  • Python regular expressions assigning to named groups

    - by None
    When you use variables (is that the correct word?) in python regular expressions like this: "blah (?P\w+)" ("value" would be the variable), how could you make the variable's value be the text after "blah " to the end of the line or to a certain character not paying any attention to the actual content of the variable. For example, this is pseudo-code for what I want: >>> import re >>> p = re.compile("say (?P<value>continue_until_text_after_assignment_is_recognized) endsay") >>> m = p.match("say Hello hi yo endsay") >>> m.group('value') 'Hello hi yo' Note: The title is probably not understandable. That is because I didn't know how to say it. Sorry if I caused any confusion.

  • Python named print?

    - by Mark
    I know it's a really simple question, but I have no idea how to google it. how can I do print '<a href="%s">%s</a>' % (my_url) So that my_url is used twice? I assume I have to "name" the %s and then use a dict in the params, but I'm not sure of the proper syntax? just FYI, I'm aware I can just use my_url twice in the params, but that's not the point :)

Without beeing replaces. ..\ +---soq-business +---soq-layout ..\ +---${artifactIdKey}-business +---${artifactIdKey}-layout How can i achieve this? And how can i place files below soq-business? Without knowing the folder name at this time?

  • How should platform specific lib files be named?

    - by Scott Langham
    Hello, I'm working on a C++ project that produces a lib that other teams use. It's being produced in a few different flavours: Win32 Debug Win32 Debug Static Win32 Release Win32 Release Static x64 Debug x64 Debug Static x64 Release x64 Release Static I'm wondering what the best wisdom is on how to name the dlls and what arguments are for different naming conventions. Do I output the libs into different directories, or do I append some letters on the end of the lib to differentiate them, or something else? One concern is that if I use directories, but don't give all the libs different names, users of the library will have problems where they accidentally use the wrong lib. Are these concerns valid? Thanks very much.

  • Debugging stack data not assigned to a named variable

    - by gibbss
    Is there a way to view stack elements like un-assigned return values or exceptions that not assigned to a local variable? (e.g. throw new ...) For example, suppose I have code along the lines of: public String foo(InputStream in) throws IOException { NastyObj obj = null; try { obj = new NastyObj(in); return (obj.read()); } finally { if (obj != null) obj.close(); } } Is there any way to view the return or exception value without stepping to a higher level frame where it is assigned? This is particularly relevant with exceptions because you often have to step back up through a number of frames to find an actual handler. I usually use the Eclipse debugging environment, but any answer is appreciated. Also, if this cannot be done, can you explain why? (JVM, JPDA limitation?)

  • Perl - how to get the number of elements in a list (not a named array)

    - by NXT
    Hi Everyone, I'm trying to get a block of code down to one line. I need a way to get the number of items in a list. My code currently looks like this: # Include the lib directory several levels up from this directory my @ary = split('/', $Bin); my @ary = @ary[0 .. $#ary-4]; my $res = join '/',@ary; lib->import($res.'/lib'); That's great but I'd like to make that one line, something like this: lib->import( join('/', ((split('/', $Bin)) [0 .. $#ary-4])) ); But of course the syntax $#ary is meaningless in the above line. Is there equivalent way to get the number of elements in an anonymous list? Thanks! PS: The reason for consolidating this is that it will be in the header of a bunch of perl scripts that are ancillary to the main application, and I want this little incantation to be more cut & paste proof.

  • How to pass initialisation parameters to a web service in Netbeans

    - by Bob Roberts
    I have built a web web service with Netbeans 6.8 using the "Web Service from WSDL" wizard. It has generated the binding classes and a skeleton for the class implementing the web service. I've set some initialization parameters in web.xml, under the servlet corresponding to the web service. Now I'd like to pass those parameters to the class implementing the web service. How can this be achieved (preferably without editing any of the code auto-generated by Netbeans)?

