A cargo subcommand for displaying when Rust dependencies are out of date
## About
`cargo-outdated` is for displaying when dependencies have newer versions available.
## How it works
The functionality of `cargo-outdated` largely depends on the `cargo` builtin command `cargo update`.
To retrieve the list of available SemVer compatible dependencies, `cargo-outdated` firstly creates a temporary workspace, then executes `cargo update` against it, finally compares the temporary dependency tree with the original one.
Similarly, to check the latest dependencies, `cargo-outdated` replaces the SemVer requirements of *direct* dependencies with wildcards then goes through the same process.
## Demo
Once installed (see below) running `cargo outdated` in a project directory looks like the following:
```
$ cargo outdated
Name Project Compat Latest Kind Platform
---- ------- ------ ------ ---- --------
clap 2.20.0 2.20.5 2.26.0 Normal ---
clap->bitflags 0.7.0 --- 0.9.1 Normal ---
clap->libc 0.2.18 0.2.29 Removed Normal ---
clap->term_size 0.2.1 0.2.3 0.3.0 Normal ---
clap->vec_map 0.6.0 --- 0.8.0 Normal ---
num_cpus 1.6.0 --- 1.6.2 Development ---
num_cpus->libc 0.2.18 0.2.29 0.2.29 Normal ---
pkg-config 0.3.8 0.3.9 0.3.9 Build ---
term 0.4.5 --- 0.4.6 Normal ---
term_size->libc 0.2.18 0.2.29 0.2.29 Normal cfg(not(target_os = "windows"))
```
## Installing
`cargo-outdated` can be installed with `cargo install`
```
$ cargo install cargo-outdated
```
## Compiling
Follow these instructions to compile `cargo-outdated`, then skip down to Installation.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 Clone the project `$ git clone https://github.com/kbknapp/cargo-outdated && cd cargo-outdated`
3. Build the project `$ cargo build --release`
4. Once complete, the binary will be located at `target/release/cargo-outdated`
## Installation and Usage
All you need to do is place `cargo-outdated` somewhere in your `$PATH`. Then run `cargo outdated` anywhere in your project directory. For full details see below.
### Linux / OS X
You have two options, place `cargo-outdated` into a directory that is already located in your `$PATH` variable (To see which directories those are, open a terminal and type `echo "${PATH//:/\n}"`, the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 `$PATH` or you have root permission (or via `sudo`), simply copy the `cargo-outdated` to that directory `# sudo cp cargo-outdated /usr/local/bin`
**Option 2**
If you do not have root, `sudo`, or write permission to any directory already in `$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-outdated` 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-outdated ~/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-outdated\binary"
```
Otherwise, ensure you have the `cargo-outdated` 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-outdated` ensure `cargo-outdated.exe` is inside that directory as well).
### Options
There are a few options for using `cargo-outdated` which should be somewhat self explanatory.
```
USAGE:
cargo outdated [FLAGS] [OPTIONS]
FLAGS:
-a, --aggressive Ignores channels for latest updates
-h, --help Prints help information
-q, --quiet Suppresses warnings
-R, --root-deps-only Only check root dependencies (Equivalent to --depth=1)
-V, --version Prints version information
-v, --verbose Use verbose output
-w, --workspace Checks updates for all workspace members
rather than only the root package
OPTIONS:
--color <color> Coloring: auto, always, never [default: auto]
[values: auto, always, never]
-d, --depth <NUM> How deep in the dependency chain to search
(Defaults to all dependencies when omitted)
--exit-code <NUM> The exit code to return on new versions found [default: 0]
--features <FEATURE> Space-separated list of features
-m, --manifest-path <PATH> An absolute path to the Cargo.toml file to use
(Defaults to Cargo.toml in project root)
