A common annoying mis-completion is as follows:
type foo struct {

func (f foo) Field() int { return f.field }
func (f foo) logic() {
if f.f<>

Now at <> we prefer "field" over "Field()". Similarly:
type foo struct {
}
func (f foo) DoSomething() { }
func (f foo) doSomething() { }
func (f foo) logic() {
f.d<>
}
Now at <> we prefer "doSomething()" over "DoSomething()". All else
being equally, you normally want private objects over public objects
when the private objects are available.
The same logic is applied to deep completions so we prefer "c.foo.bar"
over "c.Foo().bar".

When searching for deep completions, we can end up enumerating struct
types' fields a lot. Optimize fieldSelections to reduce work:
- Wait until we see an embedded field before we create the "seen"
map.
- Use a callback style to iterate over the struct's fields rather than
returning a slice of fields.
- Change "seen" checking strategy back to track struct types rather
than each individual field.
Struct with 5 non-embedded fields:
name old time/op new time/op delta
Fields-16 293ns ± 1% 20ns ± 2% -93.13% (p=0.008 n=5+5)
name old alloc/op new alloc/op delta
Fields-16 120B ± 0% 0B -100.00% (p=0.008 n=5+5)
name old allocs/op new allocs/op delta
Fields-16 4.00 ± 0% 0.00 -100.00% (p=0.008 n=5+5)
Same struct but add an embedded struct with 2 fields:
name old time/op new time/op delta
Fields-16 389ns ± 1% 142ns ± 1% -63.53% (p=0.008 n=5+5)
name old alloc/op new alloc/op delta
Fields-16 120B ± 0% 144B ± 0% +20.00% (p=0.008 n=5+5)
name old allocs/op new allocs/op delta
Fields-16 4.00 ± 0% 2.00 ± 0% -50.00% (p=0.008 n=5+5)
I think the alloc/op went up because the "seen" map is no longer
allocated on the stack. There is more room for more optimization, but
it's probably not worth making things more complicated.

Now we properly offer "case" and "default" keyword completion in cases
like:
switch {

}
First I had to add an AST fix for empty switch statements to move the
closing brace down. For example, say the user is completing:
switch {
ca<>
}
This gets parsed as:
switch {
}
Even if we manually recover the "ca" token, "<>" is not positioned
inside the switch statement anymore, so we don't know to offer "case"
and "default" candidates. To work around this, we move the closing
brace down one line yielding:
switch {
}
Second I had to add logic to manually extract the completion prefix
inside empty switch statements, and finally some logic to offer (only)
"case" and "default" candidates in empty switch statements.

offers the candidate:
if err != nil {
return 0, <err>

The completion will only be offered when:
1. The position is in a function that returns an error as final result
value, and
2. The statement preceding position is an assignment whose final LHS
value is an error.
The completion will contain zero values for the non-error return values
as necessary.
Using the above example, the completion will be offered after the user

i
if
if err
Basically the candidate will be offered after every keystroke as the
user types "if err".

Offer "struct", "interface", "map", "chan", and "func" keywords when

Because "struct" and "interface" are more often used when declaring
named types, they get a higher score in type declarations. Otherwise,
"map", "chan" and "func" get a higher score.
I also got rid of the special keyword scoring. Now keywords just use
stdScore and highScore. This makes the interplay with other types of
candidates more predictable. Keywords are offered in pretty limited
contexts, so I don't think they will be annoying.
Finally, keyword candidate score is now to be scaled properly based on
how well they match the prefix. Previously they weren't penalized for
not matching well, so there were probably some situations where
keywords were ranked too high.

Now "implementations" supports finding interfaces implemented by the
specified concrete type. This is the inverse of what "implementations"
normally does. There isn't currently a better place in LSP to put this
functionality. The reverse lookup isn't an important feature for most
languages because types often must explicitly declare what interfaces
they implement.
An argument can be made that this functionality fits better into find-
references, but it is still a stretch. Plus, that would require
find-references to search all packages instead of just transitive
dependents.

