practicalli/clojure-deps-edn provides a user wide configuration, ~/.clojure/deps.edn, for over 30 aliases to support Clojure CLI and tools.deps project development. These aliases use meaningful and descriptive names to avoid clashes with project specific aliases, ensuring that the user wide aliases remain available in all projects.

Aliases with common options are provided for convenience and to minimize the amount of cognitive load required to remember how to use aliases. Inspiration taken from seancorfield/dot-clojure.

Fork the practicalli/clojure-deps-edn repository and clone your fork to an existing ~/.clojure/ directory (eg. $HOME/.clojure or %HOME%.clojure).

git clone your-fork-url ~/.clojure/

The configuration from ~/.clojure/deps.edn is now available for all Clojure CLI projects for that user account.

Any directory containing a deps.edn file is considered a Clojure project. A deps.edn file can contain an empty hash-map, {} or hash-map with configuration. The project deps.edn file is merged with the user wide configuration, with the project deps.edn keys taking precedence if there is duplication.

See the rest of this readme for examples of how to use each alias this configuration contains.

The collection of aliases is regularly reviewed and expanded upon and suggestions are most welcome.

The versions of libraries are manually updated at least once per month using the :outdated alias and a new version of the deps.edn file pushed to this repository.

cd ~/.clojure/
clojure -A:outdated

Here is a summary of the aliases included so far.

Please read the deps.edn file to see the specific configuration for each alias.

Create and update projects from deps, leiningen and boot templates with clj-new

• :new

Create a new project: clojure -A:new template-name domain/namespace

Run project: clojure -m myname.myapp

Rebel readline provides a feature rich REPL experience, far beyond the basic clojure and clj commands.

• rebel - run a Clojure REPL
• rebel-cljs - run the default ClojureScript REPL, eg. Nashorn
• rebel-nrepl - run rebel REPL with nrepl connection for editor connections (eg. CIDER, Calva)

:repl/help in the REPL for help and available commands. :repl/quit to close the REPL.

• :dev include dev/ in classpath to configure REPL startup actions using dev/user.clj

Reveal is a repl and data visualization tool

• repl-reveal - repl and data visualization tool
• clojure -A:repl-reveal-themed - repl and data visualization tool with light theme
• repl-reveal-nrepl - repl and data visualization tool with nrepl server, for connection from Clojure aware editors

clj -A:repl-reveal to start a Reveal repl with data visualization window that shows all values.

;; clojure -R:repel-reveal -A: rebel clojure -R:repl-reveal -A:rebel to start a REPL with Rebel Readline with Reveal dependency. Evaluate (add-tap ((requiring-resolve 'vlaaad.reveal/ui))) to add Reveal as a tap source, showing tap> expressions in the reveal window.

clojure -R:repl-reveal -A:rebel -J-Dvlaaad.reveal.prefs='{:theme :light :font-family "Ubuntu Mono" :font-size 32}' to run Rebel Readline with Reveal using a light theme. Change the values in the map for a different theme.

Practicalli Clojure - data browsers section has more details on using reveal.

Portal (new project) Navigate data in the form of edn, json and transit Practicalli Clojure -data browsers section - portal

• inspector-portal-cli - Clojure CLI (simplest approach)
• inspector-portal-web - Web ClojureScript REPL
• inspector-portal-node - node ClojureScript REPL

(require '[portal.api :as portal]) once the REPL starts. For inspector-portal-web use (require '[portal.web :as portal]) instead

(portal/open) to open the web based inspector window in a browser.

(portal/tap) to add portal as a tap target (add-tap)

(tap> {:accounts [{:name "jen" :email "[email protected]"} {:name "sara" :email "[email protected]"}]}) to send data to the portal inspector window (or any other data you wish to send)

(portal/clear) to clear all values from the portal inspector window.

(portal/close) to close the inspector window.

Browse data structures as they are generated in the Clojure REPL.

• cognitect-rebl - REBL, a visual data explorer (Java 11)
• cognitect-rebl-java8 - REBL, a visual data explorer (Java 8)

Run the REBL REPL with nREPL server so CIDER can connect.

• :nrebl - REBL data browser on nREPL connection
• :nrepl - include nrepl library dependency (supports :nrebl alias)
• :cider-nrepl - includes cider-nrepl and refactor-nrepl library dependencies (supports :nrebl alias)

In a terminal, run REBL listening to nREPL using the command

clojure -R:nrepl:cider-nrepl:cognitect-rebl -A:nrebl

cider-connect-clj in Spacemacs / Emacs and CIDER successfully connects to the nREPL port and evaluated code is sent to REBL.

To use cider-jack-in-clj, create a .dir-locals.el file in the root of the project with the following aliases:

((clojure-mode . ((cider-clojure-cli-global-options . "-R:nrepl:cider-nrepl:cognitect-rebl -A:nrebl"))))

Run a REPL on the command line for access by cider-connect- commands, providing the require cider middleware libraries that are auto-injected in ccider-jack-in- commands.

• :cider-clj
• :cider-cljs

Include Java source on the classpath to look up Java Class and method definitions, eg. cider-find-var in Emacs Requires: Java sources installed locally, examples from Ubuntu package install locations

• :java-8-source
• :java-11-source

Unit test libraries, specifications and generative testing

clojure-test requires no alias as it is a part of the Clojure jar file. If not using a test running the :test-path alias may be required to add the test directory to the class path in order to see test code.

