Ultimately, this is going to require scripting/programming at some level. I am assuming there would be no way to really link these processes, and so maybe there would also need to be a time delay in when the Notepad++ file updates to allow enough time for the WSL executable to finish, and then undergo this process again? The Notepad++ file must then know WHAT parameters to update, how much to increase the time step, how to rename the new directory (maybe through some '++').When the executable has finished, it automatically runs again with the updated Notepad++ file.I suppose the method would have to go such as:

So I am wondering is there a method to automate this? I am currently interested in creating a moving gif for a couple of hundred of this simulation images, and obviously it goes without saying that it would be very time consuming to manually edit the Notepad++ code (time parameter, creating/naming a new directory for the simulation files to save in, etc) every time the executable has completed. To edit parameters (namely how long I want the simulation to run) for this executable I use Notepad++. Under the hood, the app utilizes C++, Lua, and Qt5 for its user interface.I am currently working in WSL with a code that simulates something via an executable in the WSL window.

The developer recommends against it if you need it for critically important work. That being said, Notepad Next is usable and stable for the most part. Note that you should not expect the same level of offering, considering Notepad Next is still under active development (at version 0.5 as of now) and needs several improvements. Notepad Next aims to resemble the feature offerings and the user interface you get with Notepad++. Notepad Next: Open-Source Notepad++ Alternative

Moreover, it is a cross-platform offering. While we do have some options for Notepad++ alternatives, I came across something that tries to re-implement what Notepad++ offers for Linux users. An unofficial Snap package is available to install, but it may not be satisfactory considering it depends on an embedded version of Wine under the hood. Unfortunately, it is not available for Linux users. It is a powerful utility that provides the best possible performance without taking a lot of storage space. Notepad++ is a popular source code editor and a solid Notepad alternative for Windows users. Brief: Notepad Next is an interesting replacement for Notepad++ users on Linux, along with its cross-platform support.
