While I had no trouble getting the parsing part for this to work, I'm
stuck on the generator part. Specifically, I'm stuck on getting the
size into the output.
The goal is a rule that takes a std::vector<byte> and outputs it in such
a way that it is preceded by its size (in a custom encoding) and padded
by zeroes to align on a four byte boundary.
I want to reuse this rule in several other rules and prefer to break it
up into smaller pieces. A minimalistic example of what I have come up
with so far is attached. What I can't seem figure out how to get at and
store the vector's size in pascal_string_size_. There also seem to be
problems with refering to the stored size_ in pascal_string_payload_ and
pascal_string_padding_ that I don't understand.
o Use phoenix::size to extrac the size
o Use karma::embed(*) to feed in the size
o Use local variable to store the size
o Use inherited attribute to pass the size
Full code attached.
