Detailed Description

These are the possible values that can be or'ed together to set Program parse options

Variable Documentation

const Qore::PO_ALLOW_BARE_REFS = PO_ALLOW_BARE_REFS

Prohibits the use of the '$' character in variable names, method calls, and object member references.

This option should probably be named "PO_REQUIRE_BARE_REFS" as it is an error to use the "$" character when this option is set

See also

%allow-bare-refs

const Qore::PO_ASSUME_LOCAL = PO_ASSUME_LOCAL

Assume local variable scope when variables are first referenced if no my or our is present.

This option is set implicitly with PO_NEW_STYLE

%assume-local

const Qore::PO_FREE_OPTIONS = PO_FREE_OPTIONS

mask of options that have no effect on code access or code safety but just affect programming style

made up of PO_ALLOW_BARE_REFS | PO_ASSUME_LOCAL

const Qore::PO_IN_MODULE = PO_IN_MODULE

Only set by the system when in a user module Program.

Note

This option cannot be set manually or an exception will be raised

const Qore::PO_LOCK_WARNINGS = PO_LOCK_WARNINGS

Disallows changes to the warning mask.
