Skip processing current pattern and continue with next

[David Klein]

I want to stop processing the action of the current pattern and continue with the next pattern.
I am familiar with "continue", "break" and "next" but none seem to do what I want.

For example:

pattern1 {

many lines, nested loops etc.​

if (condition) Skip_rest_of_pattern1_and_continue_with_pattern2​

many lines, nested loops etc.​

}

pattern2 {

more code​

}

When you are on pattern1 and if condition occurs you simply do nothing and skip to the next pttern2.

For example you have a file:
david_klein.txt

line 1 bar
line 2
line 3 foo bar baz
line 4
line 5

and this script:
david_klein.awk

# awk -f david_klein.awk david_klein.txt
/bar/ {
  if ($0 ~ /baz/) {
    # skip
  } 
  else {
    print "found bar: " $0
  } 
}

/foo/ {
  print "found foo: " $0    
}

If you are on a line which contains the pattern /bar/ and if the condition ($0 ~ /baz/) occurs you can simply do nothing and skip to the next pattern which is /foo/
Output:

$ awk -f david_klein.awk david_klein.txt
found bar: line 1 bar
found foo: line 3 foo bar baz

Hi

microm, I think the OP wants to return early from a more complex condition hell.
[pre][small]
pattern1 {
many lines, nested loops etc.

if (condition) {
many lines, nested loops etc.

if (condition) {
many lines, nested loops etc.

if (condition) {
Skip_rest_of_pattern1_and_continue_with_pattern2
}

many lines, nested loops etc.
} else {
many lines, nested loops etc.
}

many lines, nested loops etc.
} else {
many lines, nested loops etc.
}

many lines, nested loops etc.
}

pattern2 {
more code
}
[/small][/pre]
Personally I would think about moving pattern1's action in a dummy function from where to be able to [tt]return[/tt] in any desired moment, then call only that dummy function on pattern1. Ugly, clumsy, efficient.
