* Turned `core_file` into an implementation of `random_read_write`.
* Turned PNG errors into a standard error category.
* Added a helper for generating what look like derived classes on-the-fly.
- vecstream.h: Revert changes made in aa29519528. The std::string_view conversion has been made a non-member function (util::buf_to_string_view) and moved to coretmpl.h.
- strformat.h: Remove the using declaration importing util::string_format into the global namespace. It has been moved to emucore.h and a few tool sources; other references have been qualified.
- osdcore.h: Split out file, directory and path classes and methods to a new header (osdfile.h), Doxygenizing the documentation comments.
- Disaggregate many #includes that were including other standard or custom headers. emu.h now includes basically the same things that it did, but other headers have been streamlined; for instance, emucore.h no longer stealth-includes osdcore.h several ways.
- corefile.cpp, fileio.cpp: Change puts to take a std::string_view parameter
- rendlay.cpp: Use std::string_view instead of bare pointers in various functions
- vecstream.h: Add std::string_view conversion operator to obtain output buffer without needing to make it a C string with explicit null termination
- xmlfile.cpp: Add get_attribute_string_ptr method that distinguishes between empty strings and absent attributes without falling back to C strings
The previous behaviour was unintuitive - parsing an XML file and writing
it out immediately would produce invalid XML if the file contained any
characters that needed escaping. It makes far more sense to escape on
writing rather than expecting the user to escape input.
-Add preliminary support for visibility toggles to artwork system.
This allows the user to show/hide related elements in a view, with
nesting. The view can specify whether elements are shown or hidden by
default. Settings are saved per host window/screen per view. There is
no way to set the initial visibility state on the command line. Legacy
"Space Invaders cabinet model" layers are mapped onto visibility
toggles.
This is not stable yet. In particular, the XML element/attribute names
have not been finalised. The new features have not been added to
complay.py to prevent them from being used before they're finalised.
The option is called skip_warnings, and it must be set in ui.ini (it can
be set using the internal UI). Red warnings cannot be skipped; yellow
warning can be skipped under certain circumstances.
For a yellow warning to be skipped, the system must have been launched
in a way that allows warnings to be displayed, in a configuration with
the same set of devices flagged with unemulated/imperfect features,
within the last seven days, and the warning must have been displayed
within the past 14 days.
Also fixed a bug with display of the MACHINE_NO_COCKTAIL flag in the
internal UI, and increased the size of XML integer attributes to 64
bits.
* move stuff to namespace util::xml
* scope down some enums
* split config load/save delegate types
* make config load take const so it can't mangle data
* an empty tag and a self-closing tag are semantically equivalent, so std::string can be used saving some manual allocation
* a valid tag can't have an empty name, so that can be std::string too
* still expose empty strings as nullptr to API users
* scope down the int_format enum
* # is not £ ffs
Use standard uint64_t, uint32_t, uint16_t or uint8_t instead of UINT64, UINT32, UINT16 or UINT8
also use standard int64_t, int32_t, int16_t or int8_t instead of INT64, INT32, INT16 or INT8
