A complex multi-file change, with debugging

This is a chat transcript of a fairly complex code change. The user is trying to update tests to use an input mock provided by prompt_toolkit. This requires changes to multiple source files.

Some things to notice:

  • The initial changes don’t work, so the user provides error messages and snippets from the prompt_toolkit docs to collaboratively debug and solve the problem.
  • The user edits a file outside the chat using their editor. PairPilot notices these out-of-band changes and offers to commit them.
  • At one point the user hits ^C to interrupt the LLM response, since it’s not a useful response. The user gives clarifications and gets a better result on the next reply.

instead of using /dev/null to send no input in the main tests, can we use the prompt_toolkit input mocking functions?

Yes, we can use the prompt_toolkit.input module to mock the input in the tests. Here’s how to modify the tests/test_main.py file:

tests/test_main.py
<<<<<<< ORIGINAL
import os
import sys
import tempfile
from unittest import TestCase
from PairPilot.main import main
import subprocess
=======
import os
import tempfile
from unittest import TestCase
from PairPilot.main import main
import subprocess
from prompt_toolkit.input import create_pipe_input
from prompt_toolkit.output import DummyOutput
>>>>>>> UPDATED

Now, update the tests to use the create_pipe_input and DummyOutput:

tests/test_main.py
<<<<<<< ORIGINAL
            with open(os.devnull, "r") as dev_null:
                save_stdin = sys.stdin
                sys.stdin = dev_null
                main([])
                sys.stdin = save_stdin
=======
            pipe_input = create_pipe_input()
            save_stdin = sys.stdin
            sys.stdin = pipe_input
            main([], input=pipe_input, output=DummyOutput())
            sys.stdin = save_stdin
            pipe_input.close()
>>>>>>> UPDATED

            with open(os.devnull, "r") as dev_null:

                sys.stdin = dev_null
                main(["foo.txt"])
                sys.stdin = save_stdin
                self.assertTrue(os.path.exists("foo.txt"))
=======
            pipe_input = create_pipe_input()
            save_stdin = sys.stdin
            sys.stdin = pipe_input
            main(["foo.txt"], input=pipe_input, output=DummyOutput())
            sys.stdin = save_stdin
            pipe_input.close()
            self.assertTrue(os.path.exists("foo.txt"))
>>>>>>> UPDATED

                main(["--yes", "foo.txt"])
                sys.stdin = save_stdin

            main(["--yes", "foo.txt"], input=pipe_input, output=DummyOutput())
            sys.stdin = save_stdin
            pipe_input.close()

These changes will replace the usage of /dev/null with prompt_toolkit’s input mocking functions.

I am getting this error: FAILED tests/test_main.py::TestMain::test_main_with_empty_git_dir_new_file - TypeError: main() got an unexpected keyword argument ‘input’

I apologize for the confusion. It seems I made a mistake in the main() function definition in PairPilot/main.py. The main() function should accept input and output keyword arguments. Here’s the fix:

PairPilot/main.py
<<<<<<< ORIGINAL
def main(args=None):
    if args is None:
        args = sys.argv[1:]
=======
def main(args=None, input=None, output=None):
    if args is None:
        args = sys.argv[1:]
    if input is None:
        input = sys.stdin
    if output is None:
        output = sys.stdout
>>>>>>> UPDATED

Now, the main() function will accept the input and output keyword arguments, and the tests should pass.

Commit 79dfba9 PairPilot: Fixed main() function to accept input and output keyword arguments.

we need to pass those into InputOutput and to prompt_toolkit right?

Yes, you’re right. We need to pass the input and output arguments to the InputOutput class and then to the prompt_toolkit.prompt() function. Here’s how to modify the PairPilot/getinput.py and PairPilot/main.py files:

In PairPilot/getinput.py, update the InputOutput class to accept input and output arguments:

PairPilot/getinput.py
<<<<<<< ORIGINAL
class InputOutput:
    def __init__(self, pretty, yes, input_history_file, chat_history_file):
=======
class InputOutput:
    def __init__(self, pretty, yes, input_history_file, chat_history_file, input=None, output=None):
        self.input = input
        self.output = output
>>>>>>> UPDATED

Now, update the prompt() function calls in the get_input() method to use the input and output arguments:

PairPilot/getinput.py
<<<<<<< ORIGINAL
            line = prompt(
                show,
                completer=completer_instance,
                history=FileHistory(self.input_history_file),
                style=style,
                reserve_space_for_menu=4,
                complete_style=CompleteStyle.MULTI_COLUMN,
            )
=======
            line = prompt(
                show,
                completer=completer_instance,
                history=FileHistory(self.input_history_file),
                style=style,
                reserve_space_for_menu=4,
                complete_style=CompleteStyle.MULTI_COLUMN,
                input=self.input,
                output=self.output,
            )
>>>>>>> UPDATED

