# Gempyre-Python 

The easy and productive UI library for Python. 

## Gempyre

Gempyre is a C++ GUI library, see https://github.com/mmertama/Gempyre.git.

## install from PyPi

pip install Gempyre  

## Build from sources

Create a venv (https://docs.python.org/3/library/venv.html)

  ```bash
    pip install .
  ```

### Notes:
#### Raspberry OS

Todo: Needs optional RASPEBERRY flag to be passed to CMake. 
  
### Missing libraries  

You may need python3-dev and python3-pip be installed. This may depend on your evironment,
In linux e.g. apt-get install python3-dev, in MacOS look brew.

#### Windows:

```
# Windows has a limit of path lengths to 260 chars - 8-+ 
#   
#   "260 characters is enough for everybody"
#                 - W.G III

```

That may cause troubles (especially with python -m build).


### Run

After install, you just run the script!

  ```bash
  $ python3 test/telex_test.py
  ```

## API

See examples how to use e.g. [telex_test](https://github.com/mmertama/Gempyre-Python/blob/master/test/telex_test.py)

The programming interface is very same as in [Gempyre](https://github.com/mmertama/Gempyre.git)
- except I changed function and method name naming from CamelCase to more pythonic snake_case (Im not sure if that was a right choice).

Please look  [Gempyre](https://github.com/mmertama/Gempyre.git) for documentation.

Please note that Gempyre Core and Gempyre Graphics are part of Python API, but not Gempyre-Utils, it has C++ utilites and thus not applicable for Python programmers as everything and more is already there!
  
## Examples

See [examples and demos](https://github.com/mmertama/Gempyre-Python/tree/master/examples)

See [small test apps](https://github.com/mmertama/Gempyre-Python/tree/master/test)

### Minimum single file app

```py

#!/usr/bin/python3
import Gempyre
import os
import sys
from Gempyre import resource

html = '''
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
  <meta http-equiv="Pragma" content="no-cache" />
  <meta http-equiv="Expires" content="0" />
</head>
<body>
  <script src="/gempyre.js"></script>
  Hello!
</body>
</html>  
'''


if __name__ == "__main__":
    map, names = resource.from_bytes({"ui.html": bytes(html, 'utf-8')})
    ui = Gempyre.Ui(map, names["ui.html"])
    ui.run()
    

```


### Minimum application with an external UI file

  ```py
  import Gempyre
  import os
  import sys
  from Gempyre import resource

  name = os.path.join(os.path.dirname(sys.argv[0]), "hello.html")
  map, names = resource.from_file(name)
  ui = Gempyre.Ui(map, names[name])
  ui.run()
  ```

#### HTML

Assumed to be found in the same folder as the script

  ```html
  <!DOCTYPE html>
  <html>
    <head>
      <meta charset="utf-8">
    </head>
    <body>
      <script src="/gempyre.js"></script>
      Hello!
    </body>
  </html>
  ```

### Application with interaction
#### Python
```py

def main():
    name = os.path.join(os.path.dirname(sys.argv[0]), "example2.html")
    map, names = resource.from_file(name)
    ui = Gempyre.Ui(map, names[name])
    output = Gempyre.Element(ui, "output")
    open_button = Gempyre.Element(ui, "open")
    open_button.subscribe("click", lambda _: output.set_html("Hello"))
    ui.run()

if __name__ == "__main__":
    main()
```
#### HTML
  ```html
  <!DOCTYPE html>
  <html>
    <head>
      <meta charset="utf-8">
      <title>test</title>
    </head>
    <body>
      <script src="/gempyre.js"></script>
      <button id="open">Open</button>
      <pre id="output"></pre>
    </body>
  </html>
  ```
