# 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:
```json
{
"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
```powershell
# 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.
