From: W. Trevor King Date: Thu, 15 Mar 2012 17:31:14 +0000 (-0400) Subject: Add ListSetting and IntegerListSetting types. X-Git-Tag: v0.2~14 X-Git-Url: http://git.tremily.us/?p=h5config.git;a=commitdiff_plain;h=fd0e1151f481bb28e205db3c03dc40f57947bf42 Add ListSetting and IntegerListSetting types. Also add the storage instance to test assertion error. Peering through the logs looking for 'testing {}' wasn't cutting it ;). --- diff --git a/h5config/config.py b/h5config/config.py index 4aa9e91..478ac3f 100644 --- a/h5config/config.py +++ b/h5config/config.py @@ -178,28 +178,28 @@ class FloatSetting (NumericSetting): return float(value) -class FloatListSetting (Setting): -
