Adopt SnippetString API

[jrieken]

With the December release VS Code will have real API to define a CompletionItem that is inserted as snippet, for details see microsoft/vscode#3210.

In short, we now support a subset of the more common TextMate syntax: $1, $2 etc define tabstops, ${1:value} and ${2:this is${3:nested}} placeholders, and $0 is for the final tabstop.

The API for this is contained in a new type SnippetString. It can be used as the insertText of a CompletionItem.

During a transition phase we will still support the internal, unspecified snippet syntax your extension is using but eventually remove it (roughly 2 or 3 milestones from now).

Hey @jrieken, seems the extension @shardulm94 wants to created (from microsoft/vscode#3210) would be a wonderful replacement for this one anyway. I'll see what he comes up with and may be able to just deprecate this one.

Thanks for the heads up.

@HookyQR I have not been able to find time to work on my project due to college. In this time, I feel https://github.com/joelday/vscode-docthis has matured a lot, and seems like he has a few things planned after this API change. You should definitely check it out.

@joelday ... tag, you're it! 😉

@HookyQR @shardulm94 I'm on it!

[jrieken]

Any update on this? We kind of wanna go ahead with deprecating the old snippet syntax

[joelday]

@jrieken I'm now using the snippet API for https://github.com/joelday/vscode-docthis. I'm under the impression that @shardulm94 Isn't inclined to go forward with this project.

@joelday, does your extension provide everything that's available in here?
