- 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.
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.)
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.
(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.
Correct handling of local variables. We now correctly uniquify them
with regard to non-unique labels. Because local vars can effectively
have global scope we mostly want to treat them as global, but they're
uniquified relative to other globals very late in the process, so we
can't just throw them in the symbol table and be done. Fortunately
local variables exist in a separate namespace, so we just need to
uniquify the variables relative to the post-localization symbol table.
In other words, we take the symbol table, apply the label map, and
rename any variable that clashes.
This also fixes an older problem where we weren't masking the
leading '_' on variable labels when generating 64tass output.
The code list now makes non-unique labels obvious, but you can't tell
the difference between unique global and unique local. What's more,
the default type value in Edit Label is now adjusted to Global for
unique locals that were auto-generated. To make it a bit easier to
figure out what's what, the Info panel now has a "label type" line
that reports the type.
The 2023-non-unique-labels test had some additional tests added to
exercise conflicts with local variables. The 2019-local-variables
test output changed slightly because the de-duplicated variable
naming convention was simplified.
Added serialization of non-unique labels to project files.
The address labels are stored without the non-unique tag, because we
can get that from the file offset. (If we stored it, we'd need to
extract the value and verify that it matches the offset.) Operand
weak references are symbolic, and so do include the tag string.
We weren't validating symbol labels before. Now we are.
This also adds a "NonU" filter to the Symbols window so the labels
can be shown or hidden as desired.
Also, added source for a first pass at a regression test.
Jumps to the first offset associated with the change at the top of
the Undo stack. We generally jump to the code/data offset, not the
specific line affected. It's possible to do better (and we do, for
Notes), but probably not worthwhile.
As noted in issue #52, the side panels can't be resized once the
ListView gets focus. The root of the problem is a workaround for a
selection problem that involves catching the Item Container
Generator's Status Changed event, and setting an item's focus. It
appears that changing the size of the ListView causes the
StatusChanged event to fire, which cause the handler to grab the
focus, which causes the splitters to stop moving after one step.
This change adds a workaround that prevents the original workaround
from doing anything while a splitter is in the process of being
dragged. It doesn't solve all problems -- you can't move the
splitters more than one step with the keyboard -- but it allows them
to be dragged around with the mouse.
There's got to be a better way to deal with this.
If we detect a problem that requires intervention during loading,
e.g. we find unknown elements because we're loading a file created
by a newer version, default to read-only mode.
Read only mode (1) refuses to apply changes, (2) refuses to add
changes to the undo/redo list, and (3) disables Save/SaveAs. The
mode is indicated in the title bar.
Also, flipped the order of items in the title bar so that "6502bench
SourceGen" comes last. This allows you to read the project name in
short window title snippets. (Visual Studio, Notepad, and others
do it this way as well.)
Not a huge improvement, but things are slightly more organized, and
there's a splash of color in the form of a border around the text
describing the format of code and data lines.
Added an "IsConstant" property to Symbol.
Mark the "info" window as read-only.
When the project closes, clear the contents of the Symbols and
Notes windows.
Clarify some Apple II I/O definitions.
This adds a window that displays all of the instructions for a
given CPU in a summary grid. Undocumented instructions are
included, but shown in grey italics.
Also, tweaked AppSettings to not mark itself as dirty if a "set"
operation doesn't actually change anything.
Implemented show/hide mechanic, using a button on the right side of
the status bar to show status and to trigger un-hide.
Also, show I/O direction in project symbols editor list.
This converts the "problem list viewer" tool to a grid that appears
below the code list view when non-empty. Not all messages are
problems, so it's being renamed to "message list".
Created a Navigate menu, and put the menu items for Find and Go To
in it. Added menu items for nav-forward and nav-backward, which
until now were only available as toolbar buttons.
Most of SourceGen uses standard WPF controls, which get their default
style from the system theme. The main disassembly list uses a
custom style, and always looks like the Windows default theme.
Some people greatly prefer white text on a black background, so we
now provide a way to get that. This also requires muting the colors
used for Notes, since those were chosen to contrast with black text.
This does not affect anything other than the ListView used for
code, because everything else can be set through the Windows
"personalization" interface. We might want to change the way the
Notes window looks though, to avoid having glowing bookmarks on
the side.
The Find box now has forward/backward radio buttons. Find Next
searches forward, and Find Previous searches backward, regardless
of the direction of the initial search.
The standard key sequence for "find previous" is Shift+F3. The WPF
ListView has some weird logic that does something like: if you hit
a key, and the selection changes, and the shift key was held down,
then you must have meant to select a range. So Shift+F3 often (but
not always) selects a range. I think this might be fixable if I can
figure out how ListView keeps track of the current keyboard
navigation position (which is not the same as the selection). For
now I'm working around the problem by using Ctrl+F3 to search.
Yay WPF.
We were changing the control template for lines with long comments
and notes, matching the default Win10 style. This got ugly when a
non-default theme was being used, particularly "dark" themes,
because the long-comment lines looked significantly different from
everything else.
We now fully specify the style for the ListView and ListViewItems,
which means everybody's main window now looks like the default Win10
style. Which is unfortunate, but significantly easier than creating
a full set of theme-specific styles.
We now specify black text for highlighted address/label fields,
because they otherwise become illegible when we apply our background
highlight color. In the Notes window, we set the background of
un-highlighted entries to white, so that we can always read it with
black text.
Addresses issue #50.
Added a Width column to the list in the project symbol editor.
Changed the local variable table editor and the project symbol editor
to use DataGrid instead of ListView. This gets us easy sorting on
arbitrary columns. The previous code was reloading the display list
after every change; now we just add/edit/remove individual items,
which helps keep the list position and selection stable.
The analyzer sometimes runs into things that don't seem right, like
hidden labels or references to non-existent symbols, but has no way
to report them. This adds a problem viewer.
I'm not quite ready to turn this into a real feature, so for now it's
a free-floating window accessed from the debug menu.
Also, updated some documentation.
Split "edit local variable table" into "create" and "edit prior".
The motivation is to allow the user to make changes to the most
recently defined table without having to go search for it. Having
table creation be an explicit action, rather than something that
just happens if you edit a table that isn't there, feels reasonable.
Show table offset in LV table edit dialog, so if you really want
to go find it there's a (clumsy) way to do so.
Increased the maximum width of a variable from 4 to 8. (This is
entirely arbitrary.)
Ported the column width stuff from EditAppSettings, which it turns
out can be simplified slightly.
Moved the clipboard copy code out into its own class.
Disabled "File > Print", which has never done anything and isn't
likely to do anything in the near future.
Also, added a note to 2019-local-variables about a test case it
should probably have.
- Updated the tutorial to track changes to WPF, and to clarify
existing content.
- Fixed Ctrl+H Ctrl+C, which was getting masked by the Copy command
handler.
- Fixed initial selection of address in Set Address.
- MakeDist now copies CommonWPF.dll.
- Spent a bunch of time tracking down a null-pointer deref that only
happened when you didn't start with a config file. Fixed.
- The NPE was causing the program to exit without any sort of useful
diagnostic, so I added an uncaught exception handler that writes
the crash to a text file in the current directory.
- Added a trace listener definition to App.config that writes log
messages to a file, but it can't generally be enabled at runtime
because you can't write files from inside the sandbox. So it's
there but commented out.
- Made the initial size of the main window a little wider.
