|
|
|
* root dirs were merged together.

|
|
|
* I.e. for the example above 'rootDirs' will have two entries: [ '/local/src', '/shared/components/contracts/src' ].
|

|
|
|
* Compiler wil first convert './protocols/file2' into absolute path relative to the location of containing file:
|
|
|
|
|
* '/local/src/content/protocols/file2' and try to load it - failure.
|
|
|
|
|
* Then it will search 'rootDirs' looking for a longest matching prefix of this absolute path and if such prefix is found - absolute path will
|
|
|
|
|
* be converted to a path relative to found rootDir entry './content/protocols/file2' (*). As a last step compiler will check all remainining
|
|
|
|
|
* entries in 'rootDirs', use them to build absolute path out of (*) and try to resolve module from this location.
