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
