Notepad++ has a Function List feature that allows for quick jumping to functions. This is all fine and dandy, but I find that if I'm working in JavaScript and use anonymous functions, then it quickly becomes very silly; my current file has almost 100 instances of "function" in the list!

I know that it has a filter, but that only allows you to search for a specific function. Is there a way I can filter out anonymous functions (or any function names in general)?

You can modify the regular expression that finds the functions (see Notepad++ help).

Find the js_function parser and change the first nameExpr inside the functionName element from

"[_A-Za-z][\w_]*[\s]*[=:]|[_A-Za-z]?[\w_]*[\s]*\("

to

"[_A-Za-z][\w_]*[\s]*[=:]|(?<=function )[_A-Za-z]?[\w_]*[\s]*\("

This adds a lookbehind to the expression, ensuring that the word "function " (including a space) precedes the function name. If it doesn't, it's an anonymous function and will not show up in the function list.

    Excellent! David Blanchard's answer worked like a charm. BTW - the file that David is referring to is functionList.XML and is found in: C:\Users\<USER NAME>\AppData\Roaming\notepad++

  • Now, the suggested trick does not work anymore because npp does not support look behind operations (see the Notes on regular expressions for parsers in npp-user-manual.org/docs/function-list/…)
