  • How to control utf-8 string paddings

    - by Kev
    I got three UTF-8 stings: hello, world hello, ?? hello, ?rld I only want the first 10 chars so that the bracket in one column: [hello, wor] [hello, ? ] [hello, ?r] In console: width('??')==width('worl') width('? ')==width('wor') #a white space behind '?' python's format() doesn't help when UTF-8 chars mixed in >>> for s in ['[{0:<{1}.{1}}]'.format(s, 10) for s in ['hello, world', 'hello, ??', 'hello, ?rld']]: ... print(s) ... [hello, wor] [hello, ?? ] [hello, ?rl] So, I wonder if there is a standard way to do the UTF-8 padding staff?

  • How do I write to command line from a WPF application?

    - by ben
    Hi I know how to write to console but if I write to console in my program and call my program from the command line it won't display anything. How do I make it so that when I say Console.WriteLine or Console.Out.Writeline ir prints to the command prompt from which it was called and not somewhere else? Once again I know how to do Console.WriteLine so it's not that :-p unless I'm doing it wrong. From what I can tell it's probably something to do with Console.SetOut(TextWriter t) this is a WPF application and I need it to post its data to the command line while still retaining the GUI at startup. I've triple checked and my code hits the print lines, I can actually see the lines being printed to the Visual Studio output window, it just won't display in the command line when I run it manually without VS. If possible I need to conditionally have the console display. ie if run from command line (or even with command arguments), display or post to the prompt, otherwise do not.

  • Programmatic binding of accelerators in wxPython

    - by Inductiveload
    I am trying to programmatically create and bind a table of accelerators in wxPython in a loop so that I don't need to worry about getting and assigning new IDs to each accelerators (and with a view to inhaling the handler list from some external resource, rather than hard-coding them). I also pass in some arguments to the handler via a lambda since a lot of my handlers will be the same but with different parameters (move, zoom, etc). The class is subclassed from wx.Frame and setup_accelerators() is called during initialisation. def setup_accelerators(self): bindings = [ (wx.ACCEL_CTRL, wx.WXK_UP, self.on_move, 'up'), (wx.ACCEL_CTRL, wx.WXK_DOWN, self.on_move, 'down'), (wx.ACCEL_CTRL, wx.WXK_LEFT, self.on_move, 'left'), (wx.ACCEL_CTRL, wx.WXK_RIGHT, self.on_move, 'right'), ] accelEntries = [] for binding in bindings: eventId = wx.NewId() accelEntries.append( (binding[0], binding[1], eventId) ) self.Bind(wx.EVT_MENU, lambda event: binding[2](event, binding[3]), id=eventId) accelTable = wx.AcceleratorTable(accelEntries) self.SetAcceleratorTable(accelTable) def on_move(self, e, direction): print direction However, this appears to bind all the accelerators to the last entry, so that Ctrl+Up prints "right", as do all the other three. How to correctly bind multiple handlers in this way?

  • How can I access the int values of an object in an NSMutableArray?

    - by Daniel
    I try to access some values in a NSMutableArray I created, but I only get some numbers (address?) if I try to access them. I was able to initialize an array and can add and change objects with [myNSMutableArray addObject:[NSNumber numberWithInt:10]] and [myNSMutableArray replaceObjectAtIndex:0 withObject:[NSNumber numberWithInt:47] I also can print the value at index [0] with NSLog(@"%@", [myNSMutableArray objectAtIndex:0]); and I get 47 as expected. But how can I access the integer value of the object in the array so I can save it tomyIntValue?

    template<unsigned int n> struct Factorial { enum { value = n * Factorial<n-1>::value}; }; template<> struct Factorial<0> { enum {value = 1}; }; int main() { std::cout << Factorial<5>::value; std::cout << Factorial<10>::value; } above program computes factorial value during compile time. I want to print factorial value at compile time rather than at runtime using cout. How can we achive printing the factorial value at compile time? I am using VS2009. Thanks!

  • What is the better Shebang Line to use ?

    - by Anonymous
    What is better/faster to use: #! perl or #! perl.exe or #! fullpath/perl(/perl.exe) or #! partialpath/perl(/perl.exe) ? And, when using "#! perl", when it works on a particular system, what is the print() for showing the full path to perl.exe, that could be included into the Shebang Line ? And, if using a /path/path/perl, are "*" or "..." allowed to be used for the folders ?

  • How can I profile a subroutine without using modules?

