 1 | # Metal Git
 2 | 
 3 | # What's this?
 4 | 
 5 | GUI Git Frontend written in gtk-rs (gtk+ Rust wrapper) and git2-rs (libgit2 Rust wrapper).
 6 | 
 7 | # Caution
 8 | 
 9 | This program is now in experimental stage. It may destroy your files or repositories, so use carefully.
10 | 
11 | # How to build?
12 | 
13 | Install build dependencies at first. This program requires gtk+3 and libgit2.
14 | 
15 | In Ubuntu 14.04 / 16.04, run this:
16 | 
17 | ```
18 | $ sudo apt install libgtk-3-dev libgit2-dev cmake
19 | ```
20 | 
21 | If build dependencies are properly installed, cargo should succeed.
22 | 
23 | ```
24 | $ cargo run
25 | ```
26 | 
27 | This program opens a git repository at the working directory.
28 | 
29 | If you want a binary, use cargo build.
30 | 
31 | ```
32 | $ cargo build --release
33 | $ sudo cp target/release/metal-git /usr/local/bin
34 | ```
