.SH "DESCRIPTION"
.sp
\fBport search\fR helps you find ports by partial matches of the name or description (or other fields, depending on the given options)\&. It is the tool of choice if you are looking for software in MacPorts\&.
.sp
\fBsearch\fR works by searching for your given keyword(s) in a set of fields of all available ports\&. By default, a port\(cqs name and short description are searched, as if you had specified both \fB\-\-name\fR and \fB\-\-description\fR\&. See \fBOPTIONS\fR for possible values for \fIfield\fR\&.
.sp
Note that you can specify multiple fields to be searched\&. A port will be printed when any of the fields matches your keyword(s)\&. If you specify multiple keywords, \fBsearch\fR will run multiple separate searches, one for each given keyword\&.
.SH "OPTIONS"
.SS "Search behavior"
.PP
\fB\-\-case\-sensitive\fR
.RS 4
Do not ignore case when searching for the given keyword\&.
.RE
.PP
\fB\-\-exact\fR
.RS 4
Search for the given string exactly\&. Disables
\fB\-\-glob\fR
(the default) and
\fB\-\-regex\fR\&.
.RE
.PP
\fB\-\-glob\fR
.RS 4
Treat the keyword(s) as wildcard (i\&.e\&., expand
\fI*\fR,
\fI?\fR
and
\fI[sets]\fR)\&. This is the default\&. See the
\fBstring match\fR
section of
\fBstring\fR(n)
for a detailed syntax description\&.
.RE
.PP
\fB\-\-regex\fR
.RS 4
Treat the given string as a Tcl regular expression\&. See
\fBre_syntax\fR(n)
for a description of Tcl regular expressions\&.
.RE
.SS "Output behavior"
.PP
\fB\-\-line\fR
.RS 4
Print one match per line, where a line consists of name, version, categories and short description\&.
.RE
.sp
See also \fB\-q\fR in the \fBGLOBAL OPTIONS\fR section below\&.
.SS "Field selection"
.PP
\fB\-\-category\fR, \fB\-\-categories\fR
.RS 4
Search the category\&. You can use this to list all ports in a given category\&. For example,
\fBport search \-\-category haskell\fR
will print all Haskell ports in MacPorts\&. If you don\(cqt need the description it\(cqs usually faster to use the pseudo\-portname selector
\fBcategory:haskell\fR
with
\fBport-echo\fR(1)
(i\&.e\&.,
\fBport echo category:haskell\fR) instead\&. See
\fBport\fR(1)
for more information on pseudo\-port selectors\&.

\fB\-\-depends\fR, \fB\-\-depends_build\fR, \fB\-\-depends_extract\fR, \fB\-\-depends_fetch\fR, \fB\-\-depends_lib\fR, \fB\-\-depends_run\fR
.RS 4
Search for ports that depend on the port given as keyword\&.
\fB\-\-depends\fR
is an alias for all other
\fB\-\-depends_\fR
options combined\&. Note that only dependencies present in default variants will be found by this search\&. As with
\fB\-\-category\fR, there also are pseudo\-portname selectors available for dependencies\&.
.RE
.PP
\fB\-\-description\fR, \fB\-\-long_description\fR
.RS 4
Test the search string against ports\*(Aq descriptions\&.
.RE
.PP
\fB\-\-homepage\fR
.RS 4
Search for the keyword(s) in the homepage property\&.
.RE
.PP
\fB\-\-maintainer\fR
.RS 4
Search for ports maintained by a specific maintainer\&. Note that there also is a pseudo\-portname selector available for maintainer addresses\&. See
\fBport\fR(1)
for more information\&.
.RE
.PP
\fB\-\-name\fR
.RS 4
Search in ports\*(Aq names\&. Since this is the default (together with
\fB\-\-description\fR), this flag is only useful when you to search
\fIonly\fR
in the name, but not the description\&.
.RE
.PP
\fB\-\-portdir\fR
.RS 4
Test the search string against the path of the directory that contains the port\&.
.RE
.PP
\fB\-\-variant\fR, \fB\-\-variants\fR
.RS 4
Search for variant names\&.
.RE
.SH "GLOBAL OPTIONS"
.sp
Please see the section \fBGLOBAL OPTIONS\fR in the \fBport\fR(1) man page for a description of global port options\&.
.PP
\fB\-q\fR
.RS 4
Only print the name of the port that matched your query\&. Print one match per line\&.
.RE
.SH "EFFICIENT SEARCHING"
.sp
The output of \fBsearch\fR can be overwhelming and confusing, especially with a large number of results\&. Here are a few tips to improve your search efficiency with MacPorts\&.
.sp
Suppose you are looking for PHP in MacPorts\&. You might start with
.sp
.if n \{\
.RS 4
.\}
.nf
$> port search php
.fi
.if n \{\
.RE
.\}
.sp
and notice your query produces a lot of output\&. In fact, at the time of writing this, this search produces 763 matches\&. By default, \fBsearch\fR searches both name and description of a port\&. While we\(cqre looking for PHP, we can reduce the number of hits by using the \fB\-\-name\fR flag\&. Furthermore, we only want ports whose name starts with \(lqphp\(rq, so we add the \fB\-\-glob\fR flag (actually, we could leave it out because it is the default) and modify the search term to \fBphp\fR*\&. Note that the asterisk needs to be escaped or quoted to prevent the shell from interpreting it:
.sp
.if n \{\
.RS 4
.\}
.nf
$> port search \-\-name \-\-glob \*(Aqphp*\*(Aq
.fi
.if n \{\
.RE
.\}
.sp
Since that still produces 689 results, we can activate compressed output using the \fB\-\-line\fR flag
.sp
.if n \{\
.RS 4
.\}
.nf
$> port search \-\-line \-\-name \-\-glob \*(Aqphp*\*(Aq
.fi
.if n \{\
.RE
.\}
.sp
Scrolling over the output, we see a large number of PHP modules starting with php<version>\-<modulename>\&. That tells us the main PHP ports might be named php<version>\&. Using regex we can further narrow down the results:
.sp
.if n \{\
.RS 4
.\}
.nf
$> port search \-\-line \-\-name \-\-regex \*(Aq^php\ed+$\*(Aq
.fi
.if n \{\
.RE
.\}
.sp
Note it is not always necessary to drill down to reduce the amount of output\&. For example, if you\(cqre looking for \fBrrdtool\fR, a popular system to store and graph time\-series data, the simple approach works well, with only 12 ports being returned:
.sp
.if n \{\
.RS 4
.\}
.nf
$> port search rrd
.fi
.if n \{\
.RE
.\}
