20:51 <alex-guenther> hi

20:52 <asterite> hi alex

20:52 <asterite> thanks for those wiki updates :)

20:52 <alex-guenther> you're welcome

20:53 <alex-guenther> what is the status of the c callbacks? are they kind of useable ... for playing around_

20:56 <asterite> They have some issues… and if they form a closure they blow up (it's not yet implemented)

20:56 <asterite> so you have to be careful not to use outside variables… but you can use a "self" pointer

20:56 <asterite> What are you trying to do?

20:57 <alex-guenther> well a while ago I was lookin if it is possible to write a sqlite3 wrapper...

20:58 <asterite> Oh, that would be nice

20:59 <asterite> You can use a class a a hidden "self" parameter for the callback

21:00 <asterite> Hmmm...

21:00 <alex-guenther> I think I would like to try to write some code examples to see how crystal behaves ... may be usefull for others. Well right now I've got a job with PHP (after working with rails) I miss writing beautiful code, and crystal feels like the language that is really fun

21:01 <asterite> You can take a look at the Thread class: https://github.com/manastech/crystal/blob/master/src/thread.cr

21:01 <asterite> In the initialize method theres: PThread.create(out @th, nil, ->start(Void*), nil)

21:02 <asterite> so that passes a callback to the "start" method of the Thread class

21:02 <asterite> You can do something like that for now until we implement function pointers, function literals and closures well

21:02 <asterite> Ah, I forgot to say: it's nice to hear that (that crystal feels like the language that is really fun)

21:16 <alex-guenther> thanks, I'll try to get something working... bye
