Cyclic Expand / Hippie completion for vscode

I ripped this from this unmaintained package: https://github.com/msafi/xvsc/tree/master/simpleAutocomplete

The differences with this version are as follows:

• the completion is case sensitive
• it's possible to cycle backwards (thanks @stagas)

Usage

Add this to your keybindings.json file:

{
  "key":     "alt+/",
  "command": "cyclicExpand.next"
},
{
  "key": "shift+alt+/",
  "command": "cyclicExpand.prev"
}

Here's how the cycling works:

Given this text:

mist
milk
m<CURSOR_HERE>
mild
mystery

Cycling next will march in a "ripple" fashion, as such:

m > milk > mild > mist > mystery

Cycling backwards is only available after having advanced in the ripple completion, like this:

# If you stopped cycling at mystery
mystery > mist > mild > milk > m

# If you stopped cycling at mist
mist > mild > milk > m

# If you stopped cycling at mild
mild > milk > m

# If you stopped cycling at milk
milk > m

# If you haven't cycled since moving your cursor
m --> nothing happens

Improvements

1 - Cycling in a "ripple" fashion is a bit odd. In the future, I'd like to mimic JetBrain's hippy completion which goes like this:

Given this text:

mist
milk
m<CURSOR_HERE>
mild
mystery

Cycling next:

m > milk > mist

Cycling prev (next reversed):

m > mild > mystery

2 - The test setup is in a half broken state. See this for later upgrades.

See:

The vscode module had been the default way of running extension integration tests and is being superseded by @vscode/test-electron.

3 - I should bundle the assets

Right now, I publish including my node_modules. Doing otherwise will cause the extension to fail loading (because escape-string-regexp is absent). let's say it's less than ideal!

Development

To work on the extension, go to the "Run and Debug" menu, then run "Launch Extension".
