LaTeXML::Parameters(3pm)

Parameters Methods

"$parameters = parseParameters($prototype,$for);"

Parses a string for a sequence of parameter specifications. Each specification should be of the form

 {}     reads a regular TeX argument, a sequence of
        tokens delimited by braces, or a single token.
 {spec} reads a regular TeX argument, then reparses it
        to match the given spec. The spec is parsed
        recursively, but usually should correspond to
        a single argument.
 [spec] reads an LaTeX-style optional argument. If the
        spec is of the form Default:stuff, then stuff
        would be the default value.
 Type   Reads an argument of the given type, where either
        Type has been declared, or there exists a ReadType
        function accessible from LaTeXML::Package::Pool.
 Type:value, or Type:value1:value2...    These forms
        pass additional Tokens to the reader function.
 OptionalType  Similar to Type, but it is not considered
        an error if the reader returns undef.
 SkipType  Similar to OptionalType, but the value returned
        from the reader is ignored, and does not occupy a
        position in the arguments list.

"@parameters = $parameters->getParameters;"

Return the list of "LaTeXML::Parameter" contained in $parameters.

"@tokens = $parameters->revertArguments(@args);"

Return a list of LaTeXML::Token that would represent the arguments such that they can be parsed by the Gullet.

"@args = $parameters->readArguments($gullet,$fordefn);"

Read the arguments according to this $parameters from the $gullet. This takes into account any special forms of arguments, such as optional, delimited, etc.

"@args = $parameters->readArgumentsAndDigest($stomach,$fordefn);"

Reads and digests the arguments according to this $parameters, in sequence. this method is used by Constructors.
