• Regex to use each letter only once?

  - by gtcaz

  Is it possible to construct a PCRE-style regular expression that will only match each letter in a list only once? For example, if you have the letters "lrsa" and you try matching a word list against: ^[lrsa]*m[lrsa]*$ you're going to match "lams" (valid), but also "lamas" (invalid for our purposes because you only had one "a"). If your letter set was "lrsaa", you would want to match "lamas". Is this possible with regular expressions, or should I handle it programmatically?

• Need to add underscore to my regex

  - by TaMeR

  I suck at regular expression and just can't seem to figure this out. '/^[A-Za-z0-9](?:.[A-Za-z0-9]+)*$/' As it's right now it allows dots anytime after the first char and I like to add _ so that it allows both. Thanks

• How to parse a midlet JAD file in C#?

  - by codemonkie

  Besides doing it manually using regular expression search, is there other better ways to parse a JAD file? I need to be able to search for and replace/insert a new MIdlet-Install-Notify property to a JAD file given, also updating the value of the MIDlet-Jar-URL property. Using ANTLR or TinyPG is a bit overkill for my case. TIA

• In what situation should the built-in 'operator' module be used in python?

  - by apphacker

  I'm speaking of this module: http://docs.python.org/library/operator.html From the article: The operator module exports a set of functions implemented in C corresponding to the intrinsic operators of Python. For example, operator.add(x, y) is equivalent to the expression x+y. The function names are those used for special class methods; variants without leading and trailing __ are also provided for convenience. I'm not sure I understand the benefit or purpose of this module.
