hafas - Commandline Public Transit Routing Interface

hafas is a commandline client and Perl module for HAFAS pulic transit routing interfaces. See the Travel::Routing::DE::HAFAS homepage for details.

Installation

You have three installation options:

• Installing the latest release from CPAN
• Installation from source
• Using a Docker image

Except for Docker, hafas is available in your PATH after installation. You can run hafas --version to verify this. Documentation is available via man hafas.

Installation from CPAN

Travel::Routing::DE::HAFAS releases are published on the Comprehensive Perl Archive Network (CPAN) and can be installed using standard Perl module tools such as cpanminus.

Before proceeding, ensure that you have standard build tools (i.e. make, pkg-config and a C compiler) installed. You will also need the following libraries with development headers:

• libssl
• zlib

Now, use a tool of your choice to install the module. Minimum working example:

cpanm Travel::Routing::DE::HAFAS

If you run this as root, it will install script and module to /usr/local by default.

Installation from Source

In this variant, you must ensure availability of dependencies by yourself. You may use carton or cpanminus with the provided Build.PL, Module::Build's installdeps command, or rely on the Perl modules packaged by your distribution.

To check whether dependencies are satisfied, run:

perl Build.PL

If it complains about "... is not installed" or "ERRORS/WARNINGS FOUND IN PREREQUISITES", it is missing dependencies.

Once all dependencies are satisfied, use Module::Build to build, test and install the module. Testing is optional -- you may skip the "Build test" step if you like.

If you downloaded a release tarball, proceed as follows:

./Build
./Build test
sudo ./Build install

If you are using the Git repository, use the following commands:

./Build
./Build manifest
./Build test
sudo ./Build install

If you do not have superuser rights or do not want to perform a system-wide installation, you may leave out Build install and use hafas from the current working directory.

With carton:

carton exec hafas --version

Otherwise (also works with carton):

perl -Ilocal/lib/perl5 -Ilib bin/hafas --version

Running hafas-m via Docker

A hafas image is available on Docker Hub. It is intended for testing purposes: due to the latencies involved in spawning a container for each hafas invocation, it is less convenient for day-to-day usage.

Installation:

docker pull derfnull/hafas:latest

Use it by prefixing hafas commands with docker run --rm derfnull/hafas:latest, like so:

docker run --rm derfnull/hafas:latest --version

Documentation is not available in this image. Please refer to the online hafas manual instead.
