Embedded web pages

open <url> shows a live web page inside a tab:

open https://slashdot.org
open page slashdot.org        bare address; https:// is assumed

The page fills the tab body, and the tab is labeled with its page number and domain — 1) slashdot.org. It's a real, live page — click, scroll, type, follow links, log in; the site behaves as it would in a browser, sessions included. Clicking an http(s) link in an agent's rendered output opens a page tab the same way.

Only http and https addresses can be embedded; anything else (javascript:, file:, …) is rejected as invalid. A bare address without the page keyword is treated as a file path — the keyword is what makes slashdot.org a web address.

Viewing, not driving

A page tab only displays the site. The app doesn't script or read the embedded page's contents — whatever you can do inside it, you do by hand. (Programmatic browsing is a different feature: the browser command.) The metadata header's back, forward, and reload buttons are the one exception: they move the embedded page through its own history or reload it, without reading or scripting anything inside it. Double-clicking the address in the metadata header lets you edit it directly; press Enter to load the new address into the same tab, or Escape to cancel.

Many sites send headers refusing to be embedded. When the app runs in its own managed browser window, those framing restrictions are lifted and such sites render anyway; if the app fell back to your system browser at startup, a site that refuses framing may show a blocked or blank area instead.

Page numbers and labels

Each page tab is numbered 1, 2, 3, … — always the smallest free number, so open pages count up from 1 without gaps, and a closed page's number is reused. The strip label combines number and root domain — 1) slashdot.org — with any www. dropped (docs.example.com labels as example.com). The label and the address shown in the metadata header follow you as you navigate inside the embedded page — click through to another page on the same site (or a different one) and both update to match, as long as the app is running in its own managed browser.

Closing

Four routes, same result:

• the tab's × button,
• close while the page tab is active,
• close page <n> from any tab — close page 2 closes page 2 wherever it sits; if there's no page n, that's reported,
• Cmd+W / Ctrl+W, which works even while your focus is inside the embedded page.

Page tabs are live views: not restored by janus --relaunch. To open an address in your OS browser instead, use open external <url> (see Opening files and pages).
