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-aliases
tag for the last version of this repository before these changes
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.

- Experimental
For use with Clojure CLI tools version 1.10.1.697 or above
Check the version of Clojure CLI tools currently installed
clojure -Sdescribe
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The versions of libraries are manually updated at least once per month using the :outdated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clojure -M:project/outdated
How 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)

- see this video for an example https://youtu.be/u5VoFpsntXc?t=2166
Most aliases use the
-M
flag. Only use the-X
flag when you know it is supported by that task
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

Rebel readline provides a feature rich REPL experience, far beyond the basic clojure
and clj
commands.
repl/rebel
- run a Clojure REPLrepl/rebel-cljs
- run the default ClojureScript REPLrepl/rebel-nrepl
- run rebel REPL with nrepl connection for editor connections (eg. CIDER, Calva):env/dev
includedev/
in classpath to configure REPL startup actions usingdev/user.clj
Command | Description |
---|---|
clojure -M:repl/rebel |

clojure -M:alias:repl/rebel |
Run a Clojure REPL using Rebel Readline, including deps and path from alias |

clojure -M:repl/rebel-cljs |

- Check and update project dependencies
- Package projects as jar and uberjars
- Deploy projects locally and to Clojars
: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 |

clojure -X:project/new :name practicalli/my-library |
library project with given name |
clojure -X:project/new :template app :name practicalli/my-application |

clojure -X:project/new :template luminus :name practicalli/full-stack-app +http-kit +h2 |
Luminus project with given name and template options |
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
.

commands, providing the require cider middleware libraries that are auto-injected in ccider-jack-in-
commands.

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).

Performance testing tools for the REPL
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))
: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

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/
