--- *mini.extra* Extra 'mini.nvim' functionality
--- *MiniExtra*
---
--- MIT License Copyright (c) 2023 Evgeni Chasnovski
---
--- ==============================================================================
---
--- Extra useful functionality which is not essential enough for other 'mini.nvim'
--- modules to include directly.
---
--- Features:
---
--- - Various pickers for 'mini.pick':
--- - Built-in diagnostic (|MiniExtra.pickers.diagnostic()|).
--- - File explorer (|MiniExtra.pickers.explorer()|).
--- - Git branches/commits/files/hunks (|MiniExtra.pickers.git_hunks()|, etc.).
--- - Command/search/input history (|MiniExtra.pickers.history()|).
--- - LSP references/symbols/etc. (|MiniExtra.pickers.lsp()|).
--- - Tree-sitter nodes (|MiniExtra.pickers.treesitter()|).
--- - And much more.
--- See |MiniExtra.pickers| for more.
---
--- - Various textobject specifications for 'mini.ai'. See |MiniExtra.gen_ai_spec|.
---
--- - Various highlighters for 'mini.hipatterns'. See |MiniExtra.gen_highlighter|.
---
--- Notes:
--- - This module requires only those 'mini.nvim' modules which are needed for
--- a particular functionality: 'mini.pick' for pickers, etc.
---
--- # Setup ~
---
--- This module needs a setup with `require('mini.extra').setup({})` (replace
--- `{}` with your `config` table). It will create global Lua table `MiniExtra`
--- which you can use for scripting or manually (with `:lua MiniExtra.*`).
---
--- See |MiniExtra.config| for `config` structure and default values.
---
--- This module doesn't have runtime options, so using `vim.b.miniextra_config`
--- will have no effect here.
---
--- # Comparisons ~
---
--- - 'nvim-telescope/telescope.nvim':
--- - With |MiniExtra.pickers|, 'mini.pick' is reasonably on par when it comes
--- to built-in pickers.
---
--- - 'ibhagwan/fzf-lua':
--- - Same as 'nvim-telescope/telescope.nvim'.
---@diagnostic disable:undefined-field
---@diagnostic disable:discard-returns
---@diagnostic disable:unused-local
---@diagnostic disable:cast-local-type
---@diagnostic disable:undefined-doc-name
---@diagnostic disable:luadoc-miss-type-name
---@alias __extra_ai_spec_return function Function implementing |MiniAi-textobject-specification|.
---@alias __extra_pickers_local_opts table|nil Options defining behavior of this particular picker.
---@alias __extra_pickers_opts table|nil Options forwarded to |MiniPick.start()|.
---@alias __extra_pickers_return any Output of the called picker.
---@alias __extra_pickers_git_notes Notes:
--- - Requires executable `git`.
--- - Requires target path to be part of git repository.
--- - Present for exploration and navigation purposes. Doing any Git operations
--- is suggested to be done in a dedicated Git client and is not planned.
---@alias __extra_pickers_git_path - <path> `(string|nil)` - target path for Git operation (if required). Also
--- used to find Git repository inside which to construct items.
--- Default: `nil` for root of Git repository containing |current-directory|.
-- Module definition ==========================================================

---
---@param config table|nil Module config table. See |MiniExtra.config|.
---
---@usage >lua

--- <

--- 'mini.ai' textobject specification generators
---
--- This is a table with function elements. Call to actually get specification.
---
--- Assumed to be used as part of |MiniAi.setup()|. Example: >lua
---
--- local gen_ai_spec = require('mini.extra').gen_ai_spec
--- require('mini.ai').setup({
--- custom_textobjects = {
--- B = gen_ai_spec.buffer(),
--- D = gen_ai_spec.diagnostic(),

