Clojure 1.3 updated cheatsheet with links to clojuredocs.org
Thanks to several people who provided feedback, especially Steve Miner, and to Alex Miller for updating the web site yet again, there is a new cheatsheet at: http://clojure.org/cheatsheet There are many small and medium-sized changes from the version for Clojure 1.2 that was published until early February, 2012, but here are the main ones: + New today: most links on the page now go to the documentation on clojuredocs.org. These pages have not only the documentation that the old links had, but also one click to see the source code of the function, and very often user-contributed examples of using the function/macro/whatever-it-is. + Also new today: Added "Destructuring" subsection under "Special Forms", with a link to destructuring examples on clojure.org, followed by a list of macros where destructuring is most commonly used. + Renamed "Printing" section to "IO", and expanded its contents. Check it out. + Renamed "Multimethods" section to "Abstractions", and copied its content from Michael Fogus's corresponding section in his ClojureScript cheatsheet (thank you, Fogus). + Added new section "Metadata", with some hints on what all those ^:foo things mean. + Removed mention of structmaps (defrecord is recommended) + Moved Regex functions to strings section I'm not planning on any more updates soon, but if anyone has suggestions for further improvements, please contact me.

Re: clojure.test on ClojureScript?
Shantanu, I have been experimenting with this in ClojureScript One. The latest version is in the M003 branch. The example that Stuart links to is a complex integration test. Here is an example of some unit tests which test ClojureScript code. https://github.com/brentonashworth/one/blob/M003/test/one/test/dispatch.clj The idea is to keep writing tests in Clojure using clojure.test but add the ability to easily evaluate some forms in a JavaScript environment. This allows you to have one test suite for a Clojure/ ClojureScript project with integrated test results. The same technique could be used with other test frameworks. In the above example, you set up the test namespace in the same way you would with Clojure tests. You then have the `in-javascript` macro which sets up the ClojureScript namespace and allows you to define functions that you can call from ClojureScript in the tests below. All ClojureScript in the tests below will be evaluated in the namespace that you set up here. In your tests, when you want to evaluate something in the JavaScript environment, you wrap that form in the `js` macro. If you checkout this branch you can run tests in three ways: 1) `lein test` will run all the tests as it normally would. The current setup will launch a browser which can be used as the evaluation environment. 2) You can run tests from a Clojure REPL: (dev-server) (require 'one.test) (require 'clojure.test) (require 'one.test.dispatch) (def ee (one.test/browser-eval-env)) ;; go to the development or fresh page (binding [one.test/*eval-env* ee] (clojure.test/run-tests 'one.test.dispatch)) 3) If you are in a ClojureScript REPL, you can run the tests with: (run-tests 'one.test.dispatch) In each case you need to have a JavaScript environment in which to evaluation things. In case 1 this is created for you. In case 2 you have to manually set it up. In case 3 it uses the active ClojureScript REPL's environment. This is all very experimental. I hope it gives you some good ideas for where to start. Thanks, Brenton On Feb 25, 11:34 pm, Shantanu Kumar wrote: > Hi, > > Has anybody got clojure.test working with ClojureScript?

Re: "-function" special?
The leading dash is a convention in two places: - gen-class methods implemented by Clojure functions (e.g. -main) - low-level method implementations of built-in protocols in ClojureScript The dash has no special significance as far as the compiler is concerned, it's just part of the name. -Stuart Sierra clojure.com -- You received this message because you are subscribed to the Google Groups "Clojure" group.

[lazytest] Disable colored output
Hello, I'm using IntelliJ IDEA to develop my clojure programs and I'm using lazytest to test them. I'm also using maven and corresponding IDEA plugin to manage my projects. When I run lazytest:run goal using this plugin, the console window shows console output of 'mvn lazytest:run' command, but since this is regular text window it does not handle ANSI terminal codes, so I'm getting something like this: [32m.

Re: Major lein-cljsbuild update: 0.1.0
Yeah, I considered that, but then decided that the crossover path was similar to the "classes" dir, which is not a dotfile. Really in the end I just made an arbitrary decision. :) Fortunately, Leiningen 2 has a :target-path setting, which sets the path for all output files (classes, etc). Once Leiningen is officially released, I'm going to revisit a few things about lein- cljsbuild to make it more idiomatic, which will include using the :target-path for things like the crossover path.

Re: Bret Victor - Inventing on Principle
Actually, I guess this is the driving force behind my "activism" about "literate programming". What we do now is a "social wrong" in the sense that we are creating software that could be so much better, in an engineering sense, than we do now. We create software but we lose the most valuable part of the project by only crafting software that communicates with the machine. The real value is the communicating the ideas to other people. Once we "change the world" to expect programs to be literate everyone will have their expections raised to the point where they consider non-literate programs to be unprofessional.

Re: Google Summer of Code 2012 - any mentors?
So the application submiting procedure for organizations starts tomorrow but sadly there isn't any word about it at least on Confluence. There are willing mentors on the clojure-dev list and ideas to submit but as far as I understood from the GSOC site an organization must apply to host all these project ideas and subsequently assign mentors. Here's how a mentoring organization should apply (may save some time): http://www.google-melange.com/gsoc/document/show/gsoc_program/google/gsoc2012/faqs#mentoring_apply . Here's an example of the idea list for GSOC: http://community.kde.org/GSoC/2011/Ideas Hopefully we will see Clojure as a mentoring organization for the Clojure itself and third-party projects too.

new version 1.0.1 of let? macro
Version 1.0.1 of the let? macro adds the :is keyword. The let? macro is on github at https://github.com/egamble/let-else and on clojars at https://clojars.org/egamble/let-else. I've found let? very useful in replacing nested lets, when-lets, if- lets, whens, and ifs with a single let form. It allows exceptional cases to be handled with :when and :else clauses in the bindings, so they don't obscure the primary, unexceptional structure of the function. - Evan -- You received this message because you are subscribed to the Google Groups "Clojure" group.
