Migrating Old Projects¶

The copier tool allows us to easily transform an old repository, that has not been created with the template, to one that is linked to a copier template.

This can be simply done by just copying the template onto an existing repository.

$ copier copy --trust "git+https://gitlab.tuwien.ac.at/cookbooks/templates/tu-cookbook-python" path/to/old/repo/

If a file from the template is not yet present in the repo copier will render and add it.

If a file already exists copier asks the user, wheter or not the file should be overwritten.

It is recommended to always overwrite the files, as they might
include content that is necessary to the repo.

With `Git` the user can anyway remove unwanted content easily after
closer inspection.
