The BNF Converter
What is the BNF Converter?
The BNF Converter (bnfc) is a compiler construction tool generating a compiler front-end from a Labelled BNF grammar. It is currently able to generate C, C++, C#, Haskell, Java, and OCaml, as well as XML representations.
Given a Labelled BNF grammar the tool produces:
- an abstract syntax implementation
- a case skeleton for the abstract syntax in the same language
- an Alex, Ocamllex, JLex, or Flex lexer generator file
- a Happy, Ocamlyacc, Menhir, ANTLR, CUP, or Bison parser generator file
- a pretty-printer as a Haskell/Ocaml/Java/C++/C module
- a Latex file containing a readable specification of the language

Everything needed to build bnfc is available in the haskell platform.
On Debian, you can install the dependencies as follows
sudo apt-get install haskell-platform
yum install haskell-platform
Then proceed with the installation.
Some binaries are available at https://github.com/BNFC/bnfc/releases .
To install bnfc from hackage.haskell.org:
cabal install BNFC
To install the development version of bnfc:
git clone https://github.com/BNFC/bnfc.git cd bnfc/source cabal install
Here is how to build and run the different test suites for bnfc.
cabal sandbox init # Cabal >= 1.18 only cabal install --only-dependencies --enable-tests cabal configure --enable-tests cabal build cabal test
