  • Problem about python import with error

    - by xiao
    Hello, I have write a small python module with one class and two functions. The skeleton of the module is as following: #file name: test_module.py class TestClass: @classmethod def method1(cls, param1): #to do something pass def __init__(self, param1): #to do something ... def fun1(*params): #to do something ... def fun2(*params): #to do something ... Another py file is a small script which imports function and class from the module, as following: import sys from test_module import TestClass, fun1, fun2 def main(sys_argv): li = range(5) inst1 = TestClass(li) fun1(inst1) fun2(inst1) return if __name__ == "__main__": main(sys.argv) But when I execute the script, it is broken with following message: ./script.py: line 4: syntax error near unexpected token `(' ./script.py: line 4: `def main(sys_argv):' I am not sure what the problem is. Is it a problem with import? But when I try to import the module in ipython, everything is just ok.

  • An simple Python extension in C

    - by celil
    I am trying to create a simple python extension module. I compiled the following code into a transit.so dynamic module #include <python2.6/Python.h> static PyObject* _print(PyObject* self, PyObject* args) { return Py_BuildValue("i", 10); } static PyMethodDef TransitMethods[] = { {"print", _print, METH_VARARGS, ""}, {NULL, NULL, 0, NULL} }; PyMODINIT_FUNC inittransit(void) { Py_InitModule("transit", TransitMethods); } However, trying to call this from python import transit transit.print() I obtain an error message File "test.py", line 2 transit.print() ^ SyntaxError: invalid syntax What's wrong with my code?

  • Git Status Across Multiple Repositories on a Mac

    - by eapen
    I have been searching for a solution to this for a while and have not found quite what I need. I have several Git Repositories in a folder on my Mac (OSX 10.6) and would like a script or tool that will loop through all the repositories and let me know if any of them needs "commit"-ing. This is my structure Sites   /project1   /project2   /project3 I want the tool to do a "git status" in Sites/project1, Sites/project2, Sites/project3 and let me know if Sites/project2 and Sites/project3 have changes or new files and needs to be Staged/committed The closest script I found that might be hackable is here: http://gist.github.com/371828 but even that script wouldn't run and I get an error: "syntax error near unexpected token `do" which might have been written for *nix.

  • How does tomcat set its executable file as a windows service?

    - by Wing C. Chen
    Firstly, I am not at all familiar with windows batch file programing. Recently I am curious about how tomcat sets itself as a windows service using a batch file. I downloaded the service.bat file from tomcat 6. However, I still don't understand some part of it. I guess this is the line that the batch actually register the exe file to the OS, is it right? Is there any syntax explanation? "%EXECUTABLE%" //IS//%SERVICE_NAME% --StartClass org.apache.catalina.startup.Bootstrap --StopClass org.apache.catalina.startup.Bootstrap --StartParams start --StopParams stop And is this used to remove the service? "%EXECUTABLE%" //DS//%SERVICE_NAME% And this is the setting of the parameters? "%EXECUTABLE%" //US//%SERVICE_NAME% --JvmOptions "-Dcatalina.base=%CATALINA_BASE%;-Dcatalina.home=%CATALINA_HOME%;-Djava.endorsed.dirs=%CATALINA_HOME%\endorsed" --StartMode jvm --StopMode jvm Thanks.

  • Howto write a class where a property can be accessed without naming it.

    - by SchlaWiener
    I have a (dump) question regarding VB/C# I often use third party classes where I can access a child object with only specifying the id or key. Example: Instead of writing: DataRow row = GetAPopulatedDataRowSomeWhere(); Object result = row.Items[1]; // DataRow has no Items property Object result = row.Items["colName"]; // Also not possible I use this code to access the members: DataRow row = GetAPopulatedDataRowSomeWhere(); Object result = row[1]; Object result = row["colName"]; Can someone tell me how a class has to look like to support this syntax? My own class has a Dictionary that I want to access this way. MyClass["key"]; // <- that's what I want MyClass.SubItems["key"]; // <- that's how I use it now

  • Error including image in Latex

    - by euphoria83
    I am getting the following error while compiling my Latex File : ! LaTeX Error: Cannot determine size of graphic in tree.jpg (no BoundingBox). Why do I get this error ? What has this to do with an .eps file ? Infact, I could compile it fine with MacTex on my machine. But when I submit it online to a scientific journal for publication, it compiles it on the server and sends me the resultant PDF which as all these error that prevent it from compiling. I am using the following syntax for including the images : \begin{figure}[!h] \begin{center} \scalebox{0.45}{ \includegraphics{tree.jpg}} \end{center} \caption{\small A sample} \label{tree} \end{figure} What should I do ? Could it be that their server is using an old compiler ? UPDATE : It finally worked. I converted the first image to PDF and the compilation happened perfectly. I guess it used the bounding box value from that PDF and applied it to all images.

