Class TheLinearCLanguage

Define the character categories used by the language.

This method first calls the inherited routine, then sets up the following character categories:

• CHARCAT_SPECIAL is set to lccsSpecial

• CHARCAT_DIGIT is set to the combined values of plcsTypicalDigit and lccsDigit

The other character categories are left as they have been assigned by the inherited routine.

Define the opcodes used by the language.

This method calls AnOpcodeDictionary.bindSeveral to bind the values of lcTokenStrings to lcOpcodes. Among other things, this action causes:

• the value of clopParameterNameDelimiter to be assigned to lcdlBeginLongOption

• the value of clopParameterAbbreviationDelimiter to be assigned to lcdlBeginShortOption

• the value of clopAssignmentOperator to be assigned to lcopAssign

This ensures that the values used to describe the operation of command-line parameters to the user actually perform as described.

Define the rules used by the language.

This method calls the inherited routine first, then adds a few rules pertinent to the language:

• RULE_BEGIN_EXPRESSION, which defines the tokens that may begin an expression (tokens encountered after the assignment operator)

• RULE_END_EXPRESSION, which defines the tokens that may end an expression

• RULE_TRUTH, which defines those tokens that may represent a value of True when setting switch options

• RULE_FALSEHOOD, which defines those tokens that may represent a value of False when setting switch options

The method also establishes tokens for the rules defined by the inherited routine:

• RULE_BEGIN_STATEMENT, which defines the tokens that may begin a statement (a single command-line parameter)

• RULE_END_STATEMENT, which defines the tokens that may end a statement
