INTRODUCTION                                                        *gitsigns*

Gitsigns is a plugin for Neovim that provides integration with Git via a
feature set which includes (but not limited to):
  • Provides signs in the |signcolumn| to show changed/added/removed lines.
  • Mappings to operate on hunks to stage, undo or reset against Git's index.

Gitsigns is implemented entirely in Lua which is built into Neovim and
requires no external dependencies other than git. This is unlike other plugins
that require python, node, etc, which need to communicate with Neovim using
|RPC|.  By default, Gitsigns also uses Neovim's built-in diff library
(`vim.diff`) unlike other similar plugins that need to run `git-diff` as an
external process which is less efficient, has tighter bottlenecks and requires
file IO.

USAGE                                                         *gitsigns-usage*

For basic setup with all batteries included:
>
    require('gitsigns').setup()
<

Configuration can be passed to the setup function. Here is an example with most
of the default settings:
>
    require('gitsigns').setup {
      signs = {
        add          = {hl = 'GitSignsAdd'   , text = '│', numhl='GitSignsAddNr'   , linehl='GitSignsAddLn'},
        change       = {hl = 'GitSignsChange', text = '│', numhl='GitSignsChangeNr', linehl='GitSignsChangeLn'},
        delete       = {hl = 'GitSignsDelete', text = '_', numhl='GitSignsDeleteNr', linehl='GitSignsDeleteLn'},
        topdelete    = {hl = 'GitSignsDelete', text = '‾', numhl='GitSignsDeleteNr', linehl='GitSignsDeleteLn'},
        changedelete = {hl = 'GitSignsChange', text = '~', numhl='GitSignsChangeNr', linehl='GitSignsChangeLn'},
      },
      numhl = false,
      linehl = false,
      keymaps = {
        -- Default keymap options
        noremap = true,

        ['n ]c'] = { expr = true, "&diff ? ']c' : '<cmd>lua require\"gitsigns\".next_hunk()<CR>'"},
        ['n [c'] = { expr = true, "&diff ? '[c' : '<cmd>lua require\"gitsigns\".prev_hunk()<CR>'"},

        ['n <leader>hu'] = '<cmd>lua require"gitsigns".undo_stage_hunk()<CR>',
        ['n <leader>hr'] = '<cmd>lua require"gitsigns".reset_hunk()<CR>',
        ['v <leader>hr'] = '<cmd>lua require"gitsigns".reset_hunk({vim.fn.line("."), vim.fn.line("v")})<CR>',
        ['n <leader>hR'] = '<cmd>lua require"gitsigns".reset_buffer()<CR>',

      },
      watch_index = {
        interval = 1000
      },

MAPPINGS                                                   *gitsigns-mappings*

All mappings are configurable via |gitsigns-setup()|.

Most actions can be repeated with `.` if you have |vim-repeat| installed.

Buffer ~
    ]c         Jump to the next hunk.
    [c         Jump to the previous hunk.
    <leader>hs Stage the hunk at the cursor position.
    <leader>hu Undo the last stage hunk.
    <leader>hr Reset the lines of the hunk to what is in Git's index.
    <leader>hp Preview the hunk in a floating window.

Custom mappings are defined using the `keymaps` table in the config table
passed to |gitsigns-setup()|. See |gitsigns-config-keymaps|.

                Stage the hunk at the cursor position, or all hunks in the
                given range. If {range} is provided, all hunks that intersect
                with the given range are staged.

                Attributes: ~
                    {async}

                Parameters:~
                    {range} table|nil List-like table of two integers making
                    up the line range from which you want to stage the hunks.

                Undo the last call of stage_hunk(). Note: only the calls to
                stage_hunk() performed in the current session can be undone.

                Attributes: ~
                    {async}

stage_buffer()                                       *gitsigns.stage_buffer()*
                Stage all hunks in current buffer.

                Unstage all hunks for current buffer in the index. Note:
                Unlike |gitsigns.undo_stage_hunk()| this doesn't simply undo
                stages, this runs an `git reset` on current buffers file.

                Attributes: ~
                    {async}

reset_hunk({range})                                    *gitsigns.reset_hunk()*

                Run git blame on the current line and show the results in a
                floating window. If {full} is true then the full commit
                message is displayed along with the corresponding hunk.

                Attributes: ~
                    {async}

                Change the base revision to diff against. If {base} is not
                given, then the original base is used. If {global} is given
                and true, then change the base revision of all buffers,
                including any new buffers.

                Attributes: ~

CONFIGURATION                                                *gitsigns-config*

This section describes the configuration fields which can be passed to
|gitsigns.setup()|. Note fields of type `table` may be marked with extended
meaning the field is merged with the default, with the user value given higher
precedence. This allows only specific sub-fields to be configured without
having to redefine the whole field.

<
      Configuration for signs:
        • `hl` specifies the highlight group to use for the sign.
        • `text` specifies the character to use for the sign.
        • `numhl` specifies the highlight group to use for the number column
          (see |gitsigns-config.numhl|).
        • `linehl` specifies the highlight group to use for the line
          (see |gitsigns-config.linehl|).
        • `show_count` to enable showing count of hunk, e.g. number of deleted
          lines.

      Note if `hl`, `numhl` or `linehl` use a `GitSigns*` highlight and it is
      not defined, it will be automatically derived by searching for other
      defined highlights in the following order:
        • `GitGutter*`
        • `Signify*`
        • `Diff*Gutter`
        • `diff*`
        • `Diff*`

      For example if `signs.add.hl = GitSignsAdd` and `GitSignsAdd` is not
      defined but `GitGutterAdd` is defined, then `GitSignsAdd` will be linked
      to `GitGutterAdd`.

