Usage

Build HorusLib

$ git clone https://github.com/projecthorus/horusdemodlib.git
$ cd horusdemodlib && mkdir build && cd build
$ cmake ..
$ make
$ make install

TODO: Make a separate horusdemodlib python package, which handles building of the library.

Create a Virtual Environment

Create a virtual environment and install dependencies.

$ git clone https://github.com/projecthorus/horus-gui.git
$ cd horus-gui
$ python3 -m venv venv
$ source venv/bin/activate
(venv) $ pip install pip -U       (Optional - this updates pip)
(venv) $ pip install -r requirements.txt

Install Package

Install package in a editable state. This type of installation allows a developer to make changes to the source code while retaining the installation entry points so it can be used like a normal install.

(venv) $ pip install -e .

Run

$ python -m horusgui.gui
