Programming :: Python - Find And Replace While Typing In Raw Input

Apr 30, 2010

I'm writing a program in Python that presents a place for the user to input one-line of text (using raw_input). I need, however, as the user types, for certain words to be replaced, even before the user hits enter.

I try to make an animation so you can see what I mean, here the word "pig" gets replaced with "sheep":
>I|
>I |
>I l|
>I li|
>I lik|
>I like|
>I like |
>I like t|
>I like to|
>I like to |
>I like to e|
>I like to ea|
>I like to eat|
>I like to eat |
>I like to eat p|
>I like to eat pi|
>I like to eat pig|
>I like to eat sheep|

Note, the user never typed "sheep", the program replaced "pig" with "sheep" as soon as they finished typing the word "pig". The user did not use "Enter". Is this at all possible in Python?

OpenSUSE Install :: Create A Instance On A Windows 7 PC And Use Dual-boot?

Nov 23, 2010

I'm trying to create a Linux instance on a Windows 7 PC and use dual-boot. I have created 64GB of space for Linux. Is this enough? When I boot from the live DVD and go through the setup, I get stuck setting up the unassigned space as a linux partition. I don't understand what the setup is trying to tell me and I'm afraid I'll wipe out Windows 7. The message I get says there isn't enough space even though the unassigned available area is 64GB. I am very timid about following what Yast2 is telling me because to my untrained eye it appears the setup wants to use my entire hard drive. Where can I find more information about the disk setup section of the installation process?

Ubuntu :: Links From Widgets - Task Bar Shows An Instance Of Konqueror And Another Instance Of Firefox

Feb 15, 2010

I have KDE 4.4 and Firefox 3.6. Whenever I click a link from a plasmoid widget, it tries to open Konqueror and another instance of Firefox. The page actually loads in the opened Firefox window, but the task bar shows an instance of Konqueror and another instance of Firefox, that keeps loading for a while then close. See image below:

I currently have setup the browser default application as "firefox". If I set this option to use the default application, it opens in Konqueror and I don't see additional windows in the task bar. If I change the option to "firefox %u", then it exhibit the same issue, but the process is much faster, so the loading windows don't stay for long in the task bar. Additionally, it opens the link on a new Firefox window and opens the page twice. Although Konqueror is not loaded, the bouncing icon next to the mouse pointer shows up and stay for a while.

General :: Define A Keyboard Layout / Input Method For Ubuntu In Python?

Jun 20, 2010

defining keyboard layouts in linux (ubuntu 10.04 here). there does not seem to be any easy, graphical way to define keyboard mappings (except for keyboardlayouteditor, but frankly, i do not understand the installation description.i am using an apple aluminum keyboard with a german layout, but no matter what i do the (<>) and (^) keys are always swapped (i did manage to change the default behavior for the f1...f12 keys from multimedia back to 'ordinary', application-centric... all you have to do is add the line echo 2 > /sys/module/hid_apple/parameters/fnmode to /etc/rc.local... this is so bloody obvious i am ashamed i had to search the web for this!).

adding to my distress, i find the chinese IMEs a horror (not a single one of the many i tried does anywhere come near google pinyin for windows), and have gotten neither ibus nor scime to work in a satisfactory way for me. i find linux keyboard handling a morass. i know this must be one of the hardest problems in computer science, since this subject gets so convoluted no matter whether its on windows or in-the-browser javascript. as a linguist i am well aware of the inherent complications proper text handling poses, but looking at descriptions how to configure xkb makes building interstellar spaceships look like a cakewalk.

find a place in the system where keystrokes are recorded;read out those codes (could be scan codes or character codes) using a daemon (implemented in python; i heard you have to listen to IOCTL or somesuch); when certain code combinations appear, switch them to do what you want;applications now get to see a X where formerly the got to see a U and vice versa;profit!

Is there a place, in ubuntu / linux systems that does allow reading out keyboard codes? Is there a way to block processing of such keyboard actions until an intercepting daemon has processed them? Would such an interceptor work for a broad range of use cases? like on the command line, in a gtk app, in wine, in firefox and so on? An alternative would actually be to grok keyboardlayouteditor, so if someone could post about a readable, complete installation instruction or point out installable packages, that'd be great, too.

Effectively, I am trying to make an array such that, for a point in any row of a 2D matrix ("Matrix(i,j)"), the command "next_i[i]" will return "(i+1)%L", where L is the number of data points in the row. This will enable me to select a point to the right of any point in the matrix: "Matrix(next[i],j)"

Programming :: How To Set Up Global Class In JAVA?

May 10, 2011

I've had to do some code in java, a language I'm very much unfamiliarly with so please excuse my incorrect use of terms. The basic outline of my problem is I create a class object as a local within a swing button function it works fine. If I create it as a global ( with I think I need to do ) within main, then prototype it with the other swing objects at the bottom of the file when it is called it causes a host of problems. I think the easiest way is to show it.

Programming :: How To Modify ArrayList From Outside Of Class?

Mar 10, 2010

Okay so I'm working on a program here as I'm learning java,I have an array that is initialized with 5 objects that are hard coded. I have made a GUI that takes the input needed and creates an object with those values.I need to add that object to the ArrayList that I have previously made.Okay, so I have three classes, guiclass.java, main.java and gladiator.java Objects are made and defined in "gladiator".Main contains my public static void main section, launches my gui, creates my five hard coded objects, creates my ArrayList and adds my five hard coded objects to the ArrayList.Now, I need to add the object that I generated in the guiSection [action Listener]to the ArrayList that I created in my main class's public static void main string... section. Problem is my arraylist "cannot be resolved" from guiclass.
