Qore Programming Language Reference Manual  0.8.11.1
qore Executable Command-Line Processing

This section describes command-line processing for the qore binary; see Qore::GetOpt for the class allowing for command-line processing in Qore code

Qore will scan the command-line for the options in the following table. Arguments after the script name will be passed to the script in the global $ARGV variable as a list of options. $ARGV[0] will be the first option and will not be the script name. If no script name is given and the –exec option is not used, then Qore code is read from standard input. The $QORE_ARGV variable will have the original Qore command-line in it, however

Usage: qore [options] [script_file_name]

Parse Option Command-Line Parameters

Long Param Short Description
--define=arg -D Creates and optionally sets a value for a parse define
--load=arg -l Loads a module immediately. The argument can be a module/feature name or an absolute path to the module
--no-global-vars -G Disallows the use of global variables. Equivalent to parse option Qore::PO_NO_GLOBAL_VARS and the %no-global-vars directive
--no-subroutine-defs -S Disallows subroutine (function) definitions. Equivalent to parse option Qore::PO_NO_SUBROUTINE_DEFS and the %no-subroutine-defs directive
--no-thread-control -R Disallows any thread control operations (background operator and thread_exit statement, for example). Equivalent to parse option Qore::PO_NO_THREAD_CONTROL and the %no-thread-control directive
--no-thread-classes n/a Disallows access to thread classes (for example, the Mutex class, Gate class, Queue class, etc). Equivalent to parse option Qore::PO_NO_THREAD_CLASSES and the %no-thread-classes directive
--no-threads -T Disallows access to both thread control and thread classes (equivalent to the –no-thread-control and –no-thread-classes options documented above). Equivalent to parse option Qore::PO_NO_THREADS and the %no-threads directive
--no-top-level -L Disallows top level code. Equivalent to parse option Qore::PO_NO_TOP_LEVEL_STATEMENTS and the %no-top-level directive
--no-class-defs n/a Disallows class definitions. Equivalent to Qore::PO_NO_CLASS_DEFS and the %no-class-defs directive
--no-namespace-defs n/a Disallows new namespace definitions. Equivalent to Qore::PO_NO_NAMESPACE_DEFS and the %no-namespace-defs directive
--no-external-process -E Disallows any access to external processes (with system(), backquote(), exec(), the backquote operator, etc). Equivalent to parse option Qore::PO_NO_EXTERNAL_PROCESS and the %no-external-process directive
--no-process-control -P Disallows access to functions that would affect the current process (exit(), fork(), etc). Equivalent to parse option Qore::PO_NO_PROCESS_CONTROL and the %no-process-control directive
--no-filesystem -F Disallows access to the local filesystem; puts the %no-filesystem parse option in effect. Equivalent to parse option code Qore::PO_NO_FILESYSTEM and the %no-filesystem parse directive
--no-constant-defs n/a Disallows constant definitions. Equivalent to parse option Qore::PO_NO_CONSTANT_DEFS and the %no-constant-defs directive
--no-network -Y Disallows access to the network; puts the %no-network parse option in effect. Equivalent to parse option code Qore::PO_NO_NETWORK and the %no-network parse directive
--no-new -N Disallows use of the new operator. Equivalent to parse option Qore::PO_NO_NEW and the %no-new directive
--no-database -D Disallows use of database functionality. Equivalent to parse option Qore::PO_NO_DATABASE and the %no-database directive
--no-child-restrictions -I Allows child program objects to have parse option restrictions that are not a strict subset of the parents. Equivalent to parse option Qore::PO_NO_CHILD_PO_RESTRICTIONS and the %no-child-restrictions directive
--require-our -O Requires global variables to be declared with our prior to use (similar to perl's use strict vars pragma). Equivalent to parse option Qore::PO_REQUIRE_OUR and the %require-our directive
--lock-options -K Prohibits further changes to parse options (equivalent to the %lock-options directive)
--lock-warnings -A Prohibits further changes to the warning mask. Equivalent to parse option Qore::PO_LOCK_WARNINGS and the %lock-warnings directive
--enable-all-warnings -W Enables all warnings. Equivalent to the %enable-all-warnings directive
--enable-warning=arg -w Enables the named warning. Equivalent to the %enable-warning directive
--list-warnings -i Lists all valid warnings in Qore and exits immediately

Miscellaneous Command-Line Parameters

Long Param Short Description
--exec=arg -e parses and executes the argument text as a Qore program. If this option is specified then any script given on the command-line will be ignored
--exec-class[=arg] -x instantiates the class with the same name as the program (with the directory path and extension stripped); also turns on –no-top-level. If the program is read from stdin or from the command line, an argument must be given specifying the class name
--show-module-errors -m Shows any errors loading Qore modules
--charset=arg -c Sets the default character encoding for the program
--show-charset=arg -s Shows a list of all known character encodings
--show-aliases -a Shows a list of all known character encoding aliases
--help -h Shows help text
--version -v Shows Qore library version information and exits

There are two additional options available with debugging versions of Qore as follows:

Description of Debugging Command-Line Parameters

Long Param Short Description
--debug=arg -d Turns on Qore debugging output (output to stderr). Higher arg numbers give more output. This option is only available with DEBUG builds
--trace -t Turns on Qore tracing (output to stderr). This option is only available with DEBUG builds
