Proudly announcing the release of a brand-new project emscripten-ports.

The goal of this project is to collect ports that are not part of Emscripten.

The first port released is for ImGui, a bloat-free Graphical User interface for C++ with minimal dependencies.

Released emscripten-glfw 3.4.0.20241004 with the following changes:

• Implemented custom cursors (glfwCreateCursor)
  • uses a canvas to draw the cursor image into it and convert it into a URL (canvas.toDataURL())
  • uses the CSS property syntax: cursor: url(xxx) xhot yhot, auto when calling glfwSetCursor with a custom cursor

Published a blog post properly introducing emscripten-glfw.

You can read about the history of the project and some of the primary features.

Pushed WebGPU Shader Toy update: v2024.09.08

• Added a History menu to undo/redo Shader level changes.
• Added a Quick Export shortcut (Cmd + S / Ctrl + S).
• Added the ability to reset the settings only.
• Added a way to import a shader given a URL.
• Moved some examples outside the code and imported via URL.
• Added 2 examples: Fire and Marble.

Released emscripten-glfw 3.4.0.20240907 with the following changes:

• Fixed Meta/Super key workaround to also handle the rare (but possible) use-case of having other keys down before pressing the Meta/Super key

Pushed WebGPU Shader Toy update: v2024.08.18

• Added support for macOS keyboard shortcuts.
• Changed the “Compile Shader” shortcut to be Ctrl + D (resp. Cmd + D) as Cmd + Space is already taken.
• Added an alternate way of rendering the shader in fullscreen mode: holding the Alt key preserves the size/ratio of the shader window.
• Upgraded emscripten-glfw to v3.4.0.20240817 which enables using macOS shortcuts and copy/paste in any text field (not just the editor).

Released emscripten-glfw 3.4.0.20240817 with the following changes:

• Major clipboard changes: the clipboard now uses the browser events to handle cut, copy and paste
• Added a way to tweak the timeouts for the Super + Key workaround (Super is also known as Meta or Cmd)
• Added a way to set which keys are allowed to be handled by the browser
• Added a convenient API to open a URL (emscripten::glfw3::OpenURL)
• Added a convenient API to detect if the runtime platform is Apple (emscripten::glfw3::IsRuntimePlatformApple), mostly used for keyboard shortcuts (Ctrl vs. Cmd).
• Added GLFW/emscripten_glfw3_version.h with EMSCRIPTEN_GLFW_VERSION define for compilation time version detection
• EMSCRIPTEN_USE_PORT_CONTRIB_GLFW3 port define now also contains the version

Breaking changes:

• The clipboard async API has been removed.
• Check the Clipboard support section for details on how to deal with the clipboard in your application.

Released emscripten-glfw 3.4.0.20240804 with the following changes:

• Fixed nullptr issue when clipboard is empty
• Fixed the internal clipboard being wiped on asynchronous callback error

The source code for WebGPU Shader Toy is now available on github.

Released emscripten-glfw 3.4.0.20240731 with the following changes:

• Added emscripten_glfw_get_clipboard_string the C version of emscripten::glfw3::GetClipboardString to retrieve the clipboard asynchronously
• Added a helper class emscripten::glfw3::FutureClipboardString to greatly simplify the more frequent use-cases
• GetClipboardString::value() now returns the internal clipboard in case of error, instead of throwing exception
• Added optimizationLevel option to the emscripten port

Pushed WebGPU Shader Toy update: v2024.07.29

• Added the ability to swap the panes

Released emscripten-glfw 3.4.0.20240727 with the following release notes:

• Introduced C++ API (namespace emscripten::glfw3) included with GLFW3/emscripten_glfw3.h:
  • provides a more correct API with sensible defaults (ex: std::string_view / std::optional<std::string_view> vs char const * which may or may not be nullptr)
  • allow for C++ only API (ex: std::future)
  • the C API is still available if you would rather stick to it
• Implemented emscripten::glfw3::GetClipboardString (C++ only) which provides a way of fetching the global clipboard in a browser environment (glfwGetClipboardString is not the right API due to the asynchronous nature of the underlying platform API).
• The cursor position is no longer clamped to the window size, and as a result, can have negative values or values greater than the window size. Note that GLFW implements a similar behavior on the macOS desktop platform.
• Implemented glfwSetWindowPosCallback
• Added support for GLFW Window Attribute GLFW_HOVERED
• Fixed #6: emscripten_glfw_make_canvas_resizable does not clean up properly.
• Fixed an issue with opacity: when using opacity, the handle is not working unless its z-index is higher than the canvas z-index

Pushed WebGPU Shader Toy update: v2024.07.21

• In automatic layout mode, added the ability to resize the two panes easily by clicking and dragging the space between them. Double-clicking will revert to an even split.

