Is there a way to treat the HOST, USER, PASS varibales in the net - ssh gem as an array and have multiple values for them?
I currently have an outside text file with the HOST, USER AND PASS values, but i need to pass these into the aforementioned variables within the net - ssh gem.
Any help and edits to clarify the question are appreciated!
:)
You should be able to do this using the splat operator. Have a read around on this, but Google quickly returns this intro. Using this, you can pass an array of arguments to a method as you describe. Something like:
some_values = ['host_name', 'user_name', 'password']
some_method(*some_values)
If you could update your question to include some example input, what you've tried so far, and the desired result, that'd be really handy to go into greater detail.
I'm not sure if your problem occurs before that, in reading the file / values. If so, show me the file format and I'll have a think - you'll likely need to use something like File.read('your_file.txt').
Otherwise, have a think on storing the values in a YAML file, a common pattern for storing sensitive variables outside of a rail app. With this, you can load the file and access the data as in a hash, and pass across as your arguments.
That help? Hope so - if not, add a little more detail to the question and I'll update to reflect this.

This past year, I took a coding class on creating games using javascript. It is a basic game like Asteroids. When the game ends, it shows the top 5 high scores. The only problem is that when the program is restarted, the array that holds the scores is reset.
I want to store the high scores in a text file or spreadsheet. But, I cannot find a way to get my program to pull information from an outside file and assign it to either a variable, or I would rather put it into an array.
The second part is that when the game ends, it would need to send the updated array to the outside file if it is updated. Everything I look up involves HTML and CSS and we didn't learn this.
Is there any viable way to do this in Javascript?
It seems like the question is 'how do I read and write files from javascript'? The answer largely depends on where you're running the Javascript.
It doesn't sound like you're working in a browser, which makes it likely that you're using Node JS. If this is the case, you'll want to look at the File System API. Specifically, you'll want to create a filehandle by using fsPromises.open(). Once you have this reference to a location on your hard drive, you'll use filehandle.writeFile() to write a string directly to the file, and filehandle.readFile() to read a string directly from the same file.
I am currently building a simple web element editor with React using Redux. It works as it should work with a small number of elements. I can see though that when the number of elements gets on a two digit scale, it will be frustrating to organize and maintain. The reason is because I have to pass [IDs and names (local to the function data), State, Actions] to the function I call which in turn filters the arguments and calls other functions with the right arguments etc. I think it is more ifs than it is needed. Can it be done with a function where I can have all the state and the actions, pass it some arguments, choose the correct path and done?
I do not think that providing code will help with this question, you would have see my file system as well to have the whole picture.
I am a junior developer so please forgive me if this is a stupid question or similar. Thank you in advance!
Could someone point me in the right direction please?
I am trying to extract specific text/numbers from a json payload. I can access/isolate the full string of text by using triggerFormDataValue('text').
The text in question may contain 'sendSMS 1122334455 actual message' as its actual value
Is there anyway, in a logic app flow, to break the text into its component parts?
(sendsms, 1122334455 and actual message)
n.b. I have already tried interacting with the cognitive analysis app for key word searches but that doesn't return the number, nor the full sting, just the key words.
thanks
For more complex logic like the one you have, I would recommend to create an Azure Function. This is a light-weight solution that will offer you the flexibility of a microservice which offers you this possibility.
To extract the numbers, you may use a regular expression.
Edit:
I've found a similar question here on SO, but the conclusion is very similar.
I've done some small research now and it seems Microsoft deliberately does't put too much text parsing functionality in Logic Apps in order to avoid them being too complex. You might have a chance if you put them in JSON notation, but I think the better option would be to go to Azure functions, since it provides reuseability as well.
If that's all you need to do, you can use the split() function. Details: String Functions...split
This is something I have been struggling about for some time now. The thing is: I have many (20 or so) static arrays of values. I say static because that is how I'm actually storing them, as static arrays inside some domains. For example, if I have a list of known websites, I do:
class Website {
...
static websites = ["web1", "web2" ...]
}
But I do this just while developing, because I can easily change the arrays if needed, but what I'm going to do when the application is ready for deployment? In my project it is very probable that, at some point, these arrays of values change. I've been researching on that matter, one can store application properties inside an external .properties file, but it will be impossible to store an array, even futile, because if some array gets an additional value, the application can't recognize it until the name of the new property is added where needed.
Another approach is to store this information in the database, but for some reason it seems like a waste to add 20 or more tables that will have just two rows, an id and a name.
And the last option, as far as I know, would be an XML, but I'm not very experienced with those. It seems groovy has a way of creating and reading XML files relatively easy, but I don't know how difficult would be to modify an XML whose layout is predefined in the application.
Needless to say that storing them in the config.groovy is not an option since any change will require to recompile.
I haven't come across some "standard" (maybe a best practice?) way of dealing with these.
So the questions is: Where to store these arrays?
Use Enum for a fixed set of attributes. Do this, if you rely at some places in your code on some concrete values.
If you do not rely on the attributes within your code (which you obviously don't), use a String-type. In this case, if you need to provide a select box, just do a distinct-query on this property in your database.
Default: Use a domain class per dynamic set of attributes. Another table is OK.
For something as simple as arrays you should use groovy own type of property files. They allow you too define properties as proper groovy variables (not just strings) and obviously loading them would be done dinamically in a simple way by using ConfigSlurper. For an example on how to use this kind of file you can have a look at the following ConfigSlurper:
For defining properties:
my.property.array=[1,2,3,4]
For loading property files:
def config = new ConfigSlurper().parse(new File('myconfig.groovy').toURL())
assert [1,2,3,4] == config.my.property.array
Tip: When you want to access the property files you want to do it in a way that can work for any environment. To make paths environment-independent use the following path as the root path:
import org.codehaus.groovy.grails.commons.ApplicationHolder
def ctx = ApplicationHolder.application.mainContext.servletContext
def rootPath = ctx.contextPath
I'm working on a basic editor application. It uses an array of varying size that I want to store to disk. This will eventually be in an AIR application, but for now it's just an AS3 project in Flex.
I want to store the array in a file. The application edits the data, so it doesn't need to be human readable. I want it to be in whatever format will be quickest to store and load back into the array when I need that data again.
Any recommendations?
Edit: It strikes me that importing/exporting in such a way that it can be immediately cast as an Array() would probably be the cheapest thing rather than some sort of iterating - if that's possible. Another obvious option is getting the data as a simple comma delineated string and using the String.split() function to get an array. Though again, the question is what would be cheapest - and I'm not quite convinced that's it.
I'll also add that it needs to be in some sort of permanent file, so a shared object - while possibly the fastest, isn't really a long term solution.
I think the fastest and easiest way is to use a shared object. It stores native objects, so there is no serialization / deserialization steps involved. Just assign the value and read it back.
Performance wise, probably the fastest route as well. If you are looking for a large dataset and are sure it's an AIR app, you can use AIR's db, but that will definitely take much more work.
First, take a look at this answer.
As for saving the contents of an Array, consider JSON using the export tools provided by Adobe.
