65cb33ec01This implements the ver_replacing command, as proposed for EAPI 9:
| Takes an operator and a version string as arguments, which follow
| the same specification as in ver_test. Iterates over the elements
| of REPLACING_VERSIONS, using ver_test to compare each element with
| the version string. Returns shell true (0) if the specified relation
| is fulfilled for any element. Note that if REPLACING_VERSIONS is
| empty, shell false (1) is returned. The command is only meaningful
| in phases where \t{REPLACING_VERSIONS} is defined.

# @BLURB: Testing implementation of EAPI 9 ver_replacing
|
|
# @DESCRIPTION:
|
|
# A stand-alone implementation of the ver_replacing function aimed
|
|
# for EAPI 9. Intended to be used for wider testing of the proposed
|
|
# function and to allow ebuilds to switch to the new model early, with
|
|
# minimal change needed for the actual EAPI 9.
|
|
#
|

# @CODE
|
|
# if ver_replacing -lt 1.2; then
|
|
# elog "The frobnicate command was dropped in version 1.2"

# fi

# @FUNCTION: ver_replacing

# @USAGE: <op> <ver>

|
# @RETURN: 0 if any element of REPLACING_VERSIONS qualifies, 1 otherwise
|
|
# @DESCRIPTION:
|
|
# Compare each element <v> of REPLACING_VERSIONS with version <ver>
|
|
# using ver_test(). Return 0 (true) if any element <v> fulfills
|
|
# "ver_test <v> <op> <ver>", 1 (false) otherwise.
|
|
#
|
|
# Note: If REPLACING_VERSIONS is empty, 1 (false) is returned.
