Is there a way to tell Dr Jekyll this?
{% assign filename = site.data.whatever.variable.i.want %}
{% if exists {{ filename | downcase }} %}
<p>File exists</p>
{% else %}
<p> No file here</p>
{% endif %}

I think you just skip the double-braces?
Jose Costa Teixeira (Feb 18 2021 at 21:15):
if I do this
{% if exists filename %}
I get this exception
Unknown operator filename

seems the issue is finding if a file exists. @Eric Haas do you know if that is possible?
Eric Haas (Feb 19 2021 at 21:51):
I could never figure how to check if file exists in Jekyll/liquid. for some files types like fixed assets you can, but never found it very useful.

see https://stackoverflow.com/questions/16528783/check-for-existence-of-file-using-jekyll

It would be easier to cycle through the ig resource for pages or one of the site variables or created your own list of files in the data directory.
