extracting a function/class/method from code

[Skaperen]

i'm not sure how to look for this. i would like a tool that can be given a file (or stdin) with code and the name of a function or class or method which will extract that function or class or method and output it.

For what purpose?

Are you looking for inspect.getsource() ?

Are you looking for inspect.getsource() ?

almost. if the code i want to extract from can be imported as a module, this could work. for stdin i'd have to copy it to a file, first, unless there is a way to import from stdin or a list of str or a big str.

For what purpose?

to extract source code of a function or class to the end of that function or class, comiing from a file or stdin. this is to find the end of that function or class. maybe parsing indentation (after disposing of comments) would be the easy way.

Are you saying that your functions/classes are so big that it's difficult to find where they end? If so, refactor to make them simpler - it sounds like there's a lot going on in these things which makes them difficult to understand. Clean Code has good advice on the sorts of things you want to go for.

If that's not what you mean, please clarify.

Also, what kind of editor/IDE are you using? They tend to at least let you collapse (and expand) blocks and should be able to show you where the ends are. Note that most of my experience is with using IntelliJ for Java/Scala/Kotlin, but I assume that the tooling is there for Python in other editors.

Still, I strongly suggest refactoring these large things.

they are big relative to code extracting source code. i cannot refactor the whole code. i must extract the functions and classes, first.

Also, what kind of editor/IDE are you using?

emacs/bash within a nearly full screen xterm (i use the same for C and everything else).

refactoring each function/class makes more sense once they are isolated from each other.
