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. Initial inspiration taken from seancorfield/dot-clojure.

For use with Clojure CLI tools version 1.10.1.697 or above

Check the version of Clojure CLI tools currently installed

clojure -Sdescribe

Installing Clojure deps.edn

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.

Updating Practicalli clojure-deps-edn

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The versions of libraries are manually updated at least once per month using the :outdated alias and a new version of the deps.edn file pushed to this repository.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clojure -M:project/outdated

Common development tasks

How to run common tasks for Clojure development

Task	Command	Built-in
Create project (clojure exec)	`clojure -X:project/new :template app :name practicalli/my-app`	Add alias
Create project (clojure main)	`clojure -M:project/new app practicalli/my-app`	Add alias
Download dependencies	`clojure -Spath` or `clojure -P` (plus optional aliases)	Yes
Run the project	`clojure -M -m domain.main-namespace`	Yes
Run the project	`clojure -X:project/run -m domain.main-namespace`	Add alias
Find libraries (mvn & git)	`clojure -M:project/find-deps library-name`	Add alias
Check for new dependency versions	`clojure -M:project/outdated`	Add alias
Run tests	`clojure -M:test/runner`	Add alias
Package library	`clojure -X:project/jars`	Add alias
Deploy library locally	`clojure -X:deps mvn-install`	Yes
Package application	`clojure -X:project/uberjar`	Add alias

Most aliases use the -M flag. Only use the -X flag when you know it is supported by that task

Aliases

Aliases provide additional configuration when running a REPL, an application or to use a community tool.

add or remove dependencies
add or remove directories on the class path
define a function or main namespace to run, along with arguments

Clojure CLI main flag options

Flag	Purpose	Config used
`-M`	Run Clojure project with clojure.main	deps, path, `:main-opts` & command line args
`-P`	Prepare / dry run (CI servers, Containers)	deps, path
`-P -M:aliases`	Prepare / dry run including alias deps and paths	deps, path
`-P -X:aliases`	Prepare / dry run including alias deps and paths	deps, path
`-X`	Execute a qualified function, optional default arguments	deps, path, `:exec-fn`, `:exec-args` & :key val args
`-J`	Java Virtual Machine specific options (menory size, etc)

deps = :deps, :extra-deps, replace-deps
path = :path, :extra-paths, replace-paths

REPL experience

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

repl/rebel - run a Clojure REPL
repl/rebel-cljs - run the default ClojureScript REPL
repl/rebel-nrepl - run rebel REPL with nrepl connection for editor connections (eg. CIDER, Calva)
:env/dev include dev/ in classpath to configure REPL startup actions using dev/user.clj

Command	Description
`clojure -M:repl/rebel`	Run a Clojure REPL using Rebel Readline
`clojure -M:alias:repl/rebel`	Run a Clojure REPL using Rebel Readline, including deps and path from alias
`clojure -M:env/dev:repl/rebel`	Run a Clojure REPL using Rebel Readline, including deps and path from `:env/dev` alias to configure REPL start
`clojure -M:repl/rebel-cljs`	Run a ClojureScript REPL using Rebel Readline
`clojure -M:alias:repl/rebel-cljs`	Run a ClojureScript REPL using Rebel Readline, including deps and path from alias

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

Clojure Projects

Create projects from deps, leiningen and boot templates with clj-new
Check and update project dependencies
Package projects as jar and uberjars
Deploy projects locally and to Clojars

Create new projects from templates

:project/new - create a new project from a template

Create a new project (via clojure.main - classic approach)

clojure -M:project/new luminus practicalli/full-stack-app +http-kit +h2 +reagent +auth

Create a new project (Edn command line arguments - recommended approach)

Command	Description
`clojure -X:project/new`	library project called playground
`clojure -X:project/new :name practicalli/my-library`	library project with given name
`clojure -X:project/new :template app :name practicalli/my-application`	App project with given name
`clojure -X:project/new :template luminus :name practicalli/full-stack-app +http-kit +h2`	Luminus project with given name and template options

Running projects

Run project with or without an alias:

clojure -M:alias -m domain.app-name
clojure -M -m domain.app-name

The -M flag is required even if an alias is not included in the running of the application. A warning will be displayed if the -M option is missing.

In the project deps.edn file it could be useful to define an alias to run the project, specifying the main namespace, the function to run and optionally any default arguments that are passed to that function.

