Top Forums Shell Programming and Scripting A better way to compare text length percentage? Post 303046101 by bedtime on Thursday 23rd of April 2020 07:52:48 PM
Old 04-23-2020
Thank you all for you solutions. I ended up going with vegersh99's solution as it was the most brief. I liked RudiC's mathmatics with the inverse equation.


Since I cannot have 'division by zero' errors, I added the 'if' statement near the end. Found out that shell doesn't like to compare numbers with decimals so added the int() function as well:

Code:
echo ${#text1} ${#text2} | awk '{a=b=$1;($1>$2)?a=$2:b=$2;if(a*b){print int(100/a*b)}}'


Would really like to figure out how to get this to do the equation so as not to have the 'division by zero' error when one or two variables have an empty string. I've tried a bunch of things such as adding '1' to each variable and trying to make it up elsewhere, but each time the values are incorrect.



Anyways, for now, it's more concise, and it's being used in the code.


Thanks everyone!

svn::web::diff

SVN::Web::Diff(3pm)					User Contributed Perl Documentation				       SVN::Web::Diff(3pm)

NAME

       SVN::Web::Diff - SVN::Web action to show differences between file revisions

SYNOPSIS

       In config.yaml

	 actions:
	   ...
	   diff:
	     class: SVN::Web::Diff
	   ...

DESCRIPTION

       Returns the difference between two revisions of the same file.

CONFIGURATION

       The following configuration options may be specified in config.yaml.

       max_diff_size
	   If showing the diff (see "show_diff"), this determines the maximum size of the diff that will be shown.  If the size of the generated
	   diff (in bytes) is larger than this figure then it is not shown.

	   Defaults to 200,000 bytes.

OPTIONS

       rev1    The first revision of the file to compare.

       rev2    The second revision of the file to compare.

       revs    A list of two or more revisions.  If present, the smallest number in the list is assigned to "rev1" (overriding any given "rev1"
	       value) and the largest number in the list is assigned to "rev2" (overriding any given "rev2" value).

	       In other words:

		   ...?rev1=5;rev2=10

	       is equal to:

		   ...?revs=10;revs=5

	       This supports the "diff between arbitrary revisions" functionality.

       mime    The desired output format.  The default is "html" for a diff marked up in HTML.	The other allowed value is "text", for a plain
	       text unified diff.

TEMPLATE VARIABLES

       at_head Boolean, indicating whether or not we're currently diffing against the youngest revision of this file.

       context Always "file".

       rev1    The first revision of the file to compare.  Corresponds with the "rev1" parameter, either set explicitly, or extracted from "revs".

       rev2    The second revision of the file to compare.  Corresponds with the "rev2" parameter, either set explicitly, or extracted from
	       "revs".

       diff    An SVN::Web::DiffParser object that contains the text of the diff.  Call the object's methods to format the diff.

       diff_size
	       The size of the generated diff (before parsing).

       max_diff_size
	       The configured maximum diff size.

EXCEPTIONS

       (cannot diff nodes of different types: %1 %2 %3)
	   The given path has different node types at the different revisions.	This probably means a file was added, deleted, and then re-added
	   as a directory at a later date (or vice-versa).

       (path %1 is a directory at rev %2)
	   The user has tried to diff two directories.	This is not currently supported.

       (path %1 does not exist in revision %2)
	   The given path is not present in the repository at the given revision.

       (two revisions must be provided)
	   No revisions were given to diff against.

       (rev1 and rev2 must be different)
	   Either only one revision number was given, or several were given, but they're the same number.
