This commit adds support for calling rename from the gopls command
line, e.g.
$ gopls rename -w ~/tmp/foo/main.go:8:6
$ gopls rename -w ~/tmp/foo/main.go:#53
Optional arguments are:
- -w, which writes the changes back to the original file; and
- -d, which prints a unified diff to stdout
With no arguments, the changed files are printed to stdout.
It:
- adds internal/lsp/cmd/rename.go, which implements the command;
- adds "rename" to the list of commands in internal/lsp/cmd/cmd.go;
- removes the dummy test from internal/lsp/cmd/cmd_test.go; and
- adds internal/lsp/cmd/rename_test.go, which uses the existing
"golden" data to implement its tests.

We were recursing infinitely in cases like this:
switch true {
case true:
go foo.F<>
}
There were three things that came together to cause this:
1. We recently starting recursively fixing broken go/defer statements.
2. In this case we were failing to swap in the correct ast.Node in for
the *ast.BadStmt because we were only looking
for *ast.BlockStmt (and *ast.CaseStmt has no block).
3. After 2), we weren't returning an error so the fix() code thought
it should recurse.
Fix 2) by using reflection to swap AST nodes in a generic way. Perhaps
a bit overkill in this case, but I happened to have already written
this for an upcoming change, so I just pulled it in to fix this bug.
Fix 3) by returning an error if we fail to swap the AST nodes.

Now we will offer function literal completions when we know the
expected type is a function. For example:
sort.Slice(someSlice, <>)
will offer the completion "func(...) {}" which if selected will
insert:
func(i, j int) bool {<>}
I opted to use an abbreviated label "func(...) {}" because function
signatures can be quite long/verbose with all the type names in there.
The only interesting challenge is how to handle signatures that don't
name the parameters. For example,
func HandleFunc(pattern string, handler func(ResponseWriter, *Request)) {
does not name the "ResponseWriter" and "Request" parameters. I went
with a minimal effort approach where we try abbreviating the type
names, so the literal completion item for "handler" would look like:
func(<rw> ResponseWriter, <r> *Request) {<>}
where <> denote placeholders. The user can tab through quickly if they
like the abbreviations, otherwise they can rename them.
For unnamed types or if the abbreviation would duplicate a previous
abbreviation, we fall back to "_" as the parameter name. The user will
have to rename the parameter before they can use it.
One side effect of this is that we cannot support function literal
completions with unnamed parameters unless the user has enabled
snippet placeholders.

Add support for literal completion candidates such as "[]int{}" or
"make([]int, 0)". We support both named and unnamed types. I used the
existing type matching logic, so, for example, if the expected type is
an interface, we will suggest literal candidates that implement the
interface.
The literal candidates have a lower score than normal matching
candidates, so they shouldn't be disruptive in cases where you don't
want a literal candidate.
This commit adds support for slice, array, struct, map, and channel
literal candidates since they are pretty similar. Functions will be
supported in a subsequent commit.
I also added support for setting a snippet's final tab stop. This is
useful if you want the cursor to end up somewhere other than the
character after the snippet.

In api/*.txt, interface declarations are represented with lines like:

The latter form confuses mkstdlib into thinking that it's a method
because of the extra comma, and then it skips the interface entirely.

Improve the existing fix-the-AST code to better identify the
expression following the "go" or "defer" keywords:
- Don't slurp the expression start outside the loop since the
expression might only have a single token.
- Set expression end to the position after the final token, not the
position of the final token.
- Track curly brace nesting to properly capture an entire "func() {}"
expression.
- Fix parent node detection to work when BadStmt isn't first statement
of block.
- Add special case to detect dangling period, e.g. "defer fmt.". We
insert phantom "_" selectors like go/parser does to prevent the
dangling "." from messing up the AST.
- Use reflect in offsetPositions so it updates positions in all node
types. This code shouldn't be called often, so I don't think
performance is a concern.
I also tweaked the function snippet code so it properly expands
"defer" and "go" expressions to function calls. It thought it didn't
have to expand since there was already a *ast.CallExpr, but the
CallExpr was faked by us and the source doesn't actually contain the
"()" calling parens.
Note that this does not work for nested go/defer statements. For
example, completions won't work properly in cases like this:
go func() {
defer fmt.<>
}
I think we can fix this as well with some more work.

