Detailed descriptions and default values:~

                                                                *'g:ctrlp_map'*
Use this option to change the mapping to invoke CtrlP in |Normal| mode: >
  let g:ctrlp_map = '<c-p>'
<

                                                                *'g:ctrlp_cmd'*
Set the default opening command to use when pressing the above mapping: >
  let g:ctrlp_cmd = 'CtrlP'
<

                                                             *'g:loaded_ctrlp'*
Use this to disable the plugin completely: >
  let g:loaded_ctrlp = 1
<

                                                        *'g:ctrlp_by_filename'*
Set this to 1 to set searching by filename (as opposed to full path) as the
default: >
  let g:ctrlp_by_filename = 0
<
Can be toggled on/off by pressing <c-d> inside the prompt.

                                                             *'g:ctrlp_regexp'*
Set this to 1 to set regexp search as the default: >
  let g:ctrlp_regexp = 0
<
Can be toggled on/off by pressing <c-r> inside the prompt.

                                                *'g:ctrlp_match_window_bottom'*
Set this to 0 to show the match window at the top of the screen: >
  let g:ctrlp_match_window_bottom = 1
<

                                              *'g:ctrlp_match_window_reversed'*
Change the listing order of the files in the match window. The default setting
(1) is from bottom to top: >
  let g:ctrlp_match_window_reversed = 1
<

                                                         *'g:ctrlp_max_height'*
Set the maximum height of the match window: >
  let g:ctrlp_max_height = 10
<

                                                      *'g:ctrlp_switch_buffer'*
When opening a file with <cr> or <c-t>, if the file’s already opened somewhere
CtrlP will try to jump to it instead of opening a new instance: >
  let g:ctrlp_switch_buffer = 2
<
  1 - only jump to the buffer if it’s opened in the current tab.
  2 - jump tab as well if the buffer’s opened in another tab.
  0 - disable this feature.

                                                       *'g:ctrlp_reuse_window'*
When opening a file with <cr>, CtrlP avoids opening it in windows created by
plugins, help and quickfix. Use this to setup some exceptions: >
  let g:ctrlp_reuse_window = 'netrw'
<
Acceptable values are partial name, filetype or buftype of the special buffers.
Use regexp to specify the pattern.
Example: >
  let g:ctrlp_reuse_window = 'netrw\|help\|quickfix'
<

                                                  *'g:ctrlp_working_path_mode'*
When starting up, CtrlP sets its local working directory according to this
variable: >
  let g:ctrlp_working_path_mode = 2
<
  1 - the parent directory of the current file.
  2 - the nearest ancestor that contains one of these directories or files:
      .git/ .hg/ .svn/ .bzr/ _darcs/
  0 - don’t manage working directory.
Note: you can use b:ctrlp_working_path_mode (a |b:var|) to set this option on a
per buffer basis.

                                                       *'g:ctrlp_root_markers'*
Use this to set your own root markers in addition to the default ones (.git/,
.hg/, .svn/, .bzr/, and _darcs/). Your markers will take precedence: >
  let g:ctrlp_root_markers = ['']
<

                                                        *'g:ctrlp_use_caching'*
Set this to 0 to disable per-session caching. When disabled, caching will still
be enabled for directories that have more than 4000 files: >
  let g:ctrlp_use_caching = 1
<
Note: you can quickly purge the cache by pressing <F5> while inside CtrlP.

                                                *'g:ctrlp_clear_cache_on_exit'*
Set this to 0 to enable cross-session caching by not deleting the cache files
upon exiting Vim: >
  let g:ctrlp_clear_cache_on_exit = 1
<

                                                          *'g:ctrlp_cache_dir'*
Set the directory to store the cache files: >
  let g:ctrlp_cache_dir = $HOME.'/.cache/ctrlp'
<

                                                           *'g:ctrlp_dotfiles'*
Set this to 0 if you don’t want CtrlP to scan for dotfiles and dotdirs: >
  let g:ctrlp_dotfiles = 1
<
You can use |'wildignore'| to exclude anything from the search.
Examples: >
  " Excluding version control directories
  set wildignore+=*/.git/*,*/.hg/*,*/.svn/*  " Linux/MacOSX
  set wildignore+=.git\*,.hg\*,.svn\*        " Windows
<
Note #1: the `*/` in front of each directory glob is required.

Note #2: |wildignore| influences the result of |expand()|, |globpath()| and
|glob()| which many plugins use to find stuff on the system (e.g. VCS related
plugins look for .git/, .hg/,... some other plugins look for external *.exe
tools on Windows). So be a little mindful of what you put in your |wildignore|.

