| I'm trying to make a pattern to match variations on prompts in Achaea/Lusternia. I've got it matching and even capturing values if I have all of them displayed in my prompt (health, mana, endurance, and willpower), but I want something that matches on other prompt configurations, also. Variations would include:
100h, 100m ex-
100h, 100m, 100e ex-
100h, 100m, 100w ex-
100h, 100m, 100e, 100w ex-
I know how to match them all in a singular regular expression. Since Lua doesn't implement the full syntax, I was wondering if anyone might be able to find a way to match them with Lua's pattern matching method.
Here's what I have so far:
_,_,health,mana,endurance,willpower,flags = string.find(prompt, "^(%d+)h, (%d+)m, (%d+)e, (%d+)w ([cexkdb@-]+)")

| | I'm not sure if this is the most elegant, but you could check for a non-match (by comparing the first return value to nil) and if the first doesn't match, try the second, then the third, and so forth. |

| Here's basically what I ended up doing. Thanks for the idea!
function OnPluginPartialLine(msg)
_,_,health,mana,flags = string.find(msg, "^(%d+)h, (%d+)m.* ([cexkdb@]+)\-")
if health and mana then
Execute("acp_health " .. health)
Execute("acp_mana " .. mana)
_,_,endurance = string.find(msg, ", (%d+)e")
if endurance then
Execute("acp_endurance " .. endurance)
end
_,_,willpower = string.find(msg, ", (%d+)w")
if willpower then
Execute("acp_willpower " .. willpower)
end
end
if flags then
_,_,cloak,eq,bal,kola,deaf,blind,phase = string.find(flags, "(c?)(e?)(x?)(k?)(d?)(b?)(@?)")
if eq == "" then
Execute("acp_balance eq false")
else
Execute("acp_balance eq true")
end
if bal == "" then
Execute("acp_balance bal false")
else
Execute("acp_balance bal true")
end
if cloak == "" then
Execute("acp_undef cloak")
else
Execute("acp_ondef cloak")
end
if kola == "" then
Execute("acp_undef kola")
else
Execute("acp_ondef kola")
end
if deaf == "" then
Execute("acp_undef deafness")
else
Execute("acp_ondef deafness")
end
if blind == "" then
Execute("acp_undef blindness")
else
Execute("acp_ondef blindness")
end
if phase == "" then
Execute("acp_undef phase")
else
Execute("acp_ondef phase")
end
end
end
