ビーチをさんぽします

ビーチへ行きました。

ながいあしはやさしいです。でも、みじかいあしは…

ドットさん「とてもこうふんしています」

日の入りはきれいでした。

かっぱやの昼ごはん。そしてもっと動物。

今週末もっと動物を見ました。

そのまえに、日本のきっさてんで昼ごはんを食べました。かっぱやといいます。

きれいなきっさてんです。そとにいました。

お茶をのみました。

かないの昼ごはん。私のとほとんどおなじでした。

おにぎり。まえはつけものとうめぼし。（私はうめぼしが大すきです）。そのうしろはさけです。

Deep fried やさい。サコサコともうします。

いつドットは食べ物をもらいますか？わかりません！

食べたあとで農場（のうじょう）の動物を見ました。

ドットちゃんのはじめの羊（ひつじ）…

と牛（うし）…

と豚（ぶた）…

と山羊（やぎ）。

ドットちゃんは豚がこわかったです。でも楽しみました。

ウェッリビの動物園

今週末、ウェッリビの動物園へ行きました。そこにたくさんアフリカの動物がいます。

これはミーアキャト。

この大きいな猫はServalです。とても可愛いいです。

このライオンはちかくなかったから、うれしいです。このちゃしんはちょうどキスがおわったところです。

ウェッリビの動物園は楽しいです。はじめていきました。

（私の日本語はわるいです。あたらしい学生ですから。すみません）

毎週、日本語のレッスンのあとで、犬とあそびたいです。たのしいですから。

Jenkins Git-plugin on Windows pauses when cloning.

If you have Jenkins & Msysgit on Windows, and you find that the git-plugin is pausing at the cloning stage, it is likely that the ssh child process is blocking for input.

Ensure that sure your ssh keys are in the correct location and that they don't require a password.

To find the correct location, in Process Explorer switch to tree view, and locate the stalled ssh.exe child process of Jenkins. Drill into it and confirm the HOME environment setting. This is where your .ssh folder should be located. For me it was c:\documents and settings\{username}\

The truth is that Scala is brilliant and there's no way around that simple fact.

Book reviews never change my mind. That is until I read this review of DSLs in Action. I will buy this book.

Option's hidden gem

Did many people know about Option.apply before a few days ago? If my twitter stream is any indicator, it was a hidden gem waiting to be uncovered.

It was (welcome) news to me.

When integrating Scala with Java I often need to bridge a null to an Option type. It's important to convert nulls to Options because having nulls littering your logic means you can't trust your variables to be of the type declared; they might be null, and you have to check them with boilerplate if (x == null) checks at every turn.

Previously I was implementing this boilerplate pattern at every join between Scala and Java code where the latter might inject nulls into my logic.

The buzz that went around twitter was that this pattern already exists on the Option object.

SBT plugin updates

How, oh how could I have forgotten SBT-GH-Issues? It allows management of github issues via SBT. This is the plugin that initially got me thinking ‘what other wonderful jewels are out there’?.

Since I wrote my last post, the Jenkins CI plugin has diverged from the Hudson version. (It’s been updated by @uzi_landsmann)

And then there’s a newly emerged code coverage plugin “name_pending”. It’s in beta and there has been at least one report of it not working well. But it’s early days yet, and I have hope in it.

Plugins for SBT

SBT, the Simple Build Tool, has excellent plugin support. The official list of SBT plugins is on the SBT Wiki. I suspect it is not entirely up-to-date.

Here’s a list of plugins currently available. Some I have used personally, most I have not.

IDE/Tooling Support

Create IDEA project files SBT-IDEA
Create Eclipse project files SbtEclipsify
Generate config files for JRebel with JRebel plugin by Joonas Javanainen

Testing

Execute Cucumber features via cuke4duke Cuke4Duke SBT plugin by @rubbish (Don’t forget SBT already has testing support built in Specs, ScalaTest and ScalaCheck if these suit your needs better).

Build Artefacts

HTML formatted sources with rich syntax highlighting and links Scala XRay (SXR) by Mark Harrah (the author of SBT)
Publish aforementioned SXR files to sourced.implicit.ly with SXR Publish by @n8han (Authorisation is required)
Publish your release notes to any Posterous site with Posterous-SBT by @n8han
Give your classes a good shakedown using Proguard SBT-Proguard by @nuttycom
Minify your CSS/JS via YUI with sbt-yui by Jon Hoffman
Edit files ala Ant’s filters with EditSource
Create OSGi bundles with BND4SBT by @weiglewilczek (organisation)
Create different artefacts for different target environments with SBT Filter Plugin by @wong_jim
Turn your entire project into an installer (executable JAR) with SBT Installer Plugin from SBT itself (this looks awesome)
Alternatively, create an IzPack installer with IzPack SBT Plugin
Create HTML from Markdown with (Markdown Plugin)[http://software.clapper.org/sbt-plugins/markdown.html]
Generate widgets for Vaadin SBT-Vaadin Plugin by Joonas Javanainen

Code Metrics

Copy and Paste detector plugin by @johofer
FindBugs plugin (for Java sources only) by @johofer

Deploying

Deploy to stax.net (now cloudbees.com) sbt-stax-plugin by @timperrett
Deploy to Google AppEngine sbt-appengine-plugin by @yasushia
Build for and publish to Android devices Android-Plugin by @jberkel

Polyglot

Integrate Jython with Jython SBT Plugin by Mark Chadwick
Write Processing sketches in Scala with Spde

Continuous Integration

Still using Hudson? Hudson SBT Plugin
^Hudson^Jenkins Jenkins SBT Plugin (I’m not sure if these differ at all currently, but I’d not be surprised if they diverged over time).

I’m sure to have missed a few. If so, let me know. Or better still, head over to the SBT Wiki and update it.

To keep up with new plugins (and libraries) as they are published, I recommend a subscription to implicit.ly
