Boost::RegEx Syntax issue?
by Timothy H. Schilbach 11 Nov '04

11 Nov '04

Hi Everyone, I have just started using BOOST in my C++ cosing projects as I am a newbie to C++ but very experienced in many other languages. I Needed to write some DLLs for Windows that would allow me to validate the complexity of porposed passwords. I have gotten a simple application togeather and it works very well at this time. The only issue I have is that it isnt validating a match correctly when I use certain RexEx expressions. For example: This expression: ^([a-zA-Z]+)(\d+)([a-zA-Z]+)$ validates strings that start with a character have a digit and then end with a character. This is great and works very well at this time. Now I go to something a bit more complex. I want to validate a new password a user sets and it has to conform to 2 of the following 4 rules: 1. Have uppercase letter 2. Have lower case letter 3. Have 0-9 4. Have a special character !@#$%^&* This RegExs Expression works very well in my other applications written in C# (DOTNET REGex) and also works very well in PERL applications too: (?=\w*[a-z])(?=\w*[A-Z])|(?=\w*\d)(?=\w*[a-z])|(?=\w*[a-z])(?=\w*\d)|(?=\w*[a-z])(?=.*[@#$%^&])|(?=\w*\d)(?=\w*[A-Z])|(?=\w*[A-Z])(?=.*[@#$%^&])|(?=\w*\d)(?=.*[@#$%^&]) Ok I know its a doosy, but I works great everywhere except the application I am running BOOST with. I keep the expression in a registry key so I can edit easily instead of recompiling the DLL if I want to change the RegEx. Here is the code I am using in my C++ project and its failing to validate passwords that match the policies: // Validate password against regular expression wregex wrePassword(DEFAULT_REGEX); WriteToLog("Going to retrieve RegEx from Registry"); GetPasswordRegExFromRegistry(wrePassword); WriteToLog("Going to run match"); // Prepare iterators wstring::const_iterator start = wstrPassword.begin(); wstring::const_iterator end = wstrPassword.end(); match_results<wstring::const_iterator> what; unsigned int flags = match_default; bMatch = regex_match(start, end, what, wrePassword); If all is working corectly the following passwords should pass the RegEx expression I have posted above (it works fiune in PERL or C#/VB.NET) Password Password1 password1 p@ssword Any of those should work just fine and they dont. Anyone able to hep me with this one? Your help is greatly appreciated. I just cant figgure out why a syntax I use in PERL or C#/VB.NET works great but wont work in BOOST. -Timothy

I suppose that means that in the redhat/fedora case these things are already in the path or something? Not that it matters really, just odd that I never had that problem :) -----Original Message----- From: boost-users-bounces(a)lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of paul wisehart Sent: 10 November 2004 13:42 To: boost-users(a)lists.boost.org Subject: Re: [Boost-users] hello world in boost ? OK OK I got it finally ! THanks for your help. Now that I'm looking back its sorta obvious, but I guess I didn;t really now that when you use "-l<some-lib>" with g++ (any compiler?) the its just the name of the physical library in "/usr/local/lib" (or wherever) with the "lib" part cut off. So I was able to get a hello_world.cpp to compile by doing: g++ \ -lboost_regex-gcc \ -L/usr/local/lib \ -I/usr/local/include/boost-1_31 \ hello_world.cpp It was the "-lboost_regex-gcc" part that was tripping me up. I wasn't putting the "-gcc" on the end.

variant.hpp/bind.hpp interaction
by Simmons, Aaron 10 Nov '04

I'm using boost 1.31 with vc7.1. I've found a weird compilation interaction between the boost.bind and boost.variant headers. This code will compile fine: #include "boost/variant.hpp" #include "boost/bind.hpp" But this code won't: #include "boost/bind.hpp" #include "boost/variant.hpp" Here are the errors that are reported: c:\Boost\include\boost-1_31\boost\mpl\less.hpp(39) : error C2760: syntax error : expected ',' not ';' c:\Boost\include\boost-1_31\boost\mpl\less.hpp(51) : see reference to class template instantiation 'boost::mpl::less<T1,T2>' being compiled c:\Boost\include\boost-1_31\boost\mpl\less.hpp(39) : error C2144: syntax error : 'const bool' should be preceded by '}' c:\Boost\include\boost-1_31\boost\mpl\less.hpp(39) : error C2062: type 'const bool' unexpected c:\Boost\include\boost-1_31\boost\mpl\less.hpp(39) : error C2238: unexpected token(s) preceding ';' c:\Boost\include\boost-1_31\boost\mpl\less.hpp(42) : error C2065: 'value' : undeclared identifier

I can tell you that on a fedora/redhat box, you just include the headers and you are away. If you installed the development package group it will be there and you can build c++ programs and use boost out of the box. What distro are you using?

Which library are you wanting to enhance the efficacy of your hello world program with? Most (all?) the boost libs documentation include usage and simple examples.

Lemme ask a simpler question: What the "library" name of boost-regex. Meaning when I compile with g++ from command line, what do I put after the "l"? something like: -lboost or -lboost_regex or -llibboost_regex ? -- paul \ / wisehart >/ <//////$> |\|\|\

ublas compatible solvers (newbie question) (Zrubavel Zodikovich)

Could anyone point me towards boost-compatible implementation of such solver ? thanks in advance ------------------------------ Hello, I know of no such solvers in or out of uBLAS so I am not of much help. However, you may want to consider interfacing uBLAS with libraries which are not compatable with uBLAS. You will find such interfaces in the BOOST-sandbox CVS. I may be undertaking a similar exercise between uBLAS and some sparse system solvers. Also, there exists documentation for these bindings, but I cannot find the link :( Best of luck, Dan

hello world in boost ?

Hi, I am able to compile the boost libaray on my linux machines. I am not able to use it. Is there a simple program I can try to compile to make sure I am doing things correctly. I'm sorry. its a shortcoming of mine, but I can't do _anything_ until I have a working stub. (or hello_world, or wahtever you want to call it.) I just need a simple example of how to compile a boost prohram from g++ . please help me :) -- paul \ / wisehart >/ <//////$> |\|\|\
