-[Wiki](https://wiki.tox.chat/clients/toxygen)
+This hard-forked from the dead https://github.com/toxygen-project/toxygen
+```next_gen``` branch.
+ 
+See ToDo.md to the current ToDo list.
+
+## IRC Weechat
+
+You can have a [weechat](https://github.com/weechat/qweechat)
+console so that you can have IRC and jabber in a window as well as Tox.
+There's a copy of qweechat in https://git.plastiras.org/emdee/qweechat
+that you must install first, which was backported to PyQt5 now to qtpy
+(PyQt5 PyQt6 and PySide2 and PySide6) and integrated into toxygen.
+Follow the normal instructions for adding a ```relay``` to
+[weechat](https://github.com/weechat/weechat)
+```
+/relay add weechat 9000
+/relay start weechat
+```
+or
+```
+weechat -r '/relay add weechat 9000;/relay start weechat'
+```
+and use the Plugins -> Weechat Console to start weechat under Toxygen.
+Then use the File/Connect menu item of the Console to connect to weechat.
+
+Weechat has a Jabber plugin to enable XMPP:
+```
+/python load jabber.el
+/help jabber
+```
+so you can have Tox, IRC and XMPP in the same application! See docs/ToxygenWeechat.md
+
+## Install
+
+To install read the requirements.txt and look at the comments; there
+are things that need installing by hand or decisions to be made
+on supported alternatives.
+
+https://git.plastiras.org/emdee/toxygen_wrapper needs installing as it is a
+dependency. Just download and install it from
+https://git.plastiras.org/emdee/toxygen_wrapper The same with
+https://git.plastiras.org/emdee/qweechat
+
+This is being ported to Qt6 using qtpy https://github.com/spyder-ide/qtpy
+It now runs on PyQt5 and PyQt6, and may run on PySide2 and PySide6 - YMMV.
+You will be able to choose between them by setting the environment variable
+```QT_API``` to one of: ```pyqt5 pyqt6 pyside2 pyside6```.
+It's currently tested mainly on PyQt5.
+
+To install it,  look in the Makefile for the install target and type
+```
+make install
+```
+You should set the PIP_EXE_MSYS and PYTHON_EXE_MSYS variables and it does
+```
+	${PIP_EXE_MSYS} --python ${PYTHON_EXE_MSYS} install \
+		--no-deps \
+		--target ${PREFIX}/lib/python${PYTHON_MINOR}/site-packages/ \
+		--upgrade .
+```
+and installs into PREFIX which is usually /usr/local
+
+## Updates
+
+Up-to-date code is on https://git.plastiras.org/emdee/toxygen
+
+Tox works over Tor, and the c-toxcore library can leak DNS requests
+due to a 6-year old known security issue:
+https://github.com/TokTok/c-toxcore/issues/469 but toxygen looksup
+addresses before calling c-toxcore. This also allows us to use onion
+addresses in the DHTnodes.json file. Still for anonymous communication
+we recommend having a TCP and UDP firewall in place.
+
+Although Tox works with multi-user group chat, there are no checks
+against impersonation of a screen nickname, so you may not be chatting
+with the person you think. For the Toxic client, the (closed) issue is:
+https://github.com/JFreegman/toxic/issues/622#issuecomment-1922116065
+Solving this might best be done with a solution to MultiDevice q.v.
+
+The Tox project does not follow semantic versioning of its main structures
+in C so the project may break the underlying ctypes wrapper at any time;
+it's not possible to use Tox version numbers to tell what the API will be.
+The last git version this code was tested with is
+``1623e3ee5c3a5837a92f959f289fcef18bfa9c959``` of Feb 12 10:06:37 2024.
+In which case you may need to go into the tox.py file in
+https://git.plastiras.org/emdee/toxygen_wrapper to fix it yourself.
+
+## MultiDevice
+
+Work on this project is suspended until the
+[MultiDevice](https://git.plastiras.org/emdee/tox_profile/wiki/MultiDevice-Announcements-POC) problem is solved. Fork me!

+# Toxygen ToDo List
+
+## Bugs
+
+1. There is an agravating bug  where new messages are not put in the
+   current window, and a messages waiting indicator appears. You have
+   to focus out of the window and then back in the window. this may be
+   fixed already
+
+2. The tray icon is flaky and has been disabled - look in app.py
+   for bSHOW_TRAY
+
+## Fix history
+
+## Fix Audio
+
+The code is in there but it's not working. It looks like audio input
+is working but not output. The code is all in there; I may have broken
+it trying to wire up the ability to set the audio device from the
+command line.
+
+## Fix Video
+
+The code is in there but it's not working.  I may have broken it
+trying to wire up the ability to set the video device from the command
+line.
+
+## NGC Groups
+
+1. peer_id There has been a change of API on a field named
+   ```group.peer_id``` The code is broken in places because I have not
+   seen the path to change from the old API ro the new one.
+
+
+## Plugin system
+
+1. Needs better documentation and checking.
+
+2. There's something broken in the way some of them plug into Qt menus.
+
+3. Should the plugins be in toxygen or a separate repo?
+
+4. There needs to be a uniform way for plugins to wire into callbacks.
+
+## check toxygen_wrapper
+
+1. I've broken out toxygen_wrapper to be standalone,
+   https://git.plastiras.org/emdee/toxygen_wrapper but the tox.py
+   needs each call double checking.
+
+2. https://git.plastiras.org/emdee/toxygen_wrapper needs packaging
+   and making a dependency.
+
+## Migration
+
+Migrate PyQt5 to qtpy - done, but I'm not sure qtpy supports PyQt6.
+https://github.com/spyder-ide/qtpy/
+
+Maybe migrate gevent to asyncio, and migrate to
+[qasync](https://github.com/CabbageDevelopment/qasync)
+(see https://git.plastiras.org/emdee/phantompy ).
+
+(Also look at https://pypi.org/project/asyncio-gevent/ but it's dead).
+
+## Standards
+
+There's a standard for Tox clients that this has not been tested against:
+https://tox.gitbooks.io/tox-client-standard/content/general_requirements/general_requirements.html
+https://github.com/Tox/Tox-Client-Standard
+

+## Toxygen Weechat
+
+You can have a [weechat](https://github.com/weechat/qweechat)
+console so that you can have IRC and jabber in a window as well as Tox.
+There's a copy of qweechat in ```thirdparty/qweechat``` backported to
+PyQt5 and integrated into toxygen. Follow the normal instructions for
+adding a ```relay``` to [weechat](https://github.com/weechat/weechat)
+```
+/relay add ipv4.ssl.weechat 9000
+/relay start ipv4.ssl.weechat
+```
+or
+```
+/set relay.network.ipv6 off
+/set relay.network.password password
+/relay add weechat 9000
+/relay start weechat
+```
+and use the Plugins/Weechat Console to start weechat under Toxygen.
+Then use the File/Connect menu item of the Console to connect to weechat.
+
+Weechat has a Jabber plugin to enable XMPP:
+```
+/python load jabber.el
+/help jabber
+```
+so you can have Tox, IRC and XMPP in the same application!
+
+### Creating servers for IRC over Tor
+
+Create a proxy called tor
+```
+/proxy add tor socks5 127.0.0.1 9050
+```
+
+It should now show up in the list of proxies.
+```
+/proxy list
+```
+
+```
+/nick NickName
+```
+
+## TLS certificates
+
+[Create a Self-signed Certificate](https://www.oftc.net/NickServ/CertFP/)
+
+Choose a NickName you will identify as.
+
+Create a directory for your certificates ~/.config/weechat/ssl/ 
+and make a subdirectory for each server ~/.config/weechat/ssl/irc.oftc.net/ 
+
+Change to the server directory and use openssl to make a keypair and answer the questions:
+```
+openssl req -nodes -newkey rsa:2048 -keyout NickName.key -x509 -days 3650 -out NickName.cer
+chmod 400 NickName.key
+```
+We now combine certificate and key to a single file NickName.pem 
+```
+cat NickName.cer NickName.key > NickName.pem
+chmod 400 NickName.pem
+```
+
+Do this for each server you want to connect to, or just use one for all of them.
+
+### Libera TokTok channel
+
+The main discussion forum for Tox is the #TokTok channel on libera.
+
+https://mox.sh/sysadmin/secure-irc-connection-to-freenode-with-tor-and-weechat/
+We have to create an account without Tor, this is a requirement to use TOR:
+Connect to irc.libera.chat without Tor and register 
+```
+/msg NickServ identify NickName password
+/msg NickServ REGISTER mypassword mycoolemail@example.com
+/msg NickServ SET PRIVATE ON
+```
+You'll get an email with a registration code.
+Confirm registration after getting the mail with the code:
+```
+/msg NickServ VERIFY REGISTER NickName code1235678
+```
+
+Libera has an onion server so we can map an address in tor. Add this
+to your /etc/tor/torrc
+```
+MapAddress palladium.libera.chat libera75jm6of4wxpxt4aynol3xjmbtxgfyjpu34ss4d7r7q2v5zrpyd.onion
+```
+Or without the MapAddress just use
+libera75jm6of4wxpxt4aynol3xjmbtxgfyjpu34ss4d7r7q2v5zrpyd.onion
+as the server address below, but set tls_verify to off.
