internal/lsp: improve completion support for untyped constants Add some extra smarts when evaluating untyped constants as completion candidates. Previously we called types.Default() on the expected type and candidate type, but this loses the untypedness of an untyped constant which prevents it from being assignable to any type or named type other than the untyped constant's default type. Note that the added logic does not take into account the untyped constant's value, so you will still get some false positive completions (e.g. suggesting an untyped negative integer constant when only a uint would do). Unfortunately go/types doesn't provide a way of answering the question "is this *types.Const assignable to this types.Type" since types.AssignableTo only considers a constant's type, not its value.

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.
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.
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.
