I am trying to add some string values to a list in Velocity. When I run the code it works alright. But the line where it adds the value prints true. Is it always like that in Velocity? I am new to Velocity templates, so cant figure it out myself.
#set ($uniqueInterfaces = [])
#if($ipv4interfaceName == $ipv6interfaceName)
$uniqueInterfaces.add($ipv4interfaceName)
#end
Its part of larger code with a nested foreach. It has two matches in it, so the output is:
true
true
I do not need this true being printed at all!
Java's List#add method returns boolean, that's why this return value is printed in your html output.
You can hide it simply by assigning the output of the add method to a dummy variable:
#set ($uniqueInterfaces = [])
#if($ipv4interfaceName == $ipv6interfaceName)
#set ($swallow = $uniqueInterfaces.add($ipv4interfaceName))
#end

I'm new to Velocity scripting and made a few simple scripts and they work ok.
I'm now trying something else, which should be simple but I can't seem to get it to work.
I'm selecting a bunch of Work Items, reading a custom field (NumberPack) and I just want to sum them.
My script is as follow:
#set($PCR = $transaction.workItems.search.query("type:Paramrequest AND created:[20220101 TO 30000000] AND NumberPack.1:[00000000001 TO 02147483647]"))
#set($Total = 0)
#set($Pack = 0)
#set($x = 0)
#foreach($PCR in $PCR)
##set($Pack = $Pack.parseInt($PCR.fields.get("NumberPack")))
##set($x = $Total.add($Pack))
$PCR.fields.get("NumberPack").render ## this renders each NumberPack of each WI
#set($Pack = $PCR.fields.get("NumberPack"))
##set($x = $Total2.add($PCR.fields.get("NumberPack")))
##set($Total2 = $Total2 + 1)
#set($x = $math.add($x, 1))
#end
<br> Total: $Total
<br> $x
As you can see I tried a few methods but I keep getting the total 0.
Any ideas what I'm doing wrong?
Thanks
If you write
#set($Pack = $PCR.fields.get("NumberPack"))
Pack: $Pack <br>
the output is something like:
Pack: com.polarion.alm.server.api.model.fields.ProxyIntegerField#67807d51
In the API Javadoc (https://almdemo.polarion.com/polarion/sdk/doc/javadoc-rendering/com/polarion/alm/shared/api/model/fields/IntegerField.html), you'll find that api.model.fields IntegerField has a get() method, which gives you the value. Though I agree this is never explicitly stated in the documentation.
You need to write
#set($Pack = $PCR.fields.get("NumberPack").get())
to get the value. The following statement will give you the cumulative sum.
#set($Total = $math.add($Total, $PCR.fields.get("NumberPack").get()))
Also be careful with your #foreach statement. In this case it seems to work, but it would be safer to give your iterator variable a name differing from the collection you are iterating through. For example:
#foreach($PCR in $PCRs)
I'm trying to save just a number from a string I get from a paragraph but when I try to asign an alias to it and then check the value it returns undefined. I've tried a few solutions I found but none of those seem to work for me. These are two ways I tried (I tried another one similar to the second one but using split, had same result). The console.log inside of the 'then' doesn't show in the console, and when I try the alias after the code is when I get undefined.
cy.get('p')
.eq(1)
.should('have.text', '/[0-9]+/g')
.as('solNumber')
cy.get('p')
.eq(1)
.invoke('text')
.then((text)=>{
var fullText = text;
var pattern = /[0-9]+/g;
var number = fullText.match(pattern);
console.log(number);
})
.as('solNumber')
Please convert with + operator and return the numeric value if you want numeric type to be stored.
cy.get('p').eq(1)
.invoke('text')
.then(fullText => {
const number = fullText.match(/[0-9]+/);
return +number // text to numeric
})
.as('solNumber')
cy.get('#solNumber')
.should('eq', 42) // numeric type
});
Running your 2nd code on this,
<p>21</p>
<p>42</p>
gives the correct outcome
cy.get('p')
.eq(1)
.invoke('text')
.then((text)=>{
var fullText = text;
var pattern = /[0-9]+/g;
var number = fullText.match(pattern);
console.log(number); // logs 42
})
.as('solNumber')
cy.get('#solNumber')
.should('eq', '42') // passes
So, you need to inspect the DOM, it looks like it's not what you expect.
The first attempt you were passing a jquery element to the .should() and although some chainers change the subject yours did not so it saved the jquery element as solNumber.
The second attempt invokes the .text() which was passed to the .then() it logs the number correctly. However, you did not return anything at the end of the .then() block, therefore, solNumber should hold the entire paragraph.
This should help you out to extract the specific number and save it as an alias.
cy.get('p')
.invoke('text')
.invoke('trim')
.then(paragraph => {
const matcher = /some/
expect(paragraph).to.match(matcher) // check number is there
const indexOfText = paragraph.match(matcher) // get index of match text
return paragraph.substring(indexOfText.index, indexOfText.index + indexOfText[0].length) // return substring
})
.as('savedText')
cy.get('#savedText')
.then(cy.log) // will print out the number you seek
I have been looking for a solution everywhere on the internet but nowhere I can see a single script which lets me read the name of a variable as a string in Godot 3.1
What I want to do:
Save path names as variables.
Compare the name of the path variable as a string to the value of another string and print the path value.
Eg -
var Apple = "mypath/folder/apple.png"
var myArray = ["Apple", "Pear"]
Function that compares the Variable name as String to the String -
if (myArray[myposition] == **the required function that outputs variable name as String**(Apple) :
print (Apple) #this prints out the path.
Thanks in advance!
I think your approach here might be a little oversimplified for what you're trying to accomplish. It basically seems to work out to if (array[apple]) == apple then apple, which doesn't really solve a programmatic problem. More complexity seems required.
First, you might have a function to return all of your icon names, something like this.
func get_avatar_names():
var avatar_names = []
var folder_path = "res://my/path"
var avatar_dir = Directory.new()
avatar_dir.open(folder_path)
avatar_dir.list_dir_begin(true, true)
while true:
var avatar_file = avatar_dir.get_next()
if avatar_file == "":
break
else:
var avatar_name = avatar_file.trim_suffix(".png")
avatar_names.append(avatar_name)
return avatar_names
Then something like this back in the main function, where you have your list of names you care about at the moment, and for each name, check the list of avatar names, and if you have a match, reconstruct the path and do other work:
var some_names = ["Jim","Apple","Sally"]
var avatar_names = get_avatar_names()
for name in some_names:
if avatar_names.has(name):
var img_path = "res://my/path/" + name + ".png"
# load images, additional work, etc...
That's the approach I would take here, hope this makes sense and helps.
I think the current answer is best for the approach you desire, but the performance is pretty bad with string comparisons.
I would suggest adding an enumeration for efficient comparisons. unfortunately Godot does enums differently then this, it seems like your position is an int so we can define a dictionary like this to search for the index and print it out with the int value.
var fruits = {0:"Apple",1:"Pear"}
func myfunc():
var myposition = 0
if fruits.has(myposition):
print(fruits[myposition])
output: Apple
If your position was string based then an enum could be used with slightly less typing and different considerations.

