.gitignore exclude folder but include specific subfolder

Question

I have the folder application/ which I add to the .gitignore. Inside the application/ folder is the folder application/language

Just another example of walking down the directory structure to get exactly what you want. Note: I didn't exclude Library/ but Library/**/*

# .gitignore file
Library/**/*
!Library/Application Support/
!Library/Application Support/Sublime Text 3/
!Library/Application Support/Sublime Text 3/Packages/
!Library/Application Support/Sublime Text 3/Packages/User/
!Library/Application Support/Sublime Text 3/Packages/User/*macro
!Library/Application Support/Sublime Text 3/Packages/User/*snippet
!Library/Application Support/Sublime Text 3/Packages/User/*settings
!Library/Application Support/Sublime Text 3/Packages/User/*keymap
!Library/Application Support/Sublime Text 3/Packages/User/*theme
!Library/Application Support/Sublime Text 3/Packages/User/**/
!Library/Application Support/Sublime Text 3/Packages/User/**/*macro
!Library/Application Support/Sublime Text 3/Packages/User/**/*snippet
!Library/Application Support/Sublime Text 3/Packages/User/**/*settings
!Library/Application Support/Sublime Text 3/Packages/User/**/*keymap
!Library/Application Support/Sublime Text 3/Packages/User/**/*theme

> git add Library
