--- *mini.git* Git integration
--- *MiniGit*
---
--- MIT License Copyright (c) 2024 Evgeni Chasnovski
---
--- ==============================================================================
---
--- Features:
---
--- - Automated tracking of Git related data: root path, status, HEAD, etc.
--- Exposes buffer-local variables for convenient use in statusline.
--- See |MiniGit.enable()| and |MiniGit.get_buf_data()| for more information.
---
--- - |:Git| command for executing any `git` call inside file's repository root with
--- deeper current instance integration (show output as notification/buffer,
--- use to edit commit messages, etc.).
---
--- - Helper functions to inspect Git history:
--- - |MiniGit.show_range_history()| shows how certain line range evolved.
--- - |MiniGit.show_diff_source()| shows file state as it was at diff entry.
--- - |MiniGit.show_at_cursor()| shows Git related data depending on context.
---
--- What it doesn't do:
---
--- - Replace fully featured Git client. Rule of thumb: if feature does not rely
--- on a state of current Neovim (opened buffers, etc.), it is out of scope.
--- For more functionality, use either |MiniDiff| or fully featured Git client.
---
--- Sources with more details:
--- - |:Git|
--- - |MiniGit-examples|
--- - |MiniGit.enable()|
--- - |MiniGit.get_buf_data()|
---
--- # Setup ~
---
--- This module needs a setup with `require('mini.git').setup({})` (replace `{}` with
--- your `config` table). It will create global Lua table `MiniGit` which you can use
--- for scripting or manually (with `:lua MiniGit.*`).
---
--- See |MiniGit.config| for `config` structure and default values.
---
--- # Comparisons ~
---
--- - 'tpope/vim-fugitive':
--- - Mostly a dedicated Git client, while this module is not (by design).
--- - Provides buffer-local Git data only through fixed statusline component,
--- while this module has richer data in the form of a Lua table.
--- - Both provide |:Git| command with 'vim-fugitive' treating some cases
--- extra specially (like `:Git blame`, etc.), while this module mostly
--- treats all cases the same. See |MiniGit-examples| for how they can be
--- manually customized.
--- Also this module provides slightly different (usually richer)
--- completion suggestions.
---
--- - 'NeogitOrg/neogit':
--- - Similar to 'tpope/vim-fugitive', but without `:Git` command.
---
--- - 'lewis6991/gitsigns.nvim':
--- - Provides buffer-local Git data with emphasis on granular diff status,
--- while this module is more oriented towards repository and file level
--- data (root, HEAD, file status, etc.). Use |MiniDiff| for diff tracking.
---
--- # Disabling ~
---
--- To prevent buffer(s) from being tracked, set `vim.g.minigit_disable` (globally)
--- or `vim.b.minigit_disable` (for a buffer) to `true`. Considering high number of
--- different scenarios and customization intentions, writing exact rules for
--- disabling module's functionality is left to user.
--- See |mini.nvim-disabling-recipes| for common recipes.
--- # Statusline component ~
---
--- Tracked buffer data can be used in statusline via `vim.b.minigit_summary_string`
--- buffer-local variable. It is expected to be used as is. To show another info,
--- tweak buffer-local variable directly inside `MiniGitUpdated` `User` event: >lua
---
--- -- Use only HEAD name as summary string
--- local format_summary = function(data)
--- -- Utilize buffer-local table summary
--- local summary = vim.b[data.buf].minigit_summary
--- vim.b[data.buf].minigit_summary_string = summary.head_name or ''
--- end
---
--- local au_opts = { pattern = 'MiniGitUpdated', callback = format_summary }
--- vim.api.nvim_create_autocmd('User', au_opts)
--- <
--- # Tweaking command output ~
---
--- Buffer output of |:Git| command can be tweaked inside autocommand for
--- `MiniGitCommandSplit` `User` event (see |MiniGit-command-events|).
--- For example, to make `:vertical Git blame -- %` align blame output with the
--- current window state, use the following code: >lua
---
--- local align_blame = function(au_data)
--- if au_data.data.git_subcommand ~= 'blame' then return end
---
--- -- Align blame output with source
--- local win_src = au_data.data.win_source
--- vim.wo.wrap = false
--- vim.fn.winrestview({ topline = vim.fn.line('w0', win_src) })
--- vim.api.nvim_win_set_cursor(0, { vim.fn.line('.', win_src), 0 })
---
--- -- Bind both windows so that they scroll together
--- vim.wo[win_src].scrollbind, vim.wo.scrollbind = true, true
--- end
---
--- local au_opts = { pattern = 'MiniGitCommandSplit', callback = align_blame }
--- vim.api.nvim_create_autocmd('User', au_opts)
--- <
--- # History navigation ~
---
--- Function |MiniGit.show_at_cursor()| is specifically exported to make Git
--- history navigation easier. Here are some different ways it can be used:
---
--- - Call inside buffer for already committed file to show the evolution of
--- the current line (or visually selected range) through history.
--- It is essentially a `:Git log HEAD` with proper `-L` flag.
--- This also works inside output of |MiniGit.show_diff_source()|.
---
--- - Call with cursor on commit hash to inspect that commit in full.
--- This is usually helpful in the output of `:Git log`.
