# GitPad

A lightweight git web interface with:

* **editing support** (create, edit, move and remove files)
* **Markdown rendering** (for files named `*.md`, requires the `md` feature)
* a **multi-user mode** (each user gets their own private branch)

You can install GitPad with:

```
$ cargo install gitpad
```

GitPad needs to be started from inside of a bare Git repository.
For example:

```
$ git init --bare example.git
$ cd example.git/
$ gitpad
Listening on http://127.0.0.1:8000
```

By default GitPad is in single-user mode, serving the branch pointed to by `HEAD`.

## Multi-user mode

Multi-user mode requires you to set up a reverse-proxy that authenticates users
and sets the `Username` header. Every user gets their own private Git branch,
named exactly like their username and served under `/~{username}`.

The simplest authentication mechanism is HTTP Basic Auth.  With NGINX a
reverse-proxy could be configured as follows:

```nginx
server {
    listen 80;
    listen [::]:80;

    server_name notes.localhost;
    client_max_body_size 5M;

    location / {
        auth_basic 'Restricted';
        auth_basic_user_file /etc/nginx/gitpad_passwd;
        proxy_set_header Username $remote_user;

        proxy_pass http://localhost:8000;

        # Or if you start GitPad with --socket /srv/sockets/gitpad.sock
        # proxy_pass http://unix:/srv/sockets/gitpad.sock;
    }
}
```

For instructions on how to create the `auth_basic_user_file`,
refer to the [NGINX documentation](https://docs.nginx.com/nginx/admin-guide/security-controls/configuring-http-basic-authentication/).

Once you have set this up start GitPad in multi-user mode by running it with the
`-m` flag.

## Configuring committer identities

In single-user mode GitPad just uses the
committer identity from your git config.

In multi-user mode GitPad defaults to `{username} <{username}@localhost.invalid>`.
Committer identities can be configured by creating a `users.toml` file in the
`gitpad` branch, with sections like the following:

```toml
[johndoe]
name = "John Doe"
email = "john@example.com"
```