Pushed WebGPU Shader Toy update: v2024.07.19

• Added the ability to duplicate a shader (right-click on its name for a popup, or select the option in the Shader menu)
• Handle error cases in dialogs (empty name, duplicate name, invalid size, etc…)
• Added Ctrl + A and Ctrl + E shortcuts for beginning / end of line shortcuts (Select All is now Ctrl + Shift + A)</li>

Pushed WebGPU Shader Toy update: v2024.07.15

• Tweaked keyboard navigation: make sure that the editor always has preference
• Limit the size of the error message window
• Tweaked version number to make it more readable

Pushed WebGPU Shader Toy update: v2024.07.14

• Added the ability to take a screenshot
  • : take a screenshot instantly (use the previous/default format)
  • : open the menu to select a format and a filename
• Added the ability to enable/disable shader rendering ()

I am very happy to announce the release of WebGPU Shader Toy, a tool for experimenting with WebGPU fragment shaders and the WebGPU Shading Language (WGSL)

• Here is the product page
• Since this tool runs in your browser, you can try it

Released emscripten-glfw 3.4.0.20240625 with the following release notes:

• Implemented workaround for #4: Using Super + “Key” on macOS results in “Key” not being released. Due to the broken state of javascript handling the Super/Meta key, there is no good solution. The workaround implemented, releases all keys when Super is released. Although not a perfect solution, it guarantees that the state is eventually consistent:
  • if “Key” was released while “Super” was held, then when “Super” gets released, “Key” is released (later than when actually released, final state is consistent: “Key” in Release state)
  • if “Key” is still held when “Super” is released, “Key” is released when “Super” gets released, but immediately gets a down event (Up/Down event, final state is consistent”: “Key” in Pressed state)

Released re-mock update: v1.6.0

• Added support for device_categories in info.lua which was added as a new requirement with Reason 13
• Deprecated automatic support for std::filesystem::path in fmt due to UTF8: use path.u8string() instead

Released RE Edit update: 1.6.4:

• Added support for device_categories which was added as a new requirement to Reason 13

Released re-cmake update: v1.7.2

• Updated re-mock version (added support for device_categories)

Released emscripten-glfw 3.4.0.20240617 with the following release notes:

• Fixed #3: glfwGetKey must return one of GLFW_PRESS or GLFW_RELEASE

Released emscripten-glfw 3.4.0.20240616 with the following release notes:

• Implemented glfwGetClipboardString. Note that due to the async (and restrictive) nature of the navigator.clipboard.readText call, this synchronous API returns whatever was set via a previous call to glfwSetClipboardString and ignores the external clipboard entirely.

Released emscripten-glfw 3.4.0.20240601 with the following release notes:

• Fixed #2: Dynamically changing HiDPI awareness does not trigger content callback

Released emscripten-glfw 3.4.0.20240514 with the following release notes:

• Implemented glfwSetClipboardString

Released emscripten-glfw 3.4.0.20240501 with the following release notes:

• Fixed issue when calling glfwGetWindowContentScale with nullptr
• Renamed javascript api/impl since these names are not unique to avoid potential conflicts
• Added glfw3native.h to GLFW. Although not used (at this moment) by this implementation, this allows calling code to include it if necessary since it is part of a normal GLFW installation.

