  • How can I convert Perl regular expressions to boost regular expressions?

    - by YY
    I'm not familiar with Perl and boost regular expression and I want to convert a Perl code to c++. I want to convert special regular expression in Perl into c++ using Boost regexp library. Please help me understand what I must do? Here is some regexps that a word of a sentence may match: if ($word =~ /^[\.:\,()\'\`-]/) { # hack for punctuation } if ($word =~ /^[A-Z]/) { return; } if ($word =~ /[A-Za-z0-9]+\-[A-Za-z0-9]+/) { # all hyphenated words return; } if ($word =~ /.*[0-9].*/) { # all numbers return; }

  • List files with two dots in their names using java regular expressions

    - by Nivas
    I was trying to match files in a directory that had two dots in their name, something like theme.default.properties I thought the pattern .\\..\\.. should be the required pattern [. matches any character and \. matches a dot] but it matches both oneTwo.txt and theme.default.properties I tried the following: [resources/themes has two files oneTwo.txt and theme.default.properties] 1. public static void loadThemes() { File themeDirectory = new File("resources/themes"); if(themeDirectory.exists()) { File[] themeFiles = themeDirectory.listFiles(); for(File themeFile : themeFiles) { if(themeFile.getName().matches(".\\..\\..")); { System.out.println(themeFile.getName()); } } } } This prints nothing and the following File[] themeFiles = themeDirectory.listFiles(new FilenameFilter() { public boolean accept(File dir, String name) { return name.matches(".\\..\\.."); } }); for (File file : themeFiles) { System.out.println(file.getName()); } prints both oneTwo.txt theme.default.properties I am unable to find why these two give different results and which pattern I should be using to match two dots... Can someone help?

  • Conditional skin file in ASP.Net Theme based off of browser

    - by Dan Appleyard
    Is there a way to use a skin file in a theme only when a certain browser is used? The theme stays the same, I just want skin A to apply when a certain browser is used, and skin B when another browser is used. I know I can have server-side code to check and then set the SkinId of the control to either or, but is there another, more global way? Thanks

  • How to implement conditional render in JS?

    - by mare
    Below is the JS (jQuery) code of autocomplete's result function. You can see there's some lines where I print out <li>s containing some data properties (that come in as a result of automcomplete's AJAX call). How could I rewrite this so that <li> would be conditionally rendered based on whether the property contains any value being either int or string (not empty string or whitespace) or something else that can be represented as string? $(".clients-dropdown").result(function (event, data, formatted) { if (data) { // set the hidden input that we need for Client entity rematerialize $(".client-id").val(data.client_id); if (data.ClientName && data.Address1 && data.postalcode && data.postname) { $(".client-address").html( "<li>" + data.ClientName + "</li>" + "<li>" + data.Address1 + "</li>" + "<li>" + data.postalcode + " " + data.postname + "</li>" ); $(".client-details").html( "<li>" + data.PrettyId + "</li>" + "<li>" + data.VatNo + "</li>" + "<li>" + data.Phone + "</li>" + "<li>" + data.Mobile + "</li>" + "<li>" + data.Email1 + "</li>" + "<li>" + data.Contact + "</li>" ); } } Also, for the AJAX call, should my server side action return null when there's a null for a property in the database or empty string?

  • Conditional execution of EventTriggers in Silverlight 3

    - by Jason
    I'm currently working on the UI of a Silverlight application and need to be able to change the visual state of a control to one of two possible states based on it's current state when handling the same event trigger. For example: I have a control that sits partially in a clipping path, when I click the visible part of the control I want to change the state to "visible" and if I click it again when it is in its "visible" state I want to change to the "hidden" state. Example XAML: <i:Interaction.Triggers> <i:EventTrigger EventName="MouseLeftButtonUp"> <ic:GoToStateAction StateName="Visible"/> <ic:GoToStateAction StateName="Hidden"/> </i:EventTrigger> </i:Interaction.Triggers> Where "i" is "System.Windows.Interactivity;assembly=System.Windows.Interactivity" and "ic" is "Microsoft.Expression.Interactivity.Core;assembly=Microsoft.Expression.Interactions". I'm currently working in Expression Blend 3 and would prefer to have a XAML only solution but am not opposed to coding this if it is completely necessary. I have tried recording a change in the target state name in Blend but this did not work. Any thoughts on this?

