I'm currently developing an editor that will implement syntax highlighter for a rather specialized language. I had already found a vim highlighting file that I rather liked the style of, and while I can't use code from it directly - since my project is in Qt/C++ - I would like to use the syntax structure/design they used (i.e. the groupings of what gets highlighted how).
If I'm simply using the design of their code, rather than any actual code itself, do I credit them in my syntax highlighting code? If so, how would I do that? My gut says that I do, but I thought I should ask here because I'm an rather new to all this.
The code I would like to base from is licensed under an MIT license, and my project uses GPLv3.
