## Introduction

**Crasis – semigraphical interface to [ZI](https://github.com/z-shell/zi)**

Zsh exposes its parser via `(z)` substitution flag.

Parsing `.zshrc` is totally possible.

This way `Crasis` lets you edit your `ZI` commands located in `.zshrc`.

All in pure `Zshell` code.

No more commenting-out a line with a text editor to disable plugin, cluttering `.zshrc`, now you can just **press a button**.

`Crasis` uses pure-Zshell [ZUI](http://github.com/z-shell/zui/) library to create `ncurses` interface.

## Installation & Basic Use

Install [ZI](https://github.com/z-shell/zi) and add following commands to `.zshrc`:

```SystemVerilog
zi light z-shell/zui
zi light z-shell/zi-crasis
```

To use, invoke `crasis [optional zshrc path]` or press `Ctrl-o-k`.

Global variables `CRASIS_THEME` and `CRASIS_LAYOUT` can be used to override configuration file `crasis.conf` (located in plugin's
tree), i.e.:

```SystemVerilog
CRASIS_THEME="zdharma-256" CRASIS_LAYOUT="contract" crasis
```

`256`-color themes require Zsh `5.3` or later.
