PReVo

PReVo is an android application containing a portable version of the Reta Vortaro which is an open source dictionary for Esperanto. It contains all of the dictionary data in the package so the application does not need to access the internet.

The official website for the program is here:

http://www.busydoingnothing.co.uk/prevo/

It is also available in the Google play store here:

or with F-Droid here:

Building

This git repo does not include the assets containing the dictionary data. Instead they are built from the ReVo data and the prevodb program which are in git submodules. In order to get these modules, be sure to run the following git command:

git submodule update --init

The prevodb program will be built as part of the app build in order to generate the dictionary data, so you need to make sure you have a compiler for the host machine installed. It will also need the developer packages for expat and glib.

Assuming you have the Android SDK installed correctly, you can build the app either with Android Studio or the command line as follows.

Debug mode:

cd $HOME/prevo
./gradlew assembleDebug

Release mode:

cd $HOME/prevo
./gradlew assembleRelease

You should then have the final package in either app/build/outputs/apk/debug/ or app/build/outputs/apk/release/ depending on the build type.

Building a specific release

The releases are all tagged and signed in the git repo using the following public key:

http://www.busydoingnothing.co.uk/neilroberts.asc

The git submodules were added in version 0.25 so the signed tag contains the commit hash of the dependencies used as well. For older versions, the message for each tag contains the git hashes used for the ReVo sources and the prevodb program. This information can be used to build a copy of a release using exactly the same data. You can see this information for example with:

git show 0.12
