Hi all,

I'm pleased to announce fpwebview, the Free Pascal binding for webview, the cross-platform library that links with gtk-webkit2 on Linux, Cocoa/WebKit on macOS and Edge on Windows 10 for building desktop web applications.

Supporting shared library, dylib, DLL and import library files for Linux, macOS and Windows for x86_64 are bundled.

Here's a simple Pascal program that uses fpwebview to implement a web browser.

--- Code: Pascal [+][-]window.onload = function(){var x1 = document.getElementById("main_content_section"); if (x1) { var x = document.getElementsByClassName("geshi");for (var i = 0; i < x.length; i++) { x[i].style.maxHeight='none'; x[i].style.height = Math.min(x[i].clientHeight+15,306)+'px'; x[i].style.resize = "vertical";}};} ---program browser_cli; {$linklib libwebview} uses {$ifdef unix}cthreads,{$endif} math, webview; var w: PWebView; begin { Set math masks. libwebview throws at least one of these from somewhere deep inside. } SetExceptionMask([exInvalidOp, exDenormalized, exZeroDivide, exOverflow, exUnderflow, exPrecision]); writeln('Hello, webview, from Pascal!'); w := webview_create(WebView_DevTools, nil); webview_set_size(w, 1024, 768, WebView_Hint_None); webview_set_title(w, PAnsiChar('WebView Free Pascal')); webview_navigate(w, PAnsiChar('https://www.freepascal.org/')); webview_run(w); webview_destroy(w); writeln('Goodbye, webview.');end.

hi , it is nice to see this big development for lazarus as it was lacking this power , but we try it didnt work could you please see why, or use in windows application

thanks for your efforts

This definitely needs some work: C style pointers? PWebView? Certainly that can be done better.
But it is great effort.

Hi. Assuming you are on Windows, did 'winbuild.bat' fail? That batch file will fail if it cannot invoke fpc.exe to build the program. The location of fpc.exe is set in the %fpcexe% variable in the batch file.

If the failure is something else, please provide more details.

Thanks. For now I am focused on working out bidirectional Pascal-Javascript calls for serverless web app using webview's API or websockets. With more experience using the APIs, a TWebView class wrapping those C-style functions and pointers will come.
