How to specify Content-Type ?

[rapenne-s]

I have some problems related with Apache + mod_lisp because not content-type is defined, or serving RSS feed not served as a XML or stuff like that.

How can I specify the content-type of a response ? I have seen that it is possible to do it in Clack, but I don't understand how to access it from caveman.

You can use caveman:*response* in controller functions. It is a response object of caveman.response:<response> which is a subclass of clack.response:.

(setf (clack.response:headers *response* :content-type) "application/rss+xml")

Thank you for your precise answer, it works great !

Would you merge a pull request if I add some documentation to caveman ?

[fukamachi]

Sure :)

I'm aware that the documentation isn't enough. I'll appreciate your contribution.

Hi, I've got two ideas:

• wouldn't it nice to have a special annotation to specify content type of the function results, somewhere after the @ignore params (in the function body preamble) is placed:

@url GET "/names.json"
(defun get-names-json (params)
  @content-type "text/json"
  ....)

But let the setf way of altering the content type for special cases.

• I think that in order to assist in documentation writing and collecting useful tips it would be nice if you created (initialized) project Wiki. In order to do so just edit the welcome page so that the wiki gets created and others will be able to edit it without editing project sources.

Thanks!

As far as I understand this annotation might be defined somewhat like:

(defannotation content-type (mime)
  (:arity 1)
  `(setf (clack.response:headers *response* :content-type) ,mime))

Please include it (if it is correct) and you find it useful as well. Thanks!

This would be a very nice addition !
