:editor format refactor

Yea, I’m really not thrilled with the current state of code formatting in Julia. I’m hoping @kiranshila will get some more time to work on julafmt in the future, but for now GitHub - domluna/JuliaFormatter.jl: An opinionated code formatter for Julia. Plot twist - the opinion is your own. seems to be the standard, and it would probably be worth supporting that.

That looks like it’s a library though, how would I use that to format a buffer? Is a wrapper script needed or something?

#43

Yea, you’d probably want a wrapper script. https://codeberg.org/FelipeLema/julia-formatter.el seems relevant here.

#44

That starts up a local web service, way more complex than this needs to be and definitely out of scope of apheleia

#45

You can thank Julia’s JIT-AOT compiling + (current) lack of binary caching :crai:

Kiran’s juliafmt would be in rust and hence fine, but it’s still in alpha ATM.

This one looks like a no-for-now then.

Are you able to offer any input on ESS? If you use it :stuck_out_tongue: AFAICT all I need is an R formatter for that one, have a couple but I’m not sure how much that misses out

#47

I haven’t really got any comments on that.

Would it be possible to make format-all-mode an alias for apheleia-mode? This would make possible for people to seamlessly transition.

#49

Also, for Go, the formatter also needs to be updated (it uses a Lisp expression).

#50

I don’t understand what you want from this. The package will be replaced with no interaction needed.

#51

Using a list is fine

#52

People may have stuff like (add-hook 'python-mode-hook #'format-all-mode) (as hinted in the documentation). This won’t work anymore as they have to use to apheleia-mode. But maybe this is not worth the trouble.

#53

This is:

  (set-formatter! 'gofmt
    '(("%s" (if (or +format-region-p
                    (not (executable-find "goimports")))
                "gofmt"
              "goimports"))))

This is not handled by the current code (despite the comment of set-formatter! saying otherwise) and apheleia does not know how to handle it either and tries to execute it as is.

I suppose it could be:

  (set-formatter! 'gofmt
    (if (or +format-region-p
                    (not (executable-find "goimports")))
                "gofmt"
              "goimports"))
#54

Can’t imagine why, and yeah it probably is

#55

OK well it’ll be removed anyway since it doesn’t do anything vs upstream

#56

I’ve always used styler for R

#57

Yeah I found styler for R, but my understanding is the ESS module is used for other languages too.

Is just provider styler good enough?

I’ve set up the following script for R formatting (in format_stdin.sh which is in PATH):

#!/usr/bin/env sh

unset R_HOME
/usr/local/bin/Rscript -e "library(styler); txt <- readLines(file('stdin')); write(style_text(txt), stdout())"

And added the following to config.el

(set-formatter! 'styler '("format_stdin.sh") :modes '(ess-r-mode))
