2019-11-21Check explicitly for GLX and only link against the necessary libraryDavid Robillard1-2/+10
It turns out that on some systems GLX is implemented in libGLX (which brings in only libGLdispatch), while on others it is implemented in libGL.
2019-11-21Rename "backend" headersDavid Robillard20-165/+234
Working on Vulkan clarified what has always been slightly smelly about the design and organization here: not everything that is API specific is really in a "backend" (a PuglBackend). The concrete example is puglGetProcAddress(), which only makes sense for GL and is actually implemented in the "backend" files. Arguably puglGetContext() is also such a thing. So, rename the headers so they can be the place where API-specific things go in general, which happens to include a backend most of the time. The stub is a bit of an exception to this, but whatever. The includes look tidier this way. In place of the old headers are compatibility stubs that just emit a warning and include the new version, which will be maintained for a while.
2019-11-21Use consistent include guardsDavid Robillard5-15/+15
2019-11-21X11: Remove libGL dependency from GL backendDavid Robillard2-4/+1
This was the only use of actual GL in the backend, and I'm relatively sure this flush is pointless anyway. If, for some bizarre reason, anyone really wants to run without double buffers, they are always free to flush themselves.
2019-11-21Clean up configuration codeDavid Robillard1-48/+58
2019-11-20Mac: Move puglGetProcAddress() to mac_gl.mDavid Robillard2-17/+17
2019-11-20Mac: Fix unused parameter warningDavid Robillard1-1/+1
2019-11-18Cleanup: Remove unnecessary includesDavid Robillard4-6/+0
2019-11-18Move puglGetProcAddress to pugl_gl_backend.hDavid Robillard2-11/+11
This establishes a general pattern for backend-specific APIs, so that pugl.h doesn't become a mess. The name of these headers, and the definition of "backend", is a little fuzzy here, but it was before in reality anyway.
2019-11-18Add test utility function for logging errorsDavid Robillard5-16/+23
2019-11-18Ignore clang-tidy warnings in system headersDavid Robillard1-1/+1
2019-11-18Add error checking option to test programsDavid Robillard3-1/+8
2019-11-17X11: Don't select on server socket if events are already queuedosch1-1/+3
2019-11-17X11: Support pasting (almost) arbitrarily long textDavid Robillard1-1/+1
This is a bit ridiculous, but using a "probably big enough" value seems to be what everyone does. This particular value is the one used by Gtk.
2019-11-17X11: Don't send expose events to invisible windowsDavid Robillard1-1/+3
2019-11-17X11: Track visibility via system eventsDavid Robillard1-3/+8
This ensure that visibility is properly updated when a window is made visible or invisible by the user or window system. Unfortunately it does not seem to propagate automatically to child windows, but this is at least better than the previous situation, and good enough for most cases.
2019-11-17Use typedefs for flag typesDavid Robillard1-72/+82
This doesn't change anything about type-safety (C can't do that), but at least makes the intent of things clearer.
2019-11-17Cleanup: Use consistent formatting for field documentationDavid Robillard1-141/+141
2019-11-09Add clang-tidy file and update lint targetDavid Robillard2-20/+27
2019-11-09Fix various clang-tidy warningsDavid Robillard5-18/+20
2019-11-09Make pugl_gl3_test deterministicDavid Robillard1-16/+15
2019-11-09Add puglStrerror() and improve test program error reportingDavid Robillard5-8/+41
2019-11-03Remove redisplay flag and add puglPostRedisplayRect()David Robillard8-36/+84
2019-11-03X11: Only merge expose events if they intersectDavid Robillard1-13/+45
Towards actual fine-grained exposure. This uses the previous behaviour if expose events intersect to reduce redundant drawing, but dispatches expose events immediately (after flushing and pending configure events) if they don't to support partial redraws.
2019-11-03Add puglGetNativeWorld()David Robillard4-0/+28
2019-11-03Windows: Do not require backends to have a surfaceDavid Robillard1-1/+1
This was just leftover cruft from before error handling was cleaned up, any failure to configure must now be reported by the backend.
2019-11-03Add pugl_print_events test programDavid Robillard2-0/+85
2019-11-03Expose functional stub backendDavid Robillard4-1/+79
2019-11-03Move platform stub configuration code to platform headersDavid Robillard4-33/+43
This allows backends which use basic software rendering (like Cairo) to share the common basic window format setup code.
2019-11-03Add stub implementations of backend functionsDavid Robillard5-63/+115
Towards having actual trivial backends, but in general allows backends to not declare functions they don't care about which is nice and already a net reduction of actual code.
2019-11-03Add verbose option to test programs to print all eventsDavid Robillard3-13/+49
2019-11-03Fix puglFreeView() crashes when window creation failedJordan Halase4-14/+29
2019-11-03Cleanup: Fix whitespaceDavid Robillard1-1/+1
2019-11-03Fix duplicate word in error messageDavid Robillard1-1/+1
2019-11-03Windows: Fix GL context flagsDavid Robillard1-0/+1
2019-10-21Don't use compatible profile in pugl_gl3_testDavid Robillard1-1/+1
It turns out that there are some systems where having this on makes things not work, because compatible profiles are only supported up to earlier versions, despite a much higher version being available.
2019-10-15Mac: Remove unused method declarationDavid Robillard1-1/+0
2019-09-16Fix memory leakDavid Robillard1-0/+1
2019-09-14Windows: Fix Cairo backend buildDavid Robillard1-18/+18
2019-09-14Add support for using a debug OpenGL contextDavid Robillard3-1/+8
2019-09-14Wrap deprecated declarations in PUGL_DISABLE_DEPRECATEDDavid Robillard1-0/+4
This allows projects that use strict warning flags to suppress warning noise.
2019-09-07Build documentation on CIDavid Robillard2-1/+21
2019-09-07Improve documentation and use LV2 documentation styleDavid Robillard9-115/+1212

2019-09-03Make almost everything return a statusDavid Robillard5-37/+60
Prepares the API for proper error handling, even though there isn't any for these functions yet.
