Similar to the ProDOS 8 formatter, but slightly more complex due
to the variable-length parameter block layout.
Also, added Orca shell call numbers to the list of constants.
Implemented Apple II hi-res bitmap conversion. Supports B&W and
color. Uses essentially the same algorithm as CiderPress.
Experimented with displaying non-text items in ListView. I assumed
it would work, since it's the sort of thing WPF is designed to do,
but it's always wise to approach with caution. Visualization Sets
now show a 64x64 button as a placeholder for the eventual thumbnail.
Some things were being flaky, which turned out to be because I
wasn't Prepare()ing the plugins before using them from Edit
Visualization. To make this a deterministic failure I added an
Unprepare() call that tells the plugin that we're all done.
NOTE: this breaks all existing plugins.
Sort of silly to have every handler immediately pull the operand out
of the file data. (This is arguably less efficient, since we now
have to serialize the argument across the AppDomain boundary, but
we should be okay spending a few extra nanoseconds here.)
We were failing to update properly when a label changed if the label
was one that a plugin cared about. The problem is that a label
add/remove operation skips the code analysis, and a label edit skips
everything but the display update. Plugins only run during the code
analysis pass, so changes weren't being reflected in the display
list until something caused it to refresh.
The solution is to ask the plugin if the label being changed is one
that it cares about. This allows the plugin to use the same
wildcard-match logic that it uses elsewhere.
For efficiency, and to reduce clutter in plugins that don't care
about symbols, a new interface class has been created to handle the
"here are the symbols" call and the "do you care about this label"
call.
The program in Examples/Scripts has been updated to show a very
simple single-call plugin and a slightly more complex multi-call
plugin.
The current AddressMap is now passed into the plugin manager, which
wraps it in an AddressTranslate object and passes that to the
plugins at Prepare() time. This allows plugins to convert addresses
to offsets, making it possible to format complex structures.
This breaks existing plugins.
We were providing platform symbols to plugins through the PlatSym
list, which allowed them to find constants and well-known addresses.
We now pass all project symbols and user labels in as well. The
name "PlatSym" is no longer accurate, so the class has been renamed.
Also, added a bunch of things to the problem list viewer, and
added some more info to the Info panel.
Also, added a minor test to 2011-hinting that does not affect the
output (which is the point).
Instead of providing no-op CheckJsr/CheckJsl, plugins now declare
which calls they support by defining interfaces on the plugin class.
I added a CheckBrk call for code like Apple /// SOS calls, which
use BRK as an OS call mechanism. The formatting doesn't work quite
right yet because I've been treating BRK as a two-byte instruction.
Hardly anything else does, and I think it's time I stopped (but not
in this commit).
Note: THIS BREAKS ALL PLUGINS that use the inline JSR/JSL feature,
which is pretty much all of them.
