# Pylos: A Plugin for example file sharing

# This file is part of Pylos. It is an adaptation of the hydrashare platform by the Ladybug dev team (they rock!) for use in the zgf environment.


"""
Use this component to export your GH file to your Pylos repository so that you can upload and share with the community!
-
Provided by Pylos 0.0.03

    Args:
        _fileName: A text name for your example file.
        _fileDescription: A text description of your example file.  This can be a list and each item will be written as a new paragraph.
        changeLog_: A text description of the changes that you have made to the file if this is a new version of an old example file.
        fileTags_: An optional list of test tags to decribe your example file.  This will help others search for your file easily.
        targetFolder_: Input a file path here to the pylos folder on you machine if you are not using the default Github structure that places your pylos github repo in your documents folder.
        includeRhino_: Set to 'True' to include the Rhino file in the zip file that gets uploaded to your pylos fork.  This is important if you are referencing Rhino geometry and have not internalized it in the GH document.  By default, this is set to 'False', which will only include the grasshopper file.
        GHForThumb_: Set to 'True' to have the thumbnail of your example file be of your GH canvas.  By default, the thumbnail will be of the Rhino scene since this is where the cool geometric output of the file displays.  If your file is not producing a geometric output, you will want to set this to 'True.'
        additionalImgs_: A list of file paths to additional images that you want to be shown in Pylos page
        _export: Set to "True" to export the Grasshopper file to Pylos.
    Returns:
        readMe!: ...
