Calling Sequence

EnableParseRule(rule)

DisableParseRule(rule)

QueryParseRule(rule)

Parameters

rule

-

rule name (string) or set or list of rule names

Description

• 

The EnableParseRule command turns on the specified parse rule(s) in the Typesetting package for use in 2-D input, while the DisableParseRule command turns off the specified parse rule(s) in the Typesetting package for use in 2-D input. The QueryParseRule command shows whether a rule is enabled or not. It returns a set of elements a=b where a is a rule name and b is true if a is enabled and false otherwise.

• 

There are too many rules to be able to list them all here, but all are available in the Rules area of the interactive Typesetting Assistant.

• 

As a simple example, the rule BesselJ corresponds to the capability of parsing the function J with a symbolic subscript (say v) as a function a single variable (say x) as the BesselJ function (BesselJv,x).

Compatibility

• 

The Typesetting[QueryParseRule] command was introduced in Maple 2017.
