pathasposixasposix

Pathasposixasposix is a fictional theoretical framework for representing filesystem paths using a POSIX-oriented syntax across different operating systems. The name combines path semantics with POSIX conventions to describe a canonical form that is intended to be portable between POSIX-compliant environments and non-POSIX platforms. It is discussed as a design concept in cross-platform tooling and library design rather than as a formal standard.

Origin and motivation: Pathasposixasposix emerged from discussions among developers seeking uniform path handling across languages and runtimes that expose different path APIs. Proponents argue that a POSIX-like representation can simplify validation, storage, and transmission of paths in configuration files, logs, and network protocols while preserving core semantics.

Technical description: The concept specifies that path strings adopt forward-slash separators and define normalization rules for redundant separators, current and parent directory references, and special characters. A path object in this model provides operations for joining, resolving, and computing relative paths, with semantics aligned to POSIX rules where feasible. Optional mappings are defined for platform-specific features such as drive letters or mount points to maintain readability while preserving a POSIX-like structure.

Usage and interoperability: Pathasposixasposix is presented as a tool for cross-language libraries, config parsers, and data interchange formats that require stable path serialization. It aims to decouple path syntax from underlying OS file APIs, enabling consistent validation, storage, and display across platforms.

Limitations and critique: Critics note that some OS features—such as symbolic links with differing semantics, case sensitivity, permissions, and device files—do not map cleanly to a purely POSIX representation. Implementations often need extensions or dual representations to preserve full semantics and security guarantees.
