<hightower2> But they did have some ruby-specific workarounds, to solve the problem of ruby not supporting method overloading. For example, on the first call of a Qt function, ruby args would be classified to find the most similar overload in C++, and then that method would be cached, so that the next invocation would directly use the cached version instead of doing the argument type comparison again
<Papierkorb> Yeah, Crystal can do method overloading though
<hightower2> But apart from trivia knowledge, not particularly useful/needed in the case of crystal
<hightower2> yeah
<Papierkorb> used Qt4 and later Qt5 with C++ a lot before using Ruby. Did my fair share of hacks with it too. God bless that mess. QObject::setUserData() was the best thing ever lul.
<oprypin> in python you can set arbitrary members on qt objects :p
<_tsound> i want to perform a loop that gets the files in a folder and reads the filename back to me
<adam12> _tsound: what have you tried?
<adam12> _tsound: If you want to get files in a folder, you likely want one of the mehods in Dir, like
entries
<adam12> here's the docs for Dir of course. https://crystal-lang.org/api/0.23.1/Dir.html
<adam12> I have to sign off. Late here. Night.
<_tsound> thanks for the help adam12
<_tsound> i think this will work
<_tsound> what i get is "/home/user/work/pname/pname"
<_tsound> Process.executable_path.to_s.chomp("/pname")
<_tsound> It's dirty, but it'll work for now
@bararchy Do you have crystal syntax issues?
So
def (bar: String) looks good
but
def (bar: Array(Int32)) looks bad
def (bar: String) looks good
but
def (bar: Array(Int32)) looks bad
the issue is always the first ')' in the def
I think it just thinks that it's the end of the parentesis
a parser issue
I'll update my sublime package
<RX14> thanks!
