See +the [Travel::Status::DE::VRR +homepage](https://finalrewind.org/projects/Travel-Status-DE-VRR/) for details. + +## Installation + +efa-m is available as +[perl-travel-status-de-vrr-git](https://aur.archlinux.org/packages/perl-travel-status-de-vrr-git/) +in the archlinux User Repository (AUR). + +For other distributions, you have four installation options: + +* Nightly `.deb` builds 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 +can run `efa-m --version` to verify this. Documentation is available via +`man efa-m`. + +### Nightly Builds for Debian + +[lib.finalrewind.org/deb](https://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 thus 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-statusg-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 +installation. + +Uninstallation works as usual: + +``` +sudo apt remove libtravel-status-de-vrr-perl +``` + +### Installation from CPAN + +Travel::Status::DE::VRR 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 +* libxml2 +* zlib + +Now, use a tool of your choice to install the module. Minimum working example: + +``` +cpanm Travel::Status::DE::VRR +``` + +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. +On Debian 10+, all dependencies are available from the package repository. + +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 +``` + +### Running efa-m via Docker + +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. + +Installation: + +``` +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](https://man.finalrewind.org/1/efa-m/) instead. |
