# cargo-graph

Linux: [![Build Status](https://travis-ci.org/kbknapp/cargo-graph.svg?branch=master)](https://travis-ci.org/kbknapp/cargo-graph)

A `cargo` subcommand for building GraphViz DOT files of dependency graphs. This subcommand was originally based off and inspired by the project [cargo-dot](https://github.com/maxsnew/cargo-dot) by [Max New](https://github.com/maxsnew)

## Demo

Let's say we wanted to build a dependency graph of [cargo-count](https://github.com/kbknapp/cargo-count) but we wanted optional dependencies to use red dashed lines and black boxes, and regular (aka "build") dependencies to use orange lines to green diamonds, one would run the following.

**NOTE:** GraphViz `dot` needs to be installed to produce the .PNG from the dotfile

```
$ cargo graph --optional-line-style dashed --optional-line-color red --optional-shape box --build-shape diamond --build-color green --build-line-color orange > cargo-count.dot
$ dot -Tpng > rainbow-graph.png cargo-count.dot
```

**NOTE:** It's also possible to run `cargo graph [options] | dot [options] > [file]` instead of individual commands

The first command produces a GraphViz DOT file which looks like this:

```
digraph dependencies {
  N0[label="cargo-count",shape=diamond,color=green];
  N1[label="ansi_term",shape=box];
  N2[label="clap",shape=diamond,color=green];
  N3[label="clippy",shape=box];
  N4[label="glob",shape=diamond,color=green];
  N5[label="regex",shape=diamond,color=green];
  N6[label="tabwriter",shape=diamond,color=green];
  N7[label="aho-corasick",shape=diamond,color=green];
  N8[label="memchr",shape=diamond,color=green];
  N9[label="bitflags",shape=diamond,color=green];
  N10[label="strsim",shape=diamond,color=green];
  N11[label="unicode-normalization",shape=diamond,color=green];
  N12[label="libc",shape=diamond,color=green];
  N13[label="regex-syntax",shape=diamond,color=green];
  N14[label="unicode-width",shape=diamond,color=green];
  N0 -> N1[label="",style=dashed,color=red];
  N0 -> N2[label="",color=orange];
  N0 -> N3[label="",style=dashed,color=red];
  N0 -> N4[label="",color=orange];
  N0 -> N5[label="",color=orange];
  N0 -> N6[label="",color=orange];
  N7 -> N8[label="",color=orange];
  N2 -> N1[label="",style=dashed,color=red];
  N2 -> N9[label="",color=orange];
  N2 -> N10[label="",color=orange];
  N3 -> N11[label="",color=orange];
  N8 -> N12[label="",color=orange];
  N5 -> N7[label="",color=orange];
  N5 -> N8[label="",color=orange];
  N5 -> N13[label="",color=orange];
  N6 -> N14[label="",color=orange];
}
```

The second command produces a PNG image of the graph which looks like:

Now, *why* someone would do that to a graph is a different story...but it's possible :)

## Installing

`cargo-graph` can be installed with `cargo install`

```
$ cargo install cargo-graph
```

This may require a nightly version of `cargo` if you get an error about the `install` command not being found. You may also compile and install the traditional way by following the instructions below.

## Compiling

Follow these instructions to compile `cargo-count`, then skip down to Installation.

1. Ensure you have current version of `cargo` and [Rust](https://www.rust-lang.org) installed
 2. Clone the project `$ git clone https://github.com/kbknapp/cargo-graph && cd cargo-graph`
 3. Build the project `$ cargo build --release` (**NOTE:** There is a large performance difference when compiling without optimizations, so I recommend always using `--release` to enable to them)
 4. Once complete, the binary will be located at `target/release/cargo-graph`

## Installation and Usage

All you need to do is place `cargo-graph` somewhere in your `$PATH`. Then run `cargo graph` anywhere in your project directory. For full details see below.

### Linux / OS X

You have two options, place `cargo-graph` into a directory that is already located in your `$PATH` variable (To see which directories those are, open a terminal and type `echo "${PATH//:/\n}"`, the quotation marks are important), or you can add a custom directory to your `$PATH`

**Option 1**
If you have write permission to a directory listed in your `$PATH` or you have root permission (or via `sudo`), simply copy the `cargo-graph` to that directory `# sudo cp cargo-graph/usr/local/bin`

**Option 2**
If you do not have root, `sudo`, or write permission to any directory already in `$PATH` you can create a directory inside your home directory, and add that. Many people use `$HOME/.bin` to keep it hidden (and not clutter your home directory), or `$HOME/bin` if you want it to be always visible. Here is an example to make the directory, add it to `$PATH`, and copy `cargo-graph` there.

Simply change `bin` to whatever you'd like to name the directory, and `.bashrc` to whatever your shell startup file is (usually `.bashrc`, `.bash_profile`, or `.zshrc`)

```sh
$ mkdir ~/bin
$ echo "export PATH=$PATH:$HOME/bin" >> ~/.bashrc
$ cp cargo-graph~/bin
$ source ~/.bashrc
```

### Windows

On Windows 7/8 you can add directory to the `PATH` variable by opening a command line as an administrator and running

```sh
C:\> setx path "%path%;C:\path\to\cargo-graph\binary"
```

Otherwise, ensure you have the `cargo-graph` binary in the directory which you operating in the command line from, because Windows automatically adds your current directory to PATH (i.e. if you open a command line to `C:\my_project\` to use `cargo-graph` ensure `cargo-graph.exe` is inside that directory as well).

### Options

There are a few options for using `cargo-graph` which should be somewhat self explanatory.
