Allow "Partial" Import Code Snippet

[jjangga0214]

Feature request

What problem does this feature solve?

Import Code Snippet feature is cool. Users don't have to copy and paste code from the original file. It does not require "syncing" when the the referred file is modified.

However, in most cases, I'd want to import just a few lines from the source code. Because the entire file would be obviously "long" in many cases, and contains "unnecessary" content.

What does the proposed API look like?

Let's assume I want to only import from line 5 to 10.

Proposal 1

<<< [5-10] @/filepath

Proposal 2

<<< @/filepath [5-10] 

Proposal 3

<<< @/filepath[5-10] 

Are you willing to work on this yourself?

Not sure right now.
