  • More elegant way to parse inline variables in strings

    - by Tom
    Currently I have this: function parse_string($string, $variables){ extract($variables); return eval('return "'. addcslashes($string, '"') .'";'); } So I can input this string: 'Hi {$name}, my name is {$own_name}' Together with this array: array('name' => 'John', 'own_name' => 'Tom') And get this back: 'Hi John, my name is Tom'   I've never liked this eval() approach but it works and it's fast (faster than regex at least). Question: Is there a more elegant way to do this (faster than using regex) in PHP5?

  • How to select a MenuItem programatically

    - by Shaung
    I am trying to add a global shortcut to a gtk.MenuItem which has a sub menu. Here is my code: import pygtk, gtk import keybinder dlg = gtk.Dialog('menu test') dlg.set_size_request(200, 40) menubar = gtk.MenuBar() menubar.show() menuitem = gtk.MenuItem('foo') menuitem.show() menubar.append(menuitem) mitem = gtk.MenuItem('bar') mitem.show() menu = gtk.Menu() menu.add(mitem) menu.show() menuitem.set_submenu(menu) def show_menu_cb(): menubar.select_item(menuitem) keybinder.bind('<Super>i', show_menu_cb) dlg.vbox.pack_start(menubar) dlg.show() dlg.run() When I press the key menu pops up, I can then select items in the sub menu or press Esc to make it disappear. But after that the menuitem keeps selected and other windows never get input focus again. I have to click on the menuitem twice to get everything back normal.

  • How to find validity of a string of parentheses, curly brackets and square brackets?

    - by Rajendra
    I recently came in contact with this interesting problem. You are given a string containing just the characters '(', ')', '{', '}', '[' and ']', for example, "[{()}]", you need to write a function which will check validity of such an input string, function may be like this: bool isValid(char* s); these brackets have to close in the correct order, for example "()" and "()[]{}" are all valid but "(]", "([)]" and "{{{{" are not! I came out with following O(n) time and O(n) space complexity solution, which works fine: Maintain a stack of characters. Whenever you find opening braces '(', '{' OR '[' push it on the stack. Whenever you find closing braces ')', '}' OR ']' , check if top of stack is corresponding opening bracket, if yes, then pop the stack, else break the loop and return false. Repeat steps 2 - 3 until end of the string. This works, but can we optimize it for space, may be constant extra space, I understand that time complexity cannot be less than O(n) as we have to look at every character. So my question is can we solve this problem in O(1) space?

  • why can't I call .update on a MessageDigest instance

    - by Arthur Ulfeldt
    when i run this from the repl: (def md (MessageDigest/getInstance "SHA-1")) (. md update (into-array [(byte 1) (byte 2) (byte 3)])) I get: No matching method found: update for class java.security.MessageDigest$Delegate the Java 6 docs for MessageDigest show: update(byte[] input) Updates the digest using the specified array of bytes. and the class of (class (into-array [(byte 1) (byte 2) (byte 3)])) is [Ljava.lang.Byte; Am I missing something in the definition of update? Not creating the class I think I am? Not passing it the type I think I am?

  • Passing a web service an unknown number of parameters

    - by Billyhole
    I'm relatively new to utilizing web services. I'm trying to create one that will be accepting data from a ASP.Net form whose input controls are created dynamically at runtime and I don't how many control values will be getting passed. I'm thinking I'll be using jQuery's serialize() on the form to get the data, but what do I have the web service accept for a parameter? I thought maybe I could use serializeArray(), but still I don't know what type of variable to accept for the JavaScript array. Finally, I was thinking that I might need to create a simple data transfer object with the data before sending it along to the web service. I just didn't wanna go through with the DTO route if there was a much simpler way or an established best practice that I should follow. Thanks in advance for any direction you can provide and let me know I wasn't clear enough, or if you have any questions.

  • How can I configure different worker pools using celery?

    - by Chris R
    I need to deploy a queued execution service with (generally) the following three classes of worker: A periodic, low-priority job class that takes a long time and can be processed serially; these jobs should only use 0..2 workers in the system at most. A periodic, deadline-sensitive job class that take a short to medium amount of time (say, topping out at 5 minutes) An ad-hoc job class, that is higher priority than #1, but can interleave with #2. Any workers from class #2 that are inactive when this type of job comes in should handle it, without ever starving the pool of workers for #2 All three job classes are the same task, the only difference between them is how they're requested; they'll take the same input and generate the same output, but each one has different performance guarantees. How can I implement this using celery?

