All markdown files skipped when I make unrelated changes to skip pattern

I’m running under macOS, with these versions:

$ nvm current
v16.13.0
$ npm --version
8.4.0
$ npm ls linkinator                                                                 
opentelemetry-specification@ /Users/chalin/git/lf/open-telemetry/opentelemetry-specification
└── linkinator@3.0.3

I’m using linkinator to check markdown files in a repo, something like this:

$ npx linkinator '**/*.md' --markdown --skip '^https|node_modules' --verbosity error
🏊‍♂️ crawling **/*.md
[0] http://localhost:9411/api/v2/spans%22
specification/sdk-environment-variables.md
  [0] http://localhost:9411/api/v2/spans%22
ERROR: Detected 1 broken links. Scanned 137 links in 6.076 seconds.

That works great.

Now, I’d like to skip all links starting with either http or https so I add ? to the skip regex:

$ npx linkinator '**/*.md' --markdown --skip '^https?|node_modules' --verbosity error
🏊‍♂️ crawling **/*.md
🤖 Successfully scanned 0 links in 0.186 seconds.

If I use verbosity info I see that it is now skipping all files. Why? Is there something I’m missing?

It’ll skip all files even when I try with these regexs:

• http|https|node_modules
• http|https
• https?

Thanks!

Hi @danieleds. This is value I ended up using for the skip parameter:

• ^http://localhost:9411|/node_modules/|^https://github\\.com/some-org/some-project/(issues|pull)

I hope that this helps.

Specifically, I’m trying to skip all

* external links

* explicit links to `http://localhost`

@chalin did you find how to do this?
