If you are impatient and not interested in the full story, here is the download button for a docker image with hacca in an interactive container based on GNU/Debian bullseye-slim (to be minimalist!):
https://hub.docker.com/r/roccocarbone/hacca
The container is interactive, meaning that the Docker-CLI will talk directly with the h7sh (HL7 shell) included in the image. It can be easily pulled and run using the following commands:
- docker pull roccocarbone/hacca
- docker run -it roccocarbone/hacca
hacca includes a lot of software modules:
-
libhacca - a C library to enable C-written applications to establish, use and release multiple connections with peer applications for the purpose of exchanging HL7 2.x Messages/Segments in a network end-system architecture based on the TCP/IP Protocols accordingly to HL7 international standards.
-
h7sh - The first HL7 2.x shell for Linux Systems, implemented as a clone of the tcsh shell with extensions to add HL7 2.x commands, that include fileutils, connections, HL7 2.x Messages generators and senders over TCP/IPv4 Networks. h7sh may be used as both an interactive tool for talking with medical applications and instruments using HL7 2.x Protocols and an interpreter for the execution of testsuites.
-
hl7c - a tiny-compiler able to convert raw HL7 text files to C data structures (variables/structures/functions) for direct inclusion in C applications. Used mainly for development and a definition of consistent QA test environment.
-
libhl7-files - a tiny C library for working with in memory HL7 files each with its own Messages/Segments. Used mainly for development and a definition of consistent QA test environment.
-
standalone binary programs to play with HL7 2.x Protocols including:
- coreutils (hsegs, hdescribe, hnamespace)
- fileutils (hcat, hc, hdump, htree)
- testing servers (hnulld, hnakd, hackd, hslowd)
- testing clients (hrain, hsndfile)
- testing generators (hgen)
- production servers (hvald, haccad)
- tools (such a general-purpose hacca-plugin loader to build and run complex architetures)
