I need to add vanilla selectors (as #a or #p, but I also want to add there selector arguments as #a[team=blue]) to my plugin command. Is there some library or even some build-in function in bukkit? I tried executing command, that returns UUID or name, but I had problem with reading its result.
I do not really understand what you want, but if you want to return Players UUID just do it like that:
player.getUniqueID();
and thats it. You can return this to a player by making a command and sending him a message with:
player.sendMessage(player.getUniqueID.toString());

I am trying to pass a variable that is string to the ipc query. This does not work for me.
Example:
[`EDD.RDB; "?[`tab;enlist(like;`OrderId;",("string Number),");();(?:;`Actions)]"]
I am trying to query this RDB where OrderId like Number(string)
Number is a parameter but when I passed as string to the remote process, Number is not string any more. I tried to put string in front but still get the same result.
What I want to pass to remote process is this:
Number:"abc"
"?[`tab;enlist(like;`OrderId;"abc");();(?:;`Actions)]"
EDIT as you have updated your question.
It's hard to give a solid answer here as your example is lacking information.
What you have posted is not a valid IPC call in KDB+. I suspect what you may be trying to run is something like:
h(`EDD.RDB; "?[`tab;enlist(like;`OrderId;",("string Number),");();(?:;`Actions)]"])
Assuming Number is an int (e.g. Number:123) then in that case you could rewrite it as:
h(`EDD.RDB;"select distinct Actions from t where orderID like \"",string[Number],"\"")
Which is easier to read and work with. Assuming Number is defined on the client side then the above should return an answer.
If you do want to use functional form then you could try something like:
"?[`tab;enlist (like;`orderID;string[",string[Number],"]);1b;(enlist`Actions)!enlist`Actions]"
As your query string.
If Number is already a string on your process, e.g Number:"123" then you should be able to either:
h(`EDD.RDB;"select distinct Actions from t where orderID like \"",Number,"\"")
OR
h(`EDD.RDB;"?[`tab;enlist (like;`orderID;string[",Number,"]);1b;(enlist`Actions)!enlist`Actions]")
Does the IPC query have to be string? Passing parameters would be cleaner using (func;params) syntax for IPC.
handleToRdb ({[number] ?[`tab;enlist(like;`OrderId;number);();(?:;`Actions)]};"abc")
I am trying to update a string with firebase swift but I am getting an error that I do not know how to get rid of.
I have this code part that is getting an error:
self.dbRef.child("feed-items/\(dataPathen)/likesForPost").updateChildValues("likesForPost": "7")
The error I am getting is expected "," seperator just before the :. I am using dbRef in another code part so I know i works and the dataPathen is being printed just before the above code part, so that is working too.
Can anyone help me with this bug?
Just change
self.dbRef.child("feed-items/\(dataPathen)/likesForPost").updateChildValues("likesForPost": "7")
To
self.dbRef.child("feed-items/\(dataPathen)/likesForPost").updateChildValues(["likesForPost": "7"])
And if you are only looking for incrementing a particular value at a specific node you might wanna check my answer's :- https://stackoverflow.com/a/39465788/6297658, https://stackoverflow.com/a/39471374/6297658
PS Prefer runTransactionBlock: to update properties like likeForPosts as there might be a moment when two users try to like same post at the same moment (Highly Unlikely, but still a possibility...),using updateChildValues might end up just updating like only from one user. But runTransactionBlock: keep firing until the changes of that thread have been committed to the node
updateChildValues accepts [AnyHashable:Any] dictionary:
self.dbRef.child("feed-items/\(dataPathen)/likesForPost")
.updateChildValues(["likesForPost": "7"])
Whenever updating values at any reference in Firebase Database, you need to pass a dictionary parameter for updateChildValues method as [AnyHashable: Any] for your path reference. So just update your code of line as below:
self.dbRef.child("feed-items/(dataPathen)/likesForPost").updateChildValues("likesForPost": "7")
Also if you need to update more than 1 key-value pairs then you can pass those key-value pairs inside dictionary by seperating using comma as below:
self.dbRef.child("feed-items/(dataPathen)/likesForPost").updateChildValues(["likesForPost": "7", "otherKey": "OtherKeyValue"])
I'm using Opa for a school project in which there has to be some synchronization of a textfield between several users. The easy way to solve this, is to transmit the complete field whenever there is a change performed by one of the users. The better way is of course to only transmit the changes.
