My variables are not replaced in the output

[taurr]

This entry has been made to answer a repeating question in the issues section.

When handling certain files, e.g. Github Workflow yaml files, it seems that cargo-generate does not replace variables with their value.

[taurr]

Reason

If the file in question is e.g. a Github Workflow yaml file, it may contain the Github variable syntax:

${{ github-variable }}

This conflicts with the Liquid syntax which is:

{{ liquid-variable }}

As Liquid can't tell the difference, it actually tries to substitude the Github variable. It fails and just leaves the syntax in the file. It actually fails handling the file entirely - it even fails at notifying cargo-generate that there were an issue.

Solution 1

One way to solve this issue, is to use the following Liquid syntax:

${{ "github-variable" | prepend: "{{" | append: "}}" }}

Solution 2

Another way is to use:

{% raw %}
${{ github-variable }}
{% endraw %}

@taurr Thank you so much. This workaround works perfectly for me and I'd be happy to write a section in the FAQ/Cargo Generate Book to clarify this. Thank you for all the hard work.
