Heschi Kreinick 82fe25c375 gopls/doc: improve enum value documentation
Add a new field to the options JSON, EnumValues. Use it to automatically
generate the documentation for enums. Fix the displayed type to be
"enum" rather than the full-qualified Go type name.

To make this easy, I changed the various enum constants to be strings,
with values matching their configuration values. It may be possible to
automatically parse them in the future, but we can get to that later.

The documentation for hoverKind's private values is a little janky. I
didn't want to build a way to hide them. We can hardcode it if we really
care.

Updates golang/go#33544.

Heschi Kreinick 4aa5c68dc7 internal/lsp: remove multi-module test cases
As we begin testing multi-module workspace, clean up existing
multi-module marker tests. Most of their coverage was redundant with reg
tests already. Add a couple to cover the remainder.

This is probably not strictly necessary but it was easier to remove the
tests than worry about how to support them in multi-module mode.

Rob Findley 6ec2cde963 internal/lsp/source: add some additional symbol downranking
Downrank symbols if they are:
 1. Unexported and outside of the workspace. Since one wouldn't jump to
    these symbols to e.g. view documentation, they are less relevant.
 2. Fields and interface methods. Usually one would jump to the type
    name, so having fields highly ranked can be noisy.

To facilitate this change and more generally clean up, symbolCollector
is refactored to pass around slices of *ast.Idents rather than build up
'.' separated names as it traverses nested nodes.

doc).

not yet testable. Clients will need to add support for change

write settings.md.

I assumed that everything not explicitly documented was experimental,

experimental; I hope it's not long for this world, personally.

Along the way, rename many fields, make the enum matching case

It's useful to be able to switch between case sensitive, case
insensitive, and fuzzy matching for symbol without having to reload
gopls. FZF has some nice syntax for this:
  https://github.com/junegunn/fzf#search-syntax

Adopt a subset of this syntax for our symbol search:
  ' for exact matching
  ^ for prefix matching
  $ for suffix matching

It would be straightforward to also support inversion, using
'!', but I deemed this unnecessary.

I think we should adopt this, since none of these symbols conflicts with
Go identifiers, or (AFAIK) with special syntax in major LSP clients.

but now the secondary diagnostic is also converted into a

Rob Findley e2cc5a1191 gopls/integration/regtest: move regtests to the gopls module
Regtests are slow, and make `go test ./internal/lsp/...` slow. Also,
having them in the tools module means they can't use staticcheck,
go-diff, etc.

Move them to the gopls module. This means that they're annoying to work
with unless you open the gopls module, but hopefully that annoyance will
be gone soon when we support multi-module workspaces.

Rob Findley f2c07d7d8e internal/lsp/lsprpc: improvements to daemon logging
The gopls daemon had different default logging behavior than the sidecar
gopls: by default, the daemon was started with -logfile=auto.
Additionally, because most logs are reflected back to the forwarder, the
actual daemon logs have very little (if any) information.

This means that if you simply start gopls with -remote=auto, you'll get
a single logfile named /tmp/gopls-<pid>.log, which is mostly empty. This
is not a delightful experience.

Fix this via several improvements:
 + Log lifecycle events in the Daemon, to give the log a purpose.
 + Give the daemon a new default log location:
   /tmp/gopls-daemon-<pid>.log.
 + Don't pass -logfile=auto to the daemon by default.

zikaeroh 0cc1aa72b3 gopls/internal/hooks, internal/lsp/source: only match full words in link regexes
The current URL regexes (including xurls) match links in any part of a
string. However, this leads to odd underlining within words which just
so happen to have valid domain names as substrings. For example, a
comment which contains "reflect.DeepEqual" will match the URL regex as
"reflect.de" is a domain name.

Ensure that the URLs only match full regex words by adding \b around the
expressions. For xurls, this is done by pulling the expression out of
Relaxed() and recreating the Regexp.

While I'm here, make the non-gopls module expression prefer the longest
match, as xurls does.

Some code lenses may be undesirable for certain users or editors -- for
example a code lens that runs tests, when VSCode already supports this
functionality outside of the LSP. To handle such situations, support
configuring code lenses via a new 'codelens' gopls option.

Add support for code lens in regtests, and use this to test the new
configuration. To achieve this, thread through a new 'EditorConfig' type
that configures the fake editor's LSP session. It made sense to move the
test Env overlay onto this config object as well.

While looking at them, document some types in source.Options.

Rob Findley 30fd94b347 internal/lsp/lsprpc: expose configuration for auto-started daemon
Three new flags are added to the serve command, and threaded through to
the LSP forwarder:
 -remote.listen.timeout: -listen.timeout for the auto-started daemon
 -remote.debug: -debug for the auto-started daemon
 -remote.logfile: -logfile for the auto-started daemon

As part of this change, no longer enable debugging the daemon by
default.

Notably none of this configuration affects serving, so modifying this
configuration has been chosen not to change the path to the automatic
daemon. In other words, this configuration has effect only for the
forwarder process that starts the daemon: all others will connect to the
daemon and inherit whatever configuration it had at startup. This should
be OK, because in the common case this configuration should be static
across all clients (e.g., many Vim sessions all sharing the same
.vimrc).

Exposing this configuration made the signature of lsprpc.NewForwarder
a bit hard to understand, so I decided to go ahead and switch to a
variadic options pattern for initializing both the Forwarder and
StreamServer, the latter just for consistency with the Forwarder.

Rob Findley 20f46356b3 internal/lsp/lsprpc: add a handshake between forwarder and remote
In the ideal future, users will have one or more gopls instances, each
serving potentially many LSP clients. In order to have any hope of
navigating this web, clients and servers must know about eachother.

To allow for such an exchange of information, this CL adds an additional
handler layer to the serving configured in the lsprpc package. For now,
forwarders just use this layer to execute a handshake with the LSP
server, communicating the location of their logs and debug addresses.

Rob Findley e02f5847d1 internal/lsp/debug: move all debug state onto the Instance
For testability, and to support the exchange of debug information across
Forwarder and server, it is helpful to encapsulate all debug information
on the instance object.

This CL moves all state in the debug package into a new 'State' type,
that is added as a field on the debug.Instance. While doing so, common
functionality for object collections is factored out into the objset
helper type.

Also add two new debug object types: Client and Server. These aren't yet
used, but will be in a later CL (and frankly it was easier to leave them
in this CL than to more carefully rewrite history...).

Heschi Kreinick f7b8cc7bd0 internal/span,lsp: disambiguate URIs, DocumentURIs, and paths
Create a real type for protocol.DocumentURIs. Remove span.NewURI in
favor of path/URI-specific constructors. Remove span.Parse's ability to
parse URI-based spans, which appears to be totally unused.

As a consequence, we no longer mangle non-file URIs to start with
file://, and crash all over the place when one is opened.

Updates golang/go#33699.

Rebecca Stambler 2ee7536ab1 internal/lsp: remove nilness analyzer
The nilness analyzer requires SSA, which is very expensive to build and
uses a lot of RAM. It also seems to really shoot up memory usage when it
hits certain cases, which is causing a lot of problems for users.
Disable this analysis - we'll leave SSA to staticcheck.

Updates golang/go#36639

Rebecca Stambler 6822f1ada4 internal/lsp: disable nilness analyzer, unless staticcheck enabled
Users with staticcheck enabled will be more tolerant of increased RAM
usage. We might be able to disable this check entirely once the next
version of staticcheck is released with a similar analysis (https://staticcheck.io/docs/checks#SA5011).
