Executing Programs with RF
« on: October 07, 2005, 11:53:10 PM »

Hi all,

I want to create a RetroForth script to do some file conversions for me. The script would use 2 other programs to do the work for me. I was wondering how to do this. The handbook covers using c functions, but not really programs.

Thank you,

Josef

I assume that you want to invoke these other programs from inside RetroForth? If so, it can be done, but I'll need to know what OS you're doing the work on to make sure I use the proper API's when I write an example for you.

Charles,

I am using Windows XP. I am planning on running Lame and TooLame with modifiers each.

Example: lame -a -b 80-e

Thank you,

Josef

Edit: Example: lame --decode <input.mp3> <output.wav> Where ouput.wav could be "-" like in stdout
tooLame -a -b 80 -e <output.wav from lame> <output.mp2>

This isn't too hard; the hardest part will be building the strings initially. Here's a trivial example:

Code:

| This is the import+wrapper that we need to use
| to invoke external programs

from kernel32.dll
2 import WinExec
: run ( addr count -- ) zt 9 WinExec drop ;

| In a definitionL
: notepad s" notepad" run ;

| At the interpreter:
" notepad myfile.txt" run
