Sorry if this is a newbie type Q but after much searching I cannot find the answer. I am trying to understand how to write a process (function?) that I can call from any flow in Node Red. Every time I search "global function" the (web / blog) results want to teach me how to write a simple function in a flow. I've got that in spades. I'm sure the answer is simple, just finding it doesn't appear to be. Closest I got is writing it in settings.js but no clear examples to give me confidence.
As one simple example, I use a timestamp that is in easy human readable form (12 hr am/pm) for logging. Currently I have to write a time stamp procedure (new Date) in each flow before writing it to the log file. I'd like a one-liner in each flow that calling a global function I write that every flow can access. TIA

I may be new to tradingview but their pinescript programming language seems to be the best I've ever seen for automated trading. They seem to really want me to succeed but I cannot find where it tells me how to access the balances for certain balances. I am trying to make a code where I do not reinvest the extra I make so I have to be able to reference the available amount. I have not quite finished the manual yet but I do not see what variable or function allows me to do that, or at least not where I would expect it.
Have a look at strategy.equity. There are quite a few built-in variables for strategy values. You can inspect them from the refman by searching on "strategy".
You can also calculate your own metrics using a technique like this one if you don't find what you need in the built-ins.
And welcome to Pine! This is the best place to start your journey:

Metaphorically speaking, I'm learning python in a community college for game programming; and our second assignment is to make a text based game. I'm stuck trying to figure out how to get the code to run if the player has something in their inventory, then display these options or print these options if they don't have that certain item in their inventory.
What you describe is what was a very popular type of game a long time ago. The most difficult portion of this type of game is interpreting user input. You can start with a list of possible commands, iterating through each token of the user's input. If I type
look left
the game can begin by calling a method or function which interprets the available visual data. You will want to look into your database implementation for what is left in relation to the current player's position. The game can respond with
You see a wooden box on the floor. It is locked.
You get the idea. As the user, I will probably want to check my inventory for a key. You can implement a subroutine in your parser for searching, categorizing, and using your inventory. The key to writing anything like the described program is spending at least twice as much time testing and debugging the game over how much time you spent coding the first working version. The second key is to make sure you are thinking ahead. Example: "How can I modularize the navigation subroutine so that maps can be modified or expanded easily?"
Comment if you have any questions. Good luck coding!
I have a requirement to add fields onto a form based on data from another set of entities. Is this possible using an event script or does it require a plugin?
Given that I understand your assignment correctly, it can be done using JavaScript as well as a plugin. There is a significant difference that you need to take into consideration.
Is the change to the other entities to be made only when an actual user loads a form? If so, JS is the right way.
Or perhaps you need to ensure that those values are written even if a console client or system process retrieves the value of the primary entity? In that case, C# is your only option.
EDIT:
Simply accessing the values from any entity in the onload event can be done using a call to oData. I believe someone else asked a similar question recently. The basic format will look like this.
http://Server:Port/Organization
/XrmServices/2011/OrganizationData.svc
/TheEntityLogicalNameOfYoursSet()?$filter=FieldName eq 'ValueOfIt'
Some extra remarks.
If you're targeting on-line installation, the syntax will differ, of course, because the Schema-Server-Port-Organization are provided in a different pattern (https, orgName.crm4.something.something.com etc.). You can look it up on Settings.
Perhaps it should go without saying and I'm sure you realize it but for completeness' sake, TheEntityLogicalNameOfYours needs to be substituted for the actual name (unless that is your actual name, in which case I'll be worried, haha).
If you're new to this whole oData thingy, keep asking. I got the impression that the info I'm giving you is appreciated but not really producing "aha!" experience for you. You might want to ask separate questions, though. Some examples right off the top of my head.
a. "How do I perform oData call in JavaScript?"
b. "How do I access the fetched data?"
c. "How do I add/remove/hide a field programmatically on a form?"
d. "How do I combine data from...?"
I am relatively new to Node.js and I am trying to get more familiar with it by writing a simple module. The module's purpose is take an id, scrape a website and return an array of dictionaries with the data.
The data on the website is scattered across pages whereas every page is accessed by a different index number in the URI. I've defined a function that takes the id and page_number, scrapes the website via http.request() for this page_number and on end event the data is passed to another function that applies some RegEx to get the data in a structured way.
In order for the module to have complete functionality, all the available page_nums of the website should be scraped.
Is it ok by Node.js style/philosophy to create a standard for() loop to call the scraping function for every page, aggregate the results of every return and then return them all in once from the exported function?
EDIT
I figured out a solution based on help from #node.js on freenode. You can find the working code at http://github.com/attheodo/katina_node
Thank you all for the comments.
The common method, if you don't want to bother with one of the libraries mentioned by #ControlAltDel, is to to set a counter equal to the number of pages. As each page is processed (ansynchronously so you don't know in what order, nor do you care), you decrement the counter. When the counter is zero, you know you've processed all pages and can move on to the next part of the process.
The problem you will probably encounter is recombining all of the aggregated results. There are several libraries out there that can help, including Async and Step. Or you can use a promises library like Fibers.Promise. But the latter is not really node philosophy and requires direct code changes / additions to the node executable.
With the helpful comments from #node.js on Freenode I managed to find a solution by sequentially calling the scraping function and attaching callbacks, as Node.js philosophy requires.
You can find the code here: https://github.com/attheodo/katina_node/blob/master/lib/katina.js
The code block of interest lies between lines 87 and 114.
Thank you all
Is there any way to generate automatically the result of an SAP transaction? Let's say I want to see the production orders for one MRP controller (I have the COOIS transaction for this). Is there any way to generate an XML feed with the result of that transaction and refresh it let's say.. every 10 minutes?
Or to auto-export an .xls file with the result somewhere... ? I know I have the jobs and the spools but I have to manually download the result from the SAP GUI.
I don't have access to ABAP so I would like to know if there are other methods to get data from SAP?
Since "a transaction" might be anything from a simple report to a complex interactive application that does not even have a simple "result", I doubt that there's a way to provide any generic tool for this. You might try the following:
Schedule a job and have the result sent to some mailbox instead of printing it. Then use the programming language of your choice to grab and process the mail.
Check whether there are BAPIs available (BAPI_PRODORD_* or something like that - I'm not a CO expert, so I wouldn't know which one to use). You can call these BAPIs from an external program without having to write ABAP yourself - however, you'll most likely need the help of someone who knows ABAP in order to get the interface documentation and understand the concepts.