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

The code to check if a candidate object matches our candidate
inference had become complicated, messy, and in some cases incorrect.
The main source of the complexity is the "derived" expected and
candidate types. When considering a candidate object "foo", we also
consider "&foo", "foo()", and "*foo", as appropriate. On the expected
side of things, when completing the a variadic function parameter we
expect either the variadic slice type and the scalar element type.
The code had grown organically to handle the expanding concerns, but
that resulted in confused code that didn't handle the interplay
between the various facets of candidate inference.
For example, we were inappropriately invoking func candidates when
completing variadic args:
func foo(...func())
func bar() {}
foo(bar<>) // oops - expanded to "bar()"
and we weren't type matching functions properly as builtin args:
func myMap() map[string]int { ... }
delete(myM<>) // we weren't preferring (or invoking) "myMap()"
We also had methods like "typeMatches" which took both a "candidate"
object and a "candType" type, which doesn't make sense because the
candidate contains the type already.
Now instead we explicitly iterate over all the derived candidate and
expected types so they are treated the same. There are still some
warts left but I think this is a step in the right direction.

return source interfaces rather than concrete types.
This CL changes cache.New and (*Cache).NewSession to return concrete

argue that this makes sense from a philosophical perspective: everything

When completing members on a type checked, unimported package, you get
fully typed members. That means you get deep completions. Because we
downrank the initial unimported package members so much, any deep
completions were dominating the rankings. For example
context.Back<>
yielded "context.Background().Err" ranked above "context.Background".
Fix by scoring context.Background in this example as
stdScore+tinyRelevanceScore instead of just tinyRelevanceScore. I also
changed untyped candidate scores in the same way so they stay
competitive when you have both imported and unimported candidates.
The other option was to propagate the score penalty into deep
candidates, but that wasn't easy. In general I think you are better off
avoiding big score penalties because they complicate the interplay
between different kinds of candidates. Scoring needs an overhaul, but
at least we are building up our test suite in the meantime.

As we can see, any folder inside of testdata should be of this format, where the primary test files with the markers are all located inside the primarymod folder. The modules folder is used to hold any potential dependencies that are used for testing.
A consequence of this change is that we can have one directory separated by folders, where each folder is it's own module, this allows us to use internal/lsp/tests with go.mod files. Now, tests.Load() will return an array of Data objects, where each object corresponds to one of the directories structured above.

Completion often fails when the completion prefix happens to be a
keyword. We previously tried to fix this with AST surgery, but
often the accidental keyword is not apparent looking at the AST.
For example:
chan<>
foo()
parses as CallExpr{Fun: ChanType{Value: Ident{"foo"}}} with very few
hints that something is wrong, and:
default
foo()
is completely omitted from the AST.
Rather than look in the AST, we now instead manually look for a
keyword token that contains the completion position. If we find one,
we treat that as our surrounding identifier.

The main goal is to push the package variant logic from internal/lsp
into internal/lsp/source so all users of internal/lsp/source benefit.
"references" and "rename" now have top-level source.References() and
source.Rename() entry points (as opposed to hanging off
source.Identifier()). I expanded objectsAtProtocolPos() to know about
implicit objects (type switch and import spec), and to
handle *ast.ImportSpec generically. This gets rid of special case
handling of *types.PkgName in various places.
The biggest practical benefit, though, is that "references" no longer
needs to compute the objectpath for every types.Object comparison it
does, instead using direct types.Object equality. This speeds up
"references" and "rename" a lot.
Two other notable improvements that fell out of not using
source.Identifier()'s logic:
- Finding references on an embedded field now shows references to the
field, not the type being embedded.
- Finding references on an imported object now works
correctly (previously it searched the importing package's dependents
rather than the imported package's dependents).
Finally, I refactored findIdentifier() to use pathEnclosingObjNode()
instead of astutil.PathEnclosingInterval. Now we only need a single
call to get the path because pathEnclosingObjNode() has the
"try pos || try pos-1" logic built in.

In cases like:
var foo *someType = bar.(some<>)
We will now complete "some" to "*someType". This involved two changes:
1. Properly detect expected type as *someType in above example. To do
this I just removed *ast.TypeAssertExpr from
breaksExpectedTypeInference() so we continue searching up the AST for
the expected type.
2. If the given type name T doesn't match, also try *T. If *T does
match, we mark the candidate as "makePointer=true" so we know to
prepend the "*" when formatting the candidate.

This change moves to our ultimate approach of diagnostics the snapshot
on every file change, instead of carefully picking which files and
packages to diagnose. Analyses are shown for packages whose files are
open in the editor. Reverse dependencies are no longer needed for
source.Diagnostics because they will be invalidated when the snapshot is
cloned, so diagnosing the entire snapshot will bring them up to date.
This even works for go.mod files because all of workspace-level `go list`s
will be canceled as the user types, and then we trigger an uncancellable
go/packages.Load when the user saves. There is still room for improvement
here, but it will require much more careful invalidation of metadata for
go.mod files.

