Peter Weinbergr a2250d31f3 internal/lsp: add gopls semtok command and semantic token tests
The command 'gopls semtok <file>.go' produces a version of <file>.go
decorated with comments describing tokens as semantic tokens. The
format is described towards the top of cmd/semantictokens.go.

There are also tests in testdata/semantic/. a.go is used by lsp_test.go
(with -cover) to show that essentially all of semantic.go is executed.
b.go illustrates the handling of strange, but legal, constructs
like 'const false = nil and non-ascii'. The .golden files show
the expected results.

The implementation will panic, rather than log, on unexpected state.

gopls semtok has been run on all the .go files in x/tools and in
the source distribution. There were no unexpected messages nor panics.

Heschi Kreinick e8435508c6 internal/lsp: run marker tests in multi-module mode
Multi-module mode works rather differently than module mode, so ideally
we should have good test coverage for it. We can get a lot for a little
by running the marker tests as a module in a multi-module workspace. To
do that, we can move everything one directory lower, and use the
original directory as the root of the workspace.

The mechanics of setting it up are a little distasteful but not too bad.
We prepend a directory to all the paths in the packagestest.Module, and
after Export, move the created go.mod down into that directory. The only
other change is to find the golden files in the right place.

Command line tests use URIs everywhere, and it was too annoying to fix
them, so I didn't bother. Unimported completion tests fail and are
skipped for the moment.

This change enables the multi-module workspace mode by default, so that
we can catch all of the test failures and edge cases. It is still
disabled in GOPATH mode and for any workspaces that contain a module
with a vendor directory.

A few minor changes had to be made to handle changes caused by the
workspace module pseudoversions.

As we have modified the ways that we control which analyzers get

analyzers from the main group so that the "staticcheck" setting can

Heschi Kreinick 6a8222ee25 gopls/doc: generate settings JSON, docs
gopls has many settings. We want to automatically generate
documentation, and we want to allow clients to perform their own
validation if they so desire.

Using all three of AST, type information, and reflection, generate a
JSON description of the settings and their default values. Add a gopls
command that prints it. Add a documentation generator that uses it to
write settings.md.

I assumed that everything not explicitly documented was experimental,
and moved it into that section. I also moved expandWorkspaceToModule to
experimental; I hope it's not long for this world, personally.

Along the way, rename many fields, make the enum matching case
insensitive, and add a stringer call so that the defaults print nicely.

Fixes golang/go#33544.

Heschi Kreinick 412b8bda49 internal/lsp/cache: ref-count snapshots
To manually collect cache entries, we need to know when a snapshot is
idle. Add a reference count in the form of a WaitGroup and keep track of
its uses. The pattern is that any time a snapshot is returned, it comes
with a release function that decrements the ref count.

Almost all uses of a snapshot originate in a user-facing request,
handled in beginFileRequest. There it's mostly an exercise in passing
Snapshots around instead of Views.

In the other places I took the path of least resistance. For file
modifications I tried to minimize the amount of code that needed to deal
with snapshots. For diagnostics I just acquired the snapshot at the
diagnostics call.

Rebecca Stambler 9267083701 internal/lsp: support refactor.extract through commands
The logic for extracting a function is quite signficant, and the code
is expensive enough that we should only call it when requested by the
user. This means that we should support extracting through a command
rather than text edits in the code action.

To that end, we create a new struct for commands. Features like extract
variable and extract function can supply functions to determine if they
are relevant to the given range, and if so, to generate their text
edits. source.Analyzers now point to Commands, rather than
SuggestedFixFuncs. The "canExtractVariable" and "canExtractFunction"
functions still need improvements, but I think that can be done in a
follow-up.

convenience analyzers, which are closer to commands. These represent
suggestions that won't necessarily improve the quality or correctness of
your code, but they offer small helper functions for the user.

This CL also combines the refactor rewrite tests with the suggested fix
tests, since they are effectively the same.

For now, we only support convenience analyzers when a code action was
requested on the same line as the fix. I'm not sure how to otherwise
handle this without bothering the user with unnecessary diagnostics.

In preparation for a later change where we alter the implementation of
the workspace Symbol method, we now specify the Name that should be used
when constructing a SymbolInformation value from a @symbol annocation.
There is no change in the test expectations.

Rebecca Stambler 4d14fc9c00 internal/lsp: add type error fixes to existing diagnostics
This change is the first step in handling golang/go#38136. Instead of
creating multiple diagnostic reports for type error analyzers, we add
suggested fixes to the existing reports. To match the analyzers for
FindAnalysisError, we add an ErrorMatch function to source.Analyzer.

This is not an ideal solution, but it was the best one I could come up
with without modifying the go/analysis API. analysisinternal could be
used for this purpose, but it seemed to complicated to be worth it, and
this is fairly simple. I think that go/analysis itself might need to be
extended for type error analyzers, but these temporary measures will
help us understand the kinds of features we need for type error
analyzers.

A follow-up CL might be to not add reports for type error analyzers
until the end of source.Diagnostic, which would remove the need for the
look-up.

Fixes golang/go#38136

Rebecca Stambler 3304cfb00f internal/lsp: temporarily disable type error analyzers by default
If we release gopls/v0.4.0 soon, we should keep these new analyzers off
by default. They were just merged, so they haven't been used enough to
be enabled, I think. We'll turn them on by default for gopls/v0.5.0.

Also, ended up creating a helper function to check if analysis has been
abled (which fixed a small bug in FindAnalysisError), and another helper
function to enable all analyses for testing purposes.

Peter Weinbergr 3e041465cc internal/lsp: change the type of CompletionItem.TextEdit back
The recent LPS protocol change made the definition of textEdit into
a union type, so the generated code made TextEdit an interface{},
which broke govim. This CL reverts it to a *TextEdit. The code
generator will be fixed in another CL.

We can revisit this when  gopls wants to start using the new
InsertReplaceEdit type.

Peter Weinberger 20ab64c0d9 internal/lsp: bring generated protocol code up to date; stop corrupting logs
1. logging at debug/rpc.go:105 was corrupting logs.
2. DocumentSymbol (a Server method) now returns []interface{}.
3. The latest version of the LSP changed CompletionItem.TextEdit to
possibly be of the new type InsertReplaceEdit, so the generated Go
code now has TextEdit an interface{} rather than a *TextEdit. This
required a change to tests/util.go.
4. The latest version also introduced several other new types,
and new members in some structs.

Tests pass and the I've use the new gopls a little.
