[racket-users] documentation discovery and navigability (Was: Python's append vs Racket's append and helping novices understand the implications)

Recent Python experience that might inform Racket docs... I'm recently dusting off my Python skills[1], while switching to Python 3, so I'm checking documentation for every little thing. It was a little surprising to me, that the current official Language and Standard Library references did

[racket-users] modules as a data format

Hi Racketeers, I've got what seems like a common way to use a #lang, make the #%module-begin provide a certain name and use a local-require to get the contents. I'm using Jens Axel's urlang and including the compiled JavaScript in some Xexpressions later on. Here's how I've set up my

1. I think this is a great start for a generic introduction to data structures. Someone should integrate Jens’s short table: https://stackoverflow.com/questions/27584416/in-racket-what-is-the-advantage-of-lists-over-vectors/27589146#27589146

Re: [racket-users] Quickscript error on first startup of Racket 7.2

I've pushed a repair. It should be integrated with the next racket nightly release I suppose. The fix is to check the compiled version of all scripts in the library, and if it differs from the current racket version it gets recompiled. The bonus is that scripts that have not been compiled yet

[racket-users] Re: "raco test" causes my reader to fail on carriage return (but newline works)

Progress! Either rebooting, upgrading to 7.2, or something else caused DrRacket to start failing in the same way that raco does*. Now it feels like a normal problem I can solve using my normal techniques (of scattering printlns everywhere). (* I was wrong when I said that "raco setup" was

I think having such migration pages for people coming from other languages is a good idea. Maybe also should include basic programming knowledge such as "a single linked list is not a vector", but then where to begin? If such page says that some operations are slower on Racket lists (append), then
