SYNOPSIS

go-sendxmpp [-cdilnt] [-a value] [-f value] [--headline] [--help] [-h value] [-j value] [-m value] [--muc-password value] [--oob-file value] [--ox] [--ox-delete-nodes] [--ox-genprivkey-rsa] [--ox-genprivkey-x25519] [--ox-import-privkey value] [--ox-passphrase value] [-p value] [--raw] [--timeout value] [--tls-version value] [-u value] [--version] [recipients…]

DESCRIPTION

A tool to send messages to an XMPP contact or MUC inspired by (but not as powerful as) sendxmpp.
You can either pipe a programs output to go-sendxmpp, write in your terminal (put ^D in a new line to finish) or send the input from a file (-m or --message). The account data is expected at ~/.config/go-sendxmpp/config (preferred), ~/.config/go-sendxmpp/sendxmpprc (deprecated) ~/.sendxmpprc (for compatibility with the original perl sendxmpp) if no other configuration file location is specified with -f or --file.

OPTIONS

-a, --alias=[value]
Set alias/nickname for chatrooms.
-c, --chatroom=[value]
Send message to a chatroom.
-d, --debug
Show debugging info.
-f, --file=[value]
Set configuration file. (Default: ~/.config/go-sendxmpp/config)
--headline
Send message as type headline.
--help
Show help.
-h, --http-upload=[value]
Send a file via http-upload.
-i, --interactive
Interactive mode (for use with e.g. tail -f).
-j, --jserver=[value]
XMPP server address.
-l, --listen
Listen for messages and print them to stdout. If JIDs are specified only messages from those contacts are shown. If no JIDs are specified all received messages will be shown.
-m, --message=[value]
Set file including the message.
--muc-password=[value]
Password for password protected MUCs.
-n, --no-tls-verify
Skip verification of TLS certificates (not recommended).
--oob-file=[value]
URL to send a file as out of band data.
--ox
Use "OpenPGP for XMPP" encryption (experimental).
Ox in go-sendxmpp only supports sending encrypted 1-1 messages. Sending to groupchats and sending encrypted files is not supported. There is no check whether the recipients key is trusted as there is no local keyring used. Go-sendxmpp just uses the most recent key that is provided via pubsub and checks that it is not expired. As a user facing client a notification would be shown that a new key is available and ask the user whether to use the new key or stick to the old one. As go-sendxmpp is usually used in scripts it just accepts the new key to prevent the user from missing a new notification due to changed keys.
--ox-delete-nodes
Delete existing OpenPGP nodes on the server.
--ox-genprivkey-rsa
Generate a private OpenPGP key (RSA 4096 bit) for the configured account (via config file or -u and -p) and publish the corresponding public key. Go-sendxmpp will save the key in $XDG_DATA_HOME/go-sendxmpp/oxprivkeys or $HOME/.local/share/go-sendxmpp/oxprivkeys. To protect the key a passphrase might be set using --ox-passphrase while generating the key.
If there is an existing private key for "OpenPGP for XMPP" created by another client (e.g. profanity) it might be imported using --ox-import-privkey.
--ox-genprivkey-x25519
Generate a private OpenPGP key (X25519) for the configured account (via config file or -u and -p) and publish the corresponding public key. Go-sendxmpp will save the key in $XDG_DATA_HOME/go-sendxmpp/oxprivkeys or $HOME/.local/share/go-sendxmpp/oxprivkeys. To protect the key a passphrase might be set using --ox-passphrase while generating the key.
If there is an existing private key for "OpenPGP for XMPP" created by another client (e.g. profanity) it might be imported using --ox-import-privkey.
--ox-import-privkey=[value]
Import an existing private OpenPGP key.
--ox-passphrase=[value]
Passphrase for locking and unlocking the private OpenPGP key.
--tls-version=[value]
Minimal TLS version. 10 (TLSv1.0), 11 (TLSv1.1), 12 (TLSv1.2), 13 (TLSv1.3) (Default: 12)
-p, --password=[value]
Password for XMPP account.
--raw
Send raw XML. To send raw XML to a contact as normal chat message no contact must be specified. To send raw XML to a MUC you have to specify the MUC via -c and go-sendxmpp will join the MUC.
--timeout=[value]
Connection timeout in seconds. (Default: 10)
-t, --tls
Use direct TLS.
-u, --username=[value]
Username for XMPP account (JID).
--version
Show version information.

SCRAM

Go-sendxmpp supports Salted Challenge Response Authentication Mechanism (SCRAM). If go-sendxmpp successfully connects using SCRAM it will create a file ~/.local/share/go-sendxmpp/[your_jid]/authmechanism containing the name of the used mechanism. It will read this file and use the same mechanism for future connections and fail if it is not available. This is to protect against downgrades by a Machine In The Middle (MITM). If you want to upgrade to another mechanism (e.g. if SCRAM-SHA-1-PLUS gets available for your server that previously only supported SCRAM-SHA-1) you have to manually edit the file. It is not recommended to delete the file and let go-sendxmpp recreate it as this would make it vulnerable to downgrade attacks for the next connection attempt.

SHELL COMPLETIONS

ZSH

There are no shell completions yet (contributions welcome) but for zsh it is possible to automatically create completions from --help which might work good enough.

Just place the following in your ~/.zshrc or ~/.zshrc.local:

compdef _gnu_generic go-sendxmpp
