WHAT IT DOES
This script tries to recognise an attachment by using the 'file'
command and/or the file extension and then uses the available
- utilities to make an effort to display it as text. For example
- .doc antiword -w 72
- .txt, .diff, .c, .h,
- .ic. .ec, .cc, .sh,
- .sed, .awk cat
- .html txt2htm or text2html
- .xls, .sxc, .csv xlscat -L
- .rtf rtf2text
- .pdf pdf2text %f -
- .odt ooo2txt
- .pl, .pm perltidy -st -se or cat
- .bz2 bzip2 -d < %f | strings
+ utilities to make an effort to display it as text.
+
+ $ textview.pl --list
+
+ will show available conversion, the top:
+
+ .awk cat
+ .bin strings
+ .bz2 bzip2 -d < %f | strings
+ .c cat
+ .cc cat
+ .csv xlscat -L
+
+ If there are multiple alternatives available, they are listed in
+ the ordder they are tried, like for .xls:
+
+ .xls xlscat -L
+ .xls catdoc -x -dutf-8
+ .xls wvText
HOW TO USE IT
Go to /Configuration/Message View/External Programs and enter the
Now when you right-click an attachment and choose 'Display as text'
this script will be invoked.

+ xlscat comes with the perl module Spreadsheet::Read, which is a
+ wrapper module over several parsers and supports ods, sxc, csv, xls,
+ xlsx, and sq. See https://metacpan.org/release/Spreadsheet-Read
