Feature Request: support for regex/glob expressions in the `/add` function

[JPDucky]

Feature Description Currently, the /add function accepts directory paths to add the entire directory or spefic file paths to the program's context. A useful enhancement would be to support the use of regex or glob expressions with the /add function. This would give users more flexibility and control to specify exactly which files to include.

Proposed Solution Allow the /add function to interpret glob or regex patterns. For example, a user could use /add src/*.py to include only Python files from the src directory or /add src/[A-C]* to add only files that start with A, B, or C.

Expected Behavior When a user runs /add with a regex or glob pattern, the program should add to the context only the files that match the pattern. The program should handle non-matching files or non-existent paths gracefully, preferably by ignoring them and printing a warning message.

Alternatives Considered An alternative could be providing an additional function, say /addPattern, that accepts regex/glob patterns. This approach would leave the existing /add functionality unchanged for users who don't need the enhanced functionality.

Additional Context Adding this feature would boost the flexibility of the /add function, making the program more convenient to use for a variety of tasks. Users could, for instance, exclude certain types of files or select a subset of files based on their naming conventions.

Good idea. I've been meaning to do this.

I pasted your issue text into aider and it did most of the heavy lifting on the PR.

[paul-gauthier]

I just merged this change. Thanks again for the suggestion.

You can pick it up by installing the latest version directly from github.

Awesome, can't wait to try this out. It was having issues with a vanilla vuejs project because it creates a logo.png in the assets directory, and I'm sure vue is not the only one that does this by default

So throwing a wildcard at the end works, but it does not add files recursively, only the files in the folder specified. Trying to add just a directory makes the program throw the following and exit:

> /add src/components

Perhaps more robust file handling is needed. I'll be able to dig deeper later this afternoon

I just merged a fix for the error above. /add and /drop now recurse into subdirs.

I'm going to close this issue for now, but feel free to re-open or file a new issue if you have any further problems.
