String Patterns

Asked Mar 30, 2014352 views2 answers

I'm really struggling with this.. I'm trying to get only the first 2 per line in the string printed but it doesn't work perfectly

local pattern = "(%w+)%s?(%w+).-%d+"
local get = [[Start	Tackle	Normal	Physical	50	100%	 35
Start	Harden	Normal	Status	?	?%	 30
Start	Headbutt	Normal	Physical	70	100%	 15]]

for level, move in get:gmatch(pattern) do
	print(level.." "..move)
end

Here is my output:

Start Tackle
10 0
Start Harden
Start Headbutt
10 0

It should only be

Start Tackle
Start Harden
Start Headbutt

This is what you need to produce the results you want.

local pattern = "(%w+)%s?(%w+).-\n"
local get = [[Start Tackle  Normal  Physical    50  100%     35
Start Harden  Normal  Status  ?   ?%   30
Start Headbutt    Normal  Physical    70  100%     15
]]

for level, move in get:gmatch(pattern) do
    print(level.." "..move)
end

The output

Start Tackle
Start Harden
Start Headbutt

oh thanks! I didn't know \n could be used in Lua!

the reason it does this is because it has digits to get rid of digits just change the pattern to this

pattern = "(%w+)%s?(%w+)"

if you use the %d then it will also include digits
