Github ソースコード表示の印刷をキレイに

Last updated at Posted at 2017-02-13

Githubにあるソースコードを印刷して納品物とする為に、印刷レイアウトを調整する JavaScript を作ってみました。
元ネタは http://qiita.com/htkymtks/items/63decc78dbd14f7fc860 です。

ChromeでJavaScriptコンソールを開いて以下のコードを実行します。
印刷に都合が悪かったソースコードが折り返しされます。

[
	"header",
	"reponav",
	"commit-tease",
	"file-header",
	"select-menu",
	"branch-select-menu",
	"BtnGroup",
	"repohead-details-container",
	"site-footer-container"
].forEach(function (className) {
	document.getElementsByClassName(className)[0].style.display = "none";
});
var codeTags = Array.from(document.getElementsByClassName("blob-code-inner"));
codeTags.forEach(function (e) {
	e.style["word-break"] = "break-all";
	e.style["white-space"] = "normal";
});
