I have a command for a bot I work on that's as follows :
.command @user @user2 (user list can grow etc..) item
The current regex I am using is
/([.command]+ [@A-Za-z0-9_?]+ [A-Za-z0-9]+)/g
The problem I have is that I need it to find each user instead of only the first occurrence. Ideally I'd also like to be able to target that each user starts with a "@" character.
Any help on this appreciated.
Use
/^\.([a-z]+)\s+((?:@[\w?]+\s+)+)(\w+)/i
Capture group 1 is the command.
Capture group 2 will contain all the @user parameters, you can use .split(/\s+/) to split it into separate users.
Capture group 3 is the item at the end
This is one (of many) solution:
function getUsers(command){
var result = [];
var index = command.indexOf("@");
while(index>-1){
var i1 = command.indexOf("@", index);
var i2 = command.indexOf(" ", i1);
if(i2==-1){i2 = command.length;}
var user = command.substr(i1, i2-i1);
index = command.indexOf("@", i2);
result.push(user);
}
return result;
}
getUsers("cmd @a1 @a2 @a3 ckkasd @a5 a6 @a7")
This one dont uses regular expressions. It will consume less memory and will run faster for big strings.
