Three refinements driven by the latest screenshot:
- TurboDebugBar highlight now links to Normal (was StatusLine). The
StatusLine bg is usually darker than Normal in most colorschemes,
which created a visible seam between our bar and the surrounding
dapui pane headers (which inherit Normal/WinBar bg). Linking to
Normal makes the bar blend so the overall UI reads as one unified
surface rather than two mismatched strips.
- Console height now `min(5, 15% of avail)` with a 3-row absolute
floor. Previously used `max(5, 15%)` which let Console balloon on
tall terminals — misread the user's "minimum of 15% OR 5 rows"
direction. Console is ancillary; caps at 5 to give the sidebar and
source the vertical space they deserve.
- Clear-on-restart actually works now. Previous attempt deleted the
entire console buffer on start/restart so dapui would create a fresh
one — this worked on `(c)` start (new terminal opens) but broke on
`(R)estart` because the adapter reuses the terminal channel, and
deleting the buffer orphaned the channel (Console went unresponsive).
New approach: KEEP the buffer, briefly toggle modifiable=true, and
call nvim_buf_set_lines with empty content to wipe the scrollback.
The PTY state and output stream stay intact; only the visible lines
are gone. Default `clear_console_on_start = true` again.

Regression fixes from the previous commit:
1. Debug adapter timing out / general slowness — root cause was calling
dapui.setup() on every M.enter() to "refresh layouts". setup is
heavy (tears down windows, re-registers listeners, rebuilds state)
and running it while the adapter handshake is in flight caused
"Debug adapter didn't respond" timeouts. Reverted to one-time setup;
layouts are computed once per nvim session. Trade-off: Console/
sidebar proportions may drift slightly if the terminal is resized
between toggles, but that's vastly preferable to a broken adapter.
2. Console broken / unreachable — clear_console was calling buf_set_lines
on a terminal buffer after dapui had made it a terminal, which leaves
the terminal in an inconsistent state. Kept the config option but
disabled by default (clear_console_on_start = false). Users who want
it can opt in; the feature remains risky on terminal-backed Console
buffers. Better design pending.
3. Bars not spanning full editor width — :topleft split and :botright
split create full-width splits only when no competing vertical
splits exist. dapui's sidebar creates a full-height vertical split
AFTER our bars, which squeezes the bars into the non-sidebar column.
Added force_bars_full_width() which runs `wincmd K` (on sbar) and
`wincmd J` (on cbar) AFTER dapui.open(). These commands re-layout
the window tree with the bar window spanning full editor width,
pushing sidebar + source + tray into the middle rows.

Cluster of UX refinements + one real bug:
Bar chrome:
- Shrunk both bars from 3 rows to 2 rows. dapui's own pane borders act
as the visual separation between the bar and the main content area,
so the inner-facing separator lines on each bar were redundant.
Top bar: sep / content (no bottom line)
Bottom bar: content / sep (no top line)
- Sidebar/Console sizing recalculated: 2-row bars instead of 3 frees
up 2 extra rows for content.
Smarter legend:
- (R)estart is now conditionally rendered — only shown when a dap
session is active. When there's no session, "restart" is meaningless
(there's nothing to restart), so the button hides and the remaining
controls re-center around the smaller set.
Console clear on start/restart:
- New config.opts.clear_console_on_start (default true). Fires on
dap.listeners.before.event_initialized — wipes the Console buffer
so output from a previous run doesn't linger when a new session
begins.
Registers default-collapsed:
- dapui's own scopes component auto-collapses any scope the adapter
marks `expensive = true` (see dapui/components/scopes.lua:22-24).
codelldb (Rust/C++) doesn't mark Registers expensive even though it
dumps hundreds of entries. We intercept the scopes response via
dap.listeners.before.scopes and inject `expensive = true` on any
scope name in config.opts.collapsed_scopes (default `{"Registers"}`).
Reuses dapui's existing collapse mechanism, so no monkey-patching.
Re-entry layout fix:
- The Console "balloon" bug on second ,dd toggle was dapui caching
first-call layout dimensions. ensure_dapui() now re-runs dapui.setup
with freshly computed layouts on EVERY M.enter, so the 25% / 25% /
25% / 25% sidebar split and 15%-of-available Console all recompute
against current terminal + current bar heights.
- Bars are now opened BEFORE dapui.open() so dapui's layout algorithm
sees the reduced available space from the start rather than computing
against full screen and then getting squished.

UX refinement per design feedback:
- Bar is now 3 rows tall: ─ top separator, content row, ─ bottom separator.
The separator chars were invisible before because TurboDebugBarSeparator
linked to WinSeparator (muted in most themes). Switched to FloatBorder.
- Bottom tray default shrunk 12→9 rows so the 3-row bar doesn't overlap
REPL/Console. Net vertical footprint unchanged (12 tray = 9 tray + 3 bar).
- Action labels now teach the keyboard shortcut inline:
▶️ (c)ontinue ⏭️ (s)tep ⬇️ (d)escend ⬆️ (r)eturn
🔄 (R)estart 🛑 (q)uit ❓ (?)help
The (k) letter is highlighted with TurboDebugBarKey → Special so the
shortcut pops. The entire label is a click zone.
- help_on_enter default flipped true → false. The (?)help label in the bar
is always visible, so new users discover help via the bar instead of an
auto-popup on every debug-mode entry.
- No top bar added. The source file winbar already shows 🐛 DEBUG · <file>,
so a second chrome row would just duplicate context and eat screen space.