      Keymaps to set up when attaching to a buffer.

      Each key in the table defines the mode and key (whitespace delimited)
      for the mapping and the value defines what the key maps to. The value
      can be a table which can contain keys matching the options defined in
      |map-arguments| which are: `expr`, `noremap`, `nowait`, `script`,
      `silent`, `unique` and `buffer`.  These options can also be used in
      the top level of the table to define default options for all mappings.

      Since this field is not extended (unlike |gitsigns-config-signs|),
      mappings defined in this field can be disabled by setting the whole field
      to `{}`, and |gitsigns-config-on_attach| can instead be used to define
      mappings.

on_attach                                          *gitsigns-config-on_attach*
      Type: `function`, Default: `nil`

      Callback called when attaching to a buffer. Mainly used to setup keymaps
      when `config.keymaps` is empty. The buffer number is passed as the first
      argument.

      This callback can return `false` to prevent attaching to the buffer.

      Example: >
        on_attach = function(bufnr)
          if vim.api.nvim_buf_get_name(bufnr):match(<PATTERN>) then
            -- Don't attach to specific buffers whose name matches a pattern
            return false
          end

          -- Setup keymaps
          vim.api.nvim_buf_set_keymap(bufnr, 'n', 'hs', '<cmd>lua require"gitsigns".stage_hunk()<CR>', {})
          ... -- More keymaps

      When opening a file, a libuv watcher is placed on the respective
      `.git/index` file to detect when changes happen to use as a trigger to
      update signs.

      Fields: ~
        • `interval`:
            Interval the watcher waits between polls of `.git/index` is milliseconds.

        • `follow_files`:
            If a file is moved with `git mv`, switch the buffer to the new location.

      Type: `boolean`, Default: `false`

      Enable/disable line number highlights.

      When enabled the highlights defined in `signs.*.numhl` are used. If
      the highlight group does not exist, then it is automatically defined
      and linked to the corresponding highlight group in `signs.*.hl`.

linehl                                                *gitsigns-config-linehl*
      Type: `boolean`, Default: `false`

      Enable/disable line highlights.

      When enabled the highlights defined in `signs.*.linehl` are used. If
      the highlight group does not exist, then it is automatically defined
      and linked to the corresponding highlight group in `signs.*.hl`.

            Note Neovim v0.5 uses LuaJIT's FFI interface, whereas v0.5+ uses
            `vim.diff`.
        • indent_heuristic: string
            Use the indent heuristic for the internal
            diff library.

        }
<
      The count characters used when `signs.*.show_count` is enabled. The
      `+` entry is used as a fallback. With the default, any count outside
      of 1-9 uses the `>` character in the sign.

      Possible use cases for this field:
        • to specify unicode characters for the counts instead of 1-9.

:Gitsigns {subcmd} {args}  Run a Gitsigns command. {subcmd} can be any
                           function documented in |gitsigns-functions|.
                           Each argument in {args} will be attempted to be
                           parsed as a Lua value using `loadstring`, however

SPECIFYING OBJECTS                          *gitsigns-object* *gitsigns-revision*

Gitsigns objects are Git revisions as defined in the "SPECIFYING REVISIONS"
section in the gitrevisions(7) man page. For commands that accept an optional
base, the default is the file in the index. Examples:

Object        Meaning ~
@             Version of file in the commit referenced by @ aka HEAD
main          Version of file in the commit referenced by main
main^         Version of file in the parent of the commit referenced by main
main~         "
main~1        "
main...other  Version of file in the merge base of main and other
@^            Version of file in the parent of HEAD
@~2           Version of file in the grandparent of HEAD
92eb3dd       Version of file in the commit 92eb3dd
:1            The file's common ancestor during a conflict
:2            The alternate file in the target branch during a conflict

STATUSLINE                                               *gitsigns-statusline*

                                    *b:gitsigns_status* *b:gitsigns_status_dict*
The buffer variables `b:gitsigns_status` and `b:gitsigns_status_dict` are
provided. `b:gitsigns_status` is formatted using `config.status_formatter`
. `b:gitsigns_status_dict` is a dictionary with the keys:

        • `added` - Number of added lines.
        • `changed` - Number of changed lines.
        • `removed` - Number of removed lines.
        • `head` - Name of current HEAD (branch or short commit hash).
        • `root` - Top level directory of the working tree.
        • `gitdir` - .git directory.

Example:
>

                                            *b:gitsigns_head* *g:gitsigns_head*
Use `g:gitsigns_head` and `b:gitsigns_head` to return the name of the current
HEAD (usually branch name). If the current HEAD is detached then this will be
a short commit hash. `g:gitsigns_head` returns the current HEAD for the
current working directory, whereas `b:gitsigns_head` returns the current HEAD
for each buffer.

                                                  *b:gitsigns_blame_line_dict*
If |gitsigns-config-current_line_blame| is enabled, then contains dictionary
of the blame object for current line. For complete list of keys, see the
{blame_info} argument from |gitsigns-config-current_line_blame_formatter|.

TEXT OBJECTS                                             *gitsigns-textobject*

Since text objects are defined via keymaps, these are exposed and configurable
via the config, see |gitsigns-config-keymaps|. The lua implementation is
exposed through |gitsigns.select_hunk()|.
