2ddd3b400d Workaround for GridSplitter lockup
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.

4b46b78e34 Rearrange the tutorial files
Copied the extension script tutorial files out of the Scripts
directory and into the Tutorial directory.  This makes more sense,
and makes it possible to expand the script sample without altering
the tutorial.

Reverted the Scripts sample to be an actual sample, rather than a
tutorial.

Renumbered the last two tutorials and added them to the ToC.  This
gives them actual numbers rather than treating them as add-ons to
the advanced tutorial.

Moved the source files for the tutorial binaries into a subdirectory
to reduce clutter.

This does mean we have two separate copies of the inline string
sample plugins, but that's an artifact of our attempts at security.

51081c5db0 Tweak "nearby" label finder
The code that found a nearby data target for an instruction operand
was searching backward but not forward.  We now take one step
forward, so that "LDA TABLE-1,Y" fills in automatically.

This altered 2008-address-changes, which had just this situation.
It didn't alter 2010-target-adjustment, but the existing tests were
insufficient and have been improved.

7000a5094e Fix crashing bug in selection management
The fix for Shift+F3 required briefly switching the code list view
to single-select mode.  Unfortunately, while in that mode the
control throws an exception if you touch SelectedItems (plural)
rather than SelectedItem (singular), and in an unusual case the
selection-changed event handler was doing just that.

14ecad0849 Improve handling of hidden LV tables
If a local variable table gets buried, it won't appear in the code
list, so most things ignore it.  Unfortunately, the code that adds
new entries and edits tables was finding them, which was causing
variable definitions to appear to fall into a black hole.

This is addressed in two ways.  First, we now add a message to the
log when a hidden table is noticed.  Second, the code that finds
the nearest prior table now keeps track of hidden vs. not hidden.
If a non-hidden table is available, that is returned.  If the only
option is a hidden table, we will return that, because the callers
have already assumed that a table exists by virtue of its presence
in the LvTable list.

0fc121c9cb Add ability to "erase" previously-defined platform symbols
While disassembling some code I found that I wanted the ROM entry
points, but the zero page usage was significantly different and the
ROM labels were distracting.  Splitting the symbol file in two was
a possibility, but I'm afraid this will lead to a very large
collection of very small files, and we'll lose any sense of relation
between the ROM entry points and the ZP addresses used to pass
arguments.

Platform symbols have the lowest priority when resolving by address,
but using that to hide the unwanted labels requires creating project
symbols or local variables for things that you might not know what
they do yet.  It's possible to hide a platform symbol by adding
another symbol with the same label and an invalid value.

This change formalizes and extends the "hiding" of platform symbols
to full erasure, so that they don't clutter up the symbol table.
This also tightens up the platform symbol parser to only accept
values in the range 0 <= value <= 0x00ffffff (24-bit positive
integers).

An "F8-ROM-nozp" symbol file is now part of the standard set.  A
project can include that to erase the zero-page definitions.

(I'm not entirely convinced this is the right approach, so I'm not
doing this treatment on other symbol files... consider this an
experiment.  Another approach would be some sort of conditional
inclusion, or perhaps erase-by-tag, but that requires some UI work
in the app to define what you want included or excluded.)

d99eec0d4f Open damaged projects in read-only mode
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.)

1844fcb8b7 Fix junk alignment check
While adding a message log entry for failing alignment directives,
I noticed that the assembler source generator's test for valid
alignment was allowing some bad alignment values through.

I'm holding off on reporting the message to the log because not all
format changes cause a data-reanalysis, which means the log entry
doesn't always appear and disappear when it should.  If we decide
this is an important message we can add a scan for "softer" errors.

1b0ee7de21 Fix display of instruction attributes
The "affected flags" constants were incorrect for BIT, BRK, COP,
RTI, XCE, and the undocmented instructions ANE, DCP, and SAX.  The
constants are used for the changed-flag summary shown in the info
window and the instruction chart.

