When the value of a composite literal key/value pair was unparsable,
you were getting completions for the composite literal keys instead of
values. For example "struct { foo int }{foo: []<>" was completing to
the field name "foo". This was because the leaf ast.Node at the cursor
was the composite literal itself, and our go-back-one-character logic
was not happening because the preceding character's node
was *ast.BadExpr, not *ast.Ident. Fix by always generating the ast
path for the character before the cursor's position. I couldn't find
any cases where this broke completion.
I also added expected type detection for the following composite
literal cases:
- array/slice literals
- struct literals (both implicit and explicit field names)
- map keys and values

- show signature for function calls whose function expression is not
an object (e.g. the second call in foo()()). since the function name
is not available, we use the generic "func"
- only provide signature help when the position is on or within the
call expression parens. this is consistent with the one other lsp
server i tried (java). this improves the gopls experience in emacs
where lsp-mode is constantly calling "hover" and
"signatureHelp" ("hover" should be preferred unless you are inside
the function params list)
- use the entire signature type string as the label since that includes
the return values, which are useful to see
- don't qualify the function name with its package. it looks funny to
see "bytes.Cap()" as the help when you are in a call
to (*bytes.Buffer).Cap(). it could be useful to include invocant
type info, but leave it out for now since signature help is meant to
focus on the function parameters.
- don't turn variadic args "foo ...int" into "foo []int" for the
parameter information (i.e. maintain it as "foo ...int")
- when determining active parameter, count the space before a
parameter name as being part of that parameter (e.g. the space
before "b" in "func(a int, b int)")
- handle variadic params when determining the active param (i.e.
highlight "foo(a int, *b ...string*)" on signature help for final
param in `foo(123, "a", "b", "c")`
- don't generate an extra space in formatParams() for unnamed
arguments
I also tweaked the signatureHelp server log message to include the
error message itself, and populated the server's logger in lsp_test.go
to aid in development.
