The DisplayList update function was mis-handling the case where
there were no previous lines. This caused assertions to fire for
the case where you add a header comment to a project with no
existing header comment or EQUs.
Defined a simple monochrome bitmap format, and created some pieces
for a Tic-Tac-Toe game. Wrote a tutorial that explains how to
visualize them.
Also, updated some comments.
Thumbnails are now visible in the main list and in the visualization
set editor. They're generated on first need, and regenerated when
the set of plugins changes.
Added a checkerboard background for the visualization editor bitmap
preview. (It looks all official now.)
The Visualization and Visualization Set editors are now fully
functional. You can create, edit, and rearrange sets, and they're
now stored in the project file.
Implemented Apple II hi-res bitmap conversion. Supports B&W and
color. Uses essentially the same algorithm as CiderPress.
Experimented with displaying non-text items in ListView. I assumed
it would work, since it's the sort of thing WPF is designed to do,
but it's always wise to approach with caution. Visualization Sets
now show a 64x64 button as a placeholder for the eventual thumbnail.
Some things were being flaky, which turned out to be because I
wasn't Prepare()ing the plugins before using them from Edit
Visualization. To make this a deterministic failure I added an
Unprepare() call that tells the plugin that we're all done.
NOTE: this breaks all existing plugins.
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.
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.
To avoid confusing the assembler, expressions with a leading
parenthesis like "(foo & $ffff) + 1" are prefixed with a "0+". This
is not necessary if the operand begins with a '#'.
(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.
Most of the decorative items associated with a file offset are
placed before the item in the display list, and given a span of
zero. This yields the correct behavior in a binary search: an
exact match finds the decorative item (e.g. a blank line), while a
match partway into the instruction or multi-byte data item causes
the binary search to move on to the next line, where it's resolved.
The problem is that we were adding a blank line *after* instructions
in the no-continue case. If the binary search found the blank line
before it found the instruction, it would guess "too high" rather
than "too low", and miss the actual instruction line.
We now set a flag and add the blank line as part of the following
item. We do a little dance at the start to ensure that the blank
line doesn't disappear during a partial update.
It's possible to have format descriptors on instructions that are
left over from when the bytes were treated as data. Single-byte
formats were being allowed on single-byte instructions, which
confused things later when the code tried to apply the format to
an instruction with no operand.
