+Single quotes (“<span class="quote">'</span>”) and double quotes (“<span class="quote">"</span>”) can be used to quote strings
which contain spaces or other special characters. The difference between
the two types of quotes is similar to that of many popular shell programs,
namely that a single quote is used to specify a literal string (one that is
not interpreted for shell variables or quoting with a backslash [see
next paragraph]), while double quotes indicate a string for which

It is also possible to substitute the output of a Unix command in an
initialization file. This is accomplished by enclosing the command in
-backquotes (``). For example,
-
-</p><pre class="screen">
-my_hdr X-Operating-System: `uname -a`
-</pre><p>
-
-The output of the Unix command ``uname -a'' will be substituted before the
-line is parsed. Note that since initialization files are line oriented, only
+backticks (``). In <a class="xref" href="configuration.html#ex-rc-backtick" title="Example 3.5. Using external command's output in configuration files">Example 3.5, “Using external command's output in configuration files”</a>, the output of the
+Unix command “<span class="quote">uname -a</span>” will be substituted before the
+line is parsed.
+Since initialization files are line oriented, only
the first line of output from the Unix command will be substituted.

-Both environment variables and mutt variables can be accessed by
-prepending ``$'' to the name of the variable. For example,
-</p><pre class="screen">

+By defining your spam patterns with the <span class="command"><strong>spam</strong></span> and <code class="literal">nospam</code>
commands, you can <span class="emphasis"><em>limit</em></span>, <span class="emphasis"><em>search</em></span>, and <span class="emphasis"><em>sort</em></span> your
mail based on its spam attributes, as determined by the external
filter. You also can display the spam attributes in your index
-display using the <code class="literal">%H</code> selector in the <a href="reference.html#index-format" title="3.100. index_format">$index_format</a> variable. (Tip: try <code class="literal">%?H?[%H] ?</code>

to display spam tags only when they are defined for a given message.)
</p><p>

-the <code class="literal">spam</code> command. <span class="emphasis"><em>pattern</em></span> should be a regular expression
+the <span class="command"><strong>spam</strong></span> command. <span class="emphasis"><em>pattern</em></span> should be a regular expression

-``spam attribute'' (unless it also matches a <code class="literal">nospam</code> pattern -- see
+matches this regular expression, it will receive a “<span class="quote">spam tag</span>” or
+“<span class="quote">spam attribute</span>” (unless it also matches a <span class="command"><strong>nospam</strong></span> pattern — see
below.) The appearance of this attribute is entirely up to you, and is
governed by the <span class="emphasis"><em>format</em></span> parameter. <span class="emphasis"><em>format</em></span> can be any static
text, but it also can include back-references from the <span class="emphasis"><em>pattern</em></span>
-expression. (A regular expression ``back-reference'' refers to a
+expression. (A regular expression “<span class="quote">back-reference</span>” refers to a
sub-expression contained within parentheses.) <code class="literal">%1</code> is replaced with
the first back-reference in the regex, <code class="literal">%2</code> with the second, etc.
</p><p>
+To match spam tags, mutt needs the corresponding header information
+which is always the case for local and POP folders but not for IMAP in
+the default configuration. Depending on the spam header to be analyzed,
+<a class="link" href="reference.html#imap-headers" title="3.99. imap_headers">$imap_headers</a> may need
+to be adjusted.
+</p><p>
If you're using multiple spam filters, a message can have more than
-one spam-related header. You can define <code class="literal">spam</code> patterns for each
+one spam-related header. You can define <span class="command"><strong>spam</strong></span> patterns for each
filter you use. If a message matches two or more of these patterns, and
-the $spam_separator variable is set to a string, then the
+the <a class="link" href="reference.html#spam-separator" title="3.268. spam_separator">$spam_separator</a> variable is set to a string, then the
message's spam tag will consist of all the <span class="emphasis"><em>format</em></span> strings joined
-together, with the value of $spam_separator separating
+together, with the value of <a class="link" href="reference.html#spam-separator" title="3.268. spam_separator">$spam_separator</a> separating

Format strings are a general concept you'll find in several locations
-through the mutt configuration, especially in the
-<a href="reference.html#index-format" title="3.100. index_format">$index_format"</a>,
-<a href="reference.html#pager-format" title="3.139. pager_format">$pager_format"</a>,
-<a href="reference.html#status-format" title="3.278. status_format">$status_format"</a>,
-and other ``*_format'' variables. These can be very straightforward,
+through the Mutt configuration, especially in the
+<a class="link" href="reference.html#index-format" title="3.114. index_format">$index_format</a>,
+<a class="link" href="reference.html#pager-format" title="3.150. pager_format">$pager_format</a>,
+<a class="link" href="reference.html#status-format" title="3.282. status_format">$status_format</a>,
+and other related variables. These can be very straightforward,
and it's quite possible you already know how to use them.
</p><p>
The most basic format string element is a percent symbol followed
by another character. For example, <code class="literal">%s</code>
-represents a message's Subject: header in the <a href="reference.html#index-format" title="3.100. index_format">$index_format"</a> variable. The
-``expandos'' available are documented with each format variable, but
+represents a message's Subject: header in the <a class="link" href="reference.html#index-format" title="3.114. index_format">$index_format</a> variable. The
+“<span class="quote">expandos</span>” available are documented with each format variable, but
there are general modifiers available with all formatting expandos,
too. Those are our concern here.
</p><p>
-Some of the modifers are borrowed right out of C (though you might

