fmt was updated during the clang-format update, which breaks the previous implementation of FmtLogMessage
Changes were:
* Move definition of FmtLogMessage into log.h to use variadic templates as FMT_VARIADIC was removed
To supplement the change above:
* Move Entry and CreateEntry into log.h
* Add LogEntry in backend.cpp
* Uses PopWait to reduce the amount of busy waiting if there aren't many
new logs
* Opens the log file as shared on windows, letting other programs read
the logs, but not write to them while citra is running
* Flushes the logs to disk if a log >= error arrives
Adds a condition var to SPSCQueue so when a new log is pushed it will
wake the consumer thread that is calling PopWait. This only applies to
to queues with NeedSize=true
* Change the logging backend to support multiple sinks through the
Backend Interface
* Add a new set of logging macros to use fmtlib instead.
* Qt: Compile as GUI application on windows to make the console hidden by
default. Add filter configuration and a button to open log location.
* SDL: Migrate to the new logging macros
* Discard gas_mode renders
This discards the gas_mode / fog effect from games that use it and allows the games to display without it. Note that gas mode is still unimplemented and will LOG<CRITICAL>.
This bypasses #3287. (Doesn't fix it)
* fix clang
json.hpp wants it, but it isn't always available. Rather than patch
json.hpp directly to remove the dependency, provide a json.h wrapper
header that subs in std::experimental::string_view using preprocessor
magic. All the consumers of json.hpp are in src/web_service, so the
wrapper header is placed there as well.
Versions prior to this didn't compile on OpenBSD due to unconditional
use of the non-standard strtod_l() function.
The fmt::MemoryWriter API has been removed in the intervening
versions, so replace its use with fmt::memory_buffer and fmt::format_to.
The library also no longer provides the fmt::fmt ALIAS, so define
it in externals/CMakeLists.txt.
