Module: OrigenTesters::Decompiler::Pattern::EnumerableExt

Included in:
OrigenTesters::Decompiler::Pattern
Defined in:
lib/origen_testers/decompiler/pattern/enumerable_ext.rb

Overview

We can't use Ruby's enumerable mix-in directly, as our each method isn't a true implementation, as the mix-in expects. Instead, we'll provide our own enumerable methods as needed that use our own each method.

#each(**options, &block) ⇒ Object Also known as: each_vector

Iterate through the vectors one by one. We'll begin reading the file from the vector start until the regex/block vector_delimiter is met. This delimiter can include multiple lines. Once the delimiter finishes, those lines will be sent to the treetop parser for conversion to an AST. Lastly, the next vector will start where the previous one left off.
