Exclude some chars from gui-edit

[DakiLLa]

Hi. I want to prevent users typing in some characters in edit field, such as "[", "]" (square brackets), and "^". How can I do that?

Right now I'm using the next pattern:

string.gsub( someText, '[^A-z, ^0-9]', '' ) 

Thx in advance.

local s = 'Kenix^' 
if s:match( '[%[%^%]]' ) then 
    print 'n' 
else 
    print 'y' 
end 

--> n

You mean it?

I don't need to check wether or not there are special chars in the string. I want to make it fix the string automatically, like 'gsub' does.

local s = 'Kenix^^^[[[]]]' 
print( s:gsub( '[%[%^%]]', '' ) ) 

--> Kenix

Ty.

No problem.

One more question: how to exclude '\' char ?

[Kenix]

local s = 'Kenix\\1' 
print( s ) -- > Kenix\1 
print( s:gsub( '\\', '' ) ) --> Kenix1 

Well if you have string like this it's unfinished string

print( '\' )

P.S \ is hided in bb code.

So if you want use \ char you need:

print( '\\' ) --> \

Ah ye, there was a mistake in my code, so I thought '\\' won't work.

It works now, thanks again.
