# `ink`

`ink` is a minimalistic interpreted programming language, tentatively implemented exclusively in C89. It features 
coroutines and can currently only manipulate integers. Part of the code may not be compliant with C89 and I will try to 
fix that in time.

It is fully self-contained and doesn't rely on a working standard library beyond the following:

- `malloc`
- `realloc`
- `free`
- `putchar`

To make the library not use the standard library, build it with `NOSTDLIB` defined as a preprocessor directive.

All of these functions need to work for `ink` to work. It is easy to add new functions to the interpreter. I added a 
garbage collector to handle cleaning dynamically allocated resources.

It is possible to segregate unsafe allocations (allocations that should be hidden from the interpreter) by setting the 
`inner_` versions of the library functions to different allocation functions. 

## Limits

- Token size is limited to 127 bytes (see `ink_lex`)
- Values and indices are limited to the platform size of `int`
- Main function has a size limit of 256 tokens (see `ink_compile`)
- Functions have a size limit of 256 tokens (see `ink_parse`)
- Functions have a count limit 128 labels (see `ink_parse`)
- Only non-main functions can use labels
