New linter error if the link in more information isn’t reachable anymore about tldr-lint

[owenvoke]

I think that this shouldn't really be part of the linter. 🤔 Especially as the linter runs every time a new page is added (or a PR is merged), we might be spamming a lot of sites. 😬

Can you explain a bit about how we could implement it in Linter?

Would you ping the page's links to check if it is reachable? Or is there something we can use natively?

We could use wget to do something like this:

LINK_OF_INTEREST=$(awk 'NR==3{print $3}' file.md)
TOTAL_TIME=$(wget --page-requisites --output-document /dev/null "$LINK_OF_INTEREST" 2>&1 | grep -oE 'Total wall clock time: [0-9.]+s' | grep -oE '[0-9.]+')

if [ "$(echo "$TOTAL_TIME < 1" | bc -l)" -eq 1 ]; then
    echo "Total time is below 1 second"
else
    echo "Total time is 1 second or more"
fi

I get that! Maybe we can create a script that run's once a month to report any broken links?

This is exactly what I thought too as we document lesser-known tools too, we might be stressing their servers by sending multiple requests at a time if it got included in the linter.
