利点
vscodeの拡張機能のコアファイルは保存場所が既に決定されており，それが使うパスの書き換えは表からはほぼできない
なので内部のスクリプトを弄ってmarkdown pdf関係の書類をクラウドなどで共有できるようにした，これならコピペ不要
さらにどの場所でmarkdown pdfをやっても必ず同じ結果が得られるようになる，ただしvscodeの環境設定で弄れる範囲を除く
欠点
vscodeの環境設定にパラメータを追加できるのは開発者だけらしく大元ディレクトリのフルパスとプラグインのリストアップはextension.jsに書き込む必要があり面倒
概要
そこそこに改変した
まずmarkdown pdf拡張機能のコアファイルのextension.js（ここの最後の方でいじってたやつ）を以下でコピペして上書きする，だいたい1050行くらい
次にmyGroundPathとmyPluginListをその冒頭箇所に指示通りに書き込む，Windowsではエスケープ処理を忘れないように
更に関係ファイルはmyGroundPathの配下に（例として）以下のように設置する，プラグインは同名のcss・html・jsをそれぞれ必ず配置してmyPluginListとの対応を必ず確保しておく
最後にbase.htmlも間違えずにコピペする，コレで終わり
.
├── base
│ └── base.html
├── plugins
│ └── math
│ ├── math.css
│ ├── math.html
│ └── math.js
├── template
│ ├── template.css
│ ├── template.html
│ └── template.js
└── test
├── test.html
└── test.md
ここのmathとはmarkdown pdf上でkatexを動かすのに必要な設定やマクロなどを集めたもので，導入スクリプトと設定スクリプトで分けてある
そっちの周りのお話はここを参考にしてほしい
ソース
以下はbase.html
<!DOCTYPE html>
<html>
<head>
<title>{{{title}}}</title>
<meta http-equiv="Content-type" content="text/html;charset=UTF-8">
{{{frame}}}
{{{style}}}
{{{script}}}
{{{mermaid}}}
<script>
// insert your test script!
console.log("rendered from base.html!");
</script>
</head>
<body>
<script>
mermaid.initialize({
startOnLoad: true,
theme: document.body.classList.contains('vscode-dark') || document.body.classList.contains('vscode-high-contrast')
? 'dark'
: 'default'
});
</script>
{{{content}}}
</body>
</html>
ここの{{{example}}}などに中身を突っ込むためのテンプレートエンジンはmustache.js，と言うよりextension.jsも含め拡張機能全体がnodeで動作しているっぽい，それはそうか

感想
readCssからmakeStyleが出てくるの違和感がありすぎるのでreadStyleにしてやった，それらと同様の流れでframe（htmlファイル）とscript（jsファイル）を扱えるようにした，あと変更する範囲でvarの使用をなるべくやめさせた，変数宣言で型を明示したくなった，なぜかvscode上でコンソールが表示されなかったがvscode.window.showErrorMessageは役立った，ブラウザでコンソール見るのは大事だと思った
