Re: [ANN] Grenada 1.0.0-rc.2
Hey Richard, Great work on the project! I'd love to see the final generated output if you have time to do so. Also, we at Helpshift are working on a similar project here - https://github.com/helpshift/hydrox. It'll be great to get your input to see how the two libraries compare, what each one potentially solves and whether there is synergy for solving the documentation problem. Chris.

It is now called Grenada https://github.com/clj-grenada/grenada-spec and can be described vaguely as a Clojure metadata build and distribution system. Features: - for library authors: assemble and publish (API) documentation packages similar to Javadoc JARs, but containing well-defined data instead of HTML. - for developers: provide structured information in addition to doc strings. Annotate Clojure objects that don't support doc strings with easily accessible documentation (to be implemented). - for documentation editors: jazz up the documentation of existing Clojure libraries; assemble documentation and examples from different sources. - for toolsmiths: build on a rigorously flexible model of metadata about things in the Clojure ecosystem (Taken from the project home page https://github.com/clj-grenada/grenada-spec.) Notable products of the project: - a data model https://github.com/clj-grenada/grenada-spec/blob/devel/SpecOverview.md (can be understood as a draft) - lib-grenada https://github.com/clj-grenada/lib-grenada, implementing the model and providing convenience - the concept of Datadoc JARs – like Javadoc JARs, but instead of HTML containing EDN files with documentation and arbitrary other data - a Leiningen plugin https://github.com/clj-grenada/lein-datadoc producing and deploying such JARs for your project Status: - Everything is usable, though not very convenient at times. If you've read the example of Dorothy the Documenter in the Clojure Gazette interview: what is described there works https://github.com/clj-grenada/lib-grenada/blob/devel/doc/tutorial.md . - The documentation is fairly extensive, though not well-organized. - The auxiliary library Jolly https://github.com/clj-grenada/jolly can be used to convert Grimoire http://conj.io data to Datadoc JARs https://clojars.org/org.clojars.rmoehn/clojure. - I would be happy if you use the Leiningen plugin to deploy Datadoc JARs for your libraries to Clojars. – Some day there might be an application which displays those data in a way similar to Autodoc or Codox. – The plugin has some issues, though, so don't get wound up. There's still plenty to do https://github.com/clj-grenada/grenada-spec/blob/devel/roadmap.md, but I'd be happy if you take a look.

It’s interesting for me to be able look at this in hindsight and really question the value of why I did this in a certain way.. As context, I didn’t start with the pattern and tried to fit things to it… I wrote a code bunch of code, refactored it a couple of times, and found commonalities in design that I was able to extract into what is now being discussed.

Re: a question about Chris Zheng's Abstract Container Pattern
The example in the article is probably the smallest example I can come up
with.
http://z.caudate.me/the-abstract-container-pattern
The code for the concrete implementations speaks for itself I think, it is
about 10 lines to hook in jetty and http-kit to the framework.
if we think about how much code an interface/abstract/concrete design
pattern can potentially reduce over a strict interface/concrete design
pattern in the java, then it's exactly the same with clojure.
One particular benefit of this particular pattern that I am exploiting is
the fact that you can then specify exactly what you want in the config. I'm
a big fan of making everything explicitly clear within the config itself so
if we have a system with some a component-style dependency injection model
(see http://docs.caudate.me/hara/hara-component.html), you can easily do
something like this to get a jetty server up:
{:server {:type :jetty
:port 8080}
and if you want a :http-kit server, you just change the config as such:
{:server {:type :http-kit
:port 8080}
I've done this quite a bit with mocking... for example, here -
https://github.com/MyPost/cassius/blob/master/src/cassius/component.clj
changing
{:db {:type :database}}
to
{:db {:type :mock}}
will work exactly the same way, irrespective of dependency injection
framework - in this case, I'm using the stuartsierra/component framework.

