In my velocity template, I want to concat strings delimited by comma(,) using foreach loop.
#foreach($field in $MyObject.Fields)
${field.Name},
#end
This results in an extra comma at the end. How can avoid the last unwanted comma?
PS: I am using NVelocity 0.4.2
Thanks
I can't recall where NVelocity 0.4.2 comes from (i.e. Castle Project or the original port), but if it has the foreach looping directives, you can use them. Take a look at this recently asked question on the same topic:
NVelocity advance lopping syntax
If it doesn't have support for that, you can use the special $velocityCount variable with an #if directive to determine if you want a comma or not.

I have been trying to split a string into an array of each line \n
As this doesn't work I tried replacing replace(outputs('Compose_6'),'\r\n','#') with a view to then splitting on #.
I have searched the internet and tried various things but nothing seems to work.
Can someone explain how to do this?
Thanks in advance
Using split(variables('string var'),'\n') expression, you can split string into array. By default logic app will add an extra black slash to original back slash. So suggesting you to change expression in code view as mentioned above.
I have created logic app as shown below,
In first initialize variable action, taken a string variable with text as shown below
Hello
Test split functionality
Using logic apps
Next initialize variable action, using a array variable and assigning value using expression as split(variables('string var'),'\n'). Make sure you dont have double back slash added in code view. Only one back slash should be there when you see it in code view.
Code view:
The output of logic app can be shown below,

I'm creating a javascript regex to match queries in a search engine string. I am having a problem with alternation. I have the following regex:
.*baidu.com.*[/?].*wd{1}=
I want to be able to match strings that have the string 'word' or 'qw' in addition to 'wd', but everything I try is unsuccessful. I thought I would be able to do something like the following:
.*baidu.com.*[/?].*[wd|word|qw]{1}=
but it does not seem to work.
replace [wd|word|qw] with (wd|word|qw) or (?:wd|word|qw).
[] denotes character sets, () denotes logical groupings.
Your expression:
.*baidu.com.*[/?].*[wd|word|qw]{1}=
does need a few changes, including [wd|word|qw] to (wd|word|qw) and getting rid of the redundant {1}, like so:
.*baidu.com.*[/?].*(wd|word|qw)=
But you also need to understand that the first part of your expression (.*baidu.com.*[/?].*) will match baidu.com hello what spelling/handle????????? or hbaidu-com/ or even something like lkas----jhdf lkja$##!3hdsfbaidugcomlaksjhdf.[($?lakshf, because the dot (.) matches any character except newlines... to match a literal dot, you have to escape it with a backslash (like \.)
There are several approaches you could take to match things in a URL, but we could help you more if you tell us what you are trying to do or accomplish - perhaps regex is not the best solution or (EDIT) only part of the best solution?
I have such a code ng-init="validationRegex = '#RegularExpression.expression'" where RegularExpression.expression is c# string variable = "(\w+\/|\w+\\)+(\w+)\.\w+". I want to pass variable value to angular controller using ng-init. But in the end I get (w+/|w+\)+(w+).w+. How can I get right value?
I assume that your C# code is actually: #"(\w+\/|\w+\\)+(\w+)\.\w+". The # avoids needing the evil escaped escape.
You will likely need to use the evil escaped escape in this case. Note that you don't need to escape the / if you are putting it directly in a string (if you are using it how I think you are). You can also use braces to minimize the escaping. So you can take this regex:
(\w+/|\w+\\)+(\w+)[.]\w+
and pass it through regex planet to get this:
"(\\w+/|\\w+\\\\)+(\\w+)[.]\\w+"
I would not recommend manual conversion since you already have an escaped backslash.
Double escape the string using:
#RegularExpression.expression.Replace(#"\", #"\\")
When it comes through on the JavaScript side it will be singly-escaped again.
I'm creating a custom directive that I want to use to display the value of a field and an optional suffix (expected for units and such). Note that my example is shortened to stay concise.
My template looks something like
<div class="my-value">{{boundValue}}{{boundSuffix}}</div>
For the value, I'm using a two-way binding (=) and for the suffix, I'm using a string binding (&).
It worked great when I bound ° into the suffix to display a temperature, but when I tried to bind in meters (note, there's a leading space - I don't want it pushed up against the number) the leading space seems to get trimmed and my result ends up looking like 123meters.
Using the chrome developer tools, I added a link function and inspected the directive's scope. By the time it reaches the link function, boundSuffix has already been trimmed. It seems like Angular is pulling some shenanigans on my behind the hood. Is there any way for me to avoid this trimming?
It's better to use angular filters to solve your problem. Filters allow to format your output as currency or as UPPERCASE (for example). Try to look here for more info. And here is working example
I cannot seem to find anything about using the values of one property of an object in a foreach loop (without having the entire object placed into the loop).
I first create a function called UFGet-Servers that uses Get-ADComputer and returns the names of the servers in a specific OU in my environment and places them in an array. That's great, except that when I use the array in a foreach loop, each object that it grabs has #[Name=serverName] in it, which I cannot use in any useful manner. The following pseudo-code is an abbreviated example:
foreach($Computer in $ComputerNames){do code... code is adding the server name into a UNC path such as "\\$Computer\C$\"}
The problem with the above is that you can't add the whole object to a path -- it ends up looking like "\#[Name=serverNameHere]\C$\" which totally bombs out. How do I get rid of the "#[property=" part, and simply use the value as the $Computer in the loop?
What really weirds me out is that I can't find a straightforward article on this anywhere... would have thought everyone and their mom would have wanted to do something like this.
So, your issue isn't with ForEach loops, it is with string formatting. There are two ways that I know of to take care of what you need. First is going to be string formatting, which allows you to use {0}m {1} and so on to inject values into a string, providing that you follow the string with -f and a list of said values. Such as:
ForEach($Computer in $ComputerNames){
"The Server Path is \\{0}\Share$" -f $Computer.Name
}
The second way is a sub-expression (I'm sure somebody will correct me if I used the wrong term there). This one involves enclosing the variable and desired property (or a function, or whatever) inside $(). This will evaluate whatever is inside the parenthesis before evaluating the string. See my example:
ForEach($Computer in $ComputerNames){
"The Server Path is \\$($Computer.name)\Share$"
}
