[racket-users] test suite for hygienic expander?

Is there a test suite for the macro expander? I assume that you must have one, but it would save me some effort if somebody can tell me where it is. I'm interested in finding out if you have good corner cases for testing a proposal for a hygienic expander. --Mitch -- You received this messag

[racket-users] Racket function to get data from a Google Sheet?

Has anybody written a Racket function to extract the data directly from a Google Sheet? I know I can export the Google sheet as a csv, and then use read-csv-file, but I'd like to automate the export step. --Mitch -- You received this message because you are subscribed to the Google Groups "Rac

[racket-users] Mann-Whitney test?

Does anybody have an implementation of the Mann-Whitney U test (or the equivalent Wilcoxson Rank test) in Racket? I imagine I could easily hack up my own, but somebody else may have done a better job of it already. --Mitch -- You received this message because you are subscribed to the Google Gr

[racket-users] testing for timeout in Rackunit?

Of course you can't test for non-termination, but is there a relatively simple way to write something like (check-doesnt-terminate-quickly ) which would fail if the thunk terminates within the time limit, and succeeds otherwise? This would be useful in testing expressions that are claimed n

[racket] "upload file" button in a Racket web server

Many web pages have an "upload file" button that allows the user to drag&drop a file onto the button, and then hitting the button sends the file to the server. Is there any way of doing this in a Racket web server? If not, how close can we come? --Mitch Racket Users list:

[racket] shift/release shift keys in universe module

Does releasing a shift key cause a key event in 2htdp/universe ? I want to distinguish between ordinary mouse click and shift click. What I'd like is to have a sequence like keyevent: "shift" (or "rshift") mouse-event: button-down [or whatever] keyevent: ???(I release the shift key) I sup

[racket] multi-line strings in ISL?

Is there a good way to create multi-line strings in ISL? For example, instead of producing output in the form (list "(* 11 " " 22 " " 33 " " 44 " " 55) ") [where here I've padded the strings out to 80 characters to force the Racket printer to produce e

[racket] etags support for DrRacket

It took me about 45 minutes, but I found the following bit of trivia helpful: To convince etags to look for definitions in .rkt files do the following: Create a file ~/.ctags , and add to it the following line: --langmap=scheme:.rkt This will cause ctags/etags to recognize .rkt files as schem

[racket] reading an image from a file?

Silly question: How can I read a file and treat its contents as an image? eg, I'd like to say something like: (define cat-image (read-image "cat-image.png")) The immediate advantage of doing this, rather than Insert|Image is that I can keep my .rkt file in text form, so I can use other tools on i
