"""
Create a new development project.
Bare usage will simply create an empty folder in your configured projects
directory.
You can also create a project from a cookiecutter or copier template by passing a valid
url to the '--cookie/-c' or '--copier/-C' flags.
If you just want a very simple, language-specific starting template, use the
'--starter/-s' option.
By default, pytoil will initialise a local git repo in the folder and commit it,
following the style of modern language build tools such as rust's cargo. You can disable
this behaviour by setting 'git' to false in pytoil's config file
or by passing the '--no-git/-n' flag here.
If you want pytoil to create a new virtual environment for your project, you
can use the '--venv/-v' flag. Standard python and conda virtual environments
are supported.
If the '--venv/-v' flag is used, you may also pass a list of python packages
to install into the created virtual environment. These will be delegated to
the appropriate tool (pip or conda) depending on what environment was created.
If the environment is conda, the packages will be passed at environment creation
time meaning they will have their dependencies resolved together. Normal python
environments will first be created and then have specified packages installed.
If 'common_packages' is specified in pytoil's config file, these will automatically
be included in the environment.
To specify versions of packages via the command line, you must enclose them
in double quotes e.g. "flask>=1.0.0" not flask>=1.0.0 otherwise this will
be interpreted by the shell as a command redirection.
Examples:
$ pytoil new my_project
$ pytoil new my_project --cookie https://github.com/some/cookie.git
$ pytoil new my_project --venv conda
$ pytoil new my_project -c https://github.com/some/cookie.git -v conda --no-git
$ pytoil new my_project -v venv requests "flask>=1.0.0"
$ pytoil new my_project --starter python
