val time = json.lookup<String?>("query.results.channel.title").toJsonString(true)
outputs
["Yahoo! Weather - Nome,AK,US"]
is there a way to get the output without the brackets and the quotation marks ?
I guess that
.replace("[\"","").replace("\"]","")
isn't the best way
The brackets are contained in the default implementation (see https://github.com/cbeust/klaxon/blob/master/src/main/kotlin/com/beust/klaxon/DSL.kt at the very bottom function appendJsonStringImpl)
So it is not possible, to remove them by configuration.
It might work if you write an extension function for this particular class, but i guess this is not what you want.
So this is currently not possible without writing your own extension(-function).

I am using the Chrome plugin JsonDiscovery that use JORA to Query in JSON and make JSON query. But know when I consult the MS DevOps API that return the fields with dots in the name I coldnt make the query because JORA understand the dot like to get the next field in the hierarchic.
{
Microsoft.VSTS.Common.ValueArea: "Business",
Microsoft.VSTS.Scheduling.Effort: 40,
Microsoft.VSTS.Scheduling.StartDate: "2021-01-11T03:00:00Z",
}
Dows Someone know how I can make the query with those dots in the name ?
When a property has forbidden chars for an identifier, you should use the same approach as in JavaScript, i.e. $['Microsoft.VSTS.Common.ValueArea'].
For Jora foo['bar'] is the same as foo.bar. However, in first case you can use any chars for a property name, but the second one is faster to type and easier to read.
After many times debugging the Jora, I found the pick method.
..pick("Microsoft.VSTS.Common.ValueArea")
I'm trying to fetch results via API using the module askargs. I have no problems getting results when I have just one condition or more conditions aggregated with the operator AND where I make use of the pipe character to separate them (like written in documentation).
E.g.
[[Category:+]] AND [[Jurisdiction::A]] AND [[Type::B]]
Category:+ | Jurisdiction::A | Type::B
But the pipe character doesn't work with OR.
I need to be able to use both logical conditions with several arguments within the same query.
Am I missing something?
Am I missing something?
No. The API doesn't handle OR condition, due to simplistic code in the query parameters formatter.
See file SemanticMediaWiki/src/MediaWiki/Api/ApiRequestParameterFormatter.php
at line 132:
protected function formatConditions( $condition ) {
return "[[$condition]]";
}
Every condition in the query is formatted with surrounding brackets, leading OR to be interpreted as a page title.
An alternative is to use Special:Ask with URL encoded query and json format:
https://www.semantic-mediawiki.org/wiki/Special:Ask/-5B-5BHas-20keyword::askargs-5D-5DOR-5B-5BHas-20keyword::ask-5D-5D/-3F%3Dhelp-20page/-3FHas-20description%3Ddescription/format%3Djson
Since I came here from a website search i'm going to add another neat possibility:
If you use the Alternative separator you can use a double pipe as logical OR conjunction.
Example:
%1FCategory:+%1FJurisdiction::A%1FType::B||C
Which should be read as following
Category:+ AND Jurisdiction::A AND (Type::B OR Type::C)
How can I restrict the input of a TextFieldsuch that it can only contain mathematical expressions?
Accepted inputs would be:
"3+5"
"-5 + 6"
"3/2(6*4)"
"6--5"
"+5-3"
etc..
And rejected inputs would be:
"5+++3"
"6(7)"
"6-6-+-7"
and so on.
Basically; the syntax I want it to be restricted to is the kind of syntax that programming languages normally use for evaluating mathematical expressions, kinda like the syntax input you'd expect from your everyday calculator.
I'm making a program in which I want the user to be able to input numbers and/or calculations into a text box, instead of having to use a calculator to do it and then arduously type out a number with 7 decimal places.
I've done a little look around and I've seen a lot of stuff involving Regex, postfix, BNF, and the like. A lot of it looked very complicated, too complex for my understanding, and none of it had anything to do with AS3.
However, I've had a thought about making this problem a whole lot simpler by just converting the string into a mathematical expression that AS3 can understand, and let Flash handle the errors using try catch, but I don't know how to do that either (Number("3+5")resulted to NaN).
I'm currently restricting text input to just numbers using Event.CHANGE, like this:
function Restrict(event:Event):void
{
if (event.currentTarget.text.indexOf(".") == -1)
{
event.currentTarget.restrict = "0-9.";
}
else
{
event.currentTarget.restrict = "0-9";
}
}
and it's seemed to work well so far.
