  • C# Regular Expression for Regular Expression Parsing

    - by Chris
    I want to returns matches from a regular expression string. The regex string is: (?<TICKER>[A-Z]+)(?<SPACE>\\s)(?<MONTH_ALPHA_ABBREV>Jan|Feb|Mar|Apr|May|Jun|Jul|Sep|Oct|Nov|Dec)(?<SPACE>\\s)(?<DAY>\\d+)(?<SPACE>\\s)(?<YEAR_LONG>[2][0][0-9][0-9])(?<SPACE>\\s)(?<STRIKE_DOLLAR>\\d+(?=[.]))[.](?<STRIKE_DECIMAL>(?<=[.])\\d+)(?<SPACE>\\s)(?<PUTCALL_LONG>Call|Put) And I want to get matches for all of the group names and all of the items within square brackets (including the square brackets) outside of open and closed parenthesis. I have this regex: ((?<=[<])([A-Z]|[_])+(?=[>]))|(\\[.\\]) But this returns square bracket items within the parenthesis. To be more specific these are the matches I want from the regex at the top (keep in mind this needs to be flexible for any regex): TICKER SPACE MONTH_ALPHA_ABBREV SPACE DAY SPACE YEAR_LONG SPACE STRIKE_DOLLAR [.] STRIKE_DECIMAL SPACE PUTCALL_LONG

  • Mixing regular expression and other conditional expression in a bash if statement

    - by Tassos
    I can't get around this for quite sometime now. As I read along manuals and tutorials I'm getting more confused. I want an if statement with the following logic: if [ -n $drupal_version ] && [[ "$drupal_version" =~ DRUPAL-[6-9]-[1-9][1-9] ]]; then but I can't get it to work properly. When the script is evaluated using the "bash -x ... " script construct, works ok but when is run as a regular script my expression is not evaluated (eventhough the above condition should be met the else part is run). Could you provide any help?

  • How to use Common Table Expression and check no duplication in SQL Server

    - by vodkhang
    I have a table references to itself. User table: id, username, managerid and managerid links back to id Now, I want to get all the managers including direct manager, manager of direct manager, so on and so forth... The problem is that I do not want to have a unstop recursive sql. So, I want to check if an id alreay in a list, I will not include it anymore. Here is my sql for that: with all_managers (id, username, managerid, idlist) as ( select u1.id, u1.username, u1.managerid, ' ' from users u1, users u2 where u1.id = u2.managerid and u2.id = 6 UNION ALL select u.id, u.username, u.managerid, idlist + ' ' + u.id from all_managers a, users u where a.managerid = u.id and charindex(cast(u.id as nvarchar(5)), idlist) != 0 ) select id, username from all_managers; The problem is that in this line: select u1.id, u1.username, u1.managerid, ' ' The SQL Server complains with me that I can not put ' ' as the initialized for idlist. nvarchar(40) does not work as well. I do not know how to declare it inside a common table expression like this one. Usually, in db2, I can just put varchar(40) My sample data: ID UserName ManagerID 1 admin 1 2 a 1 3 b 1 4 c 2 What I want to do is that I want to find all managers of c guy. The result should be: admin, a, b. Some of the user can be his manager (like admin) because the ManagerID does not allow NULL and some does not have direct manager. With common table expression, it can lead to an infinite recursive. So, I am also trying to avoid that situation by trying to not include the id twice. For example, in the 1st iteration, we already have id : 1, so, in the 2nd iteration and later on, 1 should never be allowed. I also want to ask if my current approach is good or not and any other solutions? Because if I have a big database with a deep hierarchy, I will have to initialize a big varchar to keep it and it consumes memory, right?

  • Best practice Java - String array constant and indexing it

    - by Pramod
    For string constants its usual to use a class with final String values. But whats the best practice for storing string array. I want to store different categories in a constant array and everytime a category has been selected, I want to know which category it belongs to and process based on that. Addition : To make it more clear, I have a categories A,B,C,D,E which is a constant array. Whenever a user clicks one of the items(button will have those texts) I should know which item was clicked and do processing on that. I can define an enum(say cat) and everytime do if clickedItem == cat.A .... else if clickedItem = cat.B .... else if .... or even register listeners for each item seperately. But I wanted to know the best practice for doing handling these kind of problems.

  • .NET Expression Trees Tutorial

    - by zoman
    I've been looking for a good tutorial on Expression trees (C#) for a while, but no luck so far. Most of the stuff I've found on the Web was too high level and very basic. Does anyone know some decent tutorial that goes beyond the fundamentals?

  • Users need Silverlight 4.0 for Expression Blend?

    - by Mohit Deshpande
    I have Visual Studio 2010 beta 2 installed and Expression Blend Preview for .NET 4. When I began to debug it, it asked me to install Silverlight 4.0 beta. So now I am wondering if people who are going to view my application need to install Silverlight 4.0 instead of Silverlight 3.5. If so, how can I downgrade from 4.0 to 3.5?

  • Built-in precedence in Expression Trees for math?

    - by jdk
    I'm unable to find the .NET FCL built-in concept of precedence to leverage while constructing Expression Trees. Ref System.Linq.Expressions Namespace. Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it (e.g. maybe through helper methods or classes)? I want to apply it to math operations to ensure 3 + 5 * 10 results in 53 instead of 80.

  • regular expression

    - by Jeeenda
    Hi I need a regular expression that'll give me something like this part ./something\", [something.sh from something like this string ("./something\", [something.sh", ["./something\", [something.sh"], [/* 37 vars */]) is that possible? I'm having real trouble making this since there's that \" escape sequence and also that ',' character, so I cannot simply use match everything instead of these characters. I'm working on unix so it's also possible to use pipeline of few greps or something like that. Thanks for advice.

  • How to style a treeview in Expression Blend

    - by RobDemo
    (Using Expression Blend 4 RC, Silverlight 3) I have a treeview with several different item templates for different levels. When I open this project in Blend, it seems I can only really style the top-most DataTemplate (via right-click the TreeView in the Objects/Timeline view, Edit Additional Templates-Edit Generated Items (ItemTemplate) - Edit Current). How do I drill down into the level I want and edit those templates? Rob

  • Tutorials and Introductions to C++ Expression Templates

    - by grrussel
    What are good introductions to the creation of C++ expression template systems? I would like to express arithmetic on user defined types while avoiding temporary values (which may be large), and to learn how to do this directly rather than applying an existing library. I have found Todd Veldhuizen's original paper and an example from the Josuttis C++ Templates book, and an article by Kreft & Langer. I am looking for simple, clear expositions.
