i have a bunch of calls in a repo of code like this:
$out = $this->call('myApp.Settings.Menus.something.doSomething', $input);
I'd like to find all instances of it using regex where the first param of $this->call() contains only 1 period.
i'm getting closer, i think, with this: (?=\$this->call\(')(\.){1}(?=',)
Why isn't it limited to 1 period?
What you're looking for is a simple:
'[^.]+?[.][^.]+?'
Which means any number of non-dots, folled by a dot, and some non-dots again.
Better yet, be a bit more precise:
'\w+?([.]\w+?)?'
This matches alphanumeric characters, and a dot. Second half (optional)?.
(Your (\.){1} would just match a single period.)
The following should work, namespace will be in the first capture group:
\$this->call\('([^'.]*\.[^'.]*)',
If you want to use a lookbehind/lookahead so that the namespace is the only part of the string matched by the regex, you can use the following:
(?<=\$this->call\(')[^'.]*\.[^'.]*(?=',)
This is a safe regex:
\$this\s*\-\>\s*call\s*\(\s*[\'\"]\.[\'\"]
It accounts for whitespaces between language characters like:
$this -> call ( '.'
where it is still technically correct syntax. Additionally this is indifferent to single or double quoted string as teh first parameter.
