kandi X-RAY | beethoven Summary
Beethoven runs in your cluster as a container managed by Marathon or Docker Swarm Mode. This allows for horizontal scaling across the cluster. Supervisor is leveraged to manage both Nginx and Beethoven since we are running two executables in a single container. Beethoven attaches to the event stream and listens for real-time changes to Services and Tasks. This includes new applications being added to the cluster or existing which has had a state change such as a health event. When an event occurs Beethoven takes the user provided nginx.template and parses it with the Handlebars processor. Handlebars offers a lot of power behind the template including logic blocks, object iteration and other conditional behaviours. After the template has been parsed a temp Nginx configuration file is rendered within the container. Beethoven then asks Nginx to validate the temporary configuration file to determine if it's syntax is correct. If the syntax is good then the current nginx.conf is replaced with the temp. file and a soft reload is issued. If the temp file is bad then it is recorded and associated with the /bt/status/ endpoint for debugging.

QUESTION
I've looked through many questions here, but the syntax is unfamiliar to me. I am trying to write a program in C, that given a composer's name, will give you the instrumentation that composer used in orchestral music. I am trying to figure out how to format strings in an array, but the compiler won't recognize them. I have tried using one variable, no luck. Right now, only errors from compiler are "undeclared identifiers" for each indexed composer's name in j[0], j[1], j[2]. So far I have:
...ANSWER
Answered 2020-Dec-30 at 18:30You are referring to the names as identifiers and not as constants like you want them to be. Change Wagner to "Wagner" for example. You get an error because these identifiers were never defined before being used by you.
Also, right now when you are comparing the strings you are comparing their addresses in memory. Consider using strcmp if you want to compare the strings and not their addresses.

Answered 2020-Aug-16 at 17:33usort gets passed the elements from the array exactly as they are. i.e. in this case your array contains objects - therefore you need to do the comparison on the properties of the objects and not as elements in an array.
Instead of comparing the items as array elements like this:

Answered 2020-Jul-11 at 16:42I only have time for a quick answer at the moment, but maybe this will help.
The default handlers for a listbox aren't going to do what you want, they just change the appearance of the item that you click on. But you can establish any desired handling for a button click using the bind function.
The tk bind function is used to specify what should happen when an event occurs in the user interface. What you want to do is to specify something that happens when button 1 (say) is clicked in the listbox. I don't have labltk installed on my system, so I can't try out this code, but it would be something roughly like this:

I have the following code and need to add two extra things to it but I'm stuck and not sure how to do it.
I need to add:
If there are no products in the category a NotFound component will show a message.
By typing 'all' in the input we should be able to see the entire list of products again from all the categories.
Ideally I'm looking for the simplest solution as I'm currently learning React. Thanks!

...ANSWER
Answered 2020-Jul-01 at 10:04There are a few things which confused me much when analysing your code, so will share them with you, as if in the future you work on teams, it would be handy if other people can understand your code.
You have an on change event for the text box which is different to the event for the search button next to it. Users would expect it to be the same and so that's really confusing.
You have 2 lists of items essentially, a raw and unfiltered and you switch between which 2 to present on the screen. Sometimes you need to have a raw set and that's fine, but perhaps make sure that the only ones which are
presented as suchis just either thestate.itemsor thestate.filtered. I would probably expect thestate.filteredMake your search case insensitive, e.g. pop should match Pop
If there are no products in the category a NotFound component will show a message.
For this I would first modify your show logic to work on the same filtered list just change your event functions to manipulate the filtered list and untouch the items one.
add another condition perhaps for when there are no cases

The {{#if}} blocks are optional. I prefer these so if an application is removed all together in the cluster then the final nginx.conf is valid
The /_health endpoint at the bottom is optional. If allows for Marathon health checks to use that to determine Nginx is running.
The /_bt endpoint at the bottom is optional. If you would like to find information such as updated times and any failures from Beethoven then this mapping allows you to expose these internal endpoints via Nginx. Alternatively you can expose Beethoven via it's configured port.
