Cloudwatch Query Language (pschorrql)

[douglasg14b]

I have read the page on language requests, this is not a language request for the core team.

My intention here is to provide the details for this language that I can pick up when able, or someone else passionate about it can pick up with all the info they need. otherwise I fear it would be lost in the cracks, since it took a bit of work to even figure out what this is called, or what the language definition is.

Here is the language definition from https://github.com/nathanpeck/ecs-patterns-vitepress/blob/2ed8c33740a227e801425ceefc5dd45a4559b2bc/.vitepress/config.ts#L32

This appears to be called pschorrql in the monaco editor in Cloud Watch.

Anyone would be open to run with this as a 3rd party grammar, but it's not really an issue we can leave open - as there is nothing for us to do here. Happy to have the details live in issue history though if that's helpful to anyone.

Yeah mainly the point of the issue was to capture the information so if someone comes searching there should be enough to get them started, and/or when/if I find a few hours to onboard to how to do this I can find the info here again.
