  • writing a fast parser in python

    - by panzi
    I've written a hands-on recursive pure python parser for a some file format (ARFF) we use in one lecture. Now running my exercise submission is awfully slow. Turns out by far the most time is spent in my parser. It's consuming a lot of CPU time, the HD is not the bottleneck. I wonder what performant ways are there to write a parser in python? I'd rather not rewrite it in C. I tried to use jython, but that decreased performance a lot! The files I parse are partially huge ( 150 MB) with very long lines. My current parser only needs a look-ahead of one character. I'd post the source here but I don't know if that's such a good idea. After all the submission deadline has not jet ended. But then, the focus in this exercise is not the parser. You can choose whatever language you want to use and there already is a parser for Java.

    - by oshafran
    Hi I am using excanvas.js that is used with flot jquery graphs. When in FF or chrome the graphs show great. on IE I get this error: Unknown runtime error excanvas.min.js, line 144 character 21 el.getContext = getContext; // Remove fallback content. There is no way to hide text nodes so we // just remove all childNodes. We could hide all elements and remove // text nodes but who really cares about the fallback content. el.innerHTML = ''; el in the stack is DispHTMLUnknownElement What can that be? Thank you?

  • XSLT: Disable output escaping in an entire document.

    - by Kragen
    I'm trying to generate some C# code using xslt - its working great until I get to generics and need to output some text like this: MyClass<Type> In this case I've found that the only way to emit this is to do the following: MyClass<xsl:text disable-output-escaping="yes">&lt;</xsl:text>Type<xsl:text disable-output-escaping="yes">&gt;</xsl:text> Where: Often it all needs to go on one line, otherwise you end up with line breaks in the generated code In the above example I technically could have used only 1 <xsl:text />, however usually the type Type is given by some other template, e.g: <xsl:value-of select="@type" /> I don't mind having to write &lt; a lot, but I would like to avoid writing <xsl:text disable-output-escaping="yes">&lt;</xsl:text> for just a single character! Is there any way of doing disable-output-escaping="yes" for the entire document?

  • How to print non-ASCII characters in Python

    - by Roman
    I have a problem when I'm printing (or writing to a file) the non-ASCII characters in Python. I've resolved it by overriding the str method in my own objects, and making "x.encode('utf-8')" inside it, where x is a property inside the object. But, if I receive a third-party object, and I make "str(object)", and this object has a non-ASCII character inside, it will fail. So the question is: is there any way to tell the str method that the object has an UTF-8 codification, generically? I'm working with Python 2.5.4.

  • Returning control codes as JSON to a jquery ajax json call

    - by Graham
    I want to know if it is possible to return ascii control codes in JSON format from classic ASP to a jQuery ajax call. This is my jQuery call: $.ajax({ url: "/jsontest.asp", type: "POST", cache: false, dataType: "json", complete: function(data) { var o = $.parseJSON(data.responseText.toString()); }, error: function(data1, data2) { alert("There has been an error - please try again"); } }); This is my called page: {"val1":123,"val2","abcdef"} The above works fine, but if I change my called page to include ascii character 31 (1F) like so: {"val1":123,"val2","abc\x1Fdef"} then I get the alert in my error function. Can this be done, and if so, how please. Note: I'm using jQuery 1.7.1 and both IIS 6 and IIS 7 I have tried: \x1f, %1f, and \u001f

  • Using only alphanumeric characters(a-z) inside toCharArray

    - by Aaron
    Below you will find me using toCharArray in order to send a string to array. I then MOVE the value of the letter using a for statement... for(i = 0; i < letter.length; i++){ letter[i] += (shiftCode); System.out.print(letter[i]); } However, when I use shiftCode to move the value such as... a shifted by -1; I get a symbol @. Is there a way to send the string to shiftCode or tell shiftCode to ONLY use letters? I need it to see my text, like "aaron", and when I use the for statement iterate through a-z only and ignore all symbols and numbers. I THINK it is as simple as... letter=codeWord.toCharArray(a,z); But trying different forms of that and googling it didn't give me any results. Perhaps it has to do with regex or something? Below you will find a complete copy of my program; it works exactly how I want it to do; but it iterates through letters and symbols. I also tried finding instructions online for toCharArray but if there exists any arguments I can't locate them.

