Hello to everybody.

I have this problem.
I need to Exec a command, writing to its standard input, then capturing what it writes to stdout.
I've been bouncing back and forth in the Gambas documentation wiki, without much success.


There is some code here in the wiki https://gambaswiki.org/wiki/lang/open which seems to align with the notion of "read events" I found here and there, which involves the definition of a sub called NAMEOFFILE_Read that is seemingly associated in a magic way to the file with the same name. But it looks like I cannot define a sub inside a sub, so I'm at a loss.

Any help is greatly appreciated.

Capturing what is written in the Console/terminal in Gambas is, in my opinion, one of the most complicated and difficult problems.

Some of my desperate studies in this regard:
   Intercettare i dati inviati allo standard output da un programma C - Gambas-it.org - Wikipedia
   Intercettare il risultato restituito ad intervalli temporali di un comando bash - Gambas-it.org - Wikipedia
   Intercettare la stringa di caratteri immessi dall'utente nella console o Terminale - Gambas-it.org - Wikipedia
   Intercettare quanto viene scritto manualmente nella console o in un Terminale - Gambas-it.org - Wikipedia

LOL hai ragione, in realtà sono bergamasco, di solito uso nomi sensati per le variabili ma per l'appunto ero arrivato all'ostrega

Well, congrats for your research!
By the way I understood what I previously referred to as "magical", that is Event names.

In the end I think I'll end up to use something to the likes of


or, which I thinks should be better in the long run, I'll use temporary files in /dev/shm to pass data around.

It still baffles me that such a trivial task is so overly convoluted

Thanks very much

For passing data from one program to another, you can also see these pages:

Here is a simple method to use piping with your program..
