# Greek Reference: Ancient Greek Lexicon & Syntax

This is an ancient Greek lexicon and grammar for Android incorporating open
source texts from the [Perseus Digital Library][perseus].

The app can be downloaded for free from the [Google Play][] and [Amazon][] app
stores. Releases are also available in APK and AAB format on the [GitHub
releases page][releases].

Greek Reference was [recommended][nytimes] by the *New York Times Sunday Book
Review* in 2014 (referenced by its previous title, Ancient Greek Lexicon and
Syntax).

This app is no longer under development. I intend for version 1.16.0 to be the
final release. I'm grateful to everyone who has tried the app and offered
feedback over the years.

This repository is hosted on [git.linskey.org](https://git.linskey.org/greek-reference)
and mirrored on [GitHub](https://github.com/blinskey/greek-reference).

## Building the App

The texts used in this app are contained in a pair of databases called
`lexicon.db` and `syntax.db`. These are generated using a simple Java program,
the [Greek Reference Database Creator][], which is included as a submodule in
this repository. The database files are zipped and placed in this project's
`assets` directory. They must be named `lexicon.zip` and `syntax.zip` in order
to work with the [SQLiteAssetHelper][Android SQLiteAssetHelper] library used to
copy them to the user's device.

If you'd like to assemble a signed APK, place your keystore in the root
directory along with a `release.properties` file containing your keystore
credentials. An example file called `release.properties.sample` is included in
the project.

## Texts
