Report issues and suggest features and improvements on the GitHub issue tracker. Don’t ask questions on the issue tracker - use the support channels instead.

If you want to file a bug, please provide all the necessary info listed in our issue reporting template (it’s loaded automatically when you create a new GitHub issue).


Patches in any form are always welcome! GitHub pull requests are even better! :-)

Before submitting a patch or a pull request make sure all tests are passing and that your patch is in line with the contribution guidelines.


Good documentation is just as important as good code.

Consider improving and extending this manual.

Working on the Manual

The manual is generated from the asciidoc files in the doc folder of nREPL’s GitHub repo and is published to Antora is used to convert the manual into HTML. The filesystem layout is described at

To make changes to the manual you simply have to change the files under doc. The manual will be regenerated manually periodically.

You can build the documentation locally from the repo.

$ cd
$ npm install
$ ./antora site.yml
If npm install fails, see Antora’s troubleshooting documentation.

If you want to make changes to the manual’s page structure you’ll have to edit nav.adoc.


While nREPL is free software and will always be, the project would benefit immensely from some funding. Raising a monthly budget of a couple of thousand dollars would make it possible to pay people to work on certain complex features, fund other development related stuff (e.g. hardware, conference trips) and so on. Raising a monthly budget of over $5000 would open the possibility of someone working full-time on the project which would speed up the pace of development significantly.

We welcome both individual and corporate sponsors! We also offer a wide array of funding channels to account for your preferences (although currently Open Collective is our preferred funding platform).

If you’re working in a company that’s making significant use of nREPL we’d appreciate it if you suggest to your company to become a nREPL sponsor.

You can support the development of nREPL, CIDER, clojure-mode and inf-clojure via Open Collective, Patreon, Liberapay and PayPal.
