  27 If Mutt was compiled with compressed folders support (by running the
  28 <span class="emphasis"><em>configure</em></span> script with the
  29 <span class="emphasis"><em>--enable-compressed</em></span> flag), Mutt can open folders
  30 stored in an arbitrary format, provided that the user has a script to
  31 convert from/to this format to one of the accepted.
  32
  33 The most common use is to open compressed archived folders e.g. with
  34 gzip.
  35
  36 In addition, the user can provide a script that gets a folder in an
  37 accepted format and appends its context to the folder in the
  38 user-defined format, which may be faster than converting the entire
  39 folder to the accepted format, appending to it and converting back to
  40 the user-defined format.
  41
  42 There are three hooks defined (<a class="link" href="index.html#open-hook" title="1.1. Open a compressed mailbox for reading">open-hook</a>, <a class="link" href="index.html#close-hook" title="1.2. Write a compressed mailbox">close-hook</a> and <a class="link" href="index.html#append-hook" title="1.3. Append a message to a compressed mailbox">append-hook</a>) which define commands to
  43 uncompress and compress a folder and to append messages to an existing
  44 compressed folder respectively.
  45
  46 For example:
  47
  48 </p><pre class="screen">
  49 open-hook \\.gz$ "gzip -cd %f &gt; %t"
  50 close-hook \\.gz$ "gzip -c %t &gt; %f"
  51 append-hook \\.gz$ "gzip -c %t &gt;&gt; %f"
  52 </pre><p>
  53
  54 You do not have to specify all of the commands. If you omit <a class="link" href="index.html#append-hook" title="1.3. Append a message to a compressed mailbox">append-hook</a>, the folder will be open and
  55 closed again each time you will add to it. If you omit <a class="link" href="index.html#close-hook" title="1.2. Write a compressed mailbox">close-hook</a> (or give empty command) , the
  56 folder will be open in the mode. If you specify <a class="link" href="index.html#append-hook" title="1.3. Append a message to a compressed mailbox">append-hook</a> though you'll be able to
  57 append to the folder.
  58
  59 Note that Mutt will only try to use hooks if the file is not in one of
  60 the accepted formats. In particular, if the file is empty, mutt
  61 supposes it is not compressed. This is important because it allows the
  62 use of programs that do not have well defined extensions. Just use
  63 "." as a regexp. But this may be surprising if your
  64 compressing script produces empty files. In this situation, unset
  65 <a class="link" href="reference.html#save-empty" title="3.252. save_empty">$save_empty</a>, so that
  66 the compressed file will be removed if you delete all of the messages.

  68 Usage: <code class="literal">open-hook</code> <span class="emphasis"><em>regexp</em></span> "<span class="emphasis"><em>command</em></span>"
  69
  70 The <span class="emphasis"><em>command</em></span> is the command that can be used for
  71 opening the folders whose names match <span class="emphasis"><em>regexp</em></span>.
  72
  73 The <span class="emphasis"><em>command</em></span> string is the printf-like format
  74 string, and it should accept two parameters: %f, which is
  75 replaced with the (compressed) folder name, and %t which is
  76 replaced with the name of the temporary folder to which to write.
  77
  78 %f and %t can be repeated any number of times in the
  79 command string, and all of the entries are replaced with the
  80 appropriate folder name. In addition, %% is replaced by
  81 %, as in printf, and any other %anything is left as is.
  82
  83 The <span class="emphasis"><em>command</em></span> should <span class="bold"><strong>not</strong></span> remove the original compressed file.  The
  84 <span class="emphasis"><em>command</em></span> should return non-zero exit status if it
  85 fails, so mutt knows something's wrong.

  96 Usage: <code class="literal">close-hook</code> <span class="emphasis"><em>regexp</em></span> "<span class="emphasis"><em>command</em></span>"
  97
  98 This is used to close the folder that was open with the <a class="link" href="index.html#open-hook" title="1.1. Open a compressed mailbox for reading">open-hook</a> command after some changes were
  99 made to it.
 100
 101 The <span class="emphasis"><em>command</em></span> string is the command that can be
 102 used for closing the folders whose names match
 103 <span class="emphasis"><em>regexp</em></span>. It has the same format as in the <a class="link" href="index.html#open-hook" title="1.1. Open a compressed mailbox for reading">open-hook</a> command. Temporary folder in this
 104 case is the folder previously produced by the <a class="link" href="index.html#open-hook" title="1.1. Open a compressed mailbox for reading">open-hook</a> command.
 105
 106 The <span class="emphasis"><em>command</em></span> should <span class="bold"><strong>not</strong></span> remove the decompressed file. The
 107 <span class="emphasis"><em>command</em></span> should return non-zero exit status if it
 108 fails, so mutt knows something's wrong.

