Heythere ;D
Big JavaScript noob here,
I am currently trying to write an function which can read KeyValue from an KeyName in an settings.file.

Ive tried to do it like that:


function getSettings(keyname) {
    // Read the settings file.
    const textInFile = ccbReadFileContent("settings.gpf");
    //print(textInFile)
    // Split all lines and put them into a list.
    const linesInFile = textInFile.split("\n");
    // Loop trough all lines and find the line with the matching KeyName.
    for (let i = 0; i < linesInFile.length; i++) {
        // Current selected line
        const lineWithIndex = linesInFile[i];
        // If the line matches the KeyName, return to the value of 1 line below.
        if( lineWithIndex === "["+keyname+"]" ) {
            return linesInFile[i + 1];
        }
    }
}

The settings file would look like this:
[ApplicationTitle]
GameXY
[ApplicationVersion]
0.3

So if you want to get the games title, you would need to getSettings("ApplicationTitle");

But the function allways returns 0, i dont know why.

Thanks for any help or tips :D

There is emty space at the end of your string thats why it never == with string you compare..

One way for doing it

function getSettings(keyname) {
const textInFile = ccbReadFileContent("settings.gpf");
const linesInFile = textInFile.split("\n");
for (let i = 0; i < linesInFile.length; i++) {
const lineWithIndex = linesInFile[i];
//print("|"+lineWithIndex.slice(0, -1)+"|");//VISUAL
if( lineWithIndex.slice(0, -1) === "["+keyname+"]" ) {
return linesInFile[i + 1];
}
}
return "NoMatch";
}

Another way


function getSettings(keyname) {
const textInFile = ccbReadFileContent("settings.gpf");
const linesInFile = textInFile.split("\n");
for (let i = 0; i < linesInFile.length; i++) {
const lineWithIndex = linesInFile[i];
if( lineWithIndex === "["+keyname+"]"+"\r" ) {
return linesInFile[i + 1];
}
}
return "NoMatch";
}
