--- *mini.files* Navigate and manipulate file system
--- *MiniFiles*
---
--- MIT License Copyright (c) 2023 Evgeni Chasnovski
---
--- ==============================================================================
---
--- Features:
--- - Navigate file system using column view (Miller columns) to display nested
--- directories. See |MiniFiles-navigation| for overview.
---
--- - Opt-in preview of file or directory under cursor.
---
--- - Manipulate files and directories by editing text buffers: create, delete,
--- copy, rename, move. See |MiniFiles-manipulation| for overview.
---
--- - Use as default file explorer instead of |netrw|.
---
--- - Configurable:
--- - Filter/prefix/sort of file system entries.
--- - Mappings used for common explorer actions.
--- - UI options: whether to show preview of file/directory under cursor, etc.
---
--- What it doesn't do:
--- - Try to be replacement of system file explorer. It is mostly designed to
--- be used within Neovim to quickly explore file system structure, open
--- files, and perform some quick file system edits.
---
--- - Work on remote locations. Only local file system is supported.
---
--- - Provide built-in interactive toggle of content `filter` and `sort`.
--- See |MiniFiles-examples| for some common examples.
---
--- - Provide out of the box extra information like git or diagnostic status.
--- This can be achieved by setting |extmarks| on appropriate event(s)
--- (see |MiniFiles-events|)
---
--- Notes:
--- - This module is written and thoroughly tested on Linux. Support for other
--- platform/OS (like Windows or MacOS) is a goal, but there is no guarantee.
---
--- - Works on all supported versions but using Neovim>=0.9 is recommended.
---
--- - This module silently reacts to not enough permissions:
--- - In case of missing file, check its or its parent read permissions.
--- - In case of no manipulation result, check write permissions.
---
--- # Dependencies ~
---
--- Suggested dependencies (provide extra functionality, will work without them):
--- - Plugin 'nvim-tree/nvim-web-devicons' for filetype icons near the entry
--- name. If missing, default icons will be used.
---
--- # Setup ~
---
--- This module needs a setup with `require('mini.files').setup({})` (replace
--- `{}` with your `config` table). It will create global Lua table `MiniFiles`
--- which you can use for scripting or manually (with `:lua MiniFiles.*`).
---
--- See |MiniFiles.config| for available config settings.
---
--- You can override runtime config settings (like mappings or window options)
--- locally to buffer inside `vim.b.minifiles_config` which should have same
--- structure as `MiniFiles.config`. See |mini.nvim-buffer-local-config| for
--- more details.
---
--- # Comparisons ~
---
--- - 'nvim-tree/nvim-tree.lua':
--- - Provides tree view of file system, while this module uses column view.
--- - File system manipulation is done with custom set of mappings for each
--- action, while this module is designed to do that by editing text.
--- - Has more out of the box functionality with extra configuration, while
--- this module has not (by design).
---
--- - 'stevearc/oil.nvim':
--- - Uses single window to show information only about currently explored
--- directory, while this module uses column view to show whole currently
--- explored branch.
--- - Also uses text editing to manipulate file system entries.
--- - Can work for remote file systems, while this module can not (by design).
---
--- - 'nvim-neo-tree/neo-tree.nvim':
--- - Compares to this module mostly the same as 'nvim-tree/nvim-tree.lua'.
---
--- # Highlight groups ~
---
--- * `MiniFilesBorder` - border of regular windows.
--- * `MiniFilesBorderModified` - border of windows showing modified buffer.
--- * `MiniFilesCursorLine` - cursor line in explorer windows.
--- * `MiniFilesDirectory` - text and icon representing directory.
--- * `MiniFilesFile` - text representing file.
--- * `MiniFilesNormal` - basic foreground/background highlighting.
--- * `MiniFilesTitle` - title of regular windows.
--- * `MiniFilesTitleFocused` - title of focused window.
---
--- To change any highlight group, modify it directly with |:highlight|.
---
--- # Disabling ~
---
--- This plugin provides only manually started functionality, so no disabling
--- is available.
--- Navigation ~
---
--- Every navigation starts by calling |MiniFiles.open()|, either directly or via
--- mapping (see its help for examples of some common scenarios). It will show
--- an explorer consisting of side-by-side floating windows with the following
--- principles:
---
--- - Explorer shows one branch of nested directories at a time.
---
--- - Explorer consists from several windows:
---
--- - Each window displays entries of a single directory in a modifiable
--- scratch buffer.
---
--- - Windows are organized left to right: for any particular window the left
--- neighbor is its parent directory and right neighbor - its child.
---
--- - Explorer windows are the viewport to some part of current branch, meaning
--- that their opening/closing does not affect the branch. This matters, for
--- example, if there are more elements in the branch than can be shown windows.
---
--- - Every buffer line represents separate file system entry following certain
--- format (not visible for users by default; set |conceallevel| to 0 to see it)
---
--- - Once directory is shown, its buffer is not updated automatically following
--- external file system changes. Manually use |MiniFiles.synchronize()| for that.
---
--- After opening explorer, in-buffer navigation is done the same way as any
--- regular buffer, except without some keys reserved for built-in actions.
