Regular Expression for Find and Replace?

Something like this?

"function\W*([^\(\W])\(\)\{\n"

"function $1(){\ndebugObject.traceFunction("$1");\n"

 

Don't do that. Look up in the compiler manuals what macros exist that evaluate to the function name. Like __func__ .

 

Regex find and replace is implemented differently for each text editor/IDE but basically it's:


function <- the word function
\W* <- one or more whitespace characters
([^\(\W]) <- match anything not ( nor whitespace, e.g. function name
\(\) <- brackets ()
\{\n <- open curly brackets + linebreak

The replace works the same way but $1 will contain the match.

 

Based on Hansr's explanation, I would guess that the specification of whitespace characters is different for your regex processor.

Two other common ways of specifying a whitespace character are:
\S or \s
[:space:]

The latter is supposedly the POSIX standard, but sometimes you need extra square brackets on both sides because the regex processor treats square bracket characters specially too.