[ANN: cassius 0.1.14] - Cassandra as a Big Nested Map
I'm happy to announce that the team at MyPost (https://*digitalmailbox* .com.au/) has decided to release a library that we have been working on for the past couple of months. https://github.com/MyPost/cassius Apparently its `also only the second release of open source software by a public sector organisation in Australia` (http://www.andykelk.net/tech/open-sourcing-our-work-why-were-doing-it) Overview Cassius is a clojure wrapper around cassandra's thrift interface. It treats cassandra as a big mutable nested hashmap and provides the following abstractions: - cassandra data and schema can be represented as values and clojure maps. - keyspaces, column families, rows and columns can be abstracted as nested map layers - supercolumns are just one extra level of nesting The library has been used for both mocking and for higher level abstractions on top of cassandra. An ORM has been built and used internally at MyPost https://github.com/MyPost/cassius/blob/master/digitalmailbox.com.au to deal with legacy cassandra data. Motivation The library was motivated by an inability to reason about what changes the existing monolithic system was doing to the underlying database. In order to move away from the existing system into more agile architecture, the team had to be careful about reworking features without breaking functionality. The typical work of code migration would end up looking something like this: 1. Get the current state of the DB 2. Run some legacy code (java) 3. See what has changed in the DB 4. Rewrite that change in clojure cassius was designed as a tool for developers to reason about and test changes to cassandra. It also has the following features: - Written in thrift in order to support supercolumns in the legacy system. - Abstracts the database in such a way that tests are easy to write and easy to read. - Uses of conditional restarts for more control of error states. - Option to use the component/Lifecycle framework. Mock DB is included for testing purposes. - Uses the Hashmap as a protocol, defined in cassius.protocols/IMap. - Methods: put-in, peek-in, keys-in, drop-in, set-in, select-in and mutate-in https://github.com/MyPost/cassius#usage The repo is here: https://github.com/MyPost/cassius Please have a play! -- You received this message because you are subscribed to the Google Groups Clojure group.

A library for hacking and exploring the jvm:
Whats New https://github.com/zcaudate/iroh#0190.1.9
- . macro now supports both .accessors and :accessor calls
- delegate added for better object support
https://github.com/zcaudate/iroh#0160.1.6
Changed syntax:
- .$ to . (threading macro)
- . to .% (display class hierachy)
- Added .% (display class info)
- Now .?, .% and .% works both on classes and instances
https://github.com/zcaudate/iroh#installationInstallation
Add to project.clj dependencies:
[im.chit/iroh 0.1.9]
For working in the repl or emacs, inject the core functionality into your
clojure.core namespace using vinyasa https://github.com/zcaudate/vinyasa by
adding the following to your ~/.lein/profiles.clj file:
{:user {:dependencies [[im.chit/iroh 0.1.8]
[im.chit/vinyasa 0.2.0]]
:injections [(require 'vinyasa.inject)
(vinyasa.inject/inject 'clojure.core
'[[iroh.core delegate ns var . .? .* .% .%]])
]}}
--
delegate - Transparent Bean
Delegate does what bean does but it actually allows field access to the
underlying object. This way, one can set and get values from the object :
(def a hello)a ;;= hello
(def a (delegate a))a ;;= java.lang.String@99162322 {:hash 99162322,
:hash32 0, :value #char[] [C@202cf33f}
@a ;;= {:hash 99162322, :hash32 0, :value #char[]
[C@202cf33f}(keys a);;= (:value :hash :hash32)(a :hash) ;;=
99162322(:hash32 a) ;;= 0 (a :value (char-array world)) ;;= world
a ;;= world (But I thought string where immutable!)
. - Threading
A shorthand way of accessing private field is done by using .:
(def a hello)(. a :value) ;= #char[] [C@753f827a(. a (:value (char-array
world)))a ;;= world

[ANN] - lein-repack 0.1.0 - Repack your project for deployment and distribution
lein-repack Repack your project for deployment and distribution https://github.com/zcaudate/lein-repack#motivationMotivation lein-repack was written to solve a problem I had with utilities and general purpose libraries. In my experience, clojure libraries are much better when they are distributed in small packages. However, functionality is much easier to develop when the project is big: when we try to build our general purpose libaries in small packages, they become a nightmare to test and deploy. lein-repack redistributes your code base into managable, deployable chunks and analyses your source files to automatically resolve internal and external dependencies. It this way, a big clojure project can now be broken up into sub-packages for deployment and redistribution. The plugin will: - Create sub-projects for all sub-namespaces in a project - Will look through source files and figure out project dependencies - Will repackage a project into many smaller artifacts for easier deployment and distribution -- Walkthrough For example, if there were a project called lama at version 0.1.0 and the files were organised like this: - src - lama - weapons - gun.clj - food - prepare.clj - food.clj - core.clj Running lein repack install will split the project into four jars and install them in maven. lama-0.1.0.jar lama-core-0.1.0.jar lama-food-0.1.0.jar lama-weapons-0.1.0.jar Running lein repack deploy will deploy all four artifacts to clojars. Once the artifacts are installed/deployed, they are now ready to be used.

Strange behaviour for proxy when two abstract classes are passed in
I know this is a silly example but I am curious to know what is happening with the proxy method. I have set up two calls to proxy: 1. (def cp (proxy [java.util.AbstractMap clojure.asm.ClassVisitor] [])) 2. (def cp (proxy [clojure.asm.ClassVisitor java.util.AbstractMap] [])) The first call is fine and it return cp.