--- N = gen_ai_spec.number(),
--- },
--- })
--- <
MiniExtra.gen_ai_spec = {}
--- Current buffer textobject
---
--- Notes:
--- - `a` textobject selects all lines in a buffer.
--- - `i` textobject selects all lines except blank lines at start and end.
---
---@return __extra_ai_spec_return
MiniExtra.gen_ai_spec.buffer = function()
return function(ai_type)
local start_line, end_line = 1, vim.fn.line('$')
if ai_type == 'i' then
-- Skip first and last blank lines for `i` textobject
local first_nonblank, last_nonblank = vim.fn.nextnonblank(start_line), vim.fn.prevnonblank(end_line)
-- Do nothing for buffer with all blanks
if first_nonblank == 0 or last_nonblank == 0 then return { from = { line = start_line, col = 1 } } end
start_line, end_line = first_nonblank, last_nonblank
end

return { from = { line = start_line, col = 1 }, to = { line = end_line, col = to_col } }
end
end
--- Current buffer diagnostic textobject
---
--- Notes:
--- - Both `a` and `i` textobjects return |vim.diagnostic.get()| output for the
--- current buffer. It is modified to fit |MiniAi-textobject-specification|.
---
---@param severity any Which severity to use. Forwarded to |vim.diagnostic.get()|.
--- Default: `nil` to use all diagnostic entries.
---
---@return __extra_ai_spec_return
MiniExtra.gen_ai_spec.diagnostic = function(severity)
return function(ai_type)
local cur_diag = vim.diagnostic.get(0, { severity = severity })
local regions = {}
for _, diag in ipairs(cur_diag) do
local from = { line = diag.lnum + 1, col = diag.col + 1 }
local to = { line = diag.end_lnum + 1, col = diag.end_col }
if to.line == nil or to.col == nil then to = { line = diag.lnum + 1, col = diag.col + 1 } end
table.insert(regions, { from = from, to = to })
end
return regions
end
end
--- Current buffer indent scopes textobject
---
--- Indent scope is a set of consecutive lines with the following properties:
--- - Lines above first and below last are non-blank. They are called borders.
--- - There is at least one non-blank line in a set.
--- - All non-blank lines between borders have strictly greater indent
--- (perceived leading space respecting |tabstop|) than either of borders.
---
--- Notes:
--- - `a` textobject selects scope including borders.
--- - `i` textobject selects the scope charwise.
--- - Differences with |MiniIndentscope.textobject|:
--- - This textobject always treats blank lines on top and bottom of `i`
--- textobject as part of it, while 'mini.indentscope' can configure that.
--- - This textobject can select non-covering scopes, while 'mini.indentscope'
--- can not (by design).
--- - In this textobject scope computation is done only by "casting rays" from
--- top to bottom and not in both ways as in 'mini.indentscope'.

--- 'mini.pick' pickers

--- Notes:

--- - All of them are automatically registered in |MiniPick.registry|.
--- - All use default versions of |MiniPick-source.preview|, |MiniPick-source.choose|,
--- and |MiniPick-source.choose_marked| if not stated otherwise.
--- Shown text and |MiniPick-source.show| are targeted to the picked items.
---
--- Examples of usage:

--- - With |:Pick| command: `:Pick buf_lines scope='current'`
--- Note: this requires calling |MiniExtra.setup()|.

--- Neovim history picker
---
--- Pick from output of |:history|.
--- Notes:
--- - Has no preview.
--- - Choosing action depends on scope:
--- - For "cmd" / ":" scopes, the command is executed.
--- - For "search" / "/" / "?" scopes, search is redone.
--- - For other scopes nothing is done (but chosen item is still returned).
---
--- Examples ~
---
--- - Command history: `MiniExtra.pickers.history({ scope = ':' })`
--- - Search history: `:Pick history scope='/'`
---
---@param local_opts __extra_pickers_local_opts
--- Possible fields:
--- - <scope> `(string)` - any allowed {name} flag of |:history| command.
--- Note: word abbreviations are not allowed. Default: "all".
