どれだけ速く文字列からスペースを削除できるのか | POSTD
時によってプログラマは文字列から不要な文字を取り除きたい場合があります。例えば、テキストの一部からすべての行の末尾文字を削除したいとします。 その時、全スペース(‘ ‘)や改行コード(‘\n’および‘\r’)を削除する問題を考えてみましょう。 効率的に実行するにはどのような方法がいいのでしょうか。 size_t despace(char * bytes, size_t howmany) { size_t pos = 0; for(size_t i = 0; i < howmany; i++) { char c = bytes[i]; if (c == '\r' || c == '\n' || c == ' ') { continue; } bytes[pos++] = c; } return pos; } 上記のコードはUTF-8でエンコードされた文字列で動作します。UTF-8がASCII

CS2 Discussion: Project: Progress as of February 2017: 2.0.0-alpha1! · Issue #71 · coffeescript6/discuss
Hey everyone, CoffeeScript 2.0.0-alpha1 is released! Install it via: npm install coffeescript@next You may notice that it’s not at coffee-script. The powers that be at NPM were kind enough to release the coffeescript package name to us. Since no one really spells CoffeeScript with a hyphen anymore, it seemed a better choice. It has both the old versions and 2.0.0-alpha1, and will be the home for f
