-- Documentation ==============================================================

--- Minimal and fast statusline with opinionated default look.

---

--- Features:

--- - Define own custom statusline structure for active and inactive windows.

--- This is done with a function which should return string appropriate for

--- |statusline|. Its code should be similar to default one with structure:

--- - Compute string data for every section you want to be displayed.

--- - Combine them in groups with |MiniStatusline.combine_groups()|.

--- - Built-in active mode indicator with colors.

--- - Sections can hide information when window is too narrow (specific window

--- width is configurable per section).

---

--- # Dependencies~

---

--- Suggested dependencies (provide extra functionality, statusline will work

--- without them):

--- - Nerd font (to support extra icons).

--- - Plugin 'lewis6991/gitsigns.nvim' for Git information in

--- |MiniStatusline.section_git|. If missing, no section will be shown.

--- - Plugin 'nvim-tree/nvim-web-devicons' for filetype icons in

--- `MiniStatusline.section_fileinfo`. If missing, no icons will be shown.

---

--- # Setup~

---

--- This module needs a setup with `require('mini.statusline').setup({})`

--- (replace `{}` with your `config` table). It will create global Lua table

--- `MiniStatusline` which you can use for scripting or manually (with

--- `:lua MiniStatusline.*`).

---

--- See |MiniStatusline.config| for `config` structure and default values. For

--- some content examples, see |MiniStatusline-example-content|.

---

--- You can override runtime config settings locally to buffer inside

--- `vim.b.ministatusline_config` which should have same structure as

--- `MiniStatusline.config`. See |mini.nvim-buffer-local-config| for more details.

---

--- # Highlight groups~

---

--- Highlight depending on mode (second output from |MiniStatusline.section_mode|):

--- * `MiniStatuslineModeNormal` - Normal mode.

--- * `MiniStatuslineModeInsert` - Insert mode.

--- * `MiniStatuslineModeVisual` - Visual mode.

--- * `MiniStatuslineModeReplace` - Replace mode.

--- * `MiniStatuslineModeCommand` - Command mode.

--- * `MiniStatuslineModeOther` - other modes (like Terminal, etc.).

---

--- Highlight used in default statusline:

--- * `MiniStatuslineDevinfo` - for "dev info" group

--- (|MiniStatusline.section_git| and |MiniStatusline.section_diagnostics|).

--- * `MiniStatuslineFilename` - for |MiniStatusline.section_filename| section.

--- * `MiniStatuslineFileinfo` - for |MiniStatusline.section_fileinfo| section.

---

--- Other groups:

--- * `MiniStatuslineInactive` - highliting in not focused window.

---

--- To change any highlight group, modify it directly with |:highlight|.

---

--- # Disabling~

---

--- To disable (show empty statusline), set `g:ministatusline_disable`

--- (globally) or `b:ministatusline_disable` (for a buffer) to `v: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.

---@tag mini.statusline

---@tag MiniStatusline

--- Example content

---

--- # Default content~

---

--- This function is used as default value for active content:

--- >

--- function()

--- local mode, mode_hl = MiniStatusline.section_mode({ trunc_width = 120 })

--- local git = MiniStatusline.section_git({ trunc_width = 75 })

--- local diagnostics = MiniStatusline.section_diagnostics({ trunc_width = 75 })

--- local filename = MiniStatusline.section_filename({ trunc_width = 140 })

--- local fileinfo = MiniStatusline.section_fileinfo({ trunc_width = 120 })

--- local location = MiniStatusline.section_location({ trunc_width = 75 })

---

--- return MiniStatusline.combine_groups({

--- { hl = mode_hl, strings = { mode } },

--- { hl = 'MiniStatuslineDevinfo', strings = { git, diagnostics } },

--- '%<', -- Mark general truncate point

--- { hl = 'MiniStatuslineFilename', strings = { filename } },

--- '%=', -- End left alignment

--- { hl = 'MiniStatuslineFileinfo', strings = { fileinfo } },

--- { hl = mode_hl, strings = { location } },

--- })

--- end

--- <

--- # Show boolean options~

---

--- To compute section string for boolean option use variation of this code

--- snippet inside content function (you can modify option itself, truncation

--- width, short and long displayed names):

--- >

--- local spell = vim.wo.spell and (MiniStatusline.is_truncated(120) and 'S' or 'SPELL') or ''

--- <

--- Here `x and y or z` is a common Lua way of doing ternary operator: if `x`

--- is `true`-ish then return `y`, if not - return `z`.

---@tag MiniStatusline-example-content

---@alias __args table Section arguments.

---@alias __section string Section string.

-- Content of statusline as functions which return statusline string. See

-- `:h statusline` and code of default contents (used instead of `nil`).

end

--- Combine groups of sections

---

--- Each group can be either a string or a table with fields `hl` (group's

--- highlight group) and `strings` (strings representing sections).

---

--- General idea of this function is as follows;

--- - String group is used as is (useful for special strings like `%<` or `%=`).

--- - Each table group has own highlighting in `hl` field (if missing, the

--- previous one is used) and string parts in `strings` field. Non-empty

--- strings from `strings` are separated by one space. Non-empty groups are

--- separated by two spaces (one for each highlighting).

---

---@param groups string|table Array of groups.

---

---@return string String suitable for 'statusline'.

MiniStatusline.combine_groups = function(groups)

local parts = vim.tbl_map(function(s)

--stylua: ignore start

if type(s) == 'string' then return s end

if type(s) ~= 'table' then return '' end

local string_arr = vim.tbl_filter(function(x) return type(x) == 'string' and x ~= '' end, s.strings or {})

local str = table.concat(string_arr, ' ')

-- Use previous highlight group

if s.hl == nil then

return (' %s '):format(str)

return string.format('%%#%s#', s.hl)

end

return string.format('%%#%s# %s ', s.hl, str)

--stylua: ignore end

end, groups)

return table.concat(parts, '')

end

--- Decide whether to truncate

---

--- This basically computes window width and compares it to `trunc_width`: if

--- window is smaller then truncate; otherwise don't. Don't truncate by

--- default.

---

--- Use this to manually decide if section needs truncation or not.

---

---@param trunc_width number Truncation width. If `nil`, output is `false`.

MiniStatusline.is_truncated = function(trunc_width)
