[Pharo-project] rubric performace

by Tudor Girba

Hi, I did a little experiment to check the performance of Rubric when dealing with large content. And by large, I mean 45 MB or about 15 million lines of text. I opened the file in several other editors: - TextMate: 10s + the text is wrapped and can be browsed smoothly - Sublime Text 2: 10s + the text is wrapped and can be browsed smoothly - Eclipse: 5s + browsing is very slow (so it is basically useless) How did Rubric perform: - When opened with unwrapped lines: 33s + the text can be browsed smoothly - When opened with wrapped lines -> Pharo crashed :( In any case, I think being 3 times slower (even if without wrapping) than TextMate is highly exciting. Great job Alain. If you want to reproduce the experiment, here is the Smalltalk snippet I used: --- Gofer new smalltalkhubUser: 'AlainPlantec' project: 'Rubric'; package: 'Rubric-AlainPlantec.26'; load. [ contents := ((FileSystem disk workingDirectory / 'src' / 'ArgoUML-0-34' / 'output.mse') readStreamDo: #contents). (RubLipsumBasicExample windowWithScrolledText: ( RubLipsumBasicExample new string: contents; newScrolledTextNotWrapped)) openInWorld ] timeToRun --- Cheers, Doru -- www.tudorgirba.com "What we can governs what we wish."

[Pharo-project] [ANN] elasticsearch client

by Paul DeBruicker

Hi - Elasticsearch (http://www.elasticsearch.org/) claims to be a: "flexible and powerful open source, distributed real-time search and analytics engine for the cloud" I put what I've made up here: MCHttpRepository location: 'http://ss3.gemstone.com/ss/Elasticsearch' user: '' password: '' So far it allows you to create an index, add documents, get documents by id, search using the URI Request api, and then delete the index. I made it in Pharo 1.4. I made an attempt to abstract out the HTTP client and URL stuff so it could be used with Zinc or Webclient. But right now it only works with Zinc. If someone wants it to run in Squeak sooner rather than later let me know and I can either fix it and the config or help you do it. basic usage is like this: index:= ESIndex createIndex: 'test-index'. docContent := Dictionary new. docContent at: 'message' put: 'this is the documents content'. docContent at: 'creator' put: 'Mr T'. document:=ESDocument withContent: docContent. document addToIndex:index. search:=ESURISearch index:index. search queryString:'documents'; search. search results explore. ESIndex deleteIndex:'test-index' I haven't begun implementing the QueryDSL but the ESSearch class does do the required GET with a JSON body and does work. Seems like it'd be useful to have the QueryDSL but right now I don't need more than the URI Request searching provides. It also doesn't do any of the cluster health/maintenance api yet
