This repository provides a complete set of Jinja macros that are kept up-to-date and 100% compliant with CCS Digital Marketplace GOV.UK Frontend Nunjucks macros. Porting is intentionally manual rather than automated to make updates simpler than maintaining an automated conversion routine. A comprehensive test suite ensures compliance against the latest, and every subsequent, CCS GOV.UK Frontend Frontend release.

This project was inspired by the GOV.UK Frontend Jinja Macros project by HM Land Registry and we thank them for their work which has helped with this project.

The following table shows the version of Digital Marketplace Frontend Jinja that you should use for your targeted version of CCS Digital Marketplace GOV.UK Frontend:

Any other versions of CCS Digital Marketplace GOV.UK Frontend not shown above may still be compatible, but have not been specifically tested and verified.

After running pip install ccs-digitalmarketplace-frontend-jinja, ensure that you tell Jinja where to load the templates from using the PackageLoader as follows:

from flask import Flask
from jinja2 import ChoiceLoader, PackageLoader, PrefixLoader

app = Flask(__name__)

app.jinja_loader = ChoiceLoader(
    [
        PackageLoader("app"),
        PrefixLoader(
          {
            "govuk_frontend_jinja": PackageLoader("govuk_frontend_jinja"),
            "digitalmarketplace_frontend_jinja": PackageLoader("digitalmarketplace_frontend_jinja"),
          }
        ),
    ]
)

To use a component in your project templates you must import and call the component macro and pass the relevant options, for example:

{%- from 'digitalmarketplace_frontend_jinja/components/alert/macro.html' import digitalmarketplaceAlert -%}

{{ digitalmarketplaceAlert({
    "titleText": "Your application is complete",
    "text": "You still have 3 unsubmitted services",
    "type" : "success"
}) }}

The options available to each component macro can be found in the original CCS Digital Marketplace GOV.UK Frontend documentation. Since this project is a like-for-like port, the only difference between the Nunjucks examples and their Jinja equivalents is having to quote key names, e.g. 'text' instead of text.

Releases of this project follow semantic versioning, ie

Given a version number MAJOR.MINOR.PATCH, increment the:

• MAJOR version when you make incompatible API changes,
• MINOR version when you add functionality in a backwards-compatible manner, and
• PATCH version when you make backwards-compatible bug fixes.

To make a new version:

• update the version in the digitalmarketplace_frontend_jinja/__init__.py file
• if you are making a major change, also update the change log;

When the pull request is merged a GitHub Action will tag the new version.
