Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@kappan/plugin-heading-number

見出しの自動採番プラグイン。章(h1)に「第N章」、節(h2 以下)に「N.M」「N.M.K」を付ける。

  • # はじめに第1章 はじめに
  • ## 背景1.1 背景
  • ### 詳細1.1.1 詳細

章番号は spine 順(章ファイルの並び)で採番するため、番号を持たない素の見出しだけの本でも 多章で正しく連番になる。既に「第N章」を書いている見出しはその番号を尊重する。

Installation

pnpm add @kappan/plugin-heading-number

Usage

import { defineConfig } from '@kappan/core';
import { headingNumber } from '@kappan/plugin-heading-number';

export default defineConfig({
  // ...
  plugins: [headingNumber()],
});

Markdown Example

# はじめに

## 背景

### 動機

出力:

  • # はじめに第1章 はじめに
  • ## 背景1.1 背景
  • ### 動機1.1.1 動機

採番したくない見出しには {-}(または {.unnumbered})を付ける:

## 謝辞 {-}

Options

headingNumber({
  labelStyle: 'jp', // 'jp' (第1章 / 1.1) | 'en' (Chapter 1 / 1.1)
  numberChapter: true, // h1 に「第N章」を付ける(既定 true)
  maxDepth: 3, // 節番号を振る深さ(2〜4、既定 3 = h2・h3)
  startNumber: 1, // 開始章番号(既定 1)
  separator: ' ', // 番号と本文の区切り(既定: 和=全角空白 / 英=半角空白)
});

Notes

  • 章番号は onMdastAllChapters で spine 順に採番する。素の h1 が複数章にわたる場合でも 正しく連番になる。
  • @kappan/plugin-figure-numbering と併用し図表番号にも章番号を反映させたい場合は、各章 h1 に章番号を明記する(例 # 第3章 タイトル)。素の h1 を本プラグインで自動採番した場合、 figure-numbering 側は章番号を 1 とみなすことがある。
