Publish a post titled \u304a\u77e5\u3089\u305b in WordPress and the permalink becomes\n \/%e3%81%8a%e7%9f%a5%e3%82%89%e3%81%9b\/. It works, but it is unreadable in a\nbrowser bar, it breaks when pasted into chat, and it is useless in a report.\nThe usual fix is to type an English slug by hand for every single post, and the\nusual result is that somebody forgets.<\/p>\n\n

Robse Auto Alpha Slug fills the slug in for you when you save. Kana are romanized, so\n\u304a\u3057\u3089\u305b becomes oshirase<\/code> and \u30c7\u30a4\u30b5\u30fc\u30d3\u30b9 becomes deisabisu<\/code>. A slug you\ntyped yourself in plain ASCII is always left alone.<\/p>\n\n

Kanji are handled honestly<\/h4>\n\n

This is where other plugins quietly go wrong. PHP has no reliable way to read\nkanji: the ICU transliterator that most plugins call reads them as Chinese<\/strong>,\nso \u6751\u677e comes out as cun-song<\/code> and \u51fa\u96f2\u305d\u3070 as chu-yunsoba<\/code>. That is not a\nslug anybody wants, and it is worse than no slug at all because it looks\ndeliberate.<\/p>\n\n

So this plugin does not guess. When a title contains kanji it cannot resolve,\nit uses a predictable pattern instead \u2014 post-123<\/code> by default \u2014 and leaves the\nguessing to you:<\/p>\n\n

    \n
  • Fallback (default).<\/strong> A clean, predictable slug such as post-123<\/code>.<\/li>\n
  • Drop the kanji.<\/strong> Build the slug from the kana and Latin text that remain.<\/li>\n
  • Transliterate.<\/strong> The ICU behaviour described above. Correct for Chinese\nsites, wrong for Japanese ones, and labelled as such in the settings.<\/li>\n<\/ul>\n\n

    A dictionary for the words you actually use<\/h4>\n\n

    Company names, place names and people's names come up again and again on one\nsite. Teach them once:<\/p>\n\n

    \u51fa\u96f2 = izumo\n\u7f8e\u98df\u65c5 = gourmet-trip\n\u6751\u677e\u82f1\u4fca = muramatsu-hidetoshi\n<\/code><\/pre>\n\n
    Now \u51fa\u96f2\u305d\u3070 \u7f8e\u98df\u65c5 becomes izumo-soba-gourmet-trip<\/code> instead of falling back.\nLonger terms win over shorter ones, so \u51fa\u96f2\u5e02 can differ from \u51fa\u96f2.<\/p>\n\n
    No intl extension required<\/h4>\n\n
    The kana table is built into the plugin, so romanization works the same on a\nserver without the intl extension. Sokuon and youon are handled: \u307e\u3063\u3061\u3083\nbecomes matcha<\/code>, \u304e\u3085\u3046\u306b\u3085\u3046 becomes gyuunyuu<\/code>.<\/p>\n\n
    Everything else<\/h4>\n\n
      \n
    • Choose which post types are handled, or let the plugin detect them.<\/li>\n
    • Cap the slug length, cut on a word boundary.<\/li>\n
    • Try a title on the settings screen and see the slug before you publish\nanything.<\/li>\n
    • Decide whether percent-encoded slugs are replaced or left as they are.<\/li>\n<\/ul>\n\n\n
        \n
      1. Install and activate the plugin.<\/li>\n
      2. That is enough for kana titles. Nothing else is required.<\/li>\n
      3. To change how kanji are handled, or to add dictionary entries, go to\nSettings \u2192 Robse Auto Alpha Slug<\/strong>.<\/li>\n<\/ol>\n\n
        Existing posts are never touched. Only posts you save after activating get a\ngenerated slug, so your current permalinks and their search rankings stay as\nthey are.<\/p>\n\n\n
        \n
        Will it overwrite a slug I typed myself?<\/h3><\/dt>\n
        No. A slug written in ASCII letters, digits, hyphens or underscores is treated\nas deliberate and kept, whatever the title says.<\/p><\/dd>\n
        Will it change the slugs of my existing posts?<\/h3><\/dt>\n
        Not on its own. Slugs are only generated when a post is saved. If you open an\nold post with a percent-encoded slug and save it, the slug is replaced \u2014 turn\noff Replace slugs that arrive percent-encoded<\/strong> in the settings if you would\nrather that never happened.<\/p><\/dd>\n
        Why does my kanji title become post-123 instead of romaji?<\/h3><\/dt>\n
        Because a wrong reading is worse than no reading. See the description above.\nAdd the words to the dictionary, or switch the mode to Drop the kanji<\/strong>, and\nyou will get a text slug.<\/p><\/dd>\n
        Does it work with custom post types?<\/h3><\/dt>\n
        Yes. By default every post type with an editing screen is handled. You can\nrestrict that on the settings page, or with the robse_auto_alpha_slug_post_types<\/code>\nfilter.<\/p><\/dd>\n
        Can I change the generated slug from my own code?<\/h3><\/dt>\n
        Yes, filter robse_auto_alpha_slug_generated<\/code>:<\/p>\n\n
        add_filter( 'robse_auto_alpha_slug_generated', function ( $slug, $title, $post_type, $post_id ) {\n    return 'news-' . $slug;\n}, 10, 4 );\n<\/code><\/pre><\/dd>\n\n<\/dl>\n\n\n
        2.0.0<\/h4>\n\n
          \n
        • Kanji are no longer transliterated as Chinese by default. Titles containing\nkanji now use a predictable fallback pattern, and the old behaviour is still\navailable as an option.<\/li>\n
        • Added a settings screen: kanji handling, fallback pattern, dictionary, post\ntypes, maximum length, and a preview field.<\/li>\n
        • Added a user dictionary so recurring names and places romanize correctly.<\/li>\n
        • Kana romanization no longer depends on the intl extension.<\/li>\n
        • Fixed \u30f4\u30a1\u30a4\u30aa\u30ea\u30f3 and similar katakana producing stray characters in slugs.<\/li>\n
        • Renamed internal classes and hooks to a unique prefix. The old\n  rm_auto_alpha_slug_post_types filter still works.<\/li>\n<\/ul>\n\n
          1.6.0<\/h4>\n\n
            \n
          • Kept manually entered ASCII slugs untouched.<\/li>\n<\/ul>\n\n
            1.0.0<\/h4>\n\n
              \n
