**eqnx** (equinox) is a library for composing applications by merging
independent plugins. It is single-threaded, event-based and easy to use.

> [!NOTE]

Plugins are autonomous components that draw on a character matrix and can
orchestrate other subcomponents, so the developer controls the layout and how
interaction is distributed between them.

## Building a program

eqnx can generate a script that runs an eqnx program (see `eqnx -h`):

```
$ ./eqnx -p esx/calendar.esx -s plugins/ --build
```

## Calendar

```
$ eqnx -p esx/calendar.esx
```

A plugin to see and edit tasks stored in a TOML file: the newest version of
[todo](todo.md).

| Key | Action |
|---|---|
| `hjkl` | Move |
| `C-n`, `C-p` | Next / previous month |
| `esc` | Close the current view |
| `c` | Create a task in a day |

Buttons can also be clicked with the mouse.

## zrun

A Rust rewrite of [zrun](zrun.md) as an eqnx program:

```
$ ./zrun_eqnx/zrun.sh
```
