Djot in the browser

)? 2. How can I get the events string directly from djot.parseEvents(djotContent, { sourcePositions: true }) to the main GTK app, instead of pushing it inside

? Thank you in advance!

By coincidence I also came back to the project I was using WebKitGTK for and used Michael's suggestion of window.webkit.messageHandlers.foo.postMessage() for IPC. It has seemed quite straightforward. In the UI process, I initialise the web view object and the channel: WebKitUserContentManager *manager1; manager1 = webkit_web_view_get_user_content_manager (webView); g_signal_connect (manager1, "script-message-received::channel", G_CALLBACK (handle_script_message), NULL); webkit_user_content_manager_register_script_message_handler (manager1, "channel"); 'handle_script_message' starts like: void handle_script_message (WebKitUserContentManager *manager, WebKitJavascriptResult *js_result, gpointer user_data) { JSCValue *jscValue = webkit_javascript_result_get_js_value (js_result); char *message = jsc_value_to_string (jscValue); It then processes the message send from the web process. In the web process (with "web extensions" code), I can then send the message: void send_js_message (WebKitWebPage *web_page, char *message) { WebKitFrame *frame = webkit_web_page_get_main_frame (web_page); if (!frame) return; JSCContext *jsc = webkit_frame_get_js_context (frame); if (!jsc) return; JSCValue *js_string = jsc_value_new_string (jsc, message); jsc_context_set_value (jsc, "msgString", js_string); JSCValue *jscValue = jsc_context_evaluate (jsc, "window.webkit.messageHandlers.channel.postMessage(msgString);", -1); Before, I had interpolated the string into a JavaScript literal string: asprintf (&js, "window.webkit.messageHandlers.channel.postMessage(`%s`);", message); but this wouldn't work if the mesage contained a backtick (`) character. It seems a bit convoluted that you start with a "page", then get a "frame", before getting a "context" that you can finally execute JavaScript on but I trust that it is this way for a good reason. (This is with the WebKitGTK 4.0 API although I gather there are newer versions now.) I don't know what djot is and don't know how relevant this is to your project.
