ImGui::Text() assumes that the incoming text is intended to be
formatted, but we don't actually use it to format anything. We can be
explicit by using the relevant function.
This also has a plus of not needing to go through the formatter itself,
but the gains from that are probably minimal.
Previously these functions were declared without the static specifier,
giving them external linkage, which isn't really ideal.
Instead, we can place these functions up by the relevant file-scope
variables and place them inside an anonymous namespace with said variables,
giving them internal linkage.
Avoids the use of the null pointer to represent an empty string.
Instead, we can simply pass an empty string_view instance. Using
std::string_view enforces this invariant at the API level.
Due to the lack of cast here, this will actually print out the ascii
value, rather than the character itself, due to promoting to integral
values. Instead, we can eliminate the use of character operands and just
print the value itself directly, given it's equivalent behavior with
less code.
Allows these arrays to be placed within the read-only segment (and
enforces the immutability in the code itself). While we're at it, we can
make use of std::array here.
Now that the std::map less-than comparitor is capable of being used with
heterogenous lookup, we're able to convert many of the querying
functions that took std::string references over to std::string_view.
Now these functions may be used without potentially allocating a
std::string instance unnecessarily.
Previously, when performing find() operations or indexing operations on
the section map, it would need to operate on a std::string key.
This means cases like:
map.find(some_string_view)
aren't usable, which kind of sucks, especially given for most cases, we
use regular string literals to perform operations in calling code.
However, since C++14, it's possible to use heterogenous lookup to avoid
needing to construct exact key types. In otherwords, we can perform the
above or use string literals without constructing a std::string instance
around them implicitly.
We simply need to specify a member type within our comparison struct
named is_transparent, to allow std::map to perform automatic type
deduction.
We also slightly alter the algorithm to an equivalent compatible with
std::string_view (which need not be null-terminated), as strcasecmp
requires null-terminated strings.
While we're at it, we can also provide a helper function to the struct
for comparing string equality rather than only less than. This allows
removing other usages of strcasecmp in other functions, allowing for the
transition of them to std::string_view.
fmt diverges from printf in that '.' as a precision specifier may only
be used for floating-point values (makes sense, given it's indicating
precision after the decimal point).
This fixes the problem where OBS game capture only grabs the region
inside an ImGui window whenever one is open, when using the OpenGL
backend. Shouldn't have any negative effects, as the scissor would've
been something completely arbitrary anyways.
This may affect other capture software that uses the same hooking
method, but I've only tested OBS.
In a few cases we needed to alter... less than ideal parameter types.
While u8 may have been OK with printf-style formatting, which promotes
most smaller types back to int, this won't work with fmt. fmt preserves
the type of the passed in arguments, meaning that u8, being an alias of
uint8_t (itself being an alias of unsigned char on all the platforms we
support), will print out as a character, not a numeric value.
As such, we amend some functions to operate on u32 values for two
reasons:
1. We actually want it to print out as a value
2. Arithmetic on unsigned types smaller than unsigned int will actually promote to an int,
not unsigned int. This is very non-obvious to some and makes for
error-prone code. < sizeof(int) types are great for storage, not so
much for performing unsigned arithmetic, despite the signedness of
the type.
While we do have this library as part of the public linkage interface in
the common library target, which will be used in the future for the
logging macros, we should still be explicit that we're using this
library. Therefore, we privately link it in to be explicit about it.
Begins the transition to using fmt for string formatting where
applicable. Given fmt supports formatting std::string instances out of
the box, we can remove now-unnecessary calls to .c_str() and .data().
Note that this change does not touch the actual logging subsystem aside
from converting the final StringFromFormat call in the process over to
fmt::format. Given our logging system is heavily used throughout the
entire codebase, and converting that over will be quite a large change
by itself, this will be tackled near the end of the conversion process.
Currently, it is possible for the DiscordHandler thread to be in the
middle of sleeping when Dolphin is closing. This results in a very
noticeable delay of up to 2 seconds that is unacceptable, especially
for people who don't use the Discord integration.
This fixes the issue by making the thread wait on an Event instead
and signalling it when shutting down.
Allows us to migrate off of printf specifiers and have more type-safe
formatting facilities. It also allows for custom type support as well.
fmt is also on track to have part of it standardized within C++2a, so
this will also lessen the transitional work necessary later on by
allowing new code to use it.
This simply adds the library but doesn't do anything with it yet.
It already is disabled for other backends, but this didn't happen with the software renderer. Attempting to change it while running causes the change to visually happen (including switching to the normal render settings UI instead of the barren one for the software renderer), but doesn't actually change the backend itself (it'll still use the software renderer at the next launch).
Previously, this array potentially wouldn't be placed within the
read-only segment, since it wasn't marked const. We can make the lookup
table const, along with any other nearby variables.
