anaphoric macro?
Hi, I want to write a macro that introduces new variables from data. The data is a vector and looks like this for example: [a b c] I want to use the macro like this: (def-names [a b c] (str a b)) What code I want the macro to produce from the above is the following: (let [a a b b c c] (str a b)) Is it possible to do that?

Re: anaphoric macro?
Since the bindings are a function of the data that's passed in, IMO you don't need a anaphoric macro for this. For example - (defmacro def-names [names body] (let [bindings* (vec (mapcat (juxt symbol identity) names))] `(let ~bindings* ~@body))) As to whether it's a good idea or not, I'd say it depends but YMMV.

Il giorno martedì 23 luglio 2013 04:11:48 UTC+2, frye ha scritto: Hey all, *A)* Thanks for all the feedback on this topic. There's a few interesting things here. Notably that there are at least these existing blog engines: - http://github.com/bitemyapp/neubite (apparently needs a WYSIWYG editor) - https://github.com/yogthos/yuggoth (although this advertises itself as a full blog engine) *B)* I'll also look into putting HTML code within Markdown text. Wrt * Asciidoc*, what I wonder is i) does it handle all media types (images, video, audio, etc) and ii) are there well-developed web-editors for asciidoc ? i) Yes http://www.methods.co.nz/asciidoc/asciidoc.html#X98 :) ii) I haven't found none. However, it should be quite feasible to write AsciiDoc markup in plain text and render a preview in real time in-browser using asciidoctor.jshttp://asciidoctor.org/news/2013/05/21/asciidoctor-js-render-asciidoc-in-the-browser/. *C)* Also, the idea of a static site or blog generator (like Jekyll) is good. But that strikes me as a sub-set of a full-featured blog engine. My concept of having a small core (or kernel, if you like), would certainly allow for a static site generator as a plug-in. Looks like there are already working examples with: http://liquidz.github.io/misaki I would still like something.. a blog library that you can thread into your existing site. It wouldn't make too many assumptions about your setup (data store, http framework, templating, workflow, etc). And it would allow you to plug-in pieces on an as needed basis. I can't see that in neubite or yuggoth, unless I missed it. Please let me know. I agree.

Can we please deprecate the :use directive ?
I think I read somewhere that :use is no longer encouraged, but I could be mistaken. From what I've read, it seems like most people agree that Clojure has too many ways of including/importing/referencing/requiring/using things: http://blog.8thlight.com/colin-jones/2010/12/05/clojure-libs-and-namespaces-require-use-import-and-ns.html The above gives a very nice explanation of all the various difference, but it also acknowledges their complexity. Since :use uses :require, and since :require can do everything that :use can, can we simplify Clojure programming a bit for newcomers by deprecating the use of :use? The situation in ClojureScript is even worse because it adds :require-macros on top of all the other ways of including files. Ideally, it would be awesome if there was just a single directive for everything, but perhaps there's some complicated low-level reason why that's not possible. :-\ Thoughts? Thanks, Greg P.S.

Re: Can we please deprecate the :use directive ?
We have production code using it. It's easy to say that it's a bad pattern after the fact. We have been using it in a disciplined way. It simplifies our life in the REPL we have some tools we want to see included automatically each time we switch to a name space. Anything else aside from clojure.core is required using an alias. This minimized name clashes to zero so far. This is easily spottable in the ns macro declarations and is not a source of confusion for us. We have less manipulations to do in the REPL when attaching to the live app with these defaults included. I do not mind about the deprecation warning as a first step. However I would like some breathing space before it gets removed entirely. It's just another to do on top of the pile of work we have these times... Luc P.

Re: Can we please deprecate the :use directive ?
We only have :use in a couple of legacy tests and two scratch projects. We've switched from :use to :require .. :refer :all for situations where :use used to make sense (primarily in a test ns where we want to just refer in all of the ns being tested). We have a handful of places where we :refer :all elsewhere because the code reads better without ns aliases all over the place and we bring in a lot of functions. Certainly in blogs and documentation, :require .. :as short alias seems a better approach for teaching / explaining things but I'm sure I'm guilty of :use in earlier blog posts about Clojure (... checking ... yup, three blog posts from early 2012 contain :use, mostly with :only, so those should be updated to use :require / :refer instead).

