TUDO

TUDO Univeral Desktop Operator
Transforming User-Device Operation
Everything (in Portuguese)
Take a pick at the meaning.

Desktop Omnibar. Type and launch stuff. Pretty simple.
Semi-serious learning project.
Meant to be used as a wristwatch. You want it there but you don't need to look at it all the time.
Maybe just replace the concept of a top/bottom bar with the clock and stuff

Nice-to-haves and objectives

  • As low latency as possible both in launching and in using
  • Fast indexing
  • Tray icons, interactable
  • TOML configuration (with sane defaults)
  • Extendable in Lua
  • Minimal list of dependencies, i.e no UI toolkit

Thing I will not implement

  • TTF parser
  • HTTP client

Dependencies

  • SDL2 with ttf and image

Features

  • Application launcher (XDG only)
  • XCB and EWMH based window switching (supports: i2, awesome, xfce, etc.)
  • pass secrets integration
  • (Really) Minimal UI lib with a couple of components and a layout manager
  • Primitive Lua sources support (no function exporting yet)
  • Texture cache (fonts, icons and generic image files)
  • Asynchronous load of item sources in order to reduce startup time (no async/await, simple thread spawn)

Sources

  • XDG Applications
  • EWMH based window switching (supports: i3, awesome, xfce, etc.)
  • tmux sessions
  • pass secrets
  • TODO: Notion Notes
  • TODO: Browser tabs (this one is a challenge)

Rolling Dev Notes

  • Solve the mistery of proper font atlas, right now using direct render from SDL2 ttf. It's kerning...
  • action tags and search for action (:run, :window, :secret, etc)
  • Icon files may not exist even if referenced by XDG icon files format
  • Various font sizes and faces. This was hard....
  • Primitive animations
  • tmux list source items, open default terminal in a given session
  • Async load sources
  • Implement drawing 'toolkit' context containing Sdl, Canvas, TextureCreator, etc
  • Show that the sources are still loading (really simple, but working)
  • Prevent from starting multiple instances
  • Create .config folder, need to check if this is cross platform
  • Lua based configuration (very early but promising)
  • Migrate to mlua, due to serde support
  • Support for multiple screens
  • ! Layout builder and simplified component access
  • Component get_state and set_state
  • Use a new component spinner to sinalize sources loading
  • Extend canvas drawing functions implementing more complex shapes (rounded rect, circle, quadrants, ...)
  • ! Implement component focus (which will receive events)
  • Mouse coords translation to local component coords and list item click
  • Get system default font, maybe
  • Prompt window available to actions
  • More prettier
  • Better search (fuzzy)
  • Notion integration for notes. Depends on a prompt action.
  • Investigate async/await for async source loading
  • Dashboard-like widgets for things like metrics
  • Submenus for some actions
