====== disable bracketed paste in gnu readline ======
In early 2021 GNU Readline, the venerated line editing library used in everything from bash to [[http://docs.frrouting.org/projects/dev-guide/en/latest/vtysh.html|vtysh]], enabled bracketed paste mode by default. This is a significant behavior change, and while it's [[https://lwn.net/Articles/839213/|noted]] that there is a compile time option to change this default, generally you can't tell users to recompile some system library to get a feature back.

The Readline docs themselves are in the typical overly-terse GNU style so this is a quick note on how to restore the old behavior in your readline-using program. There's a function in readline that takes a string and interprets it as if it were present in the user's ''.inputrc'' file; this can be leveraged to disable bracketed paste mode like so:

<code c>
char *disable_bracketed_paste = strdup("set enable-bracketed-paste off");
rl_parse_and_bind(disable_bracketed_paste);
free(disable_bracketed_paste);
