fpwebview - webview in Pascal

14 February 2022

Webview is a "tiny cross-platform webview library for C/C++/Golang to build modern cross-platform GUIs." Webview uses Cocoa/WebKit on macOS, gtk-webkit2 on Linux, and Edge on Windows 10.

There exist various language bindings for Webview, as listed on Webview's Github page. I've just published my Free Pascal binding here.

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

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.

Coincidentally, Toma┼ż Turk recently announced Pharo-WebView.
