Re: [racket-users] [handin-client] `raco pkg install $URL` vs `raco setup -A $localPath`: getting lost with Racket packages

The package system knows the currently installed checksum. There's not currently a simple function to look up the checksum for a given package name, but you could use (require pkg/lib) (define (get-pkg-checksum pkg-name) (define info (for/or ([scope (in-list (get-all-pkg-scopes))])

Re: [racket-users] Overriding sexp highlighting in drracket

The highlighting you're interested in changing is the (by default) grey highlighting that moves around when you change the insertion point (when you use the arrow keys, say), right? If so, I think the code you're looking for is the match-parens private method in framework/private/color. You can

[racket-users] Racket in a web page (via Whalesong)

Hi, Does anyone use Whalesong to script web pages? As far as I understand the Racket design, Whalesong is enough to bootstrap full Racket in a JS environment. It's a great opportunity. I would like very much to have an interactive lisp development where I can develop both server side and

Re: [racket-users] [handin-client] `raco pkg install $URL` vs `raco setup -A $localPath`: getting lost with Racket packages

An easier way is: * Create a Git repo (e.g., at GitHub) for your handin client. It's a good idea to name the repo something specific to your class, as opposed to just "handin". For example, the one for my class is https://github.com/mflatt/uu-cs5510.git * Optionally, register

Re: [racket-users] [handin-client] `raco pkg install $URL` vs `raco setup -A $localPath`: getting lost with Racket packages

Thanks a lot! It sounds... amazingly simpler. It even supports branches! Even readding support for auto-update sounds easy, to prevent human errors by students. (It's certainly less work than I spent working around the current system). I might even integrate this in the docs. The "hard part" is

Re: [racket-users] Overriding sexp highlighting in drracket

Let's say I have the following: (let ([x (foo bar)] ... ) In the regular drracket editor, when I move the cursor between the ) and ] it highlights (foo bar). In the vim emulator, the cursor has been replaced by a block that highlights a character, rather than a line just before it. So the same

[racket-users] [handin-client] `raco pkg install $URL` vs `raco setup -A $localPath`: getting lost with Racket packages

Hi all, my research group is going to teach using How to Design Programs (2nd ed.), and I'm currently automating deployment of the handin-client with auto-update. Since the handin-client (and the auto-updater) was written for the old "package management system" (Planet), I'm having some trouble

A few days ago, I made a pull request (#1030) against plt/racket. Jay McCarthy approved it… but now I don’t see it on master. I’m guessing… that these commits need to be made to git.racket-lang.org instead, and then they get force-pushed to the github account. Is this correct? If so, I’ll just
