Re^3: Catching typos

My IDE highlights the word in yellow (warning), and hovering over it produces the following pop-up: Unable to find sub definition, declaration, constant definition or typeglob aliasing. It also throws a yellow dot at the line where the warning is located, so even if that line isn't in view on the screen, I can always see if there are any warnings/errors anywhere within the file at a glance. Everything happens live-time, so I can actually see it immediately after I'm done typing.

Here's an image of what I'm speaking of. If I point at the word, the notice pops up.

Interesting. .. my guess is it's running Perl::Critic in the background. So what happens if you have an AUTOLOAD defined? NB: You'd need parens for `reeturn()` then. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]

It's the Perl5 Camelcade plugin for intelliJ IDEA. I've been using it religiously (along with the Vim plugin, of course) for numerous years now. I'm doubtful that it uses Perl::Critic, as it works just fine if that distribution isn't installed. I'm quite sure it uses its own parser, but I am not 100% sure either way. It works the exact same way with Python, JS/jQuery etc. The only Perl distributions that I install in support of this software is Devel::Camelcadedb, which simply supplies Perl debug support within the IDE.

The docs of Camelcade talk about sub resolution, but I'm not sure how it's implemented. Inspecting the Op-Tree could be a way, cause B::Deparse shows that it's a method call and B::Xref lists all subs. Camelcade also warns that sub resolution is not 100% reliable. Unless an implementation offers it via "Language Server Protocol" I doubt one can call it a common IDE feature. And I'd really like to know how the existence of a sub AUTOLOAD is handled...
