 # This is a test script for the Katepart Bash Syntax Highlighting by
 #       Wilbert Berendsen.  This is not runnable !!!
 
 
 # The highlighting recognizes basic types of input, and has a few special cases that
 # are all in FindCommands.  The main objective is to create really proper nesting of
 # (multiline) strings, variables, expressions, etc.
 
 
 
 # ============== Tests: ===============
 
 # basic types:
 echo 'single quoted string'
 echo "double quoted string"
 echo $'string with esc\apes\x0din it'
 echo $"string meant to be translated"
 echo "$"
 
 
 # comments:
 # this is a comment
 #this too
 echo this is#nt a comment
 dcop kate EditInterface#1 #this is
 grep -e "^default/linux/amd64/" |\ #this is not a comment but #this is
 mkdir this\ isnt\ #a\ comment
 mkdir this\ isnt\\\;#a\ comment