+the <code class="literal">[-]m.n</code> modifiers, as in <code class="literal">%-12.12s</code>. As with
such programming languages, these modifiers allow you to specify the
-minumum and maximum size of the resulting string, as well as its
-justification. If the ``-'' sign follows the percent, the string will

permitted to exceed that width, no matter its natural size. Each of
these three elements is optional, so that all these are legal format

-<code class="literal">%4c</code>

+<code class="literal">%.15F</code> and <code class="literal">%-12.15L</code>.
</p><p>
Mutt adds some other modifiers to format strings. If you use an equals
symbol (<code class="literal">=</code>) as a numeric prefix (like the minus
above), it will force the string to be centered within its minimum
space range. For example, <code class="literal">%=14y</code> will reserve 14
-characters for the %y expansion -- that's the X-Label: header, in
-<code class="literal">$index_format</code>. If the expansion

results in a string less than 14 characters, it will be centered in a
-14-character space. If the X-Label for a message were "test", that
-expansion would look like `` test ''.
+14-character space. If the X-Label for a message were “<span class="quote">test</span>”, that
+expansion would look like “<span class="quote"> test </span>”.
</p><p>
There are two very little-known modifiers that affect the way that an
-expando is replaced. If there is an underline (``_'') character
+expando is replaced. If there is an underline (“<span class="quote">_</span>”) character
between any format modifiers (as above) and the expando letter, it will

+expands in all lower case. And if you use a colon (“<span class="quote">:</span>”), it will
replace all decimal points with underlines.

+Depending on the format string variable, some of its sequences can be
+used to optionally print a string if their value is nonzero. For
+example, you may only want to see the number of flagged messages if such
+messages exist, since zero is not particularly meaningful. To optionally
+print a string based upon one of the above sequences, the following
+construct is used:
+</p><pre class="screen">
+%?<sequence_char>?<optional_string>?</pre><p>
+where <span class="emphasis"><em>sequence_char</em></span> is an expando, and
+<span class="emphasis"><em>optional_string</em></span> is the string you would like printed if
+<span class="emphasis"><em>sequence_char</em></span> is nonzero.
+<span class="emphasis"><em>optional_string</em></span> may contain other
+sequences as well as normal text, but you may not nest optional
+strings.
+</p><p>
+Here is an example illustrating how to optionally print the number of
+new messages in a mailbox in
+<a class="link" href="reference.html#status-format" title="3.282. status_format">$status_format</a>:
+</p><pre class="screen">
+%?n?%n new messages.?</pre><p>
+You can also switch between two strings using the following construct:
+</p><pre class="screen">
+%?<sequence_char>?<if_string>&<else_string>?</pre><p>
+If the value of <span class="emphasis"><em>sequence_char</em></span> is
+non-zero, <span class="emphasis"><em>if_string</em></span> will be expanded,
+otherwise <span class="emphasis"><em>else_string</em></span> will be expanded.

+In most format strings, Mutt supports different types of padding using
+special %-expandos:
+</p><div class="variablelist"><dl><dt><span class="term"><code class="literal">%|X</code></span></dt><dd><p>
+When this occurs, Mutt will fill the rest of the
+line with the character <code class="literal">X</code>. For
+example, filling the rest of the line with dashes is
+done by setting:
+</p><pre class="screen">
+set status_format = "%v on %h: %B: %?n?%n&no? new messages %|-"</pre></dd><dt><span class="term">
+<code class="literal">%>X</code>
+</span></dt><dd><p>
+Since the previous expando stops at the end of line, there must be a way
+to fill the gap between two items via the <code class="literal">%>X</code>
+expando: it puts as many characters <code class="literal">X</code> in between two
+items so that the rest of the line will be right-justified. For example,
+to not put the version string and hostname the above example on the left
+but on the right and fill the gap with spaces, one might use (note the
+space after <code class="literal">%></code>):
+</p><pre class="screen">
+set status_format = "%B: %?n?%n&no? new messages %> (%v on %h)"</pre></dd><dt><span class="term"><code class="literal">%*X</code>
+</span></dt><dd><p>
+Normal right-justification will print everything to the left of the
+<code class="literal">%></code>, displaying padding and whatever lies to the
+right only if there's room. By contrast, “<span class="quote">soft-fill</span>” gives
+priority to the right-hand side, guaranteeing space to display it and
+showing padding only if there's still room. If necessary, soft-fill will
+eat text leftwards to make room for rightward text. For example, to
+right-justify the subject making sure as much as possible of it fits on
+screen, one might use (note two spaces after <code class="literal">%*
+</code>: the second ensures there's a space between the truncated
+right-hand side and the subject):
+</p><pre class="screen">
+set index_format="%4C %Z %{%b %d} %-15.15L (%?l?%4l&%4c?)%* %s"</pre></dd></dl></div></div></div></div><div class="navfooter"><hr /><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="gettingstarted.html">Prev</a> </td><td width="20%" align="center"> </td><td width="40%" align="right"> <a accesskey="n" href="advancedusage.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">Chapter 2.
