USER: where in the repo is the /add command handled?

ASSISTANT: The `/add` command is handled in the `aider/commands.py` file. However, this file is currently read-only. If you want to make changes to this file, please add it to the chat.

USER: I added these *read-write* files: aider/commands.py

USER: replace this algorithm:     def completions_add(self, partial):

        files = files - set(self.coder.get_inchat_relative_files())

                yield Completion(fname, start_position=-len(partial))              by an algorithm that checks that the characters in partial.lower() exists in the same order in fname.lower(), i.e. asdf/foo would exist in that order in the fname.lower='aaasssdddfff///fffoooooo'

ASSISTANT: To implement this change, we need to modify the `completions_add` method in the `aider/commands.py` file. Here is the change:

<source>python
aider/commands.py
<<<<<<< HEAD
    def completions_add(self, partial):
        files = set(self.coder.get_all_relative_files())
        files = files - set(self.coder.get_inchat_relative_files())

                yield Completion(fname, start_position=-len(partial))
>>>>>>> updated
</source>

In the updated code, we first convert both `partial` and `fname` to lowercase. Then we check if all characters in `partial` exist in `fname` and if the characters in `partial` appear in the same order in `fname`. If both conditions are met, we yield the completion.

# Aider chat conversation:

USER: there is no need to calculate `partial_lower = partial.lower()` each time in the loop.

ASSISTANT: You're correct. We can optimize the code by calculating `partial_lower` outside the loop. Here is the change:

    def completions_add(self, partial):
        files = set(self.coder.get_all_relative_files())
        files = files - set(self.coder.get_inchat_relative_files())
        for fname in files:
            partial_lower = partial.lower()
            fname_lower = fname.lower()
            if all(c in fname_lower for c in partial_lower) and \
               ''.join(c for c in fname_lower if c in partial_lower) == partial_lower:
                yield Completion(fname, start_position=-len(partial))
=======
    def completions_add(self, partial):
        files = set(self.coder.get_all_relative_files())
        files = files - set(self.coder.get_inchat_relative_files())
        partial_lower = partial.lower()
        for fname in files:
            fname_lower = fname.lower()
            if all(c in fname_lower for c in partial_lower) and \
               ''.join(c for c in fname_lower if c in partial_lower) == partial_lower:
                yield Completion(fname, start_position=-len(partial))

ASSISTANT: To add a mocked `Coder` instance in the `setUp` method of the `TestCommandCompletions` class in `tests/test_command_completions.py`, we need to modify the `setUp` method. Here is the *edit block* for this change:

USER: how can I run the tests in test_command_completions?

ASSISTANT: To run the tests in `test_command_completions.py`, you can use the `unittest` module from the command line. Navigate to the directory containing the `tests` folder and run the following command:

```bash
python -m unittest tests.test_command_completions
```

This command will discover and run all the test methods in the `TestCommandCompletions` class in the `test_command_completions.py` file. The `-m` flag tells Python to run the `unittest` module as a script, and `tests

ASSISTANT: The test `test_completions_add` is failing because the result of the `completions_add` method is an empty list, while the expected result is `['a/b/c/d', 'a/b/c/e', 'a/b/c/f']`.

The `completions_add` method in `aider/command_completions.py` is responsible for generating the completions. It seems like the method is not finding any matches for the partial string "a/b" in the list of all relative files.

Let's modify the `completions_add` method to debug the issue. We will print the `files` and `partial_lower` variables to understand why no matches are found.

