     }
     ```

- [x] Refactor preview using a common trait & macros
- [x] fix previewing non normal file hangs by preventing previewing...
- [x] send a notification when files are copied or moved
- [x] regex matcher (w) updates as you type
- [x] help displays current keybindings
- [x] dual pane. Only two tabs
- [x] allow multiple keybindings for same action
- [x] single pane if width is low
- [x] disks:
  - [x] simplify disk space read,
  - [x] hold a sys reference in status
  - [x] add shortcut to mount points
- [x] dissociate action from status / tab

  - [x] char('T') for thumbnail
- [x] togglable dual panes... with default mode for low size
- [x] FIX: non ascii typed symbols crash the application.
      Don't use non ascii chars atm. It's hard to navigate in a string of non ascii chars and
      would require another crate.
- [x] non ascii char support. ie graphemes. Simply use a vec of chars and collect it when needed.
- [x] Fix: / (slash) in newfile, newdir crashes the app with strange errors. Use sanitize_filename
- [x] goto relative path. Look for directory in current path
- [x] keeps searching for same result with f.

  When a search is made (/),

  - if the user completes (TAB) and Enter, only this file can be found.
  - if the user doesn't complete but Enter immediatly, we can find any file containing this name.

    The user can search from next element with f.

## Current dev

### Version 0.1.24

- [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] display mode / edit mode. Separate display (normal, tree, preview) from any other mode.
- [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.

- [ ] config loading : https://www.reddit.com/r/rust/comments/17v65j8/implement_configuration_files_without_reading_the/
- [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] move every src to a related folder
- [x] refactor regex. Allow regex match in tree
- [x] FIX: can't jump to file from tree mode
- [x] refactor chmod into its own mod
- [x] refactor node creation (file or directory) in its own mod
- [ ] refactor password.
  - [x] only one enum
  - [ ] hold passwords somewhere else
- [x] FIX: browsing a file where "modified" time is in future crashes the application.
      The error comes from refresher.rs and happens with poorly configured iso files.
- [x] Fix the error itself,
- [x] log a message when we encounter such a file, since there's not much we can do
- [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] don't allow rename of parent or self folder (. & ..)
- [x] FIX: print on quit requires to drop everything holding a terminal
- [x] Improve refresh actions. Subfolders in tree mode are now watched.
- [x] Trait LineDisplay for EditMode
- [x] Split tree & lsl drawing into smaller methods
- [x] cargo clippy -- -D clippy::pedantic -D clippy::nursery
      1100 -> 891 errors
- [x] FIX: resizing deselects the current file.
- [x] FIX: first line use selected tab even when not selected
- [x] refactor bulk. Made it a bit simpler
- [ ] status refactoring. Moved every "menu" to a separate file.
  - [x] moved attributes
  - [ ] moved all methods relative to menus
- [ ] refactor file opening. It's a mess - WIP
- [ ] Only store one Selectable thing in status

## TODO

- [ ] mount usb key - should be merged with mtp
- [ ] document filepicking (from my config etc.).
- [ ] avoid multiple refreshs if we edit files ourself
- [ ] FIX: tab.selected() should return Option<&FileInfo>
- [ ] use widget for every drawable element. First line should be a collection of widget which are drawned
- [ ] while second window is opened, if the selection is below half screen, it's not shown anymore.
      Scroll to second element if needed
- [ ] 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

- [ ] display / event separation. use async and message passing between coroutines

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

- [ ] update the animation
- [ ] exec multiple flagged files
- [ ] shell menu

  - [ ] allow non tui like wttr, diff, bat, tail -n etc.
  - [ ] more options like "use flagged files" for diff

- [ ] build option to force reset of config file, warn the user at first start
- [ ] optionable "plugin" started from config file. Would require every option to be `Option<Plugin>` and may cause problems with the borrow checker.
- [ ] edit folder like a buffer [oil like](https://github.com/stevearc/oil.nvim)
- [ ] allow pipe in execution
- [ ] refactor cryptdevice and iso_file

  - [ ] mode to handle those mounts. ATM it's all over the place...
  - [ ] allow mounting some other devices
  - [ ] list non mounted devices, list all mount points
  - [ ] act on them

- [ ] Version 0.1.50 : safety & memory usage

  - [ ] there's a memory leak somewhere
  - [ ] preview of big files (or whatever file) should only read chunk of the file,
        not the whole thing. Previewing a 5gB iso file uses up to 15gB of ram, which will crash any system.
        or should it ?
        Simple solutions:

        - only reads a buffer
        - limit to xxx filesize

- [ ] Version 0.2.0 : tests

  - [ ] tests
  - [ ] remove references to local thing
  - [ ] translations i18n

- [ ] Version 0.3.0 : dark/light theme, transparency etc.

- [ ] Version 0.4.0 : 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.