  • Overflow on UILabels

    - by jkeesh
    I have a table view that I am customizing and I am adding a UILabel as a subview of the contentView, and I want the number of lines to be relatively consistent. I set the numberOfLines property to be 3 so it can't go more than that, but there are still some that overflow onto the 4th line. If it overflows, I want to add a a trailing ... How can I figure out if it overflows? I've tried truncating at different character counts of my string, but since I am using lineBreakMode = UILineBreakModeWordWrap the number of characters doesn't really predict the number of lines. Is there a way to find out the number of lines your UILabel is using?

  • Python encoding for pipe.communicate

    - by Brian M. Hunt
    I'm calling pipe.communicate from Python's subprocess module from Python 2.6. I get the following error from this code: from subprocess import Popen pipe = Popen(cwd) pipe.communicate( data ) For an arbitrary cwd, and where data that contains unicode (specifically 0xE9): Exec. exception: 'ascii' codec can't encode character u'\xe9' in position 507: ordinal not in range(128) Traceback (most recent call last): ... stdout, stderr = pipe.communicate( data ) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 671, in communicate return self._communicate(input) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 1177, in _communicate bytes_written = os.write(self.stdin.fileno(), chunk) This is happening, I presume, because pipe.communicate() is expecting ASCII encoded string, but data is unicode. Is this the problem I'm encountering, and i sthere a way to pass unicode to pipe.communicate()? Thank you for reading! Brian

  • InvalidAttributeValueException when using non-ascii characters in JNDI

    - by matdan
    Hi, I have some trouble using JNDI since it accepts only 7-bits encoded parameters. I am trying to change an LDAP entry using JNDI with the following code : Attribute newattr = new BasicAttribute("userpassword", password); ModificationItem[] mods = new ModificationItem[1]; mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, newattr); context.modifyAttributes("uid=anID,ou=People,o=MyOrganisation,c=com", mods); If my password contains only ascii characters, it works perfectly, but if I use a non-ascii character, like "à", I have this error message : javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 19 - The value is not 7-bit clean: à]; My ldap supports those characters so I guess it comes from JNDI. Does anyone know how to fix that? Am I supposed to convert my parameter? How can I do that easily? Thanks

  • invalid token error while parsing an XML file with UTF-8 encoding

    - by Niranjan
    invalid token error while parsing an XML file with UTF-8 encoding. This error is coming when it encountered extended ASCII character 'â' { "â", "â" }. When I have changed the encoding from UTF-8 to ISO-8859-1 the parsing is successful. But my application should support UTF-8, ASCII and extended ASCII characters. What should I do for this? Any ideas are welcome. Thanks in Advance for your time and solution.

  • Can someone explain this "endian-ness" function for me?

    - by Mike
    Write a program to determine whether a computer is big-endian or little-endian. bool endianness() { int i = 1; char *ptr; ptr = (char*) &i; return (*ptr); } So I have the above function. I don't really get it. ptr = (char*) &i, which I think means a pointer to a character at address of where i is sitting, so if an int is 4 bytes, say ABCD, are we talking about A or D when you call char* on that? and why? Would some one please explain this in more detail? Thanks. So specifically, ptr = (char*) &i; when you cast it to char*, what part of &i do I get?

  • Recieving server broadcast on mobile in real time

    - by Manjoor
    I have to write a simple mobile application that is able to recieve broadcast from a server, connected using GPRS, over a secure SSL connection. The amount of data mobile need to recieve is very small (about 100 character string for a single broadcast and maximum 10 broadcast per minute) I need to display it on screen and generate a alert sound (and vibrate the device). Client need not to send anything back to server. (ofcourse at the time of intialization the client app need to send some data for authorization) The target mobile plateform is symbion S60 and Blackberry. How can i do this? What tools, SDK and Third party framework (if needed) i should use? I am familier with java and network programming but not for mobile device.

  • JNI unsigned char to byte array

    - by Jeff Storey
    I'm working with a C++ library that stores image byte data in an array of unsigned characters. My jni function returns a jByteArray (which then gets converted to a BufferedImage on the java side), but I'm not sure how to fill the jByteArray from the unsigned character array (if it is possible). Can anyone provide a snippet for this last part to basically do this: // size is the size of the unsigned char array const int size = 100; unsigned char* buf = new unsigned char[size]; // buf gets passed to another library here to be populated jbyteArray bArray = env->NewByteArray(size); // now how do I get the data from buf to bArray? Thanks, Jeff

