docs: Comprehensively document lazy field access feature

0xrinegade · claude · 0xrinegade · commit 0eeb16cb87ea · 2025-11-09T07:04:57.000+03:00
Added extensive documentation for the new lazy/recursive field access feature across all relevant documentation files and created a comprehensive demo script. **Documentation Updates:** - Main README.md: Added lazy field access to Key Features and AI & Automation sections - crates/ovsm/README.md: Added prominent section with examples and benefits - docs/pages/ovsm-language.html: Added to feature grid, new dedicated section, and comprehensive example - examples/ovsm_scripts/lazy_field_access_demo.ovsm: 7 comprehensive examples (210 lines) **Changes:** 1. Landing Page (ovsm-language.html): - Added to feature grid as main selling point - Created dedicated highlighted section with gradient background - Added real-world MCP example with before/after comparison - Updated Objects table entry to mention lazy field access 2. OVSM Crate README (crates/ovsm/README.md): - Added prominent NEW! section at top of Features - Included how it works, benefits, and example - Added to Core Language feature list - Created dedicated "Real-World MCP Usage" example section 3. Main README (README.md): - Added to Key Features list with emoji and example - Added to AI & Automation features table - Positioned as a key differentiator 4. Demo Script (lazy_field_access_demo.ovsm): - Example 1: Simple nested access - Example 2: Real-world MCP token response - Example 3: Deep nesting (6 levels) - Example 4: Missing fields (graceful handling) - Example 5: Field name collision (precedence) - Example 6: Performance (direct vs lazy) - Example 7: Arrays not searched (only objects) - All examples tested and working ✅ **Marketing Positioning:** Feature is now prominently displayed as one of OVSM's main selling points, with clear before/after comparisons showing the dramatic simplification it provides. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

 ## ✨ Features
 
+### 🧠 Lazy Field Access (NEW!)
+
+**Automatically searches nested objects** - No need to know exact structure!
+
+```lisp
+;; MCP response with nested metadata
+(define response {
+  :supply 999859804306166700
+  :metadata {
+    :name "OSVM.AI"
+    :symbol "OVSM"
+  }
+})
+
+;; ❌ OLD WAY: Verbose nested access
+(define name (get (get response "metadata") "name"))
+
+;; ✅ NEW WAY: Lazy field access
+(define name (get response "name"))  ;; Finds metadata.name automatically! ✨
+(define symbol (get response "symbol"))  ;; Finds metadata.symbol automatically!
+```
+
+**How it works:**
+1. Tries direct access first (O(1) for top-level fields)
+2. If not found, recursively searches nested objects (depth-first)
+3. Returns first match found (deterministic, predictable)
+4. Works with arbitrary nesting depth
+5. Returns `null` if field doesn't exist anywhere
+
+**Benefits:**
+- ✅ Simpler code - write `(get obj "field")` instead of `(get (get obj "nested") "field")`
+- ✅ More forgiving - don't need to know exact API structure
+- ✅ Backward compatible - explicit nested access still works
+- ✅ Zero performance overhead for direct access
