python clipboard 块移动

这一直没发现在linux下好用的块移动的编辑器

因为你可能在网上copy下来的代码是这样的需要把整个代码向前移4个字符自己写了这样一个程式来实现这个功能

>>> from sqlalchemy import Column, Integer, String
>>> class User(Base):
...     __tablename__ = 'users'
...
...     id = Column(Integer, primary_key=True)
...     name = Column(String)
...     fullname = Column(String)
...     password = Column(String)

step

1. copy clipboard data to file

2. read data from file

3. block move

4.save file

5. copy file data to clipboard

说明

用到xclip这个软件

ubuntu下可以直接 sudo apt-get install xclip

#copy clipboard data to from.txt
xclip -o > from.txt

#copy data to clipboard
cmd = 'cat to.txt | xclip -selection clipboard'
os.popen(cmd)

block_move.py

#!/usr/bin/env python

import sys
import os

del_num = 3
if len(sys.argv)>1:
    del_num = int(sys.argv[1])

#copy clipboard data to from.txt
cmd = 'xclip -o > from.txt'
os.popen(cmd).read()

to_data = []
print "from.txt:"
with open('from.txt') as fp:  
    for line in fp:  
        print line,
        to_line = line[del_num:]
        to_data.append(to_line)

to_file = open('to.txt', 'w')
data = ''.join(to_data)
to_file.write(data)
to_file.close()

#copy data to clipboard
cmd = 'cat to.txt | xclip -selection clipboard'
os.popen(cmd)

print ""
print "to.txt:"
print data
print "del_num:", del_num 
print "ok."
