👍

[katcipis]

I would love to start to see at least one full integration test for this kind of thing. The internal tests that are developed are quite hard to understand (at least to someone as limited as me ).

Besides that, LGTM

[i4ki]

@katcipis by full integrated test you mean adding tests in the interpreter (internal/sh) also?

[katcipis]

@tiago4orion actually I was even thinking on testing through the public sh API (the same one we used on klb tests). Less likely to break and gives a code example of what is being done/fixed :-)

[vitorarins]

@tiago4orion is this PR still relevant? Can we merge?

[i4ki]

missing some tests...

[i4ki]

tests are too cryptic.. I'll improve that soon

[katcipis]

This is a nice refactoring. You sir are a gentleman:

[katcipis]

@tiago4orion this will sound a little repetitive with what @vitorarins said, but can we merge this ? =P If it is important we can add better tests later =) (at least it does not break anything and the problem seems serious)
