/prog/ - Shorthand if()?

Name: Anonymous 2008-05-06 4:39

sup /prog/,

I was wondering whether any of you would use in lieu of

if(cond)

 do_something();

the equivalent

cond && do_something();

or something like this for a function that returns 0 on error:

(s=get_foo()) || fprintf(stderr,"Error getting foo\n");

of course, multiline if-statements would be a bad idea with this, but how about if statements with a single body statement?

well i think gcc supports terniary ? thing with no else clause.

It doesn't work if do_something returns void, and it feels kinda silly to change to a different construct based on the return type of the then-clause.

What... why? Don't they like `if'?

(when cond (do_something))

Fuck "if" if there's no "else" clause.

Maybe it disables them because they're incompatible, so the developers of the extensions should port them.

Are you guys still using the legacy Firefox 2? I have used Firefox 3 for the last two years.

You're still using Firefox 3? Get the mozilla-central Fx4 builds.

Yeah, I'm actually using the 04-04 Firefox beta ;__;

I should get myself a PKGBUILD that instead downloads the latest nightly tarball like I used to do, but first I'll have to make sure everything is put in /usr and not /opt.
