Minimal Git GUI for Linux (Ubuntu), focused on branch history and merge operations. Built with Qt 6 and the system git CLI.

• CMake 3.16+
• C++17 compiler
• Qt 6 Widgets (qt6-base-dev on Ubuntu)
• Git 2.34+
• macOS/Linux: POSIX PTY for the built-in terminal (bundled libvterm)

sudo apt install build-essential cmake git qt6-base-dev

brew install qt@6 cmake git
cmake -B build -DCMAKE_PREFIX_PATH="$(brew --prefix qt@6)"

cmake -B build -DCMAKE_BUILD_TYPE=Debug
cmake --build build
./build/src/git_view

On macOS, pass CMAKE_PREFIX_PATH if Qt is not found automatically (see above).

The bottom panel is a real interactive terminal (PTY + VT100 emulator): you can run git, vim, htop, pagers, and full-screen programs. Working directory is the repository root. Press Ctrl+` to focus it.

cmake -B build -DGIT_VIEW_BUILD_TESTS=ON
cmake --build build
ctest --test-dir build --output-on-failure

Create a sample repository for manual testing:

./tests/fixtures/create_fixture_repo.sh /tmp/git_view-fixture
./build/src/git_view
# File → Open repository → /tmp/git_view-fixture

git_view --help
git_view /path/to/repo
git_view --repo /path/to/repo --action working-changes
git_view --action file-history --file src/main.cpp /path/to/repo
git_view --action file-diff --diff-scope staged --file README.md /path/to/repo

Actions: open, working-changes, file-history, file-diff, commit, log.

TortoiseGit-style context menu for git repositories:

chmod +x integrations/install-nautilus-integration.sh
./integrations/install-nautilus-integration.sh /path/to/git_view
nautilus -q

• Scripts → GitView — works without extra packages.
• Direct context menu items — install python3-nautilus, then re-run the installer.

Configuration: ~/.config/git_view/integration.conf (GIT_VIEW_BIN).

• Open local repository, list branches (local and remote)
• Commit history with branch graph (lane layout) and metadata columns
• Commit details panel: file list + per-file diff (git show, syntax highlighting)
• Working tree tab: uncommitted/staged changes (git status, git diff)
• Commit working tree changes (git add -A, git commit) via dialog
• Create branches (git branch / git checkout -b, optional base ref)
• Merge branch into current (optional --no-ff, conflict file list, abort merge)
• Load more commits (pagination in pages of 500)
