-- This example is meant as a simple starting point to show how to get the information in the simplest available way.
-- Keep in mind that when asking for a `return` after another, only the first one will be output.
-- This method is as good as its JXA counterpart.

-- Google Chrome
tell application "Google Chrome" to return title of active tab of front window
tell application "Google Chrome" to return URL of active tab of front window
-- Google Chrome Canary
tell application "Google Chrome Canary" to return title of active tab of front window
tell application "Google Chrome Canary" to return URL of active tab of front window
-- Chromium
tell application "Chromium" to return title of active tab of front window
tell application "Chromium" to return URL of active tab of front window
-- Safari
tell application "Safari" to return name of front document
tell application "Safari" to return URL of front document
-- Webkit
tell application "Webkit" to return name of front document
tell application "Webkit" to return URL of front document

-- This example will return both the title and URL for the frontmost tab of the active browser, separated by a newline.
-- Keep in mind that to be able to use a variable in `tell application` — via `using terms from` — we’re basically requiring that referenced browser to be available on the system.
-- That means that to use this on "Google Chrome Canary" or "Chromium", "Google Chrome" needs to be installed. Same for other browsers.
-- This method also does not exit with a non-zero exit status when the frontmost application is not a supported browser.
-- For the aforementioned reasons, this method is inferior to its JXA counterpart.
