An expression based scripting language

bread 🍞

bread is an expression based, object oriented, dynamically typed scripting language with first class closures, and a garbage-collected interpreter for that language (see GUIDE.md for more information on using bread). The design goals for bread are as follows:

• Get a good grade on my final project in my programming languages class

Building bread

bread has no dependencies outside of the C standard library, so simply run

make release

to create an optimized build. The generated binary will be ./release/bread. To install bread, run

make install

By default bread will be installed in ~/.local/bin/bread. To run a bread file, the command is

bread file.brd

To start a REPL, just run bread with no arguments. You can run bread --help for more detailed usage information.
