• zsh allows undo last editing command, so that we can undo the effects of CTRL-W for example

• [EDIT] zsh allows to skip duplicates when navigating history (they're saved in history but only each unique instance is recalled when navigating with up arrow)

CTRL-C is used to abort a line/the program. It would be nice if the ESC-key can also be used in this context. But then readLine should return something else then a bool.

One should be able to use the ESC-key to cancel some user input (soft abort) and CTRL-C to abort the program (hard abort).

Hello, it seems this is not possible at the moment, but that it could be allowed by enabling the injection of custom procs to the Noise.procs list. Let me know what you think, thank you.

First of all, good work on this library! One thing confuses me a little bit though: do you really support editing multiple lines?

I tried:

• Entering text till the end of the line, and when the line wraps the text gets garbled
• Pressing ENTER or SHIFT+ENTER accepts input

Is there any way to edit multiple lines? How?

RIGHT_ARROW_KEY works but not ALT + RIGHT_ARROW_KEY which prints [C instead of move cursor right by one word

could shift SHIFT + RIGHT_ARROW_KEY be used maybe?

in bash, python3 and pretty much all repls, ctrl C doesn't run the current entered line but also doesn't exit the repl, whereas ctrl D (when there is no input written) exits the REPL.

here, both ctrl C and ctrl D exit the REPL. How can we at least distinguish whether ctrl C or ctrl D was entered?

example

bash-3.2$ asdf # control C was entered here
bash-3.2$ asdf # control D was entered here
bash-3.2$ exit

zsh allows the very useful history recall based on what you already started typing so that:
abc will recall abcfoo but not bar if abcfoo and bar are in history, see https://unix.stackexchange.com/questions/97843/how-can-i-search-history-with-text-already-entered-at-the-prompt-in-zsh

is there a way to do this in nim-noise? if not, it'd be great!

Hello, in Emacs, but also GNU readline, bash and other shell the case editing behavior is different than used here. In Emacs when you press one of these keys inside a word, only the characters up to the end of the word are affected, so if | is the cursor, and you are in this situation foo|bar and then you press M-C in the shell you get fooBar, with noise instead you get Foobar. This is the same for the other case commands.

I think there should be a compiler option to enable classic behavior.

In my code I use the same order as the Readme:

• Load history
• Set prompt
• Set completion hook
• Start loop to read lines

When I hit TAB (as the first character) on a line I get a runtime error.
