On OpenBSD 6.5, the prompt is repeated, but not the actual command line... Don't try to cope with that. Reported by Bruno Haible. https://lists.gnu.org/r/bug-bison/2020-05/msg00015.html * examples/c/bistromathic/bistromathic.test: Skip when readline behave this way.
bistromathic - all the bells and whistles
This example demonstrates best practices when using Bison.
- Its hand-written scanner tracks locations.
- Its interface is pure.
- It uses the
errortoken to get error recovery. - Its interface is "incremental", well suited for interaction: it uses the push-parser API to feed the parser with the incoming tokens.
- It features an interactive command line with completion based on the
parser state, based on
yyexpected_tokens. - It uses Bison's standard catalogue for internationalization of generated messages.
- It uses a custom syntax error with location, lookahead correction and token internationalization.
- It supports debug traces with semantic values.
- It uses named references instead of the traditional $1, $2, etc.
