-PUGL
+Pugl
====
-Pugl is a minimal portable API for GUIs which supports embedding and is
-suitable for use in plugins. It works on X11, Mac OS X, and Windows. GUIs can
-be drawn with OpenGL or Cairo.
+Pugl (PlUgin Graphics Library) is a minimal portable API for GUIs which is
+suitable for use in plugins. It works on X11, MacOS, and Windows, and
+optionally supports OpenGL and Cairo graphics contexts.
-Pugl is vaguely similar to GLUT, but with some significant distinctions:
+Pugl is vaguely similar to libraries like GLUT and GLFW, but with some
+distinguishing features:
- * Minimal in scope, providing only what is necessary to draw and receive
- keyboard and mouse input.
+ * Minimal in scope, providing only a thin interface to isolate
+ platform-specific details from applications.
- * No reliance on static data whatsoever, so the API can be used in plugins or
- multiple independent parts of a program.
+ * Zero dependencies, aside from standard system libraries.
- * Single implementation, which is small, liberally licensed Free / Open Source
- Software, and suitable for direct inclusion in programs if avoiding a
- library dependency is desired.
+ * Support for embedding in native windows, for example as a plugin or
+ component within a larger application that is not based on Pugl.
- * Support for embedding in other windows, so Pugl code can draw to a widget
- inside a larger GUI.
+ * Simple and extensible event-based API that makes dispatching in application
+ or toolkit code easy with minimal boilerplate.
- * More complete support for keyboard input, including additional "special"
- keys, modifiers, and support for detecting individual modifier key presses.
+ * Suitable not only for continuously rendering applications like games, but
+ also event-driven applications that only draw when necessary.
-For more information, see <http://drobilla.net/software/pugl>.
+ * Explicit context and no static data whatsoever, so that several instances
+ can be used within a single program at once.
+
+ * Small, liberally licensed Free Software implementation that is suitable for
+ vendoring and/or static linking. Pugl can be installed as a library, or
+ used by simply copying the headers into a project.
+
+Stability
+---------
+
+Pugl is currently being developed towards a long-term stable API. For the time
+being, however, the API may break occasionally. Please report any relevant
+feedback, or file feature requests, so that we can ensure that the released API
+is stable for as long as possible.
+
+Distribution
+------------
+
+Pugl is designed for flexible distribution. It can be used by simply including
+the source code, or installed and linked against as a static or shared library.
+Static linking or direct inclusion is a good idea for plugins that will be
+distributed as binaries to avoid dependency problems.
+
+If you are including the code, please use a submodule so that suitable changes
+can be merged upstream to keep fragmentation to a minimum.
+
+When installed, Pugl is split into different libraries to keep dependencies
+minimal. The core implementation is separate from graphics backends:
+
+ * The core implementation for a particular platform is in one library:
+ `pugl_x11`, `pugl_mac`, or `pugl_win`. This does not depend on backends or
+ their dependencies.
+
+ * Backends for platforms are in separate libraries, which depend on the core:
+ `pugl_x11_cairo`, `pugl_x11_gl`, `pugl_mac_cairo`, and so on.
+
+Applications must link against the core and at least one backend. Normally,
+this can be achieved by simply depending on the package `pugl-gl-0` or
+`pugl-cairo-0`. Though it is possible to compile everything into a monolithic
+library, distributions should retain this separation so that GL applications
+don't depend on Cairo and its dependencies, or vice-versa.
+
+Distributions are encouraged to include static libraries if possible so that
+developers can build portable plugin binaries.
+
+Testing
+-------
+
+There are a few unit tests included which can be run with `python waf test
+--gui-tests`, but unfortunately manual testing is still required.
+
+Several example programs are included that serve as both manual tests and
+demonstrations:
+
+ * `pugl_embed_demo` shows a view embedded in another, and also tests
+ requesting attention (which happens after 5 seconds), keyboard focus
+ (switched by pressing tab), view moving (with the arrow keys), and view
+ resizing (with the arrow keys while shift is held). This program uses only
+ very old OpenGL and should work on any system.
+
+ * `pugl_window_demo` demonstrates multiple top-level windows.
+
+ * `pugl_gl3_demo` demonstrates using more modern OpenGL where dynamic loading
+ and shaders are required. It can also be used to test performance by
+ passing the number of rectangles to draw on the command line.
+
+ * `pugl_cairo_demo` demonstrates using Cairo on top of the native windowing
+ system (without OpenGL), and partial redrawing.
+
+ * `pugl_print_events` is a utility that prints all received events to the
+ console in a human readable format.
+
+All example programs support several command line options to control various
+behaviours, see the output of `--help` for details. Please file an issue if
+any of these programs do not work as expected on your system.
+
+Documentation
+-------------
+
+The [API reference](https://lv2.gitlab.io/pugl/) for the latest master is
+available online, and can also be built from the source code by configuring
+with `--docs`.