                                                      *'g:ctrlp_custom_ignore'*
In addition to |'wildignore'|, use this for files and directories you want only
CtrlP to not show. Use regexp to specify the patterns: >
  let g:ctrlp_custom_ignore = ''
<
Examples: >
  let g:ctrlp_custom_ignore = '\.git$\|\.hg$\|\.svn$'
  let g:ctrlp_custom_ignore = {
    \ 'dir':  '\.git$\|\.hg$\|\.svn$',
    \ 'file': '\.exe$\|\.so$\|\.dll$',
    \ 'link': 'SOME_BAD_SYMBOLIC_LINKS',
    \ }
<
Note: ignoring only works when |globpath()| is used to scan for files.

                                                          *'g:ctrlp_max_files'*
The maximum number of files to scan, set to 0 for no limit: >
  let g:ctrlp_max_files = 10000
<

                                                          *'g:ctrlp_max_depth'*
The maximum depth of a directory tree to recurse into: >
  let g:ctrlp_max_depth = 40
<
Note: the larger these values, the more memory Vim uses.

                                                       *'g:ctrlp_user_command'*
Specify an external tool to use for listing files instead of using Vim’s
|globpath()|. Use %s in place of the target directory: >
  let g:ctrlp_user_command = ''
<
Examples: >
  let g:ctrlp_user_command = 'find %s -type f'       " MacOSX/Linux
  let g:ctrlp_user_command = 'dir %s /-n /b /s /a-d' " Windows
<
You can also use 'grep', 'findstr' or something else to filter the results.
Examples: >
  let g:ctrlp_user_command = 'find %s -type f | grep (?!tmp/.*)'
  let g:ctrlp_user_command = 'dir %s /-n /b /s /a-d | findstr .*\.py$'
<
Use a version control listing command when inside a repository, this is faster
when scanning large projects: >
  let g:ctrlp_user_command = [root_marker, listing_command, fallback_command]
  let g:ctrlp_user_command = {
    \ 'types': {
      \ 1: [root_marker_1, listing_command_1],
      \ n: [root_marker_n, listing_command_n],
      \ },
    \ 'fallback': fallback_command
    \ }
<
Examples: >
  let g:ctrlp_user_command = ['.git/', 'cd %s && git ls-files']
  let g:ctrlp_user_command = ['.hg/', 'hg --cwd %s locate -I .']
  let g:ctrlp_user_command = {
    \ 'types': {
      \ 1: ['.git/', 'cd %s && git ls-files'],
      \ 2: ['.hg/', 'hg --cwd %s locate -I .'],
      \ },
    \ 'fallback': 'find %s -type f'
    \ }
<
If the fallback_command is empty or not defined, |globpath()| will then be used
when searching outside a repo.

                                                        *'g:ctrlp_max_history'*
The maximum number of input strings you want CtrlP to remember. The default
value mirrors Vim’s global |'history'| option: >
  let g:ctrlp_max_history = &history
<
Set to 0 to disable prompt’s history. Browse the history with <c-n> and <c-p>.

                                                      *'g:ctrlp_open_new_file'*
Use this option to specify how the newly created file is to be opened when
pressing <c-y>:
  t - in a new tab
  h - in a new horizontal split
  v - in a new vertical split
  r - in the current window
>
  let g:ctrlp_open_new_file = 'v'
<

                                                *'g:ctrlp_open_multiple_files'*
If non-zero, this will enable opening multiple files with <c-z> and <c-o>: >
  let g:ctrlp_open_multiple_files = 'v'
<
Example: >
  let g:ctrlp_open_multiple_files = '2vr'
<
For the number:
  - If given, it’ll be used as the maximum number of windows or tabs to create
    when opening the files (the rest will be opened as hidden buffers).
  - If not given, <c-o> will open all files, each in a new window or new tab.
For the letters:
  t - each file in a new tab.
  h - each file in a new horizontal split.
  v - each file in a new vertical split.
  Reuse the current window:
  tr,
  hr,
  vr - open the first file in the current window, then the remaining files in
       new splits or new tabs just like with t, h, v.

                                                            *'g:ctrlp_arg_map'*
When this is set to 1, the <c-o> and <c-y> mappings will accept one extra key
as an argument to override their default behavior: >
  let g:ctrlp_arg_map = 0
<
Pressing <c-o> or <c-y> will then prompt for a keypress. The key can be:
  t - open in tab(s)
  h - open in horizontal split(s)
  v - open in vertical split(s)
  r - open in current window (for <c-y> only)
  <esc>, <c-c> - cancel and go back to the prompt.
  Any other key - use the behavior specified with |g:ctrlp_open_new_file| and
  |g:ctrlp_open_multiple_files|.

