escape chars about jq HOT 10 CLOSED

@theoreticaLee you can use keys with slashes, but you'll have to use explicit strings as the keys:

jq '.slash/key' won't work, but jq '.["slash/key"]' will.
jq '{slash/key}' won't work, but jq '{"slash/key"}' will.

from jq.

You can use the following syntax:

jq '.feed.entry[] | {"group": .["media$group"]}'

The {foo} syntax is shorthand for this, but you need to use the longhand version if there are unusual characters in the field name.

from jq.

Now (if you build master) you can use:

jq '.feed.entry[] | {"media$group"}'

from jq.

honestly love that one : just so useful today, using hashicorp vault api...

None of the above solutions worked, I had to generate a jqparams.txt file using a "heredoc" and put environment variables in it, then pass that using jq --from-file jqparams.txt.

Would be nice to see this program play better with bash primitives.

For what it's worth, to access a sub-element where the sub-key has a slash:
jq '.devDependencies."@angular/cli"' package.json

from jq.

Along the same lines - I'm getting errors when the keys I'm trying to query for have '.' or ':' in them - ie/ 'foo.bar.baz:8008' is a key I'm trying to pull out out some JSON.

ok, thanks for your answer

Yeah, it would be great to add in escaping ability. I'm running into trouble with facebook's api as some results have keys with forward slash in them :/

@Jean-Baptiste-Lasselle I'm dealing with the same thing, in the list of accessors at sys/auth
