okay so bestie, welcome to urxvt-confirm-paste(1) from the RXVT-UNICODE manual — this little page is giving clipboard safety with main character energy ✨.

🎀 NAME 🎀

confirm-paste — ask for confirmation before pasting control characters

🌸 DESCRIPTION 🌸

It displays a confirmation dialog when a paste containing control characters is detected, fr fr. The user can either choose:

• y — paste the string unmodified, exactly as it is 💅
• f — paste a sanitized variant where all control characters are removed 🧼
• n — drop the paste request completely, bye 👋

This is mostly meant as a defense-in-depth mechanism to protect against the common web browser bug of you selecting some text but the browser pasting a completely different text, which has some attack potential. Not the clipboard acting sus 😭.

It can also be useful to prevent you from accidentally pasting large amounts of text. We love a little accidental chaos prevention 🫶.

🔍 DETAILS 🔍

If a string containing unicode control characters (specifically U+0000 .. U+001F currrently) is pasted into the terminal, this extension will ask whether it should be pasted. Strings without control characters get pasted without prompt. Lowkey convenient.

When a sanitized version is pasted (choice f), then contiguous sequences of those control characters will be replaced by a single spaces. Yes bestie, that's the wording — it's iconic in its own way 😭.

The exact detection and sanitization algorithm is subject to change in future versions. So don't get too attached to the details, okay? 🦋
