Rename-gate: file names vs sanity
Forget Flags and Scripts: Just Rename the File
Dev says “just rename the app”; internet screams genius and madness
TLDR: A developer pitched apps that read their own file name for all settings, promising plug‑and‑play sharing by renaming files. Commenters split hard: jokers mocked “classname soup” and renaming AI chats, while a few praised zero‑setup convenience—boiling down to a clash between convenience and clarity that could reshape how we share tools.
A bold proposal just dropped: skip command-line switches and setup scripts, and instead make the app read its own file name for settings. Think installers you can repurpose by renaming, AI experiments that run from a single file like train---resnet50---lr0.001.exe, or even one-click friend VPNs for game night. Rename the file, change the behavior. Zero setup, maximum portability—at least on paper.
The comments? Absolute fireworks. Quarrelsome opened with “this is satire, right?” and the tone was set. Critics argued it confuses identity with configuration, makes version control chaotic, and turns finding options into a scavenger hunt. castral warned every reading would become “an expensive find and grep lesson,” while csb6 fired the crowd-pleaser: “foo--bar.exe doesn’t seem any easier than foo.exe --bar.”
Then came the memes. One joker imagined skipping the tech entirely: “Just rename Claude.exe and it starts a new chat.” Another called it the Tailwind CSS moment for command lines—“classname soup,” but in your Start menu. A few thrill-seekers loved the zero-setup fantasy, picturing files you can pass to friends that “just work.” But the louder chorus feared unsearchable names, awkward upgrades, and support nightmares. Brilliant hack or chaos engine? The thread can’t decide, but it’s having a blast trying.
Key Points
- •The article proposes configuring programs by parsing their own filenames instead of using flags or scripts.
- •It argues this method improves portability and shareability by making executables self-contained and reproducible.
- •A reusable installer example shows encoding a Python module name in the filename to automate setup and dependencies.
- •An ML experiment runner example encodes model, hyperparameters, and dataset in the filename to auto-run and reproduce experiments.
- •Additional examples include ad-hoc utilities and a P2P VPN tunnel setup using ECDSA keys for simple endpoint configuration.