---
--- - Call with cursor inside diff entry to inspect its file in the state how it
--- was at certain commit. By default it shows state after commit, unless cursor
--- is on the "deleted" line (i.e. line starting with "-") in which case
--- state before commit is shown.
---
--- This workflow can be made more interactive when used with mapping, like this: >lua
---
--- local rhs = '<Cmd>lua MiniGit.show_at_cursor()<CR>'
--- vim.keymap.set({ 'n', 'x' }, '<Leader>gs', rhs, { desc = 'Show at cursor' })
--- <
---@tag MiniGit-examples
--- The `:Git` user command runs `git` CLI call with extra integration for currently
--- opened Neovim process:
--- - Command is executed inside repository root of the currently active file
--- (or |current-directory| if file is not tracked by this module).
---
--- - Command output is shown either in dedicated buffer in window split or as
--- notification via |vim.notify()|. Which method is used depends on whether
--- particular Git subcommand is supposed to show data for user to inspect
--- (like `log`, `status`, etc.) or not (like `commit`, `push`, etc.). This is
--- determined automatically based on the data Git itself provides.
--- Split window is made current after command execution.
---
--- Use split-related |command-modifiers| (|:vertical|, |:horizontal|, or |:tab|)
--- to force output in a particular type of split. Default split direction is
--- controlled by `command.split` in |MiniGit.config|.
---
--- Use |:silent| command modifier to not show any output.
---
--- Errors and warnings are always shown as notifications.
---
--- See |MiniGit-examples| for the example of tweaking command output.
---
--- - Editor for tasks that require interactive user input (like `:Git commit` or
--- `:Git rebase --interactive`) is opened inside current session in a separate
--- split. Make modifications as in regular buffer, |:write| changes followed by
--- |:close| / |:quit| for Git CLI command to resume.
---
--- Examples of usage:
--- - `:Git log --oneline` - show compact log of current repository.
--- - `:vert Git blame -- %` - show latest commits per line in vertical split.
--- - `:Git help rebase` - show help page for `rebase` subcommand.
--- - `:Git -C <cwd> status` - execute `git status` inside |current-directory|.
---
--- There is also a context aware completion which can be invoked with `<Tab>`:
--- - If completed word starts with "-", options for the current Git subcommand
--- are shown. Like completion at `:Git log -` will suggest `-L`, `--oneline`, etc.
--- - If there is an explicit " -- " to the cursor's left, incremental path
--- suggestions will be shown.
--- - If there is no recognized Git subcommand yet, show list of subcommands.
--- Otherwise for some common subcommands list of its targets will be suggested:
--- like for `:Git branch` it will be list of branches, etc.
---
--- Notes:
--- - Paths are always treated as relative to command's execution directory
--- (file's repository root or |current-directory| if absent).
--- - Don't use quotes for entries containing space, escape it with `\` directly.
--- Like `:Git commit -m Hello\ world` and not `:Git commit -m 'Hello world'`
--- (which treats `'Hello` and `world'` as separate arguments).
---
--- *MiniGit-command-events*
--- There are several `User` events triggered during command execution:
---
--- - `MiniGitCommandDone` - after command is done executing. For Lua callbacks it
--- provides a special `data` table with the following fields:
--- - <cmd_input> `(table)` - structured data about executed command.
--- Has same structure as Lua function input in |nvim_create_user_command()|.
--- - <cwd> `(string)` - directory path inside which Git command was executed.
--- - `<exit_code>` `(number)` - exit code of CLI process.
--- - `<git_command>` `(table)` - array with arguments of full executed command.
--- - `<git_subcommand>` `(string)` - detected Git subcommand (like "log", etc.).
--- - `<stderr>` `(string)` - `stderr` process output.
--- - `<stdout>` `(string)` - `stdout` process output.
---
--- - `MiniGitCommandSplit` - after command showed its output in a split. Triggered
--- after `MiniGitCommandDone` and provides similar `data` table with extra fields:
--- - `<win_source>` `(number)` - window identifier of "source" window (current at
--- the moment before command execution).
--- - `<win_stdout>` `(number)` - window identifier of command output.
---@tag MiniGit-command
---@tag :Git
---@alias __git_buf_id number Target buffer identifier. Default: 0 for current buffer.
---@alias __git_split_field <split> `(string)` - split direction. One of "horizontal", "vertical",
--- "tab", or "auto" (default). Value "auto" uses |:vertical| if only 'mini.git'
--- buffers are shown in the tabpage and |:tab| otherwise.

--- Enable Git tracking in a file buffer
---
--- Tracking is done by reacting to changes in file content or file's repository
--- in the form of keeping buffer data up to date. The data can be used via:
--- - |MiniGit.get_buf_data()|. See its help for a list of actually tracked data.
--- - `vim.b.minigit_summary` (table) and `vim.b.minigit_summary_string` (string)
--- buffer-local variables which are more suitable for statusline.
--- `vim.b.minigit_summary_string` contains information about HEAD, file status,
--- and in progress action (see |MiniGit.get_buf_data()| for more details).
--- See |MiniGit-examples| for how it can be tweaked and used in statusline.
---
--- Note: this function is called automatically for all new normal buffers.
--- Use it explicitly if buffer was disabled.
---
