Re: Big Excel (xlsx) file parsing (docjure, incanter...)
Hi, I don't think docjure supports streaming options yet - but you can try using Apache POI streaming API - http://poi.apache.org/spreadsheet/index.html - that should help in reading large files.

Re: Clojure in the Large style JDBC library
I've been using clojure.java.jdbc for a while and have been able to get away with the query and execute! functions for most of the work, frequently wrapping them with transactions. All three, from what I recall, give you the option of either using an open connection (very useful for transactions) or to just pass in a map with DB configs that will be used to open a new connection right there and then. I remember switching away from korma and its defdb partially for that reason. On Friday, September 6, 2013 7:43:42 AM UTC-7, Jason Gilman wrote: That's excellent.

It smells like there are vars being held onto by the library that hold database connections or other state. It could still work out if I'm careful about which functions I call. What I'd really like is a library that returns some kind of context object when it connects and all functions that operate on the database take that context as an arguments. This is way more flexible, easier to test and fits more in line with the style I was going for. I'm still curious if there are other people out there who want use that same style and have to work with a relational database.

Re: Introducing a new SQL migration library for clojure / jdbc
This is great, thanks for making it. There was nothing quite like that I could find back when I started on our web app, so I ended using standalone_migrationshttps://github.com/thuss/standalone-migrations, which is essentially ActiveRecord's Migration module extracted for standalone use. Right now it has the advantage over clj-sql-up of supporting multiple environments, but it does unfortunately force you to have ruby support a Gemfile etc, which isn't as awesome as doing everything through clojure. I'll be following clj-sql-up's progress :) On Saturday, July 20, 2013 6:35:29 PM UTC-7, Plinio Balduino wrote: Thank you, Chris I think it will be very useful for my next project.

Re: Handling name collisions with clojure.core
I haven't tried this, so apologies if it couldn't even work, but have you considered providing a fn in your library intended to be used inside the ns macro? The refer-clojure :exclude boilerplate could be replaced with something like this. (ns my-thing (:require core.matrix.ns) (:core.matrix.ns/exclude-clojure-core-math-ops) (:use core.matrix)) It's not too much boilerplate, and probably explicit enough for anyone who was going to :refer :all anyway. (Sorry for butchering your lib's name. Mobile keyboard bad for code.) On Sep 4, 2013 8:22 PM, Mikera mike.r.anderson...@gmail.com wrote: Hi all, While building the API for core.matrix, I've fun into a few cases where the best name is a direct clash with clojure.core. Examples are +, zero?, vector?, == In many of these cases, the core.matrix behaviour is a natural extension of the clojure.core function (i.e. it extends the same functionality to arbitrary N-dimensional arrays). I'm not very happy with any of the options I can see for handling this: A) Use the good names in the clojure.core.matrix namespace. Problem: that gives you a ton of nasty warnings of the type WARNING: + already refers to: #'clojure.core/+ in namespace: test.blank, being replaced by: #'clojure.core.matrix/+. Significant boilerplate must be maintained by the user in their ns declaration to prevent these warnings. I don't like forcing users to maintain boilerplate, and I think that normal idiomatic usage should be warning-free. B) Separate the name-clashing functions into separate namespaces - e.g. clojure.core.matrix.operators. Problem: that's something of an artificial division, and again it forces users to do extra ns-management work to access the functions they want. C) Use different names. Problem: names would be worse, and this would be inconsistent and confusing, especially for functions that do effectively the same thing. D) Encourage users to use aliases. Problem: that's horrendously ugly and inconvenient for numerical code. Users with any sense of elegance in their coding style would quite rightly throw their hands up in disgust.

Pro-tip: you can disable paredit for the next keystroke by typing Esc first

Vote for Clojure on DevDocs
A couple of months ago I discovered DevDocs: http://devdocs.io/ As a developer who has been spending a lot of time with front-end DOM / JavaScript / HTTP / XHR code over the past 6 months, it's been a real boon. The maintainer is using Trello as a mechanism to collect suggestions and votes for what libraries, languages and tools should have their documentation ported into DevDocs: https://trello.com/b/6BmTulfx/devdocs-documentation Back in late August, I requested that Clojure be added to the voting-list, but didn't notice until yesterday that he did add it, in the [Other] list. *If you would like to see Clojure's docs available through DevDocs, please go vote for it!* It may be some time before the maintainer gets around to it, but he does seem quite responsive when the votes tally up for a particular entry. Perhaps some other popular Clojure-related APIs could be suggested as well: ring, Datomic, etc. In the long run, I hope the maintainer will open source the DevDocs platform and some docs-contribution mechanism (it's not an open platform at present), but I find it to be a very practical and useful tool in any case.

Re: Clojure in the Large style JDBC library
If you have any feedback on the new API in the 0.3.0-alpha4 release, let me know. The whole point of the API rewrite in 0.3.0 was to move away from the *db* global dynamic variable, and deprecate all the old stuff. Getting a final release of 0.3.0 is taking longer than I had hoped - apologies - but it's a lot of API churn and I want to make sure we've covered all our bases before 0.3.0 goes out so I don't have to make breaking changes again in the near future. The main change holding up 0.3.0 is deciding exactly what to do with transactions. I want to move away from the boolean :transaction? argument to a function-based :transaction-fn argument instead so more general transaction logic can be used. I also want to support a little more in the DDL area before 0.3.0 goes out.

It smells like there are vars being held onto by the library that hold database connections or other state. It could still work out if I'm careful about which functions I call. What I'd really like is a library that returns some kind of context object when it connects and all functions that operate on the database take that context as an arguments.

