Virgil Dupras 1dec33e02a zasm: make symbol registry a bit more straightforward 
Instead of strings of variable length driving the iteration of the
registry, we do so through records that keep track of lengths and
counts.

Virgil Dupras 311d04e9aa zasm: make symbol registry easily parametrizable 
I'm about to split the global registry in two (labels and consts)
and the previous state of registry selection made things murky.
Now it's much better.

Virgil Dupras 34f499184d zasm: add ".bin" directive 
Also, remove zasm/test7 because it changes too much all time time
(whenever zasm changes) and isn't precise enough. Too much noise,
not worth it.

Virgil Dupras 01031a780a ed: Add 'w' command 2019-07-21 11:40:26 -04:00
Virgil Dupras 942d2a952d ed: take filename as an argument 
This hard-binds ed to the filesystem (I liked the idea of working
only with blockdevs though...), but this is necessary for the
upcoming `w` command. We need some kind of way to tell the
destination to write to truncate itself.

This only has a meaning in the filesystem, but it's necessary to
let the file know that its registered file size has possibly
shrunk.

I thought of alternatives that would have allowed me to keep ed
blkdev-centered, but they were all too hackish to my own taste.

Hence, this new hard-bind on files.

Virgil Dupras fe15bafeca zasm: fix bug with registry selection 
During expression parsing, if a local label was parsed, it would
select the local registry and keep that selection, making
subsequent global labels register in the wrong place.

Virgil Dupras a7afbe091e tools/tests: remove scas requirement 
I'm about to break compatibility with scas. Before I do that, I
need to adjusts tests. Instead of running scas to compare results,
we commit expected result as binaries directly in the repo.

Virgil Dupras c18d42f08b fs: further adjust to previous blkdev refactoring 
Previous refacoring broke all seek/tell within fs. fs handles now lost
the responsibility to keep track of current position. It's blkdev's job.

Virgil Dupras ae028e3a86 blockdev: make implementors "random access" 
This huge refactoring remove the Seek and Tell routine from blockdev
implementation requirements and change GetC and PutC's API so that they
take an address to read and write (through HL/DE) at each call.

The "PTR" approach in blockdev implementation was very redundant from
device to device and it made more sense to generalize. It's possible
that future device aren't "random access", but we'll be able to add more
device types later.

Another important change in this commit is that the "blockdev handle" is
now opaque. Previously, consumers of the API would happily call routines
directly from one of the 4 offsets. We can't do that any more. This
makes the API more solid for future improvements.

This change forced me to change a lot of things in fs, but overall,
things are now simpler. No more `FS_PTR`: the "device handle" now holds
the active pointer.

Lots, lots of changes, but it also feels a lot cleaner and solid.

Virgil Dupras 63473cc2e3 blockdev: make selection structure opaque 
I'm about to change that structure and I don't want fs to be messed up
by this. I'm proceeding step by step...