---
--- Most common ways to navigate are:
---
--- - Press `j` to move cursor onto next (lower) entry in current directory.
--- - Press `k` to move cursor onto previous (higher) entry in current directory.
--- - Press `l` to expand entry under cursor (see "Go in" action).
--- - Press `h` to focus on parent directory (see "Go out" action).
---
--- Cursor positions in each directory buffer are tracked and saved during
--- navigation. This allows for more convenient repeated navigation to some
--- previously visited branch.
---
--- Available built-in actions (see "Details" for more information): >
---
--- | Action | Keys | Description |
--- |-------------|------|------------------------------------------------|
--- | Close | q | Close explorer |
--- |-------------|------|------------------------------------------------|
--- | Go in | l | Expand entry (show directory or open file) |
--- |-------------|------|------------------------------------------------|
--- | Go in plus | L | Expand entry plus extra action |
--- |-------------|------|------------------------------------------------|
--- | Go out | h | Focus on parent directory |
--- |-------------|------|------------------------------------------------|
--- | Go out plus | H | Focus on parent directory plus extra action |
--- |-------------|------|------------------------------------------------|
--- | Reset | <BS> | Reset current explorer |
--- |-------------|------|------------------------------------------------|
--- | Reveal cwd | @ | Reset current current working directory |
--- |-------------|------|------------------------------------------------|
--- | Show help | g? | Show help window |
--- |-------------|------|------------------------------------------------|
--- | Synchronize | = | Synchronize user edits and/or external changes |
--- |-------------|------|------------------------------------------------|
--- | Trim left | < | Trim left part of branch |
--- |-------------|------|------------------------------------------------|
--- | Trim right | > | Trim right part of branch |
--- |-------------|------|------------------------------------------------|
--- <
--- Details:
---
--- - "Go in":
--- - Always opens file in the latest window before `MiniFiles.open()` call.
--- - Never closes explorer.
--- - Works in linewise Visual mode to expand multiple entries.
---
--- - "Go in plus" is regular "Go in" but closes explorer after opening a file.
---
--- - "Go out plus" is regular "Go out" but trims right part of branch.
---
--- - "Reset" focuses only on "anchor" directory (the one used to open current
--- explorer) and resets all stored directory cursor positions.
---
--- - "Reveal cwd" extends branch to include |current-directory|.
--- If it is not an ancestor of the current branch, nothing is done.

---@tag MiniFiles-navigation
--- Manipulation ~
---
--- File system manipulation is done by editing text inside directory buffers,
--- which are shown inside dedicated window(s). See |MiniFiles-navigation| for
--- more information about navigating to a particular directory.
---
--- General workflow:
---
--- - Navigate to the directory in which manipulation should be done.
---
--- - Edit buffer in the way representing file system action.
---
--- - Repeat previous steps until all necessary file system actions are recorded.
--- Note: even if directory buffer is hidden, its modifications are preserved,
--- so you can navigate in and out of directory with modified buffer.
---
--- - Execute |MiniFiles.synchronize()| (default key is `=`). This will prompt
--- confirmation dialog listing all file system actions it is about to perform.
--- READ IT CAREFULLY.
---
--- - Confirm by pressing `y`/`<CR>` (applies edits and updates buffers) or
--- don't confirm by pressing `n`/`<Esc>` (updates buffers without applying edits).
---
--- # How does it work ~
---
--- All manipulation functionality is powered by creating and keeping track of
--- path indexes: text of the form `/xxx` (`xxx` is the number path index) placed
--- at the start of every line representing file system entry.
---
--- By default they are hidden as concealed text (along with prefix separators)
--- for more convenience but you can see them by setting |conceallevel| to 0.
--- DO NOT modify text to the left of entry name.
---
--- During synchronization, actual text for entry name is compared to path index
--- at that line (if present) to deduce which file system action to perform.
---
--- # Supported file system actions ~
---
--- ## Create ~
---
--- - Create file by creating new line with file name (including extension).
---
--- - Create directory by creating new line with directory name followed by `/`.
---
--- - Create file or directory inside nested directories by creating new line
--- with text like 'dir/nested-dir/' or 'dir/nested-dir/file'.
--- Always use `/` on any OS.
---
--- ## Delete ~
---
--- - Delete file or directory by deleting **whole line** describing it.
---
--- - If `options.permanent_delete` is `true`, delete is permanent. Otherwise
--- file system entry is moved to a module-specific trash directory
--- (see |MiniFiles.config| for more details).
---
--- ## Rename ~
---
--- - Rename file or directory by editing its name (not icon or path index to
--- the left of it).
---
--- - With default mappings for `h`/`l` it might be not convenient to rename
--- only part of an entry. You can adopt any of the following approaches:
--- - Use different motions, like |$|, |e|, |f|, etc.
--- - Go into Insert mode and navigate inside it.
--- - Change mappings to be more suited for manipulation and not navigation.
--- See "Mappings" section in |MiniFiles.config|.
---
--- - It is not needed to end directory name with `/`.
---
--- - Cyclic renames ('a' to 'b' and 'b' to 'a') are not supported.