ANN: [vinyasa 0.1.5] - dynamic reloading of java code without repl restart
I've added a new functionality for vinyasa 0.1.5 - a much needed function
for reloading java code
the repo is here: https://github.com/zcaudate/vinyasa
Enjoy!
---
reimport
Don't you wish that you could make some changes to your java files and have
them instantly loaded into your repl without restarting? Well now you can!
For example, in project.clj, you have specified your :java-source-paths
(defproject .
:source-paths [src/clojure]
:java-source-paths [src/java]
)
and you have a file src/java/testing/Dog.java
package testing;public class Dog{
public int legs = 3;
public Dog(){};}
You can load it into your library dynamically using reimport
(reimport '[testing.Dog]);;= 'testing.Dog' imported from
project/target/reload/testing/Dog.class
(.legs (Dog.));; = 3
You can then change legs in testing.Dog from 3 to 4, save and go back to
your repl:
(reimport '[[testing Dog]]) ;; supports multiple classes;;= 'testing.Dog'
imported from project/target/reload/testing/Dog.class
(.legs (Dog.));; = 4
If you have more files, ie. copy your Dog.java file to Cat.java and do a
global replace:
(reimport) ;; will load all classes into your namespace;;= 'testing.Dog'
imported from project/target/reload/testing/Dog.class;; 'testing.Cat'
imported from project/target/reload/testing/Cat.class
(.legs (Cat.));; = 4
Now the pain associated with mixed clojure/java development is gone!

inject allows easy customisation of your clojure.core namespace by allowing
injecting of the functions that you have always wanted to have in your
profiles.clj file. Here is an example taken from myprofiles.clj.
{:user {:plugins [...]

[org.clojure/tools.namespace 0.2.4]
[io.aviso/pretty 0.1.8]

:injections [(require 'spyscope.core)
(require 'vinyasa.inject)
(vinyasa.inject/inject 'clojure.core

[vinyasa.pull pull]
[vinyasa.lein lein]

ANN - [vinyasa 0.1.0] - Give your clojure workflow more flow
I've been rethinking my clojure workflow and came up with this little
library, allowing sweet customisations of the clojure.core namespace for
development purposes:
https://github.com/zcaudate/vinyasa
It has three functions - pull, lein, inject - and their uses are described
below.
Chris.
-
vinyasa
Give your clojure workflow more flow.
https://github.com/zcaudate/vinyasa#installationInstallation
Add vinyasa to your profile.clj:
{:user {:plugins [...]
:dependencies [
[im.chit/vinyasa 0.1.0]
]
}
:injections [...
(require '[vinyasa.inject :as inj])
(inj/inject 'clojure.core
'[[vinyasa.inject inject]
[vinyasa.pull pull]
[vinyasa.lein lein]])
...]
}
https://github.com/zcaudate/vinyasa#usageUsage:
If you are in emacs and are in a clojure project, you can run nrepl-jack-in and
use the added functionality straight away. If you are running lein repl and
are in the user namespace, reload the user namespace before using:
(ns user) (lein) (pull hiccup)
https://github.com/zcaudate/vinyasa#pullpull
How many times have you forgotten a library dependency for project.clj and
then had to restart your nrepl?pull is a convienient wrapper around the
pomegranate library:
(require 'hiccup.core);; = java.io.FileNotFoundException: Could not locate
hiccup/core__init.class or hiccup/core.clj on classpath:
(require 'hiccup.core) (pull 'hiccup);; = {[org.clojure/clojure 1.2.1]
nil, ;; [hiccup 1.0.4] #{[org.clojure/clojure 1.2.1]}}
(use 'hiccup.core) (html [:p hello World]);; = phello World/p
(pull 'hiccup 1.0.1);; = {[org.clojure/clojure 1.2.1] nil, ;;
[hiccup 1.0.1] #{[org.clojure/clojure 1.2.1]}}
https://github.com/zcaudate/vinyasa#leinlein
Don't you wish that you had the power of leiningen within the repl itself?
lein is that entry point. You don't have to open up another terminal window
anymore, You can now run your commands in the repl!
(lein);; Leiningen is a tool for working with Clojure projects. Several
tasks are available:;; check Check syntax and warn on
reflection.;; classpath Write the classpath of the current project
to output-file.;; clean Remove all files from paths in
project's clean-targets.;; cljsbuild Compile ClojureScript source
into a JavaScript file. .;; .
(lein javac) ;; Compile java classes
(lein install) ;; Install to local maven repo
(lein uberjar) ;; Create a jar-file
(lein push);; Deploy on clojars I still use lein-clojars
https://github.com/zcaudate/vinyasa#injectinject
I find that when I am debugging, there are additional functionality that is
needed which is not included in clojure.core. The most commonly used
function is pprint and it is much better if the function came with me when
I was debugging.
The best place to put all of these functions in in the clojure.core
namespace inject is used to add additional functionality to namespaces so
that the functions are there right when I need them. Inject also works with
macros and functions (unlike intern which only works with functions):
(inject 'clojure.core '[[clojure.repl dir]]);; = will intern
#'clojure.repl/dir to #'clojure.core/dir
(clojure.core/dir clojure.core);; *;; *';; *1;; *2;; *3;; *agent*;;
*allow-unresolved-vars*;; *assert* ...;; ...
inject can also work with multiple entries:
(inject 'clojure.core '[[clojure.repl doc source]]);; = will create the var
#'clojure.core/doc and #'clojure.core/source
inject can also take a prefix:
(inject 'clojure.core ' '[[clojure.repl doc source]]);; = will create the
var #'clojure.core/doc and #'clojure.core/source
inject can use vector bindings to directly specify the name
(inject 'clojure.core ' '[[clojure.repl doc [source source]]]);; = will
create the var #'clojure.core/doc and #'clojure.core/source

