The Go programming language
7b6ee1a5d4
This CL is only cut-and-paste, moving code around.
Moving it in a separate CL should simplify the diffs in later CLs.
There are three patterns here.
1. A function like
func (v Value) M() (...) {
return v.panicIfNot(K).(*kValue).M()
}
becomes
func (v Value) M() (...) {
vv := v.panicIfNot(K).(*kValue)
// body of (*kValue).M, s/v./vv./g
}
2. A function like
func (v Value) M() (...) {
return v.panicIfNots(kList).(mer).M()
}
becomes
func (v Value) M() (...) {
switch vv := v.panicIfNots(kList).(type) {
case *k1Value:
// body of (*k1Value).M, s/v./vv./g
case *k2Value:
// body of (*k2Value).M, s/v./vv./g
...
}
panic("not reached")
}
3. The rewrite of Value.Set follows 2, but each case
is built from the bodies of (*kValue).SetValue and (*kValue).Set.
func (v *kValue) SetValue(x Value) {
v.Set(x.panicIfNot(K).(*kValue)
}
func (v *kValue) Set(x *kValue) {
... body
}
becomes, in the switch from 2,
case *kValue:
xx := x.panicIfNot(K).(*kValue)
... body, s/v./vv./g; s/x./xx./g

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.

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.
