From 4a9fdeebf602b9c43515247357a25e3d8268dadd Mon Sep 17 00:00:00 2001 From: Orien Madgwick <497874+orien@users.noreply.github.com> Date: Thu, 23 Apr 2026 23:39:25 +1000 Subject: [PATCH 1/5] Fix LSP symbol ranges for `textDocument/documentSymbol` and `workspace/symbol` (#5241) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit textDocument/documentSymbol was producing "selectionRange must be contained in range" errors in LSP clients, causing the entire symbol list to be rejected. The root cause was that range was set to the declaration keyword span while selectionRange was set to the identifier span — the identifier starts after the keyword ends. Symbol ranges across both textDocument/documentSymbol and workspace/symbol now cover the full declaration, from the opening keyword to the end of the body. Previously documentSymbol ranges covered only the keyword (class, fun, etc.) and workspaceSymbol ranges covered only the identifier. Two additional compiler quirks required fixes: - ponyc synthesizes create constructors for bare primitives and classes, positioned at the start of the next entity in the file. These were inflating entity ranges into following entities' lines. Fixed by bounding each entity's span to the next sibling's start position and filtering synthesized members from the symbol tree. - type aliases (type Foo is Bar) store the referenced type's definition-site position on the nominal reference node. This was pulling the range start up to Bar's declaration line. Fixed by clamping range.start to the type keyword's position. New integration test suites cover documentSymbol containment, exact ranges, entity kinds, member kinds, cross-file trait filtering, type alias ranges, bare primitive ranges, and workspace/symbol ranges across all member token types. --- .release-notes/lsp-symbol-range.md | 5 + tools/pony-lsp/ast_source_span.pony | 113 +++ tools/pony-lsp/symbols.pony | 112 ++- .../_document_symbol_integration_tests.pony | 648 ++++++++++++++++++ .../_workspace_symbol_integration_tests.pony | 263 +++++-- tools/pony-lsp/test/main.pony | 1 + .../document_symbol/_ds_containment.pony | 19 + .../document_symbol/_ds_ent_interface.pony | 23 + .../workspace/document_symbol/_ds_impl.pony | 13 + .../document_symbol/_ds_member_host.pony | 24 + .../workspace/document_symbol/_ds_trait.pony | 27 + .../document_symbol/document_symbol.pony | 24 + .../workspace_symbol/_ws_sym_host.pony | 21 + .../workspace_symbol/workspace_symbol.pony | 9 + .../pony-lsp/workspace/selection_ranges.pony | 84 +-- .../pony-lsp/workspace/workspace_manager.pony | 4 +- 16 files changed, 1223 insertions(+), 167 deletions(-) create mode 100644 .release-notes/lsp-symbol-range.md create mode 100644 tools/pony-lsp/ast_source_span.pony create mode 100644 tools/pony-lsp/test/_document_symbol_integration_tests.pony create mode 100644 tools/pony-lsp/test/workspace/document_symbol/_ds_containment.pony create mode 100644 tools/pony-lsp/test/workspace/document_symbol/_ds_ent_interface.pony create mode 100644 tools/pony-lsp/test/workspace/document_symbol/_ds_impl.pony create mode 100644 tools/pony-lsp/test/workspace/document_symbol/_ds_member_host.pony create mode 100644 tools/pony-lsp/test/workspace/document_symbol/_ds_trait.pony create mode 100644 tools/pony-lsp/test/workspace/document_symbol/document_symbol.pony create mode 100644 tools/pony-lsp/test/workspace/workspace_symbol/_ws_sym_host.pony create mode 100644 tools/pony-lsp/test/workspace/workspace_symbol/workspace_symbol.pony diff --git a/.release-notes/lsp-symbol-range.md b/.release-notes/lsp-symbol-range.md new file mode 100644 index 000000000..3d63bbb56 --- /dev/null +++ b/.release-notes/lsp-symbol-range.md @@ -0,0 +1,5 @@ +## Fix LSP symbol ranges + +LSP clients that use `textDocument/documentSymbol` (the outline/breadcrumb view in most editors) could produce a "selectionRange must be contained in range" error, causing the entire symbol list to be rejected.
