Hello, I took this Java code from your blog. I just have one question. Why are the lines and columns not printed in my EditText when the code has an error in the for loop?

Please leave a repo with the issue you mentioned.

This is my main problem, bro. When I want to analyze my JavaScript code, I want to get the line and column if I encounter an error and use it in my editor.

Please set a breakpoint and look inside. I don't understand why you want to add integer 'line' and integer 'column'.

Because I am developing my own IDE, I want to know when my code has errors so that I can give the line and column to my code. For example, see the following link https://github.com/HanzoDev1375/Ghostide/blob/main/app/src/main/java/io/github/rosemoe/sora/langs/javascript/BasicSyntaxJavaScriptAnalyzer.java#L64 I don't like my code parser to be with antlr4. I am looking for a powerful parser. Please help me.

Did you really understand my question? it.getSpan().getLine()+ it.getSpan().getColumn() only gives you one integer.

Honey, that's for the token. Did you see my code?

I don't think you are showing enough respect.

I don't think you are showing enough respect.

I think you misunderstood what I meant. I need a feature to parse the code. If my code gives an error, I can display the error text and the line and column.
like this
error file in Main.js:1:40
So I need to get the line and column and apply it in my program so that a red wavy line is drawn under the word so that my user understands. We are now sending a sample image that works with the antlr4 parser.
