    The user can search from next element with f.

- Header (path, filename), Footer (other informations).
- Every window can be clicked. Header, Footer, Files, Menus. Selectable element from menu can be clicked.
- Integrated a lot of commands into `TuiApplications` or `CliApplications`.
- Session for display settings. Settings are saved after each modification.
- Better (?) keybindings. Alt+char open a menu whose name starts with this char.
- Refactoring `lib`. Moved file to a few folders, separated display from status.
- Many bug fixes

#### Changelog

- [x] refactor term manager. Separate content construction from drawing.
- [x] better messages when asking a password
- [x] FIX: trash is buggy. Can't delete definitely. Display is wrong when empty.
- [x] FIX: cursor is off by one in password

- [x] FIX: NVIM listen address won't update if neovim is restarted while fm is still running
- [x] FIX: next is wrong when folded.
      Needs a lot of change. Can't fix everything. ATM if a childnode is folded, unfolding also unfolds every child.
      IDK how to avoid that without rewriting everything.

      We need to do next on node until we reach a displayed node. It's not good.

- [x] separate display_modes completely. Normal -> lsl (?), Tree, Preview.
      PathContent is only used in Normal and should be associated with it.
      Reseting display should switch back to user setted display.
      Preview isn't like Normal & Tree since it doesn't display files at all.

- [x] prevent logging the same file multiple times. Massive change which requires a new lazystatic element
- [x] regroup commands in one place
- [x] FIX: clicking outside above files crashes
- [x] Clickable first line. Each first line element can be clicked, resulting in an action

- [x] Clickable layout
  - [x] 1 row : address & file
  - [x] 50% or 100% : files

  - [x] last row : infos with fixed sizes
- [x] Session with display settings like [felix](https://github.com/kyoheiu/felix/blob/main/src/session.rs)
  - [x] display settings aren't read from args or config file except for "display all".
  - [x] read (using serde_yaml) and write (using serde::Serialize) display settings from a [session file](~/.config/fm/session.yaml).
  - [x] make every session element private, ensure we read the correct setting for dual.
- [x] FIX: opening help or fuzzyfindhelp crashes if a listed action has no keybind (aka. the user overwritten a keybind without creating one for old action).
- [x] !command & cli_application print the command run and the output
- [x] Pre release
  - [x] Fix last missing items
  - [x] check installation (remove config, cargo build)
  - [x] readme
  - [x] describe what was done succintly

### Version 0.1.25

#### Summary

- Improve scrolling in tree mode.
- Bulk & normal rename: create intermediate folders when renaming.
- Bulk now asks a confirmation before execution.
- Scroll to selection when opening a menu. Selected file should alway be displayed in top window.
- Scroll completion & navigation menus.
- Configurable cli applications. See `~/fm/cli.yaml`
- Simplify tui config files. Remove `cwd` boolean parameter. Doesn't break old config files.
- Display the number of entries as the size of a directory instead of '-'. Might affect performance for very large directories.
- Enable logging with `-l` or `--log`. **Nothing is logged anywhere without this flag.**
- FIX: Tree mode. Unfolding a directory unfold its children
- BREAKING: Use specific argument read from config file to run a command at startup for most common terminal emulators.
  It allows the user to setup a specific terminal unknown to me and use it with fm.
  To make this work, it will require the user to update its config file by copying the last part: "terminal_emulator_flags:..."
- FIX: entering an inaccessible dir or writing in any way to a readonly dir shouldn't crash the app anymore...
- Display & Update separation. Use a thread for display, allowing 30 fps. It uses more CPU :(
  This feature is subject to change in future versions.
- Flagged display mode. Enter with <F> and show all your flagged files. You can rename, open, trash, delete, bulk rename, open, open with etc.
  Custom and simple search (filename containing input).
  Jump to the file with <return>
  ATM both "edit::jump" and "display::flagged" show the same content. The former may be removed soon.
- Configurable menu colors. Every color used on screen is now configurable like file colors.

### Version 0.1.26

#### Summary

- BREAKING: removed jump mode completeley.
  You can see your flagged files in the display::flagged mode, default bind: <F>.
- BREAKING: removed all MOCP controls from fm. What was it doing there anyway ?.
  Those change won't break your config file. While building the application, line with reference to removed binds will be erased.
- search with regex. You can search (Char('/')) a regex pattern. Search next (Char('f')) will use that regex.
- left or right aligned and clickable elements in header
- shift+up, shift+down while typing something cycle trough previous entries.
  Those are filtered: while typing a path, suggestions are limited to previous pathes, not previous commands.
- shift+left erases the whole input line
- wrap tuikit::event into custom event. Use an mpsc to request refresh and bulk execution.
  While editing filenames in bulk, the application isn't bloked anymore.
- improve neovim filepicking. While ran from a neovim terminal emulator, use the flag `--neovim`. Every _text_ file will be opened directly in current neovim session.
  Watchout, if you try to open text & non text files at the same time, it will run a new terminal with your text editor instead. Don't mix file kinds.
- Dynamic filtering while typing a filter
- Search as you type: do / then type a pattern and you will jump to the match.
- replace `tar tvf` by `bsdtar -v --list --file`. Which can preview .deb and .rpm files
- preview torrent files with `transmission-show`
- preview mark, shortcut & history content in second pane while navigating
- zoxide integration. While typing a path in "Goto mode" (default keybind "alt+g"), the first proposition will come from your zoxide answers.

