Nice idea! How do you think to smplify to one lines arg:

• lines=5:
• lines=2:5
• lines=:5

Yeah I think that's nicer.

And in case only the starting/ending line was defined, should we assume that the user want to copy from line 0/to the end?

Waiting on this change to adopt this library, any estimates of when this will be published?

Also from personal experience using a similar library on this project https://github.com/MionKit/mion.
When importing source code, using line numbers gets very difficult to maintain and requires a review every time the src code gets updated.
it would be very interesting to be able to use a pattern delimiter as an argument so we can insert comments in the src code and extract the code between the delimiters

<!-- automd:file src="./example.ts" code dlimiter="//######myFunction" -->
<!-- /automd -->

This would extract anything between the delimiter // ######myFunction

// file ./example.ts

export const token = '1';

// ######myFunction
export function myFunction() {
   // code here
}
// ######myFunction

This example would only import the src code within the delimiters (myFunction).

willing to work on it after this PR get merged
