Where is the definitition for TMP_TextUtilities.FindIntersectingWord

Hello, I'm trying to become more familiar with event systems and c# in general, and I'm confused about what's happening in "TMP_TextUtilities", which appears to be just a series of lines like

"public static int FindNearestWord(TMP_Text text, Vector3 position, Camera camera);"

To me, this looks like the first line of a method, but I can't find the method body. When it's used in TMP_TextEventHandler's LateUpdate() method, it just seems to magically return the index of the word under the mouse pointer. I can see that it's being passed the mouse position, text element, and camera, but where are the "inner workings" of FindNearestWord() that convert these arguments into the returned int?

I hope this question makes sense, it's driving me a bit crazy.

Here's a screenshot

 

If you have installed TextMeshPro through package manager, you should find the source in <path-to-project>\Library\PackageCache\com.unity.textmeshpro

Other option would be to decompile <path-to-project>\Library\ScriptAssemblies\Unity.TextMeshPro.dll with ILSpy.

 

Thanks for the replies, I'm using Unity2020.1.2, and I have TMP version 3.0.1. I couldn't remember how I got TMP, but it's activated in the package manager, and I haven't got any TMP files in my asset store history.

I can access the folder you mention for \com.unity.texmeshpro and I can find the TMP_TextUtilities.cs file, which includes all the function bodies that were missing before, so that's great, I can at least see how they're working now.

Is there likely to be any reason why these don't show up in visual studio? It feels like TextEventHandler is on a different "level" of accessibility than TMP_TextUtilities, for example, I can't find TMP_TextUtilities by searching in my Unity project. It also comes up in this purple tab on the right hand side of VS.
