Been away a while
Hi Everyone, I've been out of the Clojure scene for about 18 months due to an ill-advised detour into management. Don't worry! I've recovered pretty well but I was wondering if anyone can suggest what I should be looking at to bring me back up to speed. My current context is that I have a mediums sized rails monolith (~27,000 LOC excluding tests) that I want to gradually break up into an event sourced/CQRS architecture. I'm evaluating different approaches to writing my read and write services and I'm happy to rewrite some code. Spec looks like a very exciting way to define services. Maybe there are some good libraries that might help. Thanks very much Adrian -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Streaming a large file onto a channel
Hi Erick Thanks for getting back to me. On my system, I wasn't seeing the contents of my file being listed in the REPL.

Re: Streaming a large file onto a channel
Hi Adam I'm using the latest version on cider + cider-nrepl but it's a possibility. I suspect it's more of a case that I tried so many different combinations I polluted my repl beyond repair.

[JOB] Senior Mid Level Clojure roles in Glasgow
Hi All, Arnold Clark are looking for Clojure Developers and Senior Clojure developers to join the web development team at our offices in Glasgow City Centre. We're kicking off some projects in the new year and we are looking for some strong developers to form the backbone of the Clojure team to deliver projects alongside our existing Ruby/Rails and Front End Developers in a good Agile environment. These are green-field projects so you'll have a major input into the architecture of the systems and the day-to-day working practices we adopt. We realise that there are not a lot of experienced Clojure around so we have created a Senior role for people who really know the language and a mid-level role for people who have some experience but want to make it a full-time job. Hopefully that makes sense but let me know if you have any questions. I'll also be in London at Clojure Exchange next week if you are around and would like to talk in person. Many Thanks Adrian Here are the details of the 2 roles. Senior Clojure Developer: http://www.arnoldclark.com/careers/jobs/R5_010 Must haves: • Fluent working in Clojure (open source contributes and significant hobby projects are acceptable) • Industrial experience with Java • Senior Developer/Technical Lead experience in an Enterprise setting • Excellent grasp of Functional Programming • Agile development, especially Test Driven Development • Working on Unix/Linux environments Nice-to-haves: • Semantic Web • Datomic and/or other graph databases • Android Development • Exposure to Ruby on Rails • Experience working with UX designers and Front End Developers • MySQL or other database experience • A good computer science degree • Working on a Mac Clojure Developer: http://www.arnoldclark.com/careers/jobs/R5_011 Must haves: • Working knowledge of Clojure • Strong development experience • Experience in an Enterprise setting • Good grasp of Functional Programming • Agile development, especially Test Driven Development • Working on Unix/Linux environments Nice-to-haves: • Industrial experience with Java • Semantic Web • Datomic and/or other graph databases • Android Development • Exposure to Ruby on Rails • Experience working with UX designers and Front End Developers • MySQL or other database experience • A good computer science degree • Working on a Mac -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Acceptance testing with Clojure
Thanks for pointing out prism - it's just what I needed. Is there any way to add colours to the output so I can easily see if a test failed? On Sunday, 28 September 2014 15:34:39 UTC+1, Ashton Kemerling wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I can answer this in two ways: 1. Acceptance testing Clojure code. 2. Acceptance testing other code with Clojure. I have significantly more experience with the latter than the former. All in all, I prefer the built in clojure.test library over more opinionated libraries like Midje. In particular I recommend adding in Aphyr's excellent Prism plugin to your profiles.clj to do auto testing, and pjstadig`s similarly excellent humane-test-output for readability. My dislike of midje stems from how awkward I found it to share setup code between tests. I feel that clojure.test nests more, allowing me to save more code up front. I also haven't used Midje in a while, so Brian might've upgraded it without me noticing. You also cannot go wrong with test.check. I really enjoy using it for both correctness and simple profiling (e.g. print to console and see if anything gets too slow). On the latter front, test.check + JDBC/Selenium/HTTP appears to be one of the most fruitful ways of hunting down bugs in single-page applications that I've ever seen. I think at this point the bug count for our testing code is close to 5 for an average of 3 hours per bug. Most of these bugs were either concurrency, caching, or SQL based, and some were close to 4 years old.

