How to make a dialog box (three options like quit/OK/Cancel) in blender and processing the text entered through python or in C. I'm unable to find any good tutorial on this. Any help....?
A quick and dirty way is to use zenity command (should be included by default in any python distribution). Try this short example script, it works in my Blender 2.69 on Ubuntu 14.04.
import bpy # bpy or bge does not matter
import subprocess as SP
# call an OS subprocess $ zenity --entry --text "some text"
# (this will ask OS to open a window with the dialog)
res=SP.Popen(['zenity','--entry','--text',
'please write some text'], stdout=SP.PIPE)
# get the user input string back
usertext=str(res.communicate()[0][:-1])
# adjust user input string
text=usertext[2:-1]
print("I got this text from the user: %s"%text)
See the zenity --help for more complex dialogs
blender doesn't offer things like dialogs.
Answers to This previous question on external modules may be helpful.
class DialogOperator(bpy.types.Operator)
bl_idname = "object.dialog_operator"
bl_label = "Save Before You QUIT!"
def execute(self, context):
message = " You didn't saved yet "
self.report({'INFO'}, message)
print(message)
return {'FINISHED'}
def invoke(self, context, event):
return context.window_manager.invoke_props_dialog(self)
class DialogPanel(bpy.types.Panel)
bl_label = "Dialog"
bl_space_type = "VIEW_3D"
bl_region_type = "UI"
def draw(self, context):
self.layout.operator("object.dialog_operator")
But this is only for creating a dialog window. after this have to insert buttons in this code.If anyone known this try to post the answer. At the same time I'm also trying to sort out this.

I am playing around with Selenium to get screenshots of websites to view them safely.
The original code I found and tweaked was like this and works.
from selenium import webdriver
br = webdriver.PhantomJS()
br.get('http://www.google.com')
br.save_screenshot('screenshot.png')
br.quit
It gives you a screenshot of the website
I wanted to get user input so that I did not have the VI the file overtime I need a screenshot of a URL this is what I changed the code too.
#!/usr/bin/python
import re
import sys
from selenium import webdriver
br = webdriver.PhantomJS()
br.get_user_input =raw_input('Enter URL:')
br.save_screenshot('screenshot.png')
br.quit
Now it ask for the URL and you input it in the program runs and finishes and even creates the screenshot.png file but its blank
try to use a chrome canary (if you need headless browser). you don't have to use a selenium.
make_screen = '''#!/usr/bin/env bash
test -f ./chrome-linux/chrome && echo "chrome exists" || unzip chrome-linux.zip
./chrome-linux/chrome --headless --disable-gpu --virtual-time-budget=7000 --hide-scrollbars --screenshot=dir/screens/{screen_prod}.png --window-size=1200,2000 {link_prod}'''.format(screen_prod = screen_prod, link_prod = link_prod)
Here is the Answer to your Question:
There is a small bug in your code. You havn't called the get() method with your WebDriver instance br.
As a solution, (to avoid Law of Demeter) I have broken up that line in to two. Took the url from the user as an input in the first line. In the next line passed the url as an argument to get() method. Next it takes a proper snapshot and saves it within Screenshots sub-directory. Here is the working code block :
from selenium import webdriver
br = webdriver.PhantomJS(executable_path="C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe")
user_input = input('Enter URL : ')
br.get(str(user_input))
br.save_screenshot('./Screenshots/my_next_screenshot.png')
br.quit
The output on my console is:
Enter URL : http://google.com
Process finished with exit code 0

I am using paramiko for ssh interactive commands. I am able to successfully send all the required commands. I am stuck on one issue. i need somebody help to automate this task.
Issue is on output, i will get 4 options, from this options, i need to move to the required option by using arrow keys and then press enter button to select that option.
Please let me know if anybody knows about this.
import paramiko
import time
import os
ssh=paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('server',port=22,username='user',password='pass123')
print("connected to the linux machine from windows machine.")
channel=ssh.invoke_shell()
channel_data = str()
while True:
if channel.recv_ready():
channel_data += channel.recv(9999).decode(encoding='utf_8', errors='strict')
os.system('cls')
print("##### Device Output #####")
print("\n",channel_data)
print("\n #####################")
else:
continue
time.sleep(5)
if channel_data.endswith('[root#home ~]# '):
channel.send('somecommand\n')
#highlight and then press enter button to select that option. please help for below code
ifelse channel_data.endswith('I am trying to choose this option from the list'):
channel.send('\n')
We need to send the keycode. for down arrow key, "[B 1b 5b 42" is key code.
Below is the link for complete list of keycode mapping.

I recently started using MonkeyRunner to test the UI of my Android application (I am also using Espresso but wanted to play around with MonkeyRunner). The problem that I am having is that I am unable to enter text into EditText fields using the automation script.
The script navigates through my app perfectly but it doesn't seem to actually enter any text on call of the MonkeyRunner.type() command.
Please find my script below.
