Changelog

All notable changes to this project will be documented in this file. This project adheres to PEP 440 versioning schema, and the changelog itself conforms to Keep A Changelog.

[Unreleased]

All changes here. Summary:

Added

  • Allow using additional Jinja 2 extensions.
  • Major version mismatch warning. If your Copier version is too new, you'll be warned.
  • Specific exceptions, which will help on error detection for API usages.
  • Multiline questions.
  • Conditional questions.
  • Placeholders.
  • Interactive TUI for questionaries. Prompts are way cooler now. 😎
  • Python 3.9 support.
  • Support empty templates suffix, telling Copier to render every file.
  • Added --defaults flag to use default answers to questions, which might be null if not specified.
  • Added --overwrite flag to overwrite files that already exist, without asking.

Changed

  • Fully refactored core.
  • Running copier copy on a preexisting project now recopies the project instead of updating it. That means that it respects old answers, but ignores history diff.
  • We use Jinja 2 defaults now. {{ }} instead of [[ ]] and similar.
  • Copier will never ask for overwriting the answers file.
  • Multi-typed choices follow the same type-casting logic as any other question, so it's easier to reason about them. However, if you were using this feature, you might be surprised about its side effects if you don't specify the type explicitly. Just add type: yaml to make it behave mostly as before. Or just don't use that, it's complicated anyway (warn added to docs).
  • Changed --force to be the same as --defaults --overwrite.
  • Copied files will reflect permissions on the same files in the template.

Deprecated

  • Deprecated now and make_secret functions. If your template used those, Copier will emit warnings leading you on how to upgrade it.
  • Templates marked with _min_copier_version below 6 will still default to use bracket-based Jinja defaults, but that will disappear soon. If you want your template to work on Copier 5 and 6, make sure to declare _envops explicitly in your copier.yaml.
  • copier.copy() is confusing, now that actually copying and updating are 2 completely different actions (before, you were actually always updating if possible). Its direct equivalent is now copier.run_auto(), and copier.copy() will disappear in the future.

Removed

  • --subdirectory flag, which was confusing... and probably useless.
  • Lots of dead code.

Fixed

  • A directory that gets an empty name works as expected: not copied (nor its contents).

  • Added pre-commit for enforced linting.
  • Added prettier, black and isort for code formatting.
  • Added pytest for running tests.
  • Use plumbum as CLI and subprocess engine.

[2.5.0] - 2019-06-16

  • Expanduser on all paths (so "~/foo/bar" is expanded to "<YOUR_HOME_FOLDER>/foo/bar").
  • Improve the output when running tasks.
  • Remove the destination folder if the copy process or one of the tasks fail.
  • Add a cleanup_on_error flag to optionally disable the cleanup feature.
  • Add the skip_if_exists option to skip files, without asking, if they already exists in the destination folder.

[2.4.2] - 2019-06-09

  • Fix MAJOR bug that was preventing the _exclude, _include and _tasks keys from copier.yml (or alternatives) to be used at all. It also interpreted _tasks as a user-provided variable.

[2.4.0] - 2019-06-08

  • Empty folders are now copied. The folders are also displayed in the console output instead of just the files.
  • prompt_bool can now have an undefined default (ans answer is mandatory in that case).
  • Reactivates the copier.yml and copier.yaml as configuration files.
  • The new extra_paths argument specifies additional paths to find templates to inherit from.

[2.3.0] - 2019-04-17

  • Back to using a setup.py intead of a pyproject.toml.
  • The recommended configuration file is now copier.toml.

[2.2.3] - 2019-04-13

  • The copier command-line script now accepts "help" and "version" as commands.

[2.1.0] - 2019-02-08

  • Task runner 🎉.
  • Use _exclude, _include, and _tasks keys in copier.yml as the default values for the .copy() arguments exclude, include, and tasks.

[2.0.0] - 2019-02-07

  • Rebranded from Voodoo to Copier!
  • Dropped support for Python 2.x, the minimal version is now Python 3.5.
  • Cleanup and 100% test coverage.
  • The recommended configuration file is now copier.yaml, but a copier.json can be used as well. The old voodoo.json is also supported for now but is deprecated and will be removed in version 2.2.
  • Python package format updated to the latest standard (no setup.py 😵).
  • Renamed the render_skeleton() function to copy(). The function signature remains almost the same, the only changes are:
    • filter_this parameter is now called exclude.
    • ignore_this parameter is now called just ignore.
  • Dropped the idea of storing the templates in a hidden $HOME folder.
