shtpl - shell templating system

Syntax:
#% shell-command
#%# comment
#%include file
#%raw 
#%end raw
#%incraw file (include raw file)
#slurp        (removes trailing newline)
%$            (masks $)    

Options:
-ass/--allow-subshell: does not mask $(, ´
-o  /--optimize      : minimize printf usage

Example usage:
sh -c "$( shtpl [Options...] template )"
shtpl [Options...] template | ( . /dev/stdin )

Should work with busybox ash, dash, bash, ksh and zsh.

Installation:

sudo make install

Example Templates:

$ cat testfile
  #%include testfile2
  
  
  #%incraw testraw
   
  #% for i in first "second\"" third; do 
  #% str=super; [ "$i" = "third" ] && str="not so super" 
     blubber test $i ist $str, #slurp
     keine'\\" frage
  #% done 
    blub!
  
  #%raw
  #%echo Hello
  #%end raw

  #%#include testfile2

$ cat testfile2
  #% date="$( date )"
     $date
     $( date )
     ` date `
     ./*.sh 
     <( ls )
     %$date
 
 $ cat testraw 
 Blubber blubb
 blub
 blubber blub
 $date
 $
 #% echo blub
 ` date `
 $(

shtpl's output:

$ shtpl testfile
date="$( date )"
printf "%s\n" "   $date"
printf "%s\n" "   \$( date )"
printf "%s\n" "   \` date \`"
printf "%s\n" "   ./*.sh "
printf "%s\n" "   <( ls )"
printf "%s\n" "   \$date"
printf "%s\n" ""
printf "%s\n" ""
printf "%s\n" "Blubber blubb"
printf "%s\n" "blub"
printf "%s\n" "blubber blub"
printf "%s\n" "\$date"
printf "%s\n" "\$"
printf "%s\n" "#% echo blub"
printf "%s\n" "\` date \`"
printf "%s\n" "\$("
printf "%s\n" ""
printf "%s\n" ""
 for i in first "second\"" third; do 
 str=super; [ "$i" = "third" ] && str="not so super" 
printf "%s" "   blubber test $i ist $str, "
printf "%s\n" "   keine'\\\\\" frage"
 done 
printf "%s\n" "  blub!"
printf "%s\n" ""
printf "%s\n" "#%echo Hello"
printf "%s\n" ""
#include testfile2

Results in:

$ sh -c "$( shtpl testfile )"
