Convert Label text to LRC file

[bigboss97]

I modified the code and write the output to a binary file:

Code: Select all

 write_json = open('labels.json', 'wb')
*snip*

   while (last != b'\n' or line != b'\n'):
        last = line
        line = read_pipe.read(1)
        print(line.hex(), end=' ')
        write_json.write( line)

It still shows me the wxwidgets path:

Code: Select all

0.452789	0.452789	hello
1.044898	1.044898	小苹果

This will return the byte values (This version is for Linux and will need adapting for Windows)

Code: Select all

import os
import sys
PIPE_BASE = '/tmp/audacity_script_pipe.'
WRITE_NAME = PIPE_BASE + 'to.' + str(os.getuid())
READ_NAME = PIPE_BASE + 'from.' + str(os.getuid())
EOL = '\n'
write_pipe = open(WRITE_NAME, 'w')
read_pipe = open(READ_NAME, 'rb')

def send_command(command):
    """Send a single command."""
    print("Send: >>> \n"+command)
    write_pipe.write(command + EOL)
    write_pipe.flush()

def get_response():
    """Return the command response."""
    eolCount = 0
    bytes = bytearray([])
    while eolCount < 2:
        byte = read_pipe.read(1)
        bytes += byte
        if byte == b'\n' :
            eolCount +=1
        else:
            eolCount = 0
    print(bytes.hex())

send_command("GetInfo: Type=Labels")
get_response()

The problem though is that the returned bytes may not all be valid UTF-8, so I don't know how you would decoded it.

Following pipe_test.py code adapted:

Code: Select all

WRITE_NAME = '\\\\.\\pipe\\ToSrvPipe'
READ_NAME = '\\\\.\\pipe\\FromSrvPipe'
EOL = '\r\n\0'

This is my output. You still can see 4 zero bytes followed by the path "633a5c777877696467...", just like the last time I tried.

Code: Select all

C:\tmp>python get-labels.py
Send: >>>
GetInfo: Type=Labels

What output do you get from two labels, each containing: 不要你
What output do you get from the "GetInfo" menu command with those labels?

The arrow is pointing at the path.

I'm trying to work out where the encoding / decoding is going wrong.
I can't copy and paste digits from a screenshot.

Just like my old post (above), there are 4x zero bytes then followed by a path.

You're getting less on Windows than I do on Linux. Your version appears to be completely choking on the Unicode characters.

For the current version of Audacity, it appears that the script pipe module does not support Unicode at all on Windows. I've written to the developers about this, but I'm not hopeful of Unicode support being added any time soon, unless the problem was just an oversight that can be easily fixed.

I'll write back if I get more information. Sorry I couldn't be more help.

Thank you for your time