My idea was to use the caret position in the textfield. As a user types, one can get the last typed character based on the caret position (simply the character before the caret). A DOM element has an easy-to-use field for this called selectionStart. I have this small Javascript for this:
document.getElementById('content').selectionStart
which correctly returns 5 if the caret stands at the fifth character in the field. In Opa, I cannot use selectionStart on either a DOM or a dom_element so I thought I'd write a small plugin. The result is this:
##extern-type dom_element
##register jsGetCaretPosition: dom_element -> int
##args(node)
{
return node.selectionStart;
}
This compiles with the opp-builder without any problem and when I put this small line of code in my Opa script:
#pos = %%caret.jsGetCaretPosition%%(Dom.of_selection(Dom.select_id("content")));
that also compiles without problems. However, when I run the script, it always returns "undefined" and I have no idea what I'm doing wrong. I've looked in the API and Dom.of_selection(Dom.select_id("content")) looked like the correct way to get the corresponding dom_element typed data to give to the plugin. The fact that the plugin returns "undefined" seems to suggest that the selected element does not know the member "selectionStart" eventhough my testcode in Javascript suggest otherwise. Anyone can help?
In Opa dom_element are the results of jQuery selection (i.e. an array of dom nodes). So if I well understood your program you should write something like node[0].selectionStart instead of node.selectionStart.
Moreover you should take care of empty selection and selection which doesn't contains textarea node (without selectionStart property). Perhaps the right code is tmp == undefined ? -1 : tmp = node[0].selectionStart == undefined ? -1 : tmp
Using Watir Webdriver, I wanted to have a helper that would check for any element with given id. I may not know what type it is ( button or link or text). Can I just do
browser.Element(:id, id).exists
All of the examples i've found on google check against a specific element type, as in
browser.button(:id," ").exits
If there is a way, please share the syntax.
In Watir-Webdriver, I would use something like this:
browser.element(class: 'post-tag').exists?
which would find the watir-webdriver tag on this page and report that it exists. Note that I used the 1.9 syntax instead of the alternative syntaxes of:
browser.element(:class => 'post-tag').exists?
or
browser.element(:class, 'post-tag').exists?
As Dave points out, there is #element method. (You were wrong just in capitalization, it is not #Element.)
Since you are asking about accessing it using id attribute, try this:
browser.element(:id => id)
I've never gotten .exists? to work right on it's own.
What I've had to use in these cases has been to explicitly validate the "exist?"... like:
cf_checbox = #browser.text_field(:id=>'continue-ring', :value=>true).exists?
assert( cf_description == true)
without that explicit assertion, I would always get a "true" even when the value didn't exist.
I'm using a plugin and want to perform an action based on the records statuscode value. I've seen online that you can use entity.FormattedValues["statuscode"] to get values from option sets but when try it I get an error saying "The given key was not present in the dictionary".
I know this can happen when the plugin cant find the change for the field you're looking for, but i've already checked that this does exist using entity.Contains("statuscode") and it passes by that fine but still hits this error.
Can anyone help me figure out why its failing?
Thanks
I've not seen the entity.FormattedValues before.
I usually use the entity.Attributes, e.g. entity.Attributes["statuscode"].
MSDN
Edit
Crm wraps many of the values in objects which hold additional information, in this case statuscode uses the OptionSetValue, so to get the value you need to:
((OptionSetValue)entity.Attributes["statuscode"]).Value
This will return a number, as this is the underlying value in Crm.
If you open up the customisation options in Crm, you will usually (some system fields are locked down) be able to see the label and value for each option.
If you need the label, you could either do some hardcoding based on the information in Crm.
Or you could retrieve it from the metadata services as described here.
To avoid your error, you need to check the collection you wish to use (rather than the Attributes collection):
if (entity.FormattedValues.Contains("statuscode")){
var myStatusCode = entity.FormattedValues["statuscode"];
}
However although the SDK fails to confirm this, I suspect that FormattedValues are only ever present for numeric or currency attributes. (Part-speculation on my part though).
entity.FormattedValues work only for string display value.
For example you have an optionset with display names as 1, 2, 3,
The above statement do not recognize these values because those are integers. If You have seen the exact defintion of formatted values in the below link
http://msdn.microsoft.com/en-in/library/microsoft.xrm.sdk.formattedvaluecollection.aspx
you will find this statement is valid for only string display values. If you try to use this statement with Integer values it will throw key not found in dictionary exception.
So try to avoid this statement for retrieving integer display name optionset in your code.
Try this
string Title = (bool)entity.Attributes.Contains("title") ? entity.FormattedValues["title"].ToString() : "";
When you are talking about Option set, you have value and label. What this will give you is the label. '?' will make sure that the null value is never passed.
