Re^4: linting for undefined object methods

This all makes sense to me, but given the constraint of statically defined methods, would it be reasonable to have the linter locate method names in known namespaces or else give warning? For method invocations on references where the class cannot be known at compile time, this would at least catch the 'method doesn't exist anywhere in a known namespace' type of error. I understand that this is not useful in the general case, but with 100K lines of code strewn over 200 files and classes with fairly verbose method names it sure would be nice to know that

$dataView->htmTable('edit');
[download]

will fail when the method is actually called

sub htmlTable { }
[download]

When $dataView's class cannot be known, having 'htmlTable' exist somewhere in the application namespace is clearly no guarantee of success at runtime... but missing the 'htmTable' bug is a *definite* guarantee that there will be a problem. A lint check, imperfect as it may be, still seems to offer value in my case.

This all makes sense to me, but given the constraint of statically defined methods, would it be reasonable to have the linter locate method names in known namespaces or else give warning? So if any namespaces contains a sub, all classes are considered to define that sub? You could do that. It should help against typos.	[reply]

The linter would warn if the method name could not be located in any namespace, ie. `[Thu Sep 3 10:38:06 2009] ajaxGetDRCFilesTable.cgi: subroutine call $ +drc->searchDirectory() does not refer to any defined sub. line 223` [download] This would catch the deadly typo that gets missed during test. If I get a free moment, I'll take a look at some of the approaches proposed here to do something for our situation. Thanks for the help.	[reply] [d/l]

Wouldn't testing coverage be simpler and find more problems.	[reply]
