If you edit an existing symbol, the "is the label unique" test will
always false-positive match itself, so we have to explicitly handle
that case. Dialogs like Edit Instruction Operand make things a bit
more complicated because they don't flush results to the symbol
table immediately, which means the symbol we pass into the Edit Def
Symbol dialog to edit isn't necessarily the one we need to exclude
from the label uniqueness test.
The dialog was using the initial value as both "original" and
"initial", which caused some issues. We now pass both values in.
Also, removed some dead code identified by VS.
The recent tweaks to improve operand editing broke a common case
when creating a project symbol.
Also, tweaked the operand edit case a little more, for the case where
the operand's symbol was entered manually.
Minor change to solution. Removed CodeLab project stub, which was
still targeting .NET Framework 4.6.1.
The other projects with WPF code target 4.6.2, and I haven't updated
them to 4.8 out of a fear that it might make 6502bench harder to
install on older systems. The down side is that it requires an
extra "dev pack" download to build the source code. 4.8 is the end
of the line for .NET Framework, so at some point we should make that
the official target.
If a symbol is marked as "exported", it is added to the symbol table
generated at the end of the HTML output. If the symbol identifies a
non-addressable location, we need to show that.
Also, added a header row.
Double-clicking on an entry in the symbols window is supposed to take
you to the place where that symbol is defined. This worked for code
labels but not for project/platform symbols. We now jump to the
appropriate EQU statement, if one exists.
The instruction operand editor has a shortcut button for editing a
project symbol. Attempting to change the comment field twice
without closing the operand editor in between would result in a
complaint about duplicate symbol names.
The setting determines whether bulk data is displayed as an unbroken
string of hex digits, or as "$xx,$xx,...". The latter is easier to
read and should be the default.
One place in the code did consider it to be the default, so if the
config file didn't have a value for the setting, the settings UI would
incorrectly show it as enabled.
The existing API was better suited to direct color than indexed
color. The NES visualizer was using a slightly silly hack to avoid
duplicate colors; this has been removed.
The ListView style was using "Stretch" for TextBoxes in the code list,
which caused the background of the entire address / label / operand
field to be drawn in the highlight color, rather than just the area
covered by the text. This is fine for address and label, but it just
felt weird for the operand field because that tends to be very wide
(to accommodate strings, bulk hex data, etc).
There doesn't seem to be a way to specify HorizontalContentAlignment
per-column in WPF. (Note this is different from HorizontalAlignment,
which *is* is a per-column property.)
This changes the style to use HorizontalContentAlignment=Left, so
the highlight just covers the text. The only time this causes a
functional change is when you highlight an operand for a line that
doesn't have a label, because instead of highlighting an empty
rectangle you now see nothing at all. (The address field is still
highlighted though.)
When a code or data line is selected in the code list, if the operand
is an address inside the file, we highlight the address and label.
It's also useful to highlight the other way: when a code or data line
is selected, find all lines whose operands reference it, and highlight
the operand field.
This is a little trickier because there can be multiple references,
but all of the information we need is in the cross-reference table.
The tutorial was creating a new address region at +000002 without
removing the previous one, which leaves the 16-bit file load address
sitting at $1000 when it should be non-addressable. The text now
shows the correct procedure. Some screen shots had to be recaptured
to show the greyed-out address field.
This doesn't change anything meaningful about the disassembly -- the
PRG optimization hides the region start/end markers either way -- but
it's more correct this way, and it's an opportunity to introduce
the use of non-addressable regions for file headers.
Biggest changes were to the address region handling in Tutorial1
and the use of StdInline.cs for the inline strings in Tutorial4.
Also, fixed the off-by-one error in Tutorial1.
The code that sets and removes analyzer tags allows you to select a
mix of lines. If the mix included the header comment, the negative
file offset would cause a crash.
If an end-of-line comment ended with '\', the code that "prettifies"
the JSON output would get confused, and would start inserting \r\n
after commas inside comment strings. This didn't corrupt the project
files, but it did make them look funny, and required manual cleanup.
Added a sample. This won't catch regressions of this particular
problem because it only happens when you save the file, but if
nothing else it'll act as documentation.
End-of-line comments have a couple of guidelines: keep it short, and
don't use non-ASCII characters. Violating these isn't an error, so
we should be making the text blue rather than red.
The DVG format, used for vector games like Asteroids, is the
predecessor to the AVG graphics used in games like Battlezone.
Also, added some extended error checks on wireframe vertices.
Also, minor edits to the README and daily tips.
The implementation was mapping labels to addresses, then formatting
inline data at the matching address. This may be incorrect when there
are multiple sections of the file mapped to the same address. The
correct approach is to record the offsets of the matching labels, and
then do an address-to-offset translation for each JSR.
Also, show a note in the Info window when a JSR has been marked
no-continue by an extension script.
Also, updated Daily Tips.
If you change the selection by double-clicking in one of the side
windows (References, Notes, Symbols, Messages) and then attempt
to navigate with the arrow keys, the program will appear to hang
briefly, then jump to the start or end of the project and shift the
window focus to something else (like the Help menu in the menu bar).
For reasons I don't fully understand, the behavior is fixed by
removing unnecessary calls to codeListView.Focus(). The calls were
intended to shift input focus to the main ListView, but they're no
longer necessary, and appear to upset WPF.
(issue #113)
We allow empty lines and lines that begin with ';' in .sym65. Lines
with nothing but whitespace, or comments with leading whitespace,
caused a warning. It can be aesthetically nice to line up the start
of comments, and lines with pointless whitespace aren't problematic,
so we now allow these without complaint.
Added some samples to the 20170-external-symbols data file. No
change to the test output.
It's useful for extension scripts to be able to get the file offset
of symbols in non-addressable regions. One example of this is CHR
ROM data for an NES cartridge. However, we were getting the offset
by doing an address-to-offset mapping on the plugin side, which by
definition doesn't work for non-addressable memory.
So we now add the offset to PlSymbol objects for user labels and
address region pre-labels. The NES visualizer has been updated to
use the new field.
Also, fixed a bogus complaint about bank overruns for non-addressable
regions.
Altered the address region edit UI a little to improve clarity.
Also, close the hex dump viewer window when Escape is hit. (The
tool windows don't have "cancel" buttons, so the key has to be
handled explicitly.)
The ACME assembler gets upset if you use "not" as a label. We now
avoid doing so, using a generalized implementation of the opcode
mnemonic rename code. (Issue #112.)
Renamed a label to "not" in the 20081-label-localizer test.
Fixed a crash when the listing is refreshed while a .adrend line is
the only thing selected.
Fixed .adrend lines being spammed if the last thing before it is a
multi-byte item, and you edit a comment / note / label on that line.
Harmless, but weird.
Also, added keyboard shortcuts in DefSymbol editor, so you can change
from address to constant with Alt+C.
If you put a value in the "symbol" field of an instruction with an
address operand, you're establishing a symbolic reference to a label
that may be at a different address than the numeric value of the
operand. But if you then hit the "edit label" button, you'll edit
the label at the *numeric* reference address, which can be confusing.
We now disable the create/edit label button when the format has been
set to "symbol".
The button is just a short-cut, so disabling it doesn't prevent the
user from doing anything.