Here is the *edit block* for this change:

```python

            if all(c in fname_lower for c in partial_lower) and \
               ''.join(c for c in fname_lower if c in partial_lower) == partial_lower:

        files = files - set(self.coder.get_inchat_relative_files())
        partial_lower = partial.lower()
        print(f"Files: {files}")
        print(f"Partial: {partial_lower}")
        for fname in files:
            fname_lower = fname.lower()
            if all(c in fname_lower for c in partial_lower) and \

                yield Completion(fname, start_position=-len(partial))

After making this change, run the tests again and check the output of the print statements. This will help us understand why the `completions_add` method is not finding any matches for the partial string "a/b".

# Aider chat conversation:

USER: use partial="ab/c"

ASSISTANT: To use `partial="ab/c"` in the test, we need to modify the `test_completions_add` method in the `tests/test_command_completions.py` file.

Here is the change:

The `completions_add` method is designed to match the partial string with the filenames in a case-insensitive manner. It does this by checking if all characters in the partial string
^C KeyboardInterrupt

USER: fix the completions_add functions so that for example partial=ab/c would match a file a/b/c.  it should check that the characters in partial should exist in the filename, *in the exact same order*, but the matching characters do not need to be adjacent.

ASSISTANT: To fix the `completions_add` function, we need to modify the condition that checks if the partial string matches the filename. Currently, it checks if all characters in the partial string exist in the filename and if they appear in the same order. However, it doesn't account for the fact that the matching characters do not need to be adjacent.

We can fix this by using a different approach to check for a match. Instead of checking if all characters in the partial string exist in the filename, we can iterate over both the partial string and the filename at the same time and check if the characters match. If they do, we move to the next character in both strings. If they don't, we only move to the next character in the filename. If we reach the end of the partial string, it means we have found a match.

Here is the step-by-step explanation of the changes:

1. Add a new test case in the `test_completions_add` method.
2. Set `partial = "aabb"`.
3. Call the `completions_add` method with the new `partial` and collect the `text` attribute of the returned `Completion` objects in a list.
4. Sort the resulting list.
5. Set the `expected` list to `['aa/bb/cc/dd']`.
6. Compare the `result` list to the `expected` list.

Here is the *edit block* for the change:

  python3 -m unittest tests.test_command_completions

And got this output:

..
----------------------------------------------------------------------
Ran 2 tests in 0.000s

OK
Files: {'a/b/c/d', 'a/b/c/f', 'aa/bb/cc/dd', 'a/b/c/e'}
Partial: ab/c
Files: {'a/b/c/d', 'a/b/c/f', 'aa/bb/cc/dd', 'a/b/c/e'}
Partial: aabb

ASSISTANT: Great! It seems like your tests are passing successfully. The output shows that all the tests ran without any failures or errors. The "Files" and "Partial" lines are print statements from your `completions_add` method in the `CommandCompletions` class. They are showing the set of files and the partial string that the method is working with for each test case. Is there anything else you would like to do or any other questions you have?

USER: in test_completions_drop add a test where partial=a/b/c/d and the expected returned result should be a/b/c/d

ASSISTANT: To add a new test case to the `test_completions_drop` method, we need to modify the `tests/test_command_completions.py` file.

Here are the steps:
1. Add a new test case in the `test_completions_drop` method where `partial` is "a/b/c/d".
2. Call the `completions_drop` method with the new `partial` and store the result.
3. The expected result should be a list containing "a/b/c/d".
4. Use the `assertEqual` method to compare the result with the expected result.

Here is the *edit block* for the changes:

```python
tests/test_command_completions.py
<<<<<<< HEAD
    def test_completions_drop(self):
        partial = "a/b"
        result = list(self.command_completions.completions_drop(partial))
        expected = []
        self.assertEqual(result, expected)
=======
    def test_completions_drop(self):
        partial = "a/b"
        result = list(self.command_completions.completions_drop(partial))
        expected = []
        self.assertEqual(result, expected)

        partial = "a/b/c/d"
        result = list(self.command_completions.completions_drop(partial))
        expected = ["a/b/c/d"]
        self.assertEqual(result, expected)

```

Please apply this change and let me know if you have any questions.

USER: remove print statements from aider/command_completions.py

USER: update get_command_completions so that getattr etc is run on self.command_completions, not on self.

ASSISTANT: To update the `get_command_completions` method in the `Commands` class of the `aider/commands.py` file, we need to modify the `getattr` function to be run on `self.command_completions` instead of `self`.

This is what I'm trying to accomplish here... for a repo with a deeper hierarchy it is more convenient to not have to write all intermediate characters.

part of the reason for pulling the completions into a separate class is that otherwise gpt4-8k will rate-limit. the aider/commands.py file is too big already to be conveniently used with gpt4-8k.

Thanks for putting together this PR. I am unfamiliar with this style of autocompletion? Is it used by other shells/tools/etc?

I think there are quite a few styles for completion, for example in emacs you have flex-style matching as documented in mastering emacs, and called orderless-flex in https://github.com/oantolin/orderless#component-matching-styles

My goal was simply to type less, but I guess it should be possible to also "stack" completion resolution algorithms on top of each other and use the original one first and then this one, stripping duplicates. This way only more options would be visible, but prefix matches would always be preferred.

I like this idea, I did expect some kind of partial match, and I find myself doing a lot of tabbing because I don't wish to type the entire path. I do wonder if explicit wildcard characters would be of similar quality experience and easier to work with.

Edit: I must have been doing it wrong because that feature already landed: #57
