Re: Clojure library
Hello Fernando, Please correct me if I've misunderstood. If you want to install one of your libraries locally and are running leiningen just execute: lein install This way you can reference it in other projects just like you would a library from clojars.org.

Re: Clojure library
OK, here is an older library project that uses lein: https://github.com/laforge49/aatree So I guess that covers all the bases. Personally I find boot to be amazing. And easy to use.

Live rendering of AsciiDoc and MarkDown files in Chrome browser (Github Flavored!)
*UPDATE: AsciiDoc vs MarkDown format:* I have been trying to edit some MarkDown files on GitHub, and it seems that the Google Chrome extension AsciiDoctor.js no longer renders MarkDown, only AsciiDoc. Not to worry, however! I just found a similar Chrome extension that does live rendering of Markdown format: Markdown Preview Plus ** Another nice tip: Both Asciidoctor.js and Markdown Preview Plus have an Options panel which allows you to choose "GitHub" styling.very nice! ** Alan On Wednesday, September 2, 2015 at 12:06:23 PM UTC-7, Alan Thompson wrote: > > Hey, > > As you all know, the README files on Github, etc can be formatted using > the either AsciiDoc (my favorite) or the older MarkDown format.

Re: Stable clojure.xml/parse
Are you sure that it changes the child element order? It hasn't in my
experience. Example:
(clojure.xml/parse (io/input-stream (.getBytes
"" "UTF-8")))
=>
{:tag :a,
:attrs nil,
:content [{:tag :b1, :attrs nil, :content nil}
{:tag :a1, :attrs nil, :content nil}
{:tag :a2, :attrs nil, :content nil}
{:tag :a3, :attrs nil, :content nil}
{:tag :a4, :attrs nil, :content nil}]}
Do you have a counter-example? Or are you talking about attribute nodes
maybe?
Also the only parser included with clojure.xml already uses SAX: it just
supplies a content handler that builds the clojure structures
clojure.xml/parse returns.

Re: defmulti is a defonce?
I usually work around this by putting the dispatch in a separate def and referencing the var within defmulti. (defmulti my-multi #'my-dispatch) It's barely slower for the extra var dereference and very convenient for development.

Re: Question about how lazy sequences are held/released/garbage collected
I think this is an example of locals-clearing at work: https://groups.google.com/forum/#!topic/clojure/FLrtjyYJdRU My guess is that the compiler clears the references 'at the point of last reference', but in this case s2 has no last reference.

Question about how lazy sequences are held/released/garbage collected
The problem of correctly handling large lazy sequences so they don't blow up in memory came up at work this week. I thought I would try to explain the following simple case to our Monday afternoon study group, and I realized I don't understand it 100%: (def n 1e8) (let [s1 (range n) s2 (map identity s1)] (count s2)) ;;=> 1 (let [s1 (range n) s2 (map identity s1)] (count s1)) ;;=> GC overhead limit exceeded For the first case, I get that in consuming s2, elements of both s1 and s2 are consumed and garbage-collected; and that in the second case, clearly s1 can't be released as it's consumed because s2 might still need it (even though we never realize s2). My question is, as s1 is consumed in the second case, how does it "know" that s2 still holds a reference to it, and that it therefore should keep the realized values? What is the relevant difference between these two examples? And where in the Clojure/core code are the relevant details? Thanks in advance!

But... I just realized every cell has to be a ref. There are *is* at least one internal model attribute that changes (the status as nascent, alive, dying, or dead) but that could be a ref... I will look at whether I even need models to be refs. Parallelized cells? That would be cool, though for my applications single-threaded has been more than fast enough.
