gron.awk
Similar to tomnomnom/gron but in Awk.
Features true JSON parser in pure Awk.
Reasonably fast with Gawk/Mawk/GoAWK even on large-ish files. Slow with BWK on big JSON files (100K+).
Developed in xonixx/intellij-awk. Incubated from xonixx/awk_lab.
Usage
Gron:
$ echo '{"a":[1,2,3]}' | ./gron.awk
json={}
json.a=[]
json.a[0]=1
json.a[1]=2
json.a[2]=3
Un-Gron:
$ echo '{"a":[1,2,3]}' | ./gron.awk | ./gron.awk - -u
{
"a": [
1,
2,
3
]
}
Filter part of JSON:
$ curl -s "https://api.github.com/repos/xonixx/gron.awk/commits?per_page=1" \
| ./gron.awk | grep "commit.author" | ./gron.awk - -u
[
{
"commit": {
"author": {
"date": "2021-10-19T11:31:34Z",
"email": "xonixx@gmail.com",
"name": "xonix"
}
}
}
]
$ curl -s 'https://ip-ranges.amazonaws.com/ip-ranges.json' | ./gron.awk - -s
