Alan Kay talk
Alan Kay gave a very interesting talk which I think the Clojure community might find enlightening. Specifically, near the end he talks about building a DSL by careful domain analysis. http://tele-task.de/archive/video/flash/14029 In relation to Clojure, are there lessons to learn from the Meta language he mentioned? Does anyone have references to it? His example from the talk deals with writing down the equations of graphics primitives in a mathematical way and then deriving executable code from the math. In the area of parallel and concurrent programming we have some equations that might form a basis of a mathematical formulation. See Parallel Program Design: A Foundation by K. Mani Chandy and Jayadev Misra Could we write the mathematics of ACID and STM and then derive correct, small implementations? Alan Kay makes a compelling argument that this could change the game.

Re: lein-exec 0.2.0 – Scripting in Clojure
Hi John, Useful blog post, thanks! Thanks! I've been using lein-oneoff for this. What are the differences between lein-exec and lein-oneoff? Current latest versions of lein-exec (0.2.0) and lein-oneoff (0.2.0) have some overlap, but let me list few differences AFAIC: 1. lein-oneoff works with Lein 1.x, lein-exec works with Lein 2 2. lein-oneoff can start up REPL, which is rather cool. lein-exec cannot. 3. lein-oneoff can start up swank, lein-exec doesn't know about swank 4. Let's say we have a file hello.clj with content as follows: (println Hello World!) How long does it take for lein-exec and lein-oneoff to run it? This is what I got: tmp shantanu$ time lein oneoff hello.clj Hello World! real0m5.935s user0m15.050s sys 0m0.795s tmp shantanu$ time lein2 exec hello.clj Hello World! real0m2.115s user0m6.809s sys 0m0.277s I think the improvements may be due to Leiningen 2. 5. lein-exec supports piping, not sure about lein-oneoff (I couldn't figure out a way to.) 6. lein-exec can work both with and without project-context. lein- oneoff works only without project context. This capability is new in Leiningen 2. 7. In lein-oneoff you specify all dependencies in the beginning using #_(defdeps ..). In lein-exec you are free to pull in dependencies at any point in the code. 8. lein-oneoff doesn't preserve the name of the script in *command- line-args*; lein-exec does. Hope that helps.

Re: Embed clojurescript literals in server response
I would like to evaluate other methods which may involve:
-parsing hidden strings in the html code
The way that I've been doing this, for better or worse, has been to insert
a Javascript function call into the HTML output by my server, like:
script type=text/javascript
$(function() {my_cljs_ns.initialize('data');});
/script
Where 'data' is some clojure datastructure that has been run through pr-str
and had single quotes escaped. The clojurescript function called by the
generated javascript has to be marked with :export to make this work. When
called, it calls read-string on its first argument.
This seems more or less equivalent to just using a hidden form field. I
don't really see much of an advantage either way. This approach has been
working great for me so far.
-compiling or retrieving from cache, javascript code generated from
clojurescript serverside with the data literals in javascript form already,
no parsing of clojurescript needed.
Why are you trying to avoid parsing the clojurescript client-side? Are you
working with a very large data structure? Dynamically compiling the form
to javascript on the server side is going to be very expensive, although I
guess if it's very cache-friendly it might work out well.
Be aware that if you're using the compiled clojurescript approach, and are
using advanced optimizations, that you'll need to make careful use of
:export and possibly even :externs to make the pre-compiled and
dynamically-compiled javascript work together.
Using the pr-str/read-string approach is likely to be *much* simpler than
this, and is definitely the approach I'd recommend.

Re: Disable name mangling for 'static'

Nice!
The workaround I'm currently using is
(.use app (js* require('express')['static']('public')))
(the closure compiler wont allow require('express').static ... )

Re: Embed clojurescript literals in server response
script type=text/javascript
$(function() {my_cljs_ns.initialize('data');});
/script
Today I coded up a method. Currently I'm creating divs of a class that is
invisible. Then I just use some node searcher to grab the content then call
read-string on it. Seems easier to do then inserting the javascript
function call as you are doing, but my method involves more computation
(probably very negligible). It's simple and it works.
(ns foo (:require [goog..]) (:require-macros [enfocus.macros :as em]))
(defn node-raw-text [selector]
(let [store (atom)]
(em/at js/document
selector
(fn [node]
(reset! store (goog.dom/getRawTextContent (first node)
@store))
;; then later you can call something like so
(reader/read-string (node-raw-text [:div#default-cljs-data]))
Why are you trying to avoid parsing the clojurescript client-side? Are
you working with a very large data structure? Dynamically compiling the
form to javascript on the server side is going to be very expensive,

dynamically-compiled javascript work together.
Basically, I want to see what's possible. If someone's done the research on
how to do it this way, I'd like to see it. There's a different trade-off
being made with each method.
