feat(tui): powerline separators, chip styles, and sidebar button customization - #10469
Conversation
…omization
Status bar: status_bar.left_separator/right_separator draw powerline
transitions between segments (separator foreground from the previous
segment's background, background from the next), and
status_bar.screens_style wraps the active screen chip in pill or slant
caps. tabs.style gives solid tab chips the same pill/slant caps, cap
cells participating in layout, scrolling, and hit rects.
Sidebar: pinned view actions accept object entries with a label override
({action, label}), command:<id> entries that pin a user command as a
button, and actions_position: top mounts the buttons under the header.
sidebar.row_height 1 drops the subtitle line, sidebar.row_gap 0 removes
entry padding, sidebar.rail_glyph replaces or removes the active-row
accent glyph, sidebar.workspace_label templates rows with {index}/{name},
and theme.sidebar_fg/sidebar_selected_fg recolor the rows. User commands
resolve before sidebar views so buttons can reference them; chords still
bind after keys overrides.
📝 WalkthroughWalkthroughThe PR adds configurable sidebar actions, workspace labels, rail metrics, active-row styling, status-bar separators, screen-chip styles, and tab-chip caps. Configuration resolution supports command references and deferred chord binding. ChangesConfigurable sidebar and status UI

There was a problem hiding this comment.
When actions_position: "top" is configured on a multi-level view such as workspaces → agents, the setting is resolved here but has no effect: draw_projection still calls the bottom-only rail::viewport in ui/sidebar.rs, while only the legacy one-level workspace renderer uses viewport_positioned. Consequently, the documented option silently renders projection actions at the bottom; pass the resolved position through the projection renderer as well.

There was a problem hiding this comment.
With sidebar.view: "files", these new theme settings are ignored: draw_files in ui/sidebar.rs still constructs unselected rows from Style::default() and selected rows from chrome.sidebar_selected_fg, whereas only RailPalette reads theme.sidebar_fg and theme.sidebar_selected_fg. Users therefore see the documented sidebar foreground customization in workspace/machine rails but not in the built-in file sidebar; apply the overrides in draw_files too.
Useful? React with 👍 / 👎.
Greptile SummaryThis PR adds configurable powerline/chip rendering, customizable plus-button actions and menus, and denser, themed sidebar rows. It also introduces per-view sidebar action placement, but the projection renderer still does not honor top placement.
Confidence Score: 4/5The PR is not yet safe to merge because multi-level and non-legacy sidebar views still ignore top action placement. The projection renderer continues to call the viewport wrapper that hardcodes bottom placement, so the previously reported configuration failure remains reachable despite the workspace-specific fix.

When a multi-level or non-legacy projection view sets actions_position to "top", configuration stores the value but draw_projection uses the bottom-only rail::viewport, causing its action buttons to remain pinned at the bottom instead of rendering beneath the header.

📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value
Template expansion is safe but stylistically diverges from the file's own one-pass pattern.
workspace_button_label performs two sequential, non-overlapping .replace() calls for {index} and {name}. Because str::replace scans only the original haystack per call and {index} is substituted before {name}, a workspace name containing literal {index} text cannot be rescanned, so this is not currently exploitable. expand_status_tokens in this same file documents and implements an explicit single left-to-right pass specifically to prevent an inserted value from being rescanned by a later token. Reusing that pattern here would make the two implementations consistent and remove the need to reason case-by-case about replace-order safety if a third token is ever added.

Register hit rectangles for all configured entry rows.
RailMetrics::height can exceed two. rail::entry renders every configured row. Lines 281, 373, 662, and 694 register hit rectangles for only the first two rows. Clicks on later rows do not select the displayed machine, tab, or workspace.
Replace each pair of one-row hit rectangles with one rectangle whose height is metrics.height. Add a regression test with row_height: 3.

Do not draw the drag marker over an entry when row_gap is zero.
The configuration accepts row_gap: 0. For a dense rail, marker_row resolves to an entry row. The ─ marker then overwrites the first workspace row or the preceding workspace subtitle.
Draw the marker only in a gap row. Use a non-destructive visual state when no gap exists.

