cl-webkit is a binding to [WebKitGTK+] for Common Lisp, currently targeting WebKit version 2. The WebKitGTK+ library adds web browsing capabilities to an application, leveraging the full power of the WebKit browsing engine.

The cl-webkit API closely follows the WebKit2 API, with the exception that class based interfaces are preferred over functional interfaces in cases where both are provided.

That is, *_{new,get,set} methods are excluded in favour of make-instance and slot accessors wherever possible.

For documentation on how to use the WebKit2 API, please refer to the C API documentation.

Backwards compatibility (with older WebKit2 API versions) is not a priority. The binding targets the latest version of Webkit2Gtk+ available on mainstream distributions.

• A working installation of WebKit2GTK+ (whichever package provides libwebkit2gtk-4.0.so, e.g., libwebkit2gtk on Debian).
• A [CFFI] compatible Common Lisp implementation. The package is developed using [SBCL] but should work on any implementation that supports CFFI.
• A recent checkout of [cl-cffi-gtk]

Assuming you have [Quicklisp] installed, do

1. Clone to ~/common-lisp/quicklisp/local-projects/cl-webkit
2. > lisp
3. > (ql:quickload :cl-webkit2)

To run tests, you need to additionally install Calispel, float-features and FiveAM (all of these are available via Quicklisp). After that, simply running (asdf:test-system :cl-webkit2) should be enough.

  • webkit-web-view-send-message-to-page* -> webkit-web-view-send-message-to-page

• Add webkit-web-view-can-execute-editing-command* for easier execution command checking.

• Export webkit-web-view-execute-editing-command properly.

Additions:

• webkit-web-view-send-message-to-page* to send WebKitUserMesssages in a nicer Lispy way.
• More WebKitSettings settings.
• Bind all the subtypes of WebKitPermissionRequest.
• Bindings for:

• The WebKitURISchemeRequest callbacks run on separate thread now.
• make-jsc-function should return the original JSCValue as a second value.

Minor API-breaking changes:

• webkit-web-context-register-uri-scheme-callback now has one less optional arguments.

Bug Fixes:

• Fix mistyped JSC-related exports.
• Use :string type instead of :pointer for WebKitUserMessage names.
• webkit2.uri-response is not loaded in cl-webkit.asd.

• Make webkit-web-view-evaluate-javascript process the returned values and turn them into the matching Lisp values (see jsc-value-to-lisp docstring for transformation rules).
• The callback to the webkit-web-view-evaluate-javascript now accepts two required arguments – the Lispy data, transformed from the results of code evaluation, and an original JSCValue it was transformed from.
• Add tests (webkit2/tests/ subdirectory and cl-webkit2/tests system), mostly for JS evaluation results.
