@copilot расскажу подробнее про дедупликацию. Одна строка может содержать несколько токенов языка запросов. Как выглядит результииующие данные? Точно ли токен строки не располагается поверх токенов ключевых слов запросов? |

@copilot В плане типов токенов ориентируйся вот сюда: https://github.com/1c-syntax/1c-syntax/blob/master/1c-query.YAML-tmLanguage Если есть вопросы в мапинге - задавай. |
The previous implementation had an issue where BSL STRING tokens would overlap with SDBL tokens because deduplication only removes exact duplicates (same line, start, length, type, and modifiers). Changes: - Properly identify BSL STRING tokens that contain SDBL tokens - Remove those STRING tokens from the entries list - Split STRING tokens around SDBL tokens, adding only non-query parts - Add SDBL tokens to highlight query language elements This follows the pattern from BSLHighlighter in sonar-bsl-plugin-community where overlapping string tokens are marked as inactive and split into parts.

Вы правы! В предыдущей реализации была проблема с наложением токенов. Проблема: Дедупликация через Исправление в коммите caac2d9:
Теперь результат содержит: части строк (без запроса) + токены SDBL (ключевые слова, типы метаданных, параметры и т.д.) без наложений. |
Based on feedback to use the 1c-syntax/1c-query.YAML-tmLanguage as a reference: Changes: - Add SemanticTokenTypes.Type to legend for metadata types and virtual tables - Add SemanticTokenModifiers.DefaultLibrary to legend for built-in constructs - Map SDBL functions to Function type (not Type) per YAML support.function.sdbl - Apply defaultLibrary modifier to built-in functions, metadata types, virtual tables - Metadata types/virtual tables remain as Type per YAML support.type.sdbl - All token mappings now align with YAML tmLanguage categories: * keyword.control.sdbl → Keyword * support.function.sdbl → Function + defaultLibrary * support.type.sdbl → Type + defaultLibrary * constant.language.sdbl → Keyword * constant.numeric.sdbl → Number * variable.parameter.sdbl → Parameter * comment.line.sdbl → Comment * string.quoted.sdbl → String Co-authored-by: nixel2007 <[email protected]>

Pull request overview
This PR adds comprehensive semantic token highlighting support for SDBL (1C query language) embedded within BSL string literals. The implementation uses a dual-layer approach combining lexical token processing with AST-based semantic analysis to provide accurate syntax highlighting for query language constructs.
Key Changes:
- Added 5 new semantic token types (Type, Property, Class, Enum, EnumMember) and 2 new modifiers (DefaultLibrary, Declaration) to the legend
- Implemented SDBL token processing that identifies query strings, splits them around SDBL tokens, and adds semantic highlighting for keywords, functions, metadata references, table aliases, field names, and parameters
- Added comprehensive test suite with 26 tests covering BSL and SDBL token highlighting scenarios

There was a problem hiding this comment.
The inline comment incorrectly describes this token type. SemanticTokenTypes.Type is not "for general type references" - it's a standard LSP token type for type names. The comment should be removed or updated to accurately describe its usage, or if this token type is not actually used in the implementation, consider removing it from the legend.

SemanticTokenTypes.Type is added to the legend but is never used in the implementation. Adding unused token types to the legend increases client-side memory usage and can confuse developers about what token types are actually supported. Either implement usage of this token type or remove it from the legend.

There was a problem hiding this comment.
The code for collecting SDBL tokens by line (lines 621-630) is duplicated in both collectStringsWithSdblTokens and addSdblTokens methods (lines 675-684). This duplicated logic should be extracted into a separate helper method to improve maintainability and avoid potential inconsistencies if the logic needs to be changed in the future.

The comment states that the merged token length is the sum of both comment lines (51 chars), but this calculation doesn't account for the newline character between the lines. When multiline tokens are merged, they typically include the text across multiple lines including line breaks. This comment should clarify whether the length includes newline characters or explain the actual calculation method used by the merger.

