Google today announced language version 1 of its Go language, or Go 1 for
short. Downloadable at the Go website, the open source Go has been positioned
as a general-purpose language suitable for uses ranging from application
development to systems programming and offering such features as garbage
collection and concurrency. It also is intended to be easy to program. Go 1 is
the first release supporting binary distributions, which are available in
Linux, FreeBSD, Mac OS X, and Windows. The language also integrates with
Google's App Engine cloud platform. "The driving motivation for Go 1 is
stability for its users. People who write Go 1 programs can be confident that
those programs will continue to compile and run without change, in many
environments, on a time scale of years. Similarly, authors who write books
about Go 1 can be sure that their examples and explanations will be helpful to
readers today and into the future," according to a post from Go team
member Andrew Gerrand on the Go language blog. Google also is striving for
forward compatibility; version 1 is a representation of Go as it is used today
and is not a major redesign, Gerrand said. But it introduces changes such as
new types for Unicode characters and errors. The package hierarchy has been
rearranged to group related items together.
"In its planning, we focused on cleaning up problems and
inconsistencies and improving portability. There had long been many changes to
Go that we had designed and prototyped but not released because they were
backward-incompatible. Go 1 incorporates these changes, which provide
significant improvements to the language and libraries but sometimes introduce
incompatibilities for old programs. Fortunately, the go fix tool can automate
much of the work needed to bring programs up to the Go 1 standard,"
Gerrand said. The Go tool suite is being structured around the go command,
which is a program for fetching, building, installing, and maintaining Go code.
This command eliminates the need for Makefiles to write Go code. Go 1 also
triggers a new release of Google App Engine SDK. In envisioning Go, Google has
sought to address what it sees as a need for faster software development and
accommodating multicore chips. Go is intended to enable compiling of large
programs in a few seconds on a single computer and provide a model for software
construction making dependency analysis easy.
