  • Space-based architecture?

    - by rcampbell
    One chapter in Pragmatic Programmer recommends looking at a blackboard/space-based architecture + a rules engine as a more flexible alternative to a traditional workflow system. The project I'm working on currently uses a workflow engine, but I'd like to evaluate alternatives. I really feel like a SBA would be a better solution to our business problems, but I'm worried about a total lack of community support/user base/venders/options. JavaSpaces is dead, and the JINI spin-off Apache River seems to be on life support. SemiSpace looks perfect, but it's a one-man show. The only viable solution seems to be GigaSpaces. I'd like to hear your thoughts on space based architecture and any experiences you've had with real world implementations.

  • Regex - replace only last part of an expression

    I'm attempting to find the best methodology for finding a specific pattern and then replace the ending portion of the pattern. Here is a quick example (in C#): //Find any year value starting with a bracket or underscore string patternToFind = "[[_]2007"; Regex yearFind = new Regex(patternToFind); //I want to change any of these values to x2008 where x is the bracket or underscore originally in the text. I was trying to use Regex.Replace(), but cannot figure out if it can be applied. If all else fails, I can find Matches using the MatchCollection and then switch out the 2007 value with 2008; however, I'm hoping for something more elegant MatchCollections matches = yearFind.Matches(" 2007 [2007 _2007"); foreach (Match match in matches){ //use match to find and replace value }

  • PHP regular expression find and append to string

    - by Gary
    I'm trying to use regular expressions (preg_match and preg_replace) to do the following: Find a string like this: {%title=append me to the title%} Then extract out the title part and the append me to the title part. Which I can then use to perform a str_replace(), etc. Given that I'm terrible at regular expressions, my code is failing... preg_match('/\{\%title\=(\w+.)\%\}/', $string, $matches); What pattern do I need? :/

  • which regular expression will capture this sequence?

    - by John Smith
    The text follows this pattern <tr class="text" (any sequence of characters here, except ABC)ABC(any sequence of characters here, except ABC) <tr class="text" (any sequence of characters here, except ABC)ABC(any sequence of characters here, except ABC) <tr class="text" (any sequence of characters here, except ABC)ABC(any sequence of characters here, except ABC) <tr class="text" (any sequence of characters here, except ABC)ABC(any sequence of characters here, except ABC) so basically the above line might repeat itself multiple times, and the idea is to retrieve the first 3 characters immediately after ABC. I have tried regular expressions along the lines of \<tr class="text" [.]+ABC(?<capture>[.]{3}) but they all fail. Can someone give me a hint?

  • linq-to-sql combine .any expression

    - by Victor
    I need to filter out parent by property value of child collection. I am doing something like this: var results = (from c in db.Customers where c.Orders.Any(o => o.Status = (int)Status.Ordered) select c; It's fine but now I need to filter by 2 values, i.e. take all parent records that have any chilren records that have BOTH values: var results = (from c in db.Customers where c.Orders.Any(o => o.Status == (int)Status.Ordered) && (o.Status == (int).Shipped)) select c; Trying something obvious like this doesn't work.

  • Regular expression to validate a Google Analytics UA Number

    - by Otis
    It's not 100 percent clear to me that the Google Analytics UA Numbers are always 6 digits, a dash, and 2 digits as Google often mentions in their documentation. There are frequent counter-examples that use fewer than 6 for the account portion and 1-4 for the profile. All of the examples always show numbers but it's not even clear that they can't be letters. Does anyone know if Google has published a regex that exactly matches allowable UA Numbers? I'm adding this feature to the admin console of an application I work on and would like to validate the user input.

  • CREATE mysql database with default InnoDB tables?

    - by memilanuk
    Hello, I've been working on writing a SQL statement to create a MySQL database with several default options, including default character set and default collate. Is it possible to add syntax to make the default engine type for tables in this database to be innodb? I've been looking through the MySQL manual for v.5.1 and I've found the statement 'ENGINE=innodb' which would be appended to a CREATE TABLE statement... but I haven't found anything related to a CREATE DATABASE statement. Is there a normal way to do this as part of the database creation, or does it need to be specified on a table-by-table basis? Thanks, Monte

How to implement such rule properly? TIO

  • Treetop basic parsing and regular expression usage

    - by ucint
    I'm developing a script using the ruby Treetop library and having issues working with its syntax for regex's. First off, many regular expressions that work in other settings dont work the same in treetop. This is my grammar: (myline.treetop) grammar MyLine rule line string whitespace condition end rule string [\S]* end rule whitespace [\s]* end rule condition "new" / "old" / "used" end end This is my usage: (usage.rb) require 'rubygems' require 'treetop' require 'polyglot' require 'myline' parser = MyLineParser.new p parser.parse("randomstring new") This should find the word new for sure and it does! Now I wont to extend it so that it can find new if the input string becomes "randomstring anotherstring new yetanother andanother" and possibly have any number of strings followed by whitespace (tab included) before and after the regex for rule condition. In other words, if I pass it any sentence with the word "new" etc in it, it should be able to match it. So let's say I change my grammar to: rule line string whitespace condition whitespace string end Then, it should be able to find a match for: p parser.parse("randomstring new anotherstring") So, what do I have to do to allow the string whitespace to be repeated before and after condition? If I try to write this: rule line (string whitespace)* condition (whitespace string)* end , it goes in an infinite loop. If i replace the above () with [], it returns nil In general, regex's return a match when i use the above, but treetop regex's dont. Does anyone have any tips/points on how to go about this? Plus, since there isn't much documentation for treetop and the examples are either too trivial or too complex, is there anyone who knows a more thorough documentation/guide for treetop?

