Increment the patch in a version number

I have a YAML file with semantic versioning number like this:

version: 1.0.1

I need to increment PATCH part of the version. Is it possible to do it with yq?

UPDATE: The question is about mikefarah/yq implementation which is installed with brew install yq.

Solution

  • Please clarify which implementation of yq you are using. Apart from that, the general approach would be to split the string at the dots, convert the last item to a number and increment it, and then rejoin the array with dots.

    Here's one way of doing it using the kislyuk/yq implementation:

    .version |= (./"." | last |= tonumber + 1 | join("."))

    And here's the same using the mikefarah/yq implementation:

    .version |= (split(".") | .[-1] |= ((. tag = "!!int") + 1) | join("."))
