reaper.ExecProcess vs .bat

[lollo]

Hi everybody,

I looking for a way to execute this API with a multiline commands.
It's easy do it writing a file *.bat, for example:

REN file1.wav file2.wav
REN file2.wav file3.wav

I found on internet a way to concatenate more line commands. I saw that the solution could be to use the && syntax to separate them, others say you need to use & as separator.
I tried and it doens't works using reaper.ExecProcess API.

Of course my example is very stupid and it haven't sense.
My scope is to have all in a unique line, because my needs is to wait that the first command is finished before to execute the second one, so in my case, I can not use more than one reaper.ExecProcess.

Any suggestion?

Executing an external program is not necessary for renaming files. Lua has a built-in function for that: os.rename.

Yes, I specified well that renaming was not my purpose.
I need use it for rendering and only after it is finished to have the possibility to execute the next one (like a promise)

The problem isn't from ExecProcess, but from your code !


My current BWFscripts just do that (put all different cmds on the a single line).



" & " for windows, "; " for mac.


I think there is other separators to tell "only if success", like " && " for windows, but untested.

Could you post one example for your ExecProcess-call and how you write the bat-file?
