patrix is a simple command line client for Matrix written in perl. It can create rooms, send text messages or files to rooms. I use it to send Zabbix alerts to a Matrix room, a bit like sendxmpp can do with XMPP.

It requires the following perl modules

• LWP::UserAgent
• HTTP::Request
• Config::Simple
• File::HomeDir
• File::Basename
• File::MimeInfo
• Path::Tiny
• Getopt::Long
• URI::Escape
• JSON
• Term::ReadKey

For now it's very limited, and can only send text messages and files to a room. Here're the vailable options:

• --user: specify the user you want to login as
• --password: the password to auth against the HS
• --server: the HS you want to connect to. Default is https://matrix.org
• --access_token: can be used instead of --user and --password
• --room: the room to which the message must be sent. Can be a room ID or a room alias
• --message: the text message you want to send. If you send something on stdin, it's assumed to be the text to send and this option is ignored
• --debug: if present, will be verbose
• --conf: path to a conf file. Default conf file is ~/.patrixrc
• --file: if action is send-file, specify the path of the file to send
• --invite: a matrix ID (@user:server.domain.tld) to invite in a room. Can be specified several times. Valid for create-room and modify-room
• --name: set the name of a room. Valid for create-room and modify-room
• --topic: set the topic of a room. Valid for create-room and modify-room
• --alias: set an alias for a room. Valid for create-room and modify-room
• --join_rules: change joining rules. Can be either public (anyone can join the room) or invite (you must be invited to join the room)
• --federation: Enable the federation when creating a room. Default is enabled. Can be turned of with --no-federation
• --action: what to do. Valid actions are
  • send-msg (default): send the text message
  • send-message: an alias for send-msg
  • send-notice: send a notice. Very similar to send-msg but the client may display it differently. Eg Riot will not notify you for notices
  • send-file: send a binary file. --file must be set
  • create-room: create a new room
  • modify-room: change an existing room (add an alias, set name, topic, join_rules, invite)
  • get-access-token: just login and print the access token
  • get-room-list: prints the list of public rooms of this server
  • get-room-id: resolve a room alias to its ID

All the available options can be set a the configuration file using a simple ini style format, eg

user=alert
password=p@ssw0rd
room=!BWdARvAgNQGgSjgtAG:matrix.domain.com

Options given on the command line take precedence over the config file

Examples:

cat /var/log/boot.log | patrix --room='#bootlogs:matrix.domain.com' --action=send-notice

patrix --action=send-file --file=/home/dani/archive.tgz --user=dani --password=secret --server=matrix.domain.com

patrix --debug --message="Hello World"

patrix --action=create-room --name="Human readable room name" --invite="@dani:matrix.example.com"

patrix --action=modify-room --join_rules=public --topic='New topic' --room='!uXfknaWNcAnvthnIms:matrix.example.com' --invite='@admin:matrix.example.com'
