or from the user. Before this is done, the parser needs to recognize
variable-length labels (right now, it used fixed spacing and assumes
the largest label is 8 characters).
Fixed bug in Distella; a label was being printed with an incorrect
quote symbol, which would break parsing of that line.

The file selector in Windows now ignores all items starting with '.', not just the directories '.' and '..'. This is most apparent when using the Windows port and browing Linux shares, which shows many dot files.

key. This enables automatically taking snapshots every X seconds
while in emulation mode. The interval (in seconds) can be set
with the 'ssdelay' commandline argument.
Some minor cleanups to the EventHandler methods, making them
const when possible.
Added latest DPC+ changes from Spiceware.
Fixed issue with ROMs that run entirely from ZP RAM; no disassembly
was being generated when entering the debugger. For now, this
special case is detected, and the disassembly is generated for
the code that ran before the PC entered ZP RAM space. Eventually,
this will go away when the Distella fully supports disassembling
below 0x1000.

informs the rest of the system about how a page of address
space is to be treated (READ, WRITE, READWRITE). This makes it
much easier to track if a read from the write port has occurred.
As such, the _rwport command should now be somewhat faster.
Eventually, the debugger/disassembler will use this info to
colorize the output.

'Stephen Anthony' (aka, me) in addition to Brad Mott as copyright
holders for Stella. I think I've been with the project long
enough now (almost 10 years) to justify being specifically mentioned
above and beyond 'the Stella Team'.

to 'resolvedata', since that more accurately describes what it does.
Also, it now accepts arguments as strings (never, always, auto)
instead of 0, 1, 2.
Updated main documentation for changes in OSX port 'basedir'.
Updated debugger documentation for recent command additions, and
provided new snapshots where the UI has changed.
It seems to be getting close to a new release - perhaps this
coming Friday.

Removed final traces of SpeakJet emulation (the SpeakJet class).
It doesn't look this is ever going to be resurrected.
Tab completion results in the debugger prompt widget are now sorted.

the completion now includes functions (built-in and user-defined).
Cleaned up some more of the debugger documentation, mostly
related to tab completion.

The debugger 'disasm' command now works again for addresses below
0x1000, and it also now correctly accepts the number of lines to
output in the disassembly.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1989 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
Partial cleanup of the debugger 'help' command, making the output line
up a little nicer. More work is required in this area.
Fixed bug in EditableWidget; setEditString now implies that editing will
be started (if it's been enabled).

class to the CartDebug class, since it's really a debugger feature.
Fixed comments on some of the methods in CartDebug.

whether the range 0x1000 - 0x1FFF (aka cart space) has been modified, and
if so, it forces a re-disassembly. Still TODO is modify all the cart
classes that manually handle poke operations to set the page as dirty
when a write actually succeeds.

doesn't result in the PC being present. This fixes some bugs in the more
esoteric bankswitch schemes, and also enables rewind to show the correct
disassembled results.

over onto the opposite side of the screen. Breakpoints set by clicking
in RomListWidget only apply if they've actually been enabled. This
fixes a bug whereby a breakpoint could look like it is enabled when
it really isn't. Related to this, breakpoints cannot be set for
disassembly lines that don't contain a valid address or an empty
bytes area (basically, empty lines and lines containing '.byte' items).

disassembler. Hopefully this will lead to a new release very soon.
Added 'autocode' commandline argument and associated UI item (in the
RomWidget debugger area), which controls how Distella will use the
'automatic code determination' option. If set to 0/never, this is
completely disabled. If set to 1/always, it is always enabled.
The default is 2/automatic, whereby it is first turned on, and then
turned off if the disassembly doesn't contain the current PC address.
RomListWidget has now been completely reworked, so that it informs
RomWidget of its intent to change breakpoints and patch ROM. If
either of these fail, the action won't be performed, and more
importantly, it won't appear onscreen as if the action has succeeded.
This fixes an old bug whereby patching could fail, yet the onscreen
ROM data was actually changed. Related to this, the list has been
made as efficient as possible, and its contents are never un-necessarily
copied. Also, lines in the disassembly that cannot be modified no
longer show an edit area.
Due to the way the new disassembly works, you can no longer switch between
banks in the RomWidget (Distella would probably fail to disassemble in
such as case).
EditTextWidget can now indicate its contents have changed when adding
text to it.

This is very useful for conditional re-disassembly, since many bankswitch
schemes consist of ROM only, and once disassembled, cannot possibly have
a different disassembly at some later point. This is mostly done for such
static schemes (2K, 4K, etc), but more work is required for carts with
extended RAM. Basically, the cart knows best how its been accessed, so
it makes sense to have the hints there.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1965 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
handling to C++ stringstreams instead of C-style character arrays,
which fixed some segfaults (sprintf is evil).
First pass at tying the number of banks to the disassembly. The idea
is that the startup bank (which is now identified by the cart) always
starts at address at 0xfffc, while the other banks are defined by the
PC at the first time we enter the debugger. This is still a WIP,
since there's no actual checking done yet to see if the current PC
is in the current disassembly.
Added 'ctrlcombo' commandline argument, which completely disables
checking for Control-x key combos. This is useful when playing
2-player games where the 'f', 'r' and 'Control' keys are supposed
to be treated separately. Previously, pressing Control and 'r' or
'f' processed some other action (change framerate, reload rom, etc).

the debugger commandline are now reflected in most parts of the debugger UI.
Still TODO is have DiStella use those labels in the disassembly, and deal
with the formatting issues this will entail.
Still completely broken are built-in functions, getting an equate address
based on label, and tab-completions.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1963 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
the RomListWidget instead of being printed to the terminal. There are still
graphical glitches with this, but for a first pass, it's nice to see actual
Distella output in Stella.
Partially working 'disasm' command from the PromptWidget. Currently, it
only disassembles cart address space (aka, 0x1000 or above).
Removed the old disassembly code from CartDebug. Still TODO is fix the
label stuff, both in getting DiStella to use it, and adding/removing
labels. This is greatly reduced now that we only have to worry about
user labels.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1934 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
methods from Debugger directly. As well, the start address is now passed
into DiStella::disassemble() directly; decision to start from the reset
vector is done outside DiStella. This is in preparation for starting
the disassembly from any valid address.

from within Stella (vs. reading ROM data from a file).
Compilation is currently broken.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@1931 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
classes. First off, the distella code has been integrated into a
DiStella class. This code isn't yet tied to the debugger, but it does
at least compile and generate valid output.
The RamDebug class has been replaced by a CartDebug class, which
takes responsibility for the previous RamDebug stuff as well as
things related to Cart address space (read from write ports,
disassembly, etc).
Fixed E7 bankswitching when reading from the write port in the upper
256byte area.
Fixed 'read from write port functionality' in general for all carts
that supported it previously. Basically, if _rwport is enabled, the
address is checked to be an actual read (vs. one that's part of a
normal write cycle), *and* it's actually an illegal access (each
cart/bankswitch type now provides a hint to indicate this condition).
Still TODO is clean up the rework, properly integrate DiStella, and
fix labels and defines (which seem to be completely broken).
