Please do not change output strings about gron

[kseistrup]

This seems to have fixed the issue. Thanks for fixing it so swiftly!

I managed to get a few minutes free to sort this.

The changes are available in v0.6.0.

Please let me know if you hit any more problems!

Hi @kseistrup! Thanks for raising an issue!

It looks like this is actually the default behaviour of Go's encoding/json package (which is used only when the output is not colourised). I'll see about fixing this for you now

[tomnomnom]

@kseistrup this should be fixed in master now. Are you able to update with go get -u github.com/tomnomnom/gron, or would you like me to upload a binary so you can test?

[kseistrup]

I can go get, so I'll try it right away…

While the JSON itself is identical, the new code adds a blank line after the JSON whenever stdout is not a TTY:

$ gron config.json | grep friends
json.friends = {};
json.friends.hops = 3;
$ gron config.json | grep friends | ungron
{
  "friends": {
    "hops": 3
  }
}
$ gron config.json | grep friends | ungron | cat
{
  "friends": {
    "hops": 3
  }
}

In case like me you were wondering what is different about the 2 examples, here is something minimal to illustrate the issue:

$ echo 'json[0] = "&";' | ungron
[
   "&"
]
$ echo 'json[0] = "&";' | ungron | cat
[
  "\u0026"
]

Thanks for the minimal example, @rjmunro.

That issue has been solved, but the JSON outputs are still not identical:

$ echo 'json[0]="&";' | ungron
[
  "&"
]
$ echo 'json[0]="&";' | ungron | cat
[
  "&"
]

Hey; thanks for reminding me about this!

I'll see if I can get a fix in for it soon. Happy to accept PRs for it too ;)

@tomnomnom,

For lists and single elements the indentation is different:

$ echo 3 | gron | ungron
 3
$ echo 3 | gron | ungron | cat
3
$ echo '[1,2,3]' | gron | ungron
[
   1,
   2,
   3
]
$ echo '[1,2,3]' | gron | ungron | cat
[
  1,
  2,
  3
]

Mappings are not affected, though:

$ echo '{"a":true,"b":false}' | gron | ungron
{
  "a": true,
  "b": false
}
$ echo '{"a":true,"b":false}' | gron | ungron | cat
{
  "a": true,
  "b": false
}
$
