When editing local variables, the data grid generally has the input
focus, so hitting Enter doesn't close the dialog. Rather than play
games with the focus, just take Ctrl+Enter as a shortcut to close
the dialog (same as notes and long comments).
(I found myself hitting Ctrl+Enter automatically, and being annoyed
when it didn't work, so I figured I'd make it official.)
Continue development of non-unique labels. The actual labels are
still unique, because we append a uniquifier tag, which gets added
and removed behind the scenes. We're currently using the six-digit
hex file offset because this is only used for internal address
symbols.
The label editor and most of the formatters have been updated. We
can't yet assemble code that includes non-unique labels, but older
stuff hasn't been broken.
This removes the "disable label localization" property, since that's
fundamentally incompatible with what we're doing, and adds a non-
unique label prefix setting so you can put '@' or ':' in front of
your should-be-local labels.
Also, fixed a field name typo.
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.
Not a huge improvement, but things are slightly more organized, and
there's a splash of color in the form of a border around the text
describing the format of code and data lines.
Added an "IsConstant" property to Symbol.
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.
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.
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.)
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).
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.
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.)
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.
