Turn lines of stdin into JSON.
An example bit of output:
▶ ls -l | tail -n1
-rw-rw-r-- 1 tom tom 1365 Nov 2 14:20 main.go
By default each line becomes an item in an array:
▶ ls -l | tail -n1 | tojson
[
"-rw-rw-r-- 1 tom tom 1365 Nov 2 14:20 main.go"
]
You can use --format=2d-array to split the fields on each line:
▶ ls -l | tail -n1 | tojson --format=2d-array
[
[
"-rw-rw-r--",
"1",
"tom",
"tom",
"1365",
"Nov",
"2",
"14:20",
"main.go"
]
]
Or you can use --format=map and specify the name of each field:
▶ ls -l | tail -n1 | tojson --format=map mode links users group size month day time name
[
{
"day": "2",
"group": "tom",
"links": "1",
"mode": "-rw-rw-r--",
"month": "Nov",
"name": "main.go",
"size": "1365",
"time": "14:20",
"users": "tom"
}
]
