interpolate links?

[johnjelinek]

(audio :controls "controls"
           (source :src (text "~{rpc/get-song}") :type "audio/mpeg")
           (text "Your browser does not support the audio element."))

yields

<audio controls="controls">
  <source src="[object Text]" type="audio/mpeg">
  Your browser does not support the audio element.
</audio>

How can I get this value into the src property?

Hi John,

There isn't an explicit implementation of the do! multimethod in Hoplon for the src attribute currently. However, there is an :attr method you could use like this:

(source :attr (cell= {"src" rpc/get-song}))

Alternatively, you could implement a do! method for handling :src yourself. However, I think this would be a handy addition to Hoplon. It's kind of weird we don't have it already :-)

@micha what do you think?

(source :attr (cell= {"src" rpc/get-song}))

worked :)

Do you want me to close this or should it remain open until you hear back from @micha regarding a do!?

Hi! You could also do this, if you prefer:

(source :src rpc/get-song)

D'oh! What I said about :src currently going unhandled by do! is wrong - :src falls through to ::default which defers to the :attr implementation.

The reason your original code didn't work is because text returns an HTML TextNode with a reactive text content, not a cell. Since the TextNode isn't a cell, str is called on it to obtain "[object Text]" instead of :src being wired reactively.

Please close this if this makes sense and you accept my apology for confusing the issue :smile:

cool, thanks for the update!
