  • regular expression for letters, numbers and - _ .

    - by Jorre
    I'm having trouble checking in PHP if a value is is any of the following combinations letters (upper or lowercase) numbers (0-9) underscore (_) dash (-) point (.) no spaces! or other characters a few examples: OK: "screen123.css" OK: "screen-new-file.css" OK: "screen_new.js" NOT OK: "screen new file.css" I guess I need a regex for this, since I need to throw an error when a give string has other characters in it than the ones mentioned above.

    Been trying to solve this for a while now. I need a regex to strip the newlines, tabs and spaces between the html tags demonstrated in the example below: Source: <html> <head> <title> Some title </title> </head> </html> Wanted result: <html><head><title>Some title</title></head></html> The trimming of the whitespaces before the "Some title" is optional. I'd be grateful for any help

  • Buggy Perl regular expression

    - by Tichomir Mitkov
    Hi, there I'm writing a program that has to get values from a file. In the file each line indicates an entity. Each entity has three values. For example: Value1 Value2 value3 I have a regular expresion to match them m/(.*?) (.*?) (.*?)/m; But it seems that the third value in never matched! The only way to match the third value is to add another value in the file and another "matching brackets" in the expresion. But this does not satisfy me. Thanks in Advance!

  • Any good lightweight date/time picker for web with good UI ?

    - by nexneo
    Few wishes, If it is jQuery based, best. If it focus easy UI then eye candy, better. If it is date and time picker both, good. Edit: I should have mentioned , I already looked most options available that I can found using google. Problem is not a single date+time picker is part of official jquery-ui project so some are for old jquery version. some have ugly UI choices. One which have somewhat good UI seems buggy.

  • What to keep in mind when creating your own custom web services API?

    - by John Conde
    I have created a website which allows users to sign up for, and use, an online service. To help promote the website we will be have resellers who will be offering their own branded services through us. The initial plan is to allow resellers to place registration, login, and lost password forms on their own website and use an API created by us to handle these requests. I have begun outlining how I expect the API to work (and starting documenting it as well) and I want to make sure I get it right, or as close to right, as I can from the beginning as I know once you have declared a public API you want to avoid changing that API at all costs. So far I have decided: To have the user pass their account credentials with each request To require SSL for all requests What else should I be keeping in mind?

  • SFINAE + sizeof = detect if expression compiles

    - by FredOverflow
    I just found out how to check if operator<< is provided for a type. template<class T> T& lvalue_of_type(); template<class T> T rvalue_of_type(); template<class T> struct is_printable { template<class U> static char test(char(*)[sizeof( lvalue_of_type<std::ostream>() << rvalue_of_type<U>() )]); template<class U> static long test(...); enum { value = 1 == sizeof test<T>(0) }; typedef boost::integral_constant<bool, value> type; }; Is this trick well-known, or have I just won the metaprogramming Nobel prize? ;) EDIT: I made the code simpler to understand and easier to adapt with two global function template declarations lvalue_of_type and rvalue_of_type.

  • What are the most active Ruby forums/blogs on the web?

    - by MOZILLA
    I have just spent 2 days with Ruby, and my observation in last two days is that it is very difficult (as compared to say .NET/Java) to find an active forum/blogs which are helpful for Ruby (or maybe I don't know them since I am new). Which are the most common forums/blogs developers visit when they need help with Ruby (other than Stack Overflow)?

  • string substitution regular expression not working in tcl

    - by Puneet Mittal
    i am trying to replace all the special characters including white space, hyphen, etc, to underscore, from a string variable in tcl. I wrote the code below but it doesn't seem to be working. set varname $origVar puts "Variable Name :>> $varname" if {$varname != ""} { regsub -all {[\s-\]\[$^?+*()|\\%&#]} $varname "_" $newVar } puts "New Variable :>> $newVar" one issue is that, instead of replacing the string in $varname, it is replacing the data inside $origVar. No idea why, and also i read the example code (for proper syntax) in my tcl book and according to that it should be something like this regsub -all {[\s-][$^?+*()|\\%&#]} $varname "_" newVar so i used the same syntax but it didn't work and gave the same result as modifying the $origVar instead of required $varname value.

