# hafas-m - Commandline Public Transit Departure Monitor
hafas-m is a commandline client and Perl module for HAFAS public transit
departure interfaces. It provides native support for the following
interfaces, and can also be pointed to URLs not listed here.
* [Deutsche Bahn](https://reiseauskunft.bahn.de/bin/bhftafel.exe)
* [Nahverkehrsverbund Schleswig-Holstein](https://nah.sh.hafas.de/bin/stboard.exe)
* [Nahverkehrsservice Sachsen-Anhalt](https://reiseauskunft.insa.de/bin/stboard.exe)
* [Nordhessischer VerkehrsVerbund](https://auskunft.nvv.de/auskunft/bin/jp/stboard.exe)
* [Rostocker Straßenbahn AG](https://fahrplan.rsag-online.de/hafas/stboard.exe)
* [Verkehrsverbund Berlin-Brandenburg](https://fahrinfo.vbb.de/bin/stboard.exe)
* [Verkehrsverbund Bremen/Niedersachsen](https://fahrplaner.vbn.de/hafas/stboard.exe)
* [Österreichische Bundesbahnen](https://fahrplan.oebb.at/bin/stboard.exe)
See the [Travel::Status::DE::DeutscheBahn
homepage](https://finalrewind.org/projects/Travel-Status-DE-DeutscheBahn) and
[hafas-m manual](https://man.finalrewind.org/1/hafas-m) for details.
## Installation
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, __hafas-m__ is available in your PATH after installation.
You can run `hafas-m --version` to verify this. Documentation is available via
`man hafas-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 not covered by its quality assurance
process.
To install the latest release, run:
```
wget https://lib.finalrewind.org/deb/libtravel-status-de-deutschebahn-perl_latest_all.deb
sudo dpkg -i libtravel-status-de-deutschebahn-perl_latest_all.deb
sudo apt --fix-broken install
rm libtravel-status-de-deutschebahn-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-deutschebahn-perl_dev_all.deb
sudo dpkg -i libtravel-status-de-deutschebahn-perl_dev_all.deb
sudo apt --fix-broken install
rm libtravel-status-de-deutschebahn-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::DeutscheBahn installation.
Uninstallation works as usual:
```
sudo apt remove libtravel-status-de-deutschebahn-perl
```
### Installation from CPAN
Travel::Status::DE::DeutscheBahn 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::DeutscheBahn
```
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
```
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-m** from the
current working directory.
With carton:
```
carton exec hafas-m --version
```
Otherwise (also works with carton):
```
perl -Ilocal/lib/perl5 -Ilib bin/hafas-m --version
```
### Running hafas-m via Docker
A hafas-m image is available on Docker Hub. It is intended for testing
purposes: due to the latencies involved in spawning a container for each
hafas-m invocation, it is less convenient for day-to-day usage.
Installation:
```
docker pull derfnull/hafas-m:latest
```
Use it by prefixing hafas-m commands with `docker run --rm
derfnull/hafas-m:latest`, like so:
```
docker run --rm derfnull/hafas-m:latest --version
```
Documentation is not available in this image. Please refer to the
[online hafas-m manual](https://man.finalrewind.org/1/hafas-m/) instead.