                                                    *'g:ctrlp_follow_symlinks'*
Set this to 1 to follow symbolic links when listing files: >
  let g:ctrlp_follow_symlinks = 0
<
When enabled, looped internal symlinks will be ignored to avoid duplicates.

                                                        *'g:ctrlp_lazy_update'*
Set this to 1 to enable the lazy-update feature: only update the match window
after typing’s been stopped for a certain amount of time: >
  let g:ctrlp_lazy_update = 0
<
If is 1, update after 250ms. If bigger than 1, the number will be used as the
delay time in milliseconds.

                                                      *'g:ctrlp_default_input'*
Set this to 1 to enable seeding the prompt with the current file’s relative
path: >
  let g:ctrlp_default_input = 0
<

                                                         *'g:ctrlp_use_migemo'*
Set this to 1 to use Migemo Pattern for Japanese filenames. Migemo Search only
works in regexp mode. To split the pattern, separate words with space: >
  let g:ctrlp_use_migemo = 0
<

                                                    *'g:ctrlp_prompt_mappings'*
Use this to customize the mappings inside CtrlP’s prompt to your liking. You
only need to keep the lines that you’ve changed the values (inside []): >
  let g:ctrlp_prompt_mappings = {
    \ 'PrtBS()':              ['<bs>', '<c-]>'],
    \ 'PrtDelete()':          ['<del>'],

    \ 'PrtInsert("w")':       ['<F2>', '<insert>'],
    \ 'PrtInsert("s")':       ['<F3>'],

    \ 'PrtExit()':            ['<esc>', '<c-c>', '<c-g>'],
    \ }
<
Note: In some terminals, it’s not possible to remap <c-h> without also changing
<bs> (|keycodes|). So if pressing <bs> moves the cursor to the left instead of
deleting a char for you, add this to your |.vimrc| to disable the plugin’s
default <c-h> mapping: >
  let g:ctrlp_prompt_mappings = { 'PrtCurLeft()': ['<left>', '<c-^>'] }

  a-z
  0-9
  ~^-=;`',.+!@#$%&_(){}[]
    Cycle through the lines with the first letter (of paths or filenames) that
    matches that key.

===============================================================================
INPUT FORMATS                                             *ctrlp-input-formats*

Formats for inputting in the prompt:~

a)  Simple string.

    E.g. 'abc' is understood internally as 'a[^a]\{-}b[^b]\{-}c'

b)  When in regexp mode, the input string’s treated as a Vim’s regexp |pattern|
    without any modification.

    E.g. 'abc\d*efg' will be read as 'abc\d*efg'.

    See |ctrlp-fullregexp| (keymap) and |g:ctrlp_regexp_search| (option) for
    how to enable regexp mode.

c)  End the string with a colon ':' followed by a Vim command to execute that
    command after opening the file. If you need to use ':' literally, escape it
    with a backslash: '\:'. When opening multiple files, the command will be
    executed on each opening file.

    E.g. 'abc:45' will open the selected file and jump to line 45.

         'abc:/any\:string' will open the selected file and jump to the first
         instance of 'any:string'.

         'abc:+setf\ myfiletype|50' will open the selected file and set its
         filetype to 'myfiletype', then jump to line 50.

         'abc:diffthis' will open the selected files and run |:diffthis| on the
         first 4 files (if marked).

    See also Vim’s |++opt| and |+cmd|.

d)  Type exactly two dots '..' at the start of the prompt and press enter to go
    backward in the directory tree by 1 level. If the parent directory is
    large, this might be slow.

e)  Similarly, submit '/' or '\' to find and go to the project’s root. If the
    project is large, using a VCS listing command to look for files might help
    speeding up the intial scan (see |g:ctrlp_user_command| for more details).

    Note: e) and d) only work in find file mode and directory mode.

f)  Type the name of a non-existent file and press <c-y> to create it. Mark a
    file with <c-z> to create the new file in the same directory as the marked
    file.

    E.g. 'parentdir/newfile.txt' will create a directory named 'parentdir' as
         well as 'newfile.txt'.

         If 'some/old/dirs/oldfile.txt' is marked with <c-z>, then 'parentdir'
         and 'newfile.txt' will be created in 'some/old/dirs'. The final path
         will then be 'some/old/dirs/parentdir/newfile.txt'.

         Use '\' in place of '/' on Windows (if |'ssl'| is not set).

g)  Submit ? to open this help file.
