v1.2 Features Guide

Tables, modular documents, and enterprise-grade security in OmniScript v1.2.0.

@table Blocks

NEW

Create beautiful tables using familiar Markdown syntax with advanced features.

Basic Table

basic-table.osf
@table {
  | Product | Price | Stock |
  | --- | --- | --- |
  | Widget | $99 | 45 |
  | Gadget | $149 | 23 |
  | Doohickey | $79 | 67 |
}

With Caption and Styling

styled-table.osf
@table {
  caption: "Q4 Sales Report";
  style: "bordered";
  
  | Region | Revenue | Growth |
  | --- | --- | --- |
  | North | $1.2M | +18% |
  | South | $880K | +17% |
  | East | $1.5M | +24% |
}

With Column Alignment

aligned-table.osf
@table {
  caption: "Product Inventory";
  style: "striped";
  alignment: ["left", "right", "center"];
  
  | Product | Price | Status |
  | --- | --- | --- |
  | Widget Pro | $129 | ✓ In Stock |
  | Gadget Max | $199 | ⚠ Low |
  | Thing Mini | $49 | ✓ In Stock |
}

Table Properties

caption: Optional table title displayed above the table
style: "bordered", "striped", or "minimal"
alignment: Array of "left", "center", or "right"

✨ Features

✅ Markdown pipe syntax (familiar and easy)
✅ Optional captions for context
✅ Three built-in styles
✅ Per-column alignment
✅ XSS protection (automatic HTML escaping)
✅ Round-trip serialization

@include Directive

NEW

Build modular documents by composing sections from multiple files.

Basic Include

main.osf
@meta {
  title: "Annual Report";
  date: "2025-10-16";
}

@include { path: "./sections/executive-summary.osf"; }
@include { path: "./sections/financial-data.osf"; }
@include { path: "./sections/recommendations.osf"; }

Nested Includes

Included files can themselves contain @include directives (up to 10 levels deep).

sections/executive-summary.osf
// sections/executive-summary.osf
@doc {
  # Executive Summary
  
  Our Q4 performance exceeded expectations.
}

@include { path: "./subsections/highlights.osf"; }

Include Properties

path: Relative path to the .osf file to include
Depth limit: Maximum 10 levels of nesting
Circular detection: Prevents infinite loops

🔒 Security Features

✅ Path traversal protection (blocks ../../../etc/passwd)
✅ Circular reference detection
✅ Depth limit prevents stack overflow
✅ Only allows relative paths within base directory

Security Grade A+

ENTERPRISE

Comprehensive security improvements achieve enterprise-grade protection.

Path Traversal Protection

Prevents directory escape attacks:

security-example.osf
// ❌ BLOCKED
@include {
  path: "../../../../etc/passwd";
}

// ✅ ALLOWED
@include {
  path: "./sections/intro.osf";
}

ReDoS Prevention

Bounded regex quantifiers prevent catastrophic backtracking.

✅ Uses \s{0,20} instead of \s*
✅ Prevents exponential runtime attacks
✅ All regexes audited and secured

Input Validation

Strict validation at every layer:

✅ Table column count consistency
✅ Alignment array validation
✅ Number parsing edge cases
✅ Helpful error messages

Defense-in-Depth

Multi-layer security architecture:

✅ Parser-level validation
✅ Renderer-level sanitization
✅ Runtime input validation
✅ XSS protection in HTML output

19 Security Tests

Comprehensive test suite verifies all security protections:

• Path traversal (5 tests)
• Table validation (6 tests)
• ReDoS prevention (3 tests)

• Number parsing (3 tests)
• Base path validation (2 tests)
• All passing ✅

Security Grade

Test Breakdown

Parser: 83 tests (parsing, serialization, validation)
CLI: 47 tests (commands, rendering, formatting)
Converters: 73 tests (PDF, DOCX, PPTX, XLSX)
Security: 19 tests (path traversal, ReDoS, validation)

Migration from v1.1

✅ Zero Breaking Changes

v1.2.0 is 100% backward compatible with v1.1. All existing documents work without modification.

New Features (Optional)

Start using new features at your own pace:

migration-example.osf
// Your existing v1.1 documents work as-is
@doc {
  # My Document
  Content here...
}

// Add @table when you need tables
@table {
  | A | B |
  | --- | --- |
  | 1 | 2 |
}

// Add @include when you want modular docs
@include { path: "./sections/extra.osf"; }

Stricter Validation

v1.2.0 includes stricter validation that may catch errors in malformed documents:

• Table column counts must match header
• Alignment values must be "left", "center", or "right"
• Number parsing is more strict

These changes improve robustness but may require fixing previously-ignored errors.