  • Conditional Batch file renaming with mysql data

    - by Paul Stevens
    Hello, I wonder if anyone knows how could I rename multiple files, all of them originally named with same structure, and add some data extracted from a mysql DB according to specifics rules. For example I have 500 files named with this vars: ID NAME ADDRESS PHONE.wav = 1234567 PAULSIMON WESTDR122 9942213456.wav Now I need to rename files taking some data from the databases for each file, and append the data from a query appended to the filename. For example add the data resulting from a query Where some conditions match, and the data to build the query is taked from original file name, as ID or NAME. i other words, lets say that I want to build a query taking ID & NAME from file 1234567 PAULSIMON WESTDR123 9942213456.wav as WHERE statements to take another value as BirthDATE and add this to new filename, so final result should be: ID NAME ADDRESS PHONE BIRTHDATE.wav I will appreciate any help on this. I need this to be done on a LINUX server.

  • TextMate: Conditional formatting?

    - by Nebs
    I want to be able to color lines differently based on the starting character. eg.: - This is line 1 - This is line 2 x This is line 3 - This is line 4 x This is line 5 So lines 1,2,4 (starting with '-') should be blue while lines 3,5 (starting with 'x') should be red. Is this possible? How would you do it? Thanks.

  • C++ conditional compilation

    - by Shaown
    I have the following code snippet #ifdef DO_LOG #define log(p) record(p) #else #define log(p) #endif void record(char *data){ ..... ..... } Now if I call log("hello world") in my code and DO_LOG isn't defined, will the line be compiled, in other words will it eat up the memory for the string "hello world"? P.S. There are a lot of record calls in the program and it is memory sensitive, so is there any other way to conditionally compile so that it only depends on the #define DO_LOG? Thanks in advance.

  • The shortest way to convert infix expressions to postfix (RPN) in C

    - by kuszi
    Original formulation is given here (you can try also your program for correctness) . Additional rules: 1. The program should read from standard input and write do standard output. 2. The program should return zero to the calling system/program. 3. The program should compile and run with gcc -O2 -lm -s -fomit-frame-pointer. The challenge has some history: the call for short implementations has been announced at the Polish programming contest blog in September 2009. After the contest, the shortest code was 81 chars long. Later on the second call has been made for even shorter code and after the year matix2267 published his solution in 78 bytes: main(c){read(0,&c,1)?c-41&&main(c-40&&(c%96<27||main(c),putchar(c))):exit(0);} Anyone to make it even shorter or prove this is impossible?

  • Conditional row count in linq to nhibernate doesn't work

    - by Lucasus
    I want to translate following simple sql query into Linq to NHibernate: SELECT NewsId ,sum(n.UserHits) as 'HitsNumber' ,sum(CASE WHEN n.UserHits > 0 THEN 1 ELSE 0 END) as 'VisitorsNumber' FROM UserNews n GROUP BY n.NewsId My simplified UserNews class: public class AktualnosciUzytkownik { public virtual int UserNewsId { get; set; } public virtual int UserHits { get; set; } public virtual User User { get; set; } // UserId key in db table public virtual News News { get; set; } // NewsId key in db table } I've written following linq query: var hitsPerNews = (from n in Session.Query<UserNews>() group n by n.News.NewsId into g select new { NewsId = g.Key, HitsNumber = g.Sum(x => x.UserHits), VisitorsNumber = g.Count(x => x.UserHits > 0) }).ToList(); But generated sql just ignores my x => x.UserHits > 0 statement and makes unnecessary 'left outer join': SELECT news1_.NewsId AS col_0_0_, CAST(SUM(news0_.UserHits) AS INT) AS col_1_0_, CAST(COUNT(*) AS INT) AS col_2_0_ FROM UserNews news0_ LEFT OUTER JOIN News news1_ ON news0_.NewsId=news1_.NewsId GROUP BY news1_.NewsId How Can I fix or workaround this issue? Maybe this can be done better with QueryOver syntax?

  • Regular expressions in c++ STL

    - by Radek Šimko
    Is there any native library in STL which is tested and works without any extra compiler options? I tried to use <regex>, but the compiler outputs this: In file included from /usr/include/c++/4.3/regex:40, from main.cpp:5: /usr/include/c++/4.3/c++0x_warning.h:36:2: error: #error This file requires compiler and library support for the upcoming ISO C++ standard, C++0x. This support is currently experimental, and must be enabled with the -std=c++0x or -std=gnu++0x compiler options.

  • jquery reset conditional filter

    - by VictorS
    I have 2 dropdown lists on my webform and using jquery trying to filter/reset filter 2nd dropdown elements based on 1st dropdown selection. $(document).ready(function() { $('#dropdown1').change(function(e) { switch ($(this).val()) { case "4": //this removal works $('#dropdown2').filter(function() { return ($(this).val() == 16); }).remove(); break; ................. default: //how would I restore filter here? } } }); Removing part works, so it filters item with no problem, but I have difficulty restoring the filter on dropdown 2 if something else is chosen in dropdown 1. I was trying to use .hide() and .show() instead of .remove() but it doesn't seem to work on IE6 at least.

