The application routing-instructions converts a textual representation of a route (a list of waypoints, road names and other meta information) to driving instructions. It is distributed as a part of Marble and was formerly called gosmore-instructions. It can generate driving instructions for Gosmore, Routino and Monav (Monav from within Marble only).
The source code is distributed with Marble and can be compiled with cmake. The only dependency is Qt.
git clone git://anongit.kde.org/marble src
cmake -DQTONLY=ON ../src
The binary now lies in src/routing-instructions/routing-instructions and is ready to use. You can also run make install to have it installed. Notice that make install would also build and install Marble. You can do a manual installation instead:
sudo cp src/routing-instructions/routing-instructions /usr/local/bin/
The translation of driving instructions to a language other than english needs translation files. There is a bash script that automates the conversion for you: It downloads the latest translations for all languages supported by KDE, removes uneeded translations to keep the file size small and converts it to Qt's .qm translation format.
cd .. cd src/tools/translations ./routing_instructions_i18n.bash
While downloading and converting files, output like this is generated:

Once finished, a number of routing-instructions_$lang.qm files lie in the current directory. To have the routing-instructions binary find them, they need to be in one of these directories:
A manual installation of these files thus can be done like this:
sudo mkdir -p /usr/share/marble/translations
sudo mv routing-instructions_*.qm /usr/share/marble/translations/
The routing-instructions binary chooses that file for translation whose language code matches the current locale. For example, when using LC_ALL="de_DE.UTF-8" it would try to load routing-instructions_de_DE.qm in one of the above directories. If it's not found, it falls back to routing-instructions_de.qm and finally uses the builtin english language.
A conversion with the output of a previous gosmore routing call in input.txt:
$ routing-instructions input.txt
[ 0 m ] Continue on Hermann-Schneider-Allee. Follow the road for 2.0 km.
[2.0 km] Continue on Daxlander Straße. Follow the road for 1.0 km.
[3.0 km] Turn right into Rheinhafenstraße. Follow the road for 1.5 km.
[4.4 km] Turn left into Durmersheimer Straße. Follow the road for 60 m.
A conversion, overriding the system locale to translate to swedish:
$ LC_ALL="sv" routing-instructions input.txt
[ 0 m ] Fortsätt på Hermann-Schneider-Allee. Följ vägen 2.0 km.
[2.0 km] Fortsätt på Daxlander Straße. Följ vägen 1.0 km.
[3.0 km] Sväng åt höger till Rheinhafenstraße. Följ vägen 1.5 km.
[4.4 km] Sväng åt vänster till Durmersheimer Straße. Följ vägen 60 m.
The conversion can also be called in pipe mode:
$ QUERY_STRING="flat=49.0&flon=8.3&tlat=49.0&tlon=8.35&fastest=1&v=motorcar" \
gosmore gosmore.pak | LC_ALL="pt_BR" routing-instructions
[ 0 m ] Siga em frente em Hermann-Schneider-Allee. Siga a estrada para a 2.0 km.
[2.0 km] Siga em frente em Daxlander Straße. Siga a estrada para a 1.0 km.
[3.0 km] Vire à direita em Rheinhafenstraße. Siga a estrada para a 1.5 km.
[4.4 km] Vire à esquerda em Durmersheimer Straße. Siga a estrada para a 60 m.
The --csv and --dense options are useful to process the generated text further:
$ LC_ALL="zh_TW" routing-instructions --csv input.txt
