Cascadia Code PL と Migu Nerd Font の違い

注意: アイコンフォントのコピペを多用しているので、対応していないフォントを使われている豆腐が見えます。

TL;DR

これはズブのフォント素人による try&error なので大いに間違っている可能性もある。

結論から言うとまだ納得の行く改造版 Migu の作成には至っていない。

Cascadia も Hack も Narrow な Powerline グリフが埋め込まれているっぽい。ここに来て Migu に直接 Narrow な Powerline グリフを埋め込んだらええやんけ、という Nerd Fonts 回帰案が浮上した(うまく行った試しないのだけど)。

To be Continued...

Migu の良さはそのスリムでシンプルな見栄えだけでなく、Proportional と Monospace で同じ字体を使えることだ。しかし最近の開発環境で使うにはアイコンフォントが同梱されないことで不便を感じることが多い。特に Powerline を使っているとアイコンフォントは必須。ということで 5 年ほど前から iij/fontmerger を使って Nerd fonts などを追加した自作フォントを使っている。

しかしこれがここ 1,2 年くらいで Windows Terminal を使い始めたことで納得いかない点が出てきた。 "Ambiguous"なフォントについては全部 Narrow サイズになる ≒ Certain なフォントについてはサイズが適用される？だと？

TermControl: force all ambiguous glyphs to be narrow by DHowett-MSFT · Pull Request #2928 · microsoft/terminal

Windows Terminal とともに提供される Cascadia に関してはどうもこの問題が発生しない。Powerline グリフに関しては完璧なのだ。

フォント素人のわたしはこの時こう考えた。

改造 Migu と Cascadia でコードポイントは同じだけどフォントを切り替えるだけで表示サイズが異なってくる。 → つまり Cascadia フォントでは、コードポイント0xE0B0とかになんかの情報を入れ込んでるのではないか？と...！

グリフのサイズを目視確認するための一覧用コード。

# Helper function to show Unicode character
function U {
    param
    (
        [int] $Code
    )

    if ((0 -le $Code) -and ($Code -le 0xFFFF)) {
        return [char] $Code
    }

    if ((0x10000 -le $Code) -and ($Code -le 0x10FFFF)) {
        return [char]::ConvertFromUtf32($Code)
    }

    throw "Invalid character code $Code"
}

# 数値は[Convert]::ToInt32('0xE080', 16)でHEX変換する
((170..61278) | %{U $_}) -join ''

全然わからない...クソむずすぎる。でも特定のグリフを移植するだけなら、元々改造 Migu を作るのに使っていた fontmerger が利用できる。とおもてたら DEPRECATED になっておった、そら Python2 やからな...

とりあえず最終目標までの段階的目標を立てた。

お亡くなりになられた fontmerger を Python3 化して動かす
最新の Migu に対して fontmerger で Nerd font patch する
0xE0B0 を始めとした Cascadia でだけうまく表示されるグリフを Migu に移植する
完璧な Migu の完成！

Cascadia を CLI で簡単に落としてくる方法はないものか？

フォントの拡張子がわからなくなったのでおさらい。

otf ... Open Type Font
- Adobe と MS で作った。MS 商標。今や一般的。リガチャ使うならこっちしか無理
ttf ... True Type Font
- Apple 作った。プラットフォーム互換がない
woff ... Web Open Font Format 2
- Web

ここで対象になるのは MonoPL(monospace の PowerLine 版)。まだリガチャを受け入れるだけの心のゆとりができていない。

次に [Migu][https://mix-mplus-ipa.osdn.jp/migu/] を落とす。OSDN のリダイレクトかまされ迂回方法がわからないので手で落とした。

fontmerger のスクリプトがちょっと Windows では使いにくそうに見えたので、一旦 Ubuntu(WSL2)でやる。

でも Ubuntu16LTS の fontforge は 2019 年までのやつで古かったので、一旦 WSL2 の Ubuntu を更新することにする。

sudo apt update
sudo apt upgrade
sudo do-release-upgrade

途中で sshd_config が編集されとんぞ！？と言われて新しいのとローカルのどっち使うか選ばねばいけなかった。ここは新しい方を有効化。この流れで Ubuntu20LTS まで上げた。 Ubuntu20 では fontforge はデフォルトのパッケージではなくなったので、パッケージソースを追加する必要がある。

Ubuntu – Details of package fontforge in focal

universe にあるのがわかったので追加。

sudo apt-add-repository universe
sudo apt update
sudo apt install fontforge

mkdir ./patched
./bin/fontmerger --all -o patched --suffix=with-icons -- migu-1m-regular.ttf migu-1m-bold.ttf migu-1c-regular.ttf migu-1c-bold.ttf

結果、無反応。

警告出るがフォントの生成完了。開いてみるも、いやフォントが壊れてるわ...なんでや？

理由がわかった。fontmerger の実行後に出力先フォルダからフォントを移動するとプレビューできる。出力先フォルダに fontforge の謎のハンドルが残っている様子。

fontmerger の Python3 化が完了した。GitHub - krymtkts/fontmerger: FontForge script for to merge any fonts

Cascadia には Powerline の拡張グリフくらいしか入っていないので Powerline の部分を抜き出して Migu にコピーする。

/usr/bin/fontforge -script fontmerger/__init__.py --all -o patched --suffix=cascadia -- ./source/migu-1m-regular.ttf ./source/migu-1m-bold.ttf ./source/migu-1c-regular.ttf ./source/migu-1c-bold.ttf

結果は Cascadia からコピーした領域は以前 Ambiguous なままだった...なんでだろう。以下が追加の Cascadia からコピる設定。

{
    "id": "cascadia-powerline",
    "name": "Cascadia Powerline Symbols",
    "description": "Powerline symbols copied from Cascadia Code. https://github.com/microsoft/cascadia-code",
    "filename": "./fonts/cascadia/CascadiaCodePL-Regular.otf",
    "unicode_range": [
      "E0A0",
      "E0D4"
    ]
  },

コピっても解消しないのか...と思ってた矢先、フォカのフォントを参考に調べていて GitHub - yuru7/HackGen: HackGen is Japanese programming font which is a composed of Hack and GenJyuu-Gothic. なるフォントを見つけた。

あれ、このフォント Powerline グリフが Windows Terminal でも崩れないし、見た目も結構好みでこれちょっとよいかも...と浮気しそうになるも、やはり字幅の広さが気に入らず Migu に返り咲くワイ。

それはそうと Powerline グリフが崩れないのはなんでか？と思ってみてたところ、これ Symbol フォントが Narrow スペースなのね。Cascadia もそう。つまり問題なのはフォント幅じゃね？と気づく。更に々々、Nerd Fonts から提供されている Hack を使うと、PowerShell モジュールの Terminal Icons で表示されるファイルアイコンすらも小さくならずに表示できるではないかい！これやろ答え。

数年前に試してうまくいったことがないのが心配のタネだが、ここは原点回帰して Nerd Fonts の font-patcher で Migu に Narrow スペースでパッチしてみるか～という気持ちになった。

現状

ただ単に Migu の最新版にパッチしただけの状態になっているのだが、途中経過をまとめておかないと着手する時加齢に忘れてて辛いので一旦状況をまとめた。

お亡くなりになられた fontmerger を Python3 化して動かす
最新の Migu に対して fontmerger で Nerd font patch する
0xE0B0 を始めとした Cascadia でだけうまく表示されるグリフを Migu に移植する
- そして効果なし！
Nerd Fonts の font-patcher で Migu にパッチしてみる <- NEW!!!
完璧な Migu の完成！

俺たちの戦いはこれからだ！😭😭😭