Can't you just use the str() function to convert any data type to stirng?
var = str(var)
I am new to apache velocity, I want to create a subList Object from the List Objects which are coming from some service call in .vm file.
We need to render the list based on some logic in parts, for that we want to create sublist from list.
$table.getBooks() //contains all the Books objects
Below is the sample code which I tried but it did not work.
#set($segregatedList = [])
#set($size = $table.getLineItems().size())
#foreach($index in [0..$size-1])
#set($value = $index + 4)
#set($minimum = $math.min($nItems,$value))
$segregatedList.add($table.getBooks().subList($index,$minimum)))
$index += 4
#end
I executed the code, while rendering $segregatedList is coming as null.
I verified $table.getBooks() contains the Objects as when I am passing this,Objects are getting rendered successfully.
Can someone please tell what I am doing wrong or how can I create a sublist ?
First you are increment index with 4 and can cause an IndexOutOfBoundsException, so need to change until size-5 (and therefore remove math minimum check)
Second you are adding single Element instead of all Elements using addAll
Third your size check if on wrong parameter - should be on relevant $table.getBooks()
And last make sure your list have more than 5 elements
#set($segregatedList = [])
#set($size = $table.getBooks().size())
#foreach($index in [0..$size-5])
#set($value = $index + 4)
$segregatedList.addAll($table.getBooks().subList($index, $value)))
$index += 4
#end
I'm just learning while doing ramda.js. Well, there are many ways to reach a goal with ramda, but there is on thing I do not understand.
I would like to check the input for an array of strings that all match one regular expression. I thought I could do it R.all(R.both(isString, isRegExp)), but it seems to deliver a true when the input is a number.
As expected R.allPass([isString, isRegExp]) gives a false with a number input.
But can anyone please explain me why R.all is returning a true? Or what and where is mistake (in thinking)?
Complete code:
var isString = R.is(String),
isMyRegExp = R.test(/^[a-z]+$/),
isMyRegExpString = R.both(isString, isMyRegExp),
isArrayOfMyRegExpStrings = R.all(isMyRegExpString),
isArrayOfMyRegExpStringsPass = R.allPass([isString, isMyRegExp]),
result = {
'all': isArrayOfMyRegExpStrings(9),
'allPass': isArrayOfMyRegExpStringsPass(9)
};
console.log(result);
// {
// all: true,
// allPass: false
// }

PS:
I know that I could shorten conditions with just the regexp, but there could be other situations where I need both conditions to be true. eg. isArrayOfNumber and sumOfNumbersOver50.
The second argument to R.all is expecting a list of values to test. Due to the way the function is implemented it is treating the 9 in your example as an empty list, resulting in a vacuous truth and evaluating to true.
