Re: Python to LiveCode
I have converted from language to language and what I did initially was to comment what every section of code did and how it did it (algorithms and logic). The idea was that I should be able to delete the initial code and reproduce it using the comments. Then take the comments and write the code in the destination language. Yes you might organize it differently but my goal was to get it completely functional so that it could pass the existing unit tests on the original source. Once the code is functional, I refactored it to make it more in line with the way the destination code is typically structured. That’s what I did. Tedious but straightforward and successful.

I was reading about open process:
--open process appName [for [text|binary] {read | write | update |
neither}]
I can open a process and execute the above mentioned external program
but I am not able to supply the arguments.
Is it possible using open process to execute a program with arguments
and if it is would it be better to use the shell command or open process?
I know if you use a shell command it takes control until it is done and
open process might run in the background which I do not really need
that I know of in this instance.

I would like to take the python code and convert it to LiveCode. I know there is a cheat sheet but it is limited. 1. Has anybody attempted this and what worked and didn't work? 2. Can someone point out the problems moving from one programming language to LiveCode? Everyone on the list has been great and thank all of you.

Re: open process
passing information (arguments, commands, etc.) to another program using
"open process" requires that the other program has a mechanism to listen
to interprocess messages. Most programs designed to accept a set of
command-line parameters do not have listeners for inter process
communication (IPC), so the general answer to your question is you
probably can not provide arguments via open process to the copy command.
