Linux:

A cargo subcommand for displaying when Rust dependencies are out of date

cargo-outdated is for displaying when dependencies have newer versions available.

The functionality of cargo-outdated largely depends on the cargo builtin command cargo update.

To retrieve the list of available SemVer compatible dependencies, cargo-outdated firstly creates a temporary workspace, then executes cargo update against it, finally compares the temporary dependency tree with the original one.

Similarly, to check the latest dependencies, cargo-outdated replaces the SemVer requirements of direct dependencies with wildcards then goes through the same process.

Once installed (see below) running cargo outdated in a project directory looks like the following:

$ cargo outdated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"))

The latest version of cargo-outdated can be installed or updated with cargo install:

cargo install --locked cargo-outdated

or

cargo install --locked --git https://github.com/kbknapp/cargo-outdated

Follow these instructions to compile cargo-outdated, then skip down to Installation.

1. Ensure you have current version of cargo and Rust 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 Clone the project $ git clone https://github.com/kbknapp/cargo-outdated && cd cargo-outdated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 Once complete, the binary will be located at target/release/cargo-outdated

All you need to do is place cargo-outdated somewhere in your $PATH. Then run cargo outdated anywhere in your project directory.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.

You have two options, place cargo-outdated into a directory that is already located in your $PATH variable (To see which directories those are, open a terminal and type echo "${PATH//:/\n}", the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)

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cp cargo-outdated ~/bin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

This library depends on OpenSSL. On MacOS a newer version of OpenSSL than is installed by default is needed. This can be installed with Homebrew via brew install openssl or openssl can be vendored in with --features vendored-openssl. Learn more about building OpenSSL here,

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

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).

There are a few options for using cargo-outdated which should be somewhat self explanatory.

The MSRV of this crate is what is required to run cargo outdated, you may be able to compile cargo outdated itself on an earlier version of Rust. However, because cargo oudated uses cargo internally, it requires a specific minimum version to run successfully.

The current MSRV can be found in the Cargo.toml under the package.rust-version field.
