Flat is a command line tool to flatten json and yaml structures
I wrote this tool a while ago when dealing with a great deal of databags for Chef which are basically json files, I wanted look inside those files and grep for a specify path, I could not do it, I would need to flatten the structure before I could grep.
It also helps me a lot when writting kubernetes, helm charts and cloudformation files.
We can install it with Homebrew
brew tap tlopo-ruby/flat
brew install flat
Or as standalone executable script:
curl -sL https://raw.githubusercontent.com/tlopo-ruby/flat/master/flat.rb > /usr/local/bin/flat
chmod +x /usr/local/bin/flat
Flattening using the default separator |:
$ curl https://postman-echo.com/get -s | flat
args = {}
headers | x-forwarded-proto = https
headers | host = postman-echo.com
headers | accept = */*
headers | user-agent = curl/7.54.0
headers | x-forwarded-port = 443
url = https://postman-echo.com/get
Flattening specifying . as separator:
$ curl https://postman-echo.com/get -s | flat -s .
args = {}
headers.x-forwarded-proto = https
headers.host = postman-echo.com
headers.accept = */*
headers.user-agent = curl/7.54.0
headers.x-forwarded-port = 443
url = https://postman-echo.com/get