Re: Can we please deprecate the :use directive ?
Yea, I have a single namespace with project-specific common utilities which I refer to as u/some-util-function. For me, it's a bit scary to have implicit symbols in scope. A typo can make a local binding refer to something that might not exist in production, or at least not what's intended. Conversely, I don't want extra code in my project that has nothing to do with the project. Seems useful to enforce a separation of the artifact from the tools that made it, more-so for a lib that other things depend on than a production app. The 'user' namespace can cover the use-case of convenience functions? Or, you can add those symbols dynamically at run-time when you need to with something like: https://github.com/flatland/useful/blob/develop/src/flatland/useful/ns.clj#L26 or some aggregated (require ..) calls.

What's problematic about it is that it's slightly easier to do the wrong thing. It seems insignificant, but 98% of times you use use, it's going to be wrong.

Re: Can we please deprecate the :use directive ?
None of what has been said so far makes me believe that our usage of use is bad. It's like a rope, you can use it for useful purposes or you can hang yourself. You use it at your own taste and will. Lack of discipline does not constitute for me a reason to trash a feature as scarce as his usefulness seems to be. :refer :all can be used as badly as :use. I am not convinced that removing a facade and leaving the feature available through a backdoor makes life better for anyone. :use is easily searchable and quite obvious. Not sure about spotting :refer :all in 15 name space require clauses. You will simply end up say do not use refer all instead of warning against using use. Gee, What a lot of uses in this thread :) Luc P.

Re: Can we please deprecate the :use directive ?
I think what we're proposing is not about removing the capability to do 'use'. That will remain, it's clojure after all. You could also implement it yourself easily enough. The issue is whether it's worthwhile to have it as a core function, without some kind of notice that better things exist. For instance, we have defrecords now, no one's going to reach for defstruct because records are documented and promoted more thoroughly. But 'use' is more pervasive, and also 'easier'. As the language grows, it'll be good for newcomers to have less things to think about, so deprecation is a way to counter bad inertia. The damage of 'use' is also less visible on the small scale, so that's why it's hard to make an argument about it. :require is proportionately more verbose for an effect. Use's verbosity is inversely proportional to its effect, so it takes extra effort to limit its effects. A limited scope by default is what I mean by 'good', for similar reasons that clojure goes with 'immutability by default'.

Re: Can we please deprecate the :use directive ?

Destructuring assignment complects assignment and getting values from a data structure (as the macroexpansion of (let [[a b] x]) demonstrates. Those examples provide an overall simplification for common constructs. As the 'use' docstring says, it is Like 'require, but also refers to each lib's namespace using clojure.core/refer. so it explicitly combines two already somewhat complex operations. When we added :refer to 'require' we also complected things but we improved expressiveness and we allowed the overall 'ns' construct to be more uniform and consistent so I think, on balance, that was a win (and I certainly like having one construct - :require - in my ns declarations rather than a mix of :use and :require). We probably should have taken that opportunity to deprecate :use at the same time but as I recall, :refer was added very late in the cycle and arguing over deprecating :use would have detracted from the discussion of the utility of adding :refer to :require in the first place. -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ World Singles, LLC. -- http://worldsingles.com/ Perfection is the enemy of the good. -- Gustave Flaubert, French realist novelist (1821-1880) -- -- You received this message because you are subscribed to the Google Groups Clojure group.

From what I've read, it seems like most people agree that Clojure has too many ways of including/importing/referencing/requiring/using things: http://blog.8thlight.com/colin-jones/2010/12/05/clojure-libs-and-namespaces-require-use-import-and-ns.html The above gives a very nice explanation of all the various difference, but it also acknowledges their complexity. Since :use uses :require, and since :require can do everything that :use can, can we simplify Clojure programming a bit for newcomers by deprecating the use of :use? The situation in ClojureScript is even worse because it adds :require-macros on top of all the other ways of including files. Ideally, it would be awesome if there was just a single directive for everything, but perhaps there's some complicated low-level reason why that's not possible. :-\ Thoughts? I find that use of `:use` makes code more difficult to read. Names from clojure.core are written without the namespace; everything else I expect to see a namespace in front to provide context.

Re: [ANN] verily, non-magic testing lib
Whoops. Looks like I didn't check the namespace well enough, there's already a lib called verily. (Sorry Justin.) Will think up a new name soon. On Tue, Jul 23, 2013 at 11:55 PM, Steven Degutis sbdegu...@gmail.comwrote: https://github.com/evanescence/verily Verily is a new testing lib with a few goals: - Build off existing Clojure concepts (functions, vars, etc) - Be as functional/immutable as possible - Be easy to use from terminal or REPL - Have composable pieces that are easy to swap out - Keep running tests separate from reporting the results Some upcoming features: - Some convenience functions for assertions - Better reports -Steven -- -- You received this message because you are subscribed to the Google Groups Clojure group.