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice
from com.android.monkeyrunner.easy import EasyMonkeyDevice, By
import commands
import sys
import os
# starting the application and test
print "Starting the monkeyrunner script"
# connection to the current device, and return a MonkeyDevice object
device = MonkeyRunner.waitForConnection()
easy_device = EasyMonkeyDevice(device)
apk_path = device.shell('pm path com.mysample
if apk_path.startswith('package:'):
print "application installed."
else:
print "not installed, install APK"
device.installPackage('/MySample/MySample.apk')')
package ="com.mysample"
activity = ".SampleActivity"
print "Package: " + package + "Activity: " + activity
print "starting application...."
device.startActivity(component=package + '/' + activity)
print "...component started"
device.touch(205,361, "DOWN_AND_UP")
device.type("This is sample text")
MonkeyRunner.sleep(1)
result = device.takeSnapshot()
result.writeToFile("images/testimage.png",'png')
As you can see from the script above the text This is sample text should be placed in the EditText box. Both the emulator and screenshot that is taken show no text in the text field.
Am I missing a step or just doing something incorrectly?
Any help would be greatly appreciated!
I would rather use AndroidViewClient/culebra to simplify the task.
Basically, you can connect your device with adb and then run
culebra -VC -d on -t on -o myscript.py
The script obtains references to all of the visible Views. Edit the script and add at the end
no_id10.type('This is sample text')
no_id10.writeImageToFile('/tmp/image.png')
No need to worry about View coordinates, no need to touch and type, no need to add sleeps, etc.
NOTE: this is using no_id10 as an example, the id for your EditText could be different
First of all, I would not use the MonkeyRunner.sleep command, but I would rather use the time package and the time.sleep command. Just import the package
import time
and you should be good to go.
Moreover, I suggest you should wait some time between device.touch and device.type. Try with
device.touch(205,361, "DOWN_AND_UP")
time.sleep(1)
device.type("This is sample text")
I have nagios alerts set up to come through jabber with an http link to ack.
Is is possible there is a script I can run from a terminal on a remote workstation that takes the hostname as a parameter and acks the alert?
./ack hostname
The benefit, while seemingly mundane, is threefold. First, take http load off nagios. Secondly, nagios http pages can take up to 10-20 seconds to load, so I want to save time there. Thirdly, avoiding slower use of mouse + web interface + firefox/other annoyingly slow browser.
Ideally, I would like a script bound to a keyboard shortcut that simply acks the most recent alert. Finally, I want to take the inputs from a joystick, buttons and whatnot, and connect one to a big red button bound to the script so I can just ack the most recent nagios alert by hitting the button lol. (It would be rad too if the button had a screen on the enclosure that showed the text of the alert getting acked lol)
Make fun of me all you want, but this is actually something that would be useful to me. If I can save five seconds per alert, and I get 200 alerts per day I need to ack, that's saving me 15 minutes a day. And isn't the whole point of the sysadmin to automate what can be automated?
Thanks!
Yes, it's possible to ack nagios by parsing /var/lib/nagios3/retention.dat file.
See :
#!/usr/bin/env python
# -*- coding: utf8 -*-
# vim:ts=4:sw=4
import sys
file = "/var/lib/nagios3/retention.dat"
try:
sys.argv[1]
except:
print("Usage:\n"+sys.argv[0]+" <HOST>\n")
sys.exit(1)
f = open(file, "r")
line = f.readline()
c=0
name = {}
state = {}
host = {}
while line:
if "service_description=" in line:
name[c] = line.split("=", 2)[1]
elif "current_state=" in line:
state[c] = line.split("=", 2)[1]
elif "host_name=" in line:
host[c] = line.split("=", 2)[1]
elif "}" in line:
c+=1
line = f.readline()
for i in name:
num = int(state[i])
if num > 0 and sys.argv[1] == host[i].strip():
print(name[i].strip("\n"))
You simply have to put the host as parameter, and the script will displays the broken services.
I'm new to Python and I simply don't know how to handle this specific problem:
I'm trying to run an executable (named ros_M5e.py) that's located in the directory /opt/ros/diamondback/stacks/hrl/hrl_rfid/src/hrl_rfid/ros_M5e.py (annoyingly long filepath, I know, but necessary). However, within the ros_M5e.py file there is a call to another file that is further up the file path: from hrl.hrl_rfid.msg import RFIDread. The directory msg indeed is located at /opt/ros/diamondback/stacks/hrl/hrl_rfid/ and it does indeed contain the file RFIDread. However, whenever I try to execute ros_M5e.py I get this error:
Traceback (most recent call last):
File "/opt/ros/diamondback/stacks/hrl/hrl_rfid/src/hrl_rfid/ros_M5e.py", line 37, in <module>
from hrl.hrl_rfid.msg import RFIDread
ImportError: No module named hrl.hrl_rfid.msg
Would someone with some expertise please shine some light on this problem for me? It seems like just a rudimentary file location problem, but I just don't know the appropriate Python conventions to fix it. I've tried putting the ros_M5e.py file in the same directory as the files it calls and changing the filepaths but to no avail.
Thanks a lot,
Khiya
Sure, I can help you get it up and running.