inject allows easy customisation of your clojure.core namespace by allowing

[ANN] purnam 0.1.8 - native javascript essentials for clojurescript (documentation out!!!)
I'm really happy that I have finish documenting my new-ish clojurescript library. You can find it here: http://docs.caudate.me/purnam/ - purnam is a *clojurescript* library designed to provide better clojurescript/javascript interop, testing and documentation tools to the programmer. It also has very comprehensive modules for angular.jshttp://angularjs.org/ applications. Current projects requiring interface with external javascript libraries will greatly benefit from this library. 'Pure' clojure/clojurescript libraries will also benefit with its unit-testing and documentation workflows. The library was written to solve a number of pain points that I have experienced in clojurescript development: Better JS Interop The first pain point was having to deal with the clojurish (.dot syntax) for javascript interop as well as a lack of functionality when working with native js objects. This made it especially hard for working with any external js library. Purnam offers: - purnam.cljs http://docs.caudate.me/purnam/#purnam-cljs - functions for native objects and arrays - purnam.js http://docs.caudate.me/purnam/#purnam-js - a set of macros allowing javascript-like syntax for better interop - purnam.types http://docs.caudate.me/purnam/#purnam-types - clojure protocols for native objects and arrays In-Browser Testing The second pain point was the lack of testing tools that worked within the browser. Even though testing withphantom.js http://phantomjs.com/ was fine for non-browser code, I wanted something with more debugging power and so unit testing is integrated with the karmahttp://karma-runner.github.io/ test runner using two different test styles: - purnam.test http://docs.caudate.me/purnam/#purnam-test - testing using jasmine http://pivotal.github.io/jasmine/ syntax - purnam.test.sweet http://docs.caudate.me/purnam/#purnam-test-sweet - testing using midje https://github.com/marick/Midje syntax (compatible with midje-doc https://www.github.com/zcaudate/lein-midje-doc) Angularjs on Clojurescript The third pain point was the code bloat I was experiencing when developing and testing *angular.js* code using javascript. It was very easy to complect modules within large *angular.js*applications and I wanted to use clojure syntax so that my code was smaller, more readable and easier to handle. Purnam offers: - purnam.angular http://docs.caudate.me/purnam/#purnam-angular - a simple dsl for eliminating boilerplate*angular.js* - purnam.test.angularhttp://docs.caudate.me/purnam/#purnam-test-angular - testing macros for eliminating more boilerplate test code for services, controllers, directives and filters Integrated Documentation The fourth pain point was the lack of documentation tools for clojurescript as well as clojure. purnam is compatible withmidje-dochttps://www.github.com/zcaudate/lein-midje-doc so that the integrated testing and documentationworkflowhttp://z.caudate.me/combining-tests-and-documentation/ can be also used in clojurescript. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Testing with Angular.js, Clojurescript and Purnam - Code and Part 1
Code: https://github.com/zcaudate/purnam-angular-example Demo: http://docs.caudate.me/purnam-angular-example/ Article: http://z.caudate.me/purnam-angular-js-testing-part-1-services/ Even with the karma http://karma-runner.github.io/ test runner, testing in angularjs is painful. It's one thing to be able to write a *angular.js*controller, its another to be able to test them. Making it more difficult is the sheer complexity of the framework. There are different strategies of testing controllers, directives, filters and injectables (values, services, factories and providers) There are two excellent articles about testing in angular.js by Year of Moo. Herehttp://www.yearofmoo.com/2013/09/advanced-testing-and-debugging-in-angularjs.html and Herehttp://www.yearofmoo.com/2013/01/full-spectrum-testing-with-angularjs-and-karma.html. However, my eyes start hurting when I look at the test code. It is modular, it is brilliantly thought out, it is *very* complete... but it is seriously hard to get my head around. An example of controller testing can be found herehttps://github.com/yearofmoo-articles/AngularJS-Testing-Article/blob/master/test/unit/controllers/controllersSpec.js It took me about a couple of days to summon up the courage to even attempt to read the code. Then I realised that the tests weren't doing that much at all. Most of it was boilerplate and not that interesting. Out of about 5 lines of test code, something interesting only happened in one of them. I abstracted out all the angular.js testing code into macroshttps://github.com/zcaudate/purnam/wiki/Api---purnam-test-angular . The point I've been making on previous posthttp://z.caudate.me/if-you-cant-beat-them/ is that clojurescript rocks if we really embrace javascript libraries through macros. With macros for *angular.js*, working with angular.js is so much clearer than in javascript. I have put together an example projecthttps://github.com/zcaudate/purnam-angular-example that shows how one may go about doing a simple app with tests. I'm going to take a couple of posts to explain how purnam.angular, purnam.test and purnam.test.angular work together. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Testing Clojurescript Code with the Karma Test Runner
I thought this may also be of interest to those that are not subscribed to planet clojure.. From http://z.caudate.me/testing-clojurescript-code-with-karma/ The karma http://karma-runner.github.io/0.10/index.html test runner is an amazingly fully featured testing platform. Its lead developer Vojta Jina, is an integral part of google's the angular.js http://www.angularjs.org/ team and it is the default test runner for*angular.js* projects. Karma also works without *angular.js* and can also be used as a standalone tool for testing code on multiple browsers. purnam https://github.com/zcaudate/purnam includes *clojurescript* testing using jasmine http://pivotal.github.io/jasmine/ and karmahttp://karma-runner.github.io/0.10/index.html.

