I have the path:

"@foo/*/bars": ["foo/*/bars.ts"]

This is not matching my import of "@foo/beer/bar". Instead, it's matching something like, beer/ba. It should be matching on the beer.
Solution:
In the matchStar function, substr is used. The code implies that substring is what was intended. Substr takes a number of characters. Substring matches two indices; start and end. When switching to substring, the code works as expected.