In PairPilot/main.py, pass the input and output arguments to the InputOutput class:

PairPilot/main.py
<<<<<<< ORIGINAL
    io = InputOutput(args.pretty, args.yes, args.input_history_file, args.chat_history_file)
=======
    io = InputOutput(args.pretty, args.yes, args.input_history_file, args.chat_history_file, input=input, output=output)
>>>>>>> UPDATED

These changes will ensure that the input and output arguments are passed to the InputOutput class and then to the prompt_toolkit.prompt() function.

I apologize for the confusion. It seems I made a mistake in the prompt_toolkit.prompt() function call. The prompt() function accepts stdin and stdout arguments instead of input and output. Here’s the fix:

Update the prompt() function call in the get_input() method in PairPilot/getinput.py:

            output=self.output,
=======
            stdin=self.input,

>>>>>>> UPDATED

These changes will ensure that the input and output arguments are passed correctly to the prompt_toolkit.prompt() function.

I apologize for the confusion earlier. It seems that the prompt_toolkit.prompt() function does not accept stdin and stdout arguments directly. Instead, we need to use the Application class from prompt_toolkit to create a custom application with the desired input and output. Here’s how to modify the PairPilot/getinput.py file:

First, import the necessary classes and functions from `prompt_tool

^C KeyboardInterrupt

class prompt_toolkit.shortcuts.PromptSession(message: AnyFormattedText = ‘’, *, multiline: FilterOrBool = False, wrap_lines: FilterOrBool = True, is_password: FilterOrBool = False, vi_mode: bool = False, editing_mode: EditingMode = <EditingMode.EMACS: ‘EMACS’>, complete_while_typing: FilterOrBool = True, validate_while_typing: FilterOrBool = True, enable_history_search: FilterOrBool = False, search_ignore_case: FilterOrBool = False, lexer: Lexer | None = None, enable_system_prompt: FilterOrBool = False, enable_suspend: FilterOrBool = False, enable_open_in_editor: FilterOrBool = False, validator: Validator | None = None, completer: Completer | None = None, complete_in_thread: bool = False, reserve_space_for_menu: int = 8, complete_style: CompleteStyle = <CompleteStyle.COLUMN: ‘COLUMN’>, auto_suggest: AutoSuggest | None = None, style: BaseStyle | None = None, style_transformation: StyleTransformation | None = None, swap_light_and_dark_colors: FilterOrBool = False, color_depth: ColorDepth | None = None, cursor: AnyCursorShapeConfig = None, include_default_pygments_style: FilterOrBool = True, history: History | None = None, clipboard: Clipboard | None = None, prompt_continuation: PromptContinuationText | None = None, rprompt: AnyFormattedText = None, bottom_toolbar: AnyFormattedText = None, mouse_support: FilterOrBool = False, input_processors: list[Processor] | None = None, placeholder: AnyFormattedText | None = None, key_bindings: KeyBindingsBase | None = None, erase_when_done: bool = False, tempfile_suffix: str | Callable[[], str] | None = ‘.txt’, tempfile: str | Callable[[], str] | None = None, refresh_interval: float = 0, input: Input | None = None, output: Output | None = None)

Thank you for providing the PromptSession class information. We can use the PromptSession class to create a custom session with the desired input and output. Here’s how to modify the PairPilot/getinput.py file:

First, import the PromptSession class from prompt_toolkit.shortcuts:

PairPilot/getinput.py
<<<<<<< ORIGINAL
from prompt_toolkit import prompt
=======
from prompt_toolkit.shortcuts import PromptSession
>>>>>>> UPDATED

Now, update the get_input() method to use the PromptSession class:

                reserve_space_for_menu=4,
                complete_style=CompleteStyle.MULTI_COLUMN,
                input=self.input,
                output=self.output,
            )

            session = PromptSession(

                completer=completer_instance,
                history=FileHistory(self.input_history_file),

try using create_input(StringIO(‘’)) in the tests

I understand that you want to use create_input(StringIO('')) in the tests. However, I need more information about which test cases you want to apply this change to and how you want to use it. Please provide more details or examples.

the ones that currently use create_pipe_input()

I see that you want to replace create_pipe_input() with create_input(StringIO('')) in the test cases. Here are the changes for the tests/test_main.py file:
