2021-02-28 r/2247 feat(tazjin/rlox): Wire up bytecode interpreter & print resultsVincent Ambo1-4/+7

2021-01-19 r/2132 refactor(tazjin/rlox): Prepare scanner for shared useVincent Ambo1-0/+1
In the book, the clox interpreter has its own scanner which uses a pull-based model for a single pass compiler. I can't be bothered to write another scanner, or amend this one into pull-mode to work with the treewalk interpreter, so instead I will just reuse it and pull from a vector of tokens. The tokens are shared between both interpreters and the scanner is not what I'm interested in here.

2021-01-17 r/2126 chore(tazjin/rlox): Move other modules under treewalk::Vincent Ambo1-9/+0
It's unclear if the second part of the book can reuse anything from the first part (I'm guessing probably the scanner, but I'll move that back if it turns out to be the case).

2021-01-17 r/2118 refactor(tazjin/rlox): Call resolver from interpreterVincent Ambo1-2/+1
This makes the interpreter API a bit cleaner and allows for tighter integration between the two parts (e.g. for static globals, which are unhandled in the resolver right now).

2021-01-16 r/2113 feat(tazjin/rlox): Implement variable depth resolverVincent Ambo1-11/+8
Implements the first part of the resolver from https://craftinginterpreters.com/resolving-and-binding.html This is wired up to the execution paths in main, but not yet in the tests. The resolved depth is also not actually used for variable lookups (yet).

2021-01-14 r/2107 refactor(tazjin/rlox): Let scanner tokens own their lexemeVincent Ambo1-4/+5
This removes the runtime dependency on a borrow into the program source code. It's not yet ideal because there are a lot of tokens where we really don't care about the lexeme, but this is what the book does and I am not going to change that.

2021-01-14 r/2104 refactor(tazjin/rlox): Thread lifetimes through interpreterVincent Ambo1-5/+4
In order to store a function in the interpreter's representation of a callable, the lifetimes used throughout rlox need to be threaded through properly. This is currently not optimal, for two reasons: * following the design of the book's scanner, the source code slice needs to still be available at runtime. Rust makes this explicit, but it seems unnecessary. * the interpreter's lifetime is now bounded to be smaller than the source's, which means that the REPL no longer persists state between evaluations Both of these can be fixed eventually by diverging the scanner from the book slightly, but right now that's not my priority.

2020-11-23 r/1914 feat(tazjin/rlox): Implement single-character scanningVincent Ambo1-0/+2
... still not that interesting, but at this point slightly divergent from the book: The book embraces mutability for interpreter state, initially for tracking whether an error condition has occured. I avoid this by instead defining an error type and collecting the error values, to be handled later on. Notes: So far nothing special, but this is just the beginning of the book. I like the style it is written in and it has pointed to some interesting resources, such as a 1965 paper titled "The Next 700 Languages".
