Index parsing context variable #169

Closed Rzial closed 3 years ago

Rzial commented 3 years ago

This PR adds an $index variable for array parsing. I've only implemented this for the length parsing option. Also, this PR refactors the way context variables are added to a named parser to make it more easy to extend if needed.

Looks good! Just curious what is your use case for this?

Rzial commented 3 years ago

I have a file that follows the following structure:

To be able to parse objects you need to get the entry on the header. That entry defines the object size and the preceding padding and the entries are ordered on the same way that objects are.

I see that makes sense. Thanks!
