Question

Given the text

public void MyFunction(int i, String str, boolean doIt) {
    Log.i(TAG, "Enter MyFunction(int i, String str, boolean doIt)");

I want to make some replacements on the second line, but not the first

public void MyFunction(int i, String str, boolean doIt) {
    Log.i(TAG, "Enter MyFunction( i:" + i + ", str:" + str ", doIt:" + doIt + ")");

So far using the following regex I manage to get these results:

find “\w+\s+(\w+)([,\)])“
replace with “$1:" + $1 + "$2“

public void MyFunction(i:" + i + ", str:" + str ", doIt:" + doIt + ") ") {
    Log.i(TAG, "Enter MyFunction( i:" + i + ", str:" + str ", doIt:" + doIt + ") ");

Is there any way to force the replace to be executed only on the Log.i lines?

EDIT:
I tried the following regex
“Log\.i\(.*?\((\s*(\w+\s+(\w+)([,\)]))+“
but $1,$2,$3 only contains the last match (the last argument: doIt)

$1=boolean doIt)
$2=doIt
$3=)

when there should be 3 sets of $1,$2,$3, one for each argument.
If you know how to retrieve multiple matches, that would also make for a solution

Answer 1

I caved,

I used this little perl to do the job:

next unless /Log\.i/;
s/TAG,/TAGG/;
s/(final\s+)?[^ \(]+\s+(\w+)([,\)])/$2:\" \+ $2 \+ \"$3/g;
s/TAGG/TAG,/;

with the command line:

perl -pi <scriptname> <file>

If someone still wants to contribute some, I understand I could have run perl as Eclipse external tool to process the java files. How do I do that?

UPDATE:

I wrote a post on how to use external perl to run the script from within Eclipse IDE
