TUI Guide

The CLI includes an interactive Terminal UI (TUI) for browsing and solving problems without typing full commands.

Launch

leetcode

Launch behavior:

No arguments + interactive terminal: starts TUI.
No arguments + non-interactive output (piped/CI): prints CLI help.
With arguments: runs normal command mode.

Use these from the TUI:

j/k or up/down: move cursor or scroll.
Enter: open/select.
Esc: go back or close current drawer/panel.
?: open/close keyboard help.
Ctrl+C: quit immediately.
q: quit from Home.

Screen Map

Home: entry point to list, daily/random, bookmarks, timer, stats, workspace, config, changelog, help.
List: filter and search problems, then open one with Enter.
Problem: full statement view + bottom action bar.
Workspace: manage and switch workspaces, edit workspace properties.
Config: edit active workspace settings.
Stats / Timer / Changelog / Help: read-only data and navigation views.

Problem Screen (Drawer Model)

Problem view now uses a single-column layout:

Full-width statement content.
Unified bottom drawer for action output.
One action hint row (no duplicate hint bars).

Action keys:

p: pick file
t: run tests
s: submit
h: hints
H or S: submissions
V, v, or w: snapshots
b: bookmark toggle
n: view note
e: edit note

Drawer behavior:

Tab: toggle focus between statement body and drawer.
j/k or up/down: scroll focused region.
Esc: close drawer first; press again to leave problem screen.

Workspace and Config Editing

Both screens use buffered editing:

Move/select fields with arrows or j/k.
Enter: start edit or save.
Esc: cancel current edit or go back.
Tab / h / l: switch pane focus.

Terminal Cleanup Guarantees

When leaving TUI (quit or opening external editor), the app restores terminal state:

exits alternate screen
restores cursor visibility
disables raw mode
applies ANSI reset guards to avoid style residue

If your terminal still looks wrong after an interrupted session, run:
