I am writing in C++ and during long contests I feel more comfortable to create a project for the given task. Nevertheless, at the end I am supposed to submit a single file. I am curios if you use some tools that digest the project to a file?
In Emacs you could open the same file in different buffers and use narrow-to-region on different parts of the file. That also works well with the Codingame Sync extension, because it’s still just one file. It only looks like you have multiple files open.
At the moment when i code in C++ it’s all in one file. I should take the time to create a makefile for that.