+This is the API documentation for Pugl.
+This documentation is based around the [C API](@ref pugl_api),
+there is also a [C++ API](@ref pugl) in the `pugl` namespace.
+
+The Pugl API revolves around two main objects:
+the [World](@ref world) and the [View](@ref view).
+An application creates a single world to manage top-level state,
+then creates one or more views to display.
+
+## World
+
+The [World](@ref world) contains all top-level state,
+and manages views and the event loop.
+
+A world must be [created](@ref puglNewWorld) before any views,
+and it must outlive all views.
+
+## View
+
+A [View](@ref view) is a drawable region that receives events.
+
+Creating a visible view is a multi-step process.
+When a new view is [created](@ref puglNewView),
+it does not yet represent a real system view or window.
+To display, it must first have a [backend](@ref puglSetBackend)
+and [event handler](@ref puglSetEventFunc) set,
+and be configured by [setting hints](@ref puglSetViewHint)
+and optionally [adjusting the frame](@ref frame).
+
+The [Backend](@ref PuglBackend) controls drawing for a view.
+Pugl includes [Cairo](@ref cairo) and [OpenGL](@ref gl) backends,
+as well as a [stub](@ref stub) backend that creates a native window with no drawing context.
+
+
+Once the view is configured,
+it can be [realized](@ref puglRealize) and [shown](@ref puglShowWindow).
+By default a view will correspond to a top-level system window.
+To create a view within another window,
+it must have a [parent window set](@ref puglSetParentWindow) before being created.
+
+
+## Events
+
+[Events](@ref events) are sent to a view when it has received user input or must be drawn.
+
+Events are handled by the [event handler](@ref PuglEventFunc) set during initialisation.
+This function is called whenever something happens that the view must respond to.
+This includes user interaction like mouse and keyboard input,
+and system events like window resizing and exposure.
+
+## Event Loop
+
+The event loop is driven by repeatedly calling #puglUpdate which processes events from the window system,
+and dispatches them to views when necessary.
+
+Typically, a plugin calls #puglUpdate with timeout 0 in some callback driven by the host.
+A program can use whatever timeout is appropriate:
+event-driven applications may wait forever,
+or for continuous animation,
+use a timeout that is a significant fraction of the frame period
+(with enough time left over to render).
+
+Redrawing can be requested by calling #puglPostRedisplay or #puglPostRedisplayRect,
+which post expose events to the queue.
+Note, however, that this will not wake up a blocked #puglUpdate call on MacOS
+(which does not handle drawing via events).
+For continuous redrawing, call #puglPostRedisplay when a #PUGL_UPDATE event is received.
+This event is sent before views are redrawn,
+so can be used as a hook to expand the update region right before the view is exposed.
+
+## Error Handling
+
+Most functions return a [Status](@ref status) which should be checked to detect failure.

