# ported to WeeChat (http://www.weechat.org/) by Nils Görs.

# 2026-09-05: 1.2.3 TehPeGaSuS <pegasus@computer4u.com>
# : fix: memoryusage() showed free memory mislabeled as used, and
# the percentage could go negative, because the used/free values
# were swapped in the final display/percent calculation
# 2026-09-05: 1.2.2 TehPeGaSuS <pegasus@computer4u.com>
# : fix: memory usage broken (uninitialized values / division by 0,
# closes #581) on kernel >= 6.x due to kernel version regex only