• :spec - define specifications for functions and data structures

• :spec2 - under active development

• :expectations - clojure.test with expectations

• :expectations-classic - expectations framework

Use expectations in a project clojure -A:test:expectations or from the command line with cognitect test runner clojure -A:expectations:test-runner-cognitect

Tools to run unit tests in a project which are defined under test path.

Run clojure with the specific test runner alias: clojure -A:test-runner-alias

• :test-runner-cognitect - Cognitect test-runner
• :test-runner-cljs - test runner for Clojure/Script
• :test-runner-kaocha - comprehensive test runner for Clojure/Script
• :test-runner-midje - runner for midje and clojure.test tests
• :test-runner-eftest - fast and pretty test runner

Cloverage - simple clojure coverage tool for clojure.test defined unit tests.

Run clojure with the test coverage alias: clojure -A:test-coverage

• :test-coverage

• :lint - comprehensive and fast lint tool

• :lint-eastwood - classic lint tool for Clojure

• :idiom-check - checking for idiomatic Clojure code with Kibit

• :carve - EXPERIMENTAL, use with caution - carve out unwanted vars in code

Manage versions for maven and git dependencies

• :outdated - report newer dependencies (git and maven)
• :outdated-update - update all dependencies (git and maven)
• :outdated-ancient - check for newer dependencies (maven)

This is a very unofficial approach to hot loading and the design may change quite soon, so this alias is likely to break without notice. Do not rely on this alias working and use with caution.

• :hot-load-deps - Add jar dependencies into a running REPL.

Require the add-lib function to include a maven style dependency

(require '[clojure.tools.deps.alpha.repl :refer [add-lib]])
  (add-lib 'domain/library {:mvn/version "RELEASE"})

Require clojure.tools.gitlibs namesapace to hot load dependencies from a Git repository

(require '[clojure.tools.gitlibs :as gitlibs])
(defn load-master [library]
  (let [git (str "https://github.com/" library ".git")]
    (add-lib library {:git/url git :sha (gitlibs/resolve git "master")})))
(load-master 'clojure/tools.trace)

Create Graphviz graphs of project and library dependencies

Morpheus creates grahps of project vars and their relationships

• :graph-vars - generate graph of vars in a project as a .dot file
• :graph-vars-png - generate graph of vars in a project as a .png file using src and test paths
• :graph-vars-svg - generate graph of vars in a project as a .svg file using src and test paths

Install Graphviz to generate PNG and SVG images. Or use the Edotor website to convert .dot files to PNG or SVG images and select different graph layout engines.

Vizns creates graphs of relationships between library dependencies and project namespaces

• :graph-deps
• :graph-deps-png - generate a single deps-graph png image

Other options:

• clj -A:graph-deps navigate # navigable folder of SVGs
• clj -A:graph-deps single # deps-graph.dot file
• clj -A:graph-deps single -o deps-graph.png -f png
• clj -A:graph-deps single -o deps-graph.svg -f svg
• clj -A:graph-deps single --show # View graph without saving

Build a project archive file for deployment

• :build-depstar - build jars, uberjars for deps.edn projects

clojure -A:depstar -m hf.depstar.jar MyLib.jar
clojure -A:depstar -m hf.depstar.uberjar MyProject.jar

• :build-uberdeps - uberjar builder

Deploy a project archive file locally or to Clojars.org

• :deploy-locally - copy jar to ~/.m2/ directory
• :deploy-clojars - deploy jar to clojars.org
• :deploy-clojars-signed - sign and deploy jar to clojars.org

Deploy Locally: clojure -A:deploy-locally project.jar Deploy to Clojars: clojure -A:deploy-clojars project.jar Deploy to Clojars signed: clojure -A:deploy-clojars-signed project.jar

Path to project.jar can also be set in alias to simplify the Clojure command.

Set Clojars username/token in CLOJARS_USERNAME and CLOJARS_PASSWORD environment variables. Set fully qualified artifact-name and version in project pom.xml file

• :benchmark Adhoc performance testing the the REPL

clojure -A:rebel:bench

(require '[criterium.core :refer [bench quick-bench]])
(bench (adhoc-expression))

Performance test a project in the REPL

clojure -A:rebel:bench

(require '[practicalli/namespace-name]) ; require project code
(in-ns 'practicalli/namespace-name)
(quick-bench (project-function args))

• :measure - memory usage In the REPL:

  (require '[clj-memory-meter.core :as memory-meter])
   (memory-meter/measure (your-expression))

Repositories that host libraries for Clojure.

If using a mirror for a repository the original repository should not be included as well. The order in which repositories are consulted is not guaranteed, so may cause unpredictable side effects in the project build especially if RELEASE or LATEST tags are used rather than a numeric library version.

Maven supports explicit mirror definition in ~/.m2/settings.xml and Clojure CLI tools(tools.deps) supports this configuration. Adding Maven Central or a mirror to ~/.m2/settings.xml negates the need for its entry in deps.edn configuration.

Recommended repositories

• central - Maven Central, the canonical repository for JVM libraries, including Clojure releases
• clojars - clojars.org, the canonical repositories for Clojure community libraries fronted by a contend delivery network service, https://repo.clojars.org/

Optional repositories

• sonatype - snapshots of Clojure development releases, useful for testing against before new stable releases.
• jcenter - the largest mirror of all open source libraries (useful as a backup or accessing through corporate firewalls)
• `business-area** - example of adding a local Artifactory server for your team or business area.
• google-maven-central - Maven Central mirror hosted on Google Cloud Storage - Americas, Asia, Europe
