Audio files in the "static/" directory?
1 point by evanrmurphy 5496 days ago | 3 comments
I placed "foo.mp3" in Arc's "static/" directory but was unable to make it play using the HTML 5 audio element as follows:

  <audio src="foo.mp3" controls="controls">
It does play when I have the src attribute pointing to the file on another server. Is Arc capable of serving static audio files?

Ah, I just found fallintothis' comment about patching "srv.arc" so it can serve static JavaScript. [http://arclanguage.org/item?id=10621] Maybe all that's needed is to append those lists with mp3 entries.

I edited the two points in "srv.arc" so they now read:

  (map (fn ((k v)) (= (type-header* k) (gen-type-header v)))
       '((gif       "image/gif")
         (jpg       "image/jpeg")
         (png       "image/png")
         (mp3       "audio/mpeg")
         (text/html "text/html; charset=utf-8")))
...

  (def static-filetype (sym)
    (let fname (coerce sym 'string)
      (and (~find #\/ fname)
           (case (downcase (last (check (tokens fname #\.) ~single)))
             "gif"  'gif
             "jpg"  'jpg
             "jpeg" 'jpg
             "png"  'png
             "mp3"  'mp3
             "css"  'text/html
             "txt"  'text/html
             "htm"  'text/html
             "html" 'text/html
             "arc"  'text/html
             ))))
Unfortunately the audio element still doesn't work. Requests are failing and producing errors like the following at the REPL:

  tcp-write: error writing (Broken pipe; errno=32)

   === context ===
   /anarki/arc/ac.scm:890:13: writeb
   g2758
   g2724

You'll get this error if the browser has closed the connection and isn't reading the data.

One thing to check is what headers are being sent. For example, with the wget utility, you can use the -S option to see the server headers. First look at the response you're getting from the working server, and then compare it with the response you're getting from the Arc server which isn't working.