How to go about 'proving' why dynamically typed languages are better.
I'm a little bit miffed over this current craze of `types` and `correctness` of programs. It smells to me of the whole `object` craze of the last two decades. I agree that types (like objects) have their uses, especially in very well defined problems, but they have got me in trouble over and over again when I am working in an area where the goal is unclear and requirements are constantly changing. BTW... This is no means a criticism of all the type system work that is going on in the clojure community. I am a huge fan of Ambrose's Typed Clojure project because it gives me the *option *of using types... not shoving it down my throat. I like the freedom to choose. My experience of programming in clojure has freed me from thinking about types and hierarchies and this article rings so true: http://steve.yegge.googlepages.com/is-weak-typing-strong-enough. However, everywhere I look, there are smug type-weenies telling me that my dynamically typed program is bad because it cannot be `proven correct` and not `checked by the compiler`. This question on SO really makes me angry http://stackoverflow.com/questions/42934/what-do-people-find-so-appealing-about-dynamic-languages because no one is defending dynamic languages on there. The reason is very simple. because we don`t have a theory to back us up! I do want to put up an counter argument against this barrage of abuse against dynamic languages. And I want to put some academic weight behind this. The only counter I could come up with was to use Godel's incompleteness theorem. For those that don't know... here is an introduction to the man and his theory. http://www.youtube.com/watch?v=i2KP1vWkQ6Y. Godel's theorem, invalidated Principia Mathematica as a complete system of description. Principia Mathematica btw effectively led to Type Theory. According to http://en.wikipedia.org/wiki/Type_theory. The types of type theory were invented by Bertrand Russell in response to his discovery that Gottlob Frege's version of naive set theory was afflicted with Russell's paradox. This theory of types features prominently in Whitehead and Russell's Principia Mathematica. It avoids Russell's paradox by first creating a hierarchy of types, then assigning each mathematical (and possibly other) entity to a type. Objects of a given type are built exclusively from objects of preceding types (those lower in the hierarchy), thus preventing loops. I'm hoping to collect a few more `proofs` from the clojure community... for example... if there is a paper on why are type systems so bad at classifying animals... then please forward it on. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Hi All,
I've updated the library from 0.1.5 version with new features:
- handlers now can branch depending on exception data
(on :error [data]
(if ( data 5)
(escalate :too-big)
(continue data)))
- a additional `fail` handler for short-circuiting default behaviour
- a
strategieshttps://github.com/zcaudate/ribol/blob/master/test/ribol/test_ribol_strategies.clj
document that show different ways of controlling program flow beyond
try/catch

I'd love for some feedback.

