Compare two semver version strings with variable length and cutomizable separators, returning -1, 0, or 1
npm install semver-compare-multiCompare two semver version strings, returning -1, 0, or 1
They don't need to be strict x.y.z formated strings, the size is automaticaly checked. As the size is dynamic, comparing cmp("1.0.0", "1.0.0.1")returns -1, that is, the longer version is considered greater.
The return value of cmp can be fed straight into [].sort.
You can pass newComparer, which returns an cmp(a,b), an array of characters to match as split points, mind to escape regex special symbols with \\, as of: newComparer(["\\.", "-"])
`` js`
import { cmp } from "semver-compare-multi";
var versions = [
'1.2.3',
'4.11.6',
'4.2.0',
'1.5.19',
'1.5.5',
'4.1.3',
'2.3.1',
'10.5.5',
'11.3.0'
];
console.log(versions.sort(cmp).join('\n'));
Or
` js`
import { newComparer } from "semver-compare-multi";
var versions = [
'1.2-3',
'4.11_6',
'4.2_0',
'1.5-19',
'1.5-5',
'4.1-3',
'2.3_1',
'10.5_5',
'11.3_0'
];
console.log(versions.sort(newComparer(["\\.", "-", "_"])).join('\n'));
prints:
`
1.2-3
1.5-5
1.5-19
2.3_1
4.1-3
4.2_0
4.11_6
10.5_5
11.3_0
whereas the default lexicographic sort (versions.sort()) would be:
`
1.2-3
1.5-19
1.5-5
10.5_5
11.3_0
2.3_1
4.1-3
4.11_6
4.2_0
`
import { cmp, newComparer } from "semver-compare-multi";
If the semver string a is greater than b, return 1.b
If the semver string is greater than a, return -1.a
If equals b, return 0;
It is the same as newComparer(), which returns an cmp(a, b) with "." and "-" default separators.
With npm do:
`
npm install semver-compare-multi