Re: OT: Github Alternatives

Re: Hosting Providers
Hi Richard Sorry for the delay. We'll check that out! Having said that, my inclination would be to avoid the compile step if we can and just run on top of the leiningen project (e.e. analogous to ruby apps). Putting Engine Yard aside, it raises an interesting question so I am wondering what other people on this list do. Do you compile your code or just run from the sources as you would in development? Many Thanks Adrian On Thu, Apr 24, 2014 at 2:51 PM, Richard Watson rwat...@engineyard.comwrote: Hi Adrian, You don't have far to look ... Engine Yard now supports Java, and by extension, Clojure. If you can package up your Clojure app into a WAR file (using Leiningen's 'lein ring uberwar', for example) you can deploy it onto a Jetty or Tomcat server in an Engine Yard Java environment.

Maybe someone has done it and blogged about it (i haven't looked), otherwise you'll have to figure it out on your own. If you go the AWS route, there is good documentation for configuring Dynamo and deploying a transactor on the Datomic site. Then you could deploy your peer through Beanstalk and you're good to go. That's the route I'm planning to take, but I'm still weeks away from setting up a staging environment. When I do get to that point, I can share my experience and any gotchas I encounter.

not
succeeding. My error must be simple and obvious...
Essentially the projects 'poker' and 'testgen' are both in
/home/simon/workspace, and both are standard leiningen projects using
just
the default project template. I've done 'lein uberjar' in testgen, so
there
are the following jars:
simon@engraver:~/workspace/poker$ ls -l
/home/simon/workspace/testgen/target/
total 3588
drwxr-xr-x 2 simon simon4096 Apr 2 20:04 classes
-rw-r--r-- 1 simon simon 5 Apr 6 00:06 repl-port
drwxr-xr-x 2 simon simon4096 Apr 2 20:04 stale
-rw-r--r-- 1 simon simon 11226 Apr 6 00:10
testgen-0.1.0-SNAPSHOT.jar
-rw-r--r-- 1 simon simon 3646079 Apr 6 00:10
testgen-0.1.0-SNAPSHOT-standalone.jar
In poker/project.clj I've done the following (added lines highlighted):
(defproject poker 0.1.0-SNAPSHOT
:description Poker scoring kata
:url http://example.com/FIXME;
:license {:name Eclipse Public License
:url http://www.eclipse.org/legal/epl-v10.html}
:repositories [[testgen
file:///home/simon/workspace/testgen/target]]
:dependencies [[org.clojure/clojure 1.5.1]
[testgen 0.1.0-SNAPSHOT]
])
When I try to run lein repl, I get the following:
simon@engraver:~/workspace/poker$ lein repl
Could not find artifact testgen:testgen:jar:0.1.0-SNAPSHOT in clojars
(https://clojars.org/repo/)
Could not find artifact testgen:testgen:jar:0.1.0-SNAPSHOT in testgen
(file:///home/simon/workspace/testgen/target)
This could be due to a typo in :dependencies or network issues.
So clearly lein is failing to recognise the jar file(s) as the artefact
it's looking for. What do I need to do differently? Do I need a pom
file,
and if so what should be in it?
Cheers
Simon

