Streams
Streams
The Streams module provides stream processing and compression functionality for the SCM programming language. This module includes:
- Stream creation: Functions to create streams from string content (streamString)
- Compression: Stream compression using gzip and xz algorithms
- Decompression: Stream decompression using zcat (gzip) and xzcat (xz) functions
These functions enable efficient handling of data streams, file compression, and decompression operations in SCM programs, particularly useful for processing large datasets and file I/O operations.
