|
|
# This script is a text viewer designed to be used with claws-mail actions
|
|
# Set up an action with the command line: textviewer.sh %p |
|
|
#
|
|
# The script will try to detect file type automatically, and then
|
|
# invokes a relevant program to print the file in plain text to
|
|
# the standard output.
|
|
#
|
|
# From v 0.9.7claws7, claws-mail sets the temporary file
|
|
# of a part to XXXXXX.mimetmp.[filename of attachment]
|
|
# This means we can use the extension of the filename for checking.
|
|
# Also use the program 'file' if that fails.
|
|
#
|
|
# To extend the script just follow the patterns that already exist, or
|
|
# contact the author if you have problems.
