Advent Art: Generating Hokusai paintings


Click here to see the result live!

For the last few years, the Japanese F# community has been running the F# Advent Calendar (2010, 2011, 2012). Each advent day, one person writes an article about something interesting in F#. I have been following the advent calendar last year on Twitter and when the planning started for this year, I offered to write an article too. You might have noticed that I posted a Japanse version of the article in December as part of the advent calendar 2013.

A number of people helped to make this happen - @igeta arranged everything and helped with reviewing, @yukitos translated the article and @gab_km reviewed the translation. Thanks!

But what should I write about? It would be nice to look at some of the F# open-source libraries and projects that have been developing over the last year in the F# community. At the same time, can I relate the topic of the article to Japan? After some thinking, I came up with the following plan:

Advent Art:北斎の絵を生成する



ここ数年、日本のF# コミュニティは「F# Advent Calendar」というイベントを開催しています (2010年2011年2012年、 そして 今年)。 これはadvent dayごとに1人ずつ、F#に関連した何かしら興味深い記事を作成するというものです。 私は去年からTwitterでadvent calendarをチェックしていて、 今年からは私も参加しようと思い、記事を書きたいと申し出ました。 そうしたところ、数名の方からの協力を得ることができました。 @igeta には参加手続きの諸々とレビューを、 @ukitos にはこの記事の翻訳を、そして @gab_km には翻訳のレビューをしていただきました。 ありがとう!

けれども何についての記事を書くのがよいのでしょう? 過去一年にわたって、F#コミュニティで開発されているF#のオープンソースライブラリやプロジェクトを いくつか紹介できるような記事がよさそうです。 それと同時に、日本に関連のあるトピックが何かないものでしょうか? 少し考えてみたところ、以下のようなプランを思いつきました:

F# Data: New type provider library

When F# 3.0 type providers were still in beta version, I wrote a couple of type providers as examples for talks. These included the WorldBank type provider (now available on Try F#) and also type provider for XML that infered the structure from sample.
For some time, these were hosted as part of FSharpX and the authors of FSharpX also added a number of great features.

When I found some more time earlier this year, I decided to start a new library that would be fully focused on data access in F# and on type providers and I started working on F# Data. The library has now reached a stable state and Steffen also announced that the document type providers (JSON, XML and CSV) are not going to be available in FSharpX since the next version.

This means that if you're interested in accessing data using F# type providers, you should now go to F# Data. Here are the most important links:

Before looking at the details, I would like to thank to Gustavo Guerra who made some amazing contributions to the library! (More contributors are always welcome, so continue reading if you're interested...)
