  • Is there an easy method to combine two relative paths in C# ?

    - by Ioannis
    I want to combine two relative paths in C#. For example: string path1 = "/System/Configuration/Panels/Alpha"; string path2 = "Panels/Alpha/Data"; I want to return string result = "/System/Configuration/Panels/Alpha/Data"; I can implement this by splitting the second array and compare it in a for loop but I was wondering if there is something similar to Path.Combine available or if this can be accomplished with regular expressions or Linq? Thanks

  • Delete all characters in a multline string up to a given pattern

    - by biffabacon
    Using Python I need to delete all charaters in a multiline string up to the first occurrence of a given pattern. In Perl this can be done using regular expressions with something like: #remove all chars up to first occurrence of cat or dog or rat $pattern = 'cat|dog|rat' $pagetext =~ s/(.*?)($pattern)/$2/xms; What's the best way to do it in Python?

  • Big, Thick Reference Books (PHP / MySQL / Unix) [closed]

    - by Josh K
    I'm looking for in-depth reference books / guides in PHP, MySQL, and Unix. I'm aware there other other questions pertaining to good books for short references of function names, or detailed beginner guides to these systems. I'm looking for something different. I want a book that I can either use as a quick but in-depth (decent write up, not a pocket reference guide) reference to common functions (JOINS, string manipulation, Regular Expressions, etc) while also providing a detailed inner workings explanation on the system itself.

  • Ternary operator in if-statement?

    - by Pindatjuh
    I've written the following if-statement in Java: if(methodName.equals("set" + this.name) || isBoolean() ? methodName.equals("is" + this.name) : methodName.equals("get" + this.name)) { ... } Is this a good practice to write such expressions in if, to separate state from condition? And can this expression be simplified?

  • C# How do I replace an actual asterisk character (*) in a Regex expression?

    - by fraXis
    Hello, I have a statement: I have a string such as content = "* test *" I want to search and replace it with so when I am done the string contains this: content = "(*) test (*)" My code is: content = Regex.Replace(content, "*", "(*)"); But this causes an error in C# because it thinks that the * is part of the Regular Expressions Syntax. How can I modify this code so it changes all asterisks in my string to (*) instead without causing a runtime error? Thanks.

  • Delayed computation as DAG in .NET

    - by Tristan
    I'm playing around with declarative / delayed computation, where expressions are built up into a directed acyclic graph. Microsoft's GPU Accelerator does something similar. Are there any libraries available for .Net languages that makes it easier to build a representation of the computation?

  • Why does ghci say that 1.1 + 1.1 + 1.1 > 3.3 is True?

    - by Frerich Raabe
    I've been going through a Haskell tutorial recently and noticed this behaviour when trying some simple Haskell expressions in the interactive ghci shell: Prelude> 1.1 + 1.1 == 2.2 True Prelude> 1.1 + 1.1 + 1.1 == 3.3 False Prelude> 1.1 + 1.1 + 1.1 > 3.3 True Prelude> 1.1 + 1.1 + 1.1 3.3000000000000003 Does anybody know why that is?

  • php Dollar amount Regular Expression

    - by Thildemar
    I am have completed javascript validation of a form using Regular Expressions and am now working on redundant verification server-side using PHP. I have copied this regular expression from my jscript code that finds dollar values, and reformed it to a PHP friendly format: /\$?((\d{1,3}(,\d{3})*)|(\d+))(\.\d{2})?$/ Specifically: if (preg_match("/\$?((\d{1,3}(,\d{3})*)|(\d+))(\.\d{2})?$/", $_POST["cost"])){} While the expression works great in javascript I get : Warning: preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 1 when I run it in PHP. Anyone have a clue why this error is coming up?

    - by dfjhdfjhdf
    Suppose we don't know how many slashes we could get in a string but we do not want any extra slashes. So if we get this string '/hello/world///////how/are/you//////////////' we should transform it to the form of '/hello/world/how/are/you/'. How to do it with the help of regular expressions in JavaScript?

  • Python PLY zero or more occurrences of a parsing item

    - by None
    I am using Python with PLY to parse LISP-like S-Expressions and when parsing a function call there can be zero or more arguments. How can I put this into the yacc code. This is my function so far: def p_EXPR(p): '''EXPR : NUMBER | STRING | LPAREN funcname [EXPR] RPAREN''' if len(p) == 2: p[0] = p[1] else: p[0] = ("Call", p[2], p[3:-1]) I need to replace "[EXPR]" with something that allows zero or more EXPR's. How can I do this?

  • PHP preg_replace - Very quick question

    - by RC
    Masters of regular expressions, please help! See this string: $string = "http://www.url.com/?fieldA=123&fieldB=456&fieldC=789"; Assuming "fieldB" always has a positive non-decimal numerical value (but not necessarily three digits long), what preg_replace command do I need to remove it completely, such that the string will then read: $string = "http://www.url.com/?fieldA=123&fieldC=789"; Thanks!

  • gcc check if file is main (#if __BASE_FILE__ == __FILE__)

    - by Marcin Raczkowski
    Hello. In ruby there's very common idiom to check if current file is "main" file: if __FILE__ == $0 # do something here (usually run unit tests) end I'd like to do something similar in C after reading gcc documentation I've figured that it should work like this: #if __FILE__ == __BASE_FILE__ // Do stuff #endif the only problem is after I try this: $ gcc src/bitmap_index.c -std=c99 -lm && ./a.out src/bitmap_index.c:173:1: error: token ""src/bitmap_index.c"" is not valid in preprocessor expressions Am I using #if wrong?
