When opening a MIME message with parts other +than plain text or non-MIME messages with a content type other than plain text +the macro automatically converts these parts to plain text provided that the +conversion has been allowed in the configuration there is an appropriate entry +in the mailcap file. Parts with multipart/alternative content type are handled +intelligently by preferring the text part if available and falling back to +converting another part for which automatic conversion has been enabled. The +macro can process arbitrarily nested parts with message/rfc822, +multipart/alternative, multipart/mixed, multipart/digest, multipart/related, +and multipart/signed content type. It also features full support for mailcap +files as defined by RFC 1524, including substitutions. Furthermore, it +provides methods for selecting any MIME part for saving or viewing with an +external viewer and for toggling between the processed and raw message. + +Usage +----- + +The slrn MIME support macro can be used by including it in the .slrnrc user +initialization file via the `interpret` command, e.g. provided that the file +mime-support.sl is located in one of the directories specified by the +macro_directory configuration variable: + + interpret "mime-support.sl" + +The macro can be configured through the following slang variables: + +MIMESupport->config.auto_view +: Array that specifies which content types may be automatically converted to + plain text when opening a MIME message. + +It provides the following methods: + +MIMESupport->mime_save_part() +: Displays a dialog allowing the user to save a MIME part. + +MIMESupport->mime_view_part() +: Displays a dialog allowing the user to view a MIME part using the command + specified in the mailcap entry corresponding to its content type. + +MIMESupport->mime_toggle_view() +: Toggles between the processed and raw form. + +The following environment variables are observed: + +TMPDIR +: Path for temorary files when invoking the command specified in a mailcap + entry. + +PAGER +: The pager used for handling the output of a command specified in a mailcap + entry which contains a copiousoutput flag. + +Contact +------- + +Please send any feedback, translations or bug reports via email to +<guido+slrn@berhoerster.name>. + +Bug Reports +----------- + +When sending bug reports, please always mention the exact version of the +macro with which the issue occurs as well as the version of slrn, slang and +the operating system you are using and make sure that you provide sufficient +information to reproduce the issue and include any input, output, any error +messages and slang stack traces. + +License +------- + +Except otherwise noted, all files are Copyright (C) 2013 Guido Berhoerster and +distributed under the following license terms: + +Copyright (C) 2013 Guido Berhoerster <guido+slrn@berhoerster.name> + +This file incorporates work from the file mime.sl distributed with slrn under +the terms of the GNU General Public Licens version 2 or later. + +Copyright (C) 2012 John E.
