Muir Manders 49ba83114e internal/lsp: improve composite literal completion ... 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 Fixes golang/go#29153 Change-Id: If8cf678cbd743a970f52893fcf4a9b83ea06d7e9 GitHub-Last-Rev: f385705cc05eb98132e20561451dbb8c39b68519 GitHub-Pull-Request: golang/tools#86 Reviewed-on: https://go-review.googlesource.com/c/tools/+/173099 Run-TryBot: Rebecca Stambler <rstambler@golang.org> Reviewed-by: Rebecca Stambler <rstambler@golang.org>		2019-04-23 22:28:03 +00:00
