Go naming conventions for const
GoConstantsNaming ConventionsGo Problem Overview
I'm trying to determine whether there is a naming convention for the names of const in Golang.
I personally would tend to follow the C style and write them in upper case, but I haven't found anything on this page http://golang.org/doc/effective_go.html which seems to list some naming conventions for the language.
Go Solutions
Solution 1 - Go
The standard library uses camel-case, so I advise you do that as well. The first letter is uppercase or lowercase depending on whether you want to export the constant.
A few examples:
md5.BlockSizeos.O_RDONLYis an exception because it was borrowed directly from POSIX.os.PathSeparator

Use mixed caps.
Solution 3 - Go
Specific examples. Note that declaring the type in the constant (when relevant) can be helpful to the compiler.
// Only visible to the local file
const localFileConstant string = "Constant Value with limited scope"
// Exportable constant
const GlobalConstant string = "Everyone can use this"
