efa-m is available as perl-travel-status-de-vrr-git in the archlinux User Repository (AUR).
For other distributions, you have four installation options:
.debbuilds for Debian-based distributions
- Installing the latest release from CPAN
- Installation from source
- Using a Docker image
Except for Docker, efa-m is available in your PATH after installation. You
efa-m --version to verify this. Documentation is available via
lib.finalrewind.org/deb provides Debian packages of both development and release versions. Note that these are not part of the official Debian repository and are not covered by its quality assurance process.
To install the latest release, run:
wget https://lib.finalrewind.org/deb/libtravel-status-de-vrr-perl_latest_all.deb sudo dpkg -i libtravel-status-de-vrr-perl_latest_all.deb sudo apt --fix-broken install rm libtravel-status-de-vrr-perl_latest_all.deb
For a (possibly broken) development snapshot of the Git master branch, run:
wget https://lib.finalrewind.org/deb/libtravel-status-de-vrr-perl_dev_all.deb sudo dpkg -i libtravel-status-de-vrr-perl_dev_all.deb sudo apt --fix-broken install rm libtravel-status-de-vrr-perl_dev_all.deb
Note that dpkg, unlike apt, does not automatically install missing
dependencies. If a dependency is not satisfied yet,
dpkg -i will complain
about unmet dependencies and bail out.
apt --fix-broken install installs
these dependencies and also silently finishes the Travel::Status::DE::VRR
Uninstallation works as usual:
sudo apt remove libtravel-status-de-vrr-perl
Travel::Status::DE::VRR releases are published on the Comprehensive Perl
Archive Network (CPAN) and can be installed using standard Perl module tools
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:
Now, use a tool of your choice to install the module. Minimum working example:
If you run this as root, it will install script and module to
In this variant, you must ensure availability of dependencies by yourself.
You may use carton or cpanminus with the provided
installdeps command, or rely on the Perl modules packaged by your distribution.
On Debian 10+, all dependencies are available from the package repository.
To check whether dependencies are satisfied, run:
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 efa-m from the
current working directory.
carton exec efa-m --version
Otherwise (also works with carton):
perl -Ilocal/lib/perl5 -Ilib bin/efa-m --version
An efa-m image is available on Docker Hub. It is intended for testing purposes: due to the latencies involved in spawning a container for each efa-m invocation, it is less convenient for day-to-day usage.
docker pull derfnull/efa-m:latest
Use it by prefixing efa-m commands with
docker run --rm derfnull/efa-m:latest, like so:
docker run --rm derfnull/efa-m:latest --version
Documentation is not available in this image. Please refer to the online efa-m manual instead.
