Fedora 36 : first steps with the Hy.

Hy is a dialect of the Lisp programming language designed to interact with Python by translating s-expressions into Python's abstract syntax tree (AST). Hy was introduced at Python Conference (PyCon) 2013 by Paul Tagliamonte.

This is quite similar to the old GIMP Script Fu that I've worked with in the past. The syntax assumes a join like tabs in HTML, only we'll use parentheses. I haven't studied in detail the implications it has with the python language, but it certainly wasn't invented for nothing.

First, you need to install it with the pip tool.

[mythcat@fedora ~]$ pip3 install hy --user
Collecting hy
...
Successfully built hy
Installing collected packages: funcparserlib, colorama, hy
Successfully installed colorama-0.4.5 funcparserlib-1.0.0 hy-0.24.0

The I test some examples:

[mythcat@fedora ~]$ hy
Hy 0.24.0 using CPython(main) 3.10.5 on Linux
=> (setv a 1)
=> "hello world"
"hello world"
=> (setv mylist [1 2 3])

=> (get mylist 0)
1
=> (defn greet [name]
...  "Hello "
...  (print "Hello " name))
=> (greet "mythcat")
Hello  mythcat

You can test it online with this online tool:

Fedora 35 : PyQt6 and Python 3.

I tested the new python version 10 and pyqt version 6 on the fedora version 35 distribution.

[mythcat@fedora ~]$ python

I install PyQt6 easy with pip tool:

[mythcat@fedora ~]$ pip install PyQt6 --user

I tested with this python source code and it works fine.

import sys
from PyQt6.QtWidgets import QApplication, QWidget

def main():

    app = QApplication(sys.argv)

    w = QWidget()
    w.resize(250, 200)
    w.move(300, 300)

    w.setWindowTitle('Simple')
    w.show()

    sys.exit(app.exec())

if __name__ == '__main__':
    main()