  • Problem passing a reference as a named parameter to a variadic function

    - by Michael Mrozek
    I'm having problems in Visual Studio 2003 with the following: void foo(const char*& str, ...) { va_list args; va_start(args, str); const char* foo; while((foo = va_arg(args, const char*)) != NULL) { printf("%s\n", foo); } } When I call it: const char* one = "one"; foo(one, "two", "three", NULL); I get: Access violation reading location 0xcccccccc on the printf() line -- va_arg() returned 0xcccccccc. I finally discovered it's the first parameter being a reference that breaks it -- if I make it a normal char* everything is fine. It doesn't seem to matter what the type is; being a reference causes it to fail at runtime. Is this a known problem with VS2003, or is there some way in which that's legal behavior? It doesn't happen in GCC; I haven't tested with newer Visual Studios to see if the behavior goes away

  • How to copy subdirectories of multiple un-named directories

    - by Scrubbie
    Using just Ant, I want to copy subdirectories of some top-level directories but the names of top-level directories can change so I need Ant to programatically determine which directories to copy. In other words, given the sample directory structure below, copy the contents of each ./<projectX>/bin directory to ./bin. bin project1 \-- bin \-- com \-- name \-- dir1 \-- file1.class \-- file2.class \-- file3.class \-- dir2 \-- file4.class \-- file5.class project2 \-- bin \-- com \-- name \-- dir3 \-- file6.class \-- file7.class \-- file8.class project3 \-- bin \-- com \-- name \-- dir4 \-- file9.class \-- dir5 \-- file10.class \-- file11.class And the end result would be a bin directory that looks like this: bin \-- com \-- name \-- dir1 \-- file1.class \-- file2.class \-- file3.class \-- dir2 \-- file4.class \-- file5.class \-- dir3 \-- file6.class \-- file7.class \-- file8.class \-- dir4 \-- file9.class \-- dir5 \-- file10.class \-- file11.class I've tried <copy todir="${basedir}/bin"> <fileset dir="${basedir}"> <include name="**/bin/*"/> <exclude name="bin"/> </fileset> </copy> but that includes the projectX/bin directories underneath the top-level bin directory.

  • Modifying text files and executing programs with command line parameters in c# or c++ on Linux

    - by Robert Harvey
    I have a need to create a utility in Suze Linux. The utility will make modifications to some text files, and then use the information in those text files to program a device in the computer using a different executable which accepts command line parameters. I am fluent in c#, but have never worked with Linux. Should I take the time to learn Gnu C++ to do this, or install Mono? How would I execute the programming utility and pass it command line parameters?

  • Parameters in ClickOnce

    - by Kyle Rozendo
    Is it possible in any possible way to add to/change the .application file (or any other way) of a ClickOnce deploy file to allow parameters to be specified without the need for the parameters to be passed via the URL? The assembly can be compiled at run time/resigned/etc, or stated otherwise, I am not worried about the bounds of "what else" I would have to do.

  • one codeigniter controller named site needs to handle multiple domains

    - by Mauricio Webtailor
    Got a controller in codeigniter who handles different sub sites. site/index/1 fetches content for subsite a site/index/2 fetches content for subsite b Now we decided to register domain names for these sub sites. so what we need: http://www.subsite1.com - default controller should be site/index/1 without the site/index/1 in the uri http://www.subsite2.com - default controller should be site/index/2 without the site/index/2 in the uri I fiddled and tried to play with routes.php but getting nowhere.. Can somebody point me in the right direction?

  • Pointcut matching methods with annotated parameters

    - by Sinuhe
    I need to create an aspect with a pointcut matching a method if: - Is public - Its class is annotated with @Controller - One of its parameters (can have many) is annotated with @MyParamAnnotation. I think the first two conditions are easy, but I don't know if its possible to accomplish the third with Spring. If it is not, maybe I can change it into: - One of its parameters is an instance of type com.me.MyType (or implements some interface) Do you think it's possible to achieve this? And will performance be good? Thanks

  • Passing dynamic parameters to a stored procedure in SQL Server 2008

    - by themhz
    I have this procedure that executes another procedure passed by a parameter and its parameters datefrom and dateto. CREATE procedure [dbo].[execute_proc] @procs varchar(200), @pdatefrom date, @pdateto date as exec @procs @datefrom=@pdatefrom,@dateto=@pdateto But I need to also pass the parameters dynamically without the need to edit them in the procedure. For example, what I am imagining is something like this CREATE procedure [dbo].[execute_proc] @procs varchar(200), @params varchar(max) as exec @procs @params where @params is a string like @param1=1,@param2='somethingelse' Is there a way to do this?

