Re: ClojureScript: how to call a js method when you have the method-string?
It seems you're refering to CLJS-353 - besides supporting a possible Lua backend, it also feels semantically cleaner not to overload array and object access - I'd vote for an additional oget/oset or obj-get/set. Also, the aget and aset interface have this multi-dimensional support thru the signature: ([array i idxs] …), and it's hard to imagine multi-dimensional property access on an object… (btw, unless I'm mistaken, the multi-dimensional array support hasn't been implemented yet for make-array and therefor the aget ([array i idxs] …) implementation doesn't work - can't find a JIRA issue for that) -FrankS.

Re: A/B testing in Clojure?
I was thinking of something along the lines of django-lean ( https://bitbucket.org/akoha/django-lean/wiki/Home) - clean perhaps :) I haven't implemented any A/B testing yet so I just wanted to get a feel for what other people are doing. The silence seems to indicate that people aren't! Having seen recent discussions about Rails, I can see that that the framework approach is not popular in the community so a library seems to be the way to go. I'd definitely be interested in putting something together. Time is a bit tight over the next month but I can do some then things free up. Have you any experience in implementing A/B testing? I've been doing some reading and can pass on some pointers to resources if that would be helpful.

Re: Correct usage of data-readers
when I wrote a tag out, I did the same as Justin in his ordered lib, (defmethod print-method OrderedSet [o ^java.io.Writer w] (.write w #ordered/set ) (print-method (seq o) w)) so the tag is defined by this library and has specific meaning in the data written by this lib. A matched reader is a probably a good idea. This definition of print-method already causes possible conflict or loss of information it another lib uses the same tag. Library writers need to be aware of this and namespace appropriately. Alternatively, library writers must not implement print methods or must implement them in a way that can use an end-application developer defined tag. I suppose that there is no reason why you could not read the tag above into a different type or implementation as long as you understood and honoured the semantics intended. In this sense, the tag is not dissimilar to a named contract (or interface). The more common case would probably be to re-read what had been written. Perhaps this should be the default. With an option to change if you really wanted to. I wasn't aware of the namespace possibility so the idea of library tags does not seem unreasonable.

Re: Correct usage of data-readers
I had assumed that including data-readers.clj in a library was ok... I hadn't considered the issue of clashes with an application. Maybe some tags are intended to be concrete, and some abstractions. If you are defining a concrete tag, then including data-readers is ok, and clients just have to get used to only being able to redef them at runtime. If your tag is designed for read-time redefinition in an application, then perhaps you shouldn't include data-readers? I agree that some guidance would be welcome. -- Dave -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Interest in Scribble for Clojure?
Gary Johnson gwjohnso at uvm.edu writes: I see. After taking a closer look, I can see that you could do LP in Scribble (Yeah, but again -- that's really not its main goal.) as well as also outputting some different kinds of documentation formats, such as Javadocs or standalone documents. The downside I'm seeing is that this all has to be programmed in Scheme Um, it is very intentionally a documentation system that is built on a proper langugae -- like latex and N other such language, only using a general langugae instead of the usual half-baked things... (I know that some people would consider that a disadvantage, and in that case you should definitely go with some non-language tool like markdown, (raw) markup, or some WYSIWYG thing.) and that you may have to do some IMO less than attractive backquoting to get at the underlying LaTeX if you want PDF outputs which use some of the existing LaTeX packages (math libs come to mind). That's almost never needed -- and when it is, it's generally an indication that some rendering feature should be added. At the scribble syntax level, the syntax is very lightweight, so that there's no issues of bad backquoting. I describe all of that in http://barzilay.org/misc/scribble-reader.pdf, and it's applicable to other languages -- not even sexpr-ish ones. My hope is that this can easily provide a proper language syntax for having lots of text. Markdown is another approach, but IME it suffers greatly when you get to unexpected corner cases (eg, non-trivial and non-uniform rules when you want to write some texts), and in other cases it starts simple and end up being horribly complicated (as in wikipedia source files, which started as a simple markdown thing, and now have a ton of conventions as well as a templating systems that require a wikipedia black belt if you get close to it.)

Re: Clojure turns 5
The one thing that has excited me the most about Clojure, is how it blends old and new ideas so well. Clojure is a language based ideas originally created in 1958. It runs on a VM created in 1990. It has a concurrency model never seen before, and it's data structures are based on concepts created in 2000. Clojure really is the best of the last 54 years of computing crammed into one language that's so small that a person can read through the entire source code in a few weekends. When I hear the word abstraction I think of Clojure. When I think of simplicity, I think of Clojure. When I think of concurrency, I think of Clojure.

