internal/lsp/fake: reflect on-disk changes in clean buffers

If an open buffer is unmodified from the on-disk version, and that
on-disk content changes, VS Code will update the buffer with the change.
This is relevant for our quick fixes that use the go command to make
changes to go.mod/sum -- we want tests to pick up the changes without
needing to close/reopen the buffer.

For whatever reason, VS Code doesn't do this for deletions, and it made
the implementation easier, so I followed suit. I also mimicked its
behavior of sending both in-memory and on-disk change notifications.

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.

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.
