.inputField(): More input control (erase begining of input, erase end of input, move to next/previous word) about terminal-kit HOT 10 CLOSED

BTW you should not edit the screen directly because it would do it behind the back of the inputField.

If I understand correctly, this is trivial to implement, I will look into it tomorrow.

Another thing I'm thinking about where this would be useful is in implementing the standard terminal ability to hold CTRL and press the left and right arrow keys to move the cursor by words and logical segments. If there were just a way to get and set the cursor offset (single number, not coordinates) in the input relative to the beginning of the text then all of this would be easy to implement. The trick is just making sure that the offset takes into account multi-line inputs.

@jwarkentin Ctrl-left, Ctrl-right, Ctrl-U and Ctrl-K are now implemented as of v1.2.0.

As far as I can tell, the current implementation of the Ctrl-U and Ctrl-K behavior updates the cursor position and the inputField's value, but it doesn't actually erase any characters from the terminal. Is this a bug or is the screen-updating supposed to happen outside of the inputField's redraw() routine?

@samizdatco It works on all terminal that I tested. What is your terminal/OS?

from terminal-kit.

I'm using Terminal.app on Mac OS 10.11 (though note that the same behavior is seen in iTerm2 as well).

Here's my test script:

var term = require( 'terminal-kit' ).terminal
term('>')
term.inputField(function(err, input){
    term.processExit(0)
})

And here's what I see after entering some text and then typing Ctrl-U:

Thanks for reporting, indeed there was redraw issue depending on some options (or absence of options). It should be fixed now! ;)

from terminal-kit.

Yes! It's working great now. Thanks so much!

I also added a couple of other deletion keybindings that are common to most readline-powered command line tools here:
Ctrl-W: delete previous word
Alt-D: delete next word

Do these seem more or less correct to you?

This is cherry-picked, and it landed on v1.9.0, thanks! ;)