### Version 0.1.30

#### Summary

- shell & exec menu allow %t as terminal expansion. It allows you to open a file in a new terminal.
  `! %t nvim %s` will open the selected file with neovim in a new terminal.
- cd command (Alt+g) includes children of a path (detected as soon as you type a /)
- double clic on a menu item to execute it. Same as a clic then press enter.
- Fixed a bug where search completion would be made before the char is inserted, displaying wrong results
- Fixed a bug where preview were built for second pane even if it wasn't visible, wasting ressources
- Move as you type. In Cd menu (Alt+g), the display and preview is updated as you type.
  Pressing Esc (leave mode) go back to where you started from.
  You need to validate with enter.
- Sync left tab from right path shift+left. shift+right go the other way.
- A lot of refactoring:
  - flagged files,
  - input history,
  - application start, main loop & quit,
  - display
  - menus
- Fixed a bug where leaving a menu while a tree is displayed resets the index.

## Current dev

### Version 0.1.31

#### Summary

- tuikit is replaced by crossterm & ratatui.
- skim is replaced by nucleo.

  tuikit and other crates created by the same author aren't maintened anymore.
  fm relied a lot on the work of a single author: terminal events, rendering,
  fuzzy finding, parsing of ANSI output etc. were all written by the same developper
  and it created a lot of technology debt.

  Maintaing this code required to fork some repositories which was a lot of work and could create more debt if someone took the project further.

  It's been a pleasure to work with those crates but I believe it's the right move.

  By switching to maintened crates we ensure to be able to evolve the project
  more safely.

  Most of the code is adapted "as is". I did my best to keep everything as it was
  and don't break anything.

  The fuzzy finder looks really different but all its rendering is now much simpler.

- double click is replaced by middleclick. Less intuitive but much more convenient in crossterm.
- redirection in shell commands.

  You can enter a shell command by typing `!` then `ps -ef | grep %s` and see the if the selection is beeing executed.
  It allows you to execute complex shell commands and see their output.

  Expansion haven't change (%s selection, %p current path, %n filename, %e extension, %f flagegd files, %t terminal emulator)
  Strings like `echo "Hello World"` or `echo 'Hello World'` should be processed correctly.
  Tokens like `*` and shorcuts like `~` are recognized and dealt by sh.
  Most environment variables aren't known since it's a new shell which run the command. You can still do `!` `export a=2; echo $a` and see... `2` on the output.
  It also works for sudo commands : `sudo ls %s | grep pattern` will ask a password and execute `sudo ls your/selected/path | grep pattern`.

  There's a lot of steps and it's surelly buggy, I'll have to simplify it as much as possible in a future version.
  The interface won't change, the internal will surelly do.
  Since this parser is used everywhere, it means you can define custom commands with redirections. I can't think of an usage but may be you will !

- Bugfixes:
  - FIX: trash: bottom line is wrong "Enter" doesn't select but restore - refresh & reselect
  - FIX: input_simple: when height is low, static elements are out of the window
  - FIX: crash when deleting a file in tree mode
  - FIX: diplay directory last line shouldn't be printed - erase the last line before printing log.
  - FIX: Alt+c (open config file) should be betterly logged
  - FIX: shortcut. dedup_slow keeps crashing. Sort unstable + dedup will do the trick.
  - FIX: second pane ueberzub 1 char too left

## TODO

### Next version

- [ ] document every public function / method. Done for struct, enum & macros.
  ```sh
  % cargo rustdoc -- -D missing_docs 2>&1 | grep error | wc -l
  492
  ```
- [ ] navigate: home should go to first, end should go to last. g/G can't be used here since it can be a navigation
- [ ] static lines (from display, menu, content per mode) can be cut out of the window. Should use the space on the right
- [ ] chmod is crap
  - [ ] "+" should enter chmod
  - [ ] chmod should detect text input and react to it.
    - [x] 777 is accepted
    - [ ] rwxrwxrwx should be accepted
    - [ ] +x & all chmod syntax should be accepted too
- [ ] display preview of flagged files in menu flagged.
- [ ] why have a bottom line in menu if the binds are always explained ?
- [ ] preview should display how the file is previewed even if it's obvious "Previewed as binary file"
- [ ] use anstyle crate to parse ANSI lines. Use anstyle_crossterm for conversion..
- [ ] shell_command_parser refactor. The whole pipeline should be simplified as much as possible.
  - [ ] new shell command expansion %c current clipboard
- [ ] menu / rendering / widgets
      What is a menu in fm ?

