Virgil Dupras 28d5ebdc8a Make apps folder into a namespace 
To straighten out includes and to pave the way into zasm being part of
the same "include CFS" as parts, we make zasm includes namespaced.

Virgil Dupras 556be3f0ce zasm: allow for whitespace inside string literals 
Also, increase scratchpad size. It wasn't big enough for some
expressions in shell unit.

Virgil Dupras 6547e83f20 zasm: improve comma processing 
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 7083116379 zasm: remove JUMP_ prefixes 
They serve no purpose and make the code less flexible.

Virgil Dupras 2f0dd5d668 zasm: iiiiiiiincluuuuuuudes!!1! 2019-05-16 21:15:00 -04:00
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.
