tuicr

tuicr

A code review TUI with vim keybindings. Export to GitHub, GitLab, Gitea, Bitbucket, Azure DevOps, Gerrit, or clipboard.

[!TIP] Pronounced "tweaker".

What it does

• 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, GitLab, Gitea, Bitbucket, Azure DevOps, or Gerrit, 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, GitLab MR, Gitea PR, Bitbucket PR, Azure DevOps PR, or Gerrit change.

Install

curl -fsSL tuicr.dev/install.sh | sh
# or
brew install tuicr
# or
sudo pacman -S tuicr

# Cargo
cargo install tuicr

# Mise
mise use github:agavra/tuicr

# Nix
nix run github:agavra/tuicr

Pre-built binaries: GitHub Releases. Linux releases include dynamically linked GNU and static musl variants.

From source:

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.

Quick start

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 --file f.md --line 42 # Annotate a file, starting at line 42
tuicr pr 125                # GitHub, Gitea, Bitbucket, or Azure DevOps PR, or Gerrit change
tuicr pr 125 --remote up    # Use a named Git remote's fetch URL
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

Every flag, environment variable, and exit code in docs/CLI.md.

The default Git backend detects renames using a 50% similarity threshold and honors Git's diff.renames and diff.renameLimit settings. Working-tree reviews include untracked destinations in rename detection, so a move can appear as R before staging.

Inside tuicr, navigate with j/k, press c to comment, then y to copy the review or :submit to push it to GitHub, GitLab, Gitea, Bitbucket, Azure DevOps, or Gerrit. When reopening a pull request 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. (Bitbucket does not record which commit an approval covered, so that preselection does not apply there.) Use :summary during a review to show every pending local-draft comment. The summary replaces the diff while leaving the file sidebar visible when it is open. The first comment is selected when the view opens; use j/k to select the next or previous comment, and the view scrolls automatically to keep it visible. Press Enter to jump to the selected comment in the continuous diff, leaving single-file view if necessary, or Esc to return to the diff. If its file or hunk is already marked reviewed, tuicr reveals the target without clearing that reviewed state. Press dd to delete the selected local draft, even if its original line or file is absent from this diff. Return with Esc and use :w to save the deletion, as with diff-view deletion. Auto-detects git, jj, or mercurial. SHA-256 Git repositories automatically use the Git CLI backend, including when reviewing root commits; ordinary SHA-1 repositories still default to libgit2.

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.

Export your review

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

To GitHub

: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.

To GitLab

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

To Gitea

:submit offers Comment, Approve, Request changes, or Draft on a Gitea pull request. Inline comments post as review comments and review-level comments become the summary, all in one request. Requires tea with a login for the instance (tea logins add). Multi-line comments collapse to their last line — Gitea has no range form. See docs/GITEA.md for setup, self-hosted detection, and limitations.

To Bitbucket

:submit offers Comment or Approve on a Bitbucket Cloud PR. Inline comments post as inline PR comments, multi-line ranges included; review-level comments become general PR comments. Requires bkt authenticated to bitbucket.org. Request changes and Draft are not supported yet, and Bitbucket Data Center is out of scope. See docs/BITBUCKET.md for setup, required token scopes, and troubleshooting.

To Azure DevOps

:submit offers Comment, Approve, or Request changes on an Azure DevOps PR. Inline comments post as PR comment threads; Approve/Request changes also cast a reviewer vote. Auth is a Personal Access Token in AZURE_DEVOPS_EXT_PAT (preferred — works with enterprise tenants), falling back to az login via the Azure CLI. Run tuicr from a local clone of the repo — Azure exposes no unified-diff API, so the diff is built with git diff base...head. See docs/AZURE.md for setup, supported URL forms, and MVP limitations.

To Gerrit

:submit offers Comment, Approve, Request changes, or Draft on a Gerrit change. Inline comments post as Gerrit comments (multi-line ranges included) and the review-level comment becomes the change message; Approve votes Code-Review +2 and Request changes votes -1. Draft keeps everything as Gerrit draft comments so you can publish from the web UI; tuicr keeps showing them, marked draft. Auth is your Gerrit HTTP password in GERRIT_USERNAME / GERRIT_PASSWORD. Run tuicr from a local clone — the diff is built with git diff base..head after fetching the change's patch-set ref. See docs/GERRIT.md for setup, detection of self-hosted hosts, and limitations.

To your coding agent

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 cmux, Rex, tmux, Zellij, or Herdr split pane, see skills/tuicr/SKILL.md.

To stdout

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

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

Review session CLI

tuicr review exposes saved sessions without opening the TUI. It can list sessions, add, delete, and clear 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.

Inside the TUI, the review target selector's Sessions tab lists the saved reviews for the current checkout, so you can resume one by picking it instead of retyping the commit range it was opened with. Open it with :sessions or cycle to it with Tab. Press dd to delete the review under the cursor after a confirmation prompt, and a to reveal reviews holding no comments and no reviewed files, which are hidden by default.

Library API

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"),
    },
)?;

Configuration

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
editor = "nvim"               # editor for `e` / `:edit`; overrides $EDITOR
comment_vim = false           # vim modal editing in the review comment box
relative_line_numbers = false # show rendered-row distances in the diff gutter

[[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.
