# File Ordering Preservation Implementation
## Summary
Implemented `.clasp.json` file ordering preservation to maintain Google Apps Script execution order during sync operations. The system now automatically creates and respects `.clasp.json` configuration to ensure files execute in the correct sequence.
## Problem
Google Apps Script executes files in a specific order (position 0, 1, 2, etc.), which is critical for proper initialization. During sync operations, this ordering could be lost, causing execution failures.
**User Requirement**:
> "we do require all the files to be in a specific order when updating, we should consider keeping a .clasprc file in the root, in the clasp format, which contains the ordering of the files and referencing that when updating the server to keep the files in order"
## Solution
### Three-Component Implementation
1. **`.clasp.json` Generation** - Automatically created during Phase 1 (mirror) with `filePushOrder` array
2. **Order Preservation** - Read and apply during Phase 3 (push) using `reorderFiles` API
3. **Clasp Compatibility** - Standard clasp format for interoperability with Google's official CLI
### File Format
```json
{
"scriptId": "1Y72rigcMUAwRd7bwl3CR57O6ENo5sKTn0xAl2C4HoZys75N5utGfkCUG",
"rootDir": ".",
"filePushOrder": [
"common-js/require.js",
"appsscript.json",
"common-js/__mcp_exec.js",
"common-js/__mcp_exec_error.html",
"common-js/__mcp_exec_success.html",
"common-js/__html_utils.js",
"gas-properties/ConfigManager.js",
"Sidebar.html",
"test-ConfigManager.js",
"tools/SpreadsheetToolHandler.js",
"tools/SearchToolHandler.js",
"tools/ToolRegistry.js",
"tools/ToolBase.js"
]
}
```
### Critical File Ordering
The implementation preserves critical execution order for:
1. **Position 0**: `common-js/require.js` - CommonJS module system (MUST execute first)
2. **Position 1**: `appsscript.json` - Project manifest
3. **Position 2**: `common-js/__mcp_exec.js` - Execution infrastructure (MUST execute second)
4. **Remaining files**: Tools, utilities, UI components in dependency order
## Code Changes
### New Method: `createClaspConfig()`
**Location**: `/Users/jameswiese/src/mcp_gas/src/tools/gitSync.ts:1302-1333`
```typescript
private async createClaspConfig(
scriptId: string,
gasFiles: any[],
basePath: string
): Promise<void> {
// Sort files by position
const sortedFiles = [...gasFiles]
.filter(f => !f.name.startsWith('.git/')) // Exclude git breadcrumbs
.sort((a, b) => (a.position || 0) - (b.position || 0));
// Convert to local file paths (with extensions)
const filePushOrder = sortedFiles.map(file => {
return this.gasPathToLocal(file.name, file.type);
});
// Create .clasp.json structure
const claspConfig = {
scriptId: scriptId,
rootDir: ".",
filePushOrder: filePushOrder
};
// Write .clasp.json to base path
const claspPath = path.join(basePath, '.clasp.json');
await fs.writeFile(claspPath, JSON.stringify(claspConfig, null, 2), 'utf8');
console.error(` š Created .clasp.json with ${filePushOrder.length} files in execution order`);
}
```
**Features**:
- Sorts files by GAS position (0, 1, 2, ...)
