AW: [Newbies] Walk directory of files?

Hi Charles,
No Squeak handy but there is a allfilesinalldirectories. This will give you all files in all subfolders. Tonight I will look up the real name but you may be able to find it in FileStream or similar yourself. Cheers Herbert -------- Ursprüngliche Nachricht -------- Von: Charles Hixson <[hidden email]> Datum: 21.10.2013 9:14 (GMT+01:00) An: [hidden email] Betreff: [Newbies] Walk directory of files? What is the best way to walk a directory of files? It would be nice is I could just: Get next file? exitst? ifFalse then done match pattern? ifFalse, then go to first step return file This requires that the method track where I am. I think I can figure out how to stuff them into a collection, and return the entire collection of matched files, and perhaps that's the right answer, but that's not the way I would do it in Python or Ruby, so perhaps it's also not the way to do it in Smalltalk. Also, if it matters, the files will be utf-8 files, many of them with BOMs. (Well, not really BOMs, since it's utf8, but the utf8 header.) Does Squeak recognize BOM headers? -- Charles Hixson _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners |

Hi Charles,I think that means I should use Files-Directories : FileDirectory : fullNamesOfAllFilesInSubtree and store the collection as I walk through the files processing them rather than use what Python would call a generator. Do you know whether when reading a utf8 file the BOM is recognized? Or do I need write a handler to strip it off? -- Charles Hixson _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners |

This may be closer to what you are looking for: FileDirectory default withAllFilesDo: [:file | "Do something with the FileStream here"] andDirectoriesDo: [:dir | "Do something with the FileDirectory here"].

In reply to this post by Charles Hixson-2
Charles,
you're right (I assumed you'd find it once you know it's there :-)) Never had to care about BOM headers, so I didn't know what they are until I looked them up now. But I read UTF8 files all the time. Entering bom in the search field yields some methods e.g. in UTF8TextConverter, I assume that's why I never ran into it. Seems to 'just work' (TM). Also there's FileDirectory>>fileNamesMatching: which may help you with your file names matching. Re generators, make a seperate post for a new topic, people may assume I replied already. Or try Squeak dev. Cheers, Herbert Am 21.10.2013 19:14, schrieb Charles

Charles,If you don't know about generators, and know about file handling, I'll assume that that's not the Squeak idiom. I can do the same thing with a Collection, I just do things in a slightly different order. And thanks for the help. -- Charles Hixson _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners |
