    Reply to chat messages, a new Movim feature coming soon!

    Timothée Jaussoin · / Movim · Sunday, 1 November, 2020 - 15:02 edit

A new useful #feature has been merged into Movim today. It will also be part of the upcoming 0.19 #release.

This change relies on the standard XEP-0201: Best Practices for Message Threads and allows you to #reply to a chat message using any XMPP account using Movim.

You could already find such feature on other chat platforms like #Telegram or #WhatsApp, the flow is also quite similar: on supported messages, click on the reply button and a little preview will appear next to the chat box input, fill in your message, publish, et voilà !

You can also navigate to the original message by clicking on the little preview (if this message is currently shown in the conversation).

Enjoy :)

    Chat picture resolver and Telegram stickers

    Timothée Jaussoin · / Movim · Friday, 15 May, 2020 - 07:50 edit · 3 minutes

Movim 0.18 is planned to be released soon.

In the meantime, let's have a look at one specific feature that is really useful when you integrate Movim with the Spectrum2 - Telegram bridge.

For those that are not aware, XMPP can connect to other chat networks using tools called "transport". One of the most used is called Spectrum2 and can connect to many other networks thanks to its libpurple support.

Telegram transport setup

What will we do here is:

  • Setup telegram-purple in Spectrum2 on Debian
  • Connect it to a XMPP server (here ejabberd)
  • Adapt the transport to integrate with Movim

Setup Spectrum2 and telegram-purple

Here I will not detail the basic installation, the official Spectrum2 documentation is pretty complete.

Once the repository is setup, please install the base package and the libpurple module:

apt install spectrum2 spectrum2-backend-libpurple

For telegram-purple the README is also quite complete

Create a Telegram transport

Once all the packages are setup, we will create a transport configuration file. You can reuse the spectrum.cfg.example located in the /etc/spectrum2/transports/ as a base.

# nano /etc/spectrum2/transports/spectrum_telegram.cfg

This is basically the config file that I used for my own transport:

server_mode = 0

jid =
password = spectrumpassword
server =
port = 5347
backend_host =




name=Telegram Transport

config = /etc/spectrum2/logging.cfg
backend_config = /etc/spectrum2/backend-logging.cfg

type = sqlite3


When Spectrum2 will connect to the Telegram network, the stickers will be downloaded as files on the server. By default an ugly path is simply sent to the XMPP clients. We will turn it to a proper URL and let Movim to its magic.

To do that we need to configure the Web Storage module. You can also find more documentation about it there.


It's pretty self explanatory. The downloaded stickers will be put in the web_directory directory. The second parameter, web_url, is basically telling Spectrum2 how to general its URL before sending them in the messages.

Configure ejabberd

Then we need to add a new service in our ejabberd.yml configuration file.

    port: 5347
    module: ejabberd_service
    access: all
    ip: ""
    global_routes: false
        password: "spectrumpassword"

Once everything is setup, restart Spectrum2 and ejabberd. For Spectrum2 you can do it using spectrum2_manager or a dedicated systemd configuration file.

Configure our web server

We then need to expose those files to the web. A simple nginx configuration will handle it.

server {

    listen 443 ssl http2;
    listen [::]:443 ssl http2;


    root /home/movim/upload;

    location /spectrum {
        alias /home/movim/movim/spectrum;

Fix the nasty file rights with Incron

If you start to use your Telegram transport at this point you'll notice that the stickers URLs are returning a 403 Forbidden error.

Indeed, Spectrum2 is writting the files in the directory using it's own rights. And this can't be configured.

We will then use another useful tool called Incron. This tool works like CRON but instead of working on time events, it works on file events.

You can find a pretty complete documentation there.

apt install incron 
nano /etc/incron.allow # add your spectrum user there
sudo -su spectrum
incrontab -e

In the incrontab file well then change dynamicaly the rights of the files once they are wrote in the directory (check the documentation for more details).

/home/movim/upload/spectrum   IN_CLOSE_WRITE          chmod 664 $@/$#

Enjoy your nice Telegram stickers in Movim

In Movim, nothing more to do. With the version 0.18, Movim will try to resolve the incoming messages that contains a URL and see if it's a valid picture. Which is the case for Telegram stickers.

You can also note that it works for any other incoming picture URL, including those sent using Conversations or other XMPP clients.

That's all folks!
