  • Way to partialy match a Ruby string using Regexp

    - by Fabiano PS
    I'm working on 2 cases: assume I have those var: a = "hello" b = "hello-SP" b = "not_hello" 1 - Any partial matches I want to accept any string that has the var a inside, so b and c would match. 2 - Patterned match I want to match a string that has a inside, followed by '-', so b would match, c does not. I am having problem, because I always used the syntax /expression/ to define Regexp, so how dinamicaly define an RegExp on Ruby??

  • Checking an empty Core Data relationship (SQLite)

    - by rwat
    I have a to-many relationship in my data model, and I'd like to get all the objects that have no corresponding objects in the relationship. For example: Customer - Purchases I want to get all Customers that have 0 Purchases. I've read somewhere that I could use "Purchases[SIZE] = 0", but this gives me an unsupported function expression error, which I think means it doesn't work with a SQLite backing store (which I don't want to switch from, due to some performance constraints). Any ideas?

  • Haskell: Gluing a char and a list together?

    - by Vincent
    So I have this code here: toWords :: String - [a] toWords "" = [] toWords (nr1 : rest) | nr1 == ' ' = toWords rest | otherwise = nr1 : toWords rest The "toWords" function should simply remove all spaces and return a list with all the words. But I keep getting this error: test.hs:5:18: Couldn't match expected type a' against inferred typeChar' `a' is a rigid type variable bound by the type signature for `toWords' at test.hs:1:22 In the first argument of `(:)', namely `nr1' In the expression: nr1 : toWords rest In the definition of `toWords': toWords (nr1 : rest) | nr1 == ' ' = toWords rest | otherwise = nr1 : toWords rest Failed, modules loaded: none.

  • How to return a whole column with Selenium?

    - by Kymair Wu
    I know that Selenium has a built-in method getTable("tableName.row.column") can return a cell conveniently. However how can I return a whole column? I've tried getText() directly, however only the first cell was returned, getText("//tbody[@id='recordsTable']/tr[contains(@class, 'someclass')]") But getXpathCount() with the same Xpath expression showed there're multiple elements matched. getXpathCount("//tbody[@id='recordsTable']/tr[contains(@class, 'someclass')]") // result is 15 Please kindly help, many thanks!

  • Explicitly accessing banked registers on ARM

    - by Demiurg
    According to the ARM manual, it should be possible to access the banked registers for a specific CPU mode as, for instance, "r13_svc". When I try to do this gcc yells at me with the following error: immediate expression requires a # prefix -- `mov r2,sp_svc' What's wrong?

  • PHP something faster than explode to get filename from URL

    - by FFish
    My URL's can be absolute or relative: $rel = "date/album/001.jpg"; $abs = "http://www.site.com/date/album/image.jpg"; function getFilename($url) { $imgName = explode("/", $url); $imgName = $imgName[count($imgName) - 1]; echo $imgName; } There must be a faster way to do this right? Maybe a reg expression? But that's Chinese to me..

  • DRY up Ruby ternary

    - by Reed G. Law
    I often have a situation where I want to do some conditional logic and then return a part of the condition. How can I do this without repeating the part of the condition in the true or false expression? For example: ClassName.method.blank? ? false : ClassName.method Is there any way to avoid repeating ClassName.method? Here is a real-world example: PROFESSIONAL_ROLES.key(self.professional_role).nil? ? 948460516 : PROFESSIONAL_ROLES.key(self.professional_role)

  • Regex for Eclipse/Flash Builder File Search for comments?

    - by Brian Bishop
    In Eclipse (and Flash/Flex Builder) you get the option with Ctrl+Shift+F to do a file search and look for a regular expression. Would be a real handy thing to know. I want to find the word negate if it appears in a Flex/java comment like the following: // It was negated because or /* The negate option was.... */ or /** * We have to negate the value */ Any ideas? Will test them out at http://www.regexplanet.com/simple/index.html

  • Converting html entities into their values in python

    - by tipu
    I use this regex on some input, [^a-zA-Z0-9@#] However this ends up removing lots of html special characters within the input, such as 227;, #1606;, #1588; (i had to remove the & prefix so that it wouldn't show up as the actual value..) is there a way that I can convert them to their values so that it will satisfy the regexp expression? I also have no idea why the text decided to be so big.

  • Alter a function as a parameter before evaluating it?

    - by Shane
    Is there any way, given a function passed as a parameter, to alter its input parameter string before evaluating it? Here's pseudo-code for what I'm hoping to achieve: test.func <- function(a, b) { # here I want to alter the b expression before evaluating it: b(..., val1=a) } Given the function call passed to b, I want to add in a as another parameter without needing to always specify ... in the b call. So the output from this test.func call should be: test.func(a="a", b=paste(1, 2)) "1" "2" "a"

  • How do I make vim indent java annotations correctly?

    - by wds
    When indenting java code with annotations, vim insists on indenting like this: @Test public void ... I want the annotation to be in the same column as the method definition but I can't seem to find a way to tell vim to do that, except maybe using an indent expression but I'm not sure if I can use that together with regular cindent. edit: The filetype plugin was already turned on I just got a bit confused about indenting plugins. The accepted answer may be a bit hackish but works for me as well.
