internal/lsp/mod: speed up and simplify go.mod code lenses

The tidy and upgrade code lenses first run the go command they
represent, then show the lens if there are changes to be made. While
this makes for a cleaner user experience, it also means that we're
running a go command that hits the network in a synchronous code lens
call. That's risky if the user is on a slow network connection.

Removing the call does represent a change, possibly a regression, in UX.
However, we already felt that the presentation of the upgrade option on
each dependency line was too noisy. Therefore the only remaining benefit
is that the lenses only appear when they have something to do. We've
decided that's not sufficient justification. Remove the calls.

We may recreate them as diagnostics in the future, so I've left
ModUpgrade around. (ModTidy is still used by diagnostics.)

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.


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

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.
