PaperPaw is a beta: for testing, and for developers, who can build their own plugins before the release. Expect rough edges.

Plugins, Community plugins

Interlingua

A translation above each line of a book, or after each paragraph, for reading in two languages.

A community plugin, not reviewed: its author published it from GitHub, and the site checked only that it is a working plugin, signed by them.

Interlingua shows a small translation above each line of a book, starting where each sentence begins, and opens it whole on a tap. It can also add a translated paragraph after each paragraph. The text of each paragraph is sent to the service you choose, Google or DeepL, with your own key, kept with your passwords and keys. Nothing is sent until you ask for a chapter to be translated. Translations are kept on the card.

How it works

Interlingua shows a small translation above each line of a book, starting where each sentence on the line starts. Tap the translation, or choose it with the buttons as links are and press Select, to open it whole; again to close it. With Translation after paragraphs, a translated paragraph follows each paragraph instead or as well. Both are in the settings, under Reading. For now the translation is a toy: a few English words in Italian.

Screenshots

A plugin with code runs with full access to the reader. It can read everything on it, your passwords and other secrets included, and use the network. A faulty one can crash the reader; a hostile one can damage it for good. Install it only if you trust who made it, as you would a program on a computer.

Builds

It is built for the Xteink X4, Xteink X4 Pro and Xteink X4 Classic, made for PaperPaw 0.5. A build runs on every PaperPaw of the same plugin interface. When a release raises the interface, a reader on that release waits until the author makes a new build.

On an Xteink X4 the code of all plugins you have turned on shares limited room, about 600 KB if PaperPaw came by an update from CrossPoint. If the reader says there is not enough room, a full flash with the flasher leaves about four times as much: see the help there. Few plugins with code fit on my X4

Its code, open to read

The store shows the source of every plugin with code and keeps a copy, and rebuilds each build from that source with the compiler its fingerprint names, to compare. The file served is always the one its author signed.
