1. Intro                                                         *signify-intro*

Signify, or just sy for short, is an quite unobtrusive plugin. If there is
information about changes (in form of patch hunks) since the last commit, they
will be shown on the left side in Vim's sign column.

Easy-peasy!


==============================================================================
2. 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:

    - git
    - mercurial
    - darcs
    - bzr
    - subversion
    - cvs
    - rcs
    - fossil

Sign explanation:

    +

A new line was added. The sign is shown on the same line as the new line.

    _1

A line was deleted. The sign is shown on the line above the deleted line. The
second character indicates the number of deleted lines: 1-9, and # for
everything above.

    !

A line was changed. Something was changed, but the amount of lines stayed the
same. The sign is shown on the same line.

    !_

A line was changed and one or more of the lines below were deleted. A
combination of ! and _. The sign is shown on the same line.

    ‾

This is used instead of _ in the special case of the first line being removed.


==============================================================================
3. 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.

============-

    let g:signify_vcs_list = [ 'git', 'hg' ]

Default: ['git', 'hg', 'svn', 'darcs', 'bzr', 'fossil', 'cvs', 'rcs']

This variable 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 VCS will
be checked for, so you are advised to change this variable to your needs.

NOTE: This only happens once the first time signs get updated. Afterwards, the
VCS will be remembered anyway.

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

============-

    let g:signify_mapping_next_hunk = '<leader>gj'
    let g:signify_mapping_prev_hunk = '<leader>gk'

Mapping for jumping to the next or previous hunk.

============-

    let g:signify_mapping_toggle_highlight = '<leader>gh'

Mapping for toggling line highlighting for lines containing changes.

============-

    let g:signify_mapping_toggle = '<leader>gt'

Mapping for toggling the plugin for the current buffer only.

============-

    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.

============-

    let g:signify_sign_overwrite = 1

Overwrite signs set by other plugins by default.

============-

    let g:signify_update_on_bufenter = 0

Update signs when entering a buffer that was modified.

NOTE: This also saves the buffer to disk!

============-

    let g:signify_line_highlight = 0

Enable line highlighting in addition to using signs by default.

============-

    let g:signify_sign_add               = '+'
    let g:signify_sign_change            = '!'
    let g:signify_sign_change_delete     = '!_'
    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.

============-

    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!

============-

    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.

Otherwise 'diff' will be used.

Default: Does not exist.

4. 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

============-

    :SignifyJumpToNextHunk

Jump to the next hunk. There are two mappings available:

Hardcoded mapping:     ]c
Configurable mapping:  <leader>gj

============-

    :SignifyJumpToPrevHunk

Jump to the previous hunk. There are two mappings available:

Hardcoded mapping:     [c
Configurable mapping:  <leader>gk


==============================================================================
5. 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.
