SWI-Prolog can be executed in one of the following modes:
swipl[option ...] script-file [arg ...]
#!/path/to/executable[option ...] is executed. Arguments after the script file are made available in the Prolog flag argv.
swipl[option ...] prolog-file ... [[
--] arg ...]
.prologor (on Windows) the user preferred extension registered during installation), these files are loaded. The first file is registered in the Prolog flag associated_file. In addition, pl-win[.exe] switches to the directory in which this primary source file is located using working_directory/2.
swipl-o output -c prolog-file ...
swipl-o output -b bootfile prolog-file ...
eval `swipl --dump-runtime-variables` cc -I$PLBASE/include -L$PLBASE/lib/$PLARCH ...
The option can be followed by
=sh to dump in POSIX shell
format (default) or
=cmd to dump in MS-Windows cmd.exe

--no-name (false). They
are written as
--no-name below as the default is `true'.

--no-pcemakes it unavailable in the session.
http://localhost:port. If port is specified, the server is started at the given port and the browser is not launched.

init.pl`-f none' stops SWI-Prolog from searching for a startup file. This option can be used as an alternative to -s file that stops Prolog from loading the personal initialisation file. See also section 2.2.
<script>.rc. The default script name is deduced from the executable, taking the leading alphanumerical characters (letters, digits and underscore) from the program name. -F none stops looking for a script. Intended for simple management of slightly different versions. One could, for example, write a script
iso.rcand then select ISO compatibility mode using
pl -F isoor make a link from iso-pl to pl.
. On other systems it is
. A value is either a term of the form alias(value) or pathname. The computed aliases are added to file_search_path/2 using asserta/1, so they precede predefined values for the alias. See file_search_path/2 for details on using this file location mechanism.
As of version 7.7.14 the stacks are no longer limited individually. Instead, only the combined size is limited. Note that 32 bit systems still pose a 128Mb limit. See section 2.21.1. The combined limit is by deault 1Gb on 64 bit machines and 512Mb on 32 bit machines.
For example, to limit the stacks to 32Gb use the command below. Note
that the stack limits apply per thread. Individual threads may
be controlled using the
stack_limit(+Bytes) option of
thread_create. Any thread can call
adjust the stack limit. This limit is inherited by threads created from
$ swipl --stack_limit=32g
% swipl <options> -g go -g halt
