As Packer is using json for the config, I would like to run a preprocessor 
before running packer to strip Javascript comments from the json file.

I have found a nodejs tool for that called strip-json-comments-cli which 
works ok, but since that requires npm install, it seems like kind of 
complicated to provision e.g. in a CI environment just for the single 
script.

On the other hand I could add the stripped file in the git repo so that as 
long as there are no changes in the source file, the tool is not needed 
(which would solve the CI question).

Can anyone suggest other tools (e.g. in go) or are you using another 
procedure to get comment support for the config file?


Thanks, Alexander