  • Vim, how to scroll to bottom of a named buffer

    - by Gavin Black
    I have a vim-script which splits output to a new window, using the following command: below split +view foo I've been trying to find a way from an arbitrary buffer to scroll to the bottom of foo, or a setting to keep it defaulted to showing the bottom lines of the buffer. I'm doing most of this inside of a python block of vim script. So I have something like: python << endpython import vim import time import thread import sys def myfunction(string,sleeptime,*args): outpWindow = vim.current.window while 1: outpWindow.buffer.append("BAR") #vim.command("SCROLL TO BOTTOM OF foo") time.sleep(sleeptime) #sleep for a specified amount of time. vim.command('below split +view foo') thread.start_new_thread(myfunction,("Thread No:1",2)) endpython And need to find something to put in for vim.command("SCROLL TO BOTTOM of foo") line

  • Is order of parameters for database Command object really important?

    - by nawfal
    I was debugging a database operation code and I found that proper UPDATE was never happening though the code never failed as such. This is the code: condb.Open(); OleDbCommand dbcom = new OleDbCommand("UPDATE Word SET word=?,sentence=?,mp3=? WHERE id=? AND exercise_id=?", condb); dbcom.Parameters.AddWithValue("id", wd.ID); dbcom.Parameters.AddWithValue("exercise_id", wd.ExID); dbcom.Parameters.AddWithValue("word", wd.Name); dbcom.Parameters.AddWithValue("sentence", wd.Sentence); dbcom.Parameters.AddWithValue("mp3", wd.Mp3); But after some tweaking this worked: condb.Open(); OleDbCommand dbcom = new OleDbCommand("UPDATE Word SET word=?,sentence=?,mp3=? WHERE id=? AND exercise_id=?", condb); dbcom.Parameters.AddWithValue("word", wd.Name); dbcom.Parameters.AddWithValue("sentence", wd.Sentence); dbcom.Parameters.AddWithValue("mp3", wd.Mp3); dbcom.Parameters.AddWithValue("id", wd.ID); dbcom.Parameters.AddWithValue("exercise_id", wd.ExID); Why is it so important that the parameters in WHERE clause has to be given the last in case of OleDb connection? Having worked with MySQL previously, I could (and usually do) write parameters of WHERE clause first because that's more logical to me. Is parameter order important when querying database in general? Some performance concern or something? Is there a specific order to be maintained in case of other databases like DB2, Sqlite etc? Update: I got rid of ? and included proper names with and without @. The order is really important. In both cases only when WHERE clause parameters was mentioned last, actual update happened. To make matter worse, in complex queries, its hard to know ourselves which order is Access expecting, and in all situations where order is changed, the query doesnt do its intended duty with no warning/error!!

  • XmlSerializer construction with same named extra types

    - by NoizWaves
    Hey, I am hitting trouble constructing an XmlSerializer where the extra types contains types with the same Name (but unique Fullname). Below is an example that illustrated my scenario. Type definitions in external assembly I cannot manipulate: public static class Wheel { public enum Status { Stopped, Spinning } } public static class Engine { public enum Status { Idle, Full } } Class I have written and have control over: public class Car { public Wheel.Status WheelStatus; public Engine.Status EngineStatus; public static string Serialize(Car car) { var xs = new XmlSerializer(typeof(Car), new[] {typeof(Wheel.Status),typeof(Engine.Status)}); var output = new StringBuilder(); using (var sw = new StringWriter(output)) xs.Serialize(sw, car); return output.ToString(); } } The XmlSerializer constructor throws a System.InvalidOperationException with Message "There was an error reflecting type 'Engine.Status'" This exception has an InnerException of type System.InvalidOperationException and with Message "Types 'Wheel.Status' and 'Engine.Status' both use the XML type name, 'Status', from namespace ''. Use XML attributes to specify a unique XML name and/or namespace for the type." Given that I am unable to alter the enum types, how can I construct an XmlSerializer that will serialize Car successfully?

  • Method parameters confusion

    - by elec
    Often time methods take more than 3 parameters which are all of the same type, eg. void mymethod (String param1, String param2, String param3) then it's very easy for the client to mix up the parameters orders, for instance inverting param1 and param2: mymethod (param2, param1, param3); ...which can be the cause of much time spent debugging what should be a trivial matter. Any tips on how to avoid this sort of mistake (apart from unit tests) ?
