How can first program ABC.ring call second program DEF.ring

[Bert Mariani]

Hello Mahmoud

I have a problem with this issue ...

1st program Create2DList.ring  generates a 2dList 

Calls 2nd program  ChartPrint2DList.ring  which will Print the 2DList and later Draw a Chart

I need to call the 2nd program Program  and not the internal Functions

         ChartPrint2DList.ring (a2DList) 

How do you do it ?

How do I call it ?

Programs are attached.

if I define

   load "ChartPrint2DList.ring"    //  Call FUNC

   Print2DList(a2DTest)               // Calls Func  IN  "Chart-Print2DList.ring"

 //  load "ChartPrint2DList.ring"   // Comment Out

if I call  the program  ChartPrint2DList.ring (a2DList)  // FAILS

It only shows 2 sysArgs and not the 3rd for the 2DList

     sysArgV: 1 ring.exe
     sysArgV: 2 ChartPrint2DList.ring

/===============================================

load "ChartPrint2DList.ring"   // <<< Will call Func , But Not program

    See nl+"IN Create2DList.ring "+nl
    a2DTest = List(3,4)
    for Row = 1 to 3
        for Col = 1 to 4
            a2DTest[Row][Col] = Row *Col
        next
    next
   
    DebugArray(a2DTest)       // Before calling Pring2DList

See nl+"CALL: Print2DList.ring(a2DTest) "+nl  
        Print2DList(a2DTest)    // Calls Func  IN  "Chart-Print2DList.ring"

See nl+"CALL: ChartPrint2DList.ring(a2DTest) "+nl
ChartPrint2DList.ring(a2DTest)   // COMPLAINS

===================================

GOOD

CALL: Print2DList.ring(a2DTest)

Now IN Print2DList : Where is sysArgV a2DTest ?

Hello Bert,

we talked about this long time ago. Separate processes use separate memory. Ring doesn't support shared memory between the processes.

You need inter-process communication which you can implement using files (pipes) or sockets, command line arguments (only at the start of the process) or Qt

https://doc.qt.io/qt-6/ipc.html

Greetings,

[Mahmoud Fayed]

Hello Bert, Ilir

We have the next useful functions

(1) isMainSourceFile() from stdlibcore.ring:  Stdlib Functions — Ring 1.24.0 documentation

(2) appArguments() from stdlibcore.ring: Stdlib Functions — Ring 1.24.0 documentation

(3) isGlobal():  Reflection and Meta-programming — Ring 1.24.0 documentation

 

Using these three functions we can control the behaviour of our source code file 

* Determine code to be executed if our program is the main program (used like ring myprogram.ring)

* Determine code to be executed if our program is the sub program (used like load "myprogram.ring")

* Get application arguments (sysargv) taking in mind if the program could be executed using (ring.exe) or as standalone executable (myprogram.exe)

* Check if a global program does exist (could be used by the caller program to send parameters)

Greetings,

Mahmoud

Hello Mahmoud

If 1st Program Writes  to  OutputData.txt file and closes the file.

How can it Call the 2nd Program, which will Read the OutputData.txt  and process it ?

[Mahmoud Fayed]

Hello Bert

>> "How can it Call the 2nd Program, which will Read the OutputData.txt  and process it ?"

Many options

If the first program writes the code directly, in global scope, just use the Load command after creating OutputData.txt

But, A better way, is to call a function in the second program and keep load command at the start

And control code executed in the second program using isMainSourceFile() - To determine code that will be executed only if the second program is the main program.

Mahmoud

[Mahmoud Fayed]

Hello Bert

As Ilir said, using  system( "ChartPrint2DList.ring(a2DTest)" ) is not the right way to pass a Ring list to another program

If you want a simple way to pass a list, write this list to a file, then read this file from the called program

You can use the next functions

(1) List2Code() from stdlibcore.ring:  Stdlib Functions — Ring 1.24.0 documentation

(2) Read() function:  Files — Ring 1.24.0 documentation

Greetings,

Mahmoud

[Mahmoud Fayed]

Hello Bert

If you will use List2Code() and Read()

Then you will need Eval() after using Read()
Also, it's expected to use variable assignment, so the list is stored inside a variable

Greetings,

Mahmoud 

[Mahmoud Fayed]

Hello Bert

>> "If you want a simple way to pass a list, write this list to a file, then read this file from the called program"

This statement assumes that the programs will be executed as different executable files 

So, we need a way of communication (IPC, Files, Sockets, Database, etc.)

But if you don't have this case, i.e. just two source code files written in Ring and you have full control to write/organize them

Then there is no need for this complexiity

Just use a global variable (for the list that you want to share) then use isGlobal() in the sub program to check/use it

Or just pass the list as parameter to a function in the sub program (Simple & Better)

Greetings,

Mahmoud

[Bert Mariani]

Hello Mahmoud, Illir

All this does not make sense. Seems convoluted

Line 43 Error (R5) : Can't access the list item, Object is not list
In function debug2darray() in file C:\MyStuff\AA-Curl-DISTRIB-Ring124\ChartPrint2DList-2.ring

it should be simple logical steps

      First program Writes  the 2DList  as a file  "AAA-Output.txt"   ( codeString = list2Code(a2DTest)

      Calls Second program  ( No Call Command  exists )

      Second program reads the file   " AAA-Output.txt"  ( Looks like 2DList)

                   Fails - Does not recognize data as a 2DList ??

