Import from klipper/plain text

[DUOLabs333]

Is your feature request related to a problem? Please describe.
Since #1692 got fixed, I want to move back to copyq from klipper (KDE's clipboard).

Describe the solution you'd like
So, is there a way to import from klipper directly? klipper saves its history as a .lst file, so maybe you can import from there? With a bit of work, you can also export klipper history is a plain text file, so maybe that could work as well (you would obviously lose date information, but order should still be preserved).

Describe alternatives you've considered

The history lst file seems to be some internal data format of Klipper. I'm not going to support this in CopyQ.

I took a quick peek at the implementation and to parse the file you would need to use Qt framework. Below is a simple script to import the data file with Python and PyQt5 library (it does not support import "url" and "image" type of objects, only simple text). Argument is path to the .lst file:

#!/usr/bin/env python3
import sys
from subprocess import PIPE, Popen

from PyQt5.QtCore import QByteArray, QDataStream, QFile, QIODevice

COMMAND = ["copyq", "tab", "klipper", "add", "-"]

filename = sys.argv[1]
f = QFile(filename)
if not f.open(QFile.ReadOnly):
    raise RuntimeError(f"Failed to open file {filename}: {f.errorString()}")

try:
    file_stream = QDataStream(f)
    crc = file_stream.readUInt32()
    print(f"CRC: {crc}")
    data = QByteArray()
    file_stream >> data
finally:
    f.close()

history_stream = QDataStream(data, QIODevice.ReadOnly)
version = history_stream.readString()
print(f"version: {version}")

while True:
    type_ = history_stream.readQString()
    if not type_:
        break

    if type_ == "string":
        text = history_stream.readQString()
        print(f"Adding: {text}")
        with Popen(COMMAND, stdin=PIPE) as p:
            p.stdin.write(text.encode("utf-8"))
            p.stdin.close()
    else:
        print(f"WARNING: Type {type_} is not supported")
