3.0.xのデータを抽出し、DataFixtureで読み込み可能なCSVへ変換する

以下の操作で3.0.xデータを3.nで移行できるようにする(イメージ)

cd /path/to/eccube30
php app/console convert::3n /path/to/eccube3n/src/Resouce/doctrine/import_csv

One line Tree in Groovy

The other day, I saw Harold Cooper's One-line tree in Python via autovivication, and wondered if the same thing was possible in Groovy.

The answer is yes! But you need to define the variable tree before you can assign it to the self-referential withDefault closure, hence with Groovy, it's a two-line solution ;-)

Anyway, given:

def tree = { [:].withDefault{ owner.call() } }
