Muir Manders 8938cee73c internal/lsp/completion: fix invalid struct literal field snippet
In cases like:

    type foo struct { a int; b float64 }
    foo{b<>}

We were completing to "foo{int(b: <float64>)}" (the problem being the
nonsensical int() conversion).

The expected type at "<>" is int to allow completions to match "a".
When we pass the *types.Var representing "b" through the candidate
matching machinery, we say "Oh, a float64! I can convert that to my
expected type of int!".

Fix by bailing out of candidate matching early if the candidate is a
composite literal struct field name. Field names aren't really objects
you can do anything to.

Fixes golang/go#43789.

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.