Re: OT: Enterprise Schedulers
Hi Luca Thanks for the links! I definitely have a lot of hammock time ahead of me :-) Cheers Adrian On 11 Feb 2014, at 14:37, icamts wrote: Hi Adrian, the answer is more off-topic than the question :) but have a look to Spagic (I'm a member of the developers' team), Mule ESB, Petals ESB or Talend ESB. You may already know Talend as an ETL solution. You'll find tools to define, configure and run instances of services or processes. Monitong application with re-start / re-run facilities. Connectors for services / processes integration. In a ESB scenario developers will design simple processes with a quartz or file polling connector followed by a script / custom component designed to accomplist the batch task. Custom components can be written in clojure if you reify the required interface. The only cavevat is the AOT compilation. Some other ideas are below, along your problem statement. Cheers, Luca Be controlled by artifacts developers control Probably be github friendly Put service deployment directory and estensions / plugins directory under version control and copy them as a part of the deployment process. An ESB can be deployed like a simple webapp. Provide a direct relationship between an application and its tasks Choose meaningful service names. Deploy a local ESB in the same AS of your application and use an in-memory invoker / connector. Support separate sandbox, staging and production environments Use different ESB instances. Be scalable Single task scalability is up to your code. Be distributed - jobs for application X can run on the same host as application X or on a different host or cluster as needed Sevices / processes can be run on every ESB instance. Use in-memory invoker / connector or soap invoker / connector. Be secure Use https for remote connection. Use sftp for file transfer. Be easy to administer Job progress and status is visible Service progress notification is up to your code and not a monitor console feature. Process running step is available. Alert when a job fails Use a mail connector to alert on job fails Easy to re-run a job Restart / rerun through monitoring console. Easy to spin up new hosts and/or move all processing to a different host Deploy a new instance with the same configuration. No running service can be moved. Running processes may be moved. It depends on workflow engine implementation details. Provide a standard way of organising assets like files and configs across all our applications (Not sure what you mean.) Comply with our hybrid infrastructure (stuff runs internally and in the cloud) Data can move internal - cloud Is it an ETL task? Data can move cloud - internal Same as before Data can be processed entirely within a host That's so Support different ways of triggering a job Scheduled tasks Use a quartz input connector Run when file x arrives Use a file poller input connector Run job y after job x completes Use an output connector to trigger the next job start or design a process with jobs in a sequence. -- You received this message because you are subscribed to the Google Groups Clojure group.

OT: Enterprise Schedulers
Hi Everyone, This is a wee bit off topic, but given the sorts of problems the Clojure community likes to solve and the enterprise background of a lot of people I thought this list might be a good place to start. We are building a fairly large web-infrastructure running over a combination of internal and cloud-hosted VMs. It's basically service-oriented, but we have a number of cases where we need to bulk load data from CSV file and largish JSON files. At the moment, we are using cron to run the jobs, but it's not really providing the level of visibility and control we need. I've added my problem statement below and I am thinking of a solution that is something along the lines of a cheaper and more agile-friendly version the enterprise schedulers I used to use when I was building ETL/data warehouse solutions a few years ago. Before I dive in and start building something, does anyone know of any open-source projects and/or libraries I might want to look at? Also, if anyone else is interested in this space, I would love to hook up and bounce some ideas around. Many Thanks Adrian The Problem We need a reusable solution that allows us to schedule, execute and monitor batch processes accross all our applications. It should... - Be controlled by artifacts developers control - Probably be github friendly - Provide a direct relationship between an application and its tasks - Support separate sandbox, staging and production environments - Be scalable - Be distributed - jobs for application X can run on the same host as application X or on a different host or cluster as needed - Be secure - Be easy to administer - Job progress and status is visible - Alert when a job fails - Easy to re-run a job - Easy to spin up new hosts and/or move all processing to a different host - Provide a standard way of organising assets like files and configs across all our applications - Comply with our hybrid infrastructure (stuff runs internally and in the cloud) - Data can move internal - cloud - Data can move cloud - internal - Data can be processed entirely within a host - Support different ways of triggering a job - Scheduled tasks - Run when file x arrives - Run job y after job x completes -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: OT: Enterprise Schedulers
Hi François Thanks for the info. Quartz and it's Clojure DSLs seem to do some of what I need. I had a quick scan of the docs and they don't appear to support triggers that are not time based (on arrival of a file, on completion of a job etc) - but it was only a quick scan so I wondered if you had noticed these facilitates during your investigations? Do let us know what you find out and decide. I definitely will!

I have no idea how quartzite and quartz-clj compare to each other.

