Question

In my properties file that I have for a mod I’m making for Minecraft I will need to have my properties file recognized certain words as being variables. These words will be contained like so: {variable name}

Here is an example of what might need to be parsed:

command01 = /ban {user} g {reason}  //This is read into the variable command1 only taking the things after the equals sign

{user} would be defined in an input box in the GUI. {reason} would also be as well.

{User} would equal the variable user which would be a String
{Reason} would equal the variable input1 which would be a String as well

Lets say the variable user holds the string “Fogest” and the input1 variable holds the string “He did xyz wrong”.

I essentially need to retrieve that value from the GUI which is already done, and then replace {User} and {Reason} with what those variables are equal to in the GUI.

After all my rambling the question is how would I go about parsing the string command1 to find placeholders such as {user} and {reason} and replace them with what the corresponding variable holds.

I hope this isn’t to confusing. If it just mention it in the comments and I will try and rephrase it.

Answer 1

It looks like what you question boils down to is some kind of string substitution. I think what you’re looking for is something like this

String someString = "We went to the {location}.";
System.out.println(someString.replace("{location}", "store"));

Running this code produces

We went to the store.