Of greater import: the status flag updater for BIT was incorrectly
marking N/V/C as indeterminate instead of N/V/Z.  The undocmented
instructions ANE, DCP, and SAX were also incorrect.

The cycle counts shown in line comments are computed correctly, but
the counts shown in the info window and instruction chart were
displaying the full set of modifiers, ignoring the CPU type.  That's
okay for the info window, which spells the modifiers out, though
it'd be better if the bits were explicitly marked as being applicable
to the current CPU or a different one.

b6e571afc2 Correctly handle embedded instruction edge case
This began with a change to support "BRK <operand>" in cc65.  The
assembler only supports this for 65816 projects, so we detect that
and enable it when available.

While fiddling with some test code an assertion fired.  This
revealed a minor issue in the code analyzer: when overwriting inline
data with instructions, we weren't resetting the format descriptor.

The code that exercises it, which requires two-byte BRKs and an
inline BRK handler in an extension script, has been added to test
2022-extension-scripts.

The new regression test revealed a flaw in the 64tass code
generator's character encoding scanner that caused it to hang.
Fixed.

cd23580cc5 Add junk/align directives
Sometimes there's a bunch of junk in the binary that isn't used for
anything.  Often it's there to make things line up at the start of
a page boundary.

This adds a ".junk" directive that tells the disassembler that it
can safely disregard the contents of a region.  If the region ends
on a power-of-two boundary, an alignment value can be specified.

The assembly source generators will output an alignment directive
when possible, a .fill directive when appropriate, and a .dense
directive when all else fails.  Because we're required to regenerate
the original data file, it's not always possible to avoid generating
a hex dump.

fac2d6a51f Invoke extension scripts when labels they care about change
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.

3702448780 Correctly handle a label update edge case
Test case:
 1. create a label FOO
   (can be referenced or unreferenced)
 2. add a platform symbol file that also defines FOO
   (the platform symbol will be masked by the user label)
 3. rename FOO to BAR
   (platform symbol should appear)
 4. hit "undo"
   (platform symbol should disappear)
 5. delete label FOO
   (platform symbol should appear)
 6. hit "undo"
   (platform symbol should disappear)

This will fail to update the display list properly, and/or crash
when we try to add FOO to a symbol table that already has a
symbol with that label.

The problem is the optimization that tries to avoid running the
data analysis pass if we're just renaming a user label.  We need to
check to see if the rename overlaps with project/platform symbols,
because we need to update the active def symbol set in that case.

To avoid the crash, we just need to use table[key]=value syntax
instead of table.Add(key,value).

df2f3803f4 SourceGen After Dark
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.

d8604294bb Change how the "quick set" settings work
The last two tabs in the Edit App Settings dialog have "quick set"
buttons configure all fields for a particular assembler, or reset
them to default values.  The previous UI was a little annoying,
because you had to pick something from the combo box and then hit
"set" to push the change.  It was also confusing, because if you
came back later the combo box was just set to the first entry, not
the thing you picked last.

Now, picking an entry from the combo box immediately updates all
fields.  The combo box selection is set to reflect the actual
contents (so if you set everything just right, the combo box will
change to a specific assembler).  If nothing matches, a special
entry labeled "Custom" is selected.

Also, rearranged the tutorial sections in the manual so the
address table formatting comes last, and appears in the local TOC.

If you select a local variable, double-click on a reference entry,

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.

3a67c14247 Add "find previous"
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.

dfd5bcab1b Optionally treat BRKs as two-byte instructions
Early data sheets listed BRK as one byte, but RTI after a BRK skips
the following byte, effectively making BRK a 2-byte instruction.
Sometimes, such as when diassembling Apple /// SOS code, it's handy
to treat it that way explicitly.

This change makes two-byte BRKs optional, controlled by a checkbox
in the project settings.  In the system definitions it defaults to
true for Apple ///, false for all others.