  • Javascript form validation events

    - by user307922
    Hi All, I am making a small form for a php app and had a question regarding javascript validation. What is the best event to run the javascript validation on the input value? Is it the "focusout" event? I used "focusout" to originally but it creates problems when the user hits enter while they are still focused on any particular field in the form. Should I run the js validation when the user clicks submit? Just looking for some advice. Thanks! Chuck

  • what this `^` mean here in solr

    - by Rahul Mehta
    I am confuse her but i want to clear my doubt. I think it is stupid question but i want to know. Use a TokenFilter that outputs two tokens (one original and one lowercased) for each input token. For queries, the client would need to expand any search terms containing upper case characters to two terms, one lowercased and one original. The original search term may be given a boost, although it may not be necessary given that a match on both terms will produce a higher score. text:NeXT ==> (text:NeXT^10 OR text:next) what this ^ mean here . http://wiki.apache.org/solr/SolrRelevancyCookbook#Relevancy_and_Case_Matching

  • SSIS web service task producing "object reference" error

    - by gfrizzle
    Our care management system uses a web service to import data. I've successfully executed one of its methods using soapUI, and now I want to replicate this with an SSIS 2008 web service task, but I'm running into a problem. I've created the "HTTP Connection Manager" successfully, and specified the location of the "WSDLFile", but when I go to the Input tab and select the Service from the dropdown (there is only one), I get an "Object reference not set to an instance of an object" error, and and the Method dropdown is empty. Any idea what this is trying to tell me?

  • How to get the Doctype Declaration in Xerces-C when using SAX2 ?

    - by ArtB
    I am using SAX2 from Xerces-C to read an XML document. However, I would like to check the Doctype declaration (if there is any) to make sure that the XML file is in the format I am expecting. I have tried the unparsedEntityDecl and notationDecl methods from the DTDHandler, and EntityResolver seems to be more low-level than what I am looking for. My motivation is for this is to be able to confirm that the input is of the format I am expecting so that I can differentiate between documents which produce no output and those that are entirely of the wrong format.

  • Why doesn't JFreeCharts correctly connect the points in my xy-line graph?

    - by Javajava
    /Each letter A,T,G,C represents a direction for the plot to graph. Specifically, “A” means move right, “T” is move down, “C” is move up, and “G” is move left.

  • Convert a complicated string into an array in php

    - by Patrick Beardmore
    I have a php variable that comes from a form that needs tidying up. I hope you can help. The variable contains a list of items (possibly two or three word items with a space in between words). I want to convert it to a comma separated list with no superfluous white space. I want the divisions to fall only at commas, semi-colons or new-lines. Blank cannot be an item. Here's a comprehensive example (with a deliberately messy input): Variable In: "dog, cat ,car,tea pot,, ,,, ;;(++NEW LINE++)fly, cake" Variable Out "dog,cat,car,tea pot,fly,cake" Can anyone help?

  • Any way to optimize this MySQL query?

    - by manyxcxi
    My table looks like this: `MyDB`.`Details` ( `id` bigint(20) NOT NULL, `run_id` int(11) NOT NULL, `element_name` varchar(255) NOT NULL, `value` text, `line_order` int(11) default NULL, `column_order` int(11) default NULL ); I have the following SELECT statement in a stored procedure SELECT RULE ,TITLE ,SUM(IF(t.PASSED='Y',1,0)) AS PASS ,SUM(IF(t.PASSED='N',1,0)) AS FAIL FROM ( SELECT a.line_order ,MAX(CASE WHEN a.element_name = 'PASSED' THEN a.`value` END) AS PASSED ,MAX(CASE WHEN a.element_name = 'RULE' THEN a.`value` END) AS RULE ,MAX(CASE WHEN a.element_name = 'TITLE' THEN a.`value` END) AS TITLE FROM Details a WHERE run_id = runId GROUP BY line_order ) t GROUP BY RULE, TITLE; *runId is an input parameter to the stored procedure. This query takes about 14 seconds to run. The table has 214856 rows, and the particular run_id I am filtering on has 162204 records. It's not on a super high power machine, but I feel like I could be doing this more efficiently. My main goal is to summarize by Rule and Title and show Pass and Fail count columns.

  • form tag - is it required on ajax sites?

    - by benpage
    i recently was working on an ASP.NET MVC site that basically serves static html and uses ajax gets to return data to the page when inputs are changed. there is actually no posting or getting from an html input tag on the pages at all. (it is a specific style of site that is not used by the general public, so having compatibility problems for people without javascript is not an issue) after designing the site, i realised that i hadn't even included any form tags. as the site does not use any direct posts or gets, and apart from it being just good html design, i wondered, in my particular situation, if there was any point to having any form tags on the page?

  • Optimizing simple search script in PowerShell

    - by cc0
    I need to create a script to search through just below a million files of text, code, etc. to find matches and then output all hits on a particular string pattern to a CSV file. So far I made this; $location = 'C:\Work*' $arr = "foo", "bar" #Where "foo" and "bar" are string patterns I want to search for (separately) for($i=0;$i -lt $arr.length; $i++) { Get-ChildItem $location -recurse | select-string -pattern $($arr[$i]) | select-object Path | Export-Csv "C:\Work\Results\$($arr[$i]).txt" } This returns to me a CSV file named "foo.txt" with a list of all files with the word "foo" in it, and a file named "bar.txt" with a list of all files containing the word "bar". Is there any way anyone can think of to optimize this script to make it work faster? Or ideas on how to make an entirely different, but equivalent script that just works faster? All input appreciated!
