bb23bf82d1 Instruction operand editor rework, part 4 (of 4)
Updated the manual, and changed tutorial #2 to use local variables
for pointers.

If the symbol text box isn't empty, use the string as the initial
value for the Label when creating a new project property.

Fixed a crash when editing a project property.

e8ae534879 Instruction operand editor rework, part 2
Implemented local variable editing.  Operands that have a local
variable reference, or are eligible to have one, can now be edited
directly from the instruction operand edit dialog.

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.

Also, fixed a nasty infinite recursion bug (issue #47).

2633720c82 Instruction operand editor rework, part 1
Rearrange the UI elements, and convert the code-behind to a more
XAML-style form.  The basic stuff works, but the old "shortcut"
system is still in the process of being replaced.

ee6e5d7fb6 Fix a couple of obscure bugs
The code that checked to see if a data target was inside a data
operand wasn't going all the way back to the start of the file.
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
preventing it from seeing a transition from a data area to the
middle of an instruction (caused by issue #45).

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.

c698048001 Handle variable labels that are duplicates of non-variables
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.

b65f75437d Make local variable prefix configurable for display
It's kind of handy to have variable labels tagged.  This makes it

leave it blank.

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
redefines a local variable.

This required a bunch of plumbing, but I think it came out okay.

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.

c4c67757c0 Show variable tables in line list
Multi-line item, with one .eq line per variable definition.  Add
one header line if "clear previous" is set.

Also, limit variable values to 0-255 in the editor.  This is
somewhat arbitrary, but I think a focus on DP is useful.

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.)

1cc9d2bd70 Update editors to work with local variables
The table editor is now editing the table, and the DefSymbol editor
now asks for the Width data when editing a local var.

This also moves EditDefSymbol closer to proper WPF style, with
bound properties for the input fields.

No changes yet to serialization or analysis.

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
property to determine how readable text should be encoded.  For
example, if the property is set to PETSCII, an ASCII-to-PETSCII
encoding table is generated at the top of the output file.

7bbe5692bd Add C64 encodings to instruction and data operand editors
Both dialogs got a couple extra radio buttons for selection of
single character operands.  The data operand editor got a combo box
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.

Made C64 Screen Code DCI strings a thing that works.

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.
