Method: Inline.rootdir

Defined in:
lib/inline.rb

.rootdir ⇒ Object

rootdir can be forced using INLINEDIR variable if not defined, it should store in user HOME folder

Under Windows user data can be stored in several locations:

HOME
HOMEDRIVE + HOMEPATH
APPDATA
USERPROFILE

Perform a check in that other to see if the environment is defined and if so, use it. only try this on Windows.

Note, depending on how you’re using this (eg, a rails app in production), you probably want to use absolute paths.
