I'd say that's relatively rare. I've seen it used in implimenting interpreters.

Hi! Quick question on command line parsing with command-line. I'm using #:ps flag clause to put a message at end of usage display, but seems it won't take anything but literal string -- (format "Something ~a" value) is right out. Any way to get around this? I like command-line, but want to have version display automatically!
<technomancy>
oofoe: hey, nice to see you on the game jam. my kids liked your entry.
<technomancy>
we gotta get more racket entries next time!
<oofoe>
Very glad you liked it!
<oofoe>
Hoping to release a "director's cut" very soon with a nicer tileset and some of the howler bugs fixed at least!
<oofoe>
I have been very happy using Racket for these -- except for the small problem with sound... ; - )
<technomancy>
did you end up using big bang or one of the newer libs?
<oofoe>
For sound?
<oofoe>
I didn't actually do anything -- I wrote the bulk of the game in the four hours before submission so I really didn't have time to experiment... ; - )

technomancy, Can you point me to the sound libs you're referring to? I'm not familiar with them.
<technomancy>
oofoe: oh, I don't mean for sound, just overall
<oofoe>
Oh sorry, was hoping you had the secret to sound success on Racket! What is "big bang" then?
<technomancy>
big-bang is a built-in racket library that you can use for simple games
<technomancy>
it features prominently in the book How to Design Programs
<oofoe>
Oh, no... I wrote everything from scratch (except for some bits and bobs I reused from "Slime Leak"), just using the existing GUI library.

<oofoe>
The 377 lines in %harmony.rkt is the whole thing. Only specific dependencies are racket/gui and racket/runtime-path (in the latest version).
<technomancy>
ah gotcha. well maybe next time you should take a look at big-bang; it lets you write the games in a purely-functional way.
<oofoe>
I will take a look! Thanks for the recommend!

can anybody give me any tips or pointers on how to development of racket/gui works? I'd like to take a stab at fixing this: https://github.com/racket/gui/issues/144 but I don't know how to build and test changes I make in the racket/gui repo

Hi! Can someone tell me how to enforce constraints between syntax/parse terms, please? I would like to make a template that enforces that some term is syntactically equal to another within the same template.
<raoul1>
In which 'equality-constraint-fail' would enforce syntactical equality between both 'a' s. Right now it's complaining because of the duplicate pattern, which is to be expected. But how can I express that, please? Thanks!
<raoul1>
Is using something such as '#:when (equal? ...)' after my template the way to go?