From the StackOverflow posting, it would seem that you're checking out the stack to /opt/ros/diamondback. This is no good, as it is a system path. You need to install into your local path. The reason for "readonly" on the repository is that you do not have permissions to make changes to the code -- it will still work just fine for you on your local machine. I spent a fair amount of time showing how to use this package (at least the python version) here:
http://www.ros.org/wiki/hrl_rfid
I'll try to do a quick run-through for installing it.... Run the following commands:
cd
mkdir sandbox
cd sandbox/
svn checkout http://gt-ros-pkg.googlecode.com/svn/trunk/hrl/hrl_rfid hrl_rfid (double-check that this checkout works OK!)
Add the following line to the bottom of your bashrc to tell ROS where to find the new package. (You may use "gedit ~/.bashrc")
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:$HOME/sandbox/hrl_rfid
Now execute the following:
roscd hrl_rfid (did you end up in the correct directory?)
rosmake hrl_rfid (did it make without errors?)
roscd hrl_rfid/src/hrl_rfid
At this point everything is actually installed correctly. By default, ros_M5e.py assumes that the reader is located at "/dev/robot/RFIDreader". Unless you've already altered udev rules, this will not be the case on your machine. I suggest running through the code:
http://www.ros.org/wiki/hrl_rfid
using iPython (a command-line python prompt that will let you execute python commands one at a time) to make sure everything is working (replace /dev/ttyUSB0 with whatever device your RFID reader is connected as):
import lib_M5e as M5e
r = M5e.M5e( '/dev/ttyUSB0', readPwr = 3000 )
r.ChangeAntennaPorts( 1, 1 )
r.QueryEnvironment()
r.TrackSingleTag( 'test_tag_id_' )
r.ChangeTagID( 'test_tag_id_' )
r.QueryEnvironment()
r.TrackSingleTag( 'test_tag_id_' )
r.ChangeAntennaPorts( 2, 2 )
r.QueryEnvironment()
This means that the underlying library is working just fine. Next, test ROS (make sure "roscore" is running!), by putting this in a python file and executing:
import lib_M5e as M5e
def P1(r):
r.ChangeAntennaPorts(1,1)
return 'AntPort1'
def P2(r):
r.ChangeAntennaPorts(2,2)
return 'AntPort2'
def PrintDatum(data):
ant, ids, rssi = data
print data
r = M5e.M5e( '/dev/ttyUSB0', readPwr = 3000 )
q = M5e.M5e_Poller(r, antfuncs=[P1, P2], callbacks=[PrintDatum])
q.query_mode()
t0 = time.time()
while time.time() - t0 < 3.0:
time.sleep( 0.1 )
q.track_mode( 'test_tag_id_' )
t0 = time.time()
while time.time() - t0 < 3.0:
time.sleep( 0.1 )
q.stop()
OK, everything works now. You can make your own node that is tuned to your setup:
#!/usr/bin/python
import ros_M5e as rm
def P1(r):
r.ChangeAntennaPorts(1,1)
return 'AntPort1'
def P2(r):
r.ChangeAntennaPorts(2,2)
return 'AntPort2'
ros_rfid = rm.ROS_M5e( name = 'my_rfid_server',
readPwr = 3000,
portStr = '/dev/ttyUSB0',
antFuncs = [P1, P2],
callbacks = [] )
rospy.spin()
ros_rfid.stop()
Or, ping me back and I can tweak ros_M5e.py to take an optional "portStr" -- though I recommend making your own so that you can name your antennas sensibly. Also, I highly recommend setting udev rules to ensure that the RFID reader always gets assigned to the same device: http://www.hsi.gatech.edu/hrl-wiki/index.php/Linux_Tools#udev_for_persistent_device_naming
BUS=="usb", KERNEL=="ttyUSB*", SYSFS{idVendor}=="0403", SYSFS{idProduct}=="6001", SYSFS{serial}=="ftDXR6FS", SYMLINK+="robot/RFIDreader"
If you do not do this... there is no guarantee that the reader will always be enumerated at /dev/ttyUSBx.
Let me know if you have any further problems.
~Travis Deyle (Hizook.com)
PS -- Did you modify ros_M5e.py to "from hrl.hrl_rfid.msg import RFIDread"? In the repo, it is "from hrl_rfid.msg import RFIDread". The latter is correct. As long as you have your ROS_PACKAGE_PATH correctly defined, and you've run rosmake on the package, then the import statement should work just fine. Also, I would not recommend posting ROS-related questions to StackOverflow. Very few people on here are going to be familiar with the ROS ecosystem (which is VERY complex). Please post questions here instead:
http://answers.ros.org/
http://code.google.com/p/gt-ros-pkg/issues/list
You need to make sure that following are true:
Directory /opt/ros/diamondback/stacks/ is in your python path.
/opt/ros/diamondback/stacks/hr1 contains __init__.py
/opt/ros/diamondback/stacks/hr1/hr1_rfid contians __init__.py
/opt/ros/diamondback/stacks/hr1/hr1_rfid/msg contians __init__.py
As the asker explained in comments that the RFIDRead does not have .py extension, so here is how that can be imported.
import imp
imp.load_source('RFIDRead', '/opt/ros/diamondback/stacks/hr1/hr1_rfid/msg/RFIDRead.msg')
Check out imp documentation for more information.