  • perl regular expressions substitution/replacement using variables with special characters

    - by user961627
    Okay I've checked previous similar questions and I've been juggling with different variations of quotemeta but something's still not right. I have a line with a word ID and two words - the first is the wrong word, the second is right. And I'm using a regex to replace the wrong word with the right one. $line = "ANN20021015_0104_XML_16_21 A$xAS A$xASA"; @splits = split("\t",$line); $wrong_word = quotemeta $splits[1]; $right_word = quotemeta $splits[2]; print $right_word."\n"; print $wrong_word."\n"; $line =~ s/$wrong_word\t/$right_word\t/g; print $line; What's wrong with what I'm doing? Edit The problem is that I'm unable to retain the complete words - they get chopped off at the special characters. This code works perfectly fine for words without special characters. The output I need for the above example is: ANN20021015_0104_XML_16_21 A$xASA A$xASA But what I get is ANN20021015_0104_XML_16_21 A A Because of the $ character.

  • Lambda expressions and nullable types

    - by Mathew
    I have two samples of code. One works and returns the correct result, one throws a null reference exception. What's the difference? I know there's some magic happening with capturing variables for the lambda expression but I don't understand what's going on behind the scenes here. int? x = null; bool isXNull = !x.HasValue; // this works var result = from p in data.Program where (isXNull) select p; return result.Tolist(); // this doesn't var result2 = from p in data.Program where (!x.HasValue) select p; return result2.ToList();

  • Are Conditional subquery

    - by Tobias Schulte
    I have a table foo and a table bar, where each foo might have a bar (and a bar might belong to multiple foos). Now I need to select all foos with a bar. My sql looks like this SELECT * FROM foo f WHERE [...] AND ($param IS NULL OR (SELECT ((COUNT(*))>0) FROM bar b WHERE f.bar = b.id)) with $param being replaced at runtime. The question is: Will the subquery be executed even if param is null, or will the dbms optimize the subquery out?

  • Conditional SELECT MySQL

    - by user188693
    Don't know if this is possible, but I'd like to select records based on the field value of recur_type, where the 'm' is the day of the week. If it's a weekly recurring event, I need to make sure this is a day it recurs on, otherwise, I want to return all days. however, I'm getting an empty result set: SELECT * FROM wp_fun_bec_events WHERE start_date <= '2009-10-12' AND ( end_date >= '2009-10-12' OR (recur_end > '0' AND recur_end >= '2009-10-12' ) ) AND ('m' IN ( CASE WHEN 'recur_type' = 'weekly' THEN recur_days ELSE 's/m/t/w/r/f/a' END ) ) ORDER BY start_date, start_time Any ideas??

  • Cron expressions: leading zeros ok?

    - by JimBurnell
    A quartz-scheduled process did not kick off last evening. The only thing that looks like it MIGHT be off is that, in one entry: 0 00 23 13,15 APR ? The "minutes" field is specified as a 2-digit 00 rather than a single-digit 0. I can't find any definitive cron documentation saying whether or not this would cause a problem. I can't test it again until the off-hours. Anyone know for sure if this could be a problem? if so, it's rather a silly one.

  • How to create a conditional measure in SQL Server 2008 Analysis services

    - by Jonathan
    Hi there I am not sure if the title has the correct terms, I have a developer and am very new to cubes. I have a cube which has data associated to materials that are broken down into chemical compounds. For example a rock material has 10% of this chemical and 10% of that chemical, etc. Samples are taken daily and sample is a dimension with date, etc. So, the measure needs to average by the sample dimension but needs to sum across the chemical compound dimension (To add up to 100% for example). Is this at all possible?

The span_col attribute in the first 'BANNER_TEXT' sequence indicates which elements by position in the 2nd sequence are related. An example: 'Years in Practice' would be the first key and the attribute SPAN_COL=3 for that element indicates it would contain '< 11 years', '11-20 years', '21-30 years' (the first grouping of string.empty = Total would be skipped).

  • Conditional directive to identify C++ Builder personalities

    - by Narcís Calvet
    Hello, I have a Delphi component which I want to install and have it available at the component palette in Delphi but not in C++ Builder. In BDS/RAD 2006 and above I can either have it installed for both personalities or none. I need to do so because this component uses 3rd party libraries that doesn't support C++ Builder. I have looked at jedi.inc mentioned here but I'm not able to find the combination to be able to register the component in Delphi personalities only. The component should also work for D5, D6 and D7 but not for BCB5 and BCB6. Is this possible? BTW: Component is written in Delphi. C++ Builder shares same packages as Delphi. Thanks in advance.
