階層構造が見やすい見出しを出すユーザースクリプト
/shokai/ページの見出しを作るUserScript を改変しました
こんな感じ
使い方：自分のscrapbox内の /your_user_name に下の
script.js を貼る script.js(function () {
scrapbox.PageMenu.addMenu({
title: '見出し',
image: 'https://gyazo.com/bc38721e0980f2188f1c831754ac8da4/raw',
onClick: () => {
scrapbox.PageMenu('見出し').removeAllItems()
var deepest = 0;
for (let line of scrapbox.Page.lines) {
if (!line.section.start) continue
var depth = line.nodes ? calcDepth(line.nodes) : 0
if (deepest < depth) deepest = depth
}
console.log('deepest index is ' + deepest)
for (let line of scrapbox.Page.lines) {
if (!line.section.start) continue
const image = line.nodes && getIconUrl(line.nodes)
const noIcon = !!image
const title = line.nodes ? renderPlainText(line.nodes, {noIcon, level: 0}, deepest) : line.text
const onClick = () => location.hash = line.id
scrapbox.PageMenu('見出し').addItem({title, image, onClick})
}
}