The problem is most Clojure functions don't use core.type nor are type

Hey guys,
I don't know about you but when I was a beginner in Clojure (and it still
happens every now and then) I had a hard time finding functions using `doc`
or `find-doc`,
normally because I didn't remember the name of the function or because my
only clue was a generic name so find-doc would return too much results. But
one
thing I knew: what to expect of the function, I knew the inputs and the
outputs. That's why I decided to create wally, because sometimes you don't
know the name of the function you want but you know how it should behave.
With wally you can tell the inputs and the output and it'll search for
functions that match those inputs/outputs.
Ex:
user= (find-by-sample {1 1, 2 3, 3 1, 4 2} [1 2 3 4 4 2
2])-clojure.core/frequencies([coll])
Returns a map from distinct items in coll to the number of times
they appear.
user= (find-by-sample '((1 2 3) (4 5)) (partial 3) [1 2 3 4 5])
-
clojure.core/partition-by
([f coll])
Applies f to each value in coll, splitting it each time f returns
a new value. Returns a lazy seq of partitions.

thing I knew: what to expect of the function, I knew the inputs and the
outputs. That's why I decided to create wally, because sometimes you don't
know the name of the function you want but you know how it should behave.
With wally you can tell the inputs and the output and it'll search for
functions that match those inputs/outputs.
Ex:
user= (find-by-sample {1 1, 2 3, 3 1, 4 2} [1 2 3 4 4 2 2])
-
clojure.core/frequencies
([coll])
Returns a map from distinct items in coll to the number of times
they appear.
user= (find-by-sample '((1 2 3) (4 5)) (partial 3) [1 2 3 4 5])
-
clojure.core/partition-by
([f coll])
Applies f to each value in coll, splitting it each time f returns
a new value. Returns a lazy seq of partitions.

How do you configure your Ring apps?
I'm curious to find out how you folks decided to organize configuration for your Ring applications, assuming you also use configuration management like Puppet/Ansiblet etc to deploy them. So far I've been using a combination of daemontools' envdir (through runit) + weavejester's environ https://github.com/weavejester/environ for things like db address, db password, cookie secret keys, logging level etc. Each one is an individual file in root-only folder that runit envdirs from. I honestly can't decide whether a single configuration file (YAML, EDN, whatever) would be more appropriate for this scenario or if I should go ahead and continue keeping each configuration value in its own file and use env to load them. What are people's thoughts on this? Any reason why one or the other would be better, or is there an even better option out there I'm not considering? -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Significantly faster incremental ClojureScript auto builds
In hunting down a ClojureScript bug I ended up fixing one of the biggest bottlenecks in incremental ClojureScript builds. If you use this branch http://github.com/clojure/clojurescript/compare/509-protocol-warn you should see up to 10X faster incremental builds in some cases. We're now avoiding analyzing files that haven't changed when you're doing incremental builds. Feedback and issues welcome, I would like to merge this into master and cut a release with this enhancement as soon as possible.

Re: How do you configure your Ring apps?
I use environ as well. I don't use config files and don't think they're a great idea. Instead I use a simple config.clj that pulls stuff from environ into one big get-config map. I use (or (env :env-var) fallback-value) for each variable.

You can use it in production, but I'd override the ansi boolean to shut off the special characters for coloration. Set *use-ansi* to false in the clansi namespace.

ring 1.2.0 setup
I am following the book 'Clojure Programming' and have some questions on
setting up ring.
I have been using the latest versions of ring version 1.2.0. Also using
compojure, enlive but taken them out for this post.
...
The Clojure project is set up fine and imports libraries and gives no
problems in Eclipse.
I am using JDK 1.7 on Ubuntu 13.04.
(defproject startingclojure 0.1.0-SNAPSHOT
:description FIXME: write description
:url http://example.com/FIXME;
:license {:name Eclipse Public License
:url http://www.eclipse.org/legal/epl-v10.html}
:dependencies [[org.clojure/clojure 1.5.1]
[ring 1.2.0]])
Ring libraries are imported fine. I have compojure and enlive also as part
of project but not shown here.
No errors in Eclipse.
...
I have tried various approaches but my require is as you shown:
(ns startingclojure.app
(:require [ring.adapter.jetty :as jetty]))
...
However my jetty just won't run:
(def server (jetty/run-jetty #'app {:port 8080 :join? true}))
Always gives this error:

Re: How do you configure your Ring apps?
I'm only starting out with Clojure/Ring, but I was thinking about this recently too. I had something like the following in mind, borrowing some concepts from other projects/frameworks/strategies that I've had success with. The project could contain something like 'config/global.clj' which contains a simple Clojure map with configuration for your app that is appropriate for version control. Maybe it has some default values, comments, etc. You could build this in to your app somewhere, too. The project would then have another Clojure map in a file named like 'config/local.clj' in your project root which would be ignored by version control, and deployed alongside your application. You'd probably template it with Puppet or Chef or Ansible and it would contain your deep, dark secrets. You'd have a project-local one of these for development. You could even have more than one, if that's your thing. At application initialization, the maps are then read in, merged and made available to your application exactly like weavejester's environ that you mentioned. environ already handles leiningen profiles for things like AWS access keys which might be annoying to duplicate across all of your projects in development, and such a system as I've described would fit in fairly naturally with environ. In any event, I hadn't found that project yet, but I definitely plan to use it now. Thanks for pointing it out!
