  • How can I modify complex command-line argument strings in Perl?

    - by mmccoo
    I have a command line that I'm trying to modify to remove some of the arguments. What makes this complex is that I can have nested arguments. Say that I have this: $cmdline = "-a -xyz -a- -b -xyz -b- -a -xyz -a-" I have three different -xyz flags that are to be interpreted in two different contexts. One is the -a context and the other is the -b context. I want to remove the "a" -xyz's but leave the ones in the "b" -xyz. in the above case, I want: -a -a- -b -xyz -b- -a -a- Alternately, if I have: -a -123 -a- -b -xyz -b- -a -xyz -a-" I want: -a -123 -a- -a -xyz -a- -b -xyz -b- -a -a- It's this second case that I'm stuck on. How can I most effectively do this in Perl?

  • Can't understand example using continuations

    - by Matt Fenwick
    I'm reading the r6rs Scheme report and am confused by the explanation of continuations (I find it to be too dense and lacking of examples for a beginner). What is this code doing and how does it evaluate to 4? Why does call/cc want an argument that's a function of one argument? How is call/cc's argument used? (+ 1 (call-with-current-continuation (lambda (escape) (+ 2 (escape 3))))) =? 4 This example is from section 1.11 - Continuations.

  • Problem in migrating to LAMP from XAMPP.. Memory limit error

    - by Geshan
    I was using XAMPP for my local machine but as I wanted to run applications like mysql work bench and some test frameworks I decided to switch to LAMP self install. I'm using ubuntu and followed the instructions at: https://help.ubuntu.com/community/ApacheMySQLPHP But the problem is LAMP is consuming too much of my memory (RAM) I've allocated 124 MB currently but still it gives me memory exhausted error when I run Drush (Drupal command line). When I do drush cc to clear cache it give me the following: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 122880 bytes) in /var/www/----/sites/all/modules/ubercart/uc_order/uc_order.order_pane.inc on line 150 Call Stack: 0.0020 185624 1. {main}() /opt/drush/drush.php:0 0.0254 1303672 2. drush_main() /opt/drush/drush.php:37 0.2674 5107784 3. drush_bootstrap() /opt/drush/drush.php:71 0.2676 5109872 4. _drush_bootstrap_drupal_full() /opt/drush/includes/environment.inc:173 0.2676 5151032 5. drupal_bootstrap() /opt/drush/includes/environment.inc:655 0.3030 7739048 6. _drupal_bootstrap() /var/www/missmoti/includes/bootstrap.inc:989 0.3122 8855792 7. _drupal_bootstrap_full() /var/www/missmoti/includes/bootstrap.inc:1078 0.3445 12387320 8. module_load_all() /var/www/missmoti/includes/common.inc:2608 0.5194 32586544 9. drupal_load() /var/www/missmoti/includes/module.inc:14 0.5251 33361112 10. include_once('/var/www/missmoti/sites/all/modules/ubercart/uc_order/uc_order.module') /var/www/-----/includes/bootstrap.inc:617 Drush command could not be completed.

  • Preffered lambda syntax?

    - by Roger Alsing
    I'm playing around a bit with my own C like DSL grammar and would like some oppinions. I've reserved the use of "(...)" for invocations. eg: foo(1,2); My grammar supports "trailing closures" , pretty much like Ruby's blocks that can be passed as the last argument of an invocation. Currently my grammar support trailing closures like this: foo(1,2) { //parameterless closure passed as the last argument to foo } or foo(1,2) [x] { //closure with one argument (x) passed as the last argument to foo print (x); } The reason why I use [args] instead of (args) is that (args) is ambigious: foo(1,2) (x) { } There is no way in this case to tell if foo expects 3 arguments (int,int,closure(x)) or if foo expects 2 arguments and returns a closure with one argument(int,int) - closure(x) So thats pretty much the reason why I use [] as for now. I could change this to something like: foo(1,2) : (x) { } or foo(1,2) (x) -> { } So the actual question is, what do you think looks best? [...] is somewhat wrist unfriendly. let x = [a,b] { } Ideas?

  • How to create a closure and pass in variable length argument list?

    - by Jian Lin
    We can create a closure p by capturing the arguments in the scope in the following code: var p = function() { }; if (typeof(console) != 'undefined' && console.log) { p = function() { console.log(arguments); }; } but the arguments are passed like an array to console.log, instead of passed one by one as in console.log(arguments[0], arguments[1], arguments[2], ... Is there a way to expand the arguments and pass to console.log like the way above? Note that p = console.log; works well in Firefox and IE 8 but not on Chrome.

  • CFMX6.1 deplying on Websphere 6.1 Server: Error 500: The Security service is not available.

    - by ahiru
    I am deploying a CFMX6.1 application to a Websphere 6.1 server. The server starts up without any errors but when I goto the CF Adminstrator page (or any cf page) I get the following error: Error 500: The Security service is not available. Can you deploy CFMX6.1 to WS6.1? My searches on the internets seem to say yes and no. As far as the error goes I normally end up at a page that lists the same error with stacktrace but no answers. Am I just searching using the wrong question? Thanks.

  • What is the best way to marshal a char array function argument?