ribol
ribol is a conditional restart library for clojure inspired by errorkit,
having a more readable syntax, and designed with the base
clojure.lang.ExceptionInfo type in mind.
https://github.com/zcaudate/ribol#installationInstallation:
In project.clj, add to dependencies:
[im.chit/ribol 0.2.1]
https://github.com/zcaudate/ribol#introductionIntroduction
ribol provides a conditional restart system. It can also be thought of as
an issue resolution system ortry++/catch++. The library provides an
alternative channel for resolving 'issues' (we use 'issues' here to
differentiate from 'exceptions', although they are pretty much the same
thing). It models a management structure, in which issues are reported to
management, who then what course of action to take depending upon the issue
and their own level of expertise:
-
When circumstances arise that need the attention of higher level
processes, an 'issue' would be raised that can be managed by any higher
level process.
-
An issue must have data as well as additional information attached:
- options that can be taken to resolve the issue
- a default option if there is no management intervention.
-
Issues are managed through handlers that check for the nature of the
issue and come up with the proper resolution process. There are six ways
that a manager can deal with a raised issue:
- directly (same as try/catch)
- using continue to keep going with a specified value
- using choose to specify an option
- using escalate to notify higher level managers
- using default to allow the issue to resolve itself
- using fail to throw an exception
Using these six different different issue resolution commands, a programmer
has the richness of language beyond the simple 'try/catch' statement at
his/her command to be able to craft very complex process control flow
strategies without mixing logic handling code in the middle tier. It can
also create new ways of thinking about the problem beyond the standard
throw/catch mechanism and offer more elegant ways to build programs.
Apart from the tutorial, interested users can peruse the
strategieshttps://github.com/zcaudate/ribol/blob/master/test/ribol/test_ribol_strategies.clj
document
(still a work in progress) to go through common restart strategies.
https://github.com/zcaudate/ribol#other-librariesOther Libraries
There are three other conditional restart libraries for clojure -
errorkithttps://github.com/richhickey/clojure-contrib/blob/master/src/main/clojure/clojure/contrib/error_kit.clj
, swell https://github.com/hugoduncan/swell and
conditionshttps://github.com/bwo/conditions
-
errorkit provided the guiding architecture for ribol. However, ribol
updates errorkit with more options for controlling exceptions, uses
ex-info which is part of core and has an updated and more understandable
syntax.
-
swell and conditions are written to work with
slingshothttps://github.com/scgilardi/slingshot
and try+/catch+.
https://github.com/zcaudate/ribol#novel-featuresNovel Features
- In addition to the other conditional restart Libraries, ribol offers
three more ways of handling error:escalate, fail and default. As of
version 0.2 of ribol, handlers are now much more flexible. As far as I
can tell, it is the only library that allows this type of resolution
switching (having an 'if' form in the 'on' handler to switch between
escalate and continue depending on the value of data:
(manage (manage
(mapv (fn [n]
(raise [:error {:data n}]))
[1 2 3 4 5 6 7 8])
(on :error [data]
(if ( data 5)
(escalate :too-big)
(continue data
(on :too-big [data]
(continue (- data
[1 2 3 4 5 -6 -7 -8])
- Additionally, the follow macros raise-on, raise-on-all and anticipate
offer
ways to hook into the java exceptions. Its use can be seen here: integer
division https://github.com/zcaudate/ribol/wiki/Robust-Integer-Divide

However, ribol updates errorkit with more options for controlling exceptions, uses ex-info which is part of core and has an updated and more understandable syntax. - swell was written specifically to work with the slingshot try+/catch+ packages and I thought that the two together carried too much baggage. ribol has no such dependencies. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

ANN - adi 0.1.5 (user friendly syntax for datomic)
I've pushed out a significant update for adi, along with quite a long
readme @ https://github.com/zcaudate/adi
Some highlights:
1. Required keys
(adi/insert! ds {:account {:credits 10}});; = (throws Exception The following
keys are required: #{:account/user :account/password})
2. Schema checking
(adi/insert! ds {:account {:user adi :password hello1 :type :vip}});;=
(throws Exception (:type :vip) not in schema definition)
3. Restrictions
(adi/insert! ds {:account {:user adi :password hello}});;= (throws
Exception The value hello does not meet the restriction: password needs an
integer to be in the string)
4. Search constraints
(adi/select ds {:account/credits '( 10)} :first :hide-ids);;= {:account
{:user adi3, :password hello3, :credits 1000, :type :account.type/free}}
5. Data views
(adi/select ds {:account/user adi1} :first :hide-ids :view {:account/books
:follow});;= {:account {:user adi1, :password hello1, :credits 0,;;
:books #{{:author Louis Cha, :name The Book and the Sword}}, :type
:account.type/free}}
(adi/select ds {:account/user adi1} :first :hide-ids :view {:account/books
:follow
:account/user
:hide
:account/password
:hide
:account/credits
:hide
:account/type

