This commit introduces the `--message-file` flag to the `aider` tool, allowing users to specify a file containing the message to send to GPT. This feature processes the reply and then exits, disabling the chat mode. The implementation includes reading the content of the specified file and using it as the prompt message.
Additionally, a unit test has been added to `tests/test_main.py` to ensure the correct functionality of the `--message-file` flag. The test includes necessary mocks to handle non-interactive environments and verifies that the tool behaves as expected when a message file is provided.
This enhancement improves the usability of the `aider` tool for users who prefer or require non-interactive execution, such as in scripting or automated workflows.
# Aider chat conversation:
USER: Am I correct that currently if one wants to launch aider from commandline , the way to go is to use --message flag that allows providing prompt as command line parameter?
ASSISTANT: Yes, you are correct. The `--message` or `-m` flag can be used to provide a single message to send to GPT, process the reply, and then exit the application. This flag disables the interactive chat mode and is suitable for scripting or when you want to issue a single command without entering the interactive chat session.
USER: Is there a way to run prompt from command line like `--message` or `-m` however by providing prompt as file ?
ASSISTANT: Currently, there is no direct command-line option in the `aider` tool to provide a prompt from a file. The `--message` or `-m` flag only accepts a string as an argument. If you want to provide a prompt from a file, you would need to read the content of the file and pass it as a string to the `--message` flag.
However, this functionality can be added to the `aider` tool by implementing a new command-line option that reads the content of a specified file and uses it as the prompt message.
Would you like me to implement this feature for you? If so, please provide the `aider/main.py` file, and I will suggest the necessary changes.
USER: How would you name such flag to match current convention and how would you describe it?
ASSISTANT: Following the current naming convention used in the `aider` tool, a suitable name for the flag that allows providing a prompt from a file could be `--message-file` or `-mf`. This flag would be described as:
"Specify a file containing the message to send to GPT, process the reply, then exit (disables chat mode)."
This description aligns with the existing `--message` flag while clearly indicating that the input is expected to be a file containing the message rather than a direct string input.
USER: could you please add such flag?
ASSISTANT: To add the `--message-file` flag to the `aider` tool, we need to modify the `aider/main.py` file. Please add the `aider/main.py` file to the chat so I can provide you with the necessary changes.

USER: I added these *read-write* files: /home/gw-t490/github/VariousForks/aider-patching-for-pull-requests/aider/main.py
ASSISTANT: Great, now that you've added the `aider/main.py` file, I will provide you with the necessary changes to implement the `--message-file` flag.
We will need to:
1. Add a new command-line argument `--message-file` to the argument parser.
2. Read the content of the file specified by `--message-file` and pass it to the `coder.run()` method.
Here are the *SEARCH/REPLACE* blocks for the changes:

return 1
except IOError as e:
io.tool_error(f"Error reading message file: {e}")

```
These changes will add the `--message-file` flag to the argument parser and handle the case where a message file is provided. If the file is found and can be read, its content will be used as the message to send to GPT. If there is an error reading the file, an error message will be displayed, and the program will exit with a status code of 1.
# Aider chat conversation:
USER: if main != origin/main, explain which one is behind
ASSISTANT: To implement this feature, we need to modify `scripts/versionbump.py`. We will add additional logic to the `check_main_branch_up_to_date` function to compare the commit dates of `main` and `origin/main` and print a message explaining which one is behind.
Here is the *SEARCH/REPLACE* block for the changes:
scripts/versionbump.py
```python
<<<<<<< SEARCH
if local_main != origin_main:
print("Error: The main branch is not up to date with origin/main. Please pull the latest changes.")
sys.exit(1)
=======
if local_main != origin_main:
local_date = subprocess.run(["git", "show", "-s", "--format=%ci", "main"], capture_output=True, text=True).stdout.strip()
origin_date = subprocess.run(["git", "show", "-s", "--format=%ci", "origin/main"], capture_output=True, text=True).stdout.strip()
local_date = datetime.datetime.strptime(local_date, "%Y-%m-%d %H:%M:%S %z")
origin_date = datetime.datetime.strptime(origin_date, "%Y-%m-%d %H:%M:%S %z")
if local_date < origin_date:
print("Error: The local main branch is behind origin/main. Please pull the latest changes.")
elif local_date > origin_date:
print("Error: The origin/main branch is behind the local main branch. Please push your changes.")
else:
print("Error: The main branch and origin/main have diverged.")
sys.exit(1)
>>>>>>> REPLACE
```
Please note that we need to import the `datetime` module at the beginning of the file to use `datetime.datetime.strptime`. Here is the *SEARCH/REPLACE* block for adding the import:
scripts/versionbump.py
```python
<<<<<<< SEARCH
import argparse
import re
import subprocess

```
These changes will compare the commit dates and print a message explaining which branch is behind if they are not in sync.
# Aider chat conversation:
USER: it's printing Error: The main branch is not up to date with origin/main. even though main is up to date with origin/main
ASSISTANT: To address the issue you're experiencing with the script reporting that the main branch is not up to date with `origin/main` even though it is, we should add additional logging to the script to help diagnose the problem. We can print out the commit hashes for `local_main` and `origin_main` before the comparison to see what the script is actually getting from the `git` commands.
Let's modify the `scripts/versionbump.py` file to add this logging.
Here is the *SEARCH/REPLACE* block:
scripts/versionbump.py
```python
<<<<<<< SEARCH
local_main = subprocess.run(["git", "rev-parse", "main"], capture_output=True, text=True).stdout.strip()
origin_main = subprocess.run(["git", "rev-parse", "origin/main"], capture_output=True, text=True).stdout.strip()
if local_main != origin_main:
print("Error: The main branch is not up to date with origin/main.")
=======
local_main = subprocess.run(["git", "rev-parse", "main"], capture_output=True, text=True).stdout.strip()
print(f"Local main commit hash: {local_main}")
origin_main = subprocess.run(["git", "rev-parse", "origin/main"], capture_output=True, text=True).stdout.strip()
print(f"Origin main commit hash: {origin_main}")
if local_main != origin_main:
print("Error: The main branch is not up to date with origin/main. Please pull the latest changes.")
>>>>>>> REPLACE
```
This change will print out the commit hashes for both `local_main` and `origin_main` before the script checks if they are the same. This should help you diagnose why the script thinks the branches are not in sync. If the hashes are indeed the same, but the script still reports an error, it could be an issue with the script's logic or the environment in which it's being run.
# Aider chat conversation:
USER: before changing the repo, check that we are on the main branch, check that the working dir is not dirty, fetch the latest changes from origin and confirm that the main branch is up to date (don't merge it though). if any of these fail, exit with an error.
ASSISTANT: To implement these checks in the `scripts/versionbump.py` file, we will need to add the necessary Git operations before proceeding with the version bumping logic. Here are the steps we will follow:
1. Import the `sys` module to exit the script with an error if needed.
2. Add a function to check the current Git branch and ensure it is 'main'.
3. Add a function to check if the working directory is clean.
4. Add a function to fetch the latest changes from the origin and check if the 'main' branch is up to date.
5. Call these functions at the beginning of the `main()` function.

dry_run = args.dry_run
# Perform checks before proceeding
check_branch()
check_working_directory_clean()
check_main_branch_up_to_date()
>>>>>>> REPLACE
```
These changes will ensure that the script checks for the current branch, the cleanliness of the working directory, and whether the 'main' branch is up to date with the origin before proceeding with the version bumping process. If any of these checks fail, the script will exit with an error message.
