asn1grep.py: a script for finding a datatype in ASN.1 files

asn1grep parses our ASN.1 spec files, then searches for a given datatype by recursively descending through the LTE-RRC types we care about. it then prints out each result as a "path" through the highly nested datatypes.

Setup:

1. python -m venv .venv && . .venv/bin/activate
2. pip install -r requirements.txt

Usage:

» python asn1grep.py IMSI                                  
searching for IMSI
PCCH-Message [message [message.c1 [c1 [c1.paging [paging [pagingRecordList[0] [ [ue-Identity [ue-Identity.imsi [IMSI]]]]]]]]]]
