If I insert via the API a URL into a Category description such as [http:something1/project…] but in the future I might want [http:something2/project…] , that is that the referencing url could change or not be the same in future environments, is there a config or option in Discourse to make links more like [{base\_url}/project…], like a way to configure `base_url` as an environment variable that is replaced in all URLs?

I think you can do it with a theme component. There are some examples of how to replace text with a theme component. It would do it in all posts, not just category descriptions, but that’d probably be OK.

EDIT: Actually `/admin/logs/watched_words/action/censor` might do the job for you. You can have a word replaced with another one. I think that it’d work in your links, but haven’t tested it.

@pfaffman that is very interesting so for example I could have `project_url` in say [project\_url/home\_page/…] replaced to `www.projects1` I’ll give it a shot and see if word replacement woerks in [urls][descriptions] or maybe there is another way of defining URLs, just going by base Meta Description format.
