# @BLURB: Testing implementation of EAPI 7 version manipulators
|
||||
# @DESCRIPTION:
|
||||
# A stand-alone implementation of the version manipulation functions
|
||||
# aimed for EAPI 7. Intended to be used for wider testing of
|
||||
# the proposed functions and to allow ebuilds to switch to the new
|
||||
# model early, with minimal change needed for actual EAPI 7.
|
||||
#
|
||||
# https://bugs.gentoo.org/482170
|
||||
#
|
||||
# @SUBSECTION Version strings
|
||||
#
|
||||
# The functions support arbitrary version strings consisting of version
|
||||
# components interspersed with (possibly empty) version separators.
|
||||
#
|
||||
# A version component can either consist purely of digits ([0-9]+)
|
||||
# or purely of uppercase and lowercase letters ([A-Za-z]+). A version
|
||||
# separator is either a string of any other characters ([^A-Za-z0-9]+),
|
||||
# or it occurs at the transition between a sequence of letters
|
||||
# and a sequence of digits, or vice versa. In the latter case,
|
||||
# the version separator is an empty string.
|
||||
#
|
||||
# The version is processed left-to-right, and each successive component
|
||||
# is assigned numbers starting with 1. The components are either split
|
||||
# on version separators or on boundaries between digits and letters
|
||||
# (in which case the separator between the components is empty).
|
||||
# Version separators are assigned numbers starting with 1 for
|
||||
# the separator between 1st and 2nd components. As a special case,
|
||||
# if the version string starts with a separator, it is assigned index 0.
|
||||
#
|
||||
# Examples:
|
||||
#
|
||||
# @CODE
|
||||
# 1.2b-alpha4 -> 1 . 2 '' b - alpha '' 4
|
||||
# c s c s c s c s c
|
||||
# 1 1 2 2 3 3 4 4 5
|
||||
#
|
||||
# .11. -> . 11 .
|
||||
# s c s
|
||||
# 0 1 1
|
||||
# @CODE
|
||||
#
|
||||
# @SUBSECTION Ranges
|
||||
#
|
||||
# A range can be specified as 'm' for m-th version component, 'm-'
|
||||
# for all components starting with m-th or 'm-n' for components starting
|
||||
# at m-th and ending at n-th (inclusive). If the range spans outside
|
||||
# the version string, it is truncated silently.

# Simple Example 1: $PV is 1.2.3b, we want 1_2.3b:

# selected.