+ * The last semantic modification to khrplatform.h was at commit ID:
+ * 67a3e0864c2d75ea5287b9f3d2eb74a745936692
+ *
+ * Adopters may modify this file to suit their platform. Adopters are

+ * group so that they can be included in future versions of this file.
+ * Please submit changes by filing pull requests or issues on

+ *
+ * See the Implementer's Guidelines for information about where this file
+ * should be located on your system and for more details of its use:
+ * http://www.khronos.org/registry/implementers_guide.pdf
+ *
+ * This file should be included as
+ * #include <KHR/khrplatform.h>
+ * by Khronos client API header files that use its types and defines.
+ *
+ * The types in khrplatform.h should only be used to define API-specific types.
+ *
+ * Types defined in khrplatform.h:
+ * khronos_int8_t signed 8 bit
+ * khronos_uint8_t unsigned 8 bit
+ * khronos_int16_t signed 16 bit
+ * khronos_uint16_t unsigned 16 bit
+ * khronos_int32_t signed 32 bit
+ * khronos_uint32_t unsigned 32 bit
+ * khronos_int64_t signed 64 bit
+ * khronos_uint64_t unsigned 64 bit
+ * khronos_intptr_t signed same number of bits as a pointer
+ * khronos_uintptr_t unsigned same number of bits as a pointer
+ * khronos_ssize_t signed size
+ * khronos_usize_t unsigned size
+ * khronos_float_t signed 32 bit floating point
+ * khronos_time_ns_t unsigned 64 bit time in nanoseconds
+ * khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+ * nanoseconds
+ * khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ * khronos_boolean_enum_t enumerated boolean type. This should
+ * only be used as a base type when a client API's boolean type is
+ * an enum. Client APIs which use an integer or other type for
+ * booleans cannot use this as the base type for their boolean.
+ *
+ * Tokens defined in khrplatform.h:
+ *
+ * KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+ *
+ * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.

+/**
+ @file pugl_gl3_demo.c An example of drawing with OpenGL 3.
+
+ This is an example of using OpenGL for pixel-perfect 2D drawing. It uses
+ pixel coordinates for positions and sizes so that things work roughly like a
+ typical 2D graphics API.
+
+ The program draws a bunch of rectangles with borders, using instancing.
+ Each rectangle has origin, size, and fill color attributes, which are shared
+ for all four vertices. On each frame, a single buffer with all the
+ rectangle data is sent to the GPU, and everything is drawn with a single
+ draw call.
+
+ This is not particularly realistic or optimal, but serves as a decent rough
+ benchmark for how much simple geometry you can draw. The number of
+ rectangles can be given on the command line. For reference, it begins to
+ struggle to maintain 60 FPS on my machine (1950x + Vega64) with more than
+ about 100000 rectangles.

+ This event represents low-level key presses and releases. This can be used
+ for "direct" keyboard handing like key bindings, but must not be interpreted
+ as text input.
- A key press may be part of a multi-key sequence to generate a wide
- character. If `filter` is set, this event is part of a multi-key sequence
- and should be ignored if the application is reading textual input.
- Following the series of filtered press events, a press event with
- `character` and `utf8` (but `keycode` 0) will be sent. This event will have
- no corresponding release event.
+ Keys are represented portably as Unicode code points, using the "natural"
+ code point for the key where possible (see #PuglKey for details). The #key
+ field is the code for the pressed key, without any modifiers applied. For
+ example, a press or release of the 'A' key will have #key 97 ('a')
+ regardless of whether shift or control are being held.
- Generally, an application should either work with raw keyboard press/release
- events based on `keycode` (ignoring events with `keycode` 0), or
- read textual input based on `character` or `utf8` (ignoring releases and
- events with `filter` 1). Note that blindly appending `utf8` will yield
- incorrect text, since press events are sent for both individually composed
- keys and the resulting synthetic multi-byte press.
+ Alternatively, the raw #keycode can be used to work directly with physical
+ keys, but note that this value is not portable and differs between platforms
+ and hardware.

- drawing code (for example, by swapping buffers).
+ If supported, the event will be delivered to the view via the event loop
+ like other events. Note that this function only works for certain event
+ types, and will return PUGL_UNSUPPORTED_TYPE for events that are not
+ supported.
