Update minified YUI to version 2.9 built from Source. yui.2.9.js used to be a minified version of YUI 2.9 until 5143b8df576c updated it to something else and applied more aggresive minification. We stick to a clean but minified version 2.9. The license of YUI is BSD 3-clause, as described on http://yuilibrary.com/license/ . Since the minified version combines with GPLv3'd Javascript, it is only GPLv3'd compliant to distribute this Object Code version with the Corresponding Source (or offer therefor). This yui.2.9.js is built from Source this way: git clone https://github.com/yui/builder git clone https://github.com/yui/yui2 cd yui2/ git checkout hudson-yui2-2800 ln -sf JumpToPageDropDown.js src/paginator/js/JumpToPageDropdown.js # work around inconsistent casing rm -f tmp.js for m in yahoo event dom connection animation dragdrop element datasource autocomplete container event-delegate json datatable paginator; do rm -f build/$m/$m.js; ( cd src/$m && ant build deploybuild ) && sed -e 's,@VERSION@,2.9.0,g' -e 's,@BUILD@,2800,g' build/$m/$m.js >> tmp.js done java -jar ../builder/componentbuild/lib/yuicompressor/yuicompressor-2.4.4.jar tmp.js -o yui.2.9.js The source is mirrored and available on https://kallithea-scm.org/repos/mirror .
