This directory contains examples of Bison grammar files.
|
|
|
|
Most of them come from the documentation, which should be installed together
|
|
with Bison. The URLs are provided for convenience.

* Examples in C
|
|
|
|
** rpcalc - Reverse Polish Notation Calculator
|
|
The first example is that of a simple double-precision Reverse Polish
|
|
Notation calculator (a calculator using postfix operators). This example
|
|
provides a good starting point, since operator precedence is not an issue.
|
|
|
|

|
|
https://www.gnu.org/software/bison/manual/html_node/RPN-Calc.html
|
|
|
|
** mfcalc - Multi-Function Calculator
|
|
A more complete C example: a multi-function calculator.
|
|
|
|
Extracted from the documentation: "Multi-Function Calculator: mfcalc".
|
|
https://www.gnu.org/software/bison/manual/html_node/Multi_002dfunction-Calc.html
|
|
|
|
|
|
|
|
* Examples in C++
|
|
|
|
** variant.yy - Self-contained example in C++
|
|
A simple C++ example in a single file, 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 type and
|
|
effective semantic value.
|
|
|
|
** variant-11.yy - Self-contained example in modern C++
|
|
Another simple C++ example, closely related to the previous one, but
|
|
exhibiting support for C++11's move semantics.
|
|
|
|
** calc++ - A Complete C++ Example
|
|
A fully featured C++ version of the canonical example for parsers: a
|
|
calculator. Also uses Flex for the scanner.
|
|
|
|
Extracted from the documentation: "A Complete C++ Example".
