Running Go from the command line nested JSON

I can think of workarounds on how to get this working however I'm interested in finding out if there's a solution to this specific problem.

I've got a go program which requires a json string arguement:

go run main.go "{ \"field\" : \"value\" }"

No problems so far. However, am I able to run from the command line if one of the json values is another json string?

go run main.go "{ \"json-string\" : \"{\"nestedfield\" : \"nestedvalue\"}\" }"

It would seem that adding escape characters incorrectly matches up the opening and closing quotes. Am I minuderstanding how this is done or is it (and this is the side I'm coming down on) simply not possible?

To reiterate, this is a question that has piqued my curiosity - I'm aware of alternative approaches - I'm hoping for input related to this specific problem.

Why don't you just put your json config to the file and provide config file name to your application using flag package

Based on the feedback from wiredeye I went down the argument route instead. I've modified the program to run on:

go run main.go field:value field2:value json-string:"{\"nestedfield\":nestedvalue}"

I can then iterate over the os.Args and get the nested json within my program. I'm not using flags directly as I don't know the amount of inputs into the program which would have required me to use duplicate flags (not supported) or parse the flag to a collection (doesn't seem to be supported).

Thanks wiredeye
