Command line tool to modify YAML files

[Alex Breadman]

Hi everyone,

I needed a tool today to insert or overwrite top-level values in a YAML file so that my CI pipeline can be cleaner and less complicated.

So I made a Go cmd tool called:

https://github.com/golangdaddy/yamlfukr

I hope someone finds this useful! I will be making a Github Action once I figure out how.

Please contribute where you think improvements can be made.

If written because you needed experience and writing a program to perform a task you need done is better for learning, then go you! But if you are legitimately looking to solve a problem, you might want to throw a quick search out first before implementing Yet Another X.

For yamlfukr update file.yaml key value:

https://github.com/mikefarah/yq

yq w -i file.yaml key value

yq also supports b.c.d.e key names to edit deeper values.

https://github.com/TomWright/dasel

dasel put string -f file.yaml -p yaml "key" value

dasel also supports b.c.d.e key names to edit deeper values.

https://github.com/grasmash/yaml-cli

yaml-cli update:value file.yml key value  

If you intend to keep developing yamlfukr, you might want to examine some of the alternatives, and if you find them unsuitable, add to your documentation why you find them so, so that someone coming on your project can see why they should consider going with your tool instead of one of the alternatives.

Thanks for the reply.

I just did it for fun actually, and for the purpose of learning to make GitHub actions.

I saw yq but it seemed like it was written in python, which I have no time for.

The dasel one looks the best imo.

You're going to be limiting your tooling options quite a bit in that case :)

Not really.

I'll just rewrite them in go if there isn't a tool I need, or it the interface is crappy. I have built a few databases from scratch, so writing simple tools is trivial.
