previously setting TERMUX_PKG_UPDATE_VERSION_REGEXP had no effect on version being wriiten to build.sh. It was only used for version comparison. Signed-off-by: Aditya Alok <dev.aditya.alok@gmail.com>

# NOTE: This function returns true even when CURRENT_VERSION = "1.0" and LATEST_VERSION = "1.0-1".
|
|
# This is logically correct, but repology sometimes returns "1.0-1" as the latest version even
|
|
# if "1.0" is latest. This happens when any of the repositories tracked by repology has specified
|
|
# "1.0-1" as the latest.
|
|
#
|
|
# For example:
|
|
# latest lua:lpeg version (as of 2021-11-20T12:21:31) is "1.0.2" but MacPorts specifies as "1.0.2-1".
|
|
# Hence repology returns "1.0.2-1" as the latest.
|
|
#
|
|
# But hopefully, all this can be avoided if TERMUX_PKG_UPDATE_VERSION_REGEXP is set.