Released emscripten-glfw 3.4.0.20240318 with the following release notes:

• Fixed joystick/gamepad code that was improperly mapping GLFW_GAMEPAD_AXIS_LEFT_TRIGGER GLFW_GAMEPAD_AXIS_RIGHT_TRIGGER, GLFW_GAMEPAD_BUTTON_LEFT_THUMB and GLFW_GAMEPAD_BUTTON_RIGHT_THUMB
• GLFW_GAMEPAD_AXIS_LEFT_TRIGGER and GLFW_GAMEPAD_AXIS_RIGHT_TRIGGER are now properly represented as an analog value in the range [-1.0, +1.0]
• Please note the change in version numbering which from now on will be tied to the GLFW version implemented + date of release of this port to avoid confusion

I released emscripten-glfw 1.1.0 which implements GLFW 3.4 APIs:

• Upgraded to GLFW 3.4
• GLFW 3.4 features implemented
  • glfwGetPlatform and glfwPlatformSupported uses the GLFW_PLATFORM_EMSCRIPTEN constant defined in emscripten-glfw3.h (officially reserved value is 0x00060006)
  • glfwInitHint supports the new hint GLFW_PLATFORM
  • Supports all 10 cursors
  • Implemented glfwGetWindowTitle
  • Use GLFW_SCALE_FRAMEBUFFER to enable (resp. disable) Hi DPI support
  • Changed the functions that can report GLFW_FEATURE_UNAVAILABLE failure to report this error instead of a warning
• GLFW 3.4 features not implemented
  • GLFW_MOUSE_PASSTHROUGH is not supported
  • GLFW_CURSOR_CAPTURED cursor input mode is not supported (not possible in a browser context)
  • glfwInitAllocator is implemented as noop (could be supported for the C++ part only if there is demand, not javascript)
  • GLFW_POSITION_X and GLFW_POSITION_Y are not supported (same as glfwSetWindowPos)
  • GLFW_ANGLE_PLATFORM_TYPE is not supported (no direct access in browser, but implementation is most likely using it anyway)
• Since GLFW 3.4 introduces a proper constant to handle Hi DPI Awareness (GLFW_SCALE_FRAMEBUFFER), the prior constant used by this port (GLFW_SCALE_TO_MONITOR) is still accepted, but it is now deprecated. In addition, due to the fact that GLFW_SCALE_FRAMEBUFFER defaults to GLFW_TRUE, this port is now Hi DPI aware by default and needs to be explicitly turned off (glfwWindowHint(GLFW_SCALE_FRAMEBUFFER, GLFW_FALSE)) if this is the desired behavior.

Note: These changes are available in emscripten 3.1.56 (released on 2024/03/14) via the contrib port contrib.glfw3

I released emscripten-glfw 1.0.5 with a critical bug fix:

• Fixed memory corruption with joystick

Note: These changes are available in emscripten 3.1.55 (released on 2024/03/01) via the contrib port contrib.glfw3

Released 1.6.3:

• Fixed issue with contrast not being saved

I am very happy to announce the 1.0 release of my new free and open source project emscripten-glfw which is a port of glfw written in C++ for the web/webassembly platform.

Check out the live demo.

Just released a new version of my Roku screensaver B.P.O.D.: 1.1.0

• Added “Title” settings to control when the title of the image gets displayed

New re-cmake update: v1.7.1

• Fixes issue locating RE2DRender and RE2DPreview after SDK 4.4.0 final release

Just released a new re-mock updated: v1.5.0

• Upgraded SDK to 4.4.0

Note that JukeboxTypes.h has some new defines but it is not really affecting the project…

A new release is available: 7.0.0

• Migrated Jamba to use VST3 SDK 3.7.8 (release notes). Please check other release notes to see what has changed since 3.7.5 (last Jamba supported version).
• As explained in issue #16, Jamba is no longer supporting VST2
• Added a way to patch the SDK by defining the CMake cache string JAMBA_VST3SDK_PATCH_DIR (Jamba uses it on Windows/DLL build to fix an issue with win32resourcestream.cpp, but you can also use it for your own purposes): by defining this variable, 2 things happen
  • Jamba copies the SDK inside the build folder
  • Jamba copies all the files under ${JAMBA_VST3SDK_PATCH_DIR} on top of this copy while never modifying a local version of the SDK

A new version of SAM-SPL 64 has been released: v1.5.0:

• Added support for MP3, Flag, Ogg Vorbis (in addition to WAV and AIFF)
• Added error message when issue with loading file
• Fixed sound issues with Bitwig Studio
• Fixed drag and drop bug
