--- *mini.notify* Show notifications
---
--- MIT License Copyright (c) 2024 Evgeni Chasnovski
--- Features:
---
--- - Show one or more highlighted notifications in a single floating window.
---
--- - Manage notifications (add, update, remove, clear).
---
--- - Custom |vim.notify()| implementation. To adjust, use |MiniNotify.make_notify()|
--- or save-restore `vim.notify` manually after calling |MiniNotify.setup()|.
---
--- - Automated show of LSP progress report.
---
--- - Track history which can be accessed with |MiniNotify.get_all()|
--- and shown with |MiniNotify.show_history()|.
---
--- # Setup ~
---
--- This module needs a setup with `require('mini.notify').setup({})` (replace
--- `{}` with your `config` table). It will create global Lua table `MiniNotify`
--- which you can use for scripting or manually (with `:lua MiniNotify.*`).
---
--- See |MiniNotify.config| for `config` structure and default values.
---
--- You can override runtime config settings locally to buffer inside
--- `vim.b.mininotify_config` which should have same structure as
--- `MiniNotify.config`. See |mini.nvim-buffer-local-config| for more details.
---
--- # Comparisons ~
---
--- - [j-hui/fidget.nvim](https://github.com/j-hui/fidget.nvim):
--- - Basic goals of providing interface for notifications are similar.
--- - Has more configuration options and visual effects, while this module
--- does not (by design).
---
--- - [rcarriga/nvim-notify](https://github.com/rcarriga/nvim-notify):
--- - Similar to 'j-hui/fidget.nvim'.
---
--- # Highlight groups ~
---
--- - `MiniNotifyBorder` - window border.
--- - `MiniNotifyLspProgress` - notifications from built-in LSP progress report.
--- - `MiniNotifyNormal` - basic foreground/background highlighting.
--- - `MiniNotifyTitle` - window title.
---
--- To change any highlight group, set it directly with |nvim_set_hl()|.
---
--- NOTE: |vim.notify()| override after |MiniNotify.make_notify()| uses own
--- highlight groups per notification level.
---
--- # Disabling ~
---
--- To disable showing notifications, set `vim.g.mininotify_disable` (globally) or
--- `vim.b.mininotify_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.
---@tag MiniNotify
--- # Notification specification ~
---
--- Notification is a table with the following keys:
---
--- - <msg> `(string)` - single string with notification message.
--- Use `\n` to delimit several lines.
--- - <level> `(string)` - notification level as key of |vim.log.levels|.
--- Like "ERROR", "WARN", "INFO", etc.
--- - <hl_group> `(string)` - highlight group with which notification is shown.
--- - <data> `(table)` - extra data to store in notification (like `source`, etc.).
--- - <ts_add> `(number)` - timestamp of when notification is added.
--- - <ts_update> `(number)` - timestamp of the latest notification update.
--- - <ts_remove> `(number|nil)` - timestamp of when notification is removed.
--- It is `nil` if notification was never removed and thus considered "active".
---
--- Notes:
--- - Timestamps are compatible with |strftime()| and have fractional part.

-- Module definition ==========================================================
local MiniNotify = {}
local H = {}
--- Module setup
---
--- This will also:
--- - Set |vim.notify()| custom implementation (see |MiniNotify.make_notify()|).
--- - Clean the history. Use `MiniNotify.setup(MiniNotify.config)` to force
--- clean history while preserving the config.
---
---@param config table|nil Module config table. See |MiniNotify.config|.
---
---@usage >lua
--- require('mini.notify').setup() -- use default config
--- -- OR
--- require('mini.notify').setup({}) -- replace {} with your config table
--- <
MiniNotify.setup = function(config)
-- Export module
_G.MiniNotify = MiniNotify
-- Setup config
config = H.setup_config(config)
-- Apply config
H.apply_config(config)
-- Define behavior
H.create_autocommands()
-- Create default highlighting
H.create_default_hl()
-- Set custom implementation

