Look like #ifNotEmpty: is the correct choice. Collection methods select: [ :m | (m selector includesSubstring: 'if' caseSensitive: false) and: [ m selector includesSubstring: 'empty' caseSensitive: false ] ] thenCollect: [ :m | m -> m senders size ]
"{ Collection>>#ifEmpty:->188. Collection>>#ifNotEmpty:->113. Collection>>#ifNotEmptyDo:ifEmpty:->0. Collection>>#ifEmpty:ifNotEmpty:->80. Collection>>#ifEmpty:ifNotEmptyDo:->0. Collection>>#ifNotEmptyDo:->0. Collection>>#ifNotEmpty:ifEmpty:->14 }" Best regards, Henrik From: Pharo-users [mailto:pharo-users-boun...@lists.pharo.org] On Behalf Of Peter Uhnák Sent: Saturday, October 10, 2015 6:55 PM To: Pharo Users List <pharo-users@lists.pharo.org> Subject: [Pharo-users] ifNotEmpty(Do): Collection>>ifNotEmpty: comment says "If the block has an argument, eval with the receiver as its argument, but it might be better to use ifNotEmptyDo: to make the code easier to understand" yet when I do that, Code Critic complains: ifNotEmptyDo: should not be used as ifNotEmpty: works for blocks with arguments, too. 1) who is right? what should I use? 2) shouldn't one be deprecated then? (or maybe one of them is to be compatible with other smalltalks?) Thanks, Peter
