json: Leave rejecting invalid interpolation to parser
Both lexer and parser reject invalid interpolation specifications. The parser's check is useless. The lexer ends the token right after the first bad character. This tends to lead to suboptimal error reporting. For instance, input [ %04d ] produces the tokens JSON_LSQUARE [ JSON_ERROR %0 JSON_INTEGER 4 JSON_KEYWORD d JSON_RSQUARE ] The parser then yields an error, an object and two more errors: error: Invalid JSON syntax object: 4 error: JSON parse error, invalid keyword error: JSON parse error, expecting value Dumb down the lexer to accept [A-Za-z0-9]*. The parser's check is now used. Emit a proper error there. The lexer now produces JSON_LSQUARE [ JSON_INTERP %04d JSON_RSQUARE ] and the parser reports just JSON parse error, invalid interpolation '%04d' Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-Id: <20180823164025.12553-41-armbru@redhat.com>