ACME doesn't allow BRK to have an arg, and cc65 only allows it for
65816 code (?), so it's emitted as a hex blob for those assemblers.
Anyone wishing to target those assemblers should stick to 1-byte mode.

Extension scripts have to switch between formatting one byte of
inline data and formatting an instruction with a one-byte operand.
A helper function has been added to the plugin Util class.

To get some regression test coverage, 2022-extension-scripts has
been configured to use two-byte BRK.

Also, added/corrected some SOS constants.

b8e11215fa Add separate button for adding symbols+scripts from project
The "add platform symbol file" and "add extension script" buttons

This is great if you're trying to add a file from the platform

It's really convenient to not have to hunt around though, so now
there are two buttons: one for platform, one for project.  The
latter is disabled if the project is new and hasn't been saved yet.

e1a9100a8f Fully style the code list view
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.

8c87ce3004 Check formatted string structure at load time
If we have a bug, or somebody edits the project file manually, we
can end up with a very wrong string, such as a null-terminated
string that isn't, or a DCI string that has a mix of high and low
ASCII from start to finish.  We now check all incoming strings for
validity, and discard any that fail the test.  The verification
code is shared with the extension script inline data formatter.

Also, added a comment to an F8-ROM symbol I stumbled over.

Extension scripts (a/k/a "plugins") can now apply any data format

verifies the string structure (e.g. null-terminated strings have
exactly one null byte, at the very end).

Added PluginException to carry an exception back to the plugin code,
for occasions when they're doing something so wrong that we just
want to smack them.

37855c8f8e Allow explicit widths in project/platform symbols, part 4 (of 4)
Handle situation where a symbol wraps around a bank.  Updated
2021-external-symbols for that, and to test the behavior when file
data and an external symbol overlap.

The bank-wrap test turned up a bug in Merlin 32.  A workaround has
been added.

Updated documentation to explain widths.

Andy McFadden
0d9814d993 Allow explicit widths in project/platform symbols, part 3
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.

14150af004 Allow explicit widths in project/platform symbols, part 2
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.

Andy McFadden
2a41d70e04 Allow explicit widths in project/platform symbols, part 1
The ability to give explicit widths to local variables worked out
pretty well, so we're going to try adding the same thing to project
and platform symbols.

The first step is to allow widths to be specified in platform files,
and set with the project symbol editor.  The DefSymbol editor is
also used for local variables, so a bit of dancing is required.
For platform/project symbols the width is optional, and is totally
ignored for constants.  (For variables, constants are used for the
StackRel args, so the width is meaningful and required.)

We also now show the symbol's type (address or constant) and width
in the listing.  This gets really distracting when overused, so we
only show it when the width is explicitly set.  The default width
is 1, which most things will be, so users can make an aesthetic
choice there.  (The place where widths make very little sense is when
the symbol represents a code entry point, rather than a data item.)

The maximum width of a local variable is now 256, but it's not
allowed to overlap with other variables or run of the end of the
direct page.  The maximum width of a platform/project symbol is
65536, with bank-wrap behavior TBD.

The local variable table editor now refers to stack-relative
constants as such, rather than simply "constant", to make it clear
that it's not just defining an 8-bit constant.

Widths have been added to a handful of Apple II platform defs.

In a recent survey, three out of four cross assemblers surveyed

map that's part of the label localizer.

"JMP JMP JMP".

b74630dd5b Work around two assembler issues
Most assemblers end local label scope when a global label is
encountered.  cc65 takes this one step further by ending local label
scope when constants or variables are defined.  So, if we have a
variable table with a nonzero number of entries, we want to create
a fake global label at that point to end the scope.

Merlin 32 won't let you write " LDA #',' ".  For some reason the
comma causes an error.  IGenerator now has a "tweak operand format"
interface that lets us fix that.

6df874c559 Minor changes to local variable tables
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.

