They sent a slamhound on Turner's trail in New Delhi, slotted it to his pheromones and the color of his hair. It caught up with him on a street called Chandni Chauk and came scrambling for his rented BMW through a forest of bare brown legs and pedicab tires. Its core was a kilogram of recrystallized hexogene and flaked TNT. He didn't see it coming. The last he saw of India was the pink stucco facade of a place called the Khush-Oil Hotel. Because he had a good agent, he had a good contract. Because he had a good contract, he was in Singapore an hour after the explosion. Most of him, anyway. The Dutch surgeon liked to joke about that, how an unspecified percentage of Turner hadn't made it out of Palam International on that first flight and had to spend the night there in a shed, in a support vat. It took the Dutchman and his team three months to put Turner together again. They cloned a square meter of skin for him, grew it on slabs of collagen and shark-cartilage polysaccharides. They bought eyes and genitals on the open market. The eyes were green. -- Count Zero, page 1. By William Gibson
Slamhound rips your ns form apart and reconstructs it. No Dutch surgeon required.
Install it as a Leiningen plugin:
$ lein plugin install slamhound 1.1.1
Take a namespace with a sparse ns form that won't compile:
$ cat src/my/namespace.clj # before: ns form is missing clauses (ns my.namespace "I have a docstring.") (defn -main [& args] (pprint args) (io/copy (ByteArrayInputStream. (.getBytes "hello")) (first args)))
Then run slamhound on it:
$ lein slamhound src/my/namespace.clj # after: spits out new ns form (ns my.namespace "I have a doc string." (:use [clojure.pprint :only [pprint]]) (:require [clojure.java.io :as io]) (:import (java.io ByteArrayInputStream)))
For large projects, it can be slow to re-run from the command-line since it has to load every namespace for every invocation. Leiningen's interactive task is one way to mitigate this:
$ lein int Welcome to Leiningen. Type help for a list of commands. lein> slamhound src/my/namespace.clj [...]
The first run will be slow, but successive runs will be quick.
You can do it manually from the repl too:
user=> (use 'slam.hound) nil user=> (println (reconstruct "src/my/namespace.clj")) (ns my.namespace "I have a doc string." (:use [clojure.pprint :only [pprint]]) (:require [clojure.java.io :as io]) (:import (java.io ByteArrayInputStream)))
src/swank/payload/slamhound.el allows for
convenient access within Slime sessions via
M-x slamhound as well as
running it over an entire project with
You can install manually, but if you use
M-x clojure-jack-in with
Swank Clojure 1.3.3 or newer to launch your Slime session then it will
be loaded into Emacs automatically.
Slamhound can only rebuild your namespace if it follows the rules and
doesn't do anything too fancy. If your code depends upon a
clause, the required namespace must be aliased
:as the last segment
of its name. Referring to fully-qualified vars is not supported. The
only supported option to
- Better pretty-printing
- Allow for custom disambiguator functions
