# Haki
[](https://github.com/grkek/haki)
### GUI framework with GTK4 component generation using HTML, CSS and JavaScript
- None of the components generated by Layout contain anything remotely related to a Web-Browser.
- Compiled binary reads the custom HTML and builds the GTK components. Since it is already a pre-built release version, it is pretty fast at generating the UI components.
- The compiler supports CSS and JavaScript compilation, which glues the components and makes the UI interactive.
- The JavaScript engine is Duktape, it supports Babel 6.26.0 and CoreJS 2.6.11.
- The CSS is limited to GTK4 specification.
## Installation
Before you clone the shard and build it, install the GTK libraries.
Add this to your application's `shard.yml`:
```yaml
dependencies:
haki:
github: grkek/haki
```
And run this command in your terminal:
```bash
shards install
./bin/gi-crystal
```
# Code example
Add this to your `application.cr`:
```crystal
require "haki"
# Disable GC for now.
GC.disable
html = <<-HTML
Hello, World!
HTML
builder = Haki::Builder.new
# Make sure you point the path the correct way.
builder.build_from_string(html)
```
Compile the `application.cr` file.
```bash
crystal run application.cr -Dpreview_mt --error-trace
```
And you should have a GUI window with a "Hello, World!" text.
