107-120: Excellent example forScanTokens!This example clearly demonstrates how to use the new
ScanTokensfunction withbufio.Scannerto process null-terminated strings. The function correctly shows how tokens are separated by null characters and provides appropriate output expectations.cmd/escargs/escargs.go (1)
65-65: Good replacement with standardized function.The custom
splitNullTerminatedItemsfunction has been properly replaced with the new standardizedshellescape.ScanTokensfunction, providing better code reuse and consistency.shellescape.go (1)
71-88: Well-implemented split function for bufio.Scanner.The implementation correctly handles all required cases for a split function:
- EOF with no data
- Finding tokens separated by null bytes
- Final non-terminated line at EOF
- Requesting more data when needed
This follows the standard pattern for
bufio.Scannersplit functions and handles edge cases appropriately.shellescape_test.go (1)
88-105: Comprehensive test for the new ScanTokens function.The test properly validates that:
- Multiple tokens separated by null bytes are correctly extracted
- The scanner processes all tokens in the expected order
- No scanner errors occur during processing
This provides good coverage for the new functionality.
