span.NewRange now accepts a *token.File and two token.Pos. It is the caller's responsibility to look up the File in the FileSet, if necessary (it usually isn't), and to ensure the Pos values are valid. Ditto NewMappedRange. This reduces the creep of Snapshot into functions that have no need to know about it. Also the bug.Report call in NewRange has been pushed up into the caller and logically eliminated in all but one case. I think we should aim for the invariant that functions that operate on a single file should accept a *token.File, not a FileSet; only functions that operate on sets of files (e.g. type checking, analysis) should use a FileSet. This is not always possible: some public functions accept a FileSet only to re-lookup a single file already known to the caller; if necessary we could provide token.File variants of these. This may ultimately allow us to create a new FileSet per call to the parser, so that Files and FileSets are in 1:1 correspondance and there is no global FileSet. (It currently grows without bound, on the order of kilobytes per keystroke.) FileSets containing multiple files, needed when we interact with the type checker and analysis, may be temporarily synthesized on demand from a set of Files, analogous to mmap'ing a few files into a blank address space. Also: - replace File.Position(pos).Line by File.Line(pos) - replace pos == token.NoPos by pos.IsValid() - avoid fishy token.Pos conversions in link.go - other minor simplifications Change-Id: Ia3119e0ac7e193801fbafa81c8f48acfa14e9ae4 Reviewed-on: https://go-review.googlesource.com/c/tools/+/409935 Auto-Submit: Alan Donovan <adonovan@google.com> Reviewed-by: Robert Findley <rfindley@google.com> Run-TryBot: Alan Donovan <adonovan@google.com> gopls-CI: kokoro <noreply+kokoro@google.com> TryBot-Result: Gopher Robot <gobot@golang.org> |
