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

Currently looks like this:

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 (Gtk, Qt)

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)

Keybindings

Ctrl + P - Move selection up
Ctrl + N - Move selection down
Ctrl + Enter - Do selected action

F1 - Show frames per second
F2 - Toggle 60fps framelock
F3 - Debug/Test screen, mostly gibberish

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, ...)
• Mouse coords translation to local component coords and list item click
• Support font family by name, using fc-list for getting installed fonts and filenames
• Proper XDG standard support for XDG_DATA_DIRS regarding applications and icons
• Implement component focus.
• UI reset after soft-close.
• Implement workspaces! Good enoug progress for now.
• Smoooooth cursor movement and smoooooth list scrolling with key navigation working.
• Implement tray! DBus is a mess, but a useful mess... Icon events and refresh is done
• Standardize button state. Only field is active.
• Implement textinput cursor movement and Unicode support.
• Implement by_name_typed in order to get the specific implementation of a given UIComponent
• Layout container hide/show
• Calculator command
• ! Replace SDL2_image with something more light dependency-wise
• ! Make LayoutManager implement UIComponent so it can be called directly to update and draw
• Get system default font and use it as a best effort font in case requested font doesn't exist
• Prompt window available to actions
• More prettier (this will always be here)
• Fuzzy search (fzf dependency?)
• 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

! - means ongoing

Wayland support

tudo will try and detect the display manager being used. It uses XDG_SESSION_TYPE for this and sets SDL_VIDEODRIVER to wayland If it doesn't work or you're having issues just add SDL_VIDEODRIVER=wayland to your environment variables
