- removed ErrorID, using the error message as the ID
- works just as well and simplifies maintenance
- the messages should be moved to the relevant packages OR to a
locale package. not sure which yet.
- implemented Has() function
- Error() now de-duplicates error string parts
* for example, instead of:
error: foo: foo: bar
Error() will now return:
error: foo: bar
- renamed FormattedError to AtariError
- renamed NewFormattedError to New
- implemented Is() and IsAny() for more convenient testing
+ changed all error testing to use Is() and IsAny()
- renamed FatalError to PanicError to better indicate the intent
- improved how command template are compiled
- verification and tab completion is now more robust
- missing repeat groups
o debugger
- extended PLAYER and MISSILE commands
- combined STICK1 and STICK2 into one STICK command
- refactored SDL television
- implemented close window for SDL windows
- backquote key toggles screen-mode (debug guides on/off)
- window resizes to fit screen-mode
- sketched in mouse support for SDL implementation
- the intention here is to be able to select breakpoints
with the mouse
o concurrency
- made sure shared memory is locked for all go routines
o errors
- reworked gopher errors a little
- added SYMBOL command. searches for address label, returns
address
- fixed disassembly output for ROMs without a symbol file
- improved disassembly a little bit. now attempts to disassemble
entire of cartridge memory and doesn't bail out of loop
at first sign of an unimplemented instruction. cpu
package now returns a ProgramCounterCycled error when
program counter reads past end of memory
o video
- tweaked horizontal movement
- fixed player vertical delay (tested with Pitfall ROM)
- fixed ball enable detection (0x02 not 0x20. doh!)
o cpu
- implemented LAX command
- renamed 3 byte NOP to DOP
- added program counter information to unimplemented instruction
error
o gopher 2600
- error message now returned and displayed in run mode
o
- symbol loading
- printing of disassembly now uses symbols (if available)
- run mode disasm now works as expected
o errors
- added GopherError - started to replace calls to fmt.Errorf()
with instantiations of GopherError
o debugger
- prompt now shows (brief) disassembly of next instruction to be
executed