    - by Seh Hui 'Felix' Leong
    Let say that given the following signature in LegacyLib.dll: int Login(SysInst *inst, char username[8], char password[6]); The simple way to marshal this function in C# would be: [DllImport("LegacyLib.dll", CharSet=CharSet.Ansi)] public static extern int Login(ref SysInst inst, string username, string password); The problem of doing it in a such a naive way is that the managed string we passed into the username or password parameter could be longer than the array bounds and this could potentially cause a buffer overrun in LegacyLib.dll. Is there a better way which overcomes this problem? i.e. is there any quick [MarshalAs(…)] magic that I could use to counter that?

  • Liskov principle: violation by type-hinting

    - by Elias Van Ootegem
    According to the Liskov principle, a construction like the one below is invalid, as it strengthens a pre-condition. I know the example is pointless/nonsense, but when I last asked a question like this, and used a more elaborate code sample, it seemed to distract people too much from the actual question. //Data models abstract class Argument { protected $value = null; public function getValue() { return $this->value; } abstract public function setValue($val); } class Numeric extends Argument { public function setValue($val) { $this->value = $val + 0;//coerce to number return $this; } } //used here: abstract class Output { public function printValue(Argument $arg) { echo $this->format($arg); return $this; } abstract public function format(Argument $arg); } class OutputNumeric extends Output { public function format(Numeric $arg)//<-- VIOLATION! { $format = is_float($arg->getValue()) ? '%.3f' : '%d'; return sprintf($format, $arg->getValue()); } } My question is this: Why would this kind of "violation" be considered harmful? So much so that some languages, like the one I used in this example (PHP), don't even allow this? I'm not allowed to strengthen the type-hint of an abstract method but, by overriding the printValue method, I am allowed to write: class OutputNumeric extends Output { final public function printValue(Numeric $arg) { echo $this->format($arg); } public function format(Argument $arg) { $format = is_float($arg->getValue()) ? '%.3f' : '%d'; return sprintf($format, $arg->getValue()); } } But this would imply repeating myself for each and every child of Output, and makes my objects harder to reuse. I understand why the Liskov principle exists, don't get me wrong, but I find it somewhat difficult to fathom why the signature of an abstract method in an abstract class has to be adhered to so much stricter than a non-abstract method. Could someone explain to me why I'm not allowed to hind at a child class, in a child class? The way I see it, the child class OutputNumeric is a specific use-case of Output, and thus might need a specific instance of Argument, namely Numeric. Is it really so wrong of me to write code like this?

  • How can I pipe a large amount of data as a runtime argument?

    - by Zombies
    Running an executable JAR on a linux platform here. The program it self works on a somewhat large amount of data, basically a list of URLs... could be up to 2k. Currently I get this from a simple DB call. But I was thinking that instead of creating a new mode and writing SQL to get a new result set and having to redploy everytime, I could just make the program more robust by passing in the result set (the list of URLs) that need to be worked on... so, within a linux environment, is there a pain-free/simple way to get the result set and pass it in dynamically? I know file i/o is one, but it doesn't seem to be effecient because each file has to be named, as well more logic to handle grabbing the correct file, creating a file with a unique name, etc.

  • 'Bug in Mailman version 2.1.12'

    - by davorg
    I'm working on setting up a server running Plesk 10.4.4 Update #13 on Centos 6.2. I've configured Mailman and now I want to set up some mailing lists. I've created a list in the Plesk control panel, but when I try to administer the new list (by visiting http://lists.[domain].com/mailman/admin/[listname] I see the following error: Bug in Mailman version 2.1.12 We're sorry, we hit a bug! Please inform the webmaster for this site of this problem. Printing of traceback and other system information has been explicitly inhibited, but the webmaster can find this information in the Mailman error logs. I see exactly the same error if I try to go to the list info page at http://lists.[domain].com/mailman/listinfo/[listname]. I would follow the instructions and look in the error logs, but I can't find them. I would expect to find a file at /var/log/mailman/error, but there's nothing there. My test list seems to work correctly. It sends all the expected email. It's just the web pages for the list that seem to be broken. Has anyone else seen this? Any suggestions for tracking down and fixing the problem? p.s. I think I've chosen the correct Stack Exchange site, but it this question would be better asked elsewhere, please let me know. Update: I got to the bottom of this, so I'm documenting the answer in case anyone else has the same problem. The fact that I couldn't find the error log was the clue. The problem was that the Mailman process didn't have permissions to create an error log. And it seems that if Mailman can't create an error log then it will respond to any web request with this error page. Creating an error log file (in /var/log/mailman/error) and giving it the correct permissions fixed the problem.

Error for B: HTTP Error 400.0 - Bad Request ASP.NET detected invalid characters in the URL. The last part of the URL after /Show/ is the result after the text is being sent through HttpUtility.UrlEncode() so, according to Microsoft it is URL Encoded correctly. If I user HttpUtility.UrlPathEncode() rather than HttpUtility.UrlEncode() I get the A2 results. But B ends up looking like: http://192.168.1.96/TVCMS-CVJZ/cms/View.aspx/Show/'&$#funky**!!~''%20page which is still wrong. Does Microsoft know how to URL Encode at all? Is there a function someone has written up to do it the correct way?
