I'm generating my Knot's config from a Jinja2 template, and I'm having a problem with one thing. For example, if I have a list of elements, [e1,e2,e3,e4], and I want to generate a "groups" config for these based on a condition, and I do:
groups { mygroup { {% for x in list %} {% if condition %} {{ x }}, {% endif %} {% endfor %} } However, this results in a syntax error, because the last element ends with a comma, and then there's a closing bracket. I tried to insert the comma conditionally, by checking to see if it was the last element, but this can also fail if the last element didn't match the condition. So I thought about this ugly hack: groups { mygroup { {% for x in list %} {% if condition %} ,{{ x }} {% endif %} {% endfor %} } Notice that I have the comma *before* each element. This results in an opening brace, a comma, and then the other elements. My supposition is that Knot's syntax parser is okay with this, because it just sees a null first element. If I check this with knotc's "checkconf", it says the syntax is okay. Can I safely use such a config?
