If you double-click a project symbol declaration, the symbol editor
opens. I found that I was double-clicking on the comment field and
typing with the expectation that the comment would be updated, but
it was actually setting the initial focus to the label field.
With this change the symbol editor will focus the label, value, or
comment field based on which column was double-clicked.
The behavior for Actions > Edit Project Symbol and other paths to the
symbol editor are unchanged.
Also, disabled a wayward assert.
SourceGen Edit Commands is a feature that allows you to generate
commands into a file and have SourceGen apply them to the current
project. I'm not expecting this to be used by anyone but me, so
for now I'm just adding an entry to the debug menu that can read
comments out of a file.
Also, fixed a bug in the re-centering min/max code that prevented
it from working on trivial shapes.
Also, renamed the atari-avg visualizer to atari-avg-bz, with the
expectation that one day somebody might want to create a variant
for newer games.
This converts AVG commands to wireframes. We don't try to track
color or intensity. (This is a disassembler, not a graphics
converter; perfection is not required.) The various rotation and
animation options are still enabled, though they're not terribly
useful for this.
Commands that are meant to be used in series, such as font glyphs,
tend to use (0,0) as their left edge and baseline. This puts the
shape in the upper-right corner of the thumbnail, which makes
everything smaller. The change adds a "re-center" option to the
wireframe renderer that computes the visible bounds and adjusts
the coordinates so that the center of the object is at (0,0) for
display.
This allows rendering of a vertex directly, rather than just as an
edge endpoint. They're currently drawn as small '+' signs. A
round dot would be better, but the code is passing a list of line
segments around, so this is simpler.
The code was wrong, but due to aggressive auto-label generation, it
rarely had an opportunity to express itself. The problem appeared
when you formatted a 16-bit value as an address, but the address
was outside the file and not associated with a project/platform
symbol. This fixes the glitch and adds some logging.
- Freeze Note brushes, so HTML export doesn't blow up when it tries
to access them.
- Add Ctrl+Shift+E as keyboard shortcut for File > Export.
- For code/data percentage, count inline data as data.
- Tweak code/data percentage text.
- Document Merlin32 '{' bug.
- Tweak tutorial text.
Don't show adjustments for operands that aren't full addresses. For
example, "LDA BLAH" shows an adjustment, but "LDA #>BLAH" does not.
This matches the behavior for internal addresses.
When generating the HTML anchor name element we need to remove the
trailing '?' from the label. It wasn't present in the hrefs, so all
links to annotated labels were broken.
The change to properly display adjustments to project/platform
symbol cross-references also added them to constants, but based on
the reference address rather than the operand value. We could
generate an adjustment from the value, but I'm not sure if that's
actually useful.
We were trying to use the in-file calculation for an external
address, so the adjustment was always zero.
Also, don't pass a fill brush for wireframe rendering. (No change
in behavior.)
Generation of HTML is extremely fast, but compressing thousands
of frames for wireframe animated GIFs can take a little while.
Sharing bitmaps between threads required two changes: (1) bitmaps
need to be "frozen" after being drawn; (2) you can't use Path because
BackgroundWorker isn't a STAThread. You can, however, use a
DrawingVisual / DrawingContext to do the rendering. Which is really
what I should have been doing all along; I just didn't know the
approach existed until I was forced to go looking for it.
Also, we now do a "run finalizers" call before generating an animated
GIF. Without it things explode after more than 10K GDI objects have
been allocated.
There's no "standard" coordinate system, so the choice is arbitrary.
However, an examination of the Transporter mesh in Elite revealed
that the mesh was designed for a left-handed coordinate system. We
can compensate for that trivially in the Elite visualizer, but we
might as well match what they're doing. (The only change required
in the code is a couple of sign changes on the Z coordinate, and an
update to the rotation matrix.)
This also downsizes Matrix44 to Matrix33, exposes the rotation mode
enum, and adds a left-handed ZYX rotation mode.
This does mean that meshes that put the front at +Z will show their
backsides initially, since we're now oriented as if we're flying
the ships rather than facing them. I considered adding a 180-degree
Y rotation (with a tweak to the rotation matrix handedness to correct
the first rotation axis) to have them facing by default, but figured
that might be confusing since +Z is supposed to be away.
Anybody who really wants it to be the other way can trivially flip
the coordinates in their visualizer (negate xc/zc).
The Z coordinates in the visualization test project were flipped so
that the design is still facing the viewer at rotation (0,0,0).
Elite has a level-of-detail cutoff in the mesh data. This change
provides a way for the visualization generator to exclude vertices
and edges that should not be rendered based on the desired LOD.
Experimented with different orders of rotation for wireframe viewer.
Made perspective projection the default behavior. Removed animation
parameters from the stored Visualization when it's not animated.
