IOREPARSETAGSYMLINK

IOREPARSETAGSYMLINK is a software utility within the IORE ecosystem that reads a YAML configuration describing a set of tags and their associated targets, and creates symbolic links accordingly. It is used to expose resources through a stable tag-based namespace, enabling consistent references across environments and deployments.

Operation: The utility consumes a YAML file that defines mappings from tag names to target paths or URLs. It also accepts a destination directory where the generated symlinks will reside. For each tag, IOREPARSETAGSYMLINK creates a symbolic link named after the tag that points to the specified target. The tool supports absolute and relative targets, path validation, and optional resolution of environment variables. A dry-run option reports planned changes without modifying the filesystem.

Options and behavior: It can filter which tags to process, overwrite existing links, and preserve existing links if they point to the same target. It performs basic cycle detection to avoid linking loops, and it logs operations to an optional log file or stdout. It handles permissions errors gracefully and provides an exit status indicating success or failure.

Usage pattern: Prepare a YAML file with tag-to-target mappings, choose a destination directory, and run the utility. In workflows, it can be integrated into build pipelines or deployment scripts to maintain a centralized, tag-based reference layer.

Limitations: The YAML structure is simple: a top-level mapping from string tags to target paths. Complex nesting requires preprocessing.