I was using the plain names, but when you've got symbols like

obvious where something came from.  Now all monitor symbols begin
with MON_, and Applesoft symbols begin with BAS_.

The Amper-fdraw example ended up with a few broken symbol refs,
because it was created before project/platform symbols followed the
"nearby" rules, and was explicitly naming LINNUM and AMPERV.  I
switched the operands to default, and they now auto-format correctly.

I added a few more entries to Applesoft while I was at it.

d542a809f8 Implement local variables for ACME
Unlike 64tass and Merlin, which allow you to redefine symbols, ACME
uses "zones" that provide scope for local variables.  This means
that, at the point of a local variable table definition, we have to
start a new zone and output the full set of active symbols, not just
the newly-defined ones.  (If you set the "clear previous" flag in
the LvTable there's no difference.)

We could do a bit better by only outputting the symbols that are
actually used within the zone, similar to what we do for global
project/platform symbols, but that's a bunch of work for questionable
benefit.

After thrashing around a bit, I had to choose between making the
uniquifier more complicated, or making de-duplication a separate
step.  Since I don't really expect duplicates to be a thing, I went
with the latter.

Updated the regression test.

963b351a52 Add 2019-local-variables test
This hits most of the edge cases, but doesn't exercise the two
duplicate name situations (var name same as user label, var name
same as project/platform symbol).

Also, fixed a bug in the EditDefSymbol uniqueness check where it
was comparing a symbol to itself.

6a2532588b Local variables mostly work
Variables are now handled properly end-to-end, except for label
uniquification.  So cc65 and ACME can't yet handle a file that

0ed1547e79 Set Anattrib DataDescriptor for local variable references
We now generate FormatDescriptors with WeakSymbolRefs for direct
page references that match variable table entries.

LocalVariableTable got a rewrite.  We need to be unique in both
name and address, but for the address we have to take the width into
account as well.  We also want to sort the display by address
rather than name.  (Some people might want it sorted by name, but
we can worry about that some other time.)

Updated the DefSymbol editor to require value uniqueness.  Note
addresses and constants exist in separate namespaces.

The various symbols are added to the SymbolTable so that uniqueness
checks work correctly.  This also allows the operand generation to
appear to work, but it doesn't yet handle redefinition of symbols.

0eeb36f59a Add LocalVariableTable list to project
This involved adding a list to the DisasmProject, creating a new
UndoableChange type, and writing the project file serialization
code.  While doing the latter I realized that the new Width field
was redundant with the FormatDescriptor Length field, and removed it.

I added a placeholder line type, but we're not yet showing the
table in the display list.  (To edit the tables you just have to
know where they are.)

32d1147eec Improve multi-encoding output in 64tass
Previously, we used the default character encoding from the project
properties to determine how strings and character constants in the
entire source file should be encoded.  Now we switch between
encodings as needed.  The default character encoding is no longer
relevant.

High ASCII is now an actual encoding, rather than acting like ASCII
that sometimes doesn't work.  Because we can do high ASCII character
operands with "| $80", we don't output a .enc to switch from ASCII
to high ASCII unless we need to generate a string.  (If we're
already in high ASCII mode, the "| $80" isn't required but won't
hurt anything.)

We now do a scan up front to see if ASCII or high ASCII is needed,
and only output the .cdefs for the encodings that are actually used.

The only gap in the matrix is high ASCII DCI strings -- the ".shift"
pseudo-op rejects text if the string doesn't start with the high
bit clear.

38d3adbb08 PETSCII does DCI
I didn't think it made sense, but I found something that used it,
so apparently it's a thing.  This updates the operand editor to
let you choose PETSCII+DCI, and updates the assemblers to handle
it correctly (really just 64tass, since the others either don't
have a DCI directive or don't deal with PETSCII at all).

Changed the char-encoding sample from "bad dcI" to "pet dcI", and
updated the documentation.

