internal/lsp/regtest: add functions to make diagnostic assertions easier One of the tricky things about asserting on conditions in regtests is the asynchronous nature of LSP. For example, as the LSP client we cannot be sure when we've received all diagnostics for a given file. Currently, regtests are implemented by awaiting specific diagnostic expectations. This means that if gopls generates diagnostics that do not match those expectations, we can only time out the test. Ideally, we would want to know that gopls is done generating all diagnostics for the current file state. This is not possible without knowing the status of diagnostics for. Barring this, we would want to know that diagnostics are done for the current file version. Unfortunately, that also is not possible, because a new version of file B can affect diagnostics in file A. So in lieu of this information, this CL exposes a few tools that can be used to improve the experience of writing new regtests. - A new expectation is added: AnyDiagnosticAtCurrentVersion, that is satisfied if any diagnostics have been received for the current buffer version. - ExpectDiagnostics is added to Env, to help check whether the current diagnostics matches expectations.

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 golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
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.
