[Pythonmac-SIG] HFS versus POSIX paths (changed from fixing the documentation)

[Daniel Lord]

I changed the topic so many can avoid it and we don't bore them to tears ;-) On Apr 20, 2006, at 2:02, has wrote: As for working with HFS paths (and a pox on scriptable apps that require them, btw, because they're fundamentally unreliable), you ought to be able to use Carbon.CF to translate between POSIX/Windows/HFS path styles. Unfortunately, I suspect getting in and out of there may be one of the areas that's broken. I am writing an app combining excel and python/appscript to fetch quotes from the web and value stock portfolios .  But I give up on using appscript with Excel--some things just don't work because I think the terminology is seriously warped if no broken. Applescriptworks but appscript doesn't. I instead build a text Applescript from strings and use popen2 to invoke osascript like this example which reads in the stock symbols from a named range in an excel spreadsheet:     def readSymbolList(self, workbook, worksheet, range):         _getSymbolsScript = """tell app "Microsoft Excel"              return Value of Range "%s" of Worksheet "%s" of Workbook "%s"             end tell"""         # read symbols from spreadsheet          cout, cin = popen2.popen2( "/usr/bin/osascript -e \'%s\'" % \             (_getSymbolsScript % (range, worksheet, workbook)))         symbols = cout.readline()[:-1]         symbols = re.sub(",\s",",",symbols)         if (self.DEBUG):             print __module__, "::","symbols=", repr(symbols)         # create symbolList         symbolList = []         symbols = string.split(symbols, ",")         if (self.DEBUG):             print __module__, "::","stocks=", repr(symbols)         for symbol in symbols:             if (symbol != '0'):                 symbolList.append(symbol)         cout.close()         cin.close()         return symbolList I wouldn't mind adding a makewithhfspath class method and hfspath instance method to macfile's Alias and File classes, but I'd want to be sure I had a correct implementation first, however, as it's not quite as trivial as it sounds on the surface (e.g. volume names are not a direct translation in either direction). If you really desire to you can but I just wrote a quick hack using re.sub() that correctly converts the paths I use so my needs are met. Daniel
