Just so I remember, when defining tasks, these variables are predefined in VS Code:

```
file:                     /Users/joe/Documents/src/cpp/design-patterns/stl/streams/streams.cpp
workspaceFolderBasename:  design-patterns
relativeFile:             stl/streams/streams.cpp
fileBasename:             streams.cpp
fileBasenameNoExtension:  streams
fileExtname:              .cpp
lineNumber:               14
selectedText:             Some selected text
```
