Is there a way to print a node to string?

Is there a way to convert a node (e.g. MethodDeclaration) into a string, either pretty-print (aka, reformatting) or print the original code?

I didn’t find such methods in javalang. I had experiences with Roslyn in .net and javaparse. Both support this functionality.

This is very old but this is the solution I came up with for my problem.

    def get_code_snippet (lines, index):
            openingBrackets = 0;
            closingBrackets = 0;

            # Resulting snippet
            snippet = ""

            # loop until we find the final closing bracket, or go over the limit
            while index < len(lines):
                line = lines[index]
                for letter in line:
                    if letter == '}':
                        closingBrackets += 1
                    elif letter == '{':
                        openingBrackets += 1

                    snippet += letter

                    # Early end if we have reached last bracket
                    if closingBrackets == openingBrackets and openingBrackets != 0:
                        return snippet
                    
                index += 1

            return snippet

I called the method in this way:

lines = code.split("\n")
for child in node.body:
    get_code_snippet (lines, child.position[0] - 1)

I hope it can help anyone who stumbles upon this!
