Delta Chat plugin for libpurple
Delta Chat is an instant messaging application based on email - which is to say, SMTP+IMAP.
- A mature core library
- A mature Android application
- An experimental iOS application
- An electron desktop application
This project is a libpurple
plugin that wraps
deltachat-core, allowing a number of existing desktop and
mobile clients to send and receive IMs over SMTP+IMAP. It may be useful for
Linux-based mobile devices, for
GUI desktop usage without an Electron dependency, or console desktop usage.
Current status is probably best described as "skunkworks", although connecting to an account and sending / receiving text and image messages should work reliably in pidgin. Chatty supports text messages, and can be coaxed into using this plugin, but there's a long way to go with that yet.
A big refactoring to use "proper" purple IM structures is necessary to make further progress, I think.
I also need to implement support for the buddy list.
We currrently build against deltachat v1.50.0. You'll need to build and install
deltachat-ffi separately and ensure that it's available via
deltachat to install.
There are some licensing issues at present, so you shouldn't build this plugin.
deltachat-core-rust uses a vendored openssl 1, unconditionally links it, and
purple-plugin-delta is GPLv3 without the OpenSSL exemption
libpurple itself is GPLv2 without the OpenSSL exemption.
There's no point to
purple-plugin-delta adding the OpenSSL exemption because
libpurple lacks it, and in any event, it will be unnecessary with the next
major version of OpenSSL. So, time should resolve this for us one way or another.
The easiest way to use this is to copy the
libdelta.so file into
~/.purple/plugins. When running pidgin, you'll now have the option to add
a "Delta Chat" account.
If it doesn't show up, chances are pidgin can't find the various shared
libraries the .so depends on. You can run
to confirm. I'll document fixing this after the build and install system is
At present, the "Username" and "Password" account fields correspond to email address and password, respectively. Many important settings also show up on the "Advanced" tab - if left blank, the plugin will attempt to automatically detect the correct values, but you may need to fill some of them in manually to get the connection to work.
Run pidgin with
--debug to see interesting output.
