Is there any plan to support basic markdown?

[existe-deja]

Hi,

I was wondering if it could be possible to support basic markdown like bold underline and italic to prevent translations to be polluted by too much interpolations?

Probably, if you use markdown, you need to combine a parser like markdown-it with the Vue component.
At that time, I think that using Component interpolation can make your request come true.

By combine a parser you think about creating a custom formater or putting markdown content inside my translations and directly inject it by a v-html attribute?
For now I use component interpolation or I prevent the design team to add too much styles for text contents.

@kazupon could you clarify your last post please?

I also think that it could be very convenient to have a way to easily add <strong>, <em> and other simple tags to our texts without having to use component interpolations which are quite cumbersome for these use cases.

99% of the component interpolations in my website are just there to add a <strong> tag around some keyword in the translation text. And so everytime I have at least 5 lines of code in templates and 2 lines in the translation JSONs for what seems to need just one each for a repetitive and trivial use case like this.

<i18n-t keypath="my-simple-text" tag="span">
  <template #strongKeyWorld>
    <strong>{{ $t('strong-keyword') }}</strong>
  </template>
</i18n-t>
…
i18n: {
  my-simple-text: 'This is a {strongKeyWorld} text.',
  strong-keyword: 'simple'
}

To get simply this:

This is a simple text.

Seems overkill.

Would be awesome to be able to write it somehow like this:

{{ $tmd('my-simple-text') }}
…
i18n: {
  my-simple-text: 'This is a **simple** text.'
}

Even if it is not markdown. Something like {{ $tsomething('text', { bold: {…}, italic, etc }) }} would be already helping a lot.

There are multiple ways to make an API that will solve this problem.

Option 1: using a map with vnodes (does not look ugly, supports named placeholders)

<template>
  <Translate keypath="my-message" tag="label" :nodes="nodes" />
</template>

<i18n>
{
  "my-message": "This is my <strong>message</strong>. And you can click this <link>text</link>"
}
</i18n>

<output>
  <label>
    This is my <strong>message</strong>. And you can click this <a href="https://vuejs.org">text</a>
  </label>
</output>

<script lang="ts">
import { defineComponent, h } from '@vue/runtime-core'
import { VNode } from 'vue'

export default defineComponent({
  setup() {
    const nodes: Record<string, VNode> = {
      link: h('a', { href: 'https://vuejs.org' }),
      strong: h('strong'),
    }

    return { nodes }
  },
})
</script>

Option 2: using each named slots single vnode (looks ugly, supports named placeholders)

<template>
  <Translate keypath="my-message" tag="label">
    <template #strong>
      <strong />
    </template>
    <template #link>
      <a href="https://vuejs.org" />
    </template>
  </Translate>
</template>

<i18n>
{
  "my-message": "This is my <strong>message</strong>. And you can click this <link>text</link>"
}
</i18n>

<output>
  <label>
    This is my <strong>message</strong>. And you can click this <a href="https://vuejs.org">text</a>
  </label>
</output>

Option 3: using default slot vnodes (looks nice but no named placeholders)

<template>
  <Translate keypath="my-message" tag="label">
    <strong />
    <a href="https://vuejs.org" />
  </Translate>
</template>

<i18n>
{
  "my-message": "This is my <0>message</0>. And you can click this <1>text</1>"
}
</i18n>

<output>
  <label>
    This is my <strong>message</strong>. And you can click this <a href="https://vuejs.org">text</a>
  </label>
</output>

Option 4: looks better but is impossible because of how slots work

<template>
  <Translate keypath="my-message" tag="label">
    <strong #strong />
    <a #link href="https://vuejs.org" />
  </Translate>
</template>

<i18n>
{
  "my-message": "This is my <strong>message</strong>. And you can click this <link>text</link>"
}
</i18n>

<output>
  <label>
    This is my <strong>message</strong>. And you can click this <a href="https://vuejs.org">text</a>
  </label>
</output>

• All the option should allow to use not only DOM VNodes, but also more complex components. e.g.
• None of the options should by default convert common basic nodes (h1, p) because it adds complexity. Let the developer map correct nodes

const FancyLink = defineComponent({ /* ... */ })
const nodes: Record<string, VNode> = {
  link: h(FancyLink, { href: 'https://vuejs.org' }),
  strong: h('strong'),
}

One can use basic interpolation to replace all simple placeholders ({msg}) then put it through this component that will replace element placeholders (<a>)

Maybe I will look soon into this feature request