  • Inserting Newline from XML to Database

    I am trying to parse this xml document in which a newline is required for certain fields and must be inserted into the database with the newline. But I've been running into problems. 1)First Problem: \n Character The first problem I had was using the \n like below. <javascript>jquery_ui.js\nshadowbox_modal.js\nuser_profile.js\ntablesorter.js</javascript> The problem was in the database the field came out ot be jquery_ui.js\nshadowbox_modal.js\n... and when output into html it was jquery_ui.jsnshadowbox_modal.jsn............... 2) Then I tried actually having newlines in the xml <javascript>jquery_ui.js shadowbox_modal.js user_profile.js tablesorter.js</javascript> The problem was the output become %20%20%20%20%20%20%20%20%20%20shadowbox_modal.js, and so forth. So how can I get a newline to hold from xml when entered into a database and then output with the newline still?

  • Handling inverse kinematics: animation blending or math?

    - by meds
    I've been working for the past four days on inverse kinematics for my game engine. I'm working on a game with a shoestring budget so when the idea of inverse kinematics came up I knew I had to make it such that the 3D models bones would be mathematically changed to appear to be stepping on objects. This is causing some serious problems with my animation, after it was technically implemented the animations started looking quite bad when the character was wlaking up inclines or steps even though mathematically the stepping was correct and was even smoothly interpolating. So I was wondering, is it actually possible to get a smooth efficient inverse kinematic system based exclusively on math where bones are changed or is this just a wild goose chase and I should either solve the inverse kinematics problem with animation blending or don't do it at all?

  • Special kind of queue

    - by devoured elysium
    I am looking for something like a Queue that would allow me to put elements at the end of the queue and pop them out in the beggining, like a regular Queue does. The difference would be that I also need to compact the Queue from time to time. This is, let's assume I have the following items on my Queue (each character, including the dot, is an item in the Queue): e d . c . b . a (this Queue has 8 items) Then, I'd need for example to remove the last dot, so to get: e d . c . b a Is there anything like that in the Java Collection classes? I need to use this for a program I am doing where I can't use anything but Java's classes. I am not allowed to design one for myself. Currently I'm just using a LinkedList, but I thought maybe this would be more like a Queue than a LinkedList. Thanks

  • SQL for selecting only the last item from a versioned table

    - by Jeremy
    I have a table with the following structure: CREATE TABLE items ( id serial not null, title character varying(255), version_id integer DEFAULT 1, parent_id integer, CONSTRAINT items_pkey PRIMARY KEY (id) ) So the table contains rows that looks as so: id: 1, title: "Version 1", version_id: 1, parent_id: 1 id: 2, title: "Version 2", version_id: 2, parent_id: 1 id: 3, title: "Completely different record", version_id: 1, parent_id: 3 This is the SQL code I've got for selecting out all of the records with the most recent version ids: select * from items inner join ( select parent_id, max(version_id) as version_id from items group by parent_id) as vi on items.version_id = vi.version_id and items.parent_id = vi.parent_id Is there a way to write that SQL statement so that it doesn't use a subselect?

  • Alternative to Microsoft Agent / Fix for color issue?

    - by Rob P.
    I've got an app that does Text-To-Speech; but I wanted to show an animated face/character to go with it. I found a tutorial on Microsoft Agent and I implemented it in my vb.net app. The problem is with the transparency color. Unless I run application in compatibility mode/256 colors, the characters will appear with a purplish-pink background image instead of a transparent back-color. But running the app in 256 colors the rest of the app looks awfully out of place. First - is there something that works similar to MS Agent I can use that would be more appropriate? Second - if I'm still MS Agent - can I get the transparent color to work correctly without limiting myself to 256 colors?

  • Passing more than one argument in asp.net button in gridview

    - by MarceloRamires
    I have a TemplateField column in a gridview with a button inside of it. There is NO key value (surely that was not designed by me) , but in the other hand there aren't redundancies when comparing each single column, because they are events, and there is "starting date" and "ending date" of something that could not happen twice at the same time. I've already figured selecting with these values and all, but I just want the button to pass about five arguments to a given function. I've tested: <asp:Button CommandArgument='<%# Eval("day")%>' ID="Button2" runat="server" Text="Button" /> And it works properly, the day of the clicked row is passed, and could be retrieved through: e.CommandArgument.ToString(); in the GridView_RowCommand handler. How do I pass more than one argument? I've thought about concatenating with a separating character (wouldn't be that bad) but besides not knowing how to do it yet (didn't want to invest in a poor solution) I want a smarter one.
