読めるランダム文字列を作る

readme.md

ランダムだけど読みやすいのがいい
⇩
漢字や熟語の読みのひらがな 2 文字をローマ字化して欲しい文字数分くっつける

「星」とか「風」とか「仮名」とか「記事」とか、読みが 2 文字ずつの読める言葉になってるのでアルファベット並んでるだけでも比較的読めるはず

手順

言葉は mecab-ipadic の辞書から取リ出す

言葉の文字すべて日本語・読みが 2 文字・「ッ」は含まない、という条件で取り出してローマ字変換してパーツを作る
欲しい文字数になるまでパーツからランダムに取り出してくっつける

1. make-parts.py でパーツの txt ファイルを出力
2. その結果が strparts.txt
3. strparts.txt と words.html をサーバの同じフォルダに置く
4. words.html にブラウザでアクセス

20 文字くらいの例（ローマ字化で文字数が一定じゃなくなるので少しオーバーする）

• merihikuchizuseyotsutsu
• noterouichikagigetachiho
• jigarijiudaokootarisa
• usadobusuyaeranotenoge
• moshiyojiterotabosegi
