Container subclass to generate part of my LaTeX report

I have a LaTeX project which consist of many .tex files. I want to use PyLaTeX to only generate one of these files, so I basically DON’T want PyLaTeX to create the Document etc.

I want something that works like this:

from pylatex.base_classes.containers import Container

class GeneralContainer(Container):
    _latex_name = 'generalcontainer'
    def __init__(self):
        super().__init__()
        
    def dumps(self):
        s = ''
        for child in self:
            if isinstance(child, str):
                s_ = child
            else:
                s_ = child.dumps()
            s+=s_
        return s

Usage: Fill the container with PyLaTeX objects and then save this to a plain .tex file

content= Text()
content.append(...)
content.generate_tex('file.tex')

And than I can use this content in whichever way I want in LaTeX

\section{Section bla bla bla}
\input{file}

Basically I need this kind of general container which is already a subclass of Container, does such one exist? Is this a desired use case for PyLaTeX?

I just released 1.4.0 with the Fragment class included.

You can probably use the Fragment class that this PR introduces: https://github.com/JelteF/PyLaTeX/pull/292
