--- *mini.statusline* Statusline
--- *MiniStatusline*
---
--- MIT License Copyright (c) 2021 Evgeni Chasnovski
---
--- ==============================================================================
---
--- 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, will work without them):
---
--- - Nerd font (to support extra icons).
---
--- - Enabled |MiniIcons| module for |MiniStatusline.section_fileinfo()|.
--- Falls back to using 'nvim-tree/nvim-web-devicons' plugin or shows nothing.
---
--- - Enabled |MiniGit| module for |MiniStatusline.section_git()|.
--- Falls back to using 'lewis6991/gitsigns.nvim' plugin or shows nothing.
---
--- - Enabled |MiniDiff| module for |MiniStatusline.section_diff()|.
--- Falls back to using 'lewis6991/gitsigns.nvim' plugin or shows nothing.
---
--- # 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 `vim.g.ministatusline_disable`
--- (globally) or `vim.b.ministatusline_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.
--- Example content
---
--- # Default content ~
---
--- This function is used as default value for active content: >lua
---
--- function()
--- local mode, mode_hl = MiniStatusline.section_mode({ trunc_width = 120 })
--- local git = MiniStatusline.section_git({ trunc_width = 40 })
--- local diff = MiniStatusline.section_diff({ trunc_width = 75 })
--- local diagnostics = MiniStatusline.section_diagnostics({ trunc_width = 75 })
--- local lsp = MiniStatusline.section_lsp({ 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 })
--- local search = MiniStatusline.section_searchcount({ trunc_width = 75 })
---
--- return MiniStatusline.combine_groups({
--- { hl = mode_hl, strings = { mode } },
--- { hl = 'MiniStatuslineDevinfo', strings = { git, diff, diagnostics, lsp } },
--- '%<', -- Mark general truncate point
--- { hl = 'MiniStatuslineFilename', strings = { filename } },
--- '%=', -- End left alignment
--- { hl = 'MiniStatuslineFileinfo', strings = { fileinfo } },
--- { hl = mode_hl, strings = { search, 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): >lua
---
--- 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 __statusline_args table Section arguments.
---@alias __statusline_section string Section string.

--- 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 table Array of groups.
---
---@return string String suitable for 'statusline'.
MiniStatusline.combine_groups = function(groups)

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

if s.hl == nil then return ' ' .. str .. ' ' end
-- Allow using this highlight group later
if str:len() == 0 then return '%#' .. s.hl .. '#' end
return string.format('%%#%s# %s ', s.hl, str)
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|nil Truncation width. If `nil`, output is `false`.
