The Go programming language
a87382e7b3
This CL defines a new, more Go-like representation of Go types (different structs for different types as opposed to a single Type node). It also implements an ast.Importer for object/archive files generated by the gc compiler tool chain. Besides the individual type structs, the main difference is the handling of named types: In the old world, a named type had a non-nil *Object pointer but otherwise looked no different from other types. In this new model, named types have their own representation types.Name. As a result, resolving cycles is a bit simpler during construction, at the cost of having to deal with types.Name nodes explicitly later. It remains to be seen if this is a good approach. Nevertheless, code involving types reads more nicely and benefits from full type checking. Also, the representation seems to more closely match the spec wording. Credits: The original version of the gc importer was written by Evan Shaw (chickencha@gmail.com). The new version in this CL is based largely on Evan's original code but contains bug fixes, a few simplifications, some restructuring, and was adjusted to use the new type hierarchy. I have added a comprehensive test that imports all packages found under $GOROOT/pkg (with a 3s time-out to limit the run-time of the test). Run gotest -v for details. The original version of ExportData (exportdata.go) was written by Russ Cox (rsc@golang.org). The current version is returning the internal buffer positioned at the beginning of the export data instead of printing the export data to stdout. With the new types package, the existing in-progress typechecker package is deprecated. I will delete it once all functionality has been brought over.

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.
