Library and command-line utility for rendering projects templates.

Last update: Jan 04, 2023

Overview

A library for rendering project templates.

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

Installation

Install Python 3.6.1 or newer (3.8 or newer if you're on Windows).
Install Git 2.24 or newer.
To use as a CLI app: pipx install copier
To use as a library: pip install copier

Quick usage

Use it in your Python code:

from copier import copy

# Create a project from a local path
copy("path/to/project/template", "path/to/destination")

# Or from a git URL.
copy("https://github.com/copier-org/copier.git", "path/to/destination")

# You can also use "gh:" as a shortcut of "https://github.com/"
copy("gh:copier-org/copier.git", "path/to/destination")

# Or "gl:" as a shortcut of "https://gitlab.com/"
copy("gl:copier-org/copier.git", "path/to/destination")

Or as a command-line tool:

copier path/to/project/template path/to/destination

Browse or tag public templates

You can browse public copier templates in GitHub using the copier-template topic. Use them as inspiration!

If you want your template to appear in that list, just add the topic to it! 🏷

Credits

Special thanks go to jpscaletti for originally creating Copier. This project would not be a thing without him.

Many thanks to pykong who took over maintainership on the project, promoted it, and laid out the bases of what the project is today.

Big thanks also go to Yajo for his relentless zest for improving Copier even further.

Thanks a lot, pawamoy for polishing very important rough edges and improving the documentation and UX a lot.

Add the ability to customise how questions are asked

Discussed in https://github.com/copier-org/copier/discussions/673

^{Originally posted by pfmoore May 23, 2022} The prompt currently appears to be a 🎤emoji, followed by the help (if specified), then the item name and a format prompt. I'd like to be able to change the prompt as I find it difficult to read (in particular, the format prompt is very distracting, and I'd like to omit it). Is that possible?

Having checked the source code, it seems that this isn't possible. But the questionary library looks very flexible, so it would be possible to do this if there was a way to describe the format in the template configuration. Would such a change be welcome? I'd be more than happy to work on a PR for this, but I'm very new to the project (I'm currently trying to migrate my existing cookiecutter templates over to copier) so I don't know if that's something that would be considered a reasonable feature for the project.

I'd imagine doing this via settings in the copier.yml file, so the format would be decided by the template, rather than by the user. Would that make sense?

feat: questionnaire validation
I'd love a possibility to validate questionnaire inputs. Being able to validate str against regex would already be a huge help, e.g. by specifying a field appropriately in copier.yml:

project_name: type: str help: Your project name validate: ^[a-zA-Z][_a-zA-Z0-9]+$

Add a slugify filter
I cannot think of a template I wrote that didn't need such a filter 🙂

I usually write a very naive one myself:

repository_name: type: str help: Your repository name default: "[[ project_name|lower|replace('_', '-')|replace(' ', '-') ]]"

But it will break in so many cases.

As an alternative, if we don't want to support more and more filters in copier, maybe we could think of allowing custom filters to be used. Take a look at https://github.com/mattrobenolt/jinja2-cli/pull/86, it allows this use of jinja2-cli:

jinja2 -f ansible.plugins.filter.ipaddr.ipaddr test.txt

In copier's case, we would not be able to load the filter using its Python dotted-path, so we would have to think of another way to add it to the Jinja environment.

Autodoc
Issue #173

We use mkdocs to write and build the documentation, with the material theme for mkdocs, as well as the mkdocstrings plugin for auto-documentation of the source code.

I had to remove the doctoc pre-commit hook because I couldn't get its generated tables of contents to be rendered correctly in the documentation (they are a mix of HTML and Markdown). Note that this is not a great loss, as the material theme for mkdocs adds its own table of contents in the right sidebar for every page. We lose the ToC on GitHub only (and it was not really usable either because it's not sticky).

To try it, clone my branch and run poetry run mkdocs serve, then go to localhost:8000.

I could use early feedback on the following TODO points:

TODO:

[x] Improve the code documentation: some modules have no docstrings at all, so they appear empty in the docs. The other docstrings could really be detailed a bit more. We can also benefit from the cross-reference ability of mkdocstrings, linking objects between them to improve navigation in the reference.

