The Intrig Message Decoder
Intrig Xenon provides flexible, powerful and easy to use C++ API for decoding protocol messages.
Originally developed for 3G and 4G programmers and test engineers to decode their complex messages, the xenon decoder has evolved into a general purpose open source tool with an ever expanding protocol support base.
And, using XDDL, you can support your own proprietary message formats.
See xenon in action for yourself using the Intrig online decoder: intrig.com.
1.1. Quick Start
1.1.1. Building on Mac and Linux
From a terminal, issue the following commands:
git clone --recursive https://github.com/intrig/xenon.git cd xenon make make test sudo make install
C++17 or later compiler
Github desktop (for Windows only)
2. Using Xenon
Link with the libxenon.so library, found in
The header files are found in
The XDDL data files are found in
xenon/examples directory for some common uses of the decoder.
If you want to parse your own custom protocols, then the XDDL Reference is a complete reference containing useful examples.
Also, the tools directory contains useful examples, such as
two programs are installed into
2.1. Converting 3GPP asn.1 to XDDL
asnx converts asn.1 PER files to xddl. It handles a subset of the asn.1 spec.
If there any problems please submit an issue.
For 3GPP specs, e.g. 36.331:
Download the latest spec.
Save it to file, e.g. 36.331.txt.
Run: asn-strip -m 36.331.txt > 36.331.asn
Edit 36.331.asn by hand. Some of the lines may have been broken at '-' characters. Just run the following step repeatedly until you fixed the errors.
Run asnx -o TS-36.331.xddl -t 36.331.asn.
Add resulting xddl file to git.
