I've been looking for a templating tool for awhile that works well with
single files. My go to templating tool
does not work for
single files, it needs to put files into a directory underneath of it.
By default copier uses double square brackets for its variables. variables in files, directory_names, or file_names will be substituted for their value once you render them.
# hello-py/hello.py.tmpl print('hello-[[name]]')
note! by default copier will not inject variables into your [[template-strings]] unless you use a .tmpl suffix.
Before running copier we need to tell copier what variables to ask for, we do this with a copier.yml file.
# copier.yml name: default: my_name type: str help: What is your name
I prefer to install cli tools that I need globally with pipx, this always gives me access to the tool without worrying about dependency conflicts, bloating my system site-packages, or managing a separate virtual environment for it myself.
pipx install copier
we pass in the directory of the template, and
the directory that we want to render the template into.
copier copy hello-py .
note! the directory '.' is often referred to in cli programs to represent the current working directory that we are calling the command from.
The resulting files will have your variables injected into them if you have setup your template and copier.yml up correctly.
