When the user ctrl-d the line, we left the cursor not at col 0. Let's fix that. This revealed a few short-comings in the testing framework. * examples/test (run): Also display the diffs. And support -n. * examples/c/bistromathic/bistromathic.test * examples/c/bistromathic/parse.y
bistromathic - all the bells and whistles
This example demonstrates best practices when using Bison.
- Its hand-written scanner tracks locations.
- Its interface is pure.
- 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.
