SpreadJS Advanced API

Raw Objects

Access the underlying SpreadJS objects:

typescript
const rawWorkbook = workbook.originalWorkbook;  // GC.Spread.Sheets.Workbook
const rawSheet = workbook.getActiveSheet().originalSheet;  // GC.Spread.Sheets.Worksheet
// GC.Spread.Sheets.* namespace available for enums, constructors, etc.

API Reference Structure

The type definitions in api-reference.ts are organized as nested modules under GC:

code
GC
├── Data              (line ~2)      - DataManager, Table, View, data binding
├── Pivot             (line ~3978)   - Pivot table types and enums
└── Spread
    ├── CalcEngine    (line ~4704)   - Formula engine, custom functions
    ├── Commands      (line ~5179)   - Command system, key bindings
    ├── Common        (line ~5424)   - Shared interfaces, culture info
    ├── Formatter     (line ~5949)   - Number/date formatting
    ├── Pivot         (line ~6225)   - Pivot table implementation
    ├── Report        (line ~11188)  - Report templates
    ├── Sheets        (line ~12641)  - Core spreadsheet (Workbook, Worksheet, Range, Style, etc.)
    └── Slicers       (line ~60687)  - Table/pivot slicers

Searching the API

bash
# Find a class and its methods
grep -n "export class Worksheet" api-reference.ts -A 200 | head -100

# Search for method names
grep -n "setSparkline\|getSparkline" api-reference.ts

# Find enums and their values
grep -n "export enum" api-reference.ts | head -30
grep -n "enum ChartType" api-reference.ts -A 50

# Search by keyword
grep -in "outline\|group" api-reference.ts | head -30

# Find interfaces for options/config objects
grep -n "export interface.*Options\|export type.*Options" api-reference.ts

Creating Reusable Skills

When building a skill with helper functions, use the loader pattern:

1. Create loader.js

javascript
// /files/skills/my-skill/loader.js
const _loadMySkill = new Function('GC', 'workbook', `
  function myHelper(sheet, arg1, arg2) {
    const rawSheet = sheet.originalSheet;
    // Use GC.Spread.Sheets.* APIs here
    return rawSheet.someMethod(arg1, arg2);
  }
  
  function anotherHelper(sheet, arg) {
    // ...
  }
  
  return { myHelper, anotherHelper };
`);
Object.assign(store, _loadMySkill(GC, workbook));

Why new Function()? Regular functions defined in eval() don't persist. The Function constructor creates functions that can be assigned to store.

Note: Escape backslashes in regex inside the template string: \\d+ not \d+

2. Load and Use

bash
# Step 1: Read loader into store (bash_command)
cat /files/skills/my-skill/loader.js
# Set to_store: "my_skill_loader"
typescript
// Step 2: Initialize (execute_code) - only needed once per session
eval(store.my_skill_loader);

// Step 3: Use the helpers
store.myHelper(sheet, "arg1", "arg2");

3. Document in SKILL.md

markdown
## Loading
1. bash: `cat /files/skills/my-skill/loader.js` → store
2. execute_code: `eval(store.my_skill_loader)`
3. Use: `store.myHelper(sheet, ...)`

## API
**myHelper(sheet, arg1, arg2)** - Description of what it does

Cautions

  1. •Raw API changes may bypass dirty cell tracking (won't appear in review diff)
  2. •Prefer standard workbook/sheet API when available
  3. •Always search api-reference.ts for exact method signatures