This change moves as much view initialization code into the
initialization function, instead of having it happen on view create.
Also, the `go env` variables that are collected at inconsistent times
are all collected on view creation. That is sufficient, since the view
is recreated if the environment changes.
I had originally hoped that the initial call to `go env` and the
-modfile detection could become part of this parallel initialization as
well, but you can't create a *packages.Config until the temporary
modfile has been set up, so it still makes sense to do that on view
create. This is, however, the reasoning behind the refactorings in
the -modfile detection in this CL. The main changes are a few renamings
and a split between snapshot.ModFiles and view.modFiles to maximize the
amount of work done in the view. I changed view.modfiles to moduleInformation
because I thought we might want to store additional information there at some
point. Rohan, please let me know if you disagree with any of the changes I made,
and I can revert them.

We have multiple use cases for scanning: goimports, import completion,

and the latter have very different performance considerations. Scanning
everything all at once and returning it was not good enough for them.
Instead, design the API as a series of callbacks for each
directory/package: first we discover its existence, then we load its
package name, then we load its exports. At each step the caller can
choose whether to proceed with the package. Import completion can stop
before loading exports, goimports can apply its directory name
heuristics, and in the future we'll be able to stop the scan short once
we've found all the results we want for completions.

VSCode doesn't like (read: ignores) candidates whose filterText begins
with "&", so trim it off.
I also tweaked "addressed" candidates to include the "&" prefix in the
item label as well so the user can see what they will get.

We now support taking the address of objects to make better completion
candidates. For example:
i := 123
var p *int = <> // now you get a candidate for "&i"
This required that we track addressability better, particularly when
searching for deep candidates. Now each candidate knows if it is
addressable, and the deep search propagates addressability to child
candidates appropriately.
The basic propagation logic is:
- In-scope *types.Var candidates are addressable. This handles your
basic "foo" variable whose address if "&foo".
- Surrounding selector is addressable based on type checker info. This
knows "foo.bar.<>" is addressable but "foo.bar().<>" isn't
- When evaluating deep completions, fields after a function call lose
addressability, but fields after a pointer regain addressability. For
example, "foo.bar()" isn't addressable, but "foo.bar().baz" is
addressable if "bar()" returns a pointer.

This is the start of a significant refactoring to implementations,
references, and rename (i.e. everything that searches across
packages). The main goal of the refactoring is to push the package
variant logic from internal/lsp into internal/source so that all users
of source benefit, not just internal/lsp. It also makes it easier to
write tests for various cases because the source tests invoke the
source package directly (so previously did not include all the package
variants).
Currently source.Identifer() handles lots of disparate use cases.
Things like definition and hover don't care about package variants but
do care about other random bits of info that may not apply to
implementations or references. So, I'm splitting implementations out
from source.Identifier. As I work through references and rename
hopefully things will end up separated into smaller chunks.
I also improved implementation deduping to happen earlier. I thought I
could dedupe using obj.Pos(), but mirror objects in package variants
have different positions (suggesting they aren't reusing the
same *ast.File). Instead I used token.Position to dedupe.

If the enclosing value spec specifies a type on the LHS, we now prefer
completions of that type on the RHS. For example:

I also added a special case to lexical() to know that we can't offer
objects defined on the LHS as completions on the RHS. For example:

There is an issue when highlighting a single character identifier if the cursor is on the right of it. This problem
is a result of an assumption made in astutil.PathEnclosingInterval relating to the arguments passed in. Specifically,
if start==end, the 1-char interval following start is used instead. As a result, we might not get an exact match
so we should check the 1-char interval to the left of the passed in position to see if that is an exact match.

flag which allows a user to run a go command but choose where to direct the

This change starts setting up the infrastructure to handle the seperate modfile

if 1.14 is contained.

Having nil ranked normally causes it to show up as the top candidate
in cases like:
context.WithCancel(<>) // "nil" shows up before "context.Background()"
"context.Background()" gets a slight score penalty since it is a deep
completion, so "nil" is ranked highest.
Sometimes you do want "nil", but it's such a short identifier you
probably aren't leaning too heavily on autocompletion. I think it
makes sense to optimize for the case when you want something non-nil.
