Ungron to ignore lines saying --

[marcus-downing]

Grep can search for lines immediately preceding or following the matched line, using grep -A, grep -B or grep -C. However the output of these includes separator lines that read --. This output currently produces an error when you try to ungron the result.

Since grep is a primary use for gron, I believe it would be a useful enhancement for it to accept a common output of grep. It doesn't need to do anything with the lines, only match and exclude them.

For example:

$ gron file.json | grep -A 1 'ktoe per year'

json.resources.geothermal.production.units = "ktoe per year";
json.resources.geothermal.production.value = 2007.738525390625;
--
json.resources.hydropower.production.units = "ktoe per year";
json.resources.hydropower.production.value = 9038.80078125;
--
json.resources.wind.production.units = "ktoe per year";
json.resources.wind.production.value = 381.5000305175781;

Sounds like a good call to me!

It's workaround-able with a grep -v '^--' before the ungron, but it seems like it'd be a common enough occurrence to be worthwhile implementing.

I'll have a look at implementing it this evening, unless someone beats me to it of course :)

Thanks for the suggestion!

@marcusatbang sorry it took so long!

Version 0.3.2 should now not have this problem :)

[marcus-downing]

That was remarkably fast. Well done.

[marcus-downing]

Confirmed as working.

Fantastic! Glad to hear it :)
