We might add that BRLTTY is also completely unaware of what the application (that happens to be reading from the terminal) is going to do with the input, if anything. Yet this unawareness does not prevent BRLTTY from sending pasted text or cursor routing key sequences to the terminal. BRLTTYcompletely disregards that 1) The receiving application does not necessarily react to the sent data in any desirable way, 2) BRLTTY does not even know the terminal type, so when sending cursor key escape sequences, it might well send wrong escape sequences for the terminal. Often confusion, and even data loss has happened due to BRLTTY's behaviour. One of my NetHack characters died because I accidentally pressed a cursor routing button during gameplay. Isn't that serious? But in practice, we find BRLTTY's cursor routing and clipboard functionality so useful, that we tolerate these shortcomings. And this leads to: > so bracketed paste can't be supported. The question is about at what cost. BRLTTY could have a toggle for controlling sending the bracketed paste sequence to the terminal. Or BRLTTY could have a separate PASTE_BRACKETED command. When bracketing is enabled, BRLTTY would bracket the pasted text with the escape sequences used by Xterm (and by the way all other terminal emulators which support this feature). This, of course, might break if used in a wrong context, but this is in no way different from the current situation where the user might paste text in a wrong context. Would this be beginner friendly? No, it wouldn't. But equally the current behaviour of pasting and cursor routing are not beginner-friendly, especially not for users not used to how text terminals work. Would this be worth testing? I believe so. I believe that implementing this would be kind of a small effort, and removing it (if the feature finds no users) is even easier. Also, this would not affect those people, who do not ever enable the toggle for bracketed paste. -- Aura _______________________________________________ This message was sent via the BRLTTY mailing list.