Re: Midje popularity?
Are you implying that some people doesn't use Emacs? Heretic! Seems like there are a bunch of people interested. The features I am considering at the moment is: Making check-fact refer to actual linenumbers instead of [no-source]:3 or whatever. Migrating from comments to some other sort of marker.(raise your hand if you have commited test results...) Doing a buffer for check all tests in project and show the result. Probably with rerun when watched files changes. It might end up in a total rewrite. Or me working too much at my daytime job... We will see.

Minderbinder is a Clojure library for defining unit conversions available

Examples
Minderbinder includes unit conversions for the following units of measure:
* [Time][t]: via `#unit/time`, base is `:milliseconds`, ns is
`minderbinder.time`
* [Length][l]: via `#unit/length`, base is `:meters`, ns is

(ns minderbinder.test.core
(:require minderbinder.time))
(== #unit/time [1 :second]
#unit/time [1000 :ms])
;;= true
(== #unit/time [1 :minute 30 :seconds]
#unit/time [90 :seconds])
;;= true
Using Minderbinder's unit parse functions
-
(ns minderbinder.test.core
(:require [minderbinder.length :as mbr]))
(mbr/parse-length-unit [1 :km])
;;= 1000
(mbr/parse-length-unit [1 :ramsden-link])
;;= 381/1250
Defining custom conversion rules
Defining a unit conversion is accomplished via Minderbinder's
`defunits-of` macro. The body of the macro expects the following structure:
(defunits-of *unit-name* *base-unit-tag* *docstring* *conversion-spec*)
The *conversion spec* part of the body currently allows pairs of mappings
defined in reletive terms. The pairs always start with a keyword used as
the unit tag. However, the right-hand side of the pair can be one of the
following:
1. Number - defines the value of the unit relative to the base unit
2. Vector - defines the value of the unit relative to another contained
unit
3. Keyword - defines a single alias for a unit
4. Set - defined one or more aliases for a unit
A simplified version of Minderbinder's length conversion definition serves
as an example:
(defunits-of length :meter
The meter is the length of the path
traveled by light in vacuum during a
time interval of 1/299,792,458 of
a second.
:m :meter ;; an alias for the base unit
:km 1000 ;; a larger value relative to the base
unit
:km #{kilometer kilometers} ;; multiple aliases for a unit
:cm 1/100;; a smaller value relative to the base
:mm [1/10 :cm]) ;; a value relative to another unit
### Generated vars
The `defunits-of` macro will define three things in the namespace where
the `defunits-of` macro appears:
1. `parse-XXX-unit` - a function that parses the unit vector according to
the conversion spec, returning the total value relative to the base.
2. `unit-of-XXX`- a macro that allows the for `(unit-of-XXX 1 :foo)`
that returns the total value relative to the base.
3. `XXX-table` - a map describing the unit conversion rules.

Re: ANN: LispIndent, jEdit plugin that indents lisp code
Not currently, no. I'm not really sure how to detect when to use 2 spaces, and when to align arguments. I also feel that no editor really has nailed it, when it comes to deciding that.

Frink is a general purpose programming language, so by default I get that for free via Clojure. ;-) Seriously though, this is in no way meant to replicate the Frink experience of first-class units of measure. Instead the ultimate goal is to allow unit-aware syntax with tools to ensure a common reference base. I will likely add (and will accept patches for) more unit types as time goes on.

Coming from Common Lisp to Clojure
I do hope this is an appropriate topic. I am very excited by the power and capability in clojure and amazed at the rapid quality of tooling that exists so early in the projects life. I would like to admit that i am feeling like the simplicity and elegance that I experienced writing in lisp seems to be bypassed in certain areas in favor of extra syntax [] and what seems to be local variable declarations as well as 'many ways' to do something around looping and recursion. I am wondering how others feel about this and if there are any style guides that i could be exposed to so that I can enjoy the poetry that I may be missing. Could some one help me with this please?

Re: Cdr car
This works just fine, and as you would expect from Common Lisp: user= (cons 1 '()) (1) Clojure does not have improper lists as Scheme and Common Lisp allow. You can't have a cons pair of arbitrary pairs of things, but you can create vectors of 2 arbitrary things if you want such a pair. There aren't cons cells in Clojure. There are lists, and while some are implemented via things that look a lot like cons pairs under the covers, some are not (e.g. chunked sequences are implemented differently, I think). They still act like ordered sequences using the functions available to access them, and most of the time there isn't much reason to care how it is implemented under the covers. There is no mutation on the lists, either. That is a much bigger difference from Common Lisp and Scheme to Clojure. Most Clojure data structures are immutable. No (setf (car my-list) ...). No setf. Instead you make new data structures that are like existing ones, but with changes to them (like a new first/last element, or a new key/value pair in a map).

