Option 1 is incompatible with the documentation + ("After `yypush_parse` returns a status other than `YYPUSH_MORE`, the + parser instance `yyps` may be reused for a new parse."). + + So Option 2 wins, reusing the private `yynew` member to record that a + parse was finished, and therefore that the state must reset in the + next call to `yypull_parse`. + + While at it, this implementation now reuses the previously enlarged + stacks from one parse to another. + + * data/skeletons/yacc.c (yypstate_new): Set up the stacks in their + initial configurations (setting their bottom to the stack array), and + use yypstate_clear to reset them (moving their top to their bottom). + (yypstate_delete): Adjust. + (yypush_parse): At the beginning, clear yypstate if needed, and at the + end, record when yypstate needs to be clearer. + + * examples/c/bistromathic/parse.y (expected_tokens): Do not propose + autocompletion when there are parse errors. + * examples/c/bistromathic/bistromathic.test: Check that case. + +2020-06-29 Akim Demaille + + bistromathic: don't display undefined locations + Currently, completion when there is a syntax error shows broken + locations. + + * examples/c/bistromathic/parse.y (expected_tokens): Initialize the + location. + * examples/c/bistromathic/bistromathic.test: Check that. + +2020-06-29 Akim Demaille + + yacc.c: simplify initialization of push parsers + The previous commit ("yacc.c: declare and initialize and the same + time") made b4_initialize_parser_state_variables useless. + + * data/skeletons/yacc.c (b4_initialize_parser_state_variables): Inline + into... + (yypstate_clear): here. + +2020-06-29 Akim Demaille + + regen + +2020-06-29 Akim Demaille + + yacc.c: declare and initialize and the same time + In order to factor the code of push and pull parsers, the declaration + of the parser's state variable was common (being local variable in + pull parsers, and struct members in push parsers).

That's because an error message that reports a + bazillion of possible tokens is useless. + + In that case yyexpected_tokens returned 0, so the user would not know + if there are too many expected tokens or none (yes, that's possible). + + There are several ways to tell the user in which situation she's in: + + - return some E2MANY, a negative value. Then it makes the pattern + + int argsize = yypcontext_expected_tokens (ctx, arg, ARGS_MAX); + if (argsize < 0) + return argsize; + + no longer valid, as for E2MANY (i) the user must generate the error + message anyway, and (ii) she should not return E2MANY + + - return ARGS_MAX + 1. Then it makes it dangerous for the user, as + she has to iterate update `min (ARGS_MAX, argsize)`. + + Returning 0 is definitely simpler and safer for the user, as it tells + her "this is not an error, just generate your message without a list + of expecting tokens".