[x] Customize the docs? Version 5 of mkdocs-material makes it easier to customize the docs color and icons. I'd be more inclined to let the authors/maintainers of copier do so :slightly_smiling_face:

[x] Split the README (aka overview in the docs) into multiple files? Create a template, generate a project, update a project, etc..., then clean it up (remove API section maybe).

Show diff on conflict before deciding if overwrite or skip interactively

When the user is asked interactively if he would want to overwrite or skip a conflicting file, he has no way to know what's the good answer.

This relies on the expectation that the subproject will be git-tracked and thus the user is able to inspect the diff afterwards. But, if that's not the case (for example a git-ignored file with secrets within), he cannot safely decide.

In the case where it is git-tracked, anyway being able to inspect the diff interactively still seems to be a good UX enhancement.

Refactoring of configuration
This PR cleans and hardens the code base via the following refactorizations:

Untangling the creation of the configuration object from copy_local.

Introducing basic data validation and default handling via pydantic.

Various minor improvements like making flags a class for explicit member access via dot syntax.

TODO

[x] Make tests green.

[x] Add pydantic to dependencies.

[x] Fix type annotations.

[x] Consider moving user_data into sub module to together with conf

[x] General cleanup and removal of dead code.

[x] Add new tests.

[x] Test merging precedence.

`pip install copier` fails on windows

Describe the problem Running pip install copier with python 3.10 fails on Windows when the Microsoft C++ build tools package is not installed. I would prefer not install the heavy (7GB) c++ compiler installed just to use copier.

This seems to be caused by the iteration_utilities package lacking a python 3.10 wheel file in pypi and it doesn't look like they are planning to generate wheel files for python 3.10 any time soon.

To Reproduce

Run pip install copier on Windows with python 3.10 and without visual c++ compiler installed

Internal keys / non-prompted values

Is your feature request related to a problem? Please describe.

Trying to build a template for Terraform structure, which means a lot of the file tree structure depends on one or more of the inputs. Using a "choice" type here makes a lot more sense from a usability standpoint than using multiple competing boolean keys. For example:

Example copier.yaml

flavor:
  type: str
  choices:
    - Docker
    - Instances
    - Kubernetes
    - None

But that means having to do string comparison if-statements in directory names to create conditional directories. And everywhere else when this value is evaluated. If multiple answers are correct for some conditional directories then that results in even longer if-and statements:

Example filetree

.
├── {% if flavor == 'docker' %}ecs{% endif %}
├── {% if flavor == 'kubernetes' %}eks{% endif %}
├── {% if flavor == 'instance' %}bastion{% endif %}
├── {% if flavor == 'docker' or flavor == 'kubernetes' %}portainer{% endif %}
└── {% if flavor != 'none' %}vpc{% endif %}

This can make the directory names quite long and makes everything poorly readable. It also results in a lot of Jinja repetition across the template.

Describe the solution you'd like

I was hoping to create keys derived from the choice key behind the scenes, e.g. without prompting the user for input. In my scenario these would be booleans, but it could also be useful for concatenating strings or other post-input processing purposes that deduplicates a lot of code from the template files.

Example of how I'd love for this to work for my use case:

Future copier.yaml

flavor:
  type: str
  choices:
    - Docker
    - Instances
    - Kubernetes
    - None

# Internal variables
isContainer:
  type: bool
  value: "{% if flavor == 'docker' or flavor == 'kubernetes' %}true{% else %}false{% endif %}"

isDocker:
  type: bool
  value: "{% if flavor == 'docker' %}true{% else %}false{% endif %}"

isInstance:
  type: bool
  value: "{% if flavor == 'instance' %}true{% else %}false{% endif %}"

isKubernetes:
  type: bool
  value: "{% if flavor == 'kubernetes' %}true{% else %}false{% endif %}"

isLite:
  type: bool
  value: "{% if flavor == 'none' %}true{% else %}false{% endif %}"

Future filetree

.
├── {% if isDocker %}ecs{% endif %}
├── {% if isKubernetes %}eks{% endif %}
├── {% if isInstance %}bastion{% endif %}
├── {% if isContainer %}portainer{% endif %}
└── {% if isLite %}vpc{% endif %}

For this to work the value: key would have to be added and if this key is set then prompting the user for input would always be skipped. Alternatively prompt: false could be used in combination with setting the value using default: similar to what was suggested in https://github.com/copier-org/copier/issues/229 before.

