Description copied from interface: CommandHandler

Called when a CommandToken is being handled by the DOMBuilder.

Specified by:

handleCommand in interface CommandHandler

Parameters:

builder - DOMBuilder running this process, which provides access to convenience method for appending Nodes to the DOM

parentElement - parent Element that the resulting Nodes should (can) be added to

token - Token representing the command being processed.

Throws:

SnuggleParseException - to indicate a client error

handleCommandMathMode

public void handleCommandMathMode(DOMBuilder builder,
                                  Element parentElement,
                                  CommandToken token)
                           throws SnuggleParseException

Handles accents in MATH mode.

Parameters:

builder -

parentElement -

token -

Throws:

DOMException

SnuggleParseException

handleCommandTextMode

public void handleCommandTextMode(DOMBuilder builder,
                                  Element parentElement,
                                  CommandToken token)
                           throws SnuggleParseException

LaTeX only adds an accent to the first character of the first token, and only if it is text. If not, it outputs a lone accent character before the first token.

For simplicity, we will only allow a single simple text token as the argument of this command since anything else is really a nasty hack and does nothing for the output in LaTeX.

Throws:

SnuggleParseException
