Configuration

Both matteridge-specific options and slidge generic options can be set using config text file(s), command-line arguments, or environment variables.

Config files

Location

By default, matteridge uses all config files found in /etc/slidge/conf.d/*.conf. You can change this using the SLIDGE_CONF_DIR env var, eg SLIDGE_CONF_DIR=/path/dir1:/path/dir2:/path/dir3.

We recommend using /etc/slidge/conf.d/common.conf file to set the options common to several slidge-based gateways (eg, attachment handling, logging options, etc.), then use a matteridge-specific dedicated config file, eg /etc/slidge/matteridge.conf.

Point to this specific file using the -c command line argument when launching matteridge.

matteridge -c /etc/slidge/matteridge.conf

Syntax

Config files are simple text files with key=value entries.

some-option=some-value
some-other-option=some-other-value

Command-line arguments

To pass options as command-line arguments, prepend their name with --.

matteridge --some-option=some-value --some-other-option=some-other-value

Environment variables

To pass options as environment variables:

SLIDGE_SOME_GENERIC_OPTION=some-value
MATTERIDGE_SOME_SPECIFIC_OPTION=some-other-value

matteridge-specific config

matteridge provides the instance-wide options displayed in the table below.

name default

help

backfill-posts 30

Number of posts to fetch for channels (before slidge was launched)

max-participants 100

Maximum number of participants to fetch in groups.

user-agent Mattermost/XMPP (Matteridge)

User-Agent string (set as header on requests sent to Mattermost servers)

Generic slidge config

Note

The following options are for slidge version 0.3.11. Depending on how you installed matteridge, you might have a different version of slidge. Use matteridge --help for the exact list of options you can use.

Slidge provides the generic instance-wide options displayed in the table below. They may not all have an effect on matteridge’s behaviour.

Mandatory settings

name default

help

secret unset

The gateway component’s secret (required to connect to the XMPP server)

jid unset

The gateway component’s JID

Basic configuration

name default

help

admins ()

JIDs of the gateway admins

mam-max-days 7

Maximum number of days for group archive retention.

port 5347

The XMPP server’s port for incoming component connections

server localhost

The XMPP server’s host name. Defaults to localhost, which is the standard way of running slidge, on the same host as the XMPP server. The ‘Jabber Component Protocol’ (XEP-0114) does not mention encryption, so you *should* provide encryption another way, eg via port forwarding, if you change this.

legacy-module unset

Importable python module containing (at least) a BaseGateway and a LegacySession subclass. NB: this is not needed if you use a gateway-specific entrypoint, e.g., `slidgram` or `python -m slidgram`.

home-dir inferred

Directory where slidge will writes it persistent data and cache. Defaults to /var/lib/slidge/${SLIDGE_JID}.

user-jid-validator inferred

Regular expression to restrict users that can register to the gateway, by JID. Defaults to .*@${INFERRED_SERVER}. INFERRED_SERVER is derived for the gateway JID, by removing whatever is before the first encountered dot in it. Example: if slidge’s JID=slidge.example.org, INFERRED_SERVER=example.org.

Attachments

name default

help

attachment-maximum-file-name-length 200

Some legacy network provide ridiculously long filenames, strip above this limit, preserving suffix.

convert-stickers False

Convert lottie vector stickers (from the legacy side) to webp animations.

fix-filename-suffix-mime-type False

Fix the Filename suffix based on the Mime Type of the file. Some clients (eg Conversations) may not inline files that have a wrong suffix for the MIME Type. Therefore the MIME Type of the file is checked, if the suffix is not valid for that MIME Type, a valid one will be picked.

no-upload-file-read-others False

After writing a file in NO_UPLOAD_PATH, change its permission so that ‘others’ can read it.

no-upload-method copy

Whether to ‘copy’, ‘move’, ‘hardlink’ or ‘symlink’ the files in no-upload-path.

no-upload-path None

Instead of using the XMPP server’s HTTP upload component, copy files to this dir. You need to set NO_UPLOAD_URL_PREFIX too if you use this option, and configure an web server to serve files in this dir.

no-upload-url-prefix None

Base URL that servers files in the dir set in the no-upload-path option, eg https://example.com:666/slidge-attachments/

upload-requester None

Set which JID should request the upload slots. Defaults to the user’s JID if IQ/get privileges granted for the ‘urn:xmpp:http:upload:0’ namespace; the component JID otherwise.

upload-service None

JID of an HTTP upload service the gateway can use. This is optional, as it should be automatically determined via servicediscovery.

upload-url-prefix None

This is an optional setting to make sure the URL of your upload service is never leaked to the legacy network in bodies of messages. This can happen under rare circumstances and/or bugs,when replying to an attachment. Set this to the common prefix of the public URL your attachments get, eg https://upload.example.org:5281/

use-attachment-original-urls False

For legacy plugins in which attachments are publicly downloadable URLs, let XMPP clients directly download them from this URL. Note that this will probably leak your client IP to the legacy network.

Logging

name default

help

log-file None

Log to a file instead of stdout/err

log-format %(levelname)s:%(name)s:%(message)s

Optionally, a format string for logging messages. Refer to https://docs.python.org/3/library/logging.html#logrecord-attributes for available options.

Advanced settings

name default

help

avatar-resampling-threads 2

Number of additional threads to use for avatar resampling. Even in a single-core context, this makes avatar resampling non-blocking.

avatar-size 200

Maximum image size (width and height), image ratio will be preserved

component-name None

Overrides the default component name with a custom one. This is seen in service discovery and as the nickname of the component in chat windows.

dev-mode False

Enables an interactive python shell via chat commands, for admins.Not safe to use in prod, but great during dev.

ignore-delay-threshold 300

Threshold, in seconds, below which the <delay> information is stripped out of emitted stanzas.

partial-registration-timeout 3600

Timeout before registration and login. Only useful for legacy networks where a single step registration process is not enough.

qr-timeout 60

Timeout for QR code flashing confirmation.

strip-leading-emoji-adhoc False

Strip the leading emoji in ad-hoc command names, if present, in case you are a emoji-hater.

welcome-message None

Overrides the default welcome message received by newly registered users.

db-url inferred

Database URL, see <https://docs.sqlalchemy.org/en/20/core/engines.html#database-urls>. Defaults to sqlite:///${HOME_DIR}/slidge.sqlite

Advanced logging configuration

To customize the output of the slidge, you can use the command line argument --log-config to specify a logging configuration file.
