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

Wayland support

Just add SDL_VIDEODRIVER=wayland to your environment variables
