Remove ":" and join lines in outline file
I have a vim outliner file like this:

PHP Code:
Title   
        title 2 
                :Testing now
                :testing 2
                :testing 3
        title 3 
                :testing
                :ttt
                :ttg 
Is there a way to use a script or command to remove the ":" in front of the the text blocks and join these lines to give this output?

PHP Code:
Title   
        title 2 
                Testing now testing 2 testing 3
        title 3 
                testing ttt ttg

Try this,
Code:
 awk '{if(/:/) {sub(/:/,"");printf "%s",$0}else{printf "\n%s\n",$0}} END {print "\n"}' inputfile

Try this:
Code:
awk '/:/{if(s){$1=$1};s=s?s FS $0:$0; next}
s{gsub(":", "", s); print s; s=""}1
END{if(s)gsub(":", "", s);print s}
' file

' file

Thanks for the suggestions! This works perfectly as it also removes the extra whitespace between the words.

Code:
awk 'END{f(s)}function f(s){if(s)gsub(":",x,s);print s}/:/{if(s){$1=$1};s=((s)?s FS:x)$0;next}s{f(s);s=""}1' file

A spin-out of Franklin solution
