Re^5: Mandatory indenting

[atcroft]

An adaptation of this script might work in that regard. It was a shell script I hacked together to reformat occasionally as I worked on things. Given one or more files on the command line, it looks to see if there is a .tdy version of the file present (creating an empty one if not), checks if the current version and the .tdy version differ, and if so, performs a tidy (setting the lines 123 characters-personal preference), not replacing the original if a .ERR file was produced. The .tdy file was also left in place for future comparison.

#!/bin/bash

PERLTIDY='/usr/local/bin/perltidy -l 123 '
TOUCH=/bin/touch
DIFF=/usr/bin/diff
WC=/usr/bin/wc
CP=/bin/cp

if [ $# -gt 0 ]
then
  echo Command line: $0 $@

  for file in $@ 
  do 
    if [ ! -e $file.tdy ] 
    then 
      $TOUCH $file.tdy 
    fi
    if [ `$DIFF -q $file $file.tdy | $WC -l` -gt 0 ] 
    then 
      $PERLTIDY $file 
      if [ -e $file.ERR ]
      then
        echo Error detected-not replacing
      else
        $CP -v $file.tdy $file
      fi
    else 
      echo Skipping $file - perltidy on file not necessary 
    fi
  done
else
  echo Usage: $0 filename
fi

Update (20 Jan 2004): Added absolute paths to utilities used, to prevent issues with pathing.
