Is there any way to make Clojure's pprint print the record tags for
records? It seems odd to me that Clojure's main printer has evolved
improved support for records over the years, but pprint still prints
records as a plain, untagged map.

This is not for security, just to keep the edn file independent of

Cool library! But i just changed to fipp this morning. I think I will try

What does miser-width mean since you set it to 60?

I'm starting to think that I can just implement this with some macro magic

The code below accounts for partials of the same arity. However, there
might be a better way to do this with clojure.reflect:
(defn print-partial [a-fn]
(let [c (class a-fn)

(map #(vector (.getName %)
Got it. The macro, as is, will displace the print method for the same arity.

That's not going to work, all the return classes of partial are the same
class.

I don't know if this is considered good Clojure, but you could define a
print-method within a macro to set up the normal string representation for
the partial function:
(defmacro partial* [fname arg0 & args]

Thanks for pointing out the ticket, but based on the Description, it falls

You might be interested in this ticket
(http://dev.clojure.org/jira/browse/CLJ-1278) of which this is perhaps one
special case.
I don't know that I necessarily would want the equality semantics; at least
in the case of impure functions the equality does not hold.

Hi,
There has been one thing bugging me for a long time that seems worth it to
fix, and I was wondering if anyone else has had the same problem. I have
enjoyed using Clojure's REPL and embracing a Clojure-style data model for
my app, where everything is a glorified map or vector and there are n
Most probably, your template is a lazy seq and pprint forces its
evaluation, which is why the error happens at the pprint point.

Aside from the original problem: pprint already prints to *out* and only
returns nil, so the code above first prints template, and then the
println will also print the nil returned from pprint.

Oh, I see. I had just changed :admin-text to hold a keyword instead of
text. I should have seen that sooner.
But I am still confused why a keyword would cause pprint to throw an

Hi Laurent,
I think that pprint might be a good foundation for what you are doing,
but there are a couple of issues that need to be dealt with first.
First, pprint works directly on Clojure objects and not strings, so
the code will need to be read first.
Second, the Clojure reader is lossy

command-line / whatever utility for mass source code reformatting ...
So what is my question ? :-)
Do you know if pprint lib now is (or will in a near future) be able to
handle this use case : that is not only formatting clojure code
returned by the reader, but also clojure code as str
