matrixtool client - Commandline client utilities for a Matrix homeserver


   $ matrixtool client login @username:example.com


This command provides a commandline interface to various client APIs on a
Matrix homeserver. It has various sub-commands that provide particular
functionality, along with some common options between them.

These sub-commands offers a convenience over using simpler tools like F<curl>
directly because they will automatically fill in details like access tokens
and server hostnames, when given a C<user-id> argument. This works by storing
a cache of access tokens in the user's home directory, under

By using the C<matrixtool client login> command you can add an access token
for your user account into this cache:

   $ matrixtool client login @me:example.com
   [OK] Obtained access token

Having logged in, you can now use the C<-u> option to other
C<matrixtool client> subcommands, causing it to automatically supply this
access token on every request:

   $ matrixtool client -u @me:example.com json /_matrix/client/r0/publicRooms

=head1 OPTIONS

The following additional options are recognised

Server to connect to. Usually optional, as it is implied by the C<user-id> if