When sidebar.row_height or sidebar.row_gap differs from the default, rendering adopts this computed stride but the interaction geometry does not: handle_scroll_with_admission still adjusts machine/workspace/tab offsets by 3, rail_page_size still divides by 3, and workspace_drop_target_at still assumes three-row entries. For example, with row_height: 2 and row_gap: 0, one wheel notch produces an odd offset, leaving a blank row because partially visible entries are rejected, while workspace drag targets no longer align with the rendered rows. Route these consumers through the configured RailMetrics as well.
Useful? React with 👍 / 👎.
tabs.plus and status_bar.screens_plus customize the two + buttons: label text, a left-click action override (any action name or command:<id>), and a right-click context menu whose entries use the sidebar action grammar, labels included. Menu entries dispatch through the new MenuAction::RunConfigured variant, which routes into the shared run_action_for_pane path, so user commands and every catalog action work from a plus menu; the variant is registered in the menu inventory.

Add test coverage for the new configurable plus-button dispatch.
This change adds MenuAction::RunConfigured, plus_menu_items, and wires configured actions into Hit::NewTab, Hit::NewScreen, and their right-click menus. No test in this file exercises a configured tabs.plus.action or status_bar.screens_plus.action overriding the default new-tab or new-screen behavior, or a right-click menu populated from plus_menu_items. This surface lets users run arbitrary configured actions from a click that previously always created a tab or screen. Add at least one test that configures a plus-button action and asserts the click runs that action instead of the default, and one test that verifies the right-click menu lists the configured items.

Represent the RunConfigured route as a referenced action.
RunConfigured executes its embedded Action, but menu_action_metadata() uses a fixed route string and the schema accepts only strings. A later Action route change can therefore leave the checker and inventory stale while validation passes. Add a structured referenced-action route and resolve it through action_metadata() in cmux-tui/scripts/check-spec-inventory.py; update cmux-tui/spec/inventory.json and its schema accordingly.

There was a problem hiding this comment.
When a one-level workspace view sets actions_position: "top", this changes only the rendered viewport: workspace_rail_targets() still orders every workspace and recoverable workspace before the actions. Consequently, keyboard navigation does not follow the visual order—Home selects the first workspace rather than the top action, and Down from the last workspace jumps upward to an action. Build the navigation target order from the configured position as well.

There was a problem hiding this comment.
With sidebar.workspace_label configured, only live rows in the legacy workspace renderer pass through workspace_button_label; recoverable workspace rows below them still render workspace.name, and multi-level projection views render row.name directly. This produces mixed labels in the same rail and makes the documented template ineffective for workspace nodes in projection views. Apply the template wherever a workspace resource row is rendered.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Fix menu_action_prepares_pty_release so it does not block session-independent configured actions.
activate_menu gates every MenuAction on menu_action_prepares_pty_release(action) before dispatch. That function returns true for every MenuAction::RunConfigured { .. }, because RunConfigured is not in its exclusion list.
action_prepares_pty_release(Action) excludes ShowShortcuts, RenameWorkspace, RenameScreen, RenameTab, NewWorkspace, NewPaneRight, ScrollUp, ScrollDown, BrowserEditUrl, and SendPrefix from needing prepare_pty_input_before_mutation(). run_action_for_pane_with_prefix uses that Action-level check, so these actions run fine from a keyboard shortcut even when session_available() is false.
A + button right-click menu item built by plus_menu_items wraps its configured Action in MenuAction::RunConfigured. Because menu_action_prepares_pty_release treats RunConfigured as always needing an active session, clicking a configured menu entry for one of the excluded actions (for example a ShowShortcuts or RenameWorkspace entry) fails with "No active session" and never reaches run_action_for_pane whenever session_available() is false, such as during a machine switch or reconnect. The same action bound to a keyboard shortcut still works in that state.
Left-click dispatch of tabs.plus.action and status_bar.screens_plus.action (Hit::NewTab, Hit::NewScreen) calls run_action_for_pane directly and is not affected; only the right-click menu path through activate_menu is broken.

…glyph The status bar borrows its separators and scans the bounded segment slices in place instead of cloning strings and collecting vectors on every draw. Workspace row labels return a borrowed name under the default template, allocating only when a custom template expands. sidebar.rail_glyph now requires exactly one single-width character (or none), matching the single cell the renderer reserves.
