Python's if __name__=="__main__": main() in other languages

This behavior is very hard to Google. For now, I'm calling it "scripted main" and I'm cataloging it for several programming languages.

Ruby: if __FILE__ == $0 then main end

Perl: unless(caller) { main; }

...

Does anyone know the syntax for this in GNU Smalltalk?



PHP: if (realpath($argv[0]) == __FILE__) main();

(Presuming you've gone and defined the main() function somewhere. No module conventions like with Python here.)


for node.js

if (!module.parent) { // your main here }


Thanks! That one's at https://github.com/mcandre/scriptedmain/blob/master/scripted... and https://github.com/mcandre/scriptedmain/blob/master/test.js
