I keep getting this error from this line of code:
result = simplify_path(obj.path_(mlength -2), obj.path_(mlength-1), obj.path(mlength));
result is just a temp variable and the everything has already been defined and works at other places in the code.
simplify_path is a function I defined elsewhere in another file. It is NOT method of my class. I made sure that everything is spelled correctly.
What is going on?
try:
result = simplify_path(obj.path_(mlength -2), ...
obj.path_(mlength-1),...
obj.path_(mlength));

In the course of converting some variables from an API, I need to check if the API is returning a string, such as " N/A", and not a number such as "824". This is the code that I'm attempting to use where, if the variable from the API is a number, leave it alone, otherwise, change it to a = (Zero)
$weather["barometer_min"] = (is_numeric($weewxapi[36]) ? number_format($weewxapi[36],0) : "0");
It does not appear to be working, however, it is not throwing any errors. Can anyone guide me in the right direction?
As shown by Syscall, using 3v4l.org, the code works.

I want this result:
I have a state JSONModel contains the states that I want bind with my UI.
{
code:"None",
descr:"Error"
family:"None"
}
Now, to have my result, I write:
sap.ui.getCore().byId("idCodeInput").setValueState("{state>code}");
sap.ui.getCore().byId("idDescrInput").setValueState("{state>descr}");
sap.ui.getCore().byId("idFamilyInput").setValueState("{state>family}");
and it works fine.
But sap.m.Input doesn't not have valueState property and I can't bind model<-->view from the XML of view. I would like write some like this:
<Input
valueState ="{state>descr}"
value="{model>descr}"
enabled="{enable>descr}"
/>
sap.m.Input has a property valueState

The main aspect of CoffeeScript I'd like to see available also for Dart in form of a different, Dart-based language would be less verbosity, less brackets, less Java-style.
Does such solution exist ?
No.
If you don't want to have your field static you can omit the static keyword.
If you don't want to have your field final you can write var or a concrete type instead of the final keyword.
And if you don't want a loop you can omit for, while, forEach, ...

You can access it Using , month[index]
NSLog(#"%s",month[5]);
It same as You are working with char array in C..

Is there any way that I can list all called methods like there are called one after the other? For example now I am doing same thing in way that I'm putting NSLog(#"MethodName"); i every that method.
I want to do that by automatic way in NSLog. Is it possible?
If you don't have too much methods you can use
NSLog(#"%#" , NSStringFromSelector(_cmd));
to log their names. This way you don't have to copy the signatures manually each time.
Create a property 'NSMutableArray *calledMethods;`
And in each of your method use
[self.calledMethods addObject:NSStringFromSelector(_cmd)];
And whenever you want to print it NSLog it.
I think you want:
printf("%s\n", __PRETTY_FUNCTION__ ) ;
Which produces (for example)
-[AppDelegate application:didFinishLaunchingWithOptions:]
Or, you can use dtrace. This answer should help: https://stackoverflow.com/a/3874726/210171.