Invert "useDeepCompletions" config flag to "disableDeepCompletion" and
separate out "disableFuzzyMatching" which reverts to the previous
prefix matching behavior.
I separated fuzzy matching tests out to a separate file so they aren't
entangled with deep completion tests. In coming up with representative
test cases I found a couple issues which I fixed:
- We were treating a fuzzy matcher score of 0 as no match, but the
matcher returns 0 for candidates that match but have no bonuses. I
changed the matcher interface so that a score of 0 counts as a
match. For example, this was preventing a pattern of "o" from
matching "foo".
- When we lower a candidate's score based on its depth, we were
subtracting a static multiplier which could result in the score
going negative. A negative score messes up future score weighting
because multiplying it by a value in the range [0, 1) makes it
bigger instead of smaller. Fix by scaling a candidate's score based
on its depth rather than subtracting a constant factor.

Make use of the existing fuzzy matcher to perform server side fuzzy
completion matching. Previously the server did exact prefix matching
for completion candidates and left fancy filtering to the
client. Having the server do fuzzy matching has two main benefits:
- Deep completions now update as you type. The completion candidates
returned to the client are marked "incomplete", causing the client
to refresh the candidates after every keystroke. This lets the
server pick the most relevant set of deep completion candidates.
- All editors get fuzzy matching for free. VSCode has fuzzy matching
out of the box, but some editors either don't provide it, or it can
be difficult to set up.
I modified the fuzzy matcher to allow matches where the input doesn't
match the final segment of the candidate. For example, previously "ab"
would not match "abc.def" because the "b" in "ab" did not match the
final segment "def". I can see how this is useful when the text
matching happens in a vacuum and candidate's final segment is the most
specific part. But, in our case, we have various other methods to
order candidates, so we don't want to exclude them just because the
final segment doesn't match. For example, if we know our candidate
needs to be type "context.Context" and "foo.ctx" is of the right type,
we want to suggest "foo.ctx" as soon as the user starts inputting
"foo", even though "foo" doesn't match "ctx" at all.
Note that fuzzy matching is behind the "useDeepCompletions" config
flag for the time being.

Support renaming of identifiers in test packages. The packages for
all of the references must be checked and the changes need to be
deduped, since both a package and its test package contain some of the
same files.

Objects for builtin types all have position token.NoPos. We do
not want all objects that have position token.NoPos to be matched
when we are looking for references for this object, so we need to
compare the names of the objects as well.

The satisfy package has a precondition for Finder.Find that requires
that the package has no type errors. If this is a check that we would
perform, give an error and do not rename.

Add some extra smarts when evaluating untyped constants as completion
candidates. Previously we called types.Default() on the expected type
and candidate type, but this loses the untypedness of an untyped
constant which prevents it from being assignable to any type or named
type other than the untyped constant's default type.
Note that the added logic does not take into account the untyped
constant's value, so you will still get some false positive
completions (e.g. suggesting an untyped negative integer constant when
only a uint would do). Unfortunately go/types doesn't provide a way of
answering the question "is this *types.Const assignable to this
types.Type" since types.AssignableTo only considers a constant's type,
not its value.

Often anonymous functions can be passed as arguments to a function. In
these cases, it can be annoying for a user to see signature help for the
entire duration of their writing this function. This change detects if
the user is typing in a function literal and disables signature help in
that case.

Support the renaming of the imported name of a package within a file.
This case needs to be special cased because the ident may be added or
removed.

The identifier in a reference is used to check for a doc comment.
Implicits do not have an ident, so do not use that to look for a doc
comment.
Also set the context.Context for the renamer.
