rewrap | a regexp wrapper , less pain and more fun with regexp | Regex library

Let's assume I copied some comma-separated data from somewhere and want to create a Python list. The data might look like this:

Hope you are doing well!

I'm using a function that is utilizing the lru_cache of functools library. for example:

I'm writing a derive procedural macro where all of the values are converted to Options. The problem is that any Option fields in the struct can be contained within these Option types. On its own, this isn't much of an issue until I start to serialize the data with serde. I want to be able to skip any values where the value is None, but there are cases where it will come out to being something like Some(None) or Some(CustomOption::None). Both of these cases are not any more meaningful than a simple None, but I can't just write #[serde(skip_serializing_if = "Option::is_none")] on the derived fields. Of course, they output a null value in a JSON format though.

Basically, I want to be able to use the syn library to check to see if the type of a derived field's inner value is going to be an Option and flatten it out into a singular Option in the derived struct instead of an Option> type. I wish Rust had type-based pattern matching on the generics but that's not really a thing.

I can think of two solutions to this problem but I can't really think of how to implement them. First one would be to traverse all of the fields and find the Options, then unwrap those options and re-wrap them so that they only have a single Option on the outside. One potential problem with this solution is that I may have to rewrap them in another Option after doing the computations. The second solution would be to find the Option and modify the generated code accordingly so that if the inner option contains None the entire thing becomes None; basically just have a helper function that outputs a boolean if the field is an Option. Any ideas on how to implement either of these or a better solution?

Here's a code example:

I would like to keep just the "inside" lines of a latex table created by kable. I only know cumbersome and ugly ways to do so...attempts at cleaner versions failed. here is one clean flunk:

I have "Wrap on typing" enabled in my PyCharm settings, which works great if I type a new line, but it seems to be quite messy when editing already wrapped code, as it keeps existing line-breaks even if they are superfluous.

I also use Ctrl-Alt-L to auto-format my code, but that doesn't remove unnecessary line breaks either.

Example: Let's say I originally wrote this code in one go, without putting manual line breaks, then PyCharm's "Wrap on typing" wraps it like this:

If std::optional's value() member function is called when the optional has no actual value initialized, a std::bad_optional_access is thrown. As it is derived directly from std::exception, you need either catch (std::bad_optional_access const&) or catch (std::exception const&) for dealing with the exception. However, both options seem sad to me:

• std::exception catches every single exception
• std::bad_optional_access exposes implementation details. Consider the following example:

On a remote machine I am trying to use wget to download extensions for VS Code. However, the downloaded files are always corrupt and cannot be used. It turns out that using wget or curl will retrieve files which are a bit smaller than using a browser, so it appears reasonable that they cannot be unzipped. The URL I have used for downloading is https://marketplace.visualstudio.com/_apis/public/gallery/publishers/stkb/vsextensions/rewrap/1.9.1/vspackage

I'm sorry about this looking like a "trivia" question, but this is the most minimal example I could come up with:

I am making a python script that uses ffmpeg and moviepy to convert videos to mp4. I want to make an if statement that checks if the input file needs to be reencoded or just rewrapped.(if the input file is aac and h.264 it does not need to be reencoded.) Is there a simple way I can grab that file info?
