pcrecpp syntax is unclear

[myonlake]

Hey,

The pcrecpp library MTA uses for regular expressions is unknown to me. The syntax is for whatever reason different from what PHP and JavaScript uses, even though as far as I know PHP uses the exact same library?

Can someone lend me a hand figuring out the right syntax for this, as it seems this gives zero results when using pregFind/match.

^[^local ]function (.*?)\( 

Flags: mi

Everywhere else:

/^[^local ]function (.*?)\(/gmi 

local function testing1( ) 
  
end 
  
function testing2( ) -- matches on regex101, but not via MTA's pregs 
  
end 
  
addEventHandler( "test", 
    function( ) 
        
    end 
) 

To those who don't know what this is, don't bother replying.

MTA devs didn't know anything on irc today, so hoping someone knows here...

Your pcre syntax does not match anything in php or javascript either.

Test it here and you will see: https://regex101.com/#pcre

Remove the first anchor and it will work:

[^local ]function (.*?)\( 

(Im completely newbie at using regular expressions so don't ask me more about it)

Sorry, wrong code in the first post, updated now with proper formatting.

The first anchor is there for a reason, anyway (compare step count as well).
