Discuss: Incremental linting beta

[fabio-looker]

LAMS v3.1 will introduce the ability to do incremental linting, marked as beta. This issue will provide a space for people to share their feedback.

I just tried this out, and I can see that it adds exemptions to the lams-exemtions.ndjson file. However, it doesn't seem like these exemptions are automatically removed from the file once the issues are fixed. This means one needs to manually maintain and remove exemptions. I think this is something that could be nice to include.

A bit unrelated but still on the topic of "incremental linting", I can't get the source argument to work as intended. Whenever I try to lint by adding just the files I want to lint (including the manifest, since it's mandatory), like this:

lams --reporting=no --output=lines,markdown --on-parser-error=info --source manifest.lkml file1.lkml file2.lkml

It seems like LAMS completely ignores everything that comes after the first file (in this case, manifest.lkml) because it always outputs 0 matches, 0 matches exempt, and 0 errors

Similarly, whenever, the manifest file is not the first file in the list of arguments, it claims it cannot find the manifest file.

Hi @jolfad ! Thanks for taking the time to provide some feedback!

Pruning the unused exemptions is a great suggestion, I'll plan on adding that functionality.

As for the source argument, it should be a single string value, which will be passed to the glob npm module. So, like --output="**/{*.model,*.explore,*.view,manifest}.lkml". Perhaps your suggestion would be the more "CLI convention following" way to accept these arguments, which I should also support...
