Our special page suggests a missing end-tag on this page we use to access an archive by year. The page is mainly a transclusion of this single archive page, that contains no errors. Using lintHint 0 errors are reported for this original page and 4 for the transcluding page! As far as I can see, 3 error messages are generated by the "{{qtu}}" in section 66.1 and 1 by section 79, a WMF message. As there seems to be no problem rendering the page as intended, might this be a bug in Linter?
Topic on Extension talk:Linter
I have narrowed down the problem to our template: Tl that is used to create a link to a template (description) page, and uses html-entities instead of {}-brackets in order to achieve the desired result. For Linter this is no problem on the page itself, but when the page containing the template is transcluded itself apparently it becomes too much. My question now becomes:
a. Will using the html-entities in the way our template Tl become problematic in future parsers? In that case it would constitute a new error?
b. If the answer to a. is "No!", then isn't this a bug to be fixed in Linter?
Chances are that it isn't a false positive. The problem probably comes from the hacky way you're trying to display the templates, since it ends with }}. It means that if there is another template on the page it will complete the transclusion and have unexpected results, e.g.:
{{ecologie|{{Tl|foo}}
A more sensible approach is to either apply nowiki to each side, or replace all curly brackets there with their html entities:
{{templatename}}
Thanks for the reply and the suggestion. As far as I am concerned my question has been answered and the problem is solved.
