Erlang HL7 NIF Parser

Overview

This HL7 parser is an Erlang NIF interface into the C-based hl7parser.

Requirements

You'll need Erlang/OTP R16B to be able to compile and use this parser. You'll also need rebar installed and accessible in your PATH.

Installation

You'll need to retrieve the dependencies and the compile the project. You can do this by running:

 deps

And you can check that everything is working properly by running:

 test

Custom segments

The segment accessors are defined in an Erlang file (src/hl7_segment_def.eon) and are auto-generated by an escript (ehl7_codegen). The code used to encode and decode the segments is already included in the project (see src/ehl7_segment.erl and include/ehl7_segment.hrl). If you need to modify the segment definitions, just remove these files, modify the definition file and run the script like this:

l7_codegen
