|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1238: Macro queries r=edwin0cheng a=matklad In https://github.com/rust-analyzer/rust-analyzer/pull/1231, I've added aggressive clean up of `ast_id_to_node` query. The result of this query is a `SyntaxTree`, and we don't want to retain syntax trees in memory unless absolutely necessary. Moreover, `SyntaxTree` has identity equality semantics, meaning that we'll get a diffferent syntax tree for a file after every reparse. That means that `ast_id_to_node` query should not genereally be used in HIR, unless it is behind some kind of salsa firewall, like the `raw` module of name resoulution. However, that PR resulted in the abysmal performance: turns out we were using ast_id_to_node quite heavily in hir when expanding macros! So this PR installs the more incremental-friendly query structure: * converting source to token tree is now a query; changing source without affecting token-trees will now preserve macro expansions * expand macro (tt -> tt) is now a query as well, so we cache macro expansions *before* parsing them into item lists or expressions, which is nice: we can cache expansion without knowing the calling context! r? @edwin0cheng Co-authored-by: Aleksey Kladov <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | Currently, when expanding macros, we look at the source code directly (we invoke ast_id_to_node query via to_node method). This is less then ideal, because it make us re-expand macros after every source change. This commit establishes a salsa-firewall: a query to get macro call's token tree. Unlike the syntax tree, token tree changes only if we actually modify the macro itself.

The reason for this was that the search for an expression was slightly left-biased: When on the edge between two tokens, it first looked at all ancestors of the left token and then of the right token. Instead merge the ancestors in ascending order, so that we get the smaller of the two possible expressions. This might seem rather inconsequential, but emacs-lsp's sideline requests hover for the beginning of each word in the current line, so it tends to hit this a lot :smile: Actually, as I think about this now, another solution might be just making hover right-biased, since if I'm hovering a certain character I really mean that character and not the one to its left...