  • Getting javascript mouse position relative to website prefferably without jQuery

    - by Constructor
    I've found this snippet on Ajaxian, but I can't seem to use the cursor.y (or cursor.x) as a variable and when the function is called as such it does not seem to work. Is there a syntax problem or something else? function getPosition(e) { e = e || window.event; var cursor = {x:0, y:0}; if (e.pageX || e.pageY) { cursor.x = e.pageX; cursor.y = e.pageY; } else { cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft; cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop; } return cursor; } I'd preffer not to use jQuery UI if possible, since I've always thaught of jQuery and librarys as a bit of an overkill for most JS programing.

  • C# method contents regex validation

    - by user258651
    I need to validate the contents of a C# method. I do not care about syntax errors. I do care about characters that will invalidate parsing of the rest of the code. For example: method() { /* valid comment */ /* <-- bad for (i..) { } for (i..) { <-- bad } I need to validate/fix any non-paired characters. This includeds /* */, { }, and maybe others. How should I go about this?

  • Python del() built-in can't be used in assignment?

    - by emcee
    I noticed a problem when I was trying to use del in a lambda to thin out a list of threads to just those running: map(lambda x: del(x) if not x.isAlive() else x, self.threads) Ignore for a second that this doesn't do anything, I'm just fooling around with map, reduce, and lambda. This fails with a syntax error at del(x). With some messing around, I think the problem is del() doesn't return a value. For example, this fails with the same error: b = 5 x = del(b) This doesn't, however: def rmThis(x): del(x) Which means I'm using this workaround: map(lambda x: rmThis(x) if not x.isAlive() else x, self.threads) So is the limitation just because del() doesn't return a value? Why not? I'm using python 2.6.2

  • jquery get the index of a row?

    - by KnockKnockWhosThere
    I'm trying to write a function that will do something if the the row index is 0, and then something else if the row index is greater than 0. The zero part is working, but I can't figure out the syntax for rows that have an index greater than 0. For the tr[0] row, I'm doing this: if($("#mytable > tbody > tr ").index(0)) { ... I tried: if($("#mytable > tbody > tr ").index() > 0 ) { But, that didn't work?

  • Problem with mysql query to replace a string

    - by alex
    I've used mysql's update replace function before, but even though I think I'm following the same syntax, I can't get this to work. Here's what I'm trying to do: UPDATE contained_widgets SET preference_values = REPLACE(preference_values, '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li>', '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li> <li> <a_href="/projects"><span class="not-tc">Projects</span></a></li>'); Query OK, 0 rows affected (0.00 sec) Rows matched: 77 Changed: 0 Warnings: 0 I don't see what I'm missing. Any help is appreciated. I edited "a " to "a_" because the site thinks I'm posting spam links otherwise.

  • Core Data table record count

    - by user339633
    I have an entity called Person and it has a relationship called participatingGames, to another entity called GameParticipant. I (apparently) can retrieve the number of matches in the GameParticipant entity using this simple code in the Person object I created from the entity in the model: [self.participatingGames count]; However, I'd just like to retrieve the number of Person records and one might guess the syntax for this is just as simple. I have lots of books including those by Jeff LaMarche, but those sources and what I find around here make me wonder if I need to set up a fetchedResultsController just to know the count of some entity. My background is in SQL, so of course it seems odd that what would take 15 seconds to code in any other environment seems like such a well-guarded secret in Core Data. I'm using iPhone SDK 3.1.4 under OSX 10.5.8 Suggestions?