    - by Zaid
    I'm tempted to relabel this question 'Look at this brick. What type of house does it belong to?' Here's the situation: I've effectively been asked to profile some subroutines having access to neither profilers (even Devel::DProf) nor Time::HiRes. The purpose of this exercise is to 'locate' bottlenecks. At the moment, I'm sprinkling print statements at the beginning and end of each sub that log entries and exits to file, along with the result of the time function. Not ideal, but it's the best I can go by given the circumstances. At the very least it'll allow me to see how many times each sub is called. The code is running under Unix. The closest thing I see to my need is perlfaq8, but that doesn't seem to help (I don't know how to make a syscall, and am wondering if it'll affect the code timing unpredictably). Not your typical everyday SO question...

  • Partially flattening a list

    - by alj
    This is probably a really silly question but, given the example code at the bottom, how would I get a single list that retain the tuples? (I've looked at the itertools but it flattens everything) What I currently get is: ('id', 20, 'integer') ('companyname', 50, 'text') [('focus', 30, 'text'), ('fiesta', 30, 'text'), ('mondeo', 30, 'text'), ('puma', 30, 'text')] ('contact', 50, 'text') ('email', 50, 'text') what I would like is a single level list like: ('id', 20, 'integer') ('companyname', 50, 'text') ('focus', 30, 'text') ('fiesta', 30, 'text') ('mondeo', 30, 'text') ('puma', 30, 'text') ('contact', 50, 'text') ('email', 50, 'text') def getproducts(): temp_list=[] product_list=['focus','fiesta','mondeo','puma'] #usually this would come from a db for p in product_list: temp_list.append((p,30,'text')) return temp_list def createlist(): column_title_list = ( ("id",20,"integer"), ("companyname",50,"text"), getproducts(), ("contact",50,"text"), ("email",50,"text"), ) return column_title_list for item in createlist(): print item Thanks ALJ

  • identify the input that is multiple of 11 and odd or even java

    - by Bolor Ch
    i am trying to write code to determine the nature of input using if statement only. The nature of input could be following: a multiple of 11 even or odd. For the code below, when I enter my input, it does not display the result as "input:NOT:ODD". Also how can I check multiple conditions with if statement? (else is not considered) import java.util.Scanner; public class test { public static void main( String args[] ) { Scanner input = new Scanner( System.in ); int x; int EO; int Mult; System.out.print ( "Enter value: " ); x = input.nextInt(); EO = x % 2; Mult = x % 11; if (EO > 0 && Mult > 0) { System.out.printf ("%d:NOT:ODD"); } } }

  • Forking Multiple Apps Under Python Subprocess

    - by noxtion
    Hello all. I have been looking through Google and SO for something that could help me solve this but I have run into a block. I am a bit new to Python but I am looking for a way to run multiple apps that will continuously run in the background. For example, I need 4 apps to start up with a param -appnum set to a different value. I would like to use python to count up and then start up a new app that will continue to run. I assumed I would use subprocess but I feel a bit overwhelmed by the documentation. I also plan to have the app print out sequences of numbers and would like to redirect this to a file. I noticed some of the SO questions talked about this, but I am a little confused on what to do. -Mike

  • passing session id via url

    I'm trying to get my script to use url session id instead of cookies. The following page is not picking up the variable in the url as the session id. I must be missing something.

  • Weird behavior in referring to global variable. Is this a bug in javascript? Surely it isn't!

    - by Chandan .
    Consider the following piece of code. <html> <body> <script> var x = 5; //globally declared function showX() { alert("x="+x); //trying to display global value var x=10; //trying to create and initialize a local x } </script> <input type = "button" value="Show X" onclick="showX()"> </body> </html> The alert statement shows 'x=undefined'. And doesn't print the global value of x as expected. An equivalent java code would display 5! So, is it a bug? If not then how does one explain that behavior?

  • Perl - string matching issue

    - by user2886545
    I have a problem I cannot understand. I have this string: gene_id "siRNA_Z27kG1_20543"transcript_id "siRNA_Z27kG1_20543_X_1";tss_id "TSS124620" And I want to change the gene_id. So, I have the following code: if ($line =~ /;transcript_id "([A-Za-z0-9:\-._]*)(_[oxOX][_.][0-9]*)";/) { $num = $2; $line =~ s/gene_id "([A-Za-z0-9:\-._]*)";/gene_id "$1$num";/g; print $new $line."\n"; } The aim of my code is to change siRNA_Z27kG1_20543 for siRNA_Z27kG1_20543_X_1. However, my code does not produce that output. Why? I can't understand that. My regex needs to be as it is because I match other strings (this time with success). Thanks.

