  • Need Regex for to match special situations

    - by Daniel
    I'm desperately searching for regular expressions that match these scenarios: 1) Match alternating chars I've a string like "This is my foobababababaf string" - and I want to match "babababa" Only thing I know is the length of the fragment to search - I don't know what chars/digits that might be - but they are alternating. I've really no clue where to start :( 2) Match combined groups In a string like "This is my foobaafoobaaaooo string" - and I want to match "aaaooo". Like in 1) I don't know what chars/digits that might be. I only know that they will appear in two groups. I experimented using (.)\1\1\1(.)\1\1\1 and things like this...

  • Regex for Date DD-MM-YYYY

    - by Josh M
    I have the following expression which will be used as date validation in the HTML5 "pattern" attribute. ?:0[1-9]|1[0-9]|2[0-9])|(?:(?!02)(?:0[1-9]|1[0-2])-(?:30))|(?:(?:0[13578]|1[02])-31))-(?:(?:0[1-9]|1[0-2])-(?:19|20)[0-9]{2} I want it to allow only valid dates, using "-" as a separator. This means up to 29th in February if it's a leap year, and 30/31 for other months respectively. Currently, it only allows years starting with 2 (2012) and months up to 12 (December). But it limits the day to 29 regardless of which month. Can anybody help me fix it?

  • regex no character

    - by iamnotmad
    In this text: warning here there are several types of warnings in this string warning.gif at the end warning end of line warning I want to match every warning except warning.gif. I cannot seem to get it to include the last one that has no character (control or otherwise) after it. using warnings?[^\.] gets what I want except for the last warning (on the last line). I think because there is no character at all after. How can I get it to include that one?

  • Regex if-else expression

    - by craig
    I'm trying to extract the # of minutes from a text field using Oracle's REGEXP_SUBSTR() function. Data: Treatment of PC7, PT1 on left. 15 min. 15 minutes. 15 minutes 15 mins. 15 mins 15 min. 15 min 15min 15 In each case, I'm hoping to extract the '15' part of the string. Attempts: \d+ gets all of the numeric values, including the '7' and '1', which is undesirable. (\d)+(?=\ ?min) get the '15' from all rows except the last. (?((\d)+(?=\ ?min))((\d)+(?=\ ?min))|\d+), an if-else statement, doesnt' match anything. What is wrong with my if-else statement?

  • Intel Core i5-2467m - Turbo Boost not activating?

    - by Trevor Sullivan
    I have a Samsung Series 5 laptop with an Intel Core i5-2467m process @ 1.6Ghz. The processor supports Intel Turbo Boost up to 2.30 Ghz according to the specifications. The i5-2467m is a dual-core process with HyperThreading, so there is a total of four (4) virtual cores in Windows 7 SP1. http://ark.intel.com/products/56858/ I've installed the Intel Turbo Boost Technology Monitor v2.6 to monitor if Turbo Boost is enabled, and set it to "Always On Top." I followed this process to max out the CPU: Open (4x) PowerShell instances Set each instance's affinity to a distinct CPU vCore Ran this code in each instance: while (1 -eq 1) { } Unfortunately, after maxing out all 4 cores, my laptop got hot, but Turbo Boost never kicked in. Any ideas on how to ensure that I'm getting the 2.3Ghz Turbo Boost capability of my laptop?

  • Copy vector of values to vector of pairs in one line

    - by Kirill V. Lyadvinsky
    I have the following types: struct X { int x; X( int val ) : x(val) {} }; struct X2 { int x2; X2() : x2() {} }; typedef std::pair<X, X2> pair_t; typedef std::vector<pair_t> pairs_vec_t; typedef std::vector<X> X_vec_t; I need to initialize instance of pairs_vec_t with values from X_vec_t. I use the following code and it works as expected: int main() { pairs_vec_t ps; X_vec_t xs; // this is not empty in the production code ps.reserve( xs.size() ); { // I want to change this block to one line code. struct get_pair { pair_t operator()( const X& value ) { return std::make_pair( value, X2() ); } }; std::transform( xs.begin(), xs.end(), back_inserter(ps), get_pair() ); } return 0; } What I'm trying to do is to reduce my copying block to one line with using boost::bind. This code is not working: for_each( xs.begin(), xs.end(), boost::bind( &pairs_vec_t::push_back, ps, boost::bind( &std::make_pair, _1, X2() ) ) ); I know why it is not working, but I want to know how to make it working without declaring extra functions and structs?

  • Linker problem linking boost in Visual Studio 2008

    - by Tobias Langner
    Hi, I have a rather obscure linking problem in Visual Studio 2008. The linker error message is: "LNK1104: cannot open file 'boost_thread-vc90-mt-gd-1_38.lib'". All pathes and dependencies are set. What I noticed though is that Visual Studio misses boost_thread-vc90-mt-gd-1_38.lib and not libboost_thread-vc90-mt-gd-1_38.lib (notice the lib at the beginning of the file name). I added the .lib as libboost_thread-vc90-mt-gd-1_38.lib to the project and it appears as libboost_thread-vc90-mt-gd-1_38.lib in the command line. Why does Visual Studio the beginning of the file name?
