http://d.puremagic.com/issues/show_bug.cgi?id=1772 Summary: regexp.split behaves incorrectly for paths with captures Product: D Version: 1.025 Platform: PC OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: Phobos AssignedTo: bugzilla digitalmars.com ReportedBy: wbaxter gmail.com I want to split columns out of a row of numbers. They may be separated by comas or by just white space. So I tried this: The splitter regexp auto re_splitter = new RegExp(r"(\s+|\s*,\s*)"); char[][] numbers = re_splitter.split(line); if input is a line like: 410.90711,352.879 The output from that is the array [410.90711,,,352.879] After a bit of debugging, it turns out the problem is the grouping in the regexp. Removing the parens fixes the problem in this case, but there are cases where you need parens for grouping and not for the capturing side effect. So I think this is a bug. Only match 0 should be considered significant for splitting, not the submatches. --

Further investigation shows that this: [410.90711,,,352.879] is actually this: ["410.90711", ",", "352.879"] and not a 4-element list with two empty strings as I thought. I discovered this because I checked what python does with captures, and it is this: """ If capturing parentheses are used in pattern, then the text of all groups in the pattern are also returned as part of the resulting list. """ So that made me think maybe D could be trying to do something similar. Apparently it is. So please just document it. --

Come to think of, I closed few D1 issues like this in the past, maybe we should close this one too (marked as D1 for now). D1/D2 regexp is broken in many ways and nobody is doing any work on Phobos/D1 to fix it AFIAK, Tango folks have their own regex anyway. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
