My recommendation is just that your default approach should be to avoid using them unless you have tried very hard to achieve your goal with pure functions first, and convinced yourself that it isn't possible. Macros are only *needed* IMHO when one of the following applies: - You want to create new language/DSL syntax that isn't expressible with normal function application rules (e.g. short-circuiting evaluation, new control structures etc.) - You need to do custom code generation at compile time for some good reason (e.g. performance, since macros enable you to do compile-time specialisation of code) I wrote about these and gave some examples in a blog post a few months back for anyone interested: http://clojurefun.wordpress.com/2013/01/09/when-do-you-need-macros-in-clojure/ On Thu, Aug 8, 2013 at 9:58 PM, Jace Bennett jace.b...@gmail.comwrote: Thanks, Mike.

Prefer writing pure functions (without side effects) - these are easier to reason about, easier to test, simpler to write correctly and easier to plug together / compose via higher order functions. For example, in your endpoint example I would probably just use three functions: - a pure add endpoint metadata to an endpoint map function - an impure update endpoints function that updates endpoints using an endpoint map - a function that calls both of the above to declare and launch a new endpoint There might be a few other helper functions as well but hopefully you get the idea.

When starting on almost any moderately scoped effort, I quickly run into a class of problems which I think may be a fit for macros, but I want to understand what is the idiomatic way to approach them in clojure. Most of my professional experience is in .NET, and that is probably coloring my thought patterns a bit. In that context, I often use reflection scans and type metadata to configure infrastructural bits and dry things up. Instead of having to explicitly register components in the more dynamic areas of my app, I use conventions to select components to register from the metadata I have about my code. I can imagine using macros in clojure to accumulate metadata about my declarations so that I can query them at runtime. For example, maybe a defendpoint macro that sets up a handler AND adds it to the routing table (or more directly an endpoint map which I then use to make routing decisions among other things). Admittedly, something about the sound of the phrase it's just data tells me I'm sniffin up the wrong tree here. But I don't know how to turn that nagging feeling into working code. Is this a reasonable use of the macro? What about doing the registration at macro-expansion time vs emitting runtime code to do it? How should one approach the problems space otherwise?

I'll also take this opportunity to note that if one has an earlier self-install in place, downgrading can be accomplished by replacing the lein script with the version from the appropriate tag in the Leiningen repo: $ cp /path/to/source/of/leiningen git checkout 2.1.3 cp bin/lein ~/bin Or go to GitHub and download manually in absence of a local clone. This works at least in Linux; hopefully adjusting paths (and the script name on Windows) would make it work on other platforms.

This has been a repeated problem over the last several releases. Mac and Windows users have been s.o.l. each time until it is resolved. None of these problems have had anything to do with SSL. It's been two things: the self-install function was moved, and the S3 ACL was incorrect due to a typo while uploading. The S3 issues are being addressed by ensuring more of the Leiningen team has access to the AWS account; the reason I'm waiting for the 2.3.1 release is that I want to find a time when I can step through it with one of the other contributors so they are familiar with the process and can do it when I'm not around. The self-install was broken such that the implicit self-install happened before HTTP_CLIENT was set. The explicit self-install command happens later if you're running it from a checkout of Leiningen itself, which must have been the case when I was testing. Anyway, a new download location wouldn't solve either of these issues. In the mean time I've reset the stable branch back to 2.2.0, so upgrades and new users won't be affected. If you want to use 2.3.0, you can export HTTP_CLIENT and run `lein upgrade 2.3.0` specifically and it will still pull it in. You can always back out of an upgrade by running `lein upgrade 2.1.3` or whatever; the upgrade command doesn't care which direction it's going. -Phil -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [Proposal] Simplified 'ns' declaration
How does gen-class etc. fit into this new (ns) world?
I'm not sure. I've stepped away from this thread (and the mailing list in
general) for a bit to focus on the mounting amount of work I have to finish
before the deadline hits, so I haven't had much more time to think about this,
and I'm also not very familiar with :gen-class.
Looking at the example in The Joy of Clojure, my first impression is that
:gen-class looks like one hell of an ugly beast by itself:
(ns joy.gui.DynaFrame
(:gen-class
:name joy.gui.DynaFrame
:extends javax.swing.JFrame
:implements [clojure.lang.IMeta]
:prefix df-
:state state
:init init
:constructors {[String] [String]}
:methods [[display [java.awt.Container] void]
^{:static true} [version [] String]])
(:import ... ))
Looking at that, I think most of it can be kept as-is, except perhaps for the
sake of supporting both versions of ns it might be worth turning the outer
parenthesis into brackets. Also, what is the purpose of the :name keyword? Are
there legitimate situations where you'd want to have a name other than the
namespace that can't be called poor design? Other than that, I don't personally
have any ideas on how that could be simplified.
I hope to respond to the other emails in this thread when I get the time to,
especially Timothy's. Hopefully that'll happen once I finish one project in
about a week or so.
Cheers,
Greg

Re: Lisp newbie seeks (macro?) wisdom - instrumentation and app metadata
Here is where I started... http://www.lisperati.com/clojure-spels/casting.html I personally disagree about being so timid with macros, however, I do not code Clojure with a team of other people =P. The one thing you will find about Clojure is that it slaps a limit on the types of macros you can do. This limit does not necessarily stop you from creating amazing things with macros but it is there. So of the macros that you will find in these LISP SPEL books will not be easily recreated in the hampered(pampered?) Clojure language. Clojure was meant to be a more corporate friendly, pragmatic language; thus, no reader macros. On Friday, August 9, 2013 6:21:02 PM UTC-4, Jace Bennett wrote: Thanks everyone. Good stuff.

Macros are more like code gen, so I'll think back to those techniques, and search for analogues and maybe even epiphanies. I think I had the ideas of dynamism and DRY complected (sorry, had to).

Re: apply inc
How many args does inc supports ? Only one. (apply inc [ 1 3 ]) is the same as (inc 1 3) which would also trigger an arity exception. apply does not call the given fn on each item in the collection it's given, it calls it once with the whole collection as the argument list. (map inc [1 3]) calls inc on every item in the vector and would return (2 4). Hope it's clear. Luc P. Hi there: Why does (apply str [2 3]) work and not (apply inc [4 5]) though (apply inc [4]) does work? Thanks. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Leiningen 2.3.0 and uberjar
I experienced this as well; when I opened the resulting jar, I found source files rather than class files. Not sure what causes this.

Re: apply inc
When you write (apply inc [4 5]) it's like (inc 4 5) But the inc function accepts only one argument. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

You could possibly batch import it all into MySQL, and let people SQL query over it.

Re: Interest in a commercial IDE for Clojure?
Instead of doing a plugin and instead of starting something from scratch like Nightcode, would it make more sense to take some of the open source components of Intellij and use that as a basis for a Clojure-based IDE? It seems to me that one of the biggest problems with IDEs like Eclipse and Intellij as compared to Emacs is that there's so much more work involved in writing a plugins as opposed to writing 20 lines of Elisp code. If you could leverage some of the components of Intellij as a basis for a Clojure based IDE/Texteditor then you don't have to start from scratch, but since you're just leveraging Intellij libraries instead of writing plugins, you can develop it as a Clojure framework/IDE instead of the other way around.
