## README

# STDF parser
Standard Test Data Format V4 parser

# Cli
```bash
npm install -g stdf-parser
stdf-parser a.stdf
less a.stdf.ndjson
```

## Usage

### Stream Parser (Recommended for large file)
```typescript
import {StdfParser} from 'stdf-parser'
import {once} from 'events'

const stream = createReadStream(filename)
const parser = stream.pipe(StdfParser.stream())
for await (const record of parser) {
  if (record instanceof PtrRecord) {
    console.log(record)
  }
}
```

### Buffer Parser (Faster for small file)
```typescript
import {StdfParser} from 'stdf-parser'
const file = readFileSync(filename)

console.time('parse')
const stdfFile = StdfParser.parse(SmartBuffer.fromBuffer(file))
console.log(stdfFile.records.length)
```

_warning: may use 2-3 times memory of file size_