  • Grouping a generic list via LINQ in VB.NET

    I need to take a collection and group it via Linq but all the examples I've seen fail in some manner or other with some syntax difference that I can't quite lick. My collection: Dim a As New List(Of ProcessAlert) a.Add(New ProcessAlert("0000112367", "[email protected]", "Alert", 2)) a.Add(New ProcessAlert("0000112367", "[email protected]", "Document", 2)) a.Add(New ProcessAlert("0000112367", "[email protected]", "Note", 2)) a.Add(New ProcessAlert("0000112367", "[email protected]", "Alert", 1)) a.Add(New ProcessAlert("0000112367", "[email protected]", "Document", 1)) a.Add(New ProcessAlert("0000112367", "[email protected]", "Note", 1)) Return a I need to turn this collection into a simple way to give this final outcome: "[email protected]", "Alert, Document, Note" "[email protected]", "Alert, Document, Note" Here's the definition of the ProcessAlert class: Public Class ProcessAlert Public LoanNumber As String Public EmailAddress As String Public AlertType As String Public AlertMethodID As Byte End Class Thanks in advance, CD

  • How does dereferencing of a function pointer happen?

    - by eSKay
    Why and how does dereferencing a function pointer just "do nothing"? This is what I am talking about: #include<stdio.h> void hello() { printf("hello"); } int main(void) { (*****hello)(); } From a comment over here: function pointers dereference just fine, but the resulting function designator will be immediately converted back to a function pointer And from an answer here: Dereferencing (in way you think) a function's pointer means: accessing a CODE memory as it would be a DATA memory. Function pointer isn't suppose to be dereferenced in that way. Instead, it is called. I would use a name "dereference" side by side with "call". It's OK. Anyway: C is designed in such a way that both function name identifier as well as variable holding function's pointer mean the same: address to CODE memory. And it allows to jump to that memory by using call () syntax either on an identifier or variable. How exactly does dereferencing of a function pointer work?

  • Rack::ResponseHeaders in rackup for Sinatra

    - by sevennineteen
    I think this is a very easy one, but I can't seem to get it right. Basically, I'm trying to use Rack middleware to set a default Cache-Control header into all responses served by my Sinatra app. It looks like Rack::ResponseHeaders should be able to do exactly what I need, but I get an error when attempting to use the syntax demonstrated here in my rackup file: use Rack::ResponseHeaders do |headers| headers['X-Foo'] = 'bar' headers.delete('X-Baz') end I was able to get Rack::Cache to work successfully as follows: use Rack::Cache, :default_ttl => 3600 However, this doesn't achieve exactly the output I want, whereas Rack::ResponseHeaders gives fine-grained control of the headers. FYI, my site is hosted on Heroku, and the required Rack gems are specified in my .gems manifest. Thanks! Update: After doing some research, it looks like the first issue is that Rack::ResponseHeaders is not found in the version of rack-contrib (0.9.2) which was installed. I'll start by looking into that.

  • Importing data from third party datasource (open architecture design )

    - by mare
    How would you design an application (classes, interfaces in class library) in .NET when we have a fixed database design on our side and we need to support imports of data from third party data sources, which will most likely be in XML? For instance, let us say we have a Products table in our DB which has columns Id Title Description TaxLevel Price and on the other side we have for instance Products: ProductId ProdTitle Text BasicPrice Quantity. Currently I do it like this: Have the third party XML convert to classes and XSD's and then deserialize its contents into strong typed objects (what we get as a result of this process is classes like ThirdPartyProduct, ThirdPartyClassification, etc.). Then I have methods like this: InsertProduct(ThirdPartyProduct newproduct) I do not use interfaces at the moment but I would like them to. What I would like is implement something like public class Contoso_ProductSynchronization : ProductSynchronization InsertProduct(ContosoProduct p) where ProductSynchronization will be an interface or abstract class. There will most likely be many implementations of ProductSynchronization. I cannot hardcode the types - classes like ContosoProduct, NorthwindProduct might be created from the third party XML's (so preferably I would continue to use deserialization). Hopefully someone will understand what I'm trying to explain here. Just imagine you are the seller and you have numerous providers and each one uses their own proprietary XML format. I don't mind the development, which will of course be needed everytime new format appears, because it will only require 10-20 methods to be implemented, I just want the architecture to be open and support that.

