[racket-users] keystroke logger for DrRacket editor?

I’m interested in analyzing my own programming patterns in DrRacket. Has anyone already written a keystroke logger / editor-change-logger for DrRacket? I’m imagining that it would capture a session record starting with a known snapshot, then a sequence of keystrokes/edit actions, in such a way

Re: [racket-users] incantation for library module to access a data file in the same directory?

You probably want to use `define-runtime-path`, like this: ``` (require racket/runtime-path) (define-runtime-path rtd "realtime-test-data.rkt") (define (fun-timed-test-2) (define ip (open-input-file rtd)) ... rest of function ...) ``` Sam On Tue, May 12, 2015 at 11:42 AM thomas.lynch < thoma

[racket-users] accessing a directory local file to a module

I apologize if this posted before, but given a day I don't see it here.. I have a function with a companion data file (data file is part of the collection). When I invoke it with a relative path name (just the file name), racket looks for it in the directory the function is invoked from, not th

Hi Stephen Thanks for the encouragement, and the tips: I was wondering especially about item 3. Once I get my head around what's needed to connect up a custom reader, I should be in a position to have a shot ... and ask further questions. Dan -- You received this message because you are subscri

[racket-users] Use Parsack to parse a #language?

I've been having a great time playing with Stephen Chang's Parsack (parsec-style parsing for Racket) and enjoying the straightforward learning curve and usability. Thanks Stephen! Has anyone used Parsack to do the parsing for a little language and th

[racket-users] incantation for library module to access a data file in the same directory?

I created a collection, then used raco to install it. Ran into a problem where a test function within module X in the collection accesses a file in the same directory as the source code: (define (fun-timed-test-2) (define ip (open-input-file "realtime-test-data.rkt")) (match-define (li

Is there a way to show examples in scribble docs that uses code? If there’s not, would something like this be good: @code-examples[#:lang “at-exp racket”]|{ (+ 1 2) @+[1 2] }| Renders as: Examples: > (+ 1 2) 3 > @+[1 2] 3 ? On May 12, 2015, at 7:10 AM, Alexis King wrote: > Continuing my

Continuing my attempts to make a working meta-language, I'm now working on improving the documentation. I'd like to be able to use “interaction” from scribble/eval with a custom evaluator, but I'm having trouble getting a custom evaluator to work with my language. I've tried using (make-module-
