Custom URL

Register a custom URL scheme.

Syntax

REGISTER PROTOCOL(scheme;method)

Usage

$scheme:="fourd"

REGISTER PROTOCOL($scheme;"MYCALLBACK")

//generate test page with custom hyperlinks

var $file : 4D.File
var $HTML : Text

$file:=Folder(fk resources folder).file("template.html")
$HTML:=$file.getText()
PROCESS 4D TAGS($HTML; $HTML; $scheme)
$file:=Folder(fk resources folder).file("example.html")
$file.setText($HTML)

OPEN URL($file.platformPath)

Getting started on macOS

Launch the url-redirect app once. It is important to do this manually for Finder to recognise the app as as a custom URL handler.

Run the command to register your custom URL scheme.

Getting started on Windows

Launch 4D as Administrator. This is necessary as the command needs to edit some registry keys.

Once registered, you can use the command as a regular user.

On both platforms, the 4D app itself is not the URL handler. Instead, a small helper app with no UI redirects the event using a platform specific messaging system. Your app will receive this notification if it is using the plugin and already runnining.
