# Multi Git Frontend A lightweight read-only web frontend for browsing multiple git repositories, built with [CppCMS](http://cppcms.com/), libgit2, C++17 and CMake. It scans a directory for git repositories and serves each one as a sub-path, showing the file tree, individual files (with syntax highlighting), raw content, blame, commit log and arbitrary objects. Only the **default branch** and **committed content** are shown — the working directory is never read. ## Routes | URL | Shows | |-----|-------| | `/` | Front page | | `/repos` | List of repositories | | `/repos/<name>` | Repository home (rendered README) | | `/repos/<name>/tree/` | File tree at the root | | `/repos/<name>/tree/<path>` | Sub-directory listing, or a file with highlighting | | `/repos/<name>/raw/<path>` | Raw file content | | `/repos/<name>/blame/<path>` | Per-line blame | | `/repos/<name>/log/` | Commit log | | `/repos/<name>/commit/<hash>` | Commit details: message, changed files and the diff | | `/repos/<name>/commit/<hash>.patch` | Raw unified patch (`text/plain`) | | `/repos/<name>/tags/` | List of tags | | `/repos/<name>/tags/<tag>` | Tag details (target commit, message) | | `/repos/<name>/object/<hash>` | Inspect a blob, tree, commit or tag | Every page accepts `?id=<hash>` to view at a specific commit instead of the default branch HEAD. ## Configuration `config.json` controls the HTTP service and the repository root: - `service.port` — listening port (default `11000`). - `git.root` — directory to scan for repositories. Overridden by the `GIT_ROOT` environment variable; falls back to `$HOME/git`. - `git.static_root` — directory containing the bundled CSS/JS assets. - `SHOW_EMAILS` (env) — author/committer email addresses are hidden by default; set `SHOW_EMAILS=1` to show them. Syntax highlighting (highlight.js) and markdown (marked.js) are rendered client-side from vendored assets in `static/`, so the server needs no extra runtime dependencies. Markdown files (`.md`, `.markdown`) and the repo README are rendered in the normal file view; `raw` and `blame` always show the source. ## Build from source Requires CppCMS (with `cppcms_tmpl_cc`), libgit2, CMake and a C++17 compiler. ```sh cmake -S . -B build -DCMAKE_BUILD_TYPE=Release cmake --build build -j ./build/git_frontend -c config.json ``` Then open <http://localhost:11000/>. ## Docker The image builds CppCMS from source (it is not packaged in Ubuntu) and bundles everything. Mount a directory of repositories at `/srv/git`: ```sh docker build -t git_frontend . docker run --rm -p 11000:11000 -v "$HOME/git:/srv/git:ro" git_frontend ``` To reveal email addresses, pass the environment variable: ```sh docker run --rm -p 11000:11000 -e SHOW_EMAILS=1 -v "$HOME/git:/srv/git:ro" git_frontend ``` ## Layout ``` src/ main.cpp Service bootstrap and repo-root resolution application.* CppCMS application: URL routing and request handlers git_repo.* libgit2 wrapper (commits, trees, blobs, blame, log, objects) repo_scanner.* Discovers repositories under the root content.h Typed data passed to the templates util.* Small helpers (oid validation, sizes, time, paths) templates/skin.tmpl CppCMS template skin (compiled to views.cpp at build time) static/ style.css, app.js, vendored highlight.js + marked.js ```
