Use --html to generate *.html directly.
No longer demonstrate --xml.
No longer show rules for xml to html.
Use --header, not --defines.
Use --graph without specifying the output file now that we
generate *.gv by default.

Examples in C++

This directory contains examples of Bison grammar files in C++.

You can run make to compile these examples. And make clean to tidy afterwards.

simple.yy - Simple example in C++14

A very simple example in C++, based on variants and symbol constructors. Variants allow to use any C++ type as semantic value type, and symbol constructors ensure consistency between declared token kind and effective semantic value.

Run as ./simple.

Extracted from the documentation: A Simple C++ Example.

variant.yy - Self-contained example in C++98

A variation of simple.yy, in C++98.

Run as ./variant.

variant-11.yy - Self-contained example in modern C++

Another variation of simple.yy, closely related to the previous one, but exhibiting support for C++11's move semantics.

Run as ./variant or ./variant NUMBER.

calc++ - A Complete C++ Example

A fully featured C++ version of the canonical example for parsers: a calculator. Also uses Flex for the scanner.

Don't look at this example first: it is fully featured and can serve as a starting point for a clean parser in C++. The previous examples are better introductory examples, and the C examples are also useful introductory examples.
