OmniMarkupPreviewer で目次を表示する

Markdown の原稿で目次が出せたらいいなとおもって調べてたら以下の記事に出会った。

SublimeText2でMarkdownにTOCを挿入する

SublimeTextで使ってたのは OmniMarkupPreviewer だったからこれでも拡張できるのかも？？とおもったので設定ファイルを眺めてみた。

Preferences > Package Settings > OmniMarkupPreviewer > Setting - Default

で開く設定ファイルのなかに

ってかんじで、「,"toc"」を追加してみた。

Table of Contents Extension — Python Markdown

をみてみると、

[TOC]

と記述すると目次が出来るみたいなので、それを .md のファイルに入れてみたら目次が出た。
なんと便利なんでしょ。

目次を出す階層を指定出来たりするといいんだろうけど、これでひとまず十分。

仕様書とか、テキストだけだとキツイかもしれないけど、1箇所に集中してまとめとくとかするときはこれでもいいなぁ。
