p7d-markdown-it-strong-ja

This is a plugin for markdown-it. It is an alternative to the standard ** (strong) and * (em) processing. It also processes strings that cannot be converted by the standard.

Use

import mdit from 'markdown-it'
import mditStrongJa from '@peaceroad/markdown-it-strong-ja'
import mditAttrs from 'markdown-it-attrs'
const md = mdit().use(mditStrongJa).use(mditAttrs)

md.render('HTMLは**「HyperText Markup Language」**の略です。')
// <p>HTMLは<strong>「HyperText Markup Language」</strong>の略です。</p>


md.render('HTMLは*「HyperText Markup Language」*の略です。')
// <p>HTMLは<em>「HyperText Markup Language」</em>の略です。</p>

Notice. Basically, it is assumed that you will use markdown-it-attrs in conjunction with this. If you do not use it, please use use(mditStrongJa, {mditAttrs: false}).

Example

The following examples is for strong. The process for em is roughly the same.

Options

disallowMixed

When disallowMixed: true, emphasis is blocked in English contexts that contain markdown links, HTML tags, inline code, or math expressions to maintain better compatibility with standard markdown-it behavior.

const md = mdit.use(mditStrongJa)
md.render('string**[text](url)**')
// <p>string<strong><a href="url">text</a></strong></p>

const md = mdit.use(mditStrongJa, { disallowMixed: true })
md.render('string**[text](url)**')
// <p>string**<a href="url">text</a>**</p>

coreRulesBeforePostprocess

strong_ja_postprocess runs inside the markdown-it core pipeline. When other plugins register core rules, you can keep their rules ahead of strong_ja_postprocess by listing them in coreRulesBeforePostprocess. Each name is normalized, deduplicated, and re-ordered once during plugin setup.

const md = mdit()
  .use(cjkBreaks)
  .use(mditStrongJa, {
    coreRulesBeforePostprocess: ['cjk_breaks', 'my_custom_rule']
  })

• Default: []
• Specify ['cjk_breaks'] (or other rule names) when you rely on plugins such as @peaceroad/markdown-it-cjk-breaks-mod and need them to run first.
• Pass an empty array if you do not want mditStrongJa to reorder any core rules.
