Sometimes the prefix of the thing you want to complete is a keyword. For example: variance := 123 fmt.Println(var<>) In this case the parser produces an *ast.BadExpr which breaks completion. We now repair this BadExpr by replacing it with an *ast.Ident named "var". We also repair empty decls using a similar approach. This fixes cases like: var typeName string type<> // want to complete to "typeName" We also fix accidental keywords in selectors, such as: foo.var<> The parser produces a phantom "_" in place of the keyword, so we swap it back for an *ast.Ident named "var". In general, though, accidental keywords wreak havoc on the AST so we can only do so much. There are still many cases where a keyword prefix breaks completion. Perhaps in the future the parser can be cursor/in-progress-edit aware and turn accidental keywords into identifiers. Fixes golang/go#34332. PS I tweaked nodeContains() to include n.End() to fix a test failure against tip related to a change to go/parser. When a syntax error is present, an *ast.BlockStmt's End() is now set to the block's final statement's End() (earlier than what it used to be). In order for the cursor pos to test "inside" the block in this case I had to relax the End() comparison.
