This would reflect Python's os.pathsep, not to be confused with Python's os.sep or require('path').sep.
require('path').sep // returns '/' on my Debian
require('path').delimiter // it's undefined
Is this actual? What do you mean?
@langpavel I believe he's requesting that the delimiter property be added
Sounds fine to me. Who wants to make the pull req? Should be a very short patch. Include docs and tests, please.
Should go on path, not os.
Platform specific path.delimiter as requested #3728
path: add platform specific path delimiter
