COM)25#26# ChangeLog :27#28# 10/08/2008 - Initial version (v0.1)29# 15/08/2008 - Script takes two arguments [second optional] now and can be30# used independently to extract text from docx file. It accepts31# docx file directly, instead of xml file.32# 18/08/2008 - Added support for center and right justification of text that33# fits in a line 80 characters wide (adjustable).34# 03/09/2008 - Fixed the slip in usage message.35# 12/09/2008 - Slightly changed the script invocation and argument handling36# to incorporate some of the shell script functionality here.37# Added support to handle embedded urls in docx document.38# 23/09/2008 - Changed #! line to use /usr/bin/env - good suggestion from39# Rene Maroufi (info>AT<maroufi>DOT<net) to reduce user work40# during installation.41# 31/08/2009 - Added support for handling more escape characters.42# Using OS specific null device to redirect stderr.43# Saving text file in binary mode.44# 03/09/2009 - Updations based on feedback/suggestions from Sergei Kulakov45# (sergei>AT<dewia>DOT<com).46# - removal of non-document text in between TOC related tags.47# - display of hyperlink alongside linked text user controlled.48# - some character conversion updates49# 05/09/2009 - Merged cjustify and rjustify into single subroutine justify.50# Added more character conversions.51# Organised conversion mappings in tabular form for speedup and52# easy maintenance.53# Tweaked code to reduce number of passes over document content.54# 10/09/2009 - For leaner text experience, hyperlink is not displayed if55# hyperlink and hyperlinked text are same, even if user has56# enabled hyperlink display.57# Improved handling of short line justification. Many58# justification tag patterns were not captured earlier.59# 11/09/2009 - A directory holding the unzipped content of .docx file can60# also be specified as argument to the script, in place of file.61# 17/09/2009 - Removed trailing slashes from input directory name.62# Updated unzip command invocations to handle path names63# containing spaces.64# 01/10/2009 - Added support for configuration file.65# 02/10/2009 - Using single quotes to specify path for unzip command. 66# 04/10/2009 - Corrected configuration option name lineIndent to listIndent.67# 11/12/2011 - Configuration variables now begin with config_ .68# Configuration file is looked for in HOME directory as well.69# Added a check for existence of unzip command.70# Superscripted cross-references are placed within [...] now.71# Fixed bugs #3003903, #3082018 and #3082035.72# Fixed nullDevice for Cygwin.73# 12/12/2011 - Configuration file is also looked for in /etc, default74# location for Unix-ish systems.75# 22/12/2011 - Added ' and " to docx specific escape characters76# conversions. [Bug #3463033]77# 24/12/2011 - Improved handling of special (non-text) characters, along with78# support for more non-text characters.79# 05/01/2012 - Configuration file is now looked for in current directory,80# user configuration directory and system configuration81# directory (in the specified order). This streamlining allows82# for per user configuration file even on Windows.83# 14/01/2012 - Wrong code was committed during earlier fixing of nullDevice84# for Cygwin, fixed that.85# Usage is extended to accept docx file from standard input.86# "-h" has to be given as the first argument to get usage help.87# Added new configuration variable "config_tempDir".88# 14/03/2014 - Remove deleted text from output. This effects in case changes89# are being tracked in docx document. Patch was contributed by90# William Parsons (wbparsons>AT<cshore>DOT<com).91# Removed experimental config option config_exp_extra_deEscape.92# 27/03/2014 - Remove non-document_text content marked by wp/wp14 tags.93# 07/04/2014 - Added support for handling lists (bullet, decimal, letter,94# roman) along with (attempt at) indentation.95# Added new configuration variable config_twipsPerChar.96# Removed configuration variable config_listIndent.97# 14/04/2014 - Fixed list numbering - lvl start value needs to be considered.98# Improved list indentation and corresponding code.99# 27/04/2014 - Improved paragraph content layout/indentation.100# 13/05/2014 - Added new configuration variable config_unzip_opts. Users can101# now use unzipping programs like 7z, pkzipc, winzip as well.102#103 104 105#106# The default settings below can be overridden via docx2txt.config in current107# directory/ user configuration directory/ system configuration directory.108#109 110our $config_unzip = '/usr/bin/unzip'; # Windows path like 'C:/path/to/unzip.exe'111our $config_unzip_opts = '-p'; # To extract file on standard output112 113our $config_newLine = "\n"; # Alternative is "\r\n".114our $config_lineWidth = 80; # Line width, used for short line justification.115our $config_showHyperLink = "N"; # Show hyperlink alongside linked text.116our $config_tempDir; # Directory for temporary file creation.117our $config_twipsPerChar = 120; # Approx mapping for layout purpose.118 119 120#121# Windows/Non-Windows specific settings.
