practicalli/clojure-deps-edn provides a user level configuration, containing 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.
The Practicalli Clojure book uses this configuration extensively to help you develop Clojure projects and learn the Clojure language.
MAJOR CHANGES: practicalli/clojure-deps-edn recommends using Clojure CLI tools version 1.10.1.697 or later. Aliases are now qualified keywords, which is recommended in general for using keywords in Clojure. Use the
classic-aliasestag for the last version of this repository before these changes

For use with Clojure CLI tools version 1.10.1.697 or above
Check the version of Clojure CLI tools currently installed
clojure -SdescribeClojure CLI tools creates a configuration directory called .clojure, which by default is placed in the root of the operating system user account directory, e.g. $HOME/.clojure.
XDG_CONFIG_HOME may be set by your operating system and over-rides the default location, e.g. $HOME/.config/.clojure
CLJ_CONFIG can be used to over-ride all other location settings
Check the location of your Clojure configuration directory by running
clojure -Sdescribeand checking the:config-uservalue.
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, usually :paths and :dependencies and perhaps some :aliases.
The project deps.edn file is merged with the user wide configuration, e.g $HOME/.clojure/deps.edn, with the project deps.edn keys taking precedence if there is duplication, otherwise they are merged.
Configuration passed via the command line when running clojure or the clj wrapper will take precedence over the project and user level configuration if there is duplication, otherwise they are merged.
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. The antq project is used to report new library versions, sent to an org file which is then used to update the changelog.
cd ~/.clojure/
clojure -M:project/outdated > outdated.orgHow to run common tasks for Clojure development.
- Built-in tasks require no additional configuration.
- User aliases should be added to
~/.clojure/deps.edn. - Project aliases should be added to the individual project deps.edn file (or may be part of a template).
- User/Project alias can be defined in both user and project deps.edn files (typically added to project deps.edn for external running such as Continuous Integration)

Run project with or without an alias:
clojure -M:alias -m domain.app-name
clojure -M -m domain.app-nameThe
-Mflag is required even if an alias is not included in the running of the application. A warning will be displayed if the-Moption 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.

Connecting nREPL based editors
Use the :inspect/reveal-nrepl alias when running the REPL, either in the terminal or via an nREPL based editor (CIDER, Calva, Conjure, Cursive, etc.)
Alternatively, add an .nrepl.edn file to the root of a project to include the Reveal middleware
{:middleware [vlaaad.reveal.nrepl/middleware]}
Cider jack-in and reveal
See the Reveal section of Practicalli Clojure for full details, including how to set up a .dir-locals.el configuration.

:inspect/reveal-nrepl-cider is a light version of the above.
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.

:alpha/carve- EXPERIMENTAL, use with caution - carve out unwanted vars in code:alpha/hotload-libs- EXPERIMENTAL, use with caution - hot-load libraries into a running namespace.
Hot loading dependencies (unofficial)
This is an unofficial approach using to hot loading and the API may change in future
:alpha/hotload-libs- Add jar dependencies into a running REPL.
Practically Clojure details how to hot-load libraries into a running REP using tools.deps.alpha.
The Clojure Webapp hotload libraries repository contains and example project that uses add-libs to hotload library dependencies.
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 releasesclojars- 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