If preferred these "internal variables" could also be moved one layer down under an identifier:

flavor:
  type: str
  choices:
    - Docker
    - Instances
    - Kubernetes
    - None

_derived_keys:
  isContainer:
    type: bool
    value: "{% if flavor == 'docker' or flavor == 'kubernetes' %}true{% else %}false{% endif %}"
  isDocker:
    type: bool
    value: "{% if flavor == 'docker' %}true{% else %}false{% endif %}"
  isInstance:
    type: bool
    value: "{% if flavor == 'instance' %}true{% else %}false{% endif %}"
  isKubernetes:
    type: bool
    value: "{% if flavor == 'kubernetes' %}true{% else %}false{% endif %}"
  isLite:
    type: bool
    value: "{% if flavor == 'none' %}true{% else %}false{% endif %}"

Describe alternatives you've considered

I've tried creating the variable like this, but setting when: false doesn't set the variable at all, resulting in the boolean always resolving to true:

isLite:
  type: bool
  when: false
  default: "{% if flavor == 'none' %}true{% else %}false{% endif %}"

feat: include local dirty changes by default. fixes #184
A quick attempt at implementing the changes described in this comment.

if a template is vcs-tracked and dirty, the changes are committed automatically with a "wip" commit and propagated to the subproject

user is warned in this scenario

tests for copy and update on dirty templates

I made this the default behavior, but would be happy to add a flag for this behavior and maintain the current default.

Also, think this will have to rebase off of #519 to pass CI

Answers file templating

Closes #866

This adds support for templating in the _answers_file variable, allowing multiple answers files to be generated depending on answers given in copier.yml.

Was unsure whether to put tests in a new file or tests/test_answersfile.py. Went ahead and made a new file, but let me know if I should put them elsewhere.

uncommited changes only used in template repos without tags
Describe the problem According to this thread: https://github.com/copier-org/copier/discussions/743 copier is supposed to use uncommited changes by default. But it only does so when no tags exist in the template repository.

To Reproduce

mkdir template cd template echo "Hi" > test.txt git init git add . git commit -a -m "1" git tag v0.0.1 echo "Hi2" > test.txt copier copy . /tmp/foo cat /tmp/foo/test.txt

The result is Hi

Fix conflict with commitizen (commit message format)

Problem description

Copier initializes a git repository in the current directory according to github
- While using commitizen as pre-commit-hook, this ~~can be~~ is problematic, since the commit message isn't properly formatted
- Issue gets pointed out in the following code snippet:

# (main.py) 
# _git_initialize_repo(self):
# (...)
# 1st commit could fail if any pre-commit hook reformats code
git("commit", "--allow-empty", "-am", "dumb commit 1", retcode=None)
git("commit", "--allow-empty", "-am", "dumb commit 2")

REQUEST

Add commitizen supported / formatted commit message for initialization

EDIT:

This is what the conflict looks like:

| commitizen check.........................................................Failed
| - hook id: commitizen
| - exit code: 14
|
| commit validation: failed!
| please enter a commit message in the commitizen format.
| commit "": "dumb commit 2"

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.

Python 3.10 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.

In migration scripts, we have the new environment variables $VERSION_PEP440_FROM, $VERSION_PEP440_CURRENT and $VERSION_PEP440_TO, which will always get a valid PEP440 version identifier, without the v prefix, allowing your migration scripts to have a valid standard where to base their logic.

Raise a CopierAnswersInterrupt instead of a bare KeyboardInterrupt to provide callers with additional context - such as the partially completed AnswersMap.

Support for user_defaults, which take precedence over template defaults.

Copy dirty changes from a git-tracked template to the project by default, to make testing easier.

Advertise clearly which version is being copied or updated in the CLI.

Add jinja variable _copier_python to provide python sys.executable.

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.

We keep trailing newlines by default for Jinja 2 templates.

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.

Copier now uses git clone --filter=blob:none when cloning, to be faster.

Removing files from templates will remove them too from the subprojects when they get updated.

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

Minimal supported Python version is now 3.7 (dropped Python 3.6 support).

Removed the json method on _copier_conf. Where you would previously use _copier_conf.json() in your templates, please now use _copier_conf|to_json instead.

--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).

When comparing versions to update, PEP 440 is always used now. This way, we avoid fake ordering when git commit descriptions happen to be ordered in a non-predictable way.

Answers file will only remember answers to questions specified in the questionary.
