Re: [Jgeneral] [Jprogramming] Report on the J wiki meeting of May 26, 2022

[Paul Jackson]

Thanks for the vote of confidence, but I was really thinking only of the
J-Playground. I don't use the call dll capabilities, but I do think it
would be wise to think about the ability of one to break out of the
sandbox. I know nothing about the one the J-Playground is using, but it is
worth considering.

Re: [Jgeneral] J Language Server process

[Joe Bogner]

I also think it would be a worthwhile project as I spend a fair amount of
time in vscode and emacs

Re: [Jgeneral] J Language Server process

[Raul Miller]

I am not aware of anyone having implemented this.

But, it sounds like a fun project. I'd be interested in seeing where
you take it. (Or, now that you mention it, I might be inclined to
implement it myself if you get stalled. Ring me up if parts of it look
to be too daunting.)

Thanks,

Re: [Jgeneral] [Jprogramming] wiki maintenance

[chris burke]

The code2 site is a test wiki used by bob and his team for trying out new
pages.  It is not part of the maintenance.

We know of some missing pages and are trying to fix that now.

[Jgeneral] J Language Server process

[Nicholas Peterson]

I'm newer to j programming and would love to use more common tooling (vs code, 
sublime, eMacs, etc). It seems those applications typically have a community 
contributed j syntax highlighting package and not much else. After looking a 
bit, it seems a language server protocol is the typical way these applications 
expect to get language feedback. Has anyone attempted one for J?

I wonder if this would be a good start for myself becoming active in the J 
community?