Re: OT: Enterprise Schedulers
Hi François I totally agree about the scheduling library being only part of the solution. I'm aware of Pallet but I have never used it in anger. The links you have provided look like an interesting angle. I'll start working through them and see if I can figure out an architecture that meets my needs and I can share with you though this list Many Thanks Adrian On 10 Feb 2014, at 16:59, François Rey wrote: On 10/02/14 16:20, Toby Crawley wrote: Actually, Immutant has its own Quartz integration, and is not based on quartz-clj. You can, however, use the Quartzite API with the cluster-aware Quartz scheduler that Immutant provides if you prefer the Quartzite API over the Immutant one. - Toby Thanks for being more precise, as I said I've have not used any of these libraries, yet (project still in the starting block)... On 10/02/14 14:30, Adrian Mowat wrote: Also, if anyone else is interested in this space, I would love to hook up and bounce some ideas around. A scheduling library would provide much of what's needed for managing these jobs, but that would be at a level which may not be too low for certain use cases, e.g. finer control over job distribution, job composition, exception handling, manual retry, etc. A layer above the scheduler would make sense for this. Recently, while investigating the use of a finite state machine and thus searching for fsm libraries in the clojure world, I ended up looking at a couple fsm libraries used in pallet (http://palletops.com/): - pallet-fsm (https://github.com/pallet/pallet-fsm) - pallet-fsmop (https://github.com/pallet/pallet-fsmop) They are used in the pallet api for managing cloud operations on remote nodes: http://palletops.com/pallet/marginalia/0.8/uberdoc.html#pallet.core.primitives http://palletops.com/pallet/marginalia/0.8/uberdoc.html#pallet.api (see converge method) I don't know if you use pallet but this may be of interest, especially when reading the rationale: https://github.com/pallet/pallet-fsmop/wiki/Rationale An example of usage can also be found in this discussion: https://groups.google.com/forum/#!topic/pallet-clj/ZcBrmUn-mAI From what I understand pallet-fsmop is based on pallet-fsm and provides higher-level operations over sets of fsm that must have certain states for that purpose. These higher-level operations trigger the remote operation encapsulated by each fsm, adding some delay, timeouts, comprehensions, reducers, reporting, etc. So in your case one could imagine a similar library that uses a scheduling library instead of doing immediate or delayed execution. In any case a single library won't satisfy all your requirements, so you will have to choose a scheduling library and compose with others... -- You received this message because you are subscribed to the Google Groups Clojure group.

Why does Clojure at times use Java classes as their base type?
In a broader sense, it's because Clojure was designed to embrace the underlying runtime. As well as eliminating problems with leaky abstractions (as others have pointed out), it also encourages post to other runtimes like the CLR and JavaScript (clojurescript) Does anyone have a link to a Rich Hickey video or article where he covers this off?

Yes, it was the missing clojars deployment. 1.8.0 is up there now. 1.7.0
doesn't have the map representation, which I added to the existing

Re: cider status
Is cider just a new release of nrepl.el or a different thing entirely?

[ANN] exercism.io
Hi Folks I wanted to promote a new site I have been rather hooked on for the past few weeks. http://exercism.io is a crowd sourced/social coding practice site. When you login, you can download an exercise and a test suite. Once you have coded your best solution to the problem, you submit it back up to the site for people to nitpick. You can also nitpick other people's submissions. exercism.io is intended to be a conversation about what good code might look like. There's no right answer, and many good questions. There are exercises in Clojure, Ruby, Elixir, JavaScript, Python and Haskell. Hopefully you will find this useful too Adrian -- -- You received this message because you are subscribed to the Google Groups Clojure group.

I have an event handler that listens for changes in an input element

It works fine. Everytime I type in the input box, some text is
appended to 'test-area'
However, this doesn't work any more when I switch to using for
(event/listen search-input
:keyup
(fn [e]
(let [search-results [a b]]
(for [x search-results] (dom/append test-area (dom/element :p {}

Stepping through the generated code, I noticed that the generated
javascript calls the function with null as the first argument (second
last line below) but I can't figure out why or how to change the
behaviour.

I fell sure I'm missing something fairly basic, but it's escaping me
