What is the equivalent of <<EOF>> in jison when using JSON format

Question

I'm reading through the jison documentation and one of the examples gives a lexer rule that matches the end of file (<<EOF>>). However, that can only be used if you are writing the grammar in JISON format. Instead, I am using the JSON format to describe my grammar, but I cannot find anything in the documentation describing how to match the end of file. I have tried using "<<EOF>>" as the lexer rule, but that literally matches the string <<EOF>>.

How do I do this? Is there more documentation for jison somewhere that I'm missing?

Answer 1

After digging into the source code for lex-parser, it looks like $ does what I want. Instead of matching the end of a line, it matches the end of a file. <<EOF>> actually gets converted to $ when parsing the lex section of a jison file.
