HDATravel quirk with new god Pakellas

[mkflynn]

Pakellas does not regenerate MP upon rest, so this needs to be added to HDAtravel.rc:

line 47:
: local you_are_pak = string.find(you.god(), "Pakellas")

changes to line ~170:
elseif you_are_pak then : autoexplore() : else rest() : end

The solution I came up with for my rc file was to change the should_rest function to be this:
function should_rest(hp, mp, max_hp, max_mp)
local you_are_mummy = string.find(you.race(), "Mummy")
local you_are_deep_dwarf = string.find(you.race(), "Deep Dwarf")
local you_are_pak = string.find(you.god(), "Pakellas")
return (not you_are_pak and mp < (max_mp_0.50) or ((max_mp-mp) > 20)
or ((hp < (max_hp_0.80)) or ((max_hp-hp) > 30)
and not you_are_deep_dwarf)
or you.slowed()
or you.poisoned()
or you.confused()
or you.exhausted()
or (((hp < max_hp) or (mp < max_mp)) and you_are_mummy))
end
