Multi-Language Output

Write one resume file with content in multiple languages. Tag text with {lang=xx} and Resumx generates a separate output for each language, just like tailored variants, but for languages.

## [Experience]{lang=en} [Expérience]{lang=fr}

### Google

- [Reduced API latency by 60%]{lang=en}
  [Réduction de la latence API de 60%]{lang=fr}
- React, Node.js, PostgreSQL, Redis, Docker

That produces two PDFs. Content without {lang=...} appears in both:

en

## Experience

### Google

- Reduced API latency by 60%
- React, Node.js, PostgreSQL, Redis, Docker

fr

## Expérience

### Google

- Réduction de la latence API de 60%
- React, Node.js, PostgreSQL, Redis, Docker

Why lang attribute, not a class like {.lang:en}?

Unlike tags, lang is a standard HTML global attribute. Resumx uses it directly so the output is valid, accessible HTML.

Tagging Content

The lang attribute works everywhere attributes work in Resumx — bracketed spans, element attributes, and fenced divs. Bracketed spans handle most cases:

## [Experience]{lang=en} [Expérience professionnelle]{lang=fr}

### Google

- Reduced API latency by 60% {lang=en}
- Réduction de la latence API de 60% {lang=fr}
- React, Node.js, PostgreSQL, Redis, Docker

For large blocks where everything differs, use fenced divs:

::: {lang=fr}
- Moyenne cumulative : 3.82
- Cours avancés : Systèmes distribués, Algorithmes
:::

Combining with Tags

{lang=xx} and {.@name} work independently. Here, [text]{lang=en} and [text]{lang=fr} each scope to their span, while {.@backend} without brackets is an element attribute that applies to the whole bullet.

- [Designed REST APIs with OpenAPI spec]{lang=en} [Conception d'API REST avec OpenAPI]{lang=fr} {.@backend}

Break into multiple lines for readability — Markdown collapses them into the same bullet:

- [Designed REST APIs with OpenAPI spec]{lang=en}
  [Conception d'API REST avec OpenAPI]{lang=fr}
  {.@backend}

With separate bullets, each is its own element, so both need the tag:

- Designed REST APIs with OpenAPI spec {lang=en .@backend}
- Conception d'API REST avec OpenAPI {lang=fr .@backend}

Language Tags

Values in {lang=xx} are BCP 47 language tags — the same standard used by the HTML lang attribute:

Tag	Language
en	English
fr	French
fr-CA	French (Canada)
de	German
es	Spanish
zh-TW	Chinese (Traditional, Taiwan)
zh-CN	Chinese (Simplified, China)
ja	Japanese
ko	Korean
pt-BR	Portuguese (Brazil)
ar	Arabic

By default, Resumx discovers all {lang=xx} values in your content and generates a separate output for each. Use the --lang CLI flag to limit which languages get generated:

resumx render resume.md --lang en        # English only
resumx render resume.md --lang en,fr     # English and French

Languages combine with tags and formats. For example, 2 langs × 2 tags = 4 PDFs. Each dimension is included in the filename only when it has multiple values: resume-frontend-en.pdf, resume-backend-fr.pdf, etc.
