We don't treat "," exactly as a whitespace anymore. We have specific
processing for it.

Virgil Dupras 0f5fab23e9 zasm: don't accept "0X" prefix for hex anymore 
This was only necessary in the time where input was upcased right after
reading.

Virgil Dupras 4075c90d44 Add unit test for zasm's parse unit 2019-05-17 10:00:30 -04:00
Virgil Dupras 7083116379 zasm: remove JUMP_ prefixes 
They serve no purpose and make the code less flexible.
 2019-05-17 09:50:11 -04:00
Virgil Dupras 013a3b74c8 Add the concept of unit tests 
Will be much much easier to tests new core routines without having to
re-create their context first.

Also, extract parse.asm from core.asm

Virgil Dupras ede228374c fs: allow fsNext to skip more than one block 
When B>1, fsNext failed because HL was changed in the Seek call.

Virgil Dupras 23f0dc18ca zasm emul: add tooling for includes fsdev 
On build, pack `parts/z80` into a CFS and embed it into the emulated
zasm executable as an fsdev. This will allow for the upcoming include
directive to have something to go to.

For now, this is useless except for inflating the emulated zasm's size.

Virgil Dupras 22c7eeaa5d Move apps/zasm/tests to tools/tests/zasm 
This 'apps' folder is going to disappear. Everything is going to be a
"part" to be assembled through recipes. 'apps' has no meaning.

Virgil Dupras 0ae91e55ec zasm: big local symbols overhaul 2019-05-16 08:26:00 -04:00
Virgil Dupras e9244b80ee zasm: big I/O overhaul 
Instead of buffering input in memory one line at a time, we go in "just
in time" mode and always read contents directly from I/O, without
buffering.

It forces us to implement a `ioPutback` scheme, but on the other hand it
greatly simplifies cases where multiple tokens are on the same line
(when a label is directly followed by an instruction).

The end result feels much more solid and less hackish.

Virgil Dupras a2b5b1efab zasm: add one layer of indirection in symbol registry 
We'll need it for an upcoming "local labels" registry.

Virgil Dupras dd6fa5d38b zasm: properly propagate error conditions 
Gives clearer output on errors. Easier debugging...

Virgil Dupras 86cad39de4 zasm: fix wrong logic in .numberTruncated error condition 
`xor c` didn't do what I thought it did at the time. Newbie mistake,
there are probably a lot like this scattered around...
