namespaces - Any notes or rules for naming ruby gems with '-' or '_'? -

-

this question has answer here:

when create ruby gem , name it, paying attentions name '-' or '_' ? there differences use between '-' , '_'?

$ gem list|egrep "\-|_" actionmailer-with-request (0.4.0, 0.3.0) activerecord-deprecated_finders (1.0.2, 0.0.3) activerecord-import (0.3.1) : :

i feel there rules not sure @ moment. take learn rules or guidances if exist. , want take @ code of gems (near-)perfectly compliant roles if know gems named '-' or '_', please give answers well.

there examples of gems don't follow convention. convention have come best using - denote namespace (::) boundary , _ word separator within class name.

examples:

| main class        | gem name          | require           | |-------------------|-------------------|-------------------| | redis             | redis             | redis             | | redis::namespace  | redis-namespace   | redis/namespace   | | redis::nativehash | redis-native_hash | redis/native_hash |
