This question used to contain a mistake in the code, so I had to debug and reformat it. This is the correct version.
Why I made it
A friend and I wanted to make a lightweight browser, since our Raspberry Pi Zero 2 W couldn’t handle popular browsers like Chromium. We also wanted to bring back our own version of Clippit, aka Clippy, for those who remember the annoying helper in Microsoft Word from the early 2000s. We named our version Mano, and the browser itself is titled ManoSearch.
What it does
When you run the script, an ASCII window fills your screen with my friend’s version of Clippy in the top-right corner. You can:
- Open URLs by entering
+then the URL you want. - Navigate tabs on top of the screen by entering the tab number you want.
- Scroll websites with
uandd(you can also get back to the top by usingU) - Open links in new tabs by entering them (links look like
[a b c]and can be entered partially as long as it contains a[or a]) - Closing a tab by entering
x - Enter
videoorvidto useytdlpto download a video from the current website and save it undervid.mp4 - Delete a previousely downloaded video by entering
rm vid - Rename a video to be able to download some more using
mv vid - Find all occurences of something by entering
lookup Find this and highlight it
It does not support javascript or input interaction. To mimic how annoying the original Clippy was, whenever Mano speaks, the current tab’s content disappears. Occasionally, a chicken crosses the browser—you just have to wait for it to cross the screen before you get to continue. And no, you cannot get rid of either of them :)
Problems
Two main issues concern me:
- Sometimes, when a link opens in a new tab, links clicked there search on the original tab instead. It only searches on the last manually opened tab (enter
+), not via link (enter[Link name here]). - I’d love to add javascript support, but I don’t know how.
