Dep First Search

Me: mom, can we have $CRATE?
Mom: we have $CRATE at home.

depfirstsearch lets you search your Rust project's current dependency tree for crates. Don't cargo add new crates for features you already have.

Consider this scenario:

You start a project, add dependencies once in a while, and after a year or two you have a sprawling tree of hundreds of transitive dependencies. When you reach for a new crate, stop, and check transitive dependencies you already have at home. You might already be compiling that which you need.

Installation

cargo install depfirstsearch

Usage

From any directory inside your crate or cargo workspace:

depfirstsearch REGEX

Example:

Q: I need a glob crate and plan to install wax, but wait, do I already have a glob crate?

$ depfirstsearch glob
glob@0.3.1
	Support for matching file paths against Unix shell style patterns.

How it works

depfirstsearch loops through every crate in the cargo metadata output, collects stringified name/version/description/keywords, then applies your search term/regex to each, and print the ones that match.
