We weren't escaping '<', '>', and '&', which caused browsers to get
very confused. Browsers seem to prefer <PRE> to <CODE> for long
blocks of text, so switch to that.
Also, added support for putting long labels on their own lines in
the HTML output.
Also, fixed some unescaped angle brackets in the manual.
Also, tweaked the edit instruction operand a bit more.
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.
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.
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).
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).
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.
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.
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.
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.
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
punting and just generating a whole-file hex dump for those. This
renders tests 2007 and 2009 useless, so I'm hesitant to claim that
ACME support is fully functional.
- 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.
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).
In the cross-reference table we now indicate whether the reference
source is doing a read, write, read-modify-write, branch, subroutine
call, is just referencing the address, or is part of the data.
In the data operand edit section, walk through selecting a single
byte vs. multiple bytes when you want to set a multi-byte format.
(inspired by issue #41)
The 2014-label-dp test now passes. Prior regression tests are
unaffected.
Also, renamed an IGenerator interface to more accurately reflect
its role.
(issue #37)
Before you could choose between Merlin-style and generic. Now
there's a combo box that lets you choose Merlin, cc65, or
"common", the latter being used for 64tass.
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.
(issue #16)
Correctly handle pre-existing underscores and avoidance of
"reserved" labels.
Also, add more underscores to 2012-label-localizer to exercise
the code.
(issue #16)
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 '_'.
(issue #16)
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.
Once upon a time, symbol files and extension scripts could only be
defined in the RuntimeData directory, so having the documentation
there made sense. Since both of these things can now be defined in
project directories, the documentation belongs in the manual.
(issue #27)
If PTR is defined as an external symbol, we were automatically
symbol-ifying PTR+1. Now we also symbolify PTR+2. This helps with
24-bit pointers on the 65816, and 16-bit "jump vectors", where the
address is preceded by a JMP opcode.
Removed the "AMPERV_" symbol I added to make the tutorial look
right.
The instruction operand editor and data operand editor are very
different, but there's no need to impose that distinction on the
user. They want to edit the operand either way. We now provide a
single "edit operand" menu item, and open the appropriate dialog
based on what they have selected.
This uses Ctrl+O as the keyboard shortcut, stealing it from
File > Open.
(issue #11)
Two changes:
(1) Code and data hints are now only applied to the first byte on
each selected line. This allows you to slap a code hint on a
string without lighting up the whole string. Inline-data hints
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.
Don't enable OK unless at least one address is valid.
Don't apply code hints unless asked.
Rename a couple of things for clarity.
Add documentation to manual.
(issue #10)
