Capture output from external C program with python GUI in realtime -

Capture output from external C program with python GUI in realtime -

I have a threaded program that I want to start using a Python GUI in a UNIX environment. By gathering the output from the C program, I want to change the status of the GUI.

For example, this is output using printf from my C program:

  Thread on tile: 2 on thread on the tile: Thread 3 on closed tile: Disabled Thread on tile 61: On current    I will update my GUI based on the output. What makes the problem difficult is that both my GUI and C program need to run together And updates in real time let me do the program with my GUI The command should also be able to send.  
 I am new to Python, C and Unix (I know, full stop status).  
 
       
  I have run this problem in the past (there really is not a satisfactory solution):  
  
 As suggested here, Take a look at this custom module:  
 Richard (Not enough representative for comment): The problem with pipes is that unless they are connected to an interactive terminal, they are completely buffered Are Means that through no one pipe the output to run programming with Python, which is certainly not qualify as real-time. Edit 2: Based on the link of Richard and what I did some earlier, I did it to me to treat it as a file object and only one line at a time It may be possible to manually loop over the pipe by reading:  
  import time from the sleep # value estimate Popen object is wait_time = 1 # 1 second, the same delay when `Trail: # or Whatever the situation you need line = proc.stdout.readline () There is, if the line! = '' And the line! = '\ N': parse_line_do_stuff) sleep (wait_time)    It believes that readline () is non-blocked, and further assumes that the pipes are in the most buffer, and then I can not even try it, I have never tried it.

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,     






c# - EventSource's response has a MIME type ("text/html") that is
not "text/event-stream" -



    When I try to hook my controller to EventSource, it keeps saying:    EventSource Response contains a MIME type ("text / html") that is not "text / event-stream" canceling connection.    I have created the following class to help in handling a handle and preparing the reaction.

android - How to build apk without eclipse or Modify the apk building
with a config file? -



    I want to create an APK with some big configurations with an XML file.  I want to know if there is any method which can control the APK's building process or encoding at our source, there is no way to create APK with our source from our source, with a slight variation based on our SQF XML file. . Or any other way to create an APK file    When the app is running, I do not want to read my config file every time, I have to include a change in the application        If you want to manually create your application:    If you are developing in Eclipse, then the ADT plugin The enhanced project as you make changes to the source code. Eclipse automatically produces an .apk file in the project's bin folder, so you do not need to do anything extra to generate .apk.   If you are developing in a non-eclipse environment, then you create your project with the Generated Build.xml Ant file in the project directory that creates ant file calls which automatically targets you for Call the buil...