  - render : should be cached as much as possible. For many menus, it doesn't change much.
  - actions : should be attached to menus in a way or another. Don't store everything in status
  - [ ] header should be a trait implemented by Header (-> FilesHeader), PreviewHeader, MenuHeader or event variants
  - [ ] at this point I should list what it should do for every menu and rewrite it from scratch
  - [ ] menu reset is a mess, menu set is a mess, status refresh is a mess
  - [ ] don't store shortcut. Always get them on the fly.
  - [ ] should all menus be calculated on the fly ? config/hardcoded -> ~static~ build -> filter if something -> render / actions

- [ ] ratatui component for progress bar for copymove

- [ ] previewing text files with bat ? binaries with xxd

  - [ ] could remove the whole syntaxed stuff
  - [ ] simplify previewing since half the methods are gone
  - [ ] heavilly rely on ansi string parsing

- [ ] Walkdir::new in tree building instead of exploring by hand
- [ ] common trait to validate a data : input string, config, args...
- [ ] google drive should be a display ?
- [ ] previews: find a way to stop

### Other ideas

- [ ] Focus & mouseover. Mousemove require raw terminal mode.. Requires to rewrite every event (Mousepress, mouse release etc.)
      Another motivation to switch to ratatui + crossterm.
- [ ] ideas from broot : https://dystroy.org/broot/#apply-commands-on-several-files
- [ ] floating windows ?
- [ ] rclone
- [ ] use the new mpsc event parser to read commands from stdin or RPC
- [ ] [opener file kind](./src/io/opener.rs): move associations to a config file
- [ ] open a shell while hiding fm, restore after leaving
- [ ] document filepicking (from my config etc.).
- [ ] avoid multiple refreshs if we edit files ourself
- [ ] remote control

  - [ ] listen to stdin (rcv etc.)
    - [ ] follow change directory
    - [ ] when called from a file buffer in nvim, open with this file selected
  - [ ] nvim plugin - set a serverstart with a listenaddress, send it to fm
  - https://github.com/KillTheMule/nvim-rs/blob/master/examples/basic.rs
  - https://neovim.io/doc/user/api.html

- [ ] temporary marks
- [ ] context switch
- [ ] read events from stdin ? can't be done from tuikit. Would require another thread ?
- [ ] pushbullet ?

- [ ] update the animation

- [ ] build option to force reset of config file, warn the user at first start
- [ ] edit folder like a buffer [oil like](https://github.com/stevearc/oil.nvim)
- [ ] allow pipe in execution

- [ ] tests
- [ ] remove references to local thing
- [ ] translations i18n
- [ ] dark/light theme, transparency etc.
- [ ] plugins

  - which language ?
  - what for ?

## Won't do

### auto stuff

All of this stuff can be done easily through a shell command or automatically. I'm not sure I wan't to bloat fm with it.

- [ ] auto mount usb keys ??? just use udiskie (started automatically) and udiskie-umount /mount/point
- [ ] cloud services (apple, microsoft, google, dropbox etc.)
- [ ] ftp

### Chat GPT ideas

Tell me 10 cool features a TUI file manager could have

Sure! Here are 10 cool features a TUI (Text-based User Interface) file manager
could have:

Easy navigation: A TUI file manager should allow users to navigate through
directories and files quickly and easily using keyboard shortcuts.

File previews: Users can preview the contents of a file without having to open
it. This feature can be particularly useful for large text files, images, or
videos.

Customizable interface: A TUI file manager should be customizable so that users
can choose the information they want to see on the screen, such as file size,
modification date, and file type.

File operations: Basic file operations like copying, moving, and deleting
should be easily accessible and efficient to perform.

Bulk operations: A TUI file manager should allow users to perform bulk
operations on multiple files at once, such as renaming or deleting them.

Tabbed interface: A tabbed interface allows users to have multiple directories
open at the same time, making it easy to move files between them.

Bookmarking: Users can bookmark frequently used directories for quick access.

Integrated terminal: A TUI file manager can include an integrated terminal to
execute commands without switching to another application.

Search functionality: Users can search for files based on their name, content,
or other criteria, with the search results displayed in real-time.

Cloud storage integration: TUI file managers can integrate with cloud storage
services like Dropbox, Google Drive, or OneDrive, allowing users to manage
their cloud files directly from the file manager interface.
