NAME

textconv - optex module to replace document file by its text contents

VERSION

Version 1.07

SYNOPSIS

optex command -Mtextconv

optex command -Mtc (alias module)

optex command -Mtextconv::load=pandoc

DESCRIPTION

This module replaces several sort of filenames by node representing its text information. File itself is not altered.

For example, you can check the text difference between MS word files like this:

$ optex diff -Mtextconv OLD.docx NEW.docx

If you have symbolic link named diff to optex, and following setting in your ~/.optex.d/diff.rc:

option default --textconv
option --textconv -Mtextconv $<move>

Next command simply produces the same result.

$ diff OLD.docx NEW.docx