  • Are there any web application frameworks usable with .NET 2.0?

    - by adhocgeek
    Apologies if this has been asked many, many times before - I'm afraid I couldn't find any satisfactory answers. I'm stuck in an environment (a bank) where, although we have VS 2008 on the development machines, production machines are locked down to the .Net framework 2.0 and SQL Server 2005. Are there any modern application frameworks that I could employ? I've looked at things like Spring.NET, PureMVC and ASP.NET MVC (S#arp Arch?), but I don't really have the luxury of time to investigate in depth. I don't want to initiate a war over which framework might be best, I just want to know if there are any I can actually use.

  • regular expression and escaping

    - by pstanton
    Sorry if this has been asked, my search brought up many off topic posts. I'm trying to convert wildcards from a user defined search string (wildcard is "*") to postgresql like wildcard "%". I'd like to handle escaping so that "%" => "\%" and "\*" => "*" I know i could replace \* with something else prior to replacing * and then swap it back, but i'd prefer not to and instead only convert * using a pattern that selects it when not proceeded by \. String convertWildcard(String like) { like = like.replaceAll("%", "\\%"); like = like.replaceAll("\\*", "%"); return like; } Assert.assertEquals("%", convertWildcard("*")); Assert.assertEquals("\%", convertWildcard("%")); Assert.assertEquals("*", convertWildcard("\*")); // FAIL Assert.assertEquals("a%b", convertWildcard("a*b")); Assert.assertEquals("a\%b", convertWildcard("a%b")); Assert.assertEquals("a*b", convertWildcard("a\*b")); // FAIL ideas welcome.

  • dynamic xpath expression

    - by Ferol
    Good day, colleagues! Tell me please, how to make a dynamic xpath-parsing: for example, instead of writing $domXPath-query('//[(@id = "article-id-18")]'); - write something like that $domXPath-query('//[(@id = "article-id-*")]');, because in my case, the site's script generate (every time) a new id for block, that contains article's text? So question, is above.

  • Can the traditional remote desktop client be accessed in Windows RT?

    - by nhinkle
    As mentioned in another question, I've been unable to connect through the Remote Desktop metro app to some computers, in particular those requiring VPN access or load balancers. I'm considering purchasing a Microsoft Surface RT, but given that the app store hasn't matured significantly yet and some niche software will likely never be ported to the Modern UI, I must have acess to remote systems somehow. Until Citrix fixes the receiver app for Windows 8, I'm stuck using remote desktop. Which doesn't work. I've heard that Windows RT comes with some of the Microsoft desktop programs built in, like Microsoft Office and File Explorer. Is the "normal" Remote Desktop Connection program available in Windows RT, and if so, is it 100% compatible with previous versions?

    - by Brian Heylin
    I'm trying to match on an option group in Scala 2.8 (beta 1) with the following code: import scala.xml._ val StatementPattern = """([\w\.]+)\s*:\s*([+-])?(\d+)""".r def buildProperty(input: String): Node = input match { case StatementPattern(name, value) => <propertyWithoutSign /> case StatementPattern(name, sign, value) => <propertyWithSign /> } val withSign = "property.name: +10" val withoutSign = "property.name: 10" buildProperty(withSign) // <propertyWithSign></propertyWithSign> buildProperty(withoutSign) // <propertyWithSign></propertyWithSign> But this is not working. What is the correct way to match optional regex groups?

  • How can I paste an image from the clipboard into a web form?

    - by dr. squid
    I found this question, but the question is about how to get an image from the clip board into a wyziwyg editor! My question is "How can I paste an image from the clipboard into a field (what field is not that big issue as long as it works)", and then sent to the server. Jira has this functionality, so it should be possible! Any ideas on how to do this? Just to explain the complete workflow; I would like to have a plave to multi upload images, where the paste from clipboard also is an option. The upload will be some ajax of some sort, bt is not important in this context! Thanks