I intend to implement this new restriction in this manner, but if there is a much more efficient way of restricting text input, please feel free to include it in a response.
Just to reiterate for clarity, I am asking how to implement functionality that will enable someone to input a mathematical expression into a TextField, and the program will register that input as an expression and calculate it.
Thanks for reading.
EDIT: I've done a bit more research and I've stumbled upon a Reverse Polish Notation calculator/parser/utility class/library/thingy that looks very useful. Seems kinda similar to the Executer class that fsbmain mentioned, but it looks a lot simpler to use and easier for me to understand.
However the problem still remains that I'd have to find an efficient way to restrict the syntax of user input to mathematical expressions, but at least now I have at least two ways of converting the string into a number for calculations.
That's quite a tough question actually, even definition for valid mathematical expressions which you mentioned is very complicated itself, i.e. expression 6-6-+-7 is a valid from as3 syntax point of view and gives result 7.
Regarding second part of your question:
converting the string into a mathematical expression that AS3 can understand
That's not possible to do with only native as3 means since eval-like functions are gone since as2 time, but you can try to use some as3-written syntax translator, i.e. Executer from flash-console project:
var exec:Executer = new Executer();
var res:* = exec.exec(this, "6-7");
trace("exec = " + res); //output "-1"
Although it's failed with some complex expressions from your question:
var exec:Executer = new Executer();
var res:* = exec.exec(this, "6-6-+-7");
trace("exec = " + res); //output "- 7"
I've a function which is called from different components, .cfms or remotely. It returns the results of a query.
Sometimes the response from this function is manually inspected - a person may want to see the ID of a specific record so they can use it elsewhere.
The provided return formats, being wddx, json, plain all aren't very easily readable for a layman.
I'd love to be able to create a new return format: dump, where the result first writeDumped and then returned to the caller.
I know there'd be more complicated ways of solving this, like writing a function dump, and calling that like a proxy by providing the component, function and parameters so it can call that function and return the results.
However I don't think it's worth going that far. I figured it'd be great if I could just write a new return format, because that's just... intuitive and nice, and I may also be able to use that technique to solve different problems or improve various workflows.
Is there a way to create custom function returnFormats in ColdFusion 10 or 11?
(From comments)
AFAIK, you cannot add a custom returntype to a cffunction, but take a look at OnCFCRequest. Might be able to use it to build something more generic that responds differently whenever a custom URL parameter is passed, ie url.returnformat=yourType. Same net effect as dumping and/or manipulating the result manually, just a little more automated.
From the comments, the return type of the function is query. That being the case, there is simply no need for a custom return format. If you want to dump the query results, do so.
queryVar = objectName.nameOfFunction(arguments);
writeDump (queryVar);
How can I have a clean html ouput for search result pages? Each time I try to include special characters like "&" as part of the search term, I usually get results with "&" highlighted yet includes the HTML entity. Thus, the results has &, " etc...Here's a screenshot sample - http://min.us/mt3rOV5zVtOh6
Meanwhile, when I do my searches with "&" included in the search term, the result yields to having a clean output.

I've already tried several decoding functions but no success. Been trying to fix this for days already. The site is using Drupal 6 and the search module has been overridden.
You say "...the search module has been overridden" this could be the cause of why the search snippet remains htmlentityencoded on output ( e.g check_plain'd escaped html )
A better fix would be to find the cause in the modification, e.g a preprocess function that modifies the search snippet ( if any )
Alternatively, you could probably run the $snippet through decode_entities
i.e print decode_entities($snippet)
Assuming, the html is already escaped, as if not, can be a security risk.
See also: http://php.net/manual/en/function.html-entity-decode.php
and: http://www.php.net/manual/en/function.htmlspecialchars-decode.php
Well, you could try drupal_html_to_text to convert the snippet into plain text.
The right way is probably to figure out why those results aren't getting converted. Based on your comments it looks like the problem is only when you search specifically for "&". More specifically, it's the regex in the search.module (/modules/search/search.module - line 1188 in 6):
preg_match_all('/ ("([^"]+)"|(?!OR)([^" ]+))/', ' '. $keys, $matches);
It only matches spaces before the keyword (not after). You could modify the $keys here like:
if ($keys == '&') $keys = '&'
Or something like that (of course that means hacking core - meh).
You could also possibly add a form_alter via a module and modify the search form (see this link on how to add the form_alter). Then you could add a custom submit handler which would alter the search term in the form before it is submitted.
