Depo

A simple CLI tool to easily managage dependencies for Clojure projects. Supports deps.edn, Leiningen, Shadow-cljs and Babashka project configurations. It uses rewrite-clj and zprint under the hood to rewrite your configuration files.

Why

The simplest way to add a dependency to a Clojure project is to first find the artifact coordinates. Then, depending on whether you use Leiningen or you need the Maven artifact coordinates, you look for that and add it to your configuration. There are a few tools to help ease this flow.

For one, there is clj -X:deps find-versions, which downloads a bunch of jars on first start up and returns a bunch of versions. Some other tools include depot (the similar naming is coincidental), ancient-clj and neil, which also has other features, like adding common aliases.

While all of these tools have their own merits, they have their own drawbacks too, such as being slow to start up (all JVM based CLIs, including Depo for now), or only supporting edn configuration files, or not having a CLI at all.

Depo aims to cover these bases.

NOTE

Depo is still a work in progress. See the roadmap

Usage

Depo CLI

To try Depo out, you can use this one liner:

clojure -Sdeps '{:deps {org.clojars.some/depo {:mvn/version "RELEASE"}}}' -M -m depo.core --help

Alternatively, you can add the following to your aliases:

{:depo {:extra-deps {org.clojars.some/depo {:mvn/version "RELEASE"}}
        :main-opts [ "-m" "depo.core"]}

Now you can run clojure -M:depo --help.

Depo Library

You can also use Depo as a library.

Example

(ns example
  (:require [depo.resolver :as r]))

(r/get-release-version "reagent") ;=> "1.2.0"
(r/conform-version "org.clojure/clojure") ;=> {:groupID "org.clojure", :artifactID "clojure", :version "1.5.0-alpha3"}
(r/version-exists? "org.clojure/clojure" "0.20.7") ;=> false

For more information, see the API documentation.

Installation

Depo can be built and installed as a native image:

1. Install GraalVM
2. Clone this repo
3. Run clj -T:build native-image or, if you have babashka installed, bb native-image
4. The binary is now in target/. Copy it to somewhere on your path.

Features / Commands

To see a list of commands, run depo --help.

Depo first looks for a config file in your current working directory in the following order:

1. deps.edn
2. project.clj
3. shadow-cljs.edn
4. bb.edn

It then uses first config file that it finds for its operations.

Global Flags

There are flags that you can set if you'd like to override the default behavior of the commands.

• --file/-f - Use a different config file instead of the default file Depo finds.

Add

Usage

# simple usage
depo add org.clojure/clojure

# If the groupID and artifactID are the same, you can ommit the groupID
depo add reagent

# Use specific version
depo add reagent@1.11.0

# Use a different config file instead of default
depo -f bb.edn add metosin/malli

Remove

Usage

depo remove clj-http

Update

Usage

# Updates a specific dependency
depo update metosin/malli

# Updates all dependencies
depo update
