Spelling Check Scripts

This directory contains a script to run cspell (Code Spell Checker) on the repository using the dependencies defined in the adjacent package*.json files.

Adding Legitimate Words

If the spell checker flags legitimate words as misspelled, you can add them to the dictionary configuration file located at .vscode/cspell.json.

Where to Add Words

There are two main places to add legitimate words. Maintain alphabetical order when adding words to keep the dictionary organized:

1. Root-level words array: Add words to the "words" array at the root level of the configuration file. This is the preferred location for project-specific terms, technical vocabulary, and commonly used words.

2. Baseline dictionary: Add words to the "baseline" dictionary under "dictionaryDefinitions". This is typically used for words that were already present in the codebase when the spell checker was first introduced.

Example

To add new words, edit .vscode/cspell.json and add them to the "words" array:

{
    "words": [
        "myprojectname",
        "customterm",
        "technicalword"
    ]
}

Guidelines

• Use lowercase for words
• Consider whether the word is truly legitimate or if it might be a typo

Available Scripts

PowerShell Version (Windows)

• File: Invoke-Cspell.ps1
• Usage: For Windows PowerShell environments

Usage Examples

# Check all files (default)
./eng/common/spelling/Invoke-Cspell.ps1

# Check specific files
./eng/common/spelling/Invoke-Cspell.ps1 -ScanGlobs 'sdk/*/*/PublicAPI/**/*.md'

# Check multiple globs (powershell invocation only)
./eng/common/spelling/Invoke-Cspell.ps1 -ScanGlobs @('sdk/storage/**', 'sdk/keyvault/**')

# Check single file
./eng/common/spelling/Invoke-Cspell.ps1 -ScanGlobs './README.md'

Parameters

• Job Type: The cspell command to run (default: lint)
• Scan Globs: File patterns to check for spelling
• Config Path: Location of the cspell.json configuration file
• Spell Check Root: Root directory for relative paths
• Package Cache: Working directory for npm dependencies
• Leave Cache: Option to preserve the npm package cache

Requirements

• Node.js and npm must be installed
• The .vscode/cspell.json configuration file must exist
• jq command-line JSON processor (for bash version)

How It Works

1. Creates a temporary working directory for npm packages
2. Copies package.json and package-lock.json to the working directory
3. Installs npm dependencies using npm ci
4. Modifies the cspell configuration to include specified file globs
5. Runs cspell with the modified configuration
6. Restores the original configuration
7. Cleans up temporary files

The scripts ensure that a LICENSE file (or temporary file) is always included in the scan to meet cspell's requirements for the "files" array.