:project/run
{:ns-default domain.main-namespace
 :exec-fn -main
 :exec-args {:port 8888}}

Then the project can be run using clojure -X:project/run and arguments can optionally be included in this command line, to complement or replace any default aruments in exec-args.

Project dependencies

:project/check - detailed report of compilation errors for a project
:project/outdated - report newer versions for maven and git dependencies
:project/outdated-mvn - check for newer dependencies (maven only)

Command	Description
`clojure -M:project/check`	detailed report of compilation errors for a project
`clojure -M:project/find-deps library-name`	fuzzy search Maven & Clojars
`clojure -M:project/find-deps -F:merge library-name`	fuzzy search Maven & Clojars and save to project deps.edn
`clojure -M:project/outdated`	report newer versions for maven and git dependencies
`clojure -M:project/outdated-mvn`	check for newer dependencies (maven only)

Project packaging

Build a project archive file for deployment

:project/jar - build jar for deps.edn project
:project/uberjar - build uberjars for deps.edn project
:project/uberdeps - uberjar builder

Command	Description
`clojure -X:project/jar :main-class domain.app-name`	package `project.jar` for deps.edn project (publish library)
`clojure -X:project/uberjar :main-class domain.app-name`	package `uber.jar` for deps.edn project (deploy application)

Additionally specify :jar name and if ahead of time compilation should be used (default true)

clojure -X:project/jar :jar '"practicalli.app.jar"' :aot false :main-class domain.app-name

Project Deployment

Deploy a project archive file locally or to Clojars.org

-X:deps mvn-install - built-in Clojure CLI alias to deploy a Jar locally in the ~/.m2/repository directory
:deploy/clojars - deploy jar to clojars.org
:deploy/clojars-signed - sign and deploy jar to clojars.org

Command	Description
`clojure -X:deps mvn-install project.jar`	[NEW] deploy jar file to local maven repository, i.e. `~/.m2/repository`
`clojure -M:project/clojars project.jar`	deploy jar file to Clojars
`clojure -M:project/clojars-signed project.jar`	deploy signed jar file to Clojars

Set Clojars username/token in CLOJARS_USERNAME and CLOJARS_PASSWORD environment variables.

Set fully qualified artifact-name and version in project pom.xml file

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

clojure -X:deps mvn-install project.jar for local deployment of jars is part of the 1.10.1.697 release of the Clojure CLI tools in September 2020.

Java Sources

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 (e.g. "/usr/lib/jvm/openjdk-11/lib/src.zip")

:lib/java8-source
:lib/java11-source

Use the aliases with either -M or -X flags on the Clojure command line.

Databases and drivers

Databases and drivers, typically for development time inclusion such as embedded databases

:database/h2 - H2 embedded database library and next.jdbc

clojure -M:database/h2 - run a REPL with an embedded H2 database and next.jdbc libraries

https://cljdoc.org/d/seancorfield/next.jdbc/CURRENT/doc/getting-started#create--populate-a-database

Use the aliases with either -M or -X flags on the Clojure command line.

Data Inspectors

(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.

Reveal is a repl and data visualization tool

Reveal - read evaluate visualize loop. A REPL with data visualisation. Also used as a tap> source

inspector/reveal - repl and data visualization tool
inspector/reveal-nrepl - repl and data visualization tool with nrepl server, for connection from Clojure aware editors

`clojure -M:inspect/reveal-light:repl/rebel`	Start a Rebel REPL with Reveal dependency & light theme. Add reveal as tap> source

Running different types of repl

Using Clojure exec -X flag, the default repl function can be over-ridden on the command line, supplying the io-prepl or remote-prepl functions.

clojure -X:inspect/reveal io-prepl :title '"I am a prepl repl"
clojure -X:inspect/reveal remote-prepl :title '"I am a remote prepl repl"'

Configure theme & font

Add a custom theme and font via the -J command line option or create an alias using :insepct/reveal-light as an example.

clojure -M:inspect/reveal -J-Dvlaaad.reveal.prefs='{:theme :light :font-family "Ubuntu Mono" :font-size 32}'

Rebel Readline & Reveal: Add Reveal as tap> source

Evaluate (add-tap ((requiring-resolve 'vlaaad.reveal/ui))) when using Rebel Readline to add Reveal as a tap source, showing (tap> ,,,) expressions in the reveal window, eg. (tap> (map inc [1 2 3 4 5])).

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

Cognitect REBL

Visualize the results of each evaluation in the REPL in the REBL UI. Navigate through complex data structures.

