Rob Findley 18795da840 internal/typeparams: a new helper library for working with generic code 
Tools like gopls will want to add additional features to support working
with generic code, but need to continue to compile at older Go versions
that don't support type parameters.

This CL contains an initial draft of a helper library that may be used
to interrogate generic type information from go/ast and go/types without
having to guard the calling code with a build constraint.

I will use this library to implement some generics features for gopls.
Once we're confident in the API, it could potentially be exported as
x/tools/go/typeparams.

Go Tools

PkgGoDev

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.

JS/CSS Formatting

This repository uses prettier to format JS and CSS files.

The version of prettier used is 1.18.2.

It is encouraged that all JS and CSS code be run through this before submitting a change. However, it is not a strict requirement enforced by CI.

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.
