Re: [Csnd-dev] [EXTERNAL] [Csnd-dev] Syntax error with :

Do you remember what version used to work?
This I think is a lexer error, picked up here

{IDENT}:/[ \t\n]  { char *pp = yytext;
                  while (*pp==' ' || *pp=='\t') pp++;
                  *lvalp = make_label(csound, pp); return LABEL_TOKEN;
                }

so it looks like it was there from the beginning of the new parser.

Not sure how it could be disambiguated as anything forming that pattern is read as a label.
I guess that rule would have to be changed not to make a label but something that could later be disambiguated in the parser.

This line gives an error:

k2 = k0 > 0 ? k0: -1

error: syntax error, unexpected LABEL_TOKEN  (token "k0:") from file xxx.csd (1)

It is ok if the ":" has a space before the variable

k2 = k0 > 0 ? k0 : -1

The code used to work some months ago, so this might be a recent change. I guess it should not be difficult to disambiguate the parsing, since a label should start a line.

Thanks,
