I care a lot about being able to automatically check any property about my program before it ever runs. However, some things don't have tests yet, either because I don't know how to test them or because I've been lazy. I'll at least record those here.

Compromises

Lua is dynamically typed. Tests can't patch over lack of type-checking.

• All strings are UTF-8. Bytes within them are not characters. I try to label byte offsets as _offset, and character positions as _pos. For example, string.sub should never use a _pos to substring, only an _offset.

Todo list

resize: create a file containing a long line of characters without spaces. try resizing the window vertically and horizontally, as far as possible.
