02:14 <polypus74> jemc: just use this as base frolvlad/alpine-glibc and it runs!!!

18:56 <avsej> hi guys, is there printf() equivalent for pony? I cannot find it in stdlib

21:54 <doublec> avsej: No really. There's 'print' plus string concatenation.

21:55 <doublec> avsej: so, env.out.print("Hello " + " world" + somevar.string())

21:58 <SeanTAllen> although that concatenation is relatively slow because of extra allocations. see https://patterns.ponylang.org/performance/limiting-string-allocations.html

22:31 <avsej> doublec, does it also mean that I have to carry env everywhere I need to output something?

22:44 <SeanTAllen> no, you need to carry env.out

22:44 <SeanTAllen> you dont want to pass `env` around. that gives a lot more access than you want, in particular env.root

22:45 <SeanTAllen> you would pass env.out (which is a tag reference to the out actor) to anything that needs write to standard out

22:45 <SeanTAllen> if you dont provide access to env.out then you can be assured that other parts of your program wont access it.

22:46 <SeanTAllen> they could however bypass that by using C FFI to call @printf, however you can limit FFI access to certain parts of your program to prevent that

22:47 <SeanTAllen> hopefully i didnt overload you with too much info. the short version is: supply env.out to anything that needs to print to standard out.

23:06 <avsej> thank you

23:09 <SeanTAllen> you're welcome

23:14 <mvzink> how can i associate a docstring with a field? i get a syntax error if i try to do a """-docstring right before a field, but after the class's docstring.