Cognitect REBL aliases requires several separate install steps before they are operational

inspect/rebl - REBL, a visual data explorer (Java 11)
inspect/rebl-java8 - REBL, a visual data explorer (Oracle Java 8)

Command	Description
`clojure -M:inspect/rebl`	Start REBL REPL and UI (Java 11)
`clojure -M:inspect/rebl-java8`	REBL REPL and UI (Java 8)
`clojure -M:lib/cider-nrepl:inspect/rebl:middleware/nrebl`	REBL REPL and UI with nREPL server (CIDER, Calva)

Middleware

Aliases for libraries that combine community tools and REPL protocols (nREPL, SocketREPL).

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.

nREPL

:middleware/nrepl - Clojure REPL with an nREPL server
:middleware/cider-clj - Clojure REPL with nREPL server and CIDER dependencies for cider-connect-clj
:middleware/cider-cljs - ClojureScript REPL with nREPL server and CIDER dependencies for cider-connect-cljs

Use the aliases with either -M or -X flags on the Clojure command line.

Command	Description
`clojure -M::middleware/nrepl`	Run a Clojure REPL that includes nREPL server
`clojure -M::middleware/cider-clj`	Run a Clojure REPL that includes nREPL server and CIDER connection dependencies
`clojure -M::middleware/cider-cljs`	Run a ClojureScript REPL that includes nREPL server and CIDER connection dependencies

Cognitect REBL with CIDER

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

:middleware/nrebl - REBL data browser on nREPL connection
:lib/cider-nrepl - include nrepl, cider-nrepl and refactor-nrepl library dependencies (support :inspect/nrebl alias)

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

clojure -M:lib/cider-nrepl:inspect/rebl:middleware/nrebl

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

To start a REBL REPL from cider-jack-in-clj add a .dir-locals.el file to the root of a Clojure project. The .dir-locals.el configuration adds the nREBL aliases set via cider-clojure-cli-global-options and all other automatically injected configuration is disabled (to prevent those dependencies over-riding the nREBL aliases).

((clojure-mode . ((cider-preferred-build-tool . clojure-cli)
                  (cider-clojure-cli-global-options . "-M:lib/cider-nrepl:inspect/rebl:middleware/nrebl")
                  (cider-jack-in-dependencies . nil)
                  (cider-jack-in-nrepl-middlewares . nil)
                  (cider-jack-in-lein-plugins . nil)
                  (cider-clojure-cli-parameters . ""))))

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:

clojure -M:graph/deps navigate # navigable folder of SVGs
clojure -M:graph/deps single # deps-graph.dot file
clojure -M:graph/deps single -o deps-graph.png -f png
clojure -M:graph/deps single -o deps-graph.svg -f svg
clojure -M:graph/deps single --show # View graph without saving

Performance testing

Performance testing tools for the REPL

:performance/benchmark

Use the aliases with either -M or -X flags on the Clojure command line.

TODO: check these alias combinations are correct

clojure -M:performance/benchmark:repl/rebel

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

TODO: check these alias combinations are correct Performance test a project in the REPL

clojure -M:performance/benchmark:repl/rebel

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

:performance/memory-meter - memory usage

Use the aliases with either -M or -X flags on the Clojure command line.

In the REPL:

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

Experimental / Alpha Aliases

:alpha/carve - EXPERIMENTAL, use with caution - carve out unwanted vars in code
:alpha/hot-load - EXPERIMENTAL, use with caution - hot-load libraries into a running namespace.

Hot loading dependencies (unofficial - changes planned already)

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.

:project/hotload-dep - 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)

Library repositories

Repositories that host libraries for Clojure.

central and clojars are the man repositories for Clojure development are consulted in order.

central and clojars repos can be removed from consideration by setting their configuration hash-map to nil in ~/.clojure/deps.edn. For example, {:mvn/repos {"central" nil}}.

The order of additional repositories 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

Americas mirrors

 :mvn/repos
 {"google-maven-central" {:url "https://maven-central.storage-download.googleapis.com/maven2/"}}

Europe mirrors Use only one mirror entry for a specific repository, to ensure a repeatable build.

 :mvn/repos
 {"google-maven-central" {:url "https://maven-central-eu.storage-download.googleapis.com/maven2/"}

 ;; UK specific mirror
 "uk"      {:url "http://uk.maven.org/maven2/"}

  ;; CDN access to clojars
