I stumbled upon an excellent blog post "<https://www.cs.yale.edu/homes/lucas.paul/posts/2017–07–31-making-an-editor.html|Making an Editor>" (à la DrRacket) from Lucas Paul. Considering the "<https://gankra.github.io/blah/text-hates-you/|Text Rendering Hates You>" and "<https://lord.io/text-editing-hates-you-too/|Text Editing Hates You Too>" (plus the HN-news discussions https://news.ycombinator.com/item?id=21105625\|here and https://news.ycombinator.com/item?id=21384158\|here.) I’d be interested, if somebody can share some insights in regard to DrRacket. (Thanks in advance)

you can post in #drracket and Robby would be the one with most of the answers

Ah. I didn’t know about the #drracket - thx.

Hi. I need to use the websocket streaming data api RFC 6455 WebSockets for Racket . I was wondering if anyone knows whether this package can handle streaming data that have been compressed.

@mflatt after I run raco setup --mode errortrace -l typed-racket, I don’t see a subdirectory named errortrace under package directories of typed-racket . Is this a bug or am I missing anything?

I’ve installed packages of typed-racket via linked directories ➤ raco pkg show -l typed-racket-lib Installation-wide: Package Checksum Source typed-racket-lib #f (link "/Users/capfredf/code/racket-extra-pkgs/typed-racket/typed-racket-lib")

It looks like --mode was never implemented for parallel builds. So, it works for -j 1, but not by default (on a machine with multiple cores).

By “works”, I mean it creates some new directories. I’m not convinced that it does the right thing for modules that are already loaded by the time raco setup starts compiling in the new mode.

Yes: raco setup builds on raco make, and raco make follows dependencies. I can imagine that’s not what you want in this case, though.

actually if the builds were done in parallel, it would be fine for me.
