Vale Server's extensibility and flexibility isn't just limited to creating English rules—most of its features are largely language-agnostic, allowing for entire styles to be created in other languages.
A few of Vale's extension points were designed to specifically work for English and therefore can't be easily extended to other languages:
readability: This extension point relies on formulas that are specifically designed to work on English text.
capitalization: This extension point involves changing the case of headings to match English style guides.
sequence: This extension point depends on a natural language processing library that currently only supports English.
English By Default
The following extension points require that non-English rules specify
nonword: true in order to disable the use of default word boundaries (
extends: existence message: 'Avoid using "%s"' nonword: true # <-- This is required level: suggestion tokens: - '根据'
spelling extension point requires the user to provide their own Hunspell-compatible dictionary.