  • INSERT INTO ... SELECT FROM ... ON DUPLICATE KEY UPDATE

    - by dnagirl
    I'm doing an insert query where most of many columns would need to be updated to the new values if a unique key already existed. It goes something like this: INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, inact, inadur, inadist, smlct, smldur, smldist, larct, lardur, lardist, emptyct, emptydur) SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, t.inact, t.inadur, t.inadist, t.smlct, t.smldur, t.smldist, t.larct, t.lardur, t.lardist, t.emptyct, t.emptydur FROM tmp t WHERE uid=x ON DUPLICATE KEY UPDATE ...; //update all fields to values from SELECT, except for exp_id, created_by, location, animal, starttime, endtime I'm not sure what the syntax for the UPDATE clause should be. How do I refer to the current row from the SELECT clause?

  • CSS3 box-shadow + inset + RGBA

    - by mkotechno
    I'm doing some tests with new features of CSS3, but this combination only works in lastest versions of Chrome and Firefox, but not in Safari or Opera: box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); -webkit-box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); -moz-box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5); I really don't know if they fails in the box-shadow itself, in the inset parameter, or in RGBA color. It's a syntax error or simply Safari and Opera lacks on this?

  • Identifying PHP unused variables (in Emacs)?

    - by Roberto Aloi
    Is it somehow possible to identify unused variables in a PHP file in Emacs? With other languages, this is possible by using tools such as flymake. I've already enabled Flymake to show syntax errors for my PHP files on the fly, but still it's frustrating that PHP logic errors are sometimes due to situations like: <?php $foo = whatever(); $bar = something($fo); ... Note the typo on $foo that will contribute to the developer's headache and to his exorbitant use of coffee.

  • How do I get a right outer join in L2E?

    - by Dan
    I have two tables that I set up through the VS Entity Data Model Diagram tool. I'm trying to do a right outer join and it doesn't return results from the 2nd table. I have set up a 0..1 to MANY relationship from the diagram tool. When I run a Linq-To-Entities query, it still defaults to an INNER JOIN. From my understanding of entities, if I set up the relationship using VS, when I join the tables, it should automagically figure out the join syntax based on the relationship I supply. It doesn't seem to be doing that. I am using EF v1 (not Linq-to-Sql). Query I'm running: from s in SomeTable join t in SomeOtherTable on s.ID equals t.ID select new { s.MyFieldName, t.MyOtherFieldName }

  • IIS url rewrite rewriting all .asp to .html

    - by user335711
    I need to create rules for web.config that will rewrite all requests for files with extension .html to .asp and redirect all .asp requests to .html Example: file_xyz.asp rewrites to file_xyz.html directory1/file_xyz.asp rewrites to directory1/file_xyz.html and file_xyz.html redirects to file_xyz.asp directory1/file_xyz.html redirects to directory1/file_xyz.asp What is the syntax for the rule Is this too broad a rule? If I should need for what ever reason to have a physical file such as file_abc.html how do I exclude it from the redirect rule? I am thinking I should just use ISAPI_Rewrite http://www.isapirewrite.com/ there seems to be a ton of resources out there for rewriting with htaccess and very little online help for using IIS 7 URL rewrite. Any thoughts and/or advice Thanks in advance

  • Help porting a bit of Prototype JavaScript to jQuery

    - by ewall
    I have already implemented some AJAX pagination in my Rails app by using the example code for the will_paginate plugin--which is apparently using Prototype. But if I wanted to switch to using jQuery for future additions, I really don't want to have the Prototype stuff sitting around too (yes, I know it's possible). I haven't written a lick of JavaScript in years, let alone looked into Prototype and jQuery... so I could use some help converting this bit into jQuery-compatible syntax: document.observe("dom:loaded", function() { // the element in which we will observe all clicks and capture // ones originating from pagination links var container = $(document.body) if (container) { var img = new Image img.src = '/images/spinner.gif' function createSpinner() { return new Element('img', { src: img.src, 'class': 'spinner' }) } container.observe('click', function(e) { var el = e.element() if (el.match('.pagination a')) { el.up('.pagination').insert(createSpinner()) new Ajax.Request(el.href, { method: 'get' }) e.stop() } }) } }) Thanks in advance!
