Requirements

Ocaml version >= 4.13.1, modules fmt,str and linenoise ( REPL )

opam install fmt str linenoise

Installation

Pre-compiled binaries

Automatic download of the linux x86_64 binaries

curl https://raw.githubusercontent.com/coco33920/ocaml-baguettesharp-interpreter/master/download.sh | sh

the script downloads the latest binaries (which was tagged on the releases), install it as ~/.local/bin/baguette_sharp and flag it as executable. You can also do

wget https://raw.githubusercontent.com/coco33920/ocaml-baguettesharp-interpreter/master/download.sh
sh download.sh

Or just executing the script itself

wget https://github.com/coco33920/ocaml-baguettesharp-interpreter/releases/latest/download/baguette.linux64
mv baguette.linux64 ~/.local/bin/baguette_sharp
chmod +x ~/.local/bin/baguette_sharp

OPAM

Build the latest stable version in OPAM repositories opam install baguette_sharp it compile and install the latest baguette_sharp version under baguette_sharp.repl in OPAM files (which are in $PATH)

Source

You must install the dependencies to build from sources, which are fmt and linenoise. And an OCaml version of at least 4.13.1. An automatic script to download sources, install dependencies and build from source is available here :

curl https://raw.githubusercontent.com/coco33920/ocaml-baguettesharp-interpreter/master/automatic.sh | sh

Which is exactly :

opam install -y linenoise fmt
git clone https://github.com/coco33920/ocaml-baguettesharp-interpreter
cd ocaml-baguettesharp-interpreter
dune build @install
dune install

The script, same as OPAM, install the repl under baguette_sharp.repl in the OPAM files.

History

I restarted this project early 2022, to act as a TIPE (a french weird oral exam for the concours of Écoles d’Ingénieurs) to frame the formal language theory, and to do that you’ll play with our world famous pastries !

The lexer, parser and interpreter are finished, they take a string of language and transform it into an abstract syntax tree (AST) that the interpreter take to execute the language. I now work on the theoritical part of the issue (turing-completeness), and the compiler.

The syntax is really close to a BASIC but with less explicit words and keywords you’ll see :)

Support

The language supports integers, floating point numbers, strings, booleans, predicates, gotos, conditionnals gotos (if/else), and implements many of the standard instructions you can find in a language standard library. Keywords are simple and are the only instances when you don’t need parenthesis, go see the WIKI for more accurate informations

Building

dune build .

Usage

dune exec baguette_sharp_interpreter

Test

dune runtest