149e763821 Change the way ASCII is handled for 64tass
The documentation for 64tass says you're required to pass "--ascii"
when the source file is ASCII (as opposed to PETSCII).  We were
ignoring this, but it turns out that everything works a bit better
if we don't.

So we now pass "--ascii" on the command line, and add a two-line
character encoding definition to every file that is generated with
ASCII as the default encoding.  The sg_petscii and sg_screen
encodings go away, as PETSCII is now the default, and we can use the
built-in "screen" encoding.

f87ac20f32 Add a string operand cache
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.

4902b89cf8 Various improvements
The PseudoOpNames class is increasingly being used in situations
where mutability is undesirable.  This change makes instances
immutable, eliminating the Copy() method and adding a constructor
that takes a Dictionary.  The serialization code now operates on a
Dictionary instead of the class properties, but the JSON encoding is
identical, so this doesn't invalidate app settings file data.

Added an equality test to PseudoOpNames.  In LineListGen, don't
reset the line list if the names haven't actually changed.

Use a table lookup for C64 character conversions.  I figure that
should be faster than multiple conditionals on a modern x64 system.

Fixed a 64tass generator issue where we tried to query project
properties in a call that might not have a project available
(specifically, getting FormatConfig values out of the generator for
use in the "quick set" buttons for Display Format).

Fixed a regression test harness issue where, if the assembler reported
success but didn't actually generate output, an exception would be
thrown that halted the tests.

Increased the width of text entry fields on the Pseudo-Op tab of app
settings.  The previous 8-character limit wasn't wide enough to hold
ACME's "!pseudopc".  Also, use TrimEnd() to remove trailing spaces
(leading spaces are still allowed).

In the last couple of months, Win10 started stalling for a fraction
of a second when executing assemblers.  It doesn't do this every
time; mostly it happens if it has been a while since the assembler
was run.  My guess is this has to do with changes to the built-in
malware scanner.  Whatever the case, we now change the mouse pointer
to a wait cursor while updating the assembler version cache.

479be1a58e Add 2016-char-encoding-a and variations
All tests use the same data file and nearly the same project file.
The only difference is the default text encoding property setting.
For "-a" it's ASCII, for "-p" it's PETSCII, for "-s" it's C64 screen
code.  Right now this only affects the code generated for 64tass.

The test itself is a collection of strings and characters in the
supported character encodings.  How these are handled varies
significantly between assemblers.

81029afae5 Generate C64 encodings in 64tass output
The 64tass generator now uses the "default text encoding" project

encoding table is generated at the top of the output file.

Both dialogs got a couple extra radio buttons for selection of

that lets you specify how it scans for viable strings.

Various string scanning methods were made more generic.  This got a
little strange with auto-detection of low/high ASCII, but that was
mostly a matter of keeping the previous code around as a special
case.

8fd469b81f Correctly handle delimiters in character operands
We weren't checking to see if character operands matched their
delimiters, so bad code like "LDA #'''" was being generated.

There wasn't a test for this in 2006-operand-formats, so the test
has been updated with single and double quotes in low and high ASCII.

beb1024550 Define and use "delimiter sets"
A delimiter definition is four strings (prefix, open, close, suffix)
that are concatenated with the character or string data to form an
operand.  A delimiter set is a collection of delimiter definitions,
with separate entries for each character encoding.

This is a convenient way to configure Formatter objects, import and
export data from the app settings file, and manage the UI needed to
allow the user to customize how things look.

The full set of options didn't fit on the first app settings tab, so
there's now a separate tab just for specifying character and string
delimiters.  (This might be overkill, but there are various plausible
scenarios that make use of it.)

The delimiters for on-screen display of strings can now be
configured.

5889f45737 Replace on-screen string operand formatting
The previous functions just grabbed 62 characters and slapped quotes
on the ends, but that doesn't work if we want to show strings with
embedded control characters.  This change replaces the simple
formatter with the one used to generate assembly source code.  This
increases the cost of refreshing the display list, so a cache will
need to be added in a future change.

