[augeas-devel] exports lens and host-names

[Sergio Ballestrero]

Hello, 
it looks like in the current augeas (v7.4) the "exports" lens fails to deal with hostnames containing dashes. If I look at the regular expression used, it seems correct (in /usr/share/augeas/lenses/dist/exports.aug):
 let client_re = /[a-zA-Z0-9\-\.@\*\?\/]+/

so as an newbie in augeas lenses I'm not understanding where the problem may come from. Can someone point me at where to look?

I've extended the test_exports.aug in case it helps - see below. 

Cheers, and thanks,
 Sergio
PS besides few little hiccups, Augeas is a blessing! :-)
