Stampignore

The .stampignore file tells LogicStamp Context which files to exclude from context compilation. You can use it to exclude any files you don't want included in your context bundles.

Overview

When you run stamp context or stamp context style (equivalent to stamp context --include-style), LogicStamp automatically reads .stampignore and excludes any files listed in it. This happens before processing, so excluded files are never analyzed or included in context bundles.

All context compilation commands respect .stampignore:

  • stamp context - Standard context compilation
  • stamp context style - Context compilation with style metadata (equivalent to stamp context --include-style)
  • stamp context --include-style - Alternative syntax for style metadata extraction

Use cases:

  • Exclude large files that aren't needed for context
  • Skip test fixtures or mock data files
  • Ignore generated or temporary files
  • Exclude any files you don't want in context bundles

File Format

.stampignore uses JSON format and must be placed in your project root directory.

Basic Structure

{ "ignore": [ "path/to/file.ts", "another/file.js" ] }

Example

{ "ignore": [ "src/config/secrets.ts", "src/api/keys.ts", "lib/credentials.js", "**/*.secret.ts", "**/secrets/**" ] }

Path Rules

Relative Paths

All paths in .stampignore must be relative to the project root:

  • ✅ Project-relative paths: src/config/secrets.ts, lib/keys.js
  • ❌ Absolute paths not supported: /home/user/project/src/config.ts, C:\Users\...\src\config.ts
  • ❌ User-specific paths not included: No home directory paths, no absolute paths outside project
{ "ignore": [ "src/config.ts", // ✅ Correct - relative to project root "/src/config.ts", // ❌ Wrong - absolute paths not supported "./src/config.ts" // ✅ Correct - ./ is normalized and works ] }

Forward Slashes

Always use forward slashes (/) even on Windows:

{ "ignore": [ "src/config.ts", // ✅ Correct "src\\config.ts" // ❌ Wrong - backslashes not supported ] }

Glob Patterns

.stampignore supports glob patterns for matching multiple files:

{ "ignore": [ "**/*.secret.ts", // All .secret.ts files in any directory "**/secrets/**", // All files in any secrets/ directory "src/**/*.key.*", // All files with .key. in src/ and subdirectories "config/*.json" // All JSON files in config/ directory ] }

Supported glob patterns:

  • * - Matches any characters except /
  • ** - Matches any characters including / (recursive)
  • ? - Matches a single character
  • [abc] - Matches any character in the set
  • {a,b} - Matches any of the patterns

Creating .stampignore

Using stamp ignore Command (Recommended)

The easiest way to add files to .stampignore is using the stamp ignore command:

# Add a single file stamp ignore src/config/secrets.ts # Add multiple files/folders stamp ignore src/config/credentials.ts src/secrets/ # Add glob patterns stamp ignore "**/secrets.ts" "**/*.key"

The stamp ignore command:

  • Creates .stampignore if it doesn't exist
  • Adds paths to the file automatically
  • Prevents duplicate entries
  • Normalizes paths correctly

See ignore.md for complete documentation on the stamp ignore command.

Manual Creation

You can also create .stampignore manually in your project root:

# Create the file touch .stampignore # Add content cat > .stampignore << 'EOF' { "ignore": [ "src/config/secrets.ts" ] } EOF

Integration with Other Commands

  • stamp ignore <file> - Add files or folders to .stampignore (recommended way to manage exclusions)
  • stamp init - The init command runs a security scan by default, but .stampignore is completely optional and independent of security scanning

How It Works

Context Generation

When you run stamp context or stamp context style (equivalent to stamp context --include-style), LogicStamp:

  1. Reads .stampignore from the project root
  2. Filters out all files matching patterns in the ignore list
  3. Processes only the remaining files
  4. Shows how many files were excluded (unless using --quiet)

Note: Both stamp context and stamp context style respect .stampignore in exactly the same way. The style command is internally equivalent to stamp context --include-style, and file exclusion happens before any processing, including style extraction. .stampignore is completely optional - if it doesn't exist, all files will be processed normally.

Example output:

📦 Generated 5 bundles from 42 components ℹ️ Excluded 3 files via .stampignore

File Matching

Files are matched against .stampignore patterns using glob matching:

  • Exact paths match exactly
  • Glob patterns match according to their rules
  • Matching happens before file processing
  • Excluded files are never read or analyzed

Relationship with .gitignore

.stampignore and .gitignore serve different purposes:

  • .gitignore: Prevents files from being committed to version control
  • .stampignore: Prevents files from being included in LogicStamp context bundles

Note: .stampignore is independent of security scanning. The security report file (stamp_security_report.json) is automatically added to .gitignore by stamp security scan, but this is separate from .stampignore, which only affects context compilation.

Use cases:

  • Files in .gitignore are excluded from Git commits
  • Files in .stampignore are excluded from context compilation (but may still be committed)
  • Files can be in both (like secret files that shouldn't be committed OR included in context)

Best Practices

1. Commit to Version Control

Consider committing .stampignore to version control so your team knows which files are excluded:

git add .stampignore git commit -m "Add .stampignore for security"

This helps team members understand what's excluded and why.

2. Use Specific Paths

Prefer specific file paths over broad glob patterns when possible:

{ "ignore": [ "src/config/secrets.ts", // ✅ Specific "**/*.ts" // ❌ Too broad - excludes everything ] }

3. Keep It Updated

Regularly review and update .stampignore:

  • Remove files that are no longer needed
  • Add new files that should be excluded
  • Clean up patterns that are no longer needed

4. Don't Ignore Everything

Only exclude files that legitimately contain secrets or sensitive information. Don't use .stampignore as a general file exclusion mechanism—that's what .gitignore is for.

Troubleshooting

Files Still Being Included

If files are still being included after adding to .stampignore:

  1. Check path format:

    • Ensure paths are relative to project root
    • Use forward slashes (/) not backslashes (\)
    • Don't use absolute paths

  2. Verify JSON syntax:

    # Validate JSON cat .stampignore | jq .

  3. Check glob patterns:

    • Test patterns match the files you expect
    • Use ** for recursive matching
    • Escape special characters if needed

  4. Verify file location:

    • .stampignore must be in project root
    • Check the file is named exactly .stampignore (not .stampignore.json)

Reset .stampignore

To start fresh with .stampignore, simply delete the file:

# Delete .stampignore manually rm .stampignore

Or edit it to remove entries you no longer need.

Examples

Excluding Specific Files

{ "ignore": [ "src/config/api-keys.ts", "src/config/secrets.ts", "lib/credentials.js" ] }

Excluding Test Fixtures

{ "ignore": [ "tests/fixtures/secrets.ts", "**/__mocks__/secrets/**" ] }

Excluding Multiple Patterns

{ "ignore": [ "src/config/secrets.ts", "**/*.secret.ts", "**/secrets/**", "lib/**/keys.*" ] }