[ANN] - adi 0.1.1 - a `document` database grafted onto Datomic
I'm extremely happy to announce to the clojure community what I have been working on for the past couple of months. I'm calling it `adi`, sanskrit for `beginning`, acronym - (A) (D)atomic (I)nterface. Get it here: https://github.com/zcaudate/adi For the more technical minded, these are features of adi: - The Scheme Map and Datomic Schema Emission - Key Directory Paths as Map Accessors - The Datastore - Data Representation and Datomic Data Emission - Query Representation and Datomic Query Emission - Data Views as Faux `Documents` For the more airy-fairy, here is the heart-warming version: adi adi, rhyming with 'hardy' stands for the acronym (a) (d)atomic (i)nterface. The concept is simple. adi is a Document Database onto grafted on Datomic. It makes use of a map/object notation to interface with a Logical Query Engine. Datomic began something brand new for data, and adi leverages that incredible flexiblility with a syntax that is simple to understand. It converts flat, record-like arrays to tree-like objects and back again so that the user can interface with datomic the way datomic was designed to do. The key to understanding adi lies in understanding the power of a schema. The schema dictates what you can do with the data. Instead of limiting the programmer, the schema should exhance him/her. Using adi once a schema for an application has been defined, the data can be inserted in any shape, as long as it follows the coventions specified within that schema. Fundamentally, there should be no difference in the data-structure between what the programmer asks for and what the programmer is getting. We shouldn't have to play around turning objects into records, objects into logic queries... etc... Well... Not anymore... -- -- You received this message because you are subscribed to the Google Groups Clojure group.

[ANN] - purnam 0.0.9 (javascript.dot.notation language extensions for cljs)
This is a quick and dirty release for interested parties. I found it very
useful when working with angularjs. The syntax should not change that much
but there will be more documentation in the future. I would love to have
some input into additional features that could be added.
Excerpt from Github: https://github.com/zcaudate/purnam
Installation
In your project file, add
[purnam 0.0.9]
Why?
Because the javascript dot-notation is awesome and the
javascript/clojurescript interop (aget aset, .fn and .-propaccessors)
make for really ugly code. Using the language-extension macros,
clojurescript becomes more than twice as concise when working with existing
javascript libraries (I'm mainly working with angularjs).
So the use case can be seen below:
https://github.com/zcaudate/purnam#gettersGetters:
## javascript (12 keystrokes):
object.a.b.c
## clojurescript (45 keystrokes):
(- object
(aget a)
(aget b)
(aget c))
## clojurescript + purnam (16 keystrokes):
(? object.a.b.c)
https://github.com/zcaudate/purnam#settersSetters:
## javascript (17 keystrokes):
object.a.b.c = 10
## clojurescript (48 keystrokes):
(- object
(aget a)
(aget b)
(aset c 10))
## clojurescript + purnam (19 keystrokes):
(! object.a.b.c 10)
https://github.com/zcaudate/purnam#functionsFunctions:
These are really bad examples of code but its what usually happens when
working with existing javascript libraries. Using the dot-notation can save
alot of screen and head space:
## javascript (~100 chars):
var bad_code = function(obj, val){
obj.inner.number = 10;
val.inner.count = obj.inner.count + 10;}
## clojurescript (~180 chars):
(defn bad-code [obj val]
(- obj (aget inner) (aset number 10))
(- val
(aget inner)
(aset count
(+ 10 (- obj (aget inner) (aget count)
nil)
## clojurescript + purnam (~110 chars):
(def.n bad-code [obj val]
(! obj.inner.number 10)
(! val.inner.count
(+ 10 obj.inner.count))
nil)

