Changelog

0.2.2 — 2026-04-12

Bug-fix release: Python program output now shows in the Console pane, and breakpoints restore for files opened on the command line.

Fixed

• Python print() output appears in the Console pane. The debugpy launch config now sets console = "integratedTerminal", so debugpy routes stdout/stderr via RunInTerminalRequest into dapui's Console buffer (which is already registered as dap.defaults.fallback.terminal_win_cmd). Previously debugpy defaulted to internalConsole and emitted OutputEvents that nvim-dap forwards to the REPL buffer — which turbo-debug's layout deliberately omits, so program output vanished. Interactive input() now also works.
• Breakpoints restore for files opened on the command line. nvim foo.py fires BufReadPost for foo.py before turbo-debug's deferred setup() runs, so persistent-breakpoints.nvim's BufReadPost autocmd missed the startup buffer and saved breakpoints never came back. After setup, turbo-debug now sweeps already-loaded buffers once via load_breakpoints() (idempotent; placed after sign_define so the first paint uses turbo-debug's emoji signs instead of dap's default B).

0.2.1 — 2026-04-12

Language coverage release. 10 new DAP adapters bring built-in support from 12 to 22 languages, prioritized by language popularity and DAP adapter maturity.

Added

• Dart (with optional Flutter) — auto-detects flutter on PATH and adds a "Launch Flutter app" configuration alongside the plain Dart file launch. Uses dart debug_adapter / flutter debug_adapter.
• Bash / Sh — bash-debug-adapter with automatic bashdb_dir probing from the mason package path.
• R — vscDebugger R-package integration. Preflights the package via Rscript and silently skips registration if it's missing.
• Elixir — elixir-ls-debugger with mix_task launch (default task test). Falls back to the mason package debugger.sh if the wrapper binary isn't on PATH.
• Haskell — haskell-debug-adapter.
• OCaml — ocamlearlybird.
• Zig / Nim / Crystal — routed through the existing codelldb adapter via filetype extension (no new adapter; just added filetypes to the existing codelldb configuration).
• F# — routed through the existing netcoredbg adapter (same .dll-launch flow as C#).

Internal

• Extended tests/test_adapters.lua to cover the three new modular adapter modules (dart, bash, r).
• All new registrations follow the existing find_executable + loader.register pattern and silently skip when the required binary isn't found — matches the "no noise when prereqs missing" invariant of the previously-shipped adapters.

0.2.0 — 2026-04-12

Major UI rework and stability release. Two floating chrome bars replace the old single toolbar, every resize/tabline-toggle edge case is handled, and every highlight now derives from the user's colorscheme.

Breaking changes

• quit_exits_mode option removed. q is now context-aware: if a DAP session is running, q terminates the session but keeps debug mode active (so you can read the Console / inspect post-mortem state). Press q again to exit debug mode.
• help_on_enter default is now false (was true). The control bar always shows (?) help, so the auto-popup is no longer needed. Set to true to restore the splash behavior.
• Default layout changed. Sidebar panes are now Call Stack → Scopes → Watches → Breakpoints (all 25%). REPL is no longer in the default layout — press E during debug mode to open it as a floating window.
• Console pane sizing. Bottom Console pane is max(8 rows, 20% of editor lines) (previously hardcoded). Configurable via console_height.

Added

• Two-bar floating chrome, independent of any statusline plugin:
  • Status bar (top, 2 rows): brand, live dap.status() text, state chip (DEBUG · READY / · RUNNING / · PAUSED)
  • Control bar (bottom, 2 rows, above statusline): clickable buttons for continue, step over, step into, step out, restart (during session), terminate; (?) help right-anchored
  • Italic qualifiers (over, into, out) on step controls — dropped automatically at narrow widths
• Keymap-aware control bar: legend reflects the user's actual remapped keys (honors keys override; disabled actions are omitted)
• IP arrow markers on stopped lines: paired 👉 gutter sign (priority 500 so it always wins over breakpoint signs) + 👈 REASON virtual text at EOL
• Optional debug-mode colorscheme via colorscheme option — theme swaps on debug enter, restores on exit
• Theme-agnostic separator color: derives from WinBar.fg so the bar chrome matches any colorscheme; global WinSeparator override during debug mode gives the whole UI a consistent edge color
• clear_console_on_start (default true): wipe Console scrollback on session start/restart while preserving the terminal channel
• collapsed_scopes (default { "Registers" }): auto-collapse noisy scopes; codelldb doesn't mark Registers expensive even though it's a huge dump
• max_value_width (default 2000): per-line truncation for values in Scopes/Watches; prevents register-dump bleed
• console_refresh_ms (default 50): trailing-edge throttle for Console repaints under high-throughput stdout
• sidebar option — "left" (default) or "right"
• active_window_highlight (default true): dim inactive dapui pane borders so the focused pane is visually obvious
• W and K in visual mode: watch / hover operate on the selection
• Live dap.status() polling via User DapProgressUpdate autocmd — status text stays current across progress messages
• Source window is focused before DAP jumps on event_stopped, so stepped-into library files open in the source area (not in a bar or dapui pane)
• Console repaint throttle prevents editor lag under chatty programs

Changed

• Bars are now real splits (not overlapping floats) — dapui and source windows tuck between them naturally
• pin_dapui_sizes() only re-pins on EXTERNAL geometry changes (bufferline tabline toggle, wincmd =) detected by total-height delta; user's manual pane drags survive
• ensure_dapui() runs ONCE per plugin lifetime (not per M.enter), avoiding "Debug adapter didn't respond" timeouts on toggle
• Bars clamp to exactly 2 rows on every VimResized / WinResized (prevents stray EOB ~ when nvim grows a fixed-height window)
• setup() is now fully idempotent — safe to call multiple times with different opts, and plugin/turbo-debug.lua's deferred auto-setup yields to explicit user setup({...})
• Copyright holder updated to Stephen Waits <steve@waits.net>

Fixed

• Bars recreate themselves if killed by shrink-below-minimum resize or tabline appearance/disappearance
• Inherited winbar from the splitting source window is cleared on bar windows (was showing phantom separator rows)
• Layout re-asserts correctly after wincmd = (tiny-equalizer pass)
• Sidebar proportions stable across re-entry (no drift across toggles)
• Bar separators bright on both outward edges (top-of-sbar, bottom-of-cbar)
• Deferred dependency loading: plugin/turbo-debug.lua waits for vim.pack.add to finalize runtimepath before calling setup()

Internal

• Extracted 10+ helper functions in mode.lua (win_ok, buf_ok, is_dapui_pane_ft, for_each_dapui_pane, safe_extmark, bar_set_lines, safe_set_height, if_still_active, invalidate_dead_bars, focus_source_win, unset_and_restore, install_cs_listener) — deduped ~25 call sites
• Data-driven sign definitions (breakpoints.lua) and Python interpreter candidate probing
• Dead code removed: unused reposition_bars stub, vestigial sbar_zones / handle_sbar_click click infrastructure (status bar has no clickable zones)
• Added regression tests: test_render_bars (sbar/cbar output, dimensions, zones, overflow fallback), test_highlights_cs (ColorScheme augroups, highlight re-apply), test_helpers (keyof branching, source_window filtering)
• stylua.toml added; all Lua code formatted
