The new t.graphics.debug flag controls the following:
- If enabled, a debug context is created
- If disabled, a no-error context is created
- If enabled, GL debug messages are forwarded to lovr.log
Add entrypoints, headset backend code, fill in the Activity, and
add various special cases to account for the asynchronous render loop,
lack of sRGB support, and OpenGL state resets.
I added header files with #include to prevent the implicit declaration warnings and fixed a typo in function size_t lovrPlatformGetExecutablePath(char* buffer, size_t size).
lovr.log is a new callback that is invoked whenever LÖVR wants to
send the project a message. For example, this could be a performance
warning from the graphics module, an error message from one of the
headset backends, or an API deprecation notice.
The callback's signature is (message, level, tag). The message is a
string containing the message to log, level is a string that is currently
one of "debug", "info", "warn", "error", and tag is an optional string
that is used to indicate the source of the message for grouping purposes.
The default implementation of the callback just prints the message,
but the callback can be overridden to do things like filter messages,
write them to a file, or even render them in VR. Projects can also
invoke the callback directly to log their own messages.
Usually these are more of a platform-specific concept, and they
don't really interact with files or do any io.
There is a little bit of duplication among the *nix platforms since
they're similar, but overall this organization feels a bit better.