Addresses live-feedback issues that persisted after v3:
- Control bar now uses buffer content + extmarks instead of winbar —
winbar doesn't render in minimal-style floats, which is why the bar
was empty. Two rows: ─ separator on top, state chip + controls below.
Click dispatch via buffer-local <LeftMouse> keymap + cursor-column
lookup against a zones table.
- Bar auto-refreshes on every dap event (initialized/stopped/continued/
terminated/exited) so the READY/RUNNING/PAUSED chip and dap.status()
text stay live.
- Colorful emoji throughout for instant recognition:
Signs: 🔴 BP, 🟡 conditional, ⭕ rejected, 👉 stopped, 📝 logpoint
Titles: 🔎 Scopes, 👁️ Watches, 📚 Call Stack, 🔴 Breakpoints,
💻 Console, 💬 REPL
Badge: 🐛 DEBUG · <file>
Controls: ▶️⏭️⬇️⬆️🔄🛑❌
- Modal key install no longer skips buffers that already have entries —
every BufEnter/FileType force-reinstalls the keymaps so dapui's own
render pass can't leave them in a broken state.
- IP sign leak fixed: clear_ip() now unplaces lingering DapStopped signs
via sign_getplaced + sign_unplace, so restart no longer leaves a stale
👉 in the gutter of the previously-paused line.
- IP reason text (STEP/BREAKPOINT/EXCEPTION) now uses bold + reverse for
an inverted-color badge that really demands attention.
- dapui.expand_lines = false — this was spawning a cursor-pinned float
when a line was wider than its pane, causing the "hover text bleeds
across the screen" bug. With wrap+breakindent inside the pane, the
hover-float is redundant and destructive.
- Control-bar buffer is marked filetype=TurboDebugBar and explicitly
skipped by the modal key installer, so clicking a button doesn't
accidentally fire modal actions.

Major v3 fixes driven by live-debugging feedback:
- Control bar: replace vim.o.statusline override (lualine fights it) with
a 1-row floating window pinned above the statusline. Shows state chip
(READY/RUNNING/PAUSED) + seven clickable Codicon controls + dap.status().
Survives resize via VimResized autocmd. Fully independent of lualine.
- Console refresh: trailing-edge throttle at config.console_refresh_ms
(default 50ms = 20 Hz ceiling). Targets console windows via nvim_win_call
+ redraw! to avoid screen-cache miss. Chatty programs can't DOS the editor.
- Modal keys in dapui panes: install synchronously on FileType (drop inner
vim.schedule); all modal keys get nowait=true (was continue-only) so
single-key presses aren't swallowed by <leader>d* prefix matching.
- Wrap in dapui panes: wrap=true + breakindent + showbreak=" ↳ " so long
register values stay visible inside the pane without bleeding into the
source window. Safety valve at config.max_value_width (default 2000,
set 0 to disable) truncates only pathological multi-KB dumps with "…".
- Smart q: context-aware terminate. If a session is running, q calls
dap.terminate() and stays in debug mode (so user can read the console
postmortem). If no session, q exits debug mode. Removes quit_exits_mode.
- Icons: full Nerd Font Codicon set for signs, control bar buttons, pane
titles, and debug badge. 👈 emoji in the paused-line vtext pairs with
👉 in the gutter — fingers literally point at the paused line from both
sides.

Rename from tiny-debugger to turbo-debug — inspired by Turbo Pascal,
the first IDE with a real visual debugger. This thing isn't tiny,
it's turbo charged.
CHANGELOG for 0.1.0:
Features:
- Zero-config debugging — one line install, everything works
- Modal keybindings (c/s/d/r/q/x/X/D/W/K/E/R/?), active only
during debug mode, cleanly removed on exit
- Persistent breakpoints via persistent-breakpoints.nvim
- Inline virtual text — variable values in source code
- Hover (K), watch (W), REPL eval (E) from the code window
- Help splash (3s auto-dismiss) + manual help (?)
- Debug mode chrome — winbar indicator, cursor highlight
- dapui integration — controls toolbar, labeled panels
- which-key support — <leader>d debug group auto-registered
- quit_exits_mode option
Adapters (12 languages):
- Python (debugpy + venv detection)
- Rust (codelldb + cargo build + vim.ui.select picker)
- Go (delve), C/C++/Swift (codelldb)
- JavaScript/TypeScript (js-debug-adapter)
- C# (netcoredbg), Java, Kotlin, PHP, Ruby, Lua (osv)
Keybindings:
- <leader>dd — toggle debug mode
- <leader>dx / <leader>dX / <leader>dD — breakpoints (always)
- c s d r C x X D W K E q R ? — modal (debug mode only)
