Regular expression for following requirement.

Question

0.00/5 (No votes)

See more:

I am using following regular expression for matching function.

FINDFUNC_RE = re.search('^\s*(?:(?:inline|static)\s+){0,2}(?!else|typedef|return)\w+\s+\*?\s*(\w+)\s*\([^0]+\s*?', Line)

It correctly matches if line is like this:

static int abc(int a)

But it does not matches if the line is like this(Contain * after return type):

static int* abc(int a)

How to match both string correctly?

What I have tried:

<pre>FINDFUNC_RE = re.search('^\s*(?:(?:inline|static)\s*+){0,2}(?!else|typedef|return)\w+\s+\*?\s*(\w+)\s*\([^0]+\s*?', Line)

I have added * in regex but it does not work.

As per RegEx definition, * is a special char in a RegEx, to match it one must escape it as \*
I got it, from original RegEx, the space must be optional:

^\s*(?:(?:inline|static)\s+){0,2}(?!else|typedef|return)\w+\s+\*?\s*(\w+)\s*\([^0]+\s*?
                                                           ^^^
                                                           \s*

Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx:
Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx:
