a code review TUI with vim keybindings

A code review TUI with vim keybindings. Export to GitHub, GitLab, or clipboard.

• GitHub-style continuous diff in the terminal. Scroll through every changed file in one stream.
• PR-style comments at the line, range, file, and review level.
• Review tracking at file or hunk granularity, persisted across sessions.
• Three export targets: push a real review to GitHub or GitLab, copy structured markdown to your clipboard, or pipe to stdout.
• Works with git, jj, and mercurial. Reviews uncommitted changes, commit ranges, or any GitHub PR or GitLab MR.

curl -fsSL tuicr.dev/install.sh | sh
# or
brew install agavra/tap/tuicr

# Cargo
cargo install tuicr

# Mise
mise use github:agavra/tuicr

# Nix
nix run github:agavra/tuicr

git clone https://github.com/agavra/tuicr.git
cd tuicr
cargo install --path .

Update the active installation with one command:

tuicr update
tuicr update 0.18.0 # Install a known-good version

tuicr update uses Homebrew, Cargo, Mise, or a Nix profile when that manager owns the executable. Install-script and manually downloaded binaries update in place from the matching GitHub release asset after SHA-256 verification. Exact-version installs support Cargo and direct binaries; use the package manager's pinning workflow for Homebrew, Mise, or Nix. A nix run invocation is temporary rather than installed; rerun it to use the current flake, or use nix profile install github:agavra/tuicr for an installation that tuicr update can upgrade.

tuicr                       # Pick from a commit selector
tuicr tui                   # Same TUI, explicit subcommand
tuicr -w                    # Uncommitted changes (skip selector)
tuicr -r main..HEAD         # Commit range
tuicr pr 125                # GitHub PR
tuicr mr 125                # GitLab MR
tuicr tui pr 125            # GitHub PR via explicit TUI subcommand
tuicr tui mr 125            # GitLab MR via explicit TUI subcommand
tuicr --stdout              # Pipe the review to stdout
tuicr review list           # List saved local review sessions
tuicr update                # Update the active installation
tuicr update 0.18.0         # Install a known-good version

Inside tuicr, navigate with j/k, press c to comment, then y to copy the review or :submit to push it to GitHub or GitLab. When opening a GitHub PR or GitLab MR you've reviewed before, tuicr preselects commits newer than your latest submitted review when that metadata is available; commits already covered by that review are marked with ✓ in the inline selector. Auto-detects git, jj, or mercurial.

¹ Lumen has j/k navigation but no broader vim model (visual mode, {N}G, Ctrl-d/Ctrl-u, etc.).

² gh pr review posts approve/comment/request-changes at the review level only. No inline line comments.

When you're done reviewing, send your comments wherever the work continues.

:submit opens a picker for Comment, Approve, Request changes, or Draft. Inline comments land on the right lines as a real PR review. Review-level comments become the review summary. Requires gh authenticated to the repo.

:submit offers Comment, Approve, or Request changes on a GitLab MR. Inline comments post as discussion notes. Review-level comments become the summary. Requires glab authenticated to the host. Request changes needs your account to be an assigned reviewer. Only Draft is GitHub-only here. See docs/GITLAB.md for setup, self-hosted instances, and troubleshooting.

y or :clip copies a structured markdown block to your clipboard. Each comment has a number and a file/line anchor:

I reviewed your code and have the following comments. Please address them.

1. `src/auth.rs` - Consider adding unit tests
2. `src/auth.rs:42` - Magic number should be a named constant
3. `src/auth.rs:50-55` - This block could be refactored

Paste it back to any coding agent (Claude, Codex, Cursor, etc).

For an agent-driven workflow where your agent opens tuicr in a tmux, Zellij, or Herdr split pane, see skills/tuicr/SKILL.md.

Run with --stdout to pipe the markdown to another process:

tuicr --stdout > review.md
tuicr --stdout | pbcopy

tuicr review exposes saved sessions without opening the TUI. It can list sessions, add comments, and print stored comments for agent and script integrations. See docs/REVIEW_CLI.md.

The TUI creates a persisted session file when a review target becomes active, so collaborative tools can add comments immediately. Empty auto-created session files are removed when the TUI exits. tuicr review list marks currently open TUI sessions with "active": true.

tuicr also exposes a Rust library API for tools that want to build on top of its persisted review sessions. ReviewStore can list sessions for a checkout, load a session, and add review, file, line, or range comments using the same insertion primitive as the TUI.

use tuicr::{AddCommentRequest, CommentTarget, CommentType, LineSide, ReviewStore};

let store = ReviewStore::new();
let sessions = store.list_sessions_for_repo("/path/to/repo")?;
let session = &sessions[0].session_ref;

store.add_comment(
    session,
    AddCommentRequest {
        target: CommentTarget::Line {
            path: "src/main.rs".into(),
            line: 42,
            side: LineSide::New,
        },
        content: "Handle the empty case here.".into(),
        comment_type: CommentType::from_id("issue"),
    },
)?;

Path: ~/.config/tuicr/config.toml on Linux/macOS, %APPDATA%\tuicr\config.toml on Windows.

theme = "catppuccin-mocha"
diff_view = "side-by-side"   # or "unified"
ignore_whitespace = false    # ignore all whitespace in local VCS diffs
appearance = "system"        # or "dark" / "light"
mouse = true
leader = ";"                  # configurable prefix for leader shortcuts
comment_vim = false           # vim modal editing in the review comment box
review_watch_interval_ms = 1000 # set to 0 to disable persisted-review polling

[[comment_types]]
id = "issue"
color = "red"
definition = "must fix before merge"

Bundled themes: dark, light, ayu-light, ayu-mirage, onedark, github-light, github-dark, catppuccin-latte, catppuccin-frappe, catppuccin-macchiato, catppuccin-mocha, everforest-dark, everforest-light, gruvbox-dark, gruvbox-light, nord-dark, nord-light, nord-dark-high-contrast, nord-light-high-contrast, solarized-light, solarized-dark, tokyo-night-storm, tokyo-night-day.

Local themes: set theme = "my-theme" or run tuicr --theme my-theme, then create ~/.config/tuicr/themes/my-theme.toml on Linux/macOS or %APPDATA%\tuicr\themes\my-theme.toml on Windows. Local themes may reference a local syntax_theme = "my-syntax.tmTheme" file for syntax highlighting. A ready-to-copy example lives at examples/tuicr-teal.toml with its matching examples/tuicr-teal-syntax.tmTheme syntax theme.

Full options, theme resolution precedence, comment_types semantics, and .tuicrignore rules in docs/CONFIG.md.

Thanks to the folks below for keeping tuicr development going, it means a lot to have the work I'm doing here appreciated!
