[clojure] add cljstyle format tool

[practicalli-johnny]

Provide a format tool for the Clojure language linters

Proposal

Add cljstyle to the Clojure language linters with a default configuration that matches the Clojure Style Guide (which it does by default)

cljstyle provides a binary to check and fix Clojure code (.clj, .cljs, .cljc, .edn) and can format code following the Clojure style guide.

cljstyle can be configured via the .cljstyle file, so can easily be configured by the end user as well as provide a default configuration

• for example: https://github.com/practicalli/dotfiles/blob/main/.cljstyle

cljstyle is available as part of the setup-clojure GitHub Action, so having the same tool in MegaLinter would help with consistency and allowing easy migration path to MegaLinter if desired.

Alternatives

cljfmt is a library cljstyle was based on. cljfmt is not availabe as a binary, so would either require building or uses as a library.

zprint is available as a binary, although it is a more general file formatting tool that requires more understanding to configure. zprint may be a useful addition along with cljstyle, especially if a good default configuration can be defined.

Nice proposition :)

Can it take a list of files as arguments ?

Would you eventually like to make a PR ? :)

Nice proposition :)

Thank you

Can it take a list of files as arguments ?

Yes, a specific file or set of files can be passed to cljstyle - e.g https://github.com/greglook/cljstyle#check-and-fix

Would you eventually like to make a PR ? :)

I would be happy to take a look, although it will have to be in a few weeks as I have a pressing deadline for my current employer (and still have some covid symptoms - hence the slow reply)

@practicalli-john I know what it is... I understand, especially the part with being overloaded by tasks at our non-open-source jobs :)
I wish you to get better, good luck :)

I let this issue open, we'll see who will make the PR first ^^ ( it can also be another contributor ^^ )

[practicalli-johnny]

I've started a pull request to add cljstyle, not sure if it is correct as yet.

I have only added the megalinter/descriptors/clojure.megalinter-descriptor.yml to which I made a manual change. It was not clear if I should include all the assets that build.sh generated afterward, or if the GitHub workflows generated these files.

I replied in the PR comments :)
