# go-sendxmpp

## about

A tool to send messages to an XMPP contact or MUC inspired by [sendxmpp](https://sendxmpp.hostname.sk/).
You can find other sendxmpp alternatives in the [XSF wiki](https://wiki.xmpp.org/web/User:MDosch/Sendxmpp_incarnations).

## support

You might join the [chat](https://join.jabber.network/#go-sendxmpp@chat.mdosch.de?join) if you have problems, 
want to contribute or just want to talk about the project. You might also talk about any of the other 
sendxmpp incarnations. :)

## installation

### repositories including go-sendxmpp

[![Packaging status](https://repology.org/badge/vertical-allrepos/go:sendxmpp.svg)](https://repology.org/project/go:sendxmpp/versions)

### manual installation

Latest release:

```plain
$ go install salsa.debian.org/mdosch/go-sendxmpp@latest
```

Current development version:

```plain
$ go install salsa.debian.org/mdosch/go-sendxmpp@master
```

You will find the binary in `$GOPATH/bin` or, if set, `$GOBIN`.

### binaries

There are some (automatically built and untested) binaries linked to the
[release](https://salsa.debian.org/mdosch/go-sendxmpp/-/releases).

## usage

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` if no other configuration file location 
is specified with `-f` or `--file`. The configuration file is expected to be in the following format:

```plain
username: <your_jid>
password: <your_jabber_password>
```

If this is not sufficient to connect you might also specify `jserver` and `port`. It is also possible to
use a password manager. In this case the `password` setting should be replaced by the `eval_password`
setting:    

```
eval_password: <command_to_unlock_your_password>
```

You can also configure the alias/nickname for MUCs via the `alias` setting:

```
alias: <my_alias>
```

If no configuration file is present or if the values should be overridden it is possible to define 
the account details via command line options:

### examples

Send a message to two recipients using a configuration file.

```bash
cat message.txt | ./go-sendxmpp -f ./sendxmpp recipient1@example.com recipient2@example.com
```

Send a message to two recipients directly defining account credentials.

```bash
cat message.txt | ./go-sendxmpp -u bob@example.com -j example.com -p swordfish recipient1@example.com recipient2@example.com
```

Send a message to two groupchats (`-c`) using a configuration file.

```bash
cat message.txt | ./go-sendxmpp -cf ./sendxmpp chat1@conference.example.com chat2@conference.example.com
```

Send file changes to two groupchats (`-c`) using a configuration file.

```bash
tail -f example.log | ./go-sendxmpp -cif ./sendxmpp chat1@conference.example.com chat2@conference.example.com
```

### shell completion

#### 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`:

``` bash
compdef _gnu_generic go-sendxmpp
```
