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 https://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- /var/lib/spamassassin/compiled/5.042/4.000002by 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/spamassassinor similar).
- --siteconfigpath=path
- Use the specified path for locating site-specific configuration files. Ignore the default directories (usually - /etc/mail/spamassassinor similar).
- --updatedir
- By default, - sa-compilewill use the system-wide rules update directory:- /var/lib/spamassassin/compiled/5.042/4.000002 - 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.PLarguments, 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 <https://wiki.apache.org/spamassassin/DebugChannels>. 
- -h, --help
- Print help message and exit. 
- -V, --version
- Print sa-compile version and exit.