---
--- ## Copy ~
---
--- - Copy file or directory by copying **whole line** describing it and pasting
--- it inside buffer of target directory.
---
--- - Change of target path is allowed. Edit only entry name in target location
--- (not icon or path index to the left of it).
---
--- - Copying inside same parent directory is supported only if target path has
--- different name.
---
--- - Copying inside child directory is supported.
---
--- ## Move ~
---
--- - Move file or directory by cutting **whole line** describing it and then
--- pasting it inside target directory.
---
--- - Change of target path is allowed. Edit only entry name in target location
--- (not icon or path index to the left of it).
---
--- - Moving directory inside itself is not supported.

--- Events ~
---
--- To allow user customization and integration of external tools, certain |User|
--- autocommand events are triggered under common circumstances.
---
--- UI events ~
---
--- - `MiniFilesBufferCreate` - when buffer is created to show a particular
--- directory. Triggered once per directory during one explorer session.
--- Can be used to create buffer-local mappings.
---
--- - `MiniFilesBufferUpdate` - when directory buffer is updated with new content.
--- Can be used for integrations to set |extmarks| with useful information.
---
--- - `MiniFilesWindowOpen` - when new window is opened. Can be used to set
--- window-local settings (like border, 'winblend', etc.)
---
--- - `MiniFilesWindowUpdate` - when a window is updated. Triggers frequently,
--- for example, for every "go in" or "go out" action.
---
--- Callback for each UI event will receive `data` field (see |nvim_create_autocmd()|)
--- with the following information:
---
--- - <buf_id> - index of target buffer.
--- - <win_id> - index of target window. Can be `nil`, like in
--- `MiniFilesBufferCreate` and buffer's first `MiniFilesBufferUpdate` as
--- they are triggered before window is created.
---
--- File action events ~
---
--- - `MiniFilesActionCreate` - after entry is successfully created.
---
--- - `MiniFilesActionDelete` - after entry is successfully deleted.
---
--- - `MiniFilesActionRename` - after entry is successfully renamed.
---
--- - `MiniFilesActionCopy` - after entry is successfully copied.
---
--- - `MiniFilesActionMove` - after entry is successfully moved.
---
--- Callback for each file action event will receive `data` field
--- (see |nvim_create_autocmd()|) with the following information:
---
--- - <action> - string with action name.
--- - <from> - absolute path of entry before action (`nil` for "create" action).
--- - <to> - absolute path of entry after action (`nil` for "delete" action).

---@text # Content ~
---
--- `content.filter` is a predicate which takes file system entry data as input
--- and returns `true`-ish value if it should be shown.
--- Uses |MiniFiles.default_filter()| by default.
---
--- A file system entry data is a table with the following fields:
--- __minifiles_fs_entry_data_fields
---
--- `content.prefix` describes what text (prefix) to show to the left of file
--- system entry name (if any) and how to highlight it. It also takes file
--- system entry data as input and returns tuple of text and highlight group
--- name to be used to highlight prefix. See |MiniFiles-examples| for common
--- examples of how to use it.
--- Note: due to how lines are parsed to detect user edits for file system
--- manipulation, output of `content.prefix` should not contain `/` character.
--- Uses |MiniFiles.default_prefix()| by default.
---
--- `content.sort` describes in which order directory entries should be shown
--- in directory buffer. Takes as input and returns as output an array of file
--- system entry data. Note: technically, it can be used to filter and modify
--- its elements as well.
--- Uses |MiniFiles.default_sort()| by default.
---
--- # Mappings ~
---
--- `mappings` table can be used to customize buffer-local mappings created in each
--- directory buffer for built-in actions. Entry name corresponds to the function
--- name of the action, value - right hand side of the mapping. Supply empty
--- string to not create a particular mapping.
---
--- Default mappings are mostly designed for consistent navigation experience.
--- Here are some alternatives: >
---
--- -- Close explorer after opening file with `l`
--- mappings = {
--- go_in = 'L',
--- go_in_plus = 'l',
--- }
---
--- -- Don't use `h`/`l` for easier cursor navigation during text edit

---
--- # Options ~
---
--- `options.use_as_default_explorer` is a boolean indicating whether this module
--- should be used as a default file explorer for editing directories (instead of
--- |netrw| by default).
---
--- `options.permanent_delete` is a boolean indicating whether to perform
--- permanent delete or move into special trash directory.
--- This is a module-specific variant of "remove to trash".
--- Target directory is 'mini.files/trash' inside standard path of Neovim data
--- directory (execute `:echo stdpath('data')` to see its path in your case).
---
--- # Windows ~
---
--- `windows.max_number` is a maximum number of windows allowed to be open
--- simultaneously. For example, use value 1 to always show single window.
--- There is no constraint by default.
---
--- `windows.preview` is a boolean indicating whether to show preview of
--- file/directory under cursor. Note: it is shown with highlighting if Neovim
--- version is sufficient and file is small enough (less than 1K bytes per line
--- or 1M bytes in total).
---
--- `windows.width_focus` and `windows.width_nofocus` are number of columns used
--- as `width` for focused and non-focused windows respectively.
