obiutils Package: Semantic Overview
The xopen.go test suite (via GoCheck) validates utility functions for flexible file/stream I/O in Go. Key features:
IsGzip(): Detects gzip compression by inspecting the first two bytes (0x1f 0x8b) of abufio.Reader.Ropen(): Unified reader opener supporting:- Local files (plain or
.gz) - Standard input (
"-") — note: currently unimplemented in tests - HTTP(S) URLs (via
net/http)
- Local files (plain or
Wopen(): Unified writer opener for:- Local files (
".gz"triggers gzip compression) - Standard output via
"-"
- Local files (
Exists(): Checks file/directory existence (supports~expansion).ExpandUser(): Expands shell-like paths (~/...) to absolute ones.- Tested robustness:
- Handles missing files, invalid URLs (404), and malformed paths.
- Validates gzip detection accuracy on both plain and compressed data.
All operations abstract away compression/format details, enabling uniform read/write semantics across local files, pipes (commented out), and remote HTTP resources.
