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.
|
||||||
|
|
||||||
|
### 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
|
||||||
|
|
||||||
|
drawing
|
||||||
|
select a point and move it
|
||||||
|
select a point and name it
|
||||||
|
|
||||||
|
persistence:
|
||||||
|
draw a line, circle, rectangle, square, polygon, quit, restart. All the shapes you drew should still be visible.
|
||||||
|
select a point and name it, quit, restart. Name is still visible.
|
||||||
|
|
||||||
|
undo:
|
||||||
|
naming points
|
||||||
|
deleting points
|
||||||
|
moving points
|
||||||
|
|
||||||
|
resize:
|
||||||
|
create a file containing a long line of characters without spaces. try
|
||||||
|
resizing the window vertically and horizontally, as far as possible.

Wish I had some static typing here. We're not going to try to write tests to catch issues like this.
