Webi's Host & Asset Target Triplet Classifier

Determine Host Target Triplet (Arch, Libc, OS, Vendor) from a filenames / download URL and uname / User-Agent strings.

Also compares versions lexicographically.

require('./build_classifier/host-targets.js')

HostTargets.termsToTarget(target, terms)
// Example:
// { arch: 'x86_64', os: 'linux', libc: 'musl' }

Don't rely on these as part of the API, but they're available to inspect.

(they're used for matching uname and User-Agent values to target triplets)

HostTargets.WATERFALL // { darwin: { aarch64: ['aarch64', 'x86_64'] } }
HostTargets.TERMS     // { amd64: { arch: 'x86_64' } }

require('./build_classifier/lexver.js')

Turns versions in just about any format into a Lexicographically Sorted version.

Lexver.matchSorted(versions, prefix)  // v1 => v0001 matches v0001.0000.0000@
Lexver.toTags(lexvers)                // sorts and calls sortedToTags
Lexver.sortedToTags(descLexvers)      // gets { latest, stable, default }
Lexver.parseVersion(fullVersion)      // 'v1-beta1' => 'v0001.0000.0000-beta-0001'
Lexver.parsePrefix(version)           // v1 => v0001

require('./build_classifier/triplet.js')

Turns a filename or URL, along with project and release info, into a target triplet.

Triplet.maybeInstallable(proj, build);    // exclude non-build assets
Triplet.toPattern(proj, build);           // foo-1.0.0-mac64 => {NAME}-{VER}-mac64
Triplet.patternToTerms(filename);         // {NAME}-mac-x86.64 => [ 'mac', 'x86_64' ]
Triplet.termsToTarget(
    target, proj, build, terms            // => 'x86_64_v2-pc-windows-msvc'
);
Triplet.buildToPackageType(build);        // uses 'build.name' or 'build.download'
Triplet.filenameToPackageType(filename);  // ex: '.zip', '.app.zip', '.tar.gz', ''

Don't rely on these as part of the API, but they're available to inspect.

(they're used for excluding and classifying release assets)

Triplet.TERMS_CHECKSUM             // [ 'MD5SUMS', 'SHA1SUMS', '...' ]