  • Problem mapping data located in a NSMutableArray

    - by Graeme
    I have an NSMutableArray which contains some addresses which I need to map using Apple's MapKit SDK which I can't seem to get to load. The NSLog keeps telling me that the data source is (null) and a 0x0 error displays when I attempt to print out the array. Any ideas? The data is parsed and stored from another class, perhaps I'm not linking it across properly? The data is originally gathered from an RSS feed, bought into the app with an IMporter class, and then displayed in a table view. I want to be able to connect into that data with my mapping class, but am struggling to do so.

  • Why this code does not do what I mean?

    - by Mike
    $w = 'self-powering'; %h = (self => 'self', power => 'pau?', ); if ($w =~ /(\w+)-(\w+)ing$/ && $1~~%h && $2~~%h && $h{$2}=~/?$/) { $p = $h{$1}.$h{$2}.'ri?'; print "$w:"," [","$p","] "; } I expect the output to be self-powering: selfpau?ri? But what I get is: self-powering: [ri?] My guess is something's wrong with the code $h{$2}=~/?$/ It seems that when I use $h{$2}!~/?$/ Perl will do what I mean but why I can't get "self-powering: selfpau?ri?"? What am I doing wrong? Any ideas? Thanks as always for any comments/suggestions/pointers :)

  • Can I use string concatenation to define a class CONST in PHP?

    - by selfsimilar
    I know that you can create global constants in terms of each other using string concatenation: define('FOO', 'foo'); define('BAR', FOO.'bar'); echo BAR; will print 'foobar'. However, I'm getting an error trying to do the same using class constants. class foobar { const foo = 'foo'; const foo2 = self::foo; const bar = self::foo.'bar'; } foo2 is defined without issue, but declaring const bar will error out Parse error: syntax error, unexpected '.', expecting ',' or ';' I've also tried using functions like sprintf() but it doesn't like the left paren any more than the string concatenator '.'. So is there any way to create class constants in terms of each other in anything more than a trivial set case like foo2?

  • Java: PriorityQueue returning incorrect ordering from custom comparator??

    - by Michael Simpson
    I've written a custom comparator to compare my node classes, but the java priority queue is not returning my items in the correct order. Here is my comparator: public int compare(Node n1, Node n2){ if (n1.getF() > n2.getF()){ return +1; } else if (n1.getF() < n2.getF()){ return -1; } else { // equal return 0; } } Where getF returns a double. However after inserting several Nodes into the priority queue, I print them out using: while(open.size() > 0) { Node t = (Node)(open.remove()); System.out.println(t.getF()); } Which results in: 6.830951894845301 6.830951894845301 6.0 6.0 5.242640687119285 7.4031242374328485 7.4031242374328485 8.071067811865476 Any ideas why this is so? Is my comparator wrong? Thanks. Mike

  • How do I access a DIV from javascript, if ASP.NET mangles its ID?

    - by Rising Star
    I have a web page that contains a "div" element. On the page, there is javascript to reference the div: document.getElementById('divId'). This was working fine until another developer redesigned the page to use an ASP master page. Now, document.getElementById('divId') returns null. It appears that ASP.net prepends some characters to the names of elements within contents forms when you use a master page. How can I know what the id of the div is when the page loads? Update Allow me to give a specific example to clarify the question: My page had a div with ID divNotice. After changing my page to use a master page, I see when I print the source to the page that renders that the div ID is ctl00_ContentPlaceHolder1_divNotice. My question is, how am I supposed to know what the div ID is going to be when the framework is done with it?

  • Checking if a string's characters are ascending alphabetically and its ascent is evenly spaced python

    - by FRU5TR8EDD
    So need to check if a string's characters are ascending alphabetically and if that ascent is evenly spaced. a = "abc" b = "ceg" So a is alphabetically ascending and it's spacing is 1 (if you convert to the ordinal values they are 97,98,99). And b is also alphabetically ascending and it's spacing is 2 (99,101,103). And I am sticking with the following code: a = 'jubjub' words1 = [] ords = [ord(letter) for letter in a] diff = ords[1] - ords[0] for ord_val in range(1, len(ords)-1): if diff > 0: if ords[ord_val + 1] - ords[ord_val] == diff: if a not in words1: words1.append((a, diff)) print words1 How come 'jubjub' works, 'ace' works, but 'catcat' doesn't?