Converters for C64 PETSCII and C64 Screen Code have been defined.
The results of changing the auto-scan encoding can now be viewed.

The string operand formatter was using a single delimiter, but for
the on-screen version we want open-quote and close-quote, and might
want to identify some encodings with a prefix.  The formatter now
takes a class that defines the various parts.  (It might be worth
replacing the delimiter patterns recently added for single-character
operands with this, so we don't have two mechanisms for very nearly
the same thing.)

While working on this change I remembered why there were two kinds
of "reverse" in the old Merlin 32 string operand generator: what you
want for assembly code is different from what you want on screen.
The ReverseMode enum has been resurrected.

f3c28406a5 Add multiple encoding support to uncategorized data analyzer
The code that searches for character strings in uncategorized data
now recognizes the C64 encodings when selected in the project
properties.

The new code avoids some redundant comparisons when runs of
printable characters are found.  I suspect the new implementation
loses on overall performance because we're now calling through
delegates instead of testing characters directly, but I haven't
tested for that.

d5b53a0795 Add combo box for default text scan mode

f33cd7d8a6 Replace character operand output method
The previous code output a character in single-quotes if it was
standard ASCII, double-quotes if high ASCII, or hex if it was neither
of those.  If a flag was set, high ASCII would also be output as
hex.

The new system takes the character value and an encoding identifier.
The identifier selects the character converter and delimiter
pattern, and puts the two together to generate the operand.

While doing this I realized that I could trivially support high
ASCII character arguments in all assemblers by setting the delimiter
pattern to "'#' | $80".

In FormatDescriptor, I had previously renamed the "Ascii" sub-type
"LowAscii" so it wouldn't be confused, but I dislike filling the
project file with "LowAscii" when "Ascii" is more accurate and less
confusing.  So I switched it back, and we now check the project
file version number when deciding what to do with an ASCII item.
The CharEncoding tests/converters were also renamed.

Moved the default delimiter patterns to the string table.

Widened the delimiter pattern input fields slightly.  Added a read-
only TextBox with assorted non-typewriter quotes and things so
people have something to copy text from.

068b3a44c7 Remove "high" versions of string pseudo-ops
High ASCII and other encodings will be noted in the operand field,
not the opcode, so we no longer need these.

This removes the six input fields from the Pseudo-Op tab of app
settings.  Values were stored as a serialized class in settings,
which generally works correctly as far as forward/backward
compatibility goes, so no worries there.

This also adds four "delimiter pattern" fields to the Code View tab,
allowing the user to customize how encoded strings are marked up
for the code list.  The values aren't actually used yet.

Also, fixed an issue where changes to text fields on the Pseudo-Op
tab weren't raising the dirty flag.

15d26c9ebd Don't do plugin interface checks during code analysis
The plugin objects are MarshalByRefObject stubs, which means they
don't actually implement the interfaces we're checking for.  There's
some additional overhead to do the interface check.  We can avoid
it by doing the interface queries during initialization, and just
checking some bit flags later on.

Also, in the extension script info window, show a list of
implemented interfaces.

975b62db6b Treat low and high ASCII as two distinct formats
We've been treating ASCII strings and instruction/data operands as
ambiguous, resolving low vs. high when generating output for the
display or assembler.  This change splits it into two separate
formats, simplifying output generation.

The UI will continue to treat low/high ASCII as as single thing,
selecting the format appropriately based on the data.  There's no
reason to have two radio buttons that are never both enabled.

The data operand string functions need some additional work, but
that overlaps substantially with the upcoming PETSCII changes, so
for now all strings set by the data operand editor are low ASCII.

The file format has changed again, but since there hasn't been a
release since the previous change, I'm leaving the file format
at v2.  Code has been added to resolve the ASCII mode when loading
a v1 project file.

