  -h, --help                    Print usage message

DESCRIPTION ^

sa-compile uses re2c to compile the site-wide parts of the SpamAssassin ruleset. No part of user_prefs or any files included from user_prefs can be built into the compiled set.

This compiled set is then used by the Mail::SpamAssassin::Plugin::Rule2XSBody plugin to speed up SpamAssassin's operation, where possible, and when that plugin is loaded.

re2c can match strings much faster than perl code, by constructing a DFA to match many simple strings in parallel, and compiling that to native object code. Not all SpamAssassin rules are amenable to this conversion, however.

This requires re2c (see http://re2c.org/), and the C compiler used to build Perl XS modules, be installed.

Note that running this, and creating a compiled ruleset, will have no effect on SpamAssassin scanning speeds unless you also edit your v320.pre file and ensure this line is uncommented:

  loadplugin Mail::SpamAssassin::Plugin::Rule2XSBody

Additionally, "sa-compile" will not restart "spamd" or otherwise cause a scanner to reload the now-compiled ruleset automatically.

OPTIONS ^

--list

Output the extracted base strings to STDOUT, instead of generating the C extension code.

--sudo

Use sudo(8) to run code as 'root' when writing files to the compiled-rules storage area (which is @@LOCAL_STATE_DIR@@/compiled/@@PERL_MAJOR_VER@@/@@VERSION@@ by default).

--quiet

Produce less diagnostic output. Errors will still be displayed.

--keep-tmps

Keep temporary files after the script completes, instead of deleting them.

-C path, --configpath=path, --config-file=path

Use the specified path for locating the distributed configuration files. Ignore the default directories (usually /usr/share/spamassassin or similar).

--siteconfigpath=path

Use the specified path for locating site-specific configuration files. Ignore the default directories (usually /etc/mail/spamassassin or similar).

--updatedir

By default, sa-compile will use the system-wide rules update directory:

        @@LOCAL_STATE_DIR@@/compiled/@@PERL_MAJOR_VER@@/@@VERSION@@

If the updates should be stored in another location, specify it here.

Note that use of this option is not recommended; if sa-compile is placing the compiled rules the wrong directory, you probably need to rebuild SpamAssassin with different Makefile.PL arguments, instead of overriding sa-compile's runtime behaviour.

--cf='config line'

Add additional lines of configuration directly from the command-line, parsed after the configuration files are read. Multiple --cf arguments can be used, and each will be considered a separate line of configuration.

-p prefs, --prefspath=prefs, --prefs-file=prefs

Read user score preferences from prefs (usually $HOME/.spamassassin/user_prefs) .

-D [area,...], --debug [area,...]

Produce debugging output. If no areas are listed, all debugging information is printed. Diagnostic output can also be enabled for each area individually; area is the area of the code to instrument.

For more information about which areas (also known as channels) are available, please see the documentation at http://wiki.apache.org/spamassassin/DebugChannels.

-h, --help

Print help message and exit.

-V, --version

Print sa-compile version and exit.
