![Chat Preview](chat-preview.png)

A terminal Matrix client written in Go using [mautrix](https://github.com/tulir/mautrix-go) and [mauview](https://github.com/tulir/mauview).

Basic usage is possible, but expect bugs and missing features.

## Discussion
Matrix room: [#gomuks:maunium.net](https://matrix.to/#/#gomuks:maunium.net)

## Installation
Once the client becomes actually usable, I'll start making GitHub releases with
precompiled executables. For now, you can either download a CI build from
[GitLab CI](https://mau.dev/tulir/gomuks/pipelines) or compile from source:

0. Install [Go](https://golang.org/) 1.12 or higher
1. Clone the repo: `git clone https://github.com/tulir/gomuks.git && cd gomuks`
2. Build: `go build`

Simply pull changes (`git pull`) and run `go build` again to update.

## Debugging
If something doesn't work but it doesn't crash, check the `/tmp/gomuks/debug.log` file for any errors.

## Developing
Set `DEBUG=1` to enable partial deadlock detection and to write panics to stdout instead of a file.

To build and run with [race detection](https://golang.org/doc/articles/race_detector.html),
use `go install -race` and set `GORACE='history_size=7 log_path=/tmp/gomuks/race.log'`
when starting gomuks, then check `/tmp/gomuks/race.log.<pid>`. Note that race detection
will use a lot of extra resources.

Proper debuggers are too fancy, but normal prints won't work in a TUI application. To write to the
debug log mentioned previously, use the `maunium.net/go/gomuks/debug` package:

```go
package foo

import (
	"maunium.net/go/gomuks/debug"
)

func Foo() {
	debug.Print("WHY ISN'T IT WORKING?!?!?")
	debug.PrintStack()
}
```

## Usage
- switch rooms - `Ctrl + ↑` `Ctrl + ↓` `Alt + ↑` `Alt + ↓`
- ~~scroll chat (line) - `↑` `↓`~~
- scroll chat (page) - `PgUp` `PgDown`
- jump to room - `Alt + Enter`, then `Tab` and `Enter` to navigate and select room
