By default, implicit acc operands are shown, e.g. "LSR A" rather
than just "LSR". I like showing operands for instructions that
have multiple address modes.
Not everyone agrees, so now it's a setting. They're shown by default,
but enabling the option will strip them on-screen, in generated
assembly, and in the instruction chart.
They are always omitted for ACME output, which doesn't allow them.

Added the recovery file check when a project is opened, and the GUI
elements for choosing which file to use.
If a recovery file exists but can't be opened, presumably because it's
open by another process, offer to open the project read-only. (This
is a generally good idea, but we don't hold the project file open
in normal usage, so it only works when auto-save is enabled.)
After making a choice, auto-save is disabled until the first manual
save.
One thing we don't do: if we find a recovery file, but auto-save is
disabled, the recovery file won't be deleted after the user makes a
choice. This might be a feature.
Updated documentation.

The pop-up that lets you choose which assembler to set configuration
options for looked like it let you choose an assembler generally.
Changed some wording and visuals for better clarity.
Added a "format help" button to the long comment edit window. This
brings up a quick summary of the format tags in a modal dialog.
Updated documentation and tutorial.
While it's okay to use ';', the classic Merlin editor will treat it
as an end-of-line comment and shove the entire thing off to the right
side of the screen.
This adds a configuration item to the app settings, with a default
value of ';'.
This adds a new data format option, "binary include", that takes a
filename operand. When assembly sources are generated, the section
of file is replaced with an appropriate pseudo-op, and binary files
are generated that hold the file contents. This is a convenient way
to remove large binary blobs, such as music or sound samples, that
aren't useful to have in text form in the sources.
Partial pathnames are allowed, so you can output a sound blob to
"sounds/blather.bin". For safety reasons, we don't allow the files
to be created above the project directory, and existing files will
only be overwritten if they have a matching length (so you don't
accidentally stomp on your project file).
The files are not currently shown in the GenAsm dialog, which lets
you see a preview of the generated sources. The hex dump tool
can do this for the (presumably rare) situations where it's useful.
A new regression test, 20300-binary-include, has been added. The
pseudo-op name can be overridden on-screen in the settings.
We don't currently do anything new for text/HTML exports. It might
be useful to generate an optional appendix with a hex dump of the
excised sections.
(issue #144)
Note that address region isolation doesn't prevent explicit label
references from working (add update the test to prove it).
Added a note about pre-label xrefs.
If an address resolves to a user label in an isolated region, we
don't want to use it. However, we still want to try to match it
to a project/platform symbol.
For example, suppose the isolated code wants to reference address
$1C00, which is a memory-mapped I/O location in one area, but a
regular bunch of code in the other. We don't want it to map to
the regular code, but we do want it to resolve to our table of
platform I/O addresses.
We now handle this correctly. The regression test has been updated
to check this. The current implementation does a linear scan through
the symbol table, but I'm hoping this is not a common situation.
The reference manual has been updated to describe the new feature.
The cc65 docs say VICE labels start with '.'. Also, output local
labels prefixed with '@', per ca65 convention. The default output
file is now "labels.lbl".
Added some minimal documentation.
(issue #151)
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.)
Added a pop-up menu with three options: default (curly quotes),
straight, and Merlin. Removed the "reset to defaults" buttons.
Also, slightly rearranged the Display Format tab so that the quick
set pop-up is on the left, near the items it affects. Moved the
"use comma-separated format for bulk data" checkbox over as well,
since it's part of the set.
This allows regions that hold variable storage to be marked as data
that is initialized by the program before it is used. Previously
the choices were to treat it as bulk data (initialized) or junk
(totally unused), neither of which are correct.
This is functionally equivalent to "junk" as far as source code
generation is concerned (though it doesn't have to be).
For the code/data/junk counter, uninitialized data is counted as
junk, because it technically does not need to be part of the binary.
This action removes operand formatting from all code and data in the
selected range. In most cases this is equivalent to simply editing
the various items and clicking the "default" format radio button,
but the feature can be used to remove data formats that end up inside
multi-byte instructions. Instructions with such formats cause warnings
and were tricky to fix.
Labels embedded in multi-byte items are also tricky to remove, so this
clears those as well. It does not remove visible labels. This is
done in a single pass, which means that labels that would become visible
after the formatting is cleared will still be removed.
Also, fix inclusion of address range end lines when restoring the
selection. Their peculiar nature -- being associated with the offset
of the last byte of multi-byte items -- was interfering with the
selection save code. This does not add them to the selection when
an address region deletion is undone, since technically they weren't
part of the selection.
Also, moved Edit Note higher in the Actions menu.
Added a warning to the index page that only appears when viewing it
over http/https. The issue is that the manual on the web reflects the
tip-of-tree sources, which may be inaccurate for whatever version the
user has.
Also, provide an alternate path to opening the manual in-app when
under development.
Move the SourceGen manual to a subdirectory in "docs", so that it can
be accessed directly from the 6502bench web site. The place where
it's installed in the distribution doesn't change.
