Godef prints the source location of definitions in Go programs.
godef [-t] [-a] [-A] [-o offset] [-i] [-f file][-acme] [expr]
File specifies the source file in which to evaluate expr. Expr must be an identifier or a Go expression terminated with a field selector.
If expr is not given, then offset specifies a location within file, which should be within, or adjacent to an identifier or field selector.
If the -t flag is given, the type of the expression will also be printed. The -a flag causes all the public members (fields and methods) of the expression, and their location, to be printed also; the -A flag prints private members too.
If the -i flag is specified, the source is read from standard input, although file must still be specified so that other files in the same source package may be found.
If the -acme flag is given, the offset, file name and contents are read from the current acme window.