Re: Coming from Common Lisp to Clojure
Hi I don't know about style guides, but I can recommend to look to 2 books: The Joy of Clojure Clojure Programming - they provide a lot of interesting information, including tips on writing idiomatic Clojure code On Wed, Oct 17, 2012 at 8:14 PM, Curtis cur...@ram9.cc wrote: I do hope this is an appropriate topic. I am very excited by the power and capability in clojure and amazed at the rapid quality of tooling that exists so early in the projects life. I would like to admit that i am feeling like the simplicity and elegance that I experienced writing in lisp seems to be bypassed in certain areas in favor of extra syntax [] and what seems to be local variable declarations as well as 'many ways' to do something around looping and recursion. I am wondering how others feel about this and if there are any style guides that i could be exposed to so that I can enjoy the poetry that I may be missing. Could some one help me with this please?

Re: Midje popularity?
Hi Brian. No need to apologize, you are doing this in your free time. It's highly appreciated whatever we can get. Just to clear something up: Are you maintaining midje-mode? I thought it was Dmitri? That's where I left my pull request anyway. Bruce: I haven't actually used clojure-test-mode, but it certainly seems to fit my requirements. Will see what I can do about that.

Re: Cdr car
My first lisp was UCI lisp in the 80s. There were not many data structures available aside from linked lists and trees. Of course a computer as powerful as today's pocket calculators would have required an entire building if built with the available technology in these years. I used common lisp later in the late 90s and at the turn of the new millennium which was better but linked lists were still heavily used. Clos never really tempted me and today my immune system is very sensitive when the OO level increase too much in my surroundings :) Too much exposure to Java possibly, it's like being allergic, everything goes fine and one day your immune system decides that this stuff you have been immersed in for years is now an enemy to fight. I never missed the cons cell and it's neighboring fns, car,cdr,cadr,caddr, ... when I started toying with Clojure. There are much more interesting data structures available to make use of. I reluctantly use defrecord and avoid deftype these days. My data world today is made of vectors, maps, sets and a bit of lists, all persistent of course. No nostalgia of the linked list in my case :) Luc I came to Clojure from a similar background and posted my thoughts of car, cdr, and cons here http://software-ninja-ninja.blogspot.com/2011/08/clojure-patterns-cons-car-and-cdr.html On Wednesday, October 17, 2012 1:10:15 PM UTC-6, Jeff Heon wrote: If I may suggest the following presentation: http://blip.tv/clojure/clojure-for-lisp-programmers-part-1-1319721 http://blip.tv/clojure/clojure-for-lisp-programmers-part-2-1319826 There used to a transcript available on the newsgroup until Google decided to remove all files from newsgroup 8) On Wednesday, October 17, 2012 2:16:01 PM UTC-4, Curtis wrote: Cons seems to be strange How do i use Cons with an atom to make a list?

Re: ANN: LispIndent, jEdit plugin that indents lisp code
The plugin has been updated to support function argument indenting. It is configurable in the plugin options. Next, I think I will implement presets. The idea is that each preset corresponds to one language. That way, LispIndent can still be language-independent. Users will also be spared of implementing their own regexes. :) What do you think about this?

code design in clojure
I'm finding the books on clojure to be very focused on low-level language features. Are there any good references for how to design code in clojure (or perhaps in functional languages more generally)? For example, knowing when to use a data type or a protocol, knowing when and how to separate purely functional code from code with side effects, making use of monads, queues, and the other forms that one hears about in the forums, etc. -- You received this message because you are subscribed to the Google Groups Clojure group.

Oooh, this is nice. :) I selected the indent to function arguments by default radio button, checked the box to indent if operator matches and filled in defn, and indenting works wonderfully so far. Will try this out some more. Next, I think I will implement presets. The idea is that each preset corresponds to one language. That way, LispIndent can still be language-independent. Users will also be spared of implementing their own regexes. :) What do you think about this? Oh, do you mean having that indent two spaces if operator matches text box pre-filled when selecting a given lisp-like language? That would be great, and would save users a lot of time having to figure out what should go in there while they're learning the language. :) Great stuff here.
