No way to match a pattern that contains * or ?

[preethamrn]

Describe the bug
If a user wants to find all strings which exactly match a pattern, however the pattern contains a * or ?, it will match unwanted entries.

Version of yq: 4.9.3
Operating system: mac
Installed via: homebrew

Input Yaml
data1.yml:

- cat*
- cat*
- cat

Command
The command you ran:

yq eval '.[] | (. == "cat*")' data1.yml # results shown below
yq eval '.[] | (. == "cat\*")' data1.yml # escaping doesn't help
yq eval '.[] | (. == "cat.*")' data1.yml # regex isn't supported
yq eval '.[] | (. === "cat.*")' data1.yml # strict equality operator isn't supported

Actual behavior

true
true
true

Wanted behavior

true
true
false

Additional context
Either supporting regex matching or adding a === operator that does exact matching could fix this.

Yeah good point - I think regex would work well

4.10.0 has new regex operators that can be used for this:

yq e '.[] | test("cat\*")' examples/data1.yaml