When using  load in First program ...  

     load "ChartPrint2DList-2.ring"  // ===>>> CALLS the Second program First ???  Why

So I put the "load" at the END of the First program !

Which now calls the Second program

Why is there not a Call Command for the Second program

Why is an EVAL() command required after the Read()

EVAL what ??

The Read Data looks visually fine.

Hello Bert

An example using List2Code() and Eval()

load "stdlibcore.ring"

aList = [ [1,2,3],
  [4,5,6] ]

cListAsString = list2code(aList)
?   cListAsString    

cCode = "aAnotherList = " +   cListAsString    
eval(cCode)

? aAnotherList

Output:

[
        [
                1,
                2,
                3
        ],
        [
                4,
                5,
                6
        ]
]

Comments:

(1) Using List2Code() generate a String that contains Ring code that represent the List Contents

(2) Adding  "aAnotherList = " before this list determine the variable name that will contains this list

(3) Using Eval() execute the code (stored inside a string) and create the variable (which contains the list), So Ring code can use this list

(4) You can use write() and read() functions to save cListAsString to txt/data/ring files 

if you have all files in one program (one executable), A better way is using isMainSourceFile(), defining a function that accept the list, i.e. no need for List2Code(), eval(), etc.

Hello Bert, Mahmoud

load "ChartPrint2DList-2.ring"        // ===>>> CALLS the program
System("ChartPrint2DList-2.ring")

Since load "ChartPrint2DList-2.ring" is used, question is why you are calling another program when you already loaded the code printing the list? Load doesn't calls the program, load generates the bytecode so that list printing function can be called.

That's what is Mahmoud trying to tell you.

Hello Mahmoud, Ilir

(Removed the "System" cmd)

Updated both First Initial program - Create2DList-2.ring

and the Second Called program- ChartPrint2DList.2.ring

Looks like it works

But the Output File to read by the Second Called program is hardcoded.

Question: 

I have this code at the End of the First program -- Create2DList-2.ring

How do I pass it the Name of the Output file --  cFileName = "AAA-Output.txt"  to  ChartPrint2DList-2.ring

             See nl+"Third CALL: for LOAD ChartPrint2DList-2.ring "+nl

load "ChartPrint2DList-2.ring"        // ===>>> CALLS the program

Doing a --  load "ChartPrint2DList-2.ring"   -- doesn't make any sense to me. Can't pass Parms

Ring should have a  -- CallProg( ProgName, Parm1, Parm2 ...)

Hello Bert,

since you Removed the "System" cmd, you don't need anymore inter-process communication. Remove sections which write/read file content.

All what you need to do now is to use Debug2DArray(a2DTest) in ChartPrint2DList-2.ring because a2DTest is now global variable created in Create2DList-2.ring.

Ilir

Hello Bert, Mahmoud, Walir, and everyone 

I've been following the conversation, but I don't understand what you're trying to achieve. 

Could you please describe in clear terms what you want to do so we can understand how to help? 

I don't need examples

please specify what you want first.

 Regards, Azzeddine

[Azzeddine Remmal]

Hello Bert, 

You are correct that load in Ring acts more like a copy-paste or #include mechanism rather than a function call.

It executes the code in the current scope immediately.

Here are the two ways to handle this:

Option 1: Shared Scope (Easiest)
Since load shares the variable scope, you simply define the variable before the load command.

In Create2DList-2.ring:

// Define the variable first
cFileName = "AAA-Output.txt"

see nl+"Third CALL: for LOAD ChartPrint2DList-2.ring "+nl
load "ChartPrint2DList-2.ring"  // This file can now "see" cFileName
In
ChartPrint2DList-2.ring
: You can just use cFileName directly. (You correctly commented out the hardcoded assignment in your recent edit).

Option 2: Wrap in a Function (Cleaner)
If you want a syntax like CallProg(Name), you must wrap the code in the second file into a function.

1. Modify
ChartPrint2DList-2.ring
: Wrap the logic inside a function definition.

func ChartPrint2DList(cOutputName)
    see "Processing file: " + cOutputName + nl
    // ... rest of your code using cOutputName ...
2. Modify Create2DList-2.ring: Load the file once to define the function, then call it.

load "ChartPrint2DList-2.ring"

// Now you can pass parameters
ChartPrint2DList("AAA-Output.txt")

Hello Azzeddine

Thanks for the feedback and suggestions !!

I was looking at the AI generated code.

Looks like Claude AI , am I right ?