- Excludes `.git/` breadcrumb files
- Converts GAS paths to local paths with extensions
- Creates standard clasp-compatible JSON
### Modified: `mirrorAllFilesToLocal()`
**Location**: `/Users/jameswiese/src/mcp_gas/src/tools/gitSync.ts:1121`
```typescript
// Create .clasp.json with file push order to preserve execution sequence
await this.createClaspConfig(scriptId, gasFiles, basePath);
```
**When**: Called at the end of Phase 1 after all files are mirrored
### Modified: `pushAllFilesToGAS()`
**Location**: `/Users/jameswiese/src/mcp_gas/src/tools/gitSync.ts:1197-1217`
```typescript
// Restore file execution order from .clasp.json
const claspPath = path.join(basePath, '.clasp.json');
try {
await fs.access(claspPath);
const claspContent = await fs.readFile(claspPath, 'utf8');
const claspConfig = JSON.parse(claspContent);
if (claspConfig.filePushOrder && Array.isArray(claspConfig.filePushOrder)) {
// Convert local paths to GAS paths
const gasFileOrder = claspConfig.filePushOrder.map((localPath: string) => {
return this.localPathToGas(localPath);
});
console.error(`š Reordering ${gasFileOrder.length} files to match .clasp.json execution order...`);
await gasClient.reorderFiles(scriptId, gasFileOrder, accessToken);
console.error(` ā
File execution order preserved`);
}
} catch (error: any) {
// .clasp.json doesn't exist or couldn't be read - that's OK, order won't be preserved
console.error(` ā¹ļø No .clasp.json found - file order not preserved`);
}
```
**Features**:
- Reads `.clasp.json` from local directory
- Converts local paths back to GAS paths (removes extensions)
- Calls `gasClient.reorderFiles()` to apply ordering
- Graceful fallback if `.clasp.json` missing
## Workflow Integration
### Phase 1: Mirror (Pull from GAS)
1. Fetch all files from GAS with positions
2. Mirror files to local filesystem
3. **NEW**: Create `.clasp.json` with `filePushOrder` array
4. Result: Local directory has all files + `.clasp.json`
### Phase 2: Git Operations
- Unchanged - handles git commits/merges
### Phase 3: Push (Push to GAS)
1. Scan local files for changes
2. Push modified files to GAS
3. **NEW**: Read `.clasp.json` and call `reorderFiles()` to restore order
4. Result: GAS files maintain execution sequence
## API Integration
Uses existing GAS API method:
```typescript
async reorderFiles(
scriptId: string,
fileOrder: string[], // Array of file names in desired order
accessToken?: string
): Promise<GASFile[]>
```
**Example**:
```typescript
const fileOrder = [
"common-js/require",
"appsscript",
"common-js/__mcp_exec",
"tools/ToolBase"
];
await gasClient.reorderFiles(scriptId, fileOrder, accessToken);
```
## Testing Plan
**ā ļø Restart Required**: Claude Code must be restarted before testing to pick up MCP server changes
### Test 1: Fresh Sync
```bash
# Clean start
rm -rf ~/gas-repos/project-{id}
# Sync to create .clasp.json
mcp__gas__local_sync scriptId={id}
# Verify .clasp.json exists
cat ~/gas-repos/project-{id}/.clasp.json
# Verify file order
jq '.filePushOrder[0:3]' ~/gas-repos/project-{id}/.clasp.json
# Expected: ["common-js/require.js", "appsscript.json", "common-js/__mcp_exec.js"]
```
### Test 2: Order Preservation After Push
```bash
# Make local change
echo "// test" >> ~/gas-repos/project-{id}/tools/ToolBase.js
# Push changes
mcp__gas__local_sync scriptId={id}
# Verify file order in GAS
mcp__gas__ls scriptId={id} detailed=true | grep -A 3 "position"
# Expected: Position 0 = common-js/require, Position 2 = common-js/__mcp_exec
```
### Test 3: Clasp Compatibility
```bash
# Try using official clasp CLI
cd ~/gas-repos/project-{id}
clasp push # Should respect filePushOrder
```
## Benefits
1. ā
**Execution Order Preserved** - Files execute in correct sequence (require.js first, etc.)
2. ā
**Clasp Compatible** - Standard format works with Google's official CLI
3. ā
**Automatic** - No manual configuration needed
4. ā
**Bidirectional** - Works for both pull and push operations
5. ā
**Graceful Degradation** - If `.clasp.json` missing, sync still works (order not preserved)
## Console Output
### During Pull (Phase 1)
```
=== PHASE 1: Mirror All Files ===
š„ Mirroring 46 files to ~/gas-repos/project-{id}...

- Complements BUG #1 and BUG #2 fixes from previous implementation
- Enables proper CommonJS module system initialization
## Conclusion
File ordering preservation is now fully implemented using standard `.clasp.json` format. The system automatically maintains Google Apps Script execution order during all sync operations, ensuring proper initialization of the CommonJS module system and preventing execution failures.
