Question

我可以在Buffers菜单中切换行号。但是我希望它默认启用。我在询问左侧的行号，而不是状态栏中的行号。

Answer 1

请在.jedrc文件中插入以下代码。

public define global_mode_hook (hook_name)
{
    set_line_number_mode (1);
}

- ）

Answer 2

opt的答案是正确的，但代码应位于.jedrc的底部。应该有一行这样的内容：

import cv2
import numpy as np
from pynput.keyboard import Key, Controller
import time

keyboard = Controller()

wc = cv2.VideoCapture(0)
time.sleep(2)

for i in range(40):
    ret, img = wc.read()

img = cv2.flip(img,1)
imgGray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
faces = faceCascade.detectMultiScale(imgGray, 1.1, 4)
for (x, y, w, h) in faces:
   cv2.rectangle(img, (x,y), (x + w, y + h), (255, 0, 0), 2)
centre = [int((x + w + x)/2), int((y + h + y)/2)]
    


faceCascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml')
wc = cv2.VideoCapture(0)
    
# Read until video is completed
while(wc.isOpened()):
  # Capture frame-by-frame
  ret, img = wc.read()
  img = cv2.flip(img,1)
  if ret == True:
    
    imgGray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
    faces = faceCascade.detectMultiScale(imgGray, 1.1, 4)
    for (x, y, w, h) in faces:
        cv2.rectangle(img, (x,y), (x + w, y + h), (255, 0, 0), 2)
    centre_new = [int((x + w + x)/2), int((y + h + y)/2)]
    cv2.circle(img, (centre_new[0], centre_new[1]), 0, (0,0,255), 5)
    
    if  centre_new[0] - centre[0] > 100 : 
        keyboard.press(Key.right)
        keyboard.release(Key.right)
        print('right')

    if  centre_new[0] - centre[0] < -100 : 
        keyboard.press(Key.left)
        keyboard.release(Key.left)
        print('left')

    if  centre_new[1] - centre[1] < -100 : 
        keyboard.press(Key.up)
        keyboard.release(Key.up)
        print('up') 
    
    if  centre_new[1] - centre[1] > 100 : 
        keyboard = Controller()
        keyboard.press(Key.down)
        keyboard.release(Key.down)
        print('down')

    # Display the resulting frame
    cv2.imshow('Face',img)

    # Press Q on keyboard to  exit
    if cv2.waitKey(1) & 0xFF == ord('q'):
      break
  
  # Break the loop
  else: 
    break

# When everything done, release the video capture object
wc.release()
# Closes all the frames
cv2.destroyAllWindows()

默认情况下，在jed编辑器的左侧启用行号