This removes some complexity from the assembly code generators.

dae76d9b45 Rework string operand formatting
This generalizes the string pseudo-operand formatter, moving it into
the Asm65 library.  The assembly source generators have been updated
to use it.  This makes the individual generators simpler, and by
virtue of avoiding "test runs" should make them slightly faster.

This also introduces byte-to-character converters, though we're
currently still only supporting low/high ASCII.

835c1c7fe2 Reverse position on '#' in block move operands
During a discussion with the cc65 developers, I became convinced that
generating "MVN $01,$02" is wrong, and "MVN #$01,#$02" is correct.
64tass, cc65, and Merlin 32 all accept this syntax; only ACME does
not.  Operands without a leading '#' should be treated as 24-bit
values, and have the bank byte extracted.

This change updates the on-screen display and assembled output to
include the '#'.  The ACME generator uses a Quirk to suppress the
hash mark.  (It doesn't currently accept values larger than 8 bits,
so there's no ambiguity.)

0d0854bda7 Change the way string formats are defined
We used to use type="String", with the sub-type indicating whether
the string was null-terminated, prefixed with a length, or whatever.
This didn't leave much room for specifying a character encoding,
which is orthogonal to the sub-type.

What we actually want is to have the type specify the string type,
and then have the sub-type determine the character encoding.  These
sub-types can also be used with the Numeric type to specify the
encoding of character operands.

This change updates the enum definitions and the various bits of
code that use them, but does not add any code for working with
non-ASCII character encodings.

The project file version number was incremented to 2, since the new
FormatDescriptor serialization is mildly incompatible with the old.
(Won't explode, but it'll post a complaint and ignore the stuff
it doesn't recognize.)

While I was at it, I finished removing DciReverse.  It's still part
of the 2005-string-types regression test, which currently fails
because the generated source doesn't match.

98914e9f80 Treat BRK as a 1-byte instruction
The 65816 definition makes it a two-byte instruction, like COP.  On
the 6502 it acted like a two-byte instruction, but in practice very
few assemblers treat it that way.  Very few humans, for that matter.
So it's now treated as a single byte instruction, with the following
byte encoded as a data value.

0616e4e4a4 Define interfaces for inline call handlers and BRK
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.

02f6e884d7 Fix startup issues
- 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.

9e525d1428 Populate symbol table, with filtering and sorting
The filtering uses the DataGrid View filtering mechanism.  The
built-in sorting only operates on a single column, and we really
want a secondary sort on label when the type is used as the key,
so we provide a custom sort method.

97a372a884 Add selectable auto-label styles
SourceGen creates "auto" labels when it finds a reference to an
address that doesn't have a label associated with it.  The label for
address $1234 would be "L1234".  This change allows the project to
specify alternative label naming conventions, annotating them with
information from the cross-reference data.  For example, a subroutine
entry point (i.e. the target of a JSR) would be "S_1234".  (The
underscore was added to avoid confusion when an annotation letter
is the same as a hex digit.)

Also, tweaked the way the preferred clipboard line format is stored
in the settings file (was an integer, now an enumeration string).

47b1363738 Add more detail to cross references

source is doing a read, write, read-modify-write, branch, subroutine
call, is just referencing the address, or is part of the data.

84eceee085 Note removal of cc65 limitation 2018-11-18 15:20:12 -08:00
Andy McFadden
2065f4ef9e Attempt to generate segment names for cc65
This worked, sort of.  The problem is that SourceGen will revert to
hex output in certain situations, such as a broken symbolic
reference.  There happens to be one in the ZIPPY example, and it's
on a relative branch.

The goal with the segment stuff is to allow cc65 to treat the
source as relocatable code.  In that context, a relative branch to
an absolute address doesn't make any sense, so the assembler reports
a range error.

We don't currently have a mechanism that guarantees no references
are broken (and no affordance for finding them), so we can't make
this mode the default yet.

Instead, we continue to use the generic config, but generate the
correct set of lines as comments.

