# tldr-lint

`tldr-lint` is a linting tool for validating [tldr](https://github.com/tldr-pages/tldr) pages.
It can also format your pages for you!
## Installation
`tldr-lint` and its alias `tldrl` can be installed via `npm`:
```sh
npm install --global tldr-lint
```
## Usage
It's really simple.
```txt
Usage: tldr-lint [options]
Options:
-V, --version output the version number
-f, --format also attempt formatting (to stdout, or as specified by -o)
-o, --output output to formatted file
-i, --in-place formats in place
-t, --tabular format errors in a tabular format
-v, --verbose print verbose output
-I, --ignore ignore comma separated tldr-lint error codes (e.g. "TLDR001,TLDR0014")
-h, --help display help for command
```
### Usage via Docker
We provide a Dockerfile for reproducibly building and testing `tldr-lint` even without having NodeJS installed.
For building the Docker image, run this command inside the cloned `tldr-lint` repository:
`docker build -t tldr-lint .`
For running a `tldr-lint` container, you need to mount a volume containing the page(s) you want to lint to the container.
For checking a single page, run (replacing `{{/path/to/page.md}}` with the path to the page you want to check):
`docker run --rm -v {{/path/to/page.md}}:/app/page.md tldr-lint page.md`
In order to run the container on a directory, mount this directory as follows:
`docker run --rm -v {{/path/to/directory}}:/app/pages tldr-lint pages/`
> [!NOTE]
> For Windows users, specify the full path to the directory or page you want to check along with the `docker run` command above.
