Bug:

code like:

String s = "\n";
String s= "\"";

println("X" +
"X");

Give compilation errors due to the fact the quotation character is replaced with multiple escaped characters ("\"")

LS4P/server/src/grammer/terms/preprocessingsnippets.ts

Lines 113 to 122 in 1998f6e

export function mapperPipeline(newUnProcessedText: String): string{
let localUnProcessedText = newUnProcessedText.replace(/([0-9]+\.[0-9]+)/g,'$1f')
conversionTuples.forEach(function(tuple){
localUnProcessedText = localUnProcessedText.replace(tuple[0],tuple[1])
})
localUnProcessedText = localUnProcessedText.replace(preprocessing.singleLineComment,``)
// localUnProcessedText = localUnProcessedText.replace(/[\']{1}/g,"\\\'")
localUnProcessedText = localUnProcessedText.replace(/[\"]{1}/g,"\\\"")
return localUnProcessedText
}

Possible Solution

I think the problem lies at the method to create the java file:

LS4P/server/src/parser.ts

Lines 39 to 44 in 1998f6e

try{
childProcess.execSync(`echo \"${processedText}\" > ${__dirname}/compile/${pStandards.defaultClassName}.java`)
log.writeLog(`Java File creation successful`)
} catch(e) {
log.writeLog(`[[ERR]] - Error in Java File Creation`)
}
It now uses an echo command to create the file. If instead a method like fs.writeFileSync() is used there is no need for escaping quotation characters to write the java file. All characters should be written to the file "as is".
