Hecto^(graph)

A small library for rendering blueprints of projects.

• Works with local paths and git URLs.
• Your project can include any file and Hecto can dynamically replace values in any kind of text files.
• It generates a beautiful output and take care of not overwrite existing files, unless instructed to do so.

How to use

pip install hecto

from hecto import render_blueprint

# Create a project from a local path
render_blueprint('path/to/project/template', 'path/to/destination', context={"foo": "bar"})

# Or from a git URL.
# You can also use "gh:" as a shortcut of "https://github.com/"
# Or "gl:"  as a shortcut of "https://gitlab.com/"
render_blueprint('https://github.com/jpsca/base36.git', 'path/to/destination')
render_blueprint('gh:jpsca/base36.git', 'path/to/destination')
render_blueprint('gl:jpsca/base36.git', 'path/to/destination')

How does it works

For each file, if the file has a .tt, .append, or .prepend extension, even if the extension is not the last one, like *.tt.py, it will be treated as a template file and rendered with the provided context.

• .tt files will be rendered and saved to its destinations.
• .append files will be rendered and appended to its destinations.
• .prepend files will be rendered and prepended to its destinations.
• Other files will be copied as-is.

To be able to work with regular Jinja files, the files are rendered using [[ and ]] instead of {{ and }}; and [% and %] instead of {% and %}. You can also use these delimiters in your file names.

If the files already exists and force is False, you will be asked for confirmation before overwriting them.
