Top Forums UNIX for Dummies Questions & Answers Removing double spaces in code Post 302652905 by figaro on Friday 8th of June 2012 03:31:43 AM

Thank you for your answer. Your code also replaces double spaces prior to the comment delimiter ("//"). So that the following:
Code:
   this is some   code    // code comment

turns into the following
Code:
   this is some code // code comment

In brief there are the following cases:
Code:
this is code line   1
    this is code line  2   // code comment
    this is code line  3   // there may be good reasons to keep the double space in the   comment
    this is code line   4  // triple spaces should turn into one space as well

and should turn into the following:
Code:
this is code line 1
    this is code line 2   // code comment
    this is code line 3   // there may be good reasons to keep the double space in the   comment
    this is code line 4  // triple spaces should turn into one space as well

Grateful to anyone looking into this.

NAME

       viewperl - quickly view syntax highlighted Perl code

SYNOPSIS

       viewperl [OPTION]... FILE...

DESCRIPTION

       View a Perl source code file, syntax highlighted.

       -c, --code=CODE
	      view CODE, syntax highlighted

       -l, --lines
	      display line numbers

       -L, --no-lines
	      supress display of line numbers (default)

       -m, --module=FILE
	      consider FILE the name of a module, not a file name

       -n, --name
	      display the name of each file (default)

       -N, --no-name
	      supress display of file names (implied by --no-reset)

       -p, --pod
	      display inline POD documentation (default)

       -P, --no-pod
	      hide POD documentation (line numbers still increment)

       -r, --reset
	      reset formatting and line numbers each file (default)

       Note that module names should be given as they would appear after a Perl `use' or `require' statement.  `Getopt::Long', for example.

       Each string given using -c is considered a different file, so line number and formatting resets will apply.
