The Go programming language

When we first wrote the method set definition, we had long discussions about whether method sets applied to all types or just named types, and we (or at least I) concluded that it didn't matter: the two were equivalent points of view, because the only way to introduce a new method was to write a method function, which requires a named receiver type. However, the addition of embedded types changed this. Embedding can introduce a method without writing an explicit method function, as in: var x struct { sync.Mutex } var px *struct { sync.Mutex } var _, _ sync.Locker = &x, px The edits in this CL make clear that both &x and px satisfy sync.Locker. Today, gccgo already works this way; 6g does not. R=golang-dev, gri, iant, r CC=golang-dev https://golang.org/cl/5702062 |

This is the source code repository for the Go programming language. For documentation about how to install and use Go, visit http://golang.org/ or load doc/install.html in your web browser. After installing Go, you can view a nicely formatted doc/install.html by running godoc --http=:6060 and then visiting http://localhost:6060/doc/install.html. Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file. -- Binary Distribution Notes If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this README). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install.html). You should also add the Go binary directory $GOROOT/bin to your shell's path. For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile: export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin See doc/install.html for more details.
