Partial completion

[mlopes]

Hi,

I would like to suggest the following enhancement to the auto-completion process.
When there's a multi word completion suggestion, based on history, frequently one needs part of the command and more often than not, the end part needs to be replaced.

My suggestion consists in adding an extra auto-complete shortcut that only completes until the next white space:

Ex:

when typing "l" I get the following suggestion:

ls -lha /var/www

pressing the new shortcut key would produce "ls" and keep the remainder as a suggestion, pressing it again wound produce "ls -lha" and keep the remainder as a suggestion.

Cheers,
Marco Lopes

Sounds interesting, but also difficult to implement properly, especially considering you could mean something else. What if you actually wanted -la, and not -lha, or less, not ls?

[mlopes]

Currently, with ctrl-f or right cursor it would complete immediately to "ls -lha /var/www", so when I mean "less" I'll type "le", it will suggest "less" and then press right cursor. My suggestions is to have the exact same rules that apply to the ctrl-f/right cursor completion, but have another shortcut that only completes 1 word at the time, thus allowing to repeat commands with slight differences.

Let's assume the part inside the [] is the suggested part that is still not completed
let's says that I typed "gi", and that will cause ctrl-f to do the following:
gi[t push -u origin feature1]
press ctrl-f (this is what already happens)
git push -u origin feature1

Pressing this new shortcut (let's for examples sake use ctrl-w):
pressing ctrl-w once:
git [push -u origin feature1]
twice:
git push [-u origin feature1]
three times:
git push -u [origin feature1]

And so on.

At any time, pressing ctrl-f would have the exact same effect it does now

Cheers,

You can press ALT - Right Arrow for partial completions.

As siteshwar says, this is already available!

Thanks, but with fish 2.0.0 installed from homebrew on iTerm ALT-right arrow only produces this output [1;9C

EDIT: Just found out the fix for this, on iTerm, go to preferences->profiles->keys and set alt-right arrow to send the following hex codes: 0x1b 0x1b 0x5b 0x43

[ridiculousfish]

Maybe we can support iTerm's default key bindings.

if @mlopes means iTerm2, maybe the better configuration is to have opt-right mapped to opt-f, and opt-left to opt-b

23ba7b5 adds support for iTerm2's default escapes (opt-right-arrow and opt-left-arrow). Thanks for reporting this!
