Can't Create URLs Shorter than Three Characters

[astorm]

If I attempt to create a new route for a module, and that module's front name is less than three characters

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
    <router id="standard">
        <route id="hello-world" frontName="hw">
            <module name="Pulsestorm_HelloPestle"/>
        </route>
    </router>
</config>

Magento's XML validator complains

Element 'route', attribute 'frontName': [facet 'pattern'] The value 'hw' is not accepted by the pattern '[A-Za-z0-9_\-]{3,}'.

It looks like the regular expressions for validating this element ([A-Za-z0-9_]{3,}) demands a frontName be at least three characters.

Based on the behavior of other PHP frameworks (which allow segments shorter than three characters), this is a bug and should be fixed.

It's not a URL's problem. The route id doesn't allow dashes but frontName does, you can set:
<route id="helloworld" frontName="hello-world">

@namluu You are correct! You can have dashes in the frontName. Useful, thanks! Updated the bug the reflect my annoyance on the limits of three character URLs instead :)

@astorm Thanks for pointing this out. I updated the routing topic with character restrictions.

BTW, in your example XML, you're using a path to the XSD instead of a URN.

Hi @astorm

Is it still an issue for you?

[antonkril]

Route Front Name has this limitation by mistake. It should be fixed.

Internal ticket MAGETWO-48333 was created to fix this issue.

Any update on this issues?

This is not yet fixed. Increased priority but I don't expect the fix in nearest release.

This was fixed in the scope of another ticket (MAGETWO-48495) and is in the latest develop branch. It will be included in the next release.