The visualization editor uses the parameters from the most recent
edit as the defaults when creating a new visualization. This change
extends the behavior to the view controls for wireframes.
Also, tweak the perspective projection scaling to fill out the area
a bit more, and change the visualization editor to use the grid's
size when setting the path dimensions.
Also, note gimbal lock.
Remember how object references from plugins are proxy objects that
time out if you don't access them for a while? I didn't either.
This reshuffles the code to keep WireframeObject references rather
than IVisualizationWireframe.
Handle the remaining visualization editor UI controls, except for
the "test" button. Save/restore wireframe animations in the
project file. Changed the preview from a 1-pixel-wide line drawn
by a path half the window size to a 2-pixel-wide line drawn by a
path the exact window size.
Moved X/Y/Z rotation out of the plugin, since it has nothing to do
with the plugin at all. (Backface removal and perspective projection
are somewhat based on the data contents, as is the choice for
whether or not they should be options.)
Added sliders for X/Y/Z rotation. Much more fun that way.
Renamed VisualizationAnimation to VisBitmapAnimation, as we're not
going to use it for wireframe animation. Created a new class to
hold wireframe animation data, which is really just a reference to
the IVisualizationWireframe so we can generate an animated GIF
without having to pry open the plugin again.
Renamed the "frame-delay-msec" parameter, which should start with
an underscore to ensure it doesn't clash with plugin parameters.
If we don't find it with an underscore we check again without for
backward compatibility.
We extract the data from the wireframe visualization, perform a
trivial transform, and display it. The perspective vs.
orthographic flag in the parameters is respected. (No rotation or
backface removal yet.)
Also, increased the thumbnail sizes in the visualization set editor
list from 48x48 to 64x64, because the nearest-pixel-scaled 48x48
looks nasty when used for wireframes.
I did a bunch of experiments to characterize line drawing. Long
story short: end points are inclusive, and coordinates should be
offset by +0.5 to avoid anti-aliasing effects.
Added some more plumbing. Updated visualization set edit dialog,
which now does word-wrapping correctly in the buttons. Added Alt+V
as the hotkey for Create/Edit Visualization Set, which allows you
to double-tap it to leap into the visualization editor.
Experimented with Path drawing, which looks like it could do just
what we need.
Also, show the file size in KB in the code/data/junk breakdown at the
bottom of the window. (Technically it's KiB, but that looked funny.)
These were being overlooked because they didn't actually cause
anything to happen (a no-op .ORG sets the address to what it would
already have been). The assembly source generator works in a way
that causes them to be skipped, so everybody was happy.
This seemed like the sort of thing that was likely to cause problems
down the road, however, so we now split regions correctly when a
no-op .ORG is encountered. This affects the uncategorized data
analyzer and selection grouping.
This changed the behavior of the 2004-numeric-types test, which was
visibly weird in the UI but generated correct output.
Added the 2024-ui-edge-cases test to provide a place to exercise
edge cases when testing the UI by hand. It has some value for the
automated regression test, so it's included there.
Also, changed the AddressMapEntry objects to be immutable. This
is handy when passing lists of them around.
Added a new category "sprite sheet", which is essentially a more
generalized version of the bitmap font renderer. It has the full
set of options for col/row/cell stride and colors. (Issue #74,
issue #75)
Added a flag that flips the high bits on bitmaps. Sometimes data
is stored with the high bit clear, but the high bit is set as it's
rendered. (Issue #76)
Also, fixed the keyboard shortcuts in the Edit Visualization Set
window, which were 'N' for both "New ___" items. (Issue #57)
Added accelerator keys to Mixed and Null strings. (Issue #67)
Added units to string counts. (Issue #68) Added proper handling
for plural/singular for bytes and strings. Changed N/A indicator
from "xx" to "--".
Added "show undocumented opcodes" checkbox, so you can choose
whether or not to see them at all. (Issue #60)
Added formatter call for the instruction mnemonics so they get
capitalized when the app is configured for upper-case opcodes.
(Issue #59)
Fix a bug where the instruction chart and ASCII chart were writing
their modes to the same setting, stomping each other.
Also, pluralized a button in the file concatenator.
For some reason FormatHexValue was creating format strings on
demand. In a recent change, FormatAdjustment started using them.
So if the first 4-digit hex value printed by the program was a
large adjustment, you could end up with a default-formatted adjustment
pretending to be hex.
Now we just create the 4 format strings in the Formatter constructor.
For nonzero values we were leaving Z=prev, which is wrong when Z=0
because the AND result might be zero. Now if Z=1 we leave it alone,
but if Z=0 we now set it to Z=?.
Test 1003-flags-and-branches was testing for the (incorrect)
behavior, so we're now running into a BRK. This is fine.
