--- *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'.

--- used to find Git repository inside which to construct items.

---

--- 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

--- })

--- <

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

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

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'.

--- This works in most common scenarios and doesn't work only if indent of

--- of the bottom border is expected to be larger than the top.

---

---@return function Function implementing |MiniAi-textobject-specification|.

--- It returns array of regions representing all indent scopes in the buffer

--- ordered increasingly by the start line.

MiniExtra.gen_ai_spec.indent = function() return H.ai_indent_spec end

--- Current line textobject

---

--- Notes:

--- - `a` textobject selects whole line.

--- - `i` textobject selects line after initial indent.

---

---@return __extra_ai_spec_return

MiniExtra.gen_ai_spec.line = function()

return function(ai_type)

local line_num = vim.fn.line('.')

local line = vim.fn.getline(line_num)

local to_col = line:len()

return { from = { line = line_num, col = from_col }, to = { line = line_num, col = to_col } }

end

end

--- Number textobject

---

--- Notes:

--- - `a` textobject selects a whole number possibly preceded with "-" and

--- possibly followed by decimal part (dot and digits).

--- - `i` textobject selects consecutive digits.

---

---@return __extra_ai_spec_return

MiniExtra.gen_ai_spec.number = function()

-- First find consecutive digits

if from == nil then return nil, nil end

-- Make sure that these digits were not processed before. This can happen

-- because 'miin.ai' does next with `init = from + 1`, meaning that

-- "-12.34" was already matched, then it would try to match starting from

-- "1": we want to avoid matching that right away and avoid matching "34"

-- from this number.

if from == init and line:sub(from - 1, from - 1) == '-' then

init = to + 1

from, to = line:find(digits_pattern, init)

end

--- },

--- })

--- <

MiniExtra.gen_highlighter = {}

--- Highlight words

---

--- Notes:

--- - Words should start and end with alphanumeric symbol (latin letter or digit).

--- - Words will be highlighted only in full and not if part bigger word, i.e.

--- there should not be alphanumeric symbol before and after it.

---

---@param words table Array of words to highlight. Will be matched as is, not

--- as Lua pattern.

---@param group string|function Proper `group` field for `highlighter`.

--- See |MiniHipatterns.config|.

---@param extmark_opts any Proper `extmark_opts` field for `highlighter`.

--- See |MiniHipatterns.config|.

--- 'mini.pick' pickers

---

--- A table with |MiniPick| pickers (which is a hard dependency).

--- Notes:

--- - All have the same signature:

--- - <local_opts> - optional table with options local to picker.

--- - <opts> - optional table with options forwarded to |MiniPick.start()|.

--- - All of them are automatically registered in |MiniPick.registry| inside

--- both |MiniExtra.setup()| or |MiniPick.setup()| (only one is enough).

--- - 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:

--- - As Lua code: `MiniExtra.pickers.buf_lines()`.

--- - With |:Pick| command: `:Pick buf_lines scope='current'`

--- Note: this requires calling |MiniExtra.setup()|.

--- File explorer picker

---

--- Explore file system and open file.

--- Notes:

--- - <cwd> `(string)` - initial directory to explore. Should be a valid

--- - <filter> `(function)` - callable predicate to filter items to show.

--- Will be called for every item and should return `true` if it should be

--- shown. Each item is a table with the following fields:

--- - <fs_type> `(string)` - path type. One of "directory" or "file".

--- - <path> `(string)` - item path.

--- - <text> `(string)` - shown text (path's basename).

--- - <sort> `(function)` - callable item sorter. Will be called with array

--- of items (each element with structure as described above) and should
