startswith, endswith throwing "invalid input text" error when trying to use with select about yq HOT 3 OPEN

Thanks for raising; note that my yq is not a wrapper around jq; but rather tries to re-implement it in go (so you don't need jq or python to run it).

The reason you're getting that error is because I haven't yet added that operator in :)

You can still get what you want by either using the match operator:

echo '{"ppl":[{"name":"alice"},{"name":"bob"},{"name":"charlie"},{"name":"deb"}]}'  | yq '.ppl[] | select(.name | match(".*b"))'

Or wildcards:

echo '{"ppl":[{"name":"alice"},{"name":"bob"},{"name":"charlie"},{"name":"deb"}]}'  | yq '.ppl[] | select(.name == "*b")'

from yq.

Also, happy to take PRs for adding startswith / endswith :)

from yq.

Ah, I guess I'd put something in the lexer/parser or whatever that if it sees something that looks like a function, but isn't recognized, an error that it's an unknown function or not defined rather than "invalid input text"

$ echo {} | jq ".thing | select(.whatever)"  # runs fine (no output)
$ echo {} | jq ".thing | asdf(.whatever)"
jq: error: asdf/1 is not defined at <top-level>, line 1:
.thing | asdf(.whatever)
jq: 1 compile error

from yq.
