Hi,
yesterday I have tried to find some information about #library,
#source, #import and the Dart editor.
Now here is what I have learned:
#library
----------
1)
Indicates a source file to be used as a library.
The name given as in:
#library("name");
is without importance for the compiler.
But the Dart Editor uses these names for the Tools/Libraries view.
2)
If no #library declaration is given in the file with the "main"
function,
the compiler will add implicitly:
#library("filename");
3)
Only one "main" function per program (and library) is allowed.
#source
-----------
This links a single file.
Linking happens by using a file path as in:
#source("path/of/xxx.dart");
You can link a file with a #library declaration only via #import.
#import
-----------
This links a file and its linked files.
Linking happens by using a file path as in:
#import("path/of/xxx.dart");
or
#import("path/of/xxx.dart", prefix: "somePrefix");
You can link a file with a #library declaration only via #import.
Dart editor: Tools/Libraries view
---------------------------------------------
1)
The Libraries folder structure corresponds to the #import structure
but not the folder structure of the file system.
2)
The Libraries folder names correspond to the names given in the
#library("name")
declarations.

Hi,
After saw this post, I decided we need a wiki to store this type of information, maybe you can copy this here, I remember when I started at dart it was one of the more difficults things to understand when to use #source, and #import and #include.
