Program Configuration Through Filename Reading: A Self-Contained Alternative to Flags and Scripts
By
Uptrenda
Lightly browned and well buttered. A solid pick from the rack.
Summary
The article discusses an alternative approach to program configuration where programs read their own filename instead of using traditional flags or scripts. This method allows the entire configuration to be embedded in the filename itself, making programs self-contained, portable, and easily shareable. The author argues that flags are ephemeral and scripts depend on environment variables that can break portability, while filename-based configuration solves both issues by making programs self-describing and requiring zero setup.
Key quotes
· 4 pulledPrograms usually get input from flags or scripts. But there's another way: a program can read its own filename.
That means the entire configuration can live in the file name itself, making programs self-contained, portable, and instantly shareable.
Flags are ephemeral – you have to share the command line or wrap it in a script. Scripts depend on environment, which can break portability.
Filenames solve both: the program describes itself, requires zero setup, and any configuration can be shared by simply renaming.
