Consequently, if replying to a multipart, non-plain text message, and your repl filter includes the body of the message being replied to, all the MIME formatting is included, which can be messing for binary data, like images, and for quoted-printable text.</p> <p>mha-mhedit is designed to be used as the <code>repl</code> editor:</p> <pre> repl -editor mha-mhedit</pre> <p>mha-mhedit is designed to functional transparently. mha-mhedit formats and quotes the reply-to message body for editing in the message draft. After the formatting is complete, mha-mhedit invokes your regular editor for final composition.</p> <p>mha-mhedit does its job by using MHonArc, <<a href="http://www.mhonarc.org">http://www.mhonarc.org</a>>, with a specially crafted MHonArc resource file, and by using a text-based HTML viewer, like w3m, <<a href="http://w3m.sourceforge.net/">http://w3m.sourceforge.net/</a>>. Of course, a tool can be developed that does not depend on these types of tools, but I did not feel like developing one and these work well for what I wanted.</p> <p>mha-mhedit can be invoke by default when using <code>repl</code> by having the following in your <code>.mh_profile</code>:</p> <pre> repl: -editor mha-mhedit</pre> <p>However, since using mha-mhedit adds some extra initial overhead before your regular editor is invoked, you may choose to define a shell alias instead:</p> <pre> (t)csh: alias mrepl repl -editor mha-mhedit</pre> <pre> bash: alias mrepl="repl -editor mha-mhedit"</pre> <p>Therefore, if replying to a MIME messages, you enter <code>mrepl</code> at your shell prompt and continue to use <code>repl</code> for plain text messages.</p> <p><strong>Note:</strong> It is recommended to have something like the following in your <code>.mh_profile</code>:</p> <pre> mha-mhedit-next: <your-editor></pre> <p>This way, at the <code>What now?</code> prompt, if you enter <code>edit</code>, it will invoke your regular editor again instead of calling mha-mhedit, which will cause all your edits to be lost.</p> <p> </p> <hr /> <h1><a name="options">OPTIONS</a></h1> <p>Options can be defined in your <code>.mh_profile</code> like any other MH/nmh component. For example:</p> <pre> mha-mhedit: -editor vim</pre> <p>The following options are available:</p> <dl> <dt><strong><a name="item_%2deditor_editor">-editor <em>editor</em></a></strong><br /> </dt> <dd> Text editor to invoke at the end. If not specified, the value of the Editor profile component, the EDITOR environment variable, or <code>vi</code> is used. </dd> <dd> <p>Arguments to the editor can be defined by setting the <a href="#item_mha%2dmhedit%2deditor"><code>mha-mhedit-editor</code></a> profile component. For example, if your editor is set to <code>vim</code>, the following can be added to your <code>.mh_profile</code> to have vim start at the end of your reply:</p> </dd> <dd> <pre> mha-mhedit-vim: +</pre> </dd> <p></p> <dt><strong><a name="item_%2dhtmlconv_command">-htmlconv <em>command</em></a></strong><br /> </dt> <dd> Command that converts HTML to plain text. The command must be able to take HTML from stdin and dump plain text to stdout. If the command requires arguments. If not specified, then <a href="#item_w3m"><code>w3m</code></a> is used. </dd> <dd> <p>You can define arguments to give the specified converter by defining the <a href="#item_mha%2dmhedit%2dhtmlconv"><code>mha-mhedit-htmlconv</code></a> profile component in your <code>.mh_profile</code>. For example, the following represents the default arguments used if <code>-htmlconv</code> is <a href="#item_w3m"><code>w3m</code></a>:</p> </dd> <dd> <pre> mha-mhedit-w3m: -dump -cols 76 -T text/html</pre> </dd> <dd> <p>The following works well if <code>-htmlconv</code> is set to <code>lynx</code>:</p> </dd> <dd> <pre> mha-mhedit-lynx: -stdin -dump -force_html -nolist -width=76</pre> </dd> <p></p> <dt><strong><a name="item_%2dlinelen_number">-linelen <em>number</em></a></strong><br /> </dt> <dd> Maxium line length of formated reply text.

If not specified, the file <code>mha-repl.mrc</code> in your MH/nmh directory. </dd> <dd> <p><strong>Note:</strong> If a resource file is not found, mha-mhedit aborts execution.

If not specified, <code>mhonarc</code> is used. </dd> <dd> <p>You can define extra arguments to give <code>mhonarc</code> by defining the <a href="#item_mha%2dmhedit%2dmhonarc"><code>mha-mhedit-mhonarc</code></a> profile component in your <code>.mh_profile</code>. However, I'm unsure if you will ever need to.</p> </dd> <p></p> <dt><strong><a name="item_%2dquotechars_chars">-quotechars <em>chars</em></a></strong><br /> </dt> <dd> List of characters denoting the start of a quoted line in a message. This option affects is used during line wrapping when detecting for quoted lines. </dd> <dd> <p>The default value is <code>></code>.</p> </dd> <p></p> <dt><strong><a name="item_%2dquoteprefix_string">-quoteprefix <em>string</em></a></strong><br /> </dt> <dd> String to prepend to each line of text being responded to.

After that, mha-mhedit reads up-to the next 5 lines for potential inclusion. The body preamble in my replcomps takes up 2 lines (there is a trailing blank line that may not be easily noticed above). Therefore, mha-mhedit will preserve it. The third line will be the start of quoted text. mha-mhedit sees this, and stops reading the draft.</p> <p>Now, if I plan to make mha-mhedit my default repl editor, it will be more efficient if I remove the message body quoting since mha-mhedit will ignore and overwrite anyway.</p> <p></p> <li></li> Currently, no temporary files should be generated. However, this depends on the version of mhonarc you are using, the type of message being replied to, and any edits you may make to the mhonarc resource file. <p>It may be possible that by-product files, like attachments, could be created. If so, manual deletion of the files in <code>-tmpdir</code> will be required.</p> <p></p></ul> <p> </p> <hr /> <h1><a name="files">FILES</a></h1> <dl> <dt><strong><a name="item_%24home%2f%2emh_profile"><code>$HOME/.mh_profile</code></a></strong><br /> </dt> <dd> Profile definitions. </dd> <p></p> <dt><strong><a name="item_%3cmh%2ddir%3e%2fmha%2drepl%2emrc"><code><mh-dir>/mha-repl.mrc</code></a></strong><br /> </dt> <dd> MHonArc resource file.
