Adding CLAUDE.md with task information for AI processing. This file will be removed when the task is complete. Issue: #148
This change adds automatic tokenization of punctuation and math symbols
during parsing, making them separate references in Links Notation.
Key features:
- Punctuation (`,`, `.`, `;`, `!`, `?`) is tokenized when following alphanumeric characters
- Math symbols (`+`, `-`, `*`, `/`, `=`, etc.) are tokenized only when between digits
- Hyphenated words (e.g., "Jean-Luc", "conan-center-index") are preserved
- Quoted strings preserve their content
- Base64 strings with `=` padding are preserved
- Backward compatible: use `tokenizeSymbols: false` to disable
New APIs:
- JS: `Parser({ tokenizeSymbols: boolean })`, `FormatOptions({ compactSymbols: boolean })`
- Rust: `Tokenizer`, `parse_lino_raw()`, `format_links_compact()`
- Python: `Parser(tokenize_symbols=bool)`, `Tokenizer` class
Example:
- Input: `1,2,3` → Values: `["1", ",", "2", ",", "3"]`
- Input: `1+1` → Values: `["1", "+", "1"]`
- Input: `Jean-Luc` → Values: `["Jean-Luc"]` (preserved)
- Input: `"1,2,3"` → Values: `["1,2,3"]` (quoted preserved)

Summary
This PR implements automatic tokenization of punctuation and math symbols during parsing, as requested in issue #148. The parser now separates these symbols from adjacent characters, making them individual references in Links Notation.
Key Features
Punctuation tokenization: Symbols like
,,.,;,!,?are separated from words1, 2 and 3→["1", ",", "2", "and", "3"]hello, world→["hello", ",", "world"]Math symbol tokenization: Symbols like
+,-,*,/,=are separated only when between digits1+1→["1", "+", "1"]10-20→["10", "-", "20"]Hyphenated words preserved: Words with hyphens between letters are kept intact
Jean-Luc Picard→["Jean-Luc", "Picard"]conan-center-index→["conan-center-index"]Quoted strings preserved: Content inside quotes is not tokenized
"1,2,3"→["1,2,3"]"hello, world"→["hello, world"]Base64 preserved: Strings like
bmFtZQ==are kept intactCompact formatting: New option to restore human-readable output without spaces around symbols
Backward Compatibility
Set
tokenizeSymbols: false(JS/Python) or useparse_lino_raw()(Rust) to disable tokenization.Test Plan
Version Bump
Updated all implementations to version 0.13.0.