 110 Example:
 111
 112 </p><pre class="screen">
 113 close-hook \\.gz$ "gzip -c %t &gt; %f"
 114 </pre><p>
 115
 116 If the <span class="emphasis"><em>command</em></span> is empty, this operation is
 117 disabled for this file type, and the file can only be open in the
 118 read-only mode.
 119
 120 <a class="link" href="index.html#close-hook" title="1.2. Write a compressed mailbox">close-hook</a> is not called when you
 121 exit from the folder if the folder was not changed.
 122 </p></div><div class="sect2" lang="en" xml:lang="en"><div class="titlepage"><div><div><h3 class="title"><a id="append-hook"></a>1.3. Append a message to a compressed mailbox</h3></div></div></div><p>
 123 Usage: <code class="literal">append-hook</code> <span class="emphasis"><em>regexp</em></span> "<span class="emphasis"><em>command</em></span>"
 124
 125 This command is used for saving to an existing compressed folder.  The
 126 <span class="emphasis"><em>command</em></span> is the command that can be used for
 127 appending to the folders whose names match
 128 <span class="emphasis"><em>regexp</em></span>. It has the same format as in the <a class="link" href="index.html#open-hook" title="1.1. Open a compressed mailbox for reading">open-hook</a> command.  The temporary folder in
 129 this case contains the messages that are being appended.
 130
 131 The <span class="emphasis"><em>command</em></span> should <span class="bold"><strong>not</strong></span> remove the decompressed file. The
 132 <span class="emphasis"><em>command</em></span> should return non-zero exit status if it
 133 fails, so mutt knows something's wrong.
 134
 135 Example:
 136
 137 </p><pre class="screen">
 138 append-hook \\.gz$ "gzip -c %t &gt;&gt; %f"
 139 </pre><p>
 140
 141 When <a class="link" href="index.html#append-hook" title="1.3. Append a message to a compressed mailbox">append-hook</a> is used, the folder
 142 is not opened, which saves time, but this means that we can not find
 143 out what the folder type is. Thus the default (<a class="link" href="reference.html#mbox-type" title="3.117. mbox_type">$mbox_type</a>) type is always
 144 supposed (i.e.  this is the format used for the temporary folder).
 145
 146 If the file does not exist when you save to it, <a class="link" href="index.html#close-hook" title="1.2. Write a compressed mailbox">close-hook</a> is called, and not <a class="link" href="index.html#append-hook" title="1.3. Append a message to a compressed mailbox">append-hook</a>. <a class="link" href="index.html#append-hook" title="1.3. Append a message to a compressed mailbox">append-hook</a> is only for appending to
 147 existing folders.
 148
 149 If the <span class="emphasis"><em>command</em></span> is empty, this operation is
 150 disabled for this file type. In this case, the folder will be open and
 151 closed again (using <a class="link" href="index.html#open-hook" title="1.1. Open a compressed mailbox for reading">open-hook</a> and
 152 <a class="link" href="index.html#close-hook" title="1.2. Write a compressed mailbox">close-hook</a>respectively) each time you
 153 will add to it.

 155 The compressed folders support can also be used to handle encrypted
 156 folders. If you want to encrypt a folder with PGP, you may want to use
 157 the following hooks:
 158
 159 </p><pre class="screen">
 160 open-hook  \\.pgp$ "pgp -f &lt; %f &gt; %t"
 161 close-hook \\.pgp$ "pgp -fe YourPgpUserIdOrKeyId &lt; %t &gt; %f"
 162 </pre><p>
 163
 164 Please note, that PGP does not support appending to an encrypted
 165 folder, so there is no append-hook defined.
 166
 167 If you are using GnuPG instead of PGP, you may use the following hooks
 168 instead:
 169
 170 </p><pre class="screen">
 171 open-hook  \\.gpg$ "gpg --decrypt &lt; %f &gt; %t"
 172 close-hook \\.gpg$ "gpg --encrypt --recipient YourGpgUserIdOrKeyId &lt; %t &gt; %f"
 173 </pre><p>
 174
 175 <span class="bold"><strong>Note:</strong></span> the folder is temporary stored
 176 decrypted in the /tmp directory, where it can be read by your system
 177 administrator. So think about the security aspects of this.
