In Less is safer: Reducing the risk of supply chain attacks
viraptor·Feb 8, 2024
This makes me happy. I've just done a review of yaml parsers available from Ruby recently to improve the error reporting. Unfortunately libyaml is just bad there - many indentation issues at the end of the document will report errors in line 2 with a completely lost context. Unfortunately x2, there's no real alternative. I ended up parsing with libyaml and when something fails, parsing again using node and displaying errors through https://github.com/eemeli/yaml It's terrible but it works better. I hope to be able to use libyaml-safer in the future if it does improve on errors. Also, having found an asserting case for libyaml in the past, I'm not trusting it that much.
