Changes: - Created src/types.ts with AnyNode union of all 38+ node types - Updated css-node-base.ts traversal methods to return AnyNode - Updated walk.ts callback signatures to use AnyNode - Exported AnyNode from index.ts for public use Benefits: - TypeScript now enforces type narrowing with instanceof - IDE autocomplete works after type narrowing - No more unsafe access to type-specific properties - Zero runtime overhead (unions are compile-time only) Breaking change: Tests and user code must use instanceof checks or type assertions to access type-specific properties like `values`, `name`, `property`, etc. Example: const rule = root.first_child if (rule instanceof StyleRuleNode) { console.log(rule.selector_list) // ✓ type-safe } This completes the migration to type-specific node classes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/anplusb-parser.test.ts | 6 +- src/at-rule-prelude-parser.test.ts | 100 ++--

Bart Veneman Date: Sat, 29 Nov 2025 23:34:50 +0100 Subject: [PATCH 29/31] Fix type-specific node creation and property implementations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit completes the migration to type-specific traversal by ensuring all nodes are created with the correct types and have necessary properties. Key changes: 1. Factory method usage: - Updated parser.parse() to use CSSNode.from() factory instead of direct constructor - Added create_node_wrapper override to all 30+ type-specific node classes - Ensures all traversal returns properly typed nodes (DeclarationNode, ValueFunctionNode, etc.) 2. Node property fixes: - Fixed DeclarationNode.value getter to return string (removed incorrect dimension parsing) - Added is_vendor_prefixed getter to SelectorPseudoClassNode and SelectorPseudoElementNode - Added default is_vendor_prefixed implementation to CSSNode base class - Added comment stripping to prelude node value/name getters 3. Test updates: - Added type assertions for ValueDimensionNode and ValueFunctionNode in value-parser.test.ts - All 586 tests now passing The tree structure now properly returns type-specific nodes through the AnyNode union type, enabling IDE autocomplete and type-safe property access. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/column-tracking.test.ts | 3 +- src/css-node-base.ts | 11 + src/nodes/at-rule-node.ts | 9 +- src/nodes/block-node.ts | 9 +- src/nodes/comment-node.ts | 9 +- src/nodes/declaration-node.ts | 22 +- src/nodes/prelude-container-supports-nodes.ts | 43 +- src/nodes/prelude-import-nodes.ts | 26 +- src/nodes/prelude-media-nodes.ts | 28 +- src/nodes/selector-attribute-node.ts | 9 +- src/nodes/selector-node.ts | 9 +- src/nodes/selector-nodes-named.ts | 21 +- src/nodes/selector-nodes-simple.ts | 33 +- src/nodes/selector-nth-nodes.ts | 15 +- src/nodes/selector-pseudo-nodes.ts | 36 +- src/nodes/style-rule-node.ts | 9 +- src/nodes/stylesheet-node.ts | 9 +- src/nodes/value-nodes.ts | 45 +- src/parse.test.ts | 11 +- src/parser-options.test.ts | 17 +- src/parser.test.ts | 409 +++++++++--------- src/parser.ts | 2 +- src/selector-parser.test.ts | 13 +- src/stylerule-structure.test.ts | 3 +- src/value-parser.test.ts | 80 ++-- src/walk.test.ts | 3 +- 26 files changed, 545 insertions(+), 339 deletions(-) diff --git a/src/column-tracking.test.ts b/src/column-tracking.test.ts index 4b3f5f9..c4e638d 100644 --- a/src/column-tracking.test.ts +++ b/src/column-tracking.test.ts @@ -1,6 +1,7 @@ import { describe, test, expect } from 'vitest' import { parse } from './parse' import { NODE_STYLE_RULE, NODE_DECLARATION, NODE_AT_RULE, NODE_SELECTOR_LIST } from './parser' +import { AtRuleNode } from './css-node' describe('Column Tracking', () => { test('should track column for single-line CSS', () => { @@ -69,7 +70,7 @@ describe('Column Tracking', () => { expect(atRule.column).toBe(1) // Get the block, then find the nested style rule - const block = atRule.block! + const block = (atRule as AtRuleNode).block! let nestedRule = block.first_child while (nestedRule && nestedRule.type !== NODE_STYLE_RULE) { nestedRule = nestedRule.next_sibling diff --git a/src/css-node-base.ts b/src/css-node-base.ts index d34c883..9664715 100644 --- a/src/css-node-base.ts +++ b/src/css-node-base.ts @@ -222,4 +222,15 @@ export abstract class CSSNode { return false } + // Check if this node has a vendor prefix + // Default: false.

Changes: 1. Updated 19 forward-declared type aliases from CSSNode to AnyNode: - Core: ImportComponentNode, MediaComponentNode, PreludeComponentNode, SelectorComponentNode, ValueNode - Block types: PreludeNode, BlockNode, DeclarationNode, StyleRuleNode, AtRuleNode, CommentNode, SelectorListNode 2. Updated children getter overrides to return AnyNode[] instead of CSSNode[] in 7 files (at-rule, block, prelude-import, prelude-media, selector-node, style-rule, stylesheet, value-nodes) 3. Added type assertions in 2 locations: - CSSNode.from() default case (fallback for unknown node types) - Parser.parse() return (ensures StylesheetNode type) Result: Zero TypeScript errors, all 586 tests passing This aligns the type system with the actual runtime behavior where all node types are part of the AnyNode union, enabling proper type inference throughout tree traversal. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/css-node-base.ts | 2 +- src/css-node.ts | 7 ++++--- src/nodes/at-rule-node.ts | 7 ++++--- src/nodes/block-node.ts | 11 ++++++----- src/nodes/comment-node.ts | 3 ++- src/nodes/declaration-node.ts | 5 +++-- src/nodes/prelude-container-supports-nodes.ts | 13 +++++++------ src/nodes/prelude-import-nodes.ts | 11 ++++++----- src/nodes/prelude-media-nodes.ts | 11 ++++++----- src/nodes/selector-attribute-node.ts | 3 ++- src/nodes/selector-node.ts | 5 +++-- src/nodes/selector-nodes-named.ts | 7 ++++--- src/nodes/selector-nodes-simple.ts | 13 +++++++------ src/nodes/selector-nth-nodes.ts | 7 ++++--- src/nodes/selector-pseudo-nodes.ts | 7 ++++--- src/nodes/style-rule-node.ts | 7 ++++--- src/nodes/stylesheet-node.ts | 11 ++++++----- src/nodes/value-nodes.ts | 17 +++++++++-------- src/parser.ts | 6 +++--- 19 files changed, 85 insertions(+), 68 deletions(-) diff --git a/src/css-node-base.ts b/src/css-node-base.ts index 9664715..5097af7 100644 --- a/src/css-node-base.ts +++ b/src/css-node-base.ts @@ -164,7 +164,7 @@ export abstract class CSSNode { } // Helper to create node wrappers -
