Has someone ever built a "sort block generator"
Hi guys, Currently I have some sorting blocks which support "nil" elements (making them go first). So here is a general nil tolerant sort block based on one field: defaultNilTolerantSortBlock: aBlock [ :a :b | a ifNil: [ true ] ifNotNil: [ b ifNil: [ false ] ifNotNil: [ aBlock value: a value: b ] ] ] Now...imagine that now I want to first on element1, then over element2...and both could be nil...in which case should go "first". Anyway...does someone ever built some tool where you pass an ordered set of closures and it builds the super ugly resulting sort block? Cheers, -- Mariano http://marianopeck.wordpress.com
Hi mariano what are you doing? because it looks strange to need a sort block generator :). Why cann't filter all the objects that have either fields to nil first? Stef On 31/7/14 19:40, Mariano Martinez Peck wrote:

I think Mariano would like something like this: persons sorted: #(lastname firstname birthdate) asSortBlock that would sort by lastname, and if lastnames are equal by firstnames and if both lastnames and firstnames are equal by birthdate. -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Y asked for the same thing a few days ago in http://forum.world.st/Multiple-sorting-helper-td4770613.html Something like: sorter := MultipleSortCriteria new add: #lastName; add: [:each | each personalInfo age ] ascending: false. aCollection asSortedCollection: sorter. you could add something like: sorter := MultipleSortCriteria new add: #lastName; add: #firstName ascending: false nullsFirst: true. aCollection asSortedCollection: sorter.

Exactly!!! And... what is most important for me, is that to the MultipleSortCriteria I would like to ask #sortBlock :) Thanks Esteban for better explaining what I was looking for ;)

Grids, collections, and sorting/filtering + paging. And xls export. I guess we all have this kind of need in Seaside apps (and/or datatables). Maybe we could have a hangout about these things. I use the MagritteReport thing with some Twitter Bootstrap additions for reports. Is there any best practice article somewhere that you use as a reference for your designs?

+1 Note that I have a public experimental port to Pharo in SmalltalkHub that I already announced once (in http://smalltalkhub.com/#!/~nice/NiceVMExperiments <http://smalltalkhub.com/#%21/%7Enice/NiceVMExperiments/versions/VMMaker.osco...> but I can't tell exactly the package name TagSortFunction or something like that, the web interface of SmalltalkHub is currently showing me a debugger with nil does not understand #data). Yes, I know VM-experiments is not the right place for such package, but at the time I didn't find where to create a new project... Since I got absolutely zero feedback after a long thread, I assumed it was not interesting anybody... But my personal opinion differs: this should be included in each and every Smalltalk.

I decided to embrace you initial port and also made some enhancements to TAGSortFunctions. I added the current features: * Support of MAElementDescription conversion to SortFunction (in addition to block and unary symbol support) * Collation of nil elements, deciding whether to put nil at the end or beginning of the result. (similar to the ORDER BY column [NULLS FIRST|LAST] semantics of SQL). Unit tests for the above described features. All the added features preserve the original behavior of the sort functions, so nil collation must be "enabled" explicitly by sending #undefinedFirst/#undefinedLast to the sort function, otherwise it will fail if you attempt to compare an object with nil. I would like to move this to a specific repository in STHub with its own Metacello config (Magritte support is packaged separately). Do you agree with this? Regards! Esteban A. Maringolo

To sort a collection with such an object it only has to answer #value:value:, so is there a special reason you want to generate a block from it? Because generating such blocks might be a bit cumbersome and the object already does the job, no?

you could add something like: sorter := MultipleSortCriteria new add: #lastName; add: #firstName ascending: false nullsFirst: true. aCollection asSortedCollection: sorter.
