8b20021c4d Show visualization bitmap dimensions
The preview window scales freely, so it's hard to know how big the
actual pixels are.

071adb8e95 Two changes to "dense hex" bulk data formatting
(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.)

e82678126f Various minor tweaks
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.)

5635a1e33a Add Atari 2600 sprite/playfield visualizer
First swing at a visualizer for Atari 2600 sprites and playfields.
Won't necessarily present an accurate view of what is displayed on
screen, but should provide a reasonable shape for data stored in
the obvious way.

The Adventure playfields looked squashed, so I added a simple row
duplication value.

Also, minor improvements to visualizers generally:
- Throw an exception, rather than an Assert, in VisBitmap8 when the
  arguments are bad.
- Show the exception in the Visualization Edit dialog.
- If generation fails and we don't have an error message, show a
  generic "stuff be broke" string.
- Set focus on OK button in Visualization Set Edit after editing,
  so you can hit Enter twice after renaming a tag.

1cdb31de32 Visualizer improvements
Various changes:
- Generally treat visualization sets like long comments and notes
  when it comes to defining data region boundaries.  (We were doing
  this for selections; now we're also doing it for format-as-word
  and in the data analyzer when scanning for strings/fill.)
- Clear the visualization cache when the address map is altered.
  This is necessary for visualizers that dereference addresses.
- Read the Apple II screen image from a series of addresses rather
  than a series of offsets.  This allows it to work when the image
  is contiguous in memory but split into chunks in the file.
- Put 1 pixel of padding around the images in the main code list,
  so they don't blend into the background.
- Remember the last visualizer used, so we can re-use it the next
  time the user selects "new".
- Move min-size hack from Loaded to ContentRendered, as it apparently
  spoils CenterOwner placement.

4d079c8d14 Label rework, part 1
This adds the concept of label annotations.  The primary driver of
the feature is the desire to note that sometimes you know what a
thing is, but sometimes you're just taking an educated guess.
Instead of writing "high_score_maybe", you can now write "high_score?",
which is more compact and consistent.  The annotations are stripped
off when generating source code, making them similar to Notes.

I also created a "Generated" annotation for the labels that are
synthesized by the address table formatter, but don't modify the
label for them, because there's not much need to remind the user
that "T1234" was generated by algorithm.

This also lays some of the groundwork for non-unique labels.

b4213de4c0 Add "Go to Last Change" feature
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.

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.

70353c82e1 Limit value range of project address symbols
Project symbol address values are now limited to positive 24-bit

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.)

463fbff368 Show load address in Edit Address dialog
Sometimes code relocates a few bits of itself but not others.  We
don't currently have a way to say, "go back to where we would have
been".  As a cheap alternative, we now show the "load address", i.e.
where we'd be if there were no address map entries after the first.

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.

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.

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.

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.

See also issue #44.

b8e11215fa Add separate button for adding symbols+scripts from project
The "add platform symbol file" and "add extension script" buttons
create a file dialog with the initial directory set to the
RuntimeData directory inside the SourceGen installation directory.
This is great if you're trying to add a file from the platform
definitions, but annoying if you're trying to add it from the
project directory.

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.

28eafef27c Expand the set of things SetInlineDataFormat accepts
Extension scripts (a/k/a "plugins") can now apply any data format
supported by FormatDescriptor to inline data.  In particular, it can

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.

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.

Increased the maximum width of a variable from 4 to 8.  (This is
entirely arbitrary.)

44c140a8d0 Add "Copy to Operand" button to instruction operand editor
It's possible to define multiple project symbols with the same
address.  The way to resolve the ambiguity is to explicitly
reference the desired symbol from the operand.  This was the
default behavior of the "create project symbol" shortcut in the
previous version.

It's rarely necessary, and it can get ugly if you rename a project
symbol, because we don't refactor operands in that case.

Also, removed "include symbol table" from export dialog.  You can
exclude the table by removing it from the template, which right
now  you'd need to do anyway to get rid of the H2 header and other
framing.  To make this work correctly as an option we'd need to
parse the "div" in the template file and strip the whole section,
or split the template into multiple parts that get included as
needed.  Not worth doing the work until we're sure it matters.

Also, updated the code list double-click handler so that, if you
double-click on the opcode of an instruction that uses a local
variable reference, the selection and view will jump to the place
where that variable was defined.

Also, tweaked the way the References window refers to references
to an address that didn't use a symbol at that address.  Updated
the explanation in the manual, which was a bit confusing.

Also, fixed some odds and ends in the manual.

The code that checked to see if a data target was inside a data

It was also failing to stop when it should, wasting time.

The anattrib validation method has code that avoids a false-positive
on certain complex embedded instruction arrangements.  This was also

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.

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.

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.)

There's no easy way to make non-zero-bank 65816 code work, so I'm

renders tests 2007 and 2009 useless, so I'm hesitant to claim that

- 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.

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).

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 '_'.

neither Win7 SP1 nor Linux was able to display the glyph.  It also

feels more appropriate, because it appears next to the "containing"

line.

If PTR is defined as an external symbol, we were automatically

address is preceded by a JMP opcode.

9be99a7cac Make hint application less annoying
Two changes:
(1) Code and data hints are now only applied to the first byte on

    and hint removal work as before.
(2) Added a menu item (with Ctrl+D as shortcut) to toggle the state
    of the uncategorized data analyzer.  This makes it easy to turn
    off the feature that put the code into a string in the first
    place.
