t-code v0.3

T-Code v0.3 Debug and Theme Update

t-code is now an IDE with a debugger. This release also adds quick fixes, code folding, color themes,
panels you can move around, and right-click menus everywhere, while keeping memory use low.

Debugging (new)

• F5 builds with debug info and starts the program under gdb (14 or newer, gdb -i dap).
  F9 or a click left of a line number sets a breakpoint. A right click sets a condition.
• F10 / F11 / Shift+F11 step over / into / out. F6 pauses, Shift+F5 stops and
  Ctrl+Shift+F5 restarts.
• Run and Debug panel (Ctrl+Shift+D):
  • Variables: values that changed since the last pause are colored, and arrays and structs
    open like folders.
  • Watch: expressions, kept per project.
  • Call Stack: frames in libraries are folded into one row.
  • Breakpoints: the full list, across all files.
• Values under the pointer while paused, and an evaluate line (with -exec for gdb commands).
• Crashes, from a segfault or AddressSanitizer, stop on the bad line and are explained in one
  plain sentence.
• Disassembly View:
  • the function's instructions, with its source lines between them;
  • stepping by instruction, instruction breakpoints, and registers.

Editor

• Quick fixes (Ctrl+.), such as a missing ;, a missing #include or a misspelled name,
  plus clangd's refactorings.
• Go to Symbol in File (Ctrl+Shift+.) and Switch Source / Header (Alt+O).
• Code folding (Ctrl+Shift+[ / ]) and sticky scroll: the heads of the enclosing
  function, loop or namespace stay at the top.
• Highlights:
  • the cursor on a name lights up that symbol's uses;
  • code that an #if leaves out is dimmed;
  • git changes show in the strip beside the minimap.
• A right-click menu in the editor with the important commands.
• A save conflict bar when the file changed on disk: Overwrite, Reload or Compare, instead of
  silently overwriting.
• make writing compile_commands.json is picked up by itself, with no clangd restart.

Window

• Color themes: Dark Classic, Gruvbox and other dark and light themes, each with a preview, in
  a rounded or square look. You can edit settings.ini, theme.css and the editor's style
  scheme by hand.
• Panels move between docks: drag a panel's icon to the left, bottom or right. Each panel has
  a show/hide button in the title bar. "View: Reset Panel Layout" puts everything back.
• Open in New Window: a second window for the same project, sharing clangd.
• Right-click menus on tabs, Open Tabs, files, Source Control, search results, terminals and
  the debugger's lists.
• Source Control:
  • commit details on hover, and "Open Commit Details" shows a commit with its diff;
  • collapsible sections.
• Comparisons open at the first change.
• Settings pages listed on the left.

Run other languages

Ctrl+F5 runs scripts by their interpreter: Python, JavaScript / TypeScript, shell, Lua, Ruby,
Perl, PHP, Go, Java, or any file with #!. It also runs Cargo, Go, npm, Maven and Gradle
projects, and Python from its root with its venv.

Faster

• Semantic coloring is updated by delta: on an 18 000-line file, an edit used to stall the window
  for about 280 ms and now takes under 1 ms.
• Git comparisons no longer run on the main thread.

Keys that changed

• F5 now starts debugging. Build and run moved to Ctrl+F5, and Ctrl+Shift+B still
  builds only.

Install

Distribution	Command
Fedora 44	sudo dnf install ./t-code-0.3.0-1.fc44.x86_64.rpm
Arch Linux	sudo pacman -U t-code-0.3.0-1-x86_64.pkg.tar.zst
Debian 13	sudo apt install ./t-code_0.3.0-1_amd64.deb
Void Linux	t-code-0.3.0_1.x86_64.xbps (glibc) or t-code-0.3.0_1.x86_64-musl.xbps (musl), with xbps-rindex -a and xbps-install

Check the downloads with sha256sum -c SHA256SUMS. Debugging needs gdb 14 or newer; the packages
recommend it.

Kown Issues

• Sometimes right click causes a loop with data race and UI freeze. Reason found and fixed, next release will not have this problem.
