  • 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 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!

  • Append or modify keys in conf files using sed/bash one-liner

    - by Jeff
    I often have to modify files such as sysctl.conf, and I'm familiar with using sed to replace existing values. Is there a way to append the new key/value pair to the file if sed wasn't able to replace it? For instance, using this example: modify config file using bash script sed -c -i "s/\($TARGET_KEY *= *\).*/\1$REPLACEMENT_VALUE/" $CONFIG_FILE How could I add the $TARGET_KEY = $REPLACEMENT_VALUE new line to $CONFIG_FILE using the same sed expression with slight changes? And on a related topic, how can I force creation of $CONFIG_FILE if it didn't exist?

  • 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.

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)

  • Find all <a>s to who's href points to an image with XPath 1.0

    - by Jeffrey Aylesworth
    First, I can assume that all urls that end with jpeg, jpg, bmp, png or gif are images, and others aren't. I thought of, and tried two solutions: Matching the regular expression .(jpe?g|bmp|png|gif)$ Using ends-with to check each separately But, it appears that neither of these exist in XPath 1.0, or at least, they don't exist in Firefox (I am writing a greasemonkey script, so it is only important for the path to work in Firefox).

  • How to achieve an eagerly loaded, filtered child collection with the NHibernate criteria API

    - by vakman
    Is it possible to use the criteria api to load a set of parent objects along with a filtered, eagerly loaded set of child objects? I'm trying to query a list of categories and at the same time load the categories products that start with the letter M. The query below gives me the results I want but the Products are not eagerly loaded, that is NHibernate performs additional queries when I enumerate the Product collection: var categoriesWithProducts = session.CreateCriteria<Category>() .SetFetchMode("Products", FetchMode.Eager) .CreateCriteria("Products") .Add(Expression.Like("Name", "M%")) .List<Category>(); What am I missing here?

  • 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.
