These functions allow user you to parse a semantic version string or test it with constraint.

It’s implemented with the https://github.com/Masterminds/semver library.

Returns a semantic version struct holding the input version string.

Usage

semver.CheckConstraint constraint input
input | semver.CheckConstraint constraint

Arguments

name description
constraint (required) The constraints expression to test.
input (required) The input semantic version string to test.

true

$ gomplate -i '{{ semver.CheckConstraint "> 1.0, <1.1" "v1.1.1" }}'
