I've run all tests of CommandShellTestCase in the Test runner multiple times: 1. run: all green 2. run: error in testPipeline75 (re-running this test succeeded, so I don't know what the error was) 3. run: test runner hangs in testIfThenElse02 because indefinitely waiting on completionSemaphore in #evaluatePipelines: restarted the VM 1. run: all green 2. run: same as 3 above 3. run: same as 3 above 4. run: error in testPipeline72 5. run: all green I haven't seen any defunct processes, though.

And Juan's editor displaying 'lf' glyphs is like 'wellcome back, to hell'. Squeak's text editor allows you to do some formatting, like changing font, emphasis, color and more special things like links etc.. And once you changing text using this, you can't represent it as plaing text without losing formatting information, and from that point preserving line ends becoming too minor issue comparing to fact that you can't preserve formatting. As to me, from this side, a text editor behaves like html renderer, while displaying control characters is analoguous to displaying html source instead of rendering it. Now tell me, have you seen html renderer , which instead of rendering page - showing you tags? Or if you prefer to see html source, then it is logical to diplay all other kinds of formatting with plain text (by using some kind of markup), instead of reflecting them visually. No? And then, don't you think that rendering html and displaying html is done using different tools, because obviously it is two different representations of same document. And nobody mixing them (you don't see any tags when browsing, while can see them when looking at source), while Juan's modification looks like a mixture of two different modes - 'raw' mode, when you can see source and rendering mode - when you see the designed document. Such kind of mixture is awfully wrong. So, if you want to see line feeds in text, then get rid of text formatting features first, or make two SEPARATE TOOLS, each specialized on different displaying mode. >> Instead, import should deal with >> normalizing the input to a form, edigible by editor, and then export >> layer (file-out or whatever) may be instructed to save edited file >> using one or other line-ends, but editor should use own convention(s) >> and free to choose own ways how internally store the edited text. >> >>> My point of view on this is : >>> Â Â Â Â - when I manipulate the text object may be we should have the platform convention. >>> Â Â Â Â - when I edit a file I should get the control because I may want to edit a file on mac with unix convention. >>> >>> So nicolas I saw that you pushed a slice about fixing end of line. >>> What is the design behind it? >>> >> >> Stef, you can always read a full discussion about it on squeak-dev archives. >> http://n4.nabble.com/support-of-various-line-ends-in-trunk-td622338.html#a6… > > No time for that now. > >> >>> Stef >>> _______________________________________________ >>> Pharo-project mailing list >>> Pharo-project(a)lists.gforge.inria.fr >>> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >>> >> >> >> >> -- >> Best regards, >> Igor Stasenko AKA sig. >> <text.txt><cuis-editor.png><hexdump.png>_______________________________________________ >> Pharo-project mailing list >> Pharo-project(a)lists.gforge.inria.fr >> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > -- Best regards, Igor Stasenko AKA sig.

Re: [Pharo-project] OSProcess - working on gnuplot

by David T. Lewis

Adrian, Thanks *very* much for the detailed feedback. I do want to ask a couple more questions if your patience holds up. First question: I am getting serious failures on CommandShellTestCase that still worry me. For example, if I evaluate this (on Linux VM with Pharo image): (CommandShellTestCase selector: #testEvaluateOrMakePipelinesFrom) debug I find that the test never completes. It is stuck waiting for the various external processes to be cleaned up, and the console output shows the zombie processes whose exit signals have not yet been handled by the image: lewis@linux-6xfc:~/squeak/Pharo/pharo1.0-10495-rc1dev09.11.3> ps PID TTY TIME CMD 3877 pts/51 00:00:00 bash 9695 pts/51 00:00:00 xterm 10060 pts/51 00:00:45 squeakvm 10268 pts/51 00:00:00 ls <defunct> 10269 pts/51 00:00:00 cat <defunct> 10271 pts/51 00:00:00 cat <defunct> 10272 pts/51 00:00:00 wc <defunct> 10273 pts/51 00:00:00 ps <defunct> 10274 pts/51 00:00:00 cat <defunct> 10275 pts/51 00:00:00 cat <defunct> 10279 pts/51 00:00:00 ps lewis@linux-6xfc:~/squeak/Pharo/pharo1.0-10495-rc1dev09.11.3> Do you see problems like this when you run CommandShellTestCase? Second question: Some of the failures you are getting look like things that I thought that I had fixed in the past (but I'm not sure). The latest versions from the SqueakSource repositories should be: OSProcess-dtl.53 Tests-OSProcess-dtl.20 CommandShell-dtl.40 Tests-CommandShell-dtl.14 Could you please double check your versions of OSProcess, CommandShell and the unit tests to see if they match these MC versions? Thanks a lot, I really appreciate the help.

IMO, a useful behavior for a text file editor is to: * On open, detect the line end convention of the file and remember it. This is not too hard to do as long as the file is in fact a text file (if it's a binary file you shouldn't be using a text editor on it). * On save, save in the same line end convention that the file previously had. * On "save as" provide the opportunity to change the line end convention as well as the file name. * New files should default to the platform's line end convention, but again be overridable on save.