  • Fuzzy match in sharepoint search engine?

    - by SeeBees
    In sharepoint 2007 sites, we can search for people or other contents. Is the search engine able to do fuzzy match so that "Micheal" can be corrected to "Michael"? If it's possible, does it need extra configuration? I am also writing a custom webpart that uses sharepoint search service, a web service that has url like "http://site/_vti_bin/search.asm". Is it possible to use this service to do fuzzy search as well? Thanks.

  • Nhibernate criteria query inserts an extra order by expression when using JoinType.LeftOuterJoin and Projections

    - by Aaron Palmer
    Why would this nhibernate criteria query produce the sql query below? return Session.CreateCriteria(typeof(FundingCategory), "fc") .CreateCriteria("FundingPrograms", "fp") .CreateCriteria("Projects", "p", JoinType.LeftOuterJoin) .Add(Restrictions.Disjunction() .Add(Restrictions.Eq("fp.Recipient.Id", recipientId)) .Add(Restrictions.Eq("p.Recipient.Id", recipientId)) ) .SetProjection(Projections.ProjectionList() .Add(Projections.GroupProperty("fc.Name"), "fcn") .Add(Projections.Sum("fp.ObligatedAmount"), "fpo") .Add(Projections.Sum("p.ObligatedAmount"), "po") ) .AddOrder(Order.Desc("fpo")) .AddOrder(Order.Desc("po")) .AddOrder(Order.Asc("fcn")) .List<object[]>(); SELECT this_.Name as y0_, sum(fp1_.ObligatedAmount) as y1_, sum(p2_.ObligatedAmount) as y2_ FROM fundingCategories this_ inner join fundingPrograms fp1_ on this_.fundingCategoryId = fp1_.fundingCategoryId left outer join projects p2_ on fp1_.fundingProgramId = p2_.fundingProgramId WHERE (fp1_.recipientId = 6 /* @p0 */ or p2_.recipientId = 6 /* @p1 */) GROUP BY this_.Name ORDER BY p2_.name asc, y1_ desc, y2_ desc, y0_ asc It is incorrectly putting the p2_name asc into the ORDER BY statement, and causing it to crash. This only happens when I use JoinType.LeftOuterJoin on my Projects criteria. Is this a known nhibernate bug? I'm using nhibernate 2.0.1.4000. Thanks for any insight.

  • Moving MVC2 Helpers to MVC3 razor view engine

    - by Dai Bok
    Hi, In my MVC 2 site, I have an html helper, that I use to add javascripts for my pages. In my master page I have the main javascripts I want to include, and then in the aspx pages, I include page specific javascripts. So for example, my Site.Master has something like this: .... <head> <%=html.renderScripts() %> </head> ... //core scripts for main page <%html.AddScript("/scripts/jquery.js") %> <%html.AddScript("/scripts/myLib.js") %> .... Then in the child aspx page, I may also want to include other scripts. ... //the page specific script I want to use <% html.AddScript("/scripts/register.aspx.js") %> ... So when the full page gets rendered the javascript files are all collected and rendered in the head by sitemaster placeholder function RenderScripts. This works fine. Now with MVC 3 and razor view engine, they layout pages behave differently, because now my page level javascripts are not rendered/included. Now all I see the LayoutMaster contents. How do I get the solution wo workwith MVC 3 and the razor view engine. (The helper has already been re-written to return a HTMLString ;-)) For reference: my MasterLayout looks like this: ... ... <head> @{ Html.AddJavaScript("/Scripts/jQuery.js"); Html.AddJavaScript("/Scripts/myLib.js"); } //Render scripts @html.RenderScripts() </head> .... and the child page looks like this: @{ Layout = "~/Views/Shared/MasterLayout.cshtml"; ViewBag.Title = "Child Page"; Html.AddJavaScript("/Scripts/register.aspx.js"); } .... <div>some html </div> Thanks for your help. Edit = Just to explain, if this question is not clear enough. When producing a "page" I collect all the javascript files the designers want to use, by using the html.addJavascript("filename.js") and store these in a dictionary - (1) stops people adding duplicate js files - then finally when the page is ready to render, I write out all the javascript files neatly in the header. (2) - this helper helps keep JS in one place, and prevents designers from adding javascript files all over the place. This used to work fine with Master/SiteMaster Pages in mvc 2. but how can I achieve this with razor?

  • LINQ: Dot Notation vs Query Expression

    - by Martín Marconcini
    I am beginning to use LINQ in general (so far toXML and toSQL). I've seen that sometimes there are two or more ways to achieve the same results. Take this simple example, as far as I understand both return exactly the same thing: SomeDataContext dc = new SomeDataContext(); var queue = from q in dc.SomeTable where q.SomeDate <= DateTime.Now && q.Locked != true orderby (q.Priority, q.TimeCreated) select q; var queue2 = dc.SomeTable .Where( q => q.SomeDate <= DateTime.Now && q.Locked != true ) .OrderBy(q => q.Priority) .ThenBy(q => q.TimeCreated); Besides any mistake I may have made in the syntax or a missing parameter or difference, the idea is that there are two ways to express the same thing; I understand that the first method has some limitations and that the "dot notation" is more complete, but besides that, are there any other advantages?
