go.xclangspec
|

Go language specification for Xcode 4.x.
|
||||
|
||||
This is a preliminary version that supports basic syntax coloring
|
||||
(such as keywords, literals, and comments) and an attempt to provide
|
||||
some structure information (incomplete).
|
||||
|
||||
There is not much documentation available regarding the format
|
||||
of .xclangspec files. As a starting point, see for instance the
|
||||
outdated documentation at:
|

|
||||
http://maxao.free.fr/xcode-plugin-interface/specifications.html