+
+Define the server in weechat
+https://www.weechat.org/files/doc/stable/weechat_user.en.html#irc_sasl_authentication
+```
+/server remove libera
+/server add libera palladium.libera.chat/6697 -tls -tls_verify
+/set irc.server.libera.ipv6 off
+/set irc.server.libera.proxy tor
+/set irc.server.libera.username NickName
+/set irc.server.libera.password password
+/set irc.server.libera.nicks NickName
+/set irc.server.libera.tls on
+/set irc.server.libera.tls_cert "${weechat_config_dir}/ssl/libera.chat/NickName.pem"
+```
+
+```
+/set irc.server.libera.sasl_mechanism ecdsa-nist256p-challenge
+/set irc.server.libera.sasl_username "NickName"
+/set irc.server.libera.sasl_key "${weechat_config_dir}/ssl/libera.chat/NickName.pem"
+```
+
+Disconnect and connect back to the server. 
+```
+/disconnect libera
+/connect libera
+```
+
+/msg nickserv identify password NickName
+
+
+### oftc.net
+
+To use oftc.net over tor, you need to authenticate by SSL certificates.
+
+
+Define the server in weechat
+```
+/server remove irc.oftc.net
+/server add OFTC irc.oftc.net/6697  -tls -tls_verify
+/set irc.server.OFTC.ipv6 off
+/set irc.server.OFTC.proxy tor
+/set irc.server.OFTC.username NickName
+/set irc.server.OFTC.nicks NickName
+/set irc.server.OFTC.tls on
+/set irc.server.OFTC.tls_cert "${weechat_config_dir}/ssl/irc.oftc.chat/NickName.pem"
+
+# Disconnect and connect back to the server. 
+/disconnect OFTC
+/connect OFTC
+``` 
+You must be identified in order to validate using certs
+```
+/msg nickserv identify password NickName
+```
+To allow NickServ to identify you based on this certificate you need
+to associate the certificate fingerprint with your nick. To do this
+issue the command cert add to Nickserv (try /msg nickserv helpcert).
+```
+/msg nickserv cert add
+```
+
+### Privacy
+
+[Add somes settings bellow to weechat](https://szorfein.github.io/weechat/tor/configure-weechat/).
+Detail from [faq](https://weechat.org/files/doc/weechat_faq.en.html#security).

 Note that we have a lot of branches for different purposes. Master branch is for stable versions (releases) only, so I recommend to open PR's to develop branch. Development of next Toxygen version usually goes there. Other branches used for implementing different tasks such as file transfers improvements or audio calls implementation etc.

 Every module must contain one class derived from PluginSuperClass defined in [plugin_super_class.py](/src/plugins/plugin_super_class.py). Instance of this class will be created by PluginLoader class (defined in [plugin_support.py](/src/plugin_support.py) ). This class can enable/disable plugins and send data to it.

+# Toxygen ToDo List
+
+## Bugs
+
+1. There is an agravating bug  where new messages are not put in the
+   current window, and a messages waiting indicator appears. You have
+   to focus out of the window and then back in the window. this may be
+   fixed already
+
+2. The tray icon is flaky and has been disabled - look in app.py
+   for bSHOW_TRAY
+
+## Fix history
+
+## Fix Audio
+
+The code is in there but it's not working. It looks like audio input
+is working but not output. The code is all in there; I may have broken
+it trying to wire up the ability to set the audio device from the
+command line.
+
+## Fix Video
+
+The code is in there but it's not working.  I may have broken it
+trying to wire up the ability to set the video device from the command
+line.
+
+## NGC Groups
+
+1. peer_id There has been a change of API on a field named
+   ```group.peer_id``` The code is broken in places because I have not
+   seen the path to change from the old API ro the new one.
+
+
+## Plugin system
+
+1. Needs better documentation and checking.
+
+2. There's something broken in the way some of them plug into Qt menus.
+
+3. Should the plugins be in toxygen or a separate repo?
+
+4. There needs to be a uniform way for plugins to wire into callbacks.
+
+## check toxygen_wrapper
+
+1. I've broken out toxygen_wrapper to be standalone,
+   https://git.plastiras.org/emdee/toxygen_wrapper but the tox.py
+   needs each call double checking.
+
+2. https://git.plastiras.org/emdee/toxygen_wrapper needs packaging
+   and making a dependency.
+
+## Migration
+
+Migrate PyQt5 to qtpy - done, but I'm not sure qtpy supports PyQt6.
+https://github.com/spyder-ide/qtpy/
+
+Maybe migrate gevent to asyncio, and migrate to
+[qasync](https://github.com/CabbageDevelopment/qasync)
+(see https://git.plastiras.org/emdee/phantompy ).
+
+(Also look at https://pypi.org/project/asyncio-gevent/ but it's dead).
+
+## Standards
+
+There's a standard for Tox clients that this has not been tested against:
+https://tox.gitbooks.io/tox-client-standard/content/general_requirements/general_requirements.html
+https://github.com/Tox/Tox-Client-Standard
