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".
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.
If you select a local variable, double-click on a reference entry,
and then hit "back", you aren't taken back to the correct place in
the local variable table. This is annoying if you're trying to
explore how a local variable is used.
The NavStack Location object now has a "line delta" that can be
applied to position the selection correctly. This isn't stable
across undo/redo, but it solves the common cases.
This makes LineListGen's "Top" class redundant, so uses of that have
been replaced with Location.
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.
Implement multi-byte project/platform symbols by filling out a table
of addresses. Each symbol is "painted" into the table, replacing
an existing entry if the new entry has higher priority. This allows
us to handle overlapping entries, giving boosted priority to platform
symbols that are defined in .sym65 files loaded later.
The bounds on project/platform symbols are now rigidly defined. If
the "nearby" feature is enabled, references to SYM-1 will be picked
up, but we won't go hunting for SYM+1 unless the symbol is at least
two bytes wide.
The cost of adding a symbol to the symbol table is about the same,
but we don't have a quick way to remove a symbol.
Previously, if two platform symbols had the same value, the symbol
with the alphabetically lowest label would win. Now, the symbol
defined in the most-recently-loaded file wins. (If you define two
symbols with the same value in the same file, it's still resolved
alphabetically.) This allows the user to pick the winner by
arranging the load order of the platform symbol files.
Platform symbols now keep a reference to the file ident of the
symbol file that defined them, so we can show the symbols's source
in the Info panel.
These changes altered the behavior of test 2008-address-changes,
which includes some tests on external addresses that are close to
labeled internal addresses. The previous behavior essentially
treated user labels as being 3 bytes wide and extending outside the
file bounds, which was mildly convenient on occasion but felt a
little skanky. (We could do with a way to define external symbols
relative to internal symbols, for things like the source address of
code that gets relocated.)
Also, re-enabled some unit tests.
Also, added a bit of identifying stuff to CrashLog.txt.
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.
Variables are now handled properly end-to-end, except for label
uniquification. So cc65 and ACME can't yet handle a file that
redefines a local variable.
This required a bunch of plumbing, but I think it came out okay.
String operands used to be simple -- each line had 62 characters
plus two hard-coded non-ASCII delimiters -- but now we're mixing
character and hex data, so we can't use simple math to tell where
the lines will break. We want to render them and keep the result
around until some dependency changes, e.g. different delimiters
or a change to the pseudo-op table.
Also, cleaned up LineListGen a little. It had some methods that
were declared static because they were expected to be shared, but
that never happened.
Also, fixed a bug in GatherEntityCounts where multi-line items were
being scanned multiple times.
- 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.
