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."
