is there any way to return a clojure function as a string? I am making some online documentation and I would really like to be able to add code into the html by somehow evaluating a function into text.

thanks

  • the problem I had in googling for the answer was that everything I found was about literally returning strings not the code of a function as a string. Commented Mar 9, 2012 at 23:46

Take a look at the source-fn function from the clojure.repl namespace:

Usage: (source-fn x)

Returns a string of the source code for the given symbol, if it can find it. This requires that the symbol resolve to a Var defined in a namespace for which the .clj is in the classpath. Returns nil if it can't find the source. For most REPL usage, 'source' is more convenient.

Example: (source-fn 'filter)

Thanks a lot. (source) was exactly what I needed! Seems obvious now of course ;)
just kidding, source uses print where as source-fn returns the string I needed. thanks again
Links don't work anymore.
