The grammar of Semantic Versioning 2.0.0. It accepts the same strings as the suggested regular expression of semver.org, with ASCII classes and a whole-string match:

text

version        = core [ "-" pre-release ] [ "+" build ]
core           = number "." number "." number
number         = "0" / ( %x31-39 *DIGIT )                 ; no leading zeros
pre-release    = pre-id *( "." pre-id )
pre-id         = number / alnum-id
build          = build-id *( "." build-id )
build-id       = 1*( DIGIT / ALPHA / "-" )
alnum-id       = *DIGIT ( ALPHA / "-" ) *( DIGIT / ALPHA / "-" )

There is no v prefix: v1.2.3 does not pass. Leading zeros are rejected in the version numbers and in numeric pre-release identifiers (1.2.3-01), but allowed in build metadata (1.2.3+001).
