imports: don't remove imports that conflict with globals

When a package contains both a var and an import that produce the same
identifier, the compiler will complain. I had thought that it made sense
to remove the redundant imports in that case. However, we can't reliably
tell whether a global from one file is in scope in another file. Most
notably, having multiple main packages in the same directory is pretty
common, and if someone declares a var in one that matches an import in
another, we don't want to remove the import.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.

Report Issues / Send Patches

This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.

The main issue tracker for the tools repository is located at https://github.com/golang/go/issues. Prefix your issue with “x/tools/(your subdir):” in the subject line, so it is easy to find.