There was a problem hiding this comment.
The comment "Context-dependent, treat as variable for now" suggests this is a temporary or incomplete implementation. If this is intentional and correct behavior, the comment should be clarified. If it's a known limitation, it should be documented more clearly or tracked as a TODO.
| // Single identifier - could be alias or field | |
| // Context-dependent, treat as variable for now | |
| // Single identifier: in SDBL it may represent either a table alias or a field name. | |
| // We intentionally highlight such ambiguous identifiers as "variable" for now, | |
| // because distinguishing alias vs. field here would require deeper symbol resolution | |
| // that is not performed in this visitor. |

| var emptyRef = ctx.emptyFer; // Note: grammar has typo "emptyFer" instead of "emptyRef" |
There was a problem hiding this comment.
The variable name 'emptyFer' appears to be a typo that mirrors a typo in the grammar. While the comment acknowledges this, it would be better to use the correct spelling 'emptyRef' in the code and add the comment explaining the grammar typo, rather than propagating the typo into the codebase.

| SemanticTokenTypes.Class, // Added for SDBL metadata types (Справочник, РегистрСведений, etc.) |
There was a problem hiding this comment.
The inline comment is misleading. SemanticTokenTypes.Class is not "for SDBL metadata types" - metadata types like Справочник and РегистрСведений are actually mapped to Namespace type (as seen in line 798 of SemanticTokensProvider.java). The Class type is used for metadata object names like Контрагенты or Валюты. The comment should be corrected to reflect the actual usage.
| SemanticTokenTypes.Class, // Added for SDBL metadata types (Справочник, РегистрСведений, etc.) | |

| } |
There was a problem hiding this comment.
When there are more than 2 identifiers in a column reference (e.g., A.B.C), only the first and last identifiers are handled. Middle identifiers are not assigned any semantic token type. This means in a three-part reference like "Table.Subtable.Field", the "Subtable" part would not receive proper semantic highlighting. Consider handling all intermediate identifiers appropriately.

There was a problem hiding this comment.
The method assumes that the context is single-line (see comment on line 1258), but does not validate this assumption. If the start and stop tokens are on different lines, the calculated length will be incorrect and the resulting Range will be invalid (start and end positions will be on the same line but with incorrect character positions). Add validation to handle multi-line contexts or document that this method should only be used for single-line contexts.

| int start = startToken.getCharPositionInLine(); | |
| // Calculate length from start of first token to end of last token | |

| // Calculate end position from the stop token, supporting multi-line contexts | |

The comment says "6) Build delta-encoded data" but this is the second step labeled "6)" in the sequence (the previous step at line 241 is also labeled "6)"). This appears to be a copy-paste error. The comment should be updated to "7) Build delta-encoded data" to maintain correct numbering in the sequence.

Fixed several issues identified in automated code review: 1. Fixed comment numbering: Changed "6) Build delta-encoded data" to "7)" as it's the 7th step 2. Improved comment accuracy for SemanticTokenTypes.Type - clarified it's for type names (identifiers of types) 3. Updated comment for SemanticTokenTypes.Class - clarified it's for metadata object names (e.g., Контрагенты, Валюты), not metadata types 4. Improved ambiguous identifier comment in visitColumn - explained single identifiers are intentionally treated as variables because distinguishing requires symbol resolution not performed in visitor 5. Clarified newline handling comment in test - explained that merged multiline token length is sum of lines without newlines 6. Better explained emptyRef variable name - matches grammar field 'emptyFer' (typo in grammar for 'emptyRef') Note: Did NOT remove SemanticTokenTypes.Type from legend as it may be used by future extensions Note: Did NOT extract duplicate SDBL token collection code as contexts differ (collection vs processing) Note: Did NOT change multi-line range handling as SDBL contexts are always single-line Note: Did NOT change middle identifier handling as SDBL doesn't support 3-part column references All changes improve code documentation and clarity without changing functionality.
