internal/lsp/analysis/fillreturns: implement matching in fillreturns

The existing implementation looks for matching types in the declaration
and the leftmost value in the return statement. Instead, the analyzer
now searches across all the values in the return statement to find one
that matches the type in the declaration. Additionally, if a value in
the return statement does not match any type in the declaration, it is
not overriden.

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.

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
