------------------------------------------------------------------
                                                   *g:signify_cursorhold_normal*
                                                   *g:signify_cursorhold_insert*
>
    let g:signify_cursorhold_normal = 0
    let g:signify_cursorhold_insert = 0
<
Additionally trigger sign updates in normal or insert mode after 'updatetime'
miliseconds without any keypresses. This fires only once between keypresses,
thus not every 'updatetime' miliseconds.

NOTE: This also saves the buffer to disk!

------------------------------------------------------------------------------
                                                            *g:signify_difftool*
>
    let g:signify_difftool = 'gnudiff'
<
This will avoid the attempt to find the proper diff tool for version control
systems that rely on an external diff tool that supports the -U0 flag. These
are: svn, bzr, darcs, fossil.

Default: "diff"

------------------------------------------------------------------------------
                                                         *g:signify_diffoptions*
>
    let g:signify_diffoptions = { 'git': '-w', 'hg': '-w' }
<
This will pass the given additional options to the selected VCS diff command.

Default: Does not exist.

==============================================================================
COMMAND                                                       *signify-commands*
MAPPINGS                                                      *signify-mappings*
>
    :SignifyToggle
<
Toggle the plugin for the current buffer only.
Default mapping:  <leader>gt

------------------------------------------------------------------------------
>
    :SignifyToggleHighlight
<
Toggle line highlighting for lines containing changes.
Default mapping:  <leader>gh

==============================================================================
OBJECTS                                                        *signify-objects*

Sy also provides text objects that operate on the current hunk:
>
    ic
>
Operate on all the lines of the current hunk.
>
    ac
<
Does the same as ic and also removes all trailing empty lines.

NOTE: Don't be surprised that this also works with "deleted lines".

==============================================================================
COLORS                                                          *signify-colors*

This plugin defines highlighting groups for two different places: for lines
and signs. Per default these don't really exist but are linked to the standard
highlighting groups: DiffAdd, DiffChange, DiffDelete:
>
    highlight link SignifyLineAdd    DiffAdd
    highlight link SignifyLineChange DiffChange
    highlight link SignifyLineDelete DiffDelete

    highlight link SignifySignAdd    DiffAdd
    highlight link SignifySignChange DiffChange
    highlight link SignifySignDelete DiffDelete
<
Thus if you do not want to change the standard highlighting groups, but want
different colors for either your signs or lines, you can define one of these 6
Signify groups yourself in your vimrc.

Personally I use (256 colors terminal):
>
    " highlight lines in Sy and vimdiff etc.)

    highlight DiffAdd           cterm=bold ctermbg=none ctermfg=119
    highlight DiffDelete        cterm=bold ctermbg=none ctermfg=167
    highlight DiffChange        cterm=bold ctermbg=none ctermfg=227

    " highlight signs in Sy

    highlight SignifySignAdd    cterm=bold ctermbg=237  ctermfg=119
    highlight SignifySignDelete cterm=bold ctermbg=237  ctermfg=167
    highlight SignifySignChange cterm=bold ctermbg=237  ctermfg=227
<
For Unix people there is a small script, showcolors.bash, in the repo that
shows all 256 colors available to the terminal. That makes picking the right
numbers much easier.
