This is a plugin for the nu shell to manipulate strings representing versions that conform to the SemVer specification.
You can compile from source by checking out this repository and running cargo install --path ., or installing the latest version with cargo install nu_plugin_semver.
In both cases you then need to register the plugin by running plugin add /path/to/nu_plugin_semver from within nu. Typically, the plugin can be found in $HOME/.cargo/bin/.
# Parse a semver string into a semver value
> let v = "1.2.3-alpha.1+build" | into semver
# You can access individual fields of a version:
> $v.minor
2
# You can bump a version to different levels:
> $v | semver bump patch
1.2.3+build
> $v | semver bump major
2.0.0
# Semver values can be turned back into strings using
> $v | to text
# Semver values can be matched against a version requirement:
> let v = "3.2.1" | into semver
> $v | semver match-req "3"
true
> $v | semver match-req ">=2"
true
> $v | semver match-req ">=2,<3"
false
# Semver values can be sorted, according to semver semantics