17f0faa845 Add linker config scripts to cc65 generator output
The system configuration you get with "-t none" works for smaller
files but fails for larger ones.  This updates the generator to
produce a source file and linker script pair.  (I kinda saw this
one coming -- it's why the gen/asm dialog has a combo box for the
file preview -- so it didn't require that much work.)

This currently generates a fixed script for a generic system with
64KiB of RAM, using .ORGs to set the addresses as before.

With this change, assembling a file with 65536 NOPs succeeds.

2f74fce80b Expand set of things that work with double-click on opcode
If you double-click on the opcode of "JSR label", the code view
selection jumps to the label.  This now works for partial operands,
e.g. "LDA #<label".

Some changes to the find-label-offset code affected the cc65 "is it
a forward reference to a direct-page label" logic.  The regression
test now correctly identifies an instruction that refers to itself
as not being a forward reference.

a88c746419 Work around cc65 single-pass behavior
The cc65 assembler runs in a single pass, which means forward
address references default to 16 bits.  For zero-page references
we have to add an explicit width disambiguator.  (This is an
unusual situation that only occurs if you have a zero-page .ORG
in the file after code that references it.)

With this change, 2014-label-dp passes, and no other regression
tests were affected.

This adds a null check on the dfd argument in FormatDataOp() to see

wrong.  Hopefully this will allow capture of a project that exhibits
the problem.

da91f86043 Get 64tass expressions working
We now insert parenthesis as needed.  This can cause problems in
some situations, so we always prefix parenthetical expressions with
"0+", which looks goofy and is unnecessary for immediate operands.
But it does generate working source code.

Renamed the "simple" expression mode to "common", as it's not
particularly simple but is what you'd expect most assemblers to do.
(OTOH, life has been full of surprises.)

61914c8f79 Progress toward 64tass expression support
Gave cc65 its own expression generator, as the precedence table seems
atypical if not unique.  Configured 64tass to use the "simple"
expression mode.

Added some operations on a 32-bit constant to 2007-labels-and-symbols
to exercise the current worst-case expression (shift + AND + add).
Tweaked the Merlin expression generator to handle it.

f7e5cf2f45 Progress toward 64tass support
Most tests pass, but 2007-labels-and-symbols fails because the
expressions recognized by 64tass don't match up with either of the
other assemblers.

This is currently using a workaround for the local label syntax.
64tass uses '_' as the prefix, which is unfortunate since SourceGen
explicitly allowed underscores in labels.  (So does 64tass for that
matter, but it treats labels specially when the '_' comes first.)
We will need to rename any non-local user labels that start with '_'.

80da6cc1df Replace symbol used to indicate embedded instructions
We were using \u23e9, BLACK RIGHT-POINTING DOUBLE TRIANGLE, but
neither Win7 SP1 nor Linux was able to display the glyph.  It also
gets all puffy in web browsers.  We now use \u25bc, BLACK
DOWN-POINTING TRIANGLE, which seems to work everywhere.  It also
feels more appropriate, because it appears next to the "containing"
opcode, with the embedded instruction appearing on the following
line.

4f9af30455 Progress toward new assembler configuration
Rather than have each assembler get its own app config string for
the cross-assembler executable, we now have a collection of per-
assembler config items, of which the executable path name is one
member.  The Asm Config tab has an auto-generated pop-up to select
the assembler.

The per-assembler settings block is serialized with the rather
unpleasant JSON-in-JSON approach, but nobody should have to look
at it.

This also adds assembler-specific column widths to the settings
dialog, though they aren't actually used yet.

f81c534d25 Merge Gen* and Asm* source files
Each supported assembler has an IGenerator interface and an
IAssembler interface.  They're still two separate classes, but now
both are implemented in the same source file.  (They'll probably
stay separate classes, since the two have little interaction.)

I'm keeping the "Asm*" filename.  Seems the more natural fit.

Also, changed AssemblerInfo to try to get all assembler-specific
stuff into a single table.
