The Go programming language

CL submitted prematurely by mistake. ««« original CL description spec: clarify index and selector expressions 1) Explain a[i] and a[i:j] where a is of type *A as shortcut for (*a)[i] and (*a)[i:j], respectively. 2) Together with 1), because len() of nil slices is well defined, there's no need to special case nil operands anymore. 3) The result of indexing or slicing a constant string is always a non-constant byte or string value. 4) The result of slicing an untyped string is a value of type string. 5) If the operand of a valid slice a[i:j] is nil (i, j must be 0 for it to be valid - this already follows from the in-range rules), the result is a nil slice. Fixes #4913. Fixes #5951. R=rsc, r, iant, ken CC=golang-dev https://golang.org/cl/11884043 »»» R=r CC=golang-dev https://golang.org/cl/12170046 |

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.
