# 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 `error` token 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.
|
|
|
|
To customize the interaction with bistromathic, see the GNU Readline user
|
|
manual (see `info rluserman`).
