The Go programming language
f2dc50b48d
There are three classes of methods/functions called Error: a) The Error method in the just introduced error interface b) Error methods that create or report errors (http.Error, etc) c) Error methods that return errors previously associated with the receiver (Tokenizer.Error, rows.Error, etc). This CL introduces the convention that methods in case (c) should be named Err. The reasoning for the change is: - The change differentiates the two kinds of APIs based on names rather than just on signature, unloading Error a bit - Err is closer to the err variable name that is so commonly used with the intent of verifying an error - Err is shorter and thus more convenient to be used often on error verifications, such as in iterators following the convention of the sql package.

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.
