Transfers possession of keyboard mappings from the Mac side over to individual machines.
...
Specifically by establishing an intermediate representation of a useful mix between the American and British IBM and Mac keyboard layouts, and routing through that.

Causes the ZX80/81 to omit support for the wait line if being configured as a ZX80.

Arranges for the ZX80/81 to get a peek at target configuration prior to construction. I'm as yet undecided on whether to make this the norm.

Makes it optional whether the Z80 supports the wait line. If the wait line isn't in use, runtime costs are decreased because the optional wait cycles need not be iterated over.

Added the option not to include ready line support in the 6502 core, and took advantage of it in the Electron, Oric and Vic-20 implementations. Also tagged those as forceinline and/or override final where applicable.

Allows Z80 users to opt out of support for the bus request line. Which both now do.

Split the static analyser functionality so that it's possible just to ask for the set of media implied by a particular file. Extended ConfigurationTarget so that media alone can be pushed to a machine.

Ensured the ZX80 and '81 also provide the necessary hook for destruction.

Fixed: should be a full-path #ifdef guard, given that this is one of the classes named relative to its namespace.

Formally declared the ZX80/81 and Amstrad CPC as keyboard machines in their public interface. Which means not having to repeat the meaning of set_key_state and clear_all_keys. So: a minor DRY improvement.

Expanded interface so that an external machine caller can request a string be typed without any knowledge of whatever it intends to do re: CharacterMappers. Which is immediately useful in paste functionality.

Within the Typer framework: hatched out CharacterMapper as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part.

These should actually both be in the public header, as the types are used in an exposed method.
2017-08-02 22:18:30 -04:00

Made it no longer public knowledge that any sort of Typer is involved in being a ZX80/81.

Reinstated typing ability, albeit with an ugly inline insertion. But I think I can defer dealing with typers to another pull request. The whole issue of keyboard mapping probably needs reappraisal.

Breaking its typer for now, adapted the ZX80/81 to having a Z80, not being one.

Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.

Brought Typer into the new run_for orthodoxy, making it easier to clock consistently regardless of unit. Which necessitated adding a negative operator for WrappedInts.

Formalised set_interrupt_line's optional parameter as being a count of HalfCycles; corrected PartialMachineCycle.is_wait and effected the proper timing for counter reset on a ZX81.

Switched definitively to the works-for-now approach of requiring an explicit opt-in where somebody wants to clock a whole-cycle receiver from a half-cycle clock.

Adjusted the Z80 formally to communicate in terms of half cycles rather than whole.

Adapted the Z80's perform_machine_cycle to return Cycles.

Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts.

Eliminated redundant uses of ClockReceiver and sought to ensure that proper run_fors are inherited all the way down.

Converted the TimedEventLoop and the things that sit atop it into ClockReceivers.

Decided to follow through on Cycles and HalfCycles as complete integer-alikes. Which means giving them the interesting range of operators. Also killed the implicit conversion to int as likely to lead to type confusion.

Adapted the Z80 into a clock receiver, which also vends Cycles rather than a raw int within its PartialMachineCycle struct. The objective is to update it to vend HalfCycles within its struct, but I think I need to do some work on cycle/half-cycle arithmetic first.

Converted the ZX80/81 video component into a ClockReceiver. As it happens, it's most convenient to take the half-cycle bus here.

Switched CRTMachine over to use Cycles as an explicit statement of units, and followed through on the effects of that.

Factored out the table-lookup approach to being a typer, and adjusted so as definitely to limit myself to positive offset table lookups.

Fixed signed/unsigned comparison and potential negative table reference.

Chopped time accumulation out of the default Tape process because it's proving to be sufficiently expensive for a TZX as not to be worthwhile. Introduced a cheaper position capturing/restoring method.

Removed just-don't-power-the-tape approach to pausing and playing, in favour of being fully communicative.

Hardens the ZX80/81 video routines to ensure they never try to push data into the future and don't double-count time when pixels would ostensibly run into sync. You could previously see the CRT being handed negative run lengths if sync interrupted pixels or if a run of more than 320 pixels (my arbitrary buffer size) occurred, with corresponding poor behaviour given my use of unsigned numbers.

By observation, it appears that disabling vsync occurs on any port output whatsoever, as long as NMI isn't blocking it.

Removed data work if sync is enabled; in that case no data is output.

Introduced an explicit record of whether a video byte is latched. It's definitely incorrect to treat the latching of 0 as equivalent to no latching, as the byte that will eventually become video is not strongly implied.

Ensured bit 8 is uniquely from the latched video byte, not an OR of that with the refresh address.

Added a block on the tape motor for a short period after each time the ROM routine is intercepted for a substituted byte read. To reduce the collision between fast tape and real tape loading.

Reduced port writes which can adjust programmatic sync, and prevented anything while NMI generation is active. Moved line counter increment from triggered by interrupt acknowledge to triggered by horizontal sync. In both cases, cribbing from my own earlier work. Initial results suggest that sync issues are resolved in third-party software.
