Contributing

All contributions are appreciated! Please email (no, I'm not busy!) me at akashmozumdar@gmail.com if you have any questions about the codebase.
You should use the standard process of making a pull request (fork, branch, commit changes, make PR from your branch to my master).

Compiling

Before compiling Textractor, you should get Visual Studio with CMake support, as well as Qt version 5.11
You should then be able to simply open the folder in Visual Studio, and build. Run Textractor.exe.

Project Architecture

The host (see GUI/host folder) injects vnrhook.dll (created from the vnrhook folder) into the target process and connects to it via 2 pipe files.
Host writes to hostPipe, vnrhook writes to hookPipe.
vnrhook waits for the pipe to be connected, then injects a few instructions into any text outputting functions (e.g. TextOut, GetGlyphOutline) that cause their input to be sent through the pipe.
Additional information about hooks is shared through a file view (a.k.a. section object) that is mapped to a reference to the TextHook class.
The text that the host receives through the pipe is then processed a little before being dispatched back to the GUI and displayed.