Re: [ANN] - purnam 0.0.9 (javascript.dot.notation language extensions for cljs)
Well... This is strictly for working with js objects. The syntax is a wrapper around the functions 'aget-in' and 'aset-in' which I wrote. I just assumed that get-in doesn't work because you have to use aget for js objects... so they were an attempt to mimic that with js-objects. The .. Operator does make it much more concise but it's still ugly :) The purnam.js syntax also supports dot notation function calls... which is more than what getters and setters do. You can see examples of this on my GitHub: Eg def.n set-static-breadcrumbs [app v] (js/console.log Setting breadcrumbs) (! app.layout.breadcrumbs (let [arr (array)] (doseq [i v.trail] (arr.push app.static.|i|)) (arr.push v) arr))) -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] - purnam 0.0.9 (javascript.dot.notation language extensions for cljs)
Thanks Michael. I really didn't know how to 'sell' it because there's quite a bit of thought in there about how to make it work with existing javascript libraries so that the clojure syntax does not get in the way and it's difficult Maybe I have started talking def.n or about TDD first. I posted on the clojurescript group about that but the post it hasn't been moderated yet. @David: i never knew that you can add more parameters to aget. However, the only problem i found with using aget was that if I have a nested object and one of the keys are missing, then I get an undefined error. Where as I want it to fail with a nil. I'm not really that interested in promoting my ! and ? operators and comparing forms, but how entire libraries of code can be written. There's a code transformer macro that take an entire form and rewrites all of the dotted symbols. So that could be changed to take advantage of the efficient inlining. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] - purnam 0.0.9 (javascript.dot.notation language extensions for cljs)
Additional features are listed. Also, I`ve discovered a really easy way of automating TDD using karma, which quickens the compilation/testing dramatically and the jasmin macros where built for that: functions When f.n and def.n are used for function definitions, there is no need to write ?, ? and ! within the form as it is handled automatically. Actually, the short hand is avaliable Within any of the macro forms. Typing: - a.b.c is the same as typing (? a.b.c): - (inc a.b.c 1) is the same as typing (? inc a.b.c 1): - (a.call arg1 arg2) is the same as typing (! a.call arg1 arg2): - Only the setter function (! a.b.c (new value)) remains the same. Example: (def.n set-static-breadcrumbs [app v] (js/console.log Setting breadcrumbs) (! app.layout.breadcrumbs (let [arr (array)] (doseq [i v.trail] ;; Dot notation (arr.push app.static.|i|)) ;; Note the javascript-ish accessor (arr.push v) ;; Dot function call arr))) https://github.com/zcaudate/purnam#other-librariesOther Librarieshttps://github.com/zcaudate/purnam#angularjs angularjs Angularjs macros help alleviate the amount of callback functions that one has to write (def.module app [ui ui.bootstrap ui.compat]) (def.config app [$locationProvider] (doto $locationProvider (.hashPrefix !))) (def.config app [$routeProvider] (doto $routeProvider (.when (obj :redirectTo /home (def.controller app.MainCtrl [$scope $state App AppFn] (! $scope.app App) (! $scope.fn AppFn) (! $scope.state $state) ($state.transitionTo home)) jasmin Jasmin macros for clearer tests.

I had a vague description for purnam 0.0.9: https://groups.google.com/forum/?fromgroups=#!topic/clojure/AgZ_wVtdUFI Its the same code with a different read me...

Clojurescript Language Extensions (which the previous two are built upon) Why not use lispyscript/coffeescript/clang? I like each of the languages for their own features: - coffeescript for its succinctness - lispyscript for its syntax and macros - clang for its sheer brilliance and audacity However, in using each language I did find some weaknesses - coffeescript and its ambiguous syntax that changes meaning with whitespace - lispyscript is too new for me and not widely adopted - clang is to ambitious in what it is trying to do (make angular work with clojure) and I think there are definite performance implications in doing so. The goal of this project is to provide opt-in language extensions for clojurescript to have the same sort of succintness when working with angular and all other javascript libraries. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

I've updated the read me with more `practical` examples at the top and made another announcement =) But regarding the language extensions: @David. These are a set of optional extensions. But having said that, I really do hope that that you put `def.n` macro and `obj` into the main clojurescript library itself (and maybe somehow merge `!` with `set!`). It does compliment the existing cljs functions, work will with namespaces, and will be great for getting javascript/clojurescript guys onboard! -- -- You received this message because you are subscribed to the Google Groups Clojure group.

ANN: cronj - task scheduling
cronj This is another cron-inspired task-scheduling library. I have found many scheduling libraries for clojure: - quartzite - cron4j - clj-cronlike - at-at - monotony The first three all follow the cron convention. The task (also called a job) can only be scheduled at whole minute intervals. at-at has milli-second resolution, but was limited in the number of threads that have to be predetermined. It was good for looking after tasks that did not overlap between calls but not for tasks that may take an arbitarily long time. monotony uses core.logic, which is something that I am yet to understand. cronj is little different due to design requirements in the project that I am working on: - starts scheduled tasks at a per-second interval having high system- time accuracy without wasting system resourcs. - would spawn as many threads as needed, so that tasks started at earlier intervals could exist along side tasks started at later intervals. - an additional design requirement required that task handlers are passed a date-time object, so that the handler itself is aware of the time when it was initiated. it can be found at: https://github.com/zcaudate/cronj -- You received this message because you are subscribed to the Google Groups Clojure group.

how do we go about promoting new clojure libraries?
is there some sort of categorised list/wiki that we can add to for new libraries? -- You received this message because you are subscribed to the Google Groups Clojure group.
