I have vague recollections of a tool that was similarly supposed to make JSON files diffable. IIRC it procedurally built up the object, so {"foo": {"bar": "baz", "quux": [1, 2, 3]}} would be:
foo = {}
foo.bar = "baz"
foo.baz = []
foo.baz[0] = 1
... $ augtool -r . --noautoload --transform "Json.lns incl /sirdb-example.json" <<EOF
> print /files/sirdb-example.json/
> EOF
/files/sirdb-example.json
/files/sirdb-example.json/dict
/files/sirdb-example.json/dict/entry[1] = "_owner"
/files/sirdb-example.json/dict/entry[1]/string = "nouser"
/files/sirdb-example.json/dict/entry[2] = "username"
/files/sirdb-example.json/dict/entry[2]/string = "nouser"
/files/sirdb-example.json/dict/entry[3] = "email"
.... etc ...What's up with requiring "--noautoload"? What does "-r ." do? and the transform invocation starts with the seemingly magical "Json.lns" (where does it come from?) and appears to refer to a file at the root of the filesystem hierarchy?
I'd probably use augtool more often myself, but its UI is seriously inscrutable.
I'm writing a little program to make this whole lot easier.
Answers: by default, augtool loads all the lenses and scans the entire default filesystem (typically /etc); `--noautoload` prevents that.
The -r is `--root`; specify the root as the current directory rather than /
