  • parsing string according to oracle operators with regex

    - by haluk
    Hi, Basically I was trying to replace the part of string with its actual value which comes immediately after oracle operators. I can do this for limited operators list like {=,,<} but I wonder that is there any way out to gather all the operators rather than giving them by hands? For instance, I have this string; "a = xyz", then I will replace xyz with lets say 3. But as you know we have bunch of operator namely "like,in,exists etc". So my string can also be this: "a like xyz". So what do you suggest me? Thanks.

  • Recursive CTE Problem

    - by Chris
    Hi, I am trying to use a recursive CTE in SQL Server to build up a predicate formula from a table containing the underlying tree structure. For example, my table looks like: -------------------------- Id Operator/Val ParentId -------------------------- 1. 'OR' NULL 2. 'AND' 1 3. 'AND' 1 4. '' 2 5. 'a' 4 6. 'alpha' 4 : : : -------------------------- which represents ((a alpha) AND (b beta)) OR ((c gamma) AND (a < delta)). ParentId is a reference to the Id in the same table of the parent node. I want to write a query which will build up this string from the table. Is it possible? Thanks

  • Django : debugging templatetags

    - by interstar
    How on earth do people debug Django templatetags? I created one, based on a working example, my new tag looks the same to me as the existing one. But I just get a 'my_lib' is not a valid tag library: Could not load template library from django.templatetags.my_lib, No module named my_lib I know that this is probably because of something failing when defining the lib. But how do I see what's going on? What do you use to debug this situation?

  • App_Code in Web Client Software Factory, Is it a good idea.

    - by Blithe
    Hi guys, Just want to hear some opinion on adding App_Code in Web Client Software Factory (WCSF) project. The main purpose is to put reusable UI rendering codes which can be use by various pages. For WCSF, I guess only controller can share across pages within a module which does not seems to be a good place for UI stuff. Suggestions? :)

  • Help me finish this Python 3.x self-challenge.

    - by Hamish Grubijan
    This is not a homework. I saw this article praising Linq library and how great it is for doing combinatorics stuff, and I thought to myself: Python can do it in a more readable fashion. After half hour of dabbing with Python I failed. Please finish where I left off. Also, do it in the most Pythonic and efficient way possible please. from itertools import permutations from operator import mul from functools import reduce glob_lst = [] def divisible(n): return (sum(j*10^i for i,j in enumerate(reversed(glob_lst))) % n == 0) oneToNine = list(range(1, 10)) twoToNine = oneToNine[1:] for perm in permutations(oneToNine, 9): for n in twoToNine: glob_lst = perm[1:n] #print(glob_lst) if not divisible(n): continue else: # Is invoked if the loop succeeds # So, we found the number print(perm) Thanks!

  • generalizing the pumping lemma for UNIX-style regular expressions

    - by Avi
    Most UNIX regular expressions have, besides the usual *,+,? operators a backslash operator where \1,\2,... match whatever's in the last parentheses, so for example L=(a)b\1* matches the (non regular) language a^n b a^n On one hand, this seems to be pretty powerful since you can create (a*)b\1b\1 to match the language a^n b a^n b a^n which can't even be recognized by a stack automaton. On the other hand, I'm pretty sure a^n b^n cannot be expressed this way. Two questions: 1. Is there any literature on this family of languages (UNIX-y regular). In particular, is there a version of the pumping lemma for these? 2. Can someone prove (or perhaps disprove) that a^n b^n cannot be expressed this way? Thanks

  • Prevent checkins to SVN

    - by Joseph Mastey
    My team uses SVN for our software platform, and we create tags periodically to help keep module versions straight. Best practice, as I understand it, is not to modify a tag once it has been created. However, it seems that sometimes the temptation is too great and a modification is made to one of the tags. Is there a way to prevent these kinds of checkins, or at least make them a complete pain so that we can discourage them automatically? Thanks, Joe

  • Where do I find a good explanation of Javascript-ese

    - by tzenes
    I realize that title may require explanation. The language I first learned was C, and it shows in all my programs... even those not written in C. For example, when I first learned F# I wrote my F# programs like C programs. It wasn't until someone explained the pipe operator and mapping with anonymous functions that I started to understand the F#-ese, how to write F# like a F# programmer and not a C programmer. Now I've written a little javascript, mostly basic stuff using jquery, but I was hoping there was a good resource where I could learn to write javascript programs like a javascript programmer.
