How to use EOI ?

[mingodad]

In several grammars they refer to EOI in the lexer, something like:

<xq,xe,xus><<EOF>>		{ yyerror("unterminated quoted string"); }
...
<xb><<EOF>>		{ yyerror("unterminated bit string literal"); }
...
<*><<EOF>>                              return 'EOF';
...
<<EOF>>			{ SET_YYLLOC(); yyterminate();	}

How to use/access the EOI through a grammar ?

I once added <<EOF>> support, but it didn't work well. Harmut suggested removing it as 'nobody needs that feature' or some-such.

Let me think about it again with the benefit of greater experience.

Can you point it out in git history ?

This pre-github. The first proper release was in 2006 (I think it was on CodeProject originally) and it was committed to github in August 2012.