I was not aware of the QTChart abilities QtQuick 2.0  QtCharts 2.0

I was doing my own charts drawing.

So this is a nice  feature to know.  

For some reason after running the code, I see only 1 chart not 2  charts ??

It is using:

system("ring Curl-Get-HIS-NASD-100.ring")

Can I pass parameters to tell it  things like

     Filename         ( to save as, or read from)

     quotes.ini        (file that has all 100 stocks to use)

     Interval  1mo   (fetch 1 month intervals og data )

     Range    5y       ( fetch 5 years worth of data  =>  60 months)

    cUrl = "https://query1.finance.yahoo.com/v8/finance/chart/" + cSymbol + "?interval=1mo&range=5y" 

The AI code has a BUG when the stock has 42 or 50 months of data and not the full 60 months

It doesn't realign (shift to right)  the data so that the most current month is on the right,

For my performance calculations for good results on the 100 stocks

Compare  this month price to  price 7 months ago

Buy the Top 7 stocks => TOT  

Compare to QQQ 

Can you ask the AI to the calc and compare using  the above ?

Hello Bert, 

I was looking at the AI generated code.

Looks like Claude AI , am I right ?

I only write the code by hand when I'm offline. 

As for the llms (Gemini), it's not important because I deal with them professionally

I don't send requests like that. I use contextual engineering with them.

See the attached application.

Hello 

Now we have a package for the Stock Analysis application by our friend Azzeddine

* Install

ringpm install stockanalysis from ringpackages

* Run

ringpm run stockanalysis

Greetings,

Mahmoud

[Mahmoud Fayed]

Hello Bert, Azzeddine

The StockAnalysis application is updated to use QProcess, remove() and avoid System() function

This provides too much better performance

Updated in this commit:  Update applications/stockanalysis/backend.ring - Use QProcess and avo… · ring-lang/ring@0f3da72

Also, the StockAnalysis package is updated to include these changes 

Greetings,

Mahmoud

[Mansour Ayouni]

Hello Mahmoud,

I also use system() calls to run external tools in Softanza (Graphiz Dot.exe, Python.exe, etc).

Is QProcess() better for this case?

Best,

Mansour

Hello Mansour

>> "Is QProcess() better for this case?"

Yes, it's faster and avoid showing the terminal/command prompt window when executing commands from GUI apps

Also, QProcess is part of QtCore (Doesn't requires the other Qt modules)

So, it can be used after load "qtcore.ring" i.e. it's not necessary to use load "guilib.ring"

Mahmoud

Thank you very much Mahmoud!

Hello Azzeddine

I get different Performance results compared to your program.

    Run  

    -  Curl-Get-HIS-NASD-100.ring   which calls  

    -   YearlyReturns.ring   which calculates ad draws the chart

I get  QQQ: 1.67  vs  TOT: 4.05

See attached CSV files.

     - AAA-CompareResult.csv

     - AAA-CompareResult-Bert.csv

I generate the performance for every Stock based on  

      -  Change of price for  (current  Month)   /   (Month-7 )  for each and every month

      -  Sort by Top 7 results for each and every month

      -  Average out the Result / 7   => TOT for that month

      -  See spreadsheet

==========================

These are the routines

        ReadCSVFile()       // aList = csvfile
        CreateLists()       // tList with Symbol
        CalcPerformance()   // pList
        SortPerformance()   // sList => nList Name
        GenerateRank()      // rList
        BuyRank()           // bList = Price in nCol if Rank <= Top10
        CalcGain()          // gList = Gain = Buy at nCol See at nCol +1
        MonthlyGain()       // mList = Avg Gain for each nCol
        Compounding()       // cList = Compoud gains by Periods
        SummaryStock()      // Stock Compunded
        SummaryTotal()      // Total Top10 Compounded vs QQQ
        ShowTop10()         // Show last top10 Symbols

Performance Charts

[Azzeddine Remmal]

Hello Bert

Please don't send me back to the stock market and forex. 

I've tried everything: classical analysis, indicators, even Japanese candlesticks in my dreams.

Do you know that I discovered Ring while desperately trying to program an expert for the stock market and forex? Then one day in 2017, I asked Mahmoud for his opinion, and he advised me: "Providing added value to society is better than a program that buys and sells money." I abandoned it after that. Anyway, the program is right there in front of you modify it as you see fit. 

Regards, Azzeddine

[Bert Mariani]

Hello Azzeddine

Thanks for sharing your story.  :D

I had written a Stock program in  C++ back in 1991. and kept it  current ever since.

Based on my theory of buying the best performing stocks as per my algorithm.

When I came across Ring ...

I wanted to see it could do two things easily.

   - Can it Download Data from the Internet - Prices and Dividends

   - Can it Draw a Chart of those Stock Prices and Dividends

Answer

    - Yes it can - Easily !!

    - Since then I have written Ring programs  on a variety of topics of interest.

I still use and prefer my C++ program

For Speed and Data Structures.

Yes. I can modify your code.

But I figured that you can do it quicker  :D
