Merge several files using v4

[luisR2]

Hi,

I was using the v3 version to merge several yaml files (inside the folder configFiles) into one combined file using this commad:

yq m -a=append ./configFiles/*.yml > ./newConfig/combined.yml

Now I'm trying to get the same result with v4 but I'm not getting the same combined file. The command that I'm using is:

yq eval-all 'select(fileIndex == 0) * select(filename == ".yml")' ./configFiles/.yml > ./newConfig/combined.yml

Which would be the equivalent v4 command as the previous v3 that I was using?

Thanks!

This should do it:

Thanks for the answer, I tried the "*+" but didnt' work. The idea is to merge f2.yml not into f1.yml but in a new created yml (https://mikefarah.gitbook.io/yq/commands/evaluate-all) like it was done in the pass with:
yq merge -a=true /path/to/yaml/files

I mean maybe it can't be done anymore in this new v4 version?

Ah ok - this looks like it's related to this enhancement request: #674 - just need to figure out how to actually implement it (and get the time to do it :S )

Hey you are right, that request is exactly what I need. Well it will be great if that is implemented someday. I will then remain in v3 until this feature is released

Thanks so much!

You can now do this in 4.6.0:

https://mikefarah.gitbook.io/yq/operators/reduce#merge-all-yaml-files-together

[itoffshore]

this works well for merging nodes together (extra +):

yq eval-all '. as $item ireduce ({}; . *+ $item )' file.yaml file2.yml

Looking forward to check this new version, thanks for notifying! El jue, 18 feb 2021 a las 9:44, Mike Farah (<[email protected]>) escribió:
