Re: Multiple key-value pairs in assoc-in (old issue)

[Andy Fingerhut]

Of course you can copy the newer definition of assoc-in into your own projects 
and use it if you like, but that probably doesn't prevent your little bit of 
sadness.

'lein trampoline test' fails on first run with 'No implementation of method'

[Brian Craft]

With an empty target directory 'lein trampoline test' fails with a protocol 
exception, 'No implementation of method'.

Running 'lein test' works fine. After running 'lein test', 'lein trampoline 
test' also works.

Anyone know what's going on? Seems like something isn't being compiled, or 
loaded, but I don't know why.

Re: grouping and mapping

[Steve Miner]

Sorry, I got the semantics of the grouping-fn wrong.  My code assumes that the 
key is always first in the elements and my grouping is more like a merging-fn.

Re: grouping and mapping

[miner]

If your data elements are essentially map-entries (key-value pairs), I'd 
use reduce.  Maybe something like this would work for you...

(defn mapping-group-by [grouping-fn mapping-fn coll]
  (reduce (fn [res [k v]] (update res k grouping-fn (mapping-fn v)))
  {}
  coll))

(def foos [[:a "foo"]  [:b "bar"]  [:a "baz"]])

(mapping-group-by conj clojure.string/upper-case foos)
;;=> {:a ("BAZ" "FOO"), :b ("BAR")}

If you need vector values, you can wrap `conj` with `fnil` to get a vector.

(mapping-group-by (fnil conj []) clojure.string/upper-case foos)
;;=> {:a ["FOO" "BAZ"] :b ["BAR"]}

grouping and mapping

[Nathan Smutz]

Just to put the basic Clojure out there:

(->> (group-by first foos) 
 (map (fn [[key col]] 
  [key (mapv (comp clojure.string/upper-case second) 
 col)]))
 (into {})

Kudos to Moe,Christopher and Simon.

[ANN] Automatic Clojure Type Annotations

[Ambrose Bonnaire-Sergeant]

Hi,

Happy to announce a new open-source Clojure tool
to generate core.typed type annotations from tests. It's part of a
new crowdfunding campaign

I'm running, read on for details!

# What is it?

This tool infers top-level annotations by instrumenting
your code, running tests, and finally inserts inferred
annotations directly in your source code.

Here's a quick gif

demonstrating
the tool.

You can read more about the ideas behind the tool here
.

# Prototype: Write Tests, Get Types!

The latest core.typed release contains a
prototype for Automatic Annotation inference.

Try it out here !

# Crowdfunding

I am running a crowdfunding campaign

to support
Automatic Annotations for Typed Clojure. The money
will help me keep working on Typed Clojure and travel
to industry conferences.

I will be writing more about how this tool works, and
the general applicability of the infrastructure its
based on.

For example:
- clojure.spec generative tests can help generate type annotations, and
- the infrastructure could even be repurposed to generate clojure.spec
specs!
- mutually recursive map structures can be inferred
- ideas for polymorphic inference

There are only 7 days left and we need $7,500 to
reach our goal. Please help by contributing!

Thanks for your support!
Ambrose
