Modify get_input() to accumulate input lines between { and } and return the concatenated lines with '\n'.

# Context:
USER: modify get_input(). if the user inputs a line with just { then keep accumulating input lines until you receive a line with just }. in this case, discard the {} lines and return the rest of the lines concatenated with '\n'
ASSISTANT: To modify the `get_input()` function to accumulate input lines between `{` and `}`, we will change the function to handle this case.

Here's the updated code for the `get_input()` function:

```python
coder.py
<<<<<<< ORIGINAL
    def get_input(self):
        if self.pretty:
            self.console.rule()
        else:
            print()

        inp = ""
        if self.pretty:
            print(Fore.GREEN, end="\r")
        else:
            print()

        while not inp.strip():
            try:
                inp = input("> ")
            except EOFError:
                return

        ###
        if self.pretty:
            print(Style.RESET_ALL)
        else:
            print()

        readline.write_history_file(history_file)
        return inp
=======
    def get_input(self):
        if self.pretty:
            self.console.rule()
        else:
            print()

        inp = ""
        multiline_input = False
        if self.pretty:
            print(Fore.GREEN, end="\r")
        else:
            print()

        while True:
            try:
                line = input("> ")
            except EOFError:
                return

            if line.strip() == "{" and not multiline_input:
                multiline_input = True
                continue
            elif line.strip() == "}" and multiline_input:
                break
            elif multiline_input:
                inp += line + "\n"
            else:
                inp = line
                break

        if self.pretty:
            print(Style.RESET_ALL)
        else:
            print()

        readline.write_history_file(history_file)
        return inp
>>>>>>> UPDATED
```

This change will allow the `get_input()` function to accumulate input lines between `{` and `}` and return the concatenated lines with '\n'.
