• cl-webkit - WebKitGTK+ binding for Common Lisp

** About 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.

** API overview 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.

** Dependencies

• 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]

** Installation Assuming you have [Quicklisp] installed, do

1. Clone to =~/common-lisp/quicklisp/local-projects/cl-webkit=

2. lisp

3. (ql:quickload :cl-webkit2)

*** Testing To run tests, you need to additionally install [[https://github.com/hawkir/calispel][Calispel]], [[https://github.com/Shinmera/float-features][float-features]] and [[https://github.com/lispci/fiveam][FiveAM]] (all of these are available via Quicklisp). After that, simply running =(asdf:test-system :cl-webkit2)= should be enough.

• Support libwebkit2gtk-4.1.
• Rename starred functions to non-starred for consistency:
  • =webkit-web-view-can-execute-editing-command*= -> =webkit-web-view-can-execute-editing-command=.
  • =webkit-web-view-send-message-to-page*= -> =webkit-web-view-send-message-to-page= *** 3.2.0
• Add =webkit-web-view-can-execute-editing-command*= for easier execution command checking. *** 3.1.1
• Export =webkit-web-view-execute-editing-command= properly. *** 3.1.0 Additions:
• =webkit-web-view-send-message-to-page*= to send =WebKitUserMesssages= in a nicer Lispy way.

• Bind all the subtypes of =WebKitPermissionRequest=.
• Bindings for:
  • =webkit_user_content_manager_remove_script=
  • =webkit_user_content_manager_remove_style_sheet=
• New =g-variant-get-maybe-string=: checks =GVariant= for nullness and returns a contained string if possible.
• 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. *** 3.0.0
• 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 [[https://webkitgtk.org/reference/jsc-glib/2.32.1/JSCValue.html][JSCValue]] it was transformed from.
• Add tests (webkit2/tests/ subdirectory and =cl-webkit2/tests= system), mostly for JS evaluation results.
