Difference between install package via composer-asset-plugin and bower

[macklay]

Im try to compare marionette js install via composer and bower.
Marionette has bower.json with such JQuery dependency:
"jquery": "^1.8.0 || ^2.0.0"

And bower install jquery 2.1.1 - its the latest vesion of jquery
But composer-asset-plugin install too old version: 2.0.3

If Im set last jquery version manualy in deps in composer json, composer insatll veeeery old marionettejs(wich has not any jquery dependence)

(in this test case, composer and bower json file contain only one package: "marionette")

bower output:

Can you copy me the file composer.json please?

[macklay]

@francoispluchino,

composer.json 
{
    "name": "test",

    "minimum-stability": "dev",
    "require": {

        "bower-asset/marionette": "*"
    },

    "extra": {
        "asset-installer-paths": {
            "npm-asset-library": "vendor/npm",
            "bower-asset-library": "vendor/bower"
        }
    }
}

[francoispluchino]

The behavior of the update is very strange!

[macklay]

@francoispluchino,
the behavior of the install, output the same result and therefore its very strange too ;)

Maybe bower version ^2.0.0 readed by composer as ~2.0.0 ?

[francoispluchino]

I found the problem. The plugin converts the range version ^2.0.0 to ~2.0.0. They have, according the doc, the same behavior: replace by >=2.0,<3.0.

However, Composer has a special, ~2.0.0 is not converted to >=2.0.0,<3.0, but to >=2.0.0,<2.1 (see the doc).

[francoispluchino]

The problem is in the class Fxp\Composer\AssetPlugin\Converter\SemverConverter line 130
