is there a way of doing "callbacks" ( i.e. passing function as argument to be called later ) ?

This is a question Chris did to me and it reminded me some related questions i forgot to ask: Is there a type "function" or type "Class" ? Is there anyway for "evaluating" a string to chuck code in order to do dynamic calls ( like javascript "eval" function for instance ) ?

Class yes, function no unfortunately. The workaround I use is small "functor" classes, similar in style to inner classes in java. E.g. https://github.com/heuermh/lick/blob/c3ad1e94a226001b4c6229fb0c741cef046f743... https://github.com/heuermh/lick/blob/c3ad1e94a226001b4c6229fb0c741cef046f743... Some doc here (that needs a lot of updating) https://github.com/heuermh/lick/wiki

You might be able to hack this by writing to a temp file and Machine.add'ing it. michael

Fucking good answer in no-time ! I fucking love this list ! Actually i would love to know more about chuck source code so i could somehow help to improve. I swear chuck is in my priority list, was love at first sight. lets keep this list hot ( : On 22 May 2012 23:19, Michael Heuer wrote:

You might be able to hack this by writing to a temp file and Machine.add'ing it.

Indeed. These are valid things to desire, Lisp and its decendants are alive, fun and well still (or finally, one might argue)... but I feel compelled to point out that this is the direction where old maps would write "here be dragons" and modern games would have you encounter 3 health items and a save-point.

Man, long time i didn't get that excited with programming stuff ( this year i'll make 15 years of programming ) - like programming shit instead of sleeping, the day my boss/coworkers start to find my late posts in the chuck list i'll be probably fired! HAHA Hopefully i'll be able to do some push requests to the project in this year ( i have some unfinished projects in the priority + dayjob ). Completely changing the direction of the conversation, i know some instituions sometimes give sponsor$hip for a period of development in open source software, did anybody from chuck team tried that ? happy chucking On 23 May 2012 00:14, Kassen wrote:

This is really great to hear.

Well, Princeton and Stanford more or less sponsor ChucK by employing (most of?) the developers and of course by providing ChucK with web-space. I could imagine more of that. In the past I have speculated that there might be a institute willing to sponsor some development on making ChucK and the MiniAudicle more accessible to blind users. We have some people on board who are visually challenged and when I look at mainstream music programs I can quite easily see how they would end up with ChucK or a similar system. That said; there are reportedly still some less than ideal bits for those users. That's just one area where I could imagine that there might be some funding and where somebody might pick it up and help improve the world a bit. There are likely many more. Nice to read a mail as enthusiastic as yours. Rock on! Kas.

That is sooo deliciously nasty, and I don't see why it couldn't work. I wish I'd thought of it.

It will work surely. Hopefully someone will have some energy soon to put this hack inside a native function in chuck. Can't wait to try stuff on the sources. respect, peace On 23 May 2012 16:51, Robert Poor wrote:

Hi All, Henrique, I highly encourage you to take a deep look at Michael Heuer's LiCK library. There are some great things in there that take advantage of a functional paradigm in a generally functional-unfriendly language. And while we're talking about functional style and other nerdery, I submit for your consideration my attempt to implement a Closure in Chuck to avoid overmuch global state. This should appeal to you JavaScript geeks out there as well. It's influenced by ideas in LiCK. And while it's a bit harder to read than your traditional Chuckian style, it's the most bang-for-buck (in terms of lines of code) I could get out of Chuck in a short session. Comments most welcome.

I'll need a bit of time to figure out and do some tests on this tricks. I still very kiddo on chuck, for instance i don't know what "<<" does. Anyway i liked the Constructor workaround, and as soon as i get back to chuck will see also how possible is to mess the source as well. thanks for the energy on this subject cya On 24 May 2012 18:39, mike clemow wrote:
