Open mod-script-pipe getting freezed in ubuntu

Programming and Development General Audio Programming

I am trying to develop a script with mod-script-pipe utility but when i am trying to open a pipe for writing the commands, its getting stucked. The pipe is present at /tmp/audacity_script_pipe.to.{user_id}. I am using python and audacity appImage(version: 3.7.3). System Info: Ubuntu 22.04.5, also i’ve enabled the mod-script-pipe module from Edit > Preferences > Modules several times. don’t know whats going wrong.

These is the python snippet i am using

import os
import sys


if sys.platform == 'win32':
    print("pipe-test.py, running on windows")
    TONAME = '\\\\.\\pipe\\ToSrvPipe'
    FROMNAME = '\\\\.\\pipe\\FromSrvPipe'
    EOL = '\r\n\0'
else:
    print("pipe-test.py, running on linux or mac")
    TONAME = '/tmp/audacity_script_pipe.to.' + str(os.getuid())
    FROMNAME = '/tmp/audacity_script_pipe.from.' + str(os.getuid())
    EOL = '\n'

print("Write to  \"" + TONAME +"\"")
if not os.path.exists(TONAME):
    print(" ..does not exist.  Ensure Audacity is running with mod-script-pipe.")
    sys.exit()

print("Read from \"" + FROMNAME +"\"")
if not os.path.exists(FROMNAME):
    print(" ..does not exist.  Ensure Audacity is running with mod-script-pipe.")
    sys.exit()

print("-- Both pipes exist.  Good.")

TOFILE = open(TONAME, 'w')
print("-- File to write to has been opened")
FROMFILE = open(FROMNAME, 'rt')
print("-- File to read from has now been opened too\r\n")

its getting stucked on TOFILE = open(TONAME, 'w') and when i press any key its getting exited with KeyBoardInterrupt.

any help would be highly appreciable. Thanks

mod-script-pipe is not properly enabled when running the AppImage version.

A workaround that works for me is to extract the AppImage to squashfs-root, and then run the extracted version.

To extract the AppImage, run the AppImage with the --appimage-extract option.

That worked, thank you very much for the help!
