The handful of 6502-based Atari coin-op systems were very different
from each other, so having a dedicated entry doesn't make sense.
Also, enable word-wrap in the New Project text box that holds the
system description.
Changed bank-start comments to notes, added a summary to the top-of-file
comment.
Also, fixed a bug where the app settings dialog wasn't identifying
display settings as a preset for 64tass and cc65.
It's nice to be able to save images from the visualization editor
for display elsewhere. This can be done during HTML export, but
that's inconvenient when you just want one image, and doesn't allow
the output size to be specified.
This change adds an Export button to the Edit Visualization dialog.
The current bitmap, wireframe, or wireframe animation can be saved
to a GIF image. A handful of sizes can be selected from a pop-up
menu.
If you double-click on the opcode of an instruction whose operand is
an address or equate, the selection jumps to that address. This
feature is now available in the Navigate menu, with the keyboard
shortcut Ctrl+J.
While testing the feature I noticed that the keyboard focus wasn't
following the selection, so if you jumped to an address and then
used the up/down arrows, you jumped back to the previous location.
(This was true when double-clicking an opcode to jump; it was just
less noticeable since the next action was likely mouse-based.) This
has been fixed by updating the ListView item focus when we jump to a
new location.
See also issue #63 and issue #72.
Some tests were duplicated between VisWireframe and the code that
consumed the data. We now expose the Validate function as a public
interface, and invoke it from WireframeObject. Failed validation
results in a null object being returned, which was previously allowed
but not actually checked for.
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.
- 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.
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.)
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 "--".
When editing an instruction operand, if you click "edit project
symbol", we need an initial value for the label. If you started
typing something in the instruction operand symbol field, we use
that. Unfortunately we were trying to use that even when it was
invalid, which caused an assertion to go off in the DefSymbol
constructor.
In 1.5.0-dev1, as part of changes to the way label localization
works, the local variable de-duplicator started checking against a
filtered copy of the symbol table. Unfortunately it never
re-generated the table, so a long-lived LocalVariableLookup (like
the one used by LineListGen) would set up the dup map wrong and
be inconsistent with other parts of the program.
We now regenerate the table on every Reset().
The de-duplication stuff also had problems when opcodes and
operands were double-clicked on. When the opcode is clicked, the
selection should jump to the appropriate variable declaration, but
it wasn't being found because the label generated in the list was
in its original form. Fixed.
When an instruction operand is double-clicked, the instruction operand
editor opens with an "edit variable" shortcut. This was showing
the de-duplicated name, which isn't necessarily a bad thing, but it
was passing that value on to the DefSymbol editor, which thought it
was being asked to create a new entry. Fixed. (Entering the editor
through the LvTable editor works correctly, with nary a de-duplicated
name in sight. You'll be forced to rename it because it'll fail the
uniqueness test.)
References to de-duplicated local variables were getting lost when
the symbol's label was replaced (due largely to a convenient but
flawed shortcut: xrefs are attached to DefSymbol objects). Fixed by
linking the XrefSets.
Given the many issues and their relative subtlety, I decided to make
the modified names more obvious, and went back to the "_DUPn" naming
strategy. (I'm also considering just making it an error and
discarding conflicting entries during analysis... this is much more
complicated than I expected it to be.)
Quick tests can be performed in 2019-local-variables:
- go to +000026, double-click on the opcode, confirm sel change
- go to +000026, double-click on the operand, confirm orig name
shown in shortcut and that shortcut opens editor with orig name
- go to +00001a, down a line, click on PROJ_ZERO_DUP1 and confirm
that it has a single reference (from +000026)
- double-click on var table and confirm editing entry
- Break up long sequences of visualization images in exported HTML
to avoid horizontal scrolling. Lines don't fold in "pre" mode,
and switching out of "pre" is ugly, so we just break at an
arbitrary point.
- Use a slightly different filename for animated GIFs.
- When moving items up/down in the visualization set editor or
bitmap animation editor, scroll the datagrid to keep the selected
item in view.
- Fix a wayward assert.
Remember the most recent set of parameters, and use them as defaults
when creating a new visualization. This is very helpful when
creating visualizations for multiple frames of an animation.
