Full bytecode compiler and interpreter for the Lox language, as explained by the Crafting Interpreters book by Robert Nystrom.
This is effectively a 1:1 copy of the source code snippets contained in the book. No additional functionality has been added.
It passes all tests and is even a bit faster than the reference implementation.
Here is a brief summary of what I changed:
- More aggressive inlining, which improves performance by about 8%.
- snake_case instead of camelCase. Not a big deal, just personal preference.
Other than that, this version doesn't include the markup comments from the book, so this code should be a little easier to read.
I don't plan to work on this project any further. Instead, I'm going to rewrite it in C++ and use it as the basis for my own little scripting language, which may end up in its own repository later.
$ mkdir build
$ cd build
$ cmake ..
$ cmake --build .You can add --parallel <threads> to the last command should you wish to use multiple compile jobs.