end
--- Defaults ~
---@eval return MiniDoc.afterlines_to_code(MiniDoc.current.eval_section)
---@text # Content ~
---
--- `config.content` defines how notifications are shown.
---
--- `content.format` is a function which takes single notification object
--- (see |MiniNotify-specification|) and returns a string to be used directly
--- when showing notification.
--- Default: `nil` for |MiniNotify.default_format()|.
---
--- `content.
8000
sort` is a function which takes array of notification objects
--- (see |MiniNotify-specification|) and returns an array of such objects.
--- It can be used to define custom order and/or filter for notifications which
--- are shown simultaneously.
--- Note: Input contains notifications before applying `content.format`.
--- Default: `nil` for |MiniNotify.default_sort()|.
---
--- Example: >lua
---
--- require('mini.notify').setup({
--- content = {
--- -- Use notification message as is for LSP progress
--- format = function(notif)
--- if notif.data.source == 'lsp_progress' then return notif.msg end
--- return MiniNotify.default_format(notif)
--- end,
---
--- -- Show more recent notifications first
--- sort = function(notif_arr)
--- table.sort(
--- notif_arr,
--- function(a, b) return a.ts_update > b.ts_update end
--- )
--- return notif_arr
--- end,
--- },
--- })
--- <
--- # LSP progress ~
---
--- `config.lsp_progress` defines automated notifications for LSP progress.
--- It is implemented as a single updating notification per progress with all
--- information about it.
--- Setting up is done inside |MiniNotify.setup()| via |vim.schedule()|'ed setting
--- of |lsp-handler| for "$/progress" method.
---
--- `lsp_progress.enable` is a boolean indicating whether LSP progress should
--- be shown in notifications. Can be disabled in current session.
--- Default: `true`. Note: Should be `true` during |MiniNotify.setup()| call to be able
--- to enable it in current session.
---
--- `lsp_progress.level` is a level to be used in |MiniNotify.add()|.
--- Default: `'INFO'`.
---
--- `lsp_progress.duration_last` is a number of milliseconds for the last progress
--- report to be shown on screen before removing it.
--- Default: 1000.
---
--- Notes:
--- - This respects previously set handler by saving and calling it.
--- - Overriding "$/progress" method of `vim.lsp.handlers` disables notifications.
--- - All LSP progress notifications set the following fields in `data`:
--- - <source> is `"lsp_progress"`.
--- - <client_name> is set to client's name (provided by client or inferred).
--- - <context> is the latest LSP request context (`ctx` arg of |lsp-handler|).
--- - <response> is the latest LSP response (`result` arg of |lsp-handler|).
---
--- # Window ~
---
--- `config.window` defines behavior of notification window.
---
--- `window.config` is a table defining floating window characteristics
--- or a callable returning such table (will be called with identifier of
--- window's buffer already showing notifications). It should have the same
--- structure as in |nvim_open_win()|. It has the following default values
--- which show notifications in the upper right corner with upper limit on width:
--- - `width` is chosen to fit buffer content but at most `window.max_width_share`
--- share of 'columns'.
--- To have higher maximum width, use function in `config.window` which computes
--- dimensions inside of it (based on buffer content).
--- - `height` is chosen to fit buffer content with enabled 'wrap' (assuming
--- default value of `width`).
--- - `anchor`, `col`, and `row` are "NE", 'columns', and 0 or 1 (depending on tabline).
--- - `border` is "single".
--- - `zindex` is 999 to be as much on top as reasonably possible.
---
--- `window.max_width_share` defines maximum window width as a share of 'columns'.
--- Should be a number between 0 (not included) and 1.
--- Default: 0.382.
---
--- Example for showing notifications in bottom right corner: >lua
---
--- local win_config = function()
--- local has_statusline = vim.o.laststatus > 0
--- local pad = vim.o.cmdheight + (has_statusline and 1 or 0)
--- return { anchor = 'SE', col = vim.o.columns, row = vim.o.lines - pad }
--- end
--- require('mini.notify').setup({ window = { config = win_config } })
--- <
--- `window.winblend` defines 'winblend' value for notification window.
--- Default: 25.
MiniNotify.config = {
-- Content management
content = {
-- Function which formats the notification message
-- By default prepends message with notification time
format = nil,
-- Function which orders notification array from most to least important
-- By default orders first by level and then by update timestamp

--- Make vim.notify wrapper
---
--- Calling this function creates an implementation of |vim.notify()| powered by
--- this module. General idea is to show notification as soon as safely possible
--- (see |vim.schedule_wrap()|) and remove it after a configurable amount of time.
---
--- All notifications set `source = "vim.notify"` in their `data` field.
---
--- This is used with default options inside |MiniNotify.setup()|. To adjust,
--- call manually after `setup()`. For example, to show errors longer: >lua
---
--- require('mini.notify').setup()
--- vim.notify = MiniNotify.make_notify({ ERROR = { duration = 10000 } })
--- <
--- To preserve original `vim.notify`: >lua
---
--- local notify_orig = vim.notify
--- require('mini.notify').setup()
--- vim.notify = notify_orig
--- <
---@param opts table|nil Options to configure behavior of notification `level`
--- (as in |MiniNotify.add()|). Fields are the same as names of `vim.log.levels`
--- with values being tables with possible fields:
--- - <duration> `(number)` - duration (in ms) of how much a notification
--- should be shown. If 0 or negative, notification is not shown at all.
--- - <hl_group> `(string)` - highlight group of notification.
--- Only data different to default can be supplied.