After exiting an editor, focus on the "OK" button in the visualization
set editor. This allows a quick double-Enter after an edit.
The tool allows you to cut a piece out of a file by specifying an
offset and a length. A pair of hex dumps helps you verify that the
positions are correct.
Also, minor cleanups elsewhere.
The visualization editor was retaining an IPlugin reference for the
visualization generator selection combo box. After 5 minutes the
proxy object timed out, so if you left the editor open and inactive
for that long you'd start getting weird errors.
We now keep the script identifier string and use that to get a
fresh IPlugin proxy object.
If you have a single line selected, Set Address adds a .ORG directive
that changes the addresses of all following data, until the next .ORG
directive is reached. Sometimes code will relocate part of itself,
and it's useful to be able to set the address at the end of the block
to what it would have been before the .ORG change.
If you have multiple lines selected, we now add the second .ORG to
the offset that follows the last selected line.
Also, fixed a bug in the Symbol value updater that wasn't handling
non-unique labels correctly.
As with still images, animations are rendered at original size and
then scaled with HTML properties.
Also, fixed the blurry scaling on animation thumbnails. I couldn't
find a way to do nearest-neighbor scaling in the code-behind without
resorting to System.Drawing (WinForms), so I added an overlay image
to the various grids.
Visualization animations are now exported as animated GIFs. The
Windows stuff is a bit lame so I threw together some code that
stitches a bunch of GIFs together.
The GIF doesn't quite match the preview, because the preview scales
the individual frames, while the animated GIF uses the largest frame
as the size and is then scaled based on that. Animating frames of
differing sizes together is bound to be trouble anyway, so I'm not
sure how much to fret over this.
We now store Visualizations, VisualizationAnimations, and
VisualizationSets as three separate lists linked by tag strings.
WARNING: this breaks existing projects with visualizations. The
test projects have been updated.
The UI was moving items from the source list to the animation list,
but there's no reason why the same thing can't appear more than once.
You can no longer hit "Add" repeatedly to add multiple consecutive
items, but you can now multi-select in the source list to add several
things at once.
Bitmap animations are composed of a sequence of other visualizations.
This is all well and good until a visualization is deleted, at which
point all animations in all sets in the entire project have to be
checked and potentially changed, and perhaps even removed (if all of
the animation's members have been removed). This turns out to be
kind of annoying to deal with, but it's better to deal with it in
code than force the user to manually update broken animations.
This change adds thumbnails for the animations, currently generated
by offscreen composition. This approach doesn't work quite right.
This adds a new class and a rough GUI for the editor. Animated
visualizations take a collection of bitmaps and display them in
sequence. (This will eventually become an animated GIF.)
Fixed the issue where changes to tags in the set currently being
edited weren't visible to the tag uniqueness check when editing other
items in the same set.
We now generate GIF images for visualizations and add inline
references to them in the HTML output.
Images are scaled using the HTML img properties. This works well
on some browsers, but others insist on "smooth" scaling that blurs
out the pixels. This may require a workaround.
An extra blank line is now added above visualizations. This helps
keep the image and data visually grouped.
The Apple II bitmap test project was updated to have a visualization
set with multiple images at the top of the file.
(1) Added an option to limit the number of bytes per line. This is
handy for things like bitmaps, where you might want to put (say) 3
or 8 bytes per line to reflect the structure.
(2) Added an application setting that determines whether the screen
listing shows Merlin/ACME dense hex (20edfd) or 64tass/cc65 hex bytes
($20,$ed,$fd). Made the setting part of the assembler-driven display
definitions. Updated 64tass+cc65 to use ".byte" as their dense hex
pseudo-op, and to use the updated formatter code. No changes to
regression test output.
(Changes were requested in issue #42.)
Also, added a resize gripper to the bottom-right corner of the main
window. (These seem to have generally fallen out of favor, but I
like having it there.)
- Show the full path in the tooltip for the two "recent project"
buttons shown on the launch panel.
- Reset the app title bar and status bar contents when the project
is closed.
Added comments, renamed files, removed cruft.
Stop showing the visualization tag name in the code list. It's
often redundant with the code label, and it's distracting. (We may
want to make this an option so you can Ctrl+F to find a tag.)
