Installation

Get started with Vale, a syntax-aware linter for prose built with speed and extensibility in mind.

Package Managers #

In general, the recommended approach on all platforms is to use a package manager such as Homebrew (macOS) or Chocolatey (Windows):

choco install vale

brew install vale

This will ensure that Vale is available on your $PATH and allow you to stay up to date with new releases.

Vale can also be found at a number of other package repositories. Many of these are community-maintained, so please read the package’s documentation before installing.

GitHub Releases #

Archives of precompiled binaries are available for Windows, macOS, and Linux. To use one of these, you’ll need to download the archive for your platform, extract it to a local directory, and (optionally) add the extracted directory to your $PATH.

An example of this process for Linux is given below:

wget https://github.com/errata-ai/vale/releases/download/v2.28.0/vale_2.28.0_Linux_64-bit.tar.gz
mkdir bin && tar -xvzf vale_2.28.0_Linux_64-bit.tar.gz -C bin
export PATH=./bin:"$PATH"

Docker #

Vale is available on Docker Hub at jdkato/vale:

docker pull jdkato/vale

Vale requires three components: a .vale.ini config file, a StylesPath directory (specified in the config file), and a document or directory to lint.

Here’s an example of calling Vale with locally-defined components (assuming $(pwd)/fixtures/styles/demo contains a config file):

docker run --rm -v $(pwd)/styles:/styles \
           --rm -v $(pwd)/fixtures/styles/demo:/docs \
           -w /docs \
           jdkato/vale .

By default, the image supports HTML, Markdown, AsciiDoc, and reStructuredText content. If you need support for DITA as well, you’ll need to add the relevant dependencies—for example,

# Choose a version to pin:
FROM jdkato/vale:v2.15.2

# Copy a local installation of the DITA Open Toolkit:
COPY bin/dita-ot-3.6 /
ENV PATH="/dita-ot-3.6/bin:$PATH"

ENTRYPOINT ["/bin/vale"]
