Typora自動(dòng)編號(hào)的具體操作

相比較world這種文檔編輯器而言，Typora更適合寫一些程序相關(guān)的博客，因?yàn)榭梢杂么a+快捷鍵的方式，方便的對(duì)文章內(nèi)容進(jìn)行處理，不用在擔(dān)心排版和樣式變形的問(wèn)題了，在編輯的過(guò)程中，就能預(yù)覽到效果

概述

在使用Typora寫比較長(zhǎng)的文章時(shí)，需要給章節(jié)編號(hào)，方便區(qū)分層次。如果手動(dòng)編號(hào)，一旦章節(jié)順序改變，很多章節(jié)的編號(hào)都需要一一手動(dòng)修改，極其麻煩。

Typora官方提供了自動(dòng)編號(hào)的方法：https://support.typora.io/Auto-Numbering/。本文將對(duì)官方提供的方法，以及簡(jiǎn)單改進(jìn)進(jìn)行介紹。

原理

這個(gè)方法的原理是，Typora基于瀏覽器開發(fā)（使用快捷鍵Shift+F12可以打開開發(fā)者工具）。因此，可以利用CSS實(shí)現(xiàn)自動(dòng)編號(hào)。

具體操作

打開Typora -> 文件 -> 偏好設(shè)置 -> 外觀 -> 打開主題文件夾。
在主題文件夾下新建文件base.user.css。
將https://support.typora.io/Auto-Numbering/中提供的三份代碼（分別實(shí)現(xiàn)文章內(nèi)容自動(dòng)編號(hào)、TOC自動(dòng)編號(hào)、側(cè)邊欄大綱自動(dòng)編號(hào)）復(fù)制到base.user.css中。
重啟Typora。

改進(jìn)

官方提供的代碼會(huì)對(duì)一級(jí)標(biāo)題進(jìn)行編號(hào)，但實(shí)際寫文章時(shí)，一級(jí)標(biāo)題往往是文章標(biāo)題，無(wú)需編號(hào)，因此，我對(duì)代碼進(jìn)行了簡(jiǎn)單修改。下面是修改后的代碼：

文章內(nèi)容自動(dòng)編號(hào)：

/** initialize css counter */
h1 {
    counter-reset: h2
}

h2 {
    counter-reset: h3
}

h3 {
    counter-reset: h4
}

h4 {
    counter-reset: h5
}

h5 {
    counter-reset: h6
}

/** put counter result into headings */
#write h2:before {
    counter-increment: h2;
    content: counter(h2) ". "
}

#write h3:before,
h3.md-focus.md-heading:before /** override the default style for focused headings */ {
    counter-increment: h3;
    content: counter(h2) "." counter(h3) ". "
}

#write h4:before,
h4.md-focus.md-heading:before {
    counter-increment: h4;
    content: counter(h2) "." counter(h3) "." counter(h4) ". "
}

#write h5:before,
h5.md-focus.md-heading:before {
    counter-increment: h5;
    content: counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) ". "
}

#write h6:before,
h6.md-focus.md-heading:before {
    counter-increment: h6;
    content: counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) "." counter(h6) ". "
}

/** override the default style for focused headings */
#write>h3.md-focus:before,
#write>h4.md-focus:before,
#write>h5.md-focus:before,
#write>h6.md-focus:before,
h3.md-focus:before,
h4.md-focus:before,
h5.md-focus:before,
h6.md-focus:before {
    color: inherit;
    border: inherit;
    border-radius: inherit;
    position: inherit;
    left:initial;
    float: none;
    top:initial;
    font-size: inherit;
    padding-left: inherit;
    padding-right: inherit;
    vertical-align: inherit;
    font-weight: inherit;
    line-height: inherit;
}

TOC自動(dòng)編號(hào)：

/* No link underlines in TOC */
.md-toc-inner {
    text-decoration: none;
}
 
.md-toc-h1 {
    margin-left: 0;
    font-size: 1.5rem;
    counter-reset: h2toc
}
 
.md-toc-h2 {
    font-size: 1.1rem;
    margin-left: 2rem;
    counter-reset: h3toc
}
 
.md-toc-h3 {
    margin-left: 3rem;
    font-size: .9rem;
    counter-reset: h4toc
}
 
.md-toc-h4 {
    margin-left: 4rem;
    font-size: .85rem;
    counter-reset: h5toc
}
 
.md-toc-h5 {
    margin-left: 5rem;
    font-size: .8rem;
    counter-reset: h6toc
}
 
.md-toc-h6 {
    margin-left: 6rem;
    font-size: .75rem;
}
 
.md-toc-h2:before {
    color: black;
    counter-increment: h2toc;
    content: counter(h2toc) ". "
}
 
.md-toc-h2 .md-toc-inner {
    margin-left: 0;
}
 
.md-toc-h3:before {
    color: black;
    counter-increment: h3toc;
    content: counter(h2toc) ". " counter(h3toc) ". "
}
 
.md-toc-h3 .md-toc-inner {
    margin-left: 0;
}
 
.md-toc-h4:before {
    color: black;
    counter-increment: h4toc;
    content: counter(h2toc) ". " counter(h3toc) ". " counter(h4toc) ". "
}
 
.md-toc-h4 .md-toc-inner {
    margin-left: 0;
}
 
.md-toc-h5:before {
    color: black;
    counter-increment: h5toc;
    content: counter(h2toc) ". " counter(h3toc) ". " counter(h4toc) ". " counter(h5toc) ". "
}
 
.md-toc-h5 .md-toc-inner {
    margin-left: 0;
}
 
.md-toc-h6:before {
    color: black;
    counter-increment: h6toc;
    content: counter(h2toc) ". " counter(h3toc) ". " counter(h4toc) ". " counter(h5toc) ". " counter(h6toc) ". "
}
 
.md-toc-h6 .md-toc-inner {
    margin-left: 0;
}

側(cè)邊欄大綱自動(dòng)編號(hào)：

.outline-h1 {
    counter-reset: h2
}
 
.outline-h2 {
    counter-reset: h3
}
 
.outline-h3 {
    counter-reset: h4
}
 
.outline-h4 {
    counter-reset: h5
}
 
.outline-h5 {
    counter-reset: h6
}
 
.outline-h2>.outline-item>.outline-label:before {
    counter-increment: h2;
    content: counter(h2) ". "
}
 
.outline-h3>.outline-item>.outline-label:before {
    counter-increment: h3;
    content: counter(h2) "." counter(h3) ". "
}
 
.outline-h4>.outline-item>.outline-label:before {
    counter-increment: h4;
    content: counter(h2) "." counter(h3) "." counter(h4) ". "
}
 
.outline-h5>.outline-item>.outline-label:before {
    counter-increment: h5;
    content: counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) ". "
}
 
.outline-h6>.outline-item>.outline-label:before {
    counter-increment: h6;
    content: counter(h2) "." counter(h3) "." counter(h4) "." counter(h5) "." counter(h6) ". "
}
