OSH directory standard - Rust library

License: AGPL-3.0-or-later REUSE status Repo Package Releases Documentation Releases Dependency Status Build Status

In cooperation with FabCity Hamburg In cooperation with Open Source Ecology Germany

  • OSH: Open Source Hardware

Code that helps humans and machines deal with the OSH directory standard.

This consists of two parts:

  1. osh_dir_std - a (Rust) library to parse the specification(s) into easily usable structures & accompanying utilities
  2. osh-dir-std - a CLI tool that helps checking a given projects file listing against one or multiple specifications.

NOTE
This only checks the paths of files and directories against a set of presets (aka "standards"). It does not check the content of any files in any way.

Example Usage

CLI

Installation

From Source
Fetch & Compile
cargo install osh-dir-std
Local Sources
cargo install --path bin

Usage

The tool expects a new-line separated listing of files (and optionally directories) of the project, either on stdin, or in a file given as the first argument. This list might come from git (or any other version control system (VCS) used), the file-system directly, a ZIP file or even a web-site that lists the files.

A few examples of how to list files in different scenarios, to rate the project against the known directory standards:

git:

git ls-files --recurse-submodules | sed -e 's/^"\(.*\)"$/\1/' | osh-dir-std rate

SVN:

svn ls | osh-dir-std rate

Mercurial (hg):

hg status --all | osh-dir-std rate

pijul:

pijul list | osh-dir-std rate

file-system:

ls -r1 | osh-dir-std rate

sample output:

[
  {
    "name": "unixish",
    "factor": 0.62724684
  },
]

A factor of 1.0 would mean that the projects file- and directory structure adheres 100% to the respective standard. unixish is the name of the default directory standard.

Library

Setup

Cargo.toml:

[dependencies]
osh_dir_std = "0.7.2"

Code

use osh_dir_std::{self, format::Rec};

fn find_rec(std: &str, record_path: &str) -> Result<&'static Rec<'static>, String> {
    for rec in &osh_dir_std::data::STDS.get(std).unwrap().records {
        if rec.path == record_path {
            return Ok(rec);
        }
    }
    Err(format!(
        "Failed to find record with path '{record_path}' in the '{std}' dir standard"
    ))
}

/// Checks whether the dir std "unixish" contains the record "res/",
/// and whether that record is a _fixed_ one. See [the definition](
/// https://github.com/hoijui/osh-dir-std/blob/main/definition_format.csv)
/// for an explanation of what _fixed_ means.
#[test]
fn unixish_res_fixed() -> Result<(), Error> {
    let rec = find_rec("unixish", "res/")?;
    assert!(rec.fixed);
    Ok(())
}

    (also uses this tool internally)
