Re: YYRECOVERING() in yylex function

Hi Nathanael,Unfortunately the project is quite big but I want to make a mi=
nimal reproducible example for it. Before doing so though, I'd like to unde=
rstand if it makes sense at all to use YYRECOVERING() in yylex. I have a ru=
le for each token a validating action which triggers YYERROR if the token i=
s invalid. The issue I noticed is that e.g. for the input A B C where token=
 B is invalid, YYERROR is triggered after which yylex is called by bison. T=
hus yylex processes the input and returns the next token (C). Then the acti=
on set up for error recovery takes place which checks if it's already the e=
nd of input. The end of input check returns true since token C has been ret=
urned by yylex in which case I raise YYABORT. That's why I thought, if I co=
uld check in yylex that YYRECOVERING() is 1 then it could return the previo=
us token not the next. However, as I reported, I get a compile time error s=
ince YYRECOVERING() may have been designed to be used only in actions. I ho=
pe I could sum up clearly what I'm doing. Nevertheless, I'll try to make a =
minimal example.Best regards,r0ller-------- Eredeti lev=C3=A9l --------Fela=
