NAME
nheko - Desktop client for Matrix using Qt and C++17
SYNOPSIS
nheko [OPTIONS]
DESCRIPTION
The motivation behind the project is to provide a native desktop app for Matrix that feels
more like a mainstream chat app (Element, Telegram etc) and less like an IRC client.
OPTIONS
-h, --help
Displays help on commandline options.
--help-all
Displays help including Qt specific options.
-v, --version
Displays version information.
--debug
Alias for --log-level trace.
-l, --log-level <level>
Set the global log level, or a comma-separated list of <component>=<level> pairs, or
both. For example, to set the default log level to warn but disable logging for the ui
component, pass warn,ui=off.
levels: trace debug info warning error critical off
components: crypto db mtx net qml ui
Log levels can also be set in the NHEKO_LOG_LEVEL environment variable, using the same
syntax. It will be overridden by this command line option.
-L, --log-type <type>
Set the log output type. A comma-separated list is allowed. The default is
file,stderr.
types: file stderr none
The log type can also be set in the NHEKO_LOG_TYPE environment variable, which will be
overridden by this command line option.
-p <profile>, --profile <profile>
Creates a unique profile, which allows you to log into several accounts at the same
time and start multiple instances of nheko. Use default to start with the default
profile.
-C, --compact
Allows shrinking the database, since LMDB databases don’t automatically shrink when
data is deleted. Possibly allows some recovery on database corruption.
FAQ
How do I add stickers and custom emojis?
Stickers and custom emojis are organized in image packs. There is one user image pack that
only your account has access to and there are room image packs that are accessible by
everyone in the room they are defined in. You can activate a room image pack globally to
use it in any room.
To manage image packs in nheko, go to the room settings and enter the Sticker & Emote
Settings. You will see the Private pack (your user image pack) and can edit it there. The
Shortcode is a unique identifier you use to select the image with and the Body is the
alternate text that is displayed on clients that don’t support images (like the alt tag in
HTML images).
If you have the necessary permissions you can create new room packs with the button at the
bottom of the image pack list. They are the same as the user pack but you can create as
many as you want and everyone in the room can use them. It might be a good idea to create
an extra room just for your image packs to make sharing easier.
