OM-py

Cite this repository:

OM-py bring python to visual enviroment. For this library work properly you need to download it, and then read the topics in this documentation:

• Install OM-Sharp;
• Install OM Libraries;
• Install Python (see your plataform).

Download

OM-py is a bridge between Python and OM environments. What it does is format some types of data that are differently represented. For example, one list of numbers in OM is represented by (1 2 3 4 5). In Python, the same list is represented by [1, 2, 3, 4, 5]. Sounds inside OM are represented by a class, for example, #<sound 23186913>. To send this #<sound 23186913> to Python, we need to save it in a temp folder and then give it to Python by a pathname.

Besides that, it will run the python code, and bring the formatted result to OM. For that, we have two main OM-boxes: py and py-code. The py is like and object and will send to OM-Sharp all python vars insinde to_om(). The example below, will return 4 to OM.

```lisp (pyvar () " from ompy.pythontoom import toom sum = 2 + 2 toom(sum) # If you want to use something inside OM, you need to print it.

" ) ``` Use variables inside OM is simple:

```lisp (pyvar (myomnumber) " from ompy.pythontoom import toom sum = 2 + myomnumber toom(sum) # If you want to use something inside OM, you need to print it.

" ) `` Withmyomnumberinside py_var it will open and input in thepy` box.

OM-py work with vscode too. For that select py or py-code box and press z. If the key is added to some function in OM-Sharp, I will need to change it.

Use your own enviroment

If you want, you can define your own Python enviroment in external:

by using: conda activate composition for example in the Python enviroment!

1. Scripts/activate.bat for Windows;
2. bin/activate for Ubuntu.

A beautiful example for spatialization:

With this library will be able to: * Use python scripts using OM variables. * Use VST3, vamp-plugins, tools for analisys and others; * Easy Visual Python Multithreading with OM-CKN; * All that Python could do.

Install OM-Sharp

Go to https://github.com/cac-t-u-s/om-sharp/releases/ and download it from your plataform!

Install OM Libraries

To install OM External Libraries see the process in: https://cac-t-u-s.github.io/pages/libraries!

Install Python

Windows

To install Python on Windows you need first download Python 3.9 in the Python website.

https://www.python.org/downloads/release/python-399/

At the bottom of the page, you will see the Windows installer (64-bit).

• Download it!

• Then double click in the "python-3.9.9-amd64.exe".
• Make sure to mark the option Add Python 3.9 to PATH.
• Click on Install Now.

• Click in Close.
• Finally load om-py from OM-Sharp, the first load will download some things. The could take some time

To make sure that all things are working: * Open OM-Sharp * Load om-py; * Then go to Help-> Help Patches... -> om-py * Then open the path use-py-inside-om. * Then evaluate the patch!

If you heard a sound probably, it is working!! If not, please let me know!

Linux

In Linux the process is a little more simple! * Open the terminal; * If you have no python in your machine (improbable) type sudo apt install python3 * Then install pip typing, sudo apt-get -y install python3-pip * Install Virtual Env: sudo apt install python3-venv * Finnaly, load the om-py library, the first load will download some things. The could take some time. To make sure that all things are working: * Open OM-Sharp * Load om-py; * Then go to Help-> Help Patches... -> om-py * Then open the path use-py-inside-om. * Then evaluate the patch!

MacOS

• Install Python from https://www.python.org/downloads/release/python-399/! Maybe it is already installed!
• On Mac Terminal, run python3 -m pip install virtualenv.
• Go to Help -> Help Patches -> OM-py -> for-mac!! Open the patch and then run the TextBuffer and execute (on Mac terminal) these two lines of code.
• Load om-py Library in OM-Sharp, the first load will download some things. The could take some time.
• To open python scripts in vscode you need:
  • Download, Install and Open vscode.
  • Open command palette. (shift + command + p)
  • Look for Install code command in PATH.
  • Press ENTER.
  • If this does not work read this https://code.visualstudio.com/docs/setup/mac.
