v0.2.0
340 color themes that restyle the UI and the terminal palette together, a new PTY layer, and windows that can no longer leave the screen.
Gaurav Gosain
Eight commits, two of them big: tuios got themes, and it got a new PTY layer underneath every window. The rest is cleanup that matters on the way out the door, literally in one case, since this release is also where tuios learned to restore your terminal properly on exit.
Themes
tuios now ships with over 340 color themes via bubbletint, selected with
--theme (default: tokyonight). A theme does not just recolor the chrome. A
custom SGR handler maps the 16 ANSI colors to the theme's palette, so ls,
vim, and htop running inside a window pick up the theme too, instead of
whatever hardcoded colors they would normally show. 256-color and RGB escape
sequences pass through untouched, so applications that ask for exact colors
still get them.
Window borders use the palette to carry state: unfocused windows take the
theme's red, a focused window in window mode is bright cyan, and in terminal
mode it is bright green. --list-themes prints all of them and
--preview-theme shows a theme's 16 ANSI colors with hex values before you
commit to one.
A new PTY layer
Every terminal window sits on a pseudo-terminal, and this release swaps the library that provides it: go-pty out, charmbracelet's xpty in, for a cleaner API and better Windows ConPTY support. The migration broke shell startup first. Processes were no longer getting the PTY as their controlling terminal, which shells like fish require, so windows spawned and immediately died with exit status 1. The fix, in this same release, sets up the process session and controlling terminal explicitly, matching what the old library did implicitly.
Smaller changes
- Windows can no longer be dragged or resized off screen. Bounds checking keeps them inside the viewport and out of the dock area, which also fixes rendering artifacts at the edges.
- tuios exits cleanly. SIGINT and SIGTERM are handled, and on the way out it disables mouse tracking, restores the cursor, and leaves the alternate screen, so your shell prompt is not corrupted.
- The README no longer disagrees with itself about the background refresh rate (30Hz, not 20Hz). Caught by ShalokShalom.
- The nix packaging workflow now triggers on tag pushes, not just release events, so it actually runs on every version.
