Re: [racket-users] Getting a sandboxed evaluator to work with a custom #lang's reader
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
?

Greg Hendershott can probably fill you in on more unpleasantries, as his markdown parser is the biggest client (that I currently know of) So, my experience with parsing languages -- and parsing generally -- is very thin. All I know is that I found Parsack delightful to use for parsing markdown. The fact that Parsack can handle something as weird as markdown, doesn't necessarily mean that it's inappropriate for something like a sane language grammar. Instead I think that, with a sane grammar, you have additional plausible choices like parser-tools and ragg, and they might parse faster (?). -- You received this message because you are subscribed to the Google Groups Racket Users group.

[racket-users] Re: Use Parsack to parse a #language?
Once I get my head around what's needed to connect up a custom reader Matthew's example from his talk at the first RacketCon (and other conferences) might be a good place to start: https://github.com/mflatt/scratchy/blob/master/scratchy/reader.rkt https://github.com/mflatt/scratchy/blob/master/scratchy/parser.rkt I seem to recall that Racket used to come with a combinator parser library. It's been removed but I don't remember why (Replying to myself) I found the old library. Looks like it was discontinued for lack of a maintainer. http://planet.racket-lang.org/package-source/plt/combinator-parser.plt/1/0/planet-docs/combinator-parser/index.html -- You received this message because you are subscribed to the Google Groups Racket Users group.

[racket-users] Use Parsack to parse a #language?
I've been having a great time playing with Stephen Chang's Parsack http://stchang.github.io/parsack/parsack.html (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 then plugged it into the main Racket infrastructure? Good idea? Mismatched tool? What does it / would it take?

[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 (list completed result) (fun-timed 2 (λ(e#) (read-line ip (close-input-port ip) (and completed (string=? result #|)) ) Now when this is run: pkgs/liquid-lib/liquid/realtime (fun-timed-test-2) ; open-input-file: cannot open input file ; path: /home/deep/liquid-lib/examples/keyword-ap/realtime-test-data.rkt ; system error: No such file or directory; errno=2 ; [,bt for context] The test data file is there in the same directory with the module (in ../realtime/), but racket is looking for the file in the directory the function is being invoked from (../examples/keyword-ap/). I've gone through the documentation, and the collects path doesn't help, because this was a directory install, so the catalog is pointing to the original source directory. There is a function (get-module-path) but I'm not sure that is doing what I want, or at least I don't know the correct incantation to make it go at it isn't giving me the path back from (get-module-path X).

Hi Stephen Thanks for the encouragement, and the tips: I was wondering especially about item 3.

[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 the directory the module is in. This was ok during development, but now that the module is installed it is a problem. The collects path does not help, as directory install does not move the collection. I think maybe (get-module-path) but I haven't been able to get it work. Any tips appreciated! -- You received this message because you are subscribed to the Google Groups Racket Users group.

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 thomas.ly...@reasoningtechnology.com wrote: I created a collection, then used raco to install it.
