  • How to set UCS2 in numpy?

    - by mindcorrosive
    I'm trying to build numpy 1.2.1 as a module for a third-party python interpreter (custom-built, py2.4 linux x86_64) so that I can make calls to numpy from within it. Let's call this one interpreter A. The thing is, the system-wide python interpreter (also py2.4, let's call it B) from the vendor is built with --enable-unicode=ucs4, while the custom one is with UCS2. Needless to say, when I try to build a module with B, I get an error when I try to import numpy in A -- it complains about undefined symbol _PyUnicodeUCS4_IsWhiteSpace. I've searched around and apparently there's no way around this but to compile a custom Python interpreter -- which I did (let's call it interpreter C), properly specifying the unicode string length (verifiable through sys.maxunicode). I managed to build numpy with C as well, surprisingly enough, but still the problem persists when I try to import it in interpreter C. Previously, when I built numpy using B, there were no problems when importing it in B, but A would complain. Perhaps there's an option when building numpy to specify the length of Unicode strings to be used, as when configuring Python builds? Or am I doing something else wrong? A few notes: Upgrading to newer versions of python and/or numpy is not an option - interpreter A will stay on this version of the grammar for the foreseeable future. Also, it is not possible to start the interpreter A in standalone mode to build numpy with it, as it needs some other libraries preloaded I know that this whole thing is a mess, but I'd appreciate any help I can get to make this work. If you need more information, please let me know, I'd be happy to oblige. Thanks to everybody for their time in advance.

  • Can I strictly evaluate a boolean expression stored as a string in Java?

    - by D Lawson
    I would like to be able to evaluate an boolean expression stored as a string, like the following: "hello" == "goodbye" && 100 < 101 I know that there are tons of questions like this on SO already, but I'm asking this one because I've tried the most common answer to this question, BeanShell, and it allows for the evaluation of statements like this one "hello" == 100 with no trouble at all. Does anyone know of a FOSS parser that throws errors for things like operand mismatch? Or is there a setting in BeanShell that will help me out? I've already tried Interpreter.setStrictJava(true). Here's the code that I'm using currently: Interpreter interpreter = new Interpreter(); interpreter.setStrictJava(true); String testableCondition = "100 == \"hello\""; try { interpreter.eval("boolean result = ("+ testableCondition + ")"); System.out.println("result: "+interpreter.get("result")); if(interpreter.get("result") == null){ throw new ValidationFailure("Result was null"); } } catch (EvalError e) { e.printStackTrace(); throw new ValidationFailure("Eval error while parsing the condition"); }

  • Problems with tk85.dll when shutting down an application that embeds the Python interpreter.

    - by George Edison
    My C++ application embeds the Python interpreter, but seems to be having some trouble when it shuts down. Right after the main window closes, I get a segmentation fault (this is Windows, but we'll call it a segmentation fault anyway). The stack trace is below: #0 102AD580 tk85!Tk_MainWindow() (C:\Users\Nathan\Documents\Projects\PowerPad 1.3\bin\Debug\lib\tk85.dll:??) #1 103082DD tk85!XSetStipple() (C:\Users\Nathan\Documents\Projects\PowerPad 1.3\bin\Debug\lib\tk85.dll:??) #2 102214A3 ??() (C:\Users\Nathan\Documents\Projects\PowerPad 1.3\bin\Debug\lib\tk85.dll:??) #3 10220000 ??() (??:??) #4 00000000 ??() (??:??) Where would I even begin to debug this problem?

  • How can I deploy a Perl/Python/Ruby script without installing an interpreter?

    - by Brian G
    I want to write a piece of software which is essentially a regex data scrubber. I am going to take a contact list in CSV and remove all non-word characters and such from the person's name. This project has Perl written all over it but my client base is largely non-technical and installing Perl on Windows would not be worth it for them. Any ideas on how I can use a Perl/Python/Ruby type language without all the headaches of getting the interpreter on their computer? Thought about web for a second but it would not work for business reasons.

  • Are there any free embedable REPL interpreters for a website? [migrated]

    - by Google
    I am hoping to find a free REPL interpreter for a number of languages. I am starting a new web page to help developers learn with a number of tutorials. I want to embed an interpreter on the site so users can have a tutorial and interpreter side by side. I really like free interpreters such as the one at repl.it. However, I am unable to find a free/embeddable interpreter. I was hoping to avoid making one myself-- they seem tricky to make safely! Thanks!

  • Does the Python 3 interpreter have a JIT feature?

    - by guz
    I found that when I ask something more to Python, python doesn't use my machine resource at 100% and it's not really fast, it's fast if compared to many other interpreted languages, but when compared to compiled languages i think that the difference is really remarkable. It's possible to speedup things with a JIT compiler in Python 3 ? Usually a JIT compiler is the only thing that can improve performances in interpreted languages, so i'm referring to this one, if other solutions are available i would love to accept new answers.

  • How to compile scheme into native binary files ?

    - by Joe
    I am very new to scheme. And now I am trying to compile some scheme code into binary file which will be loaded faster into interpreter. (The interpreter is a hybrid interpreter)Some one told me that I can compile the code into native binary file and then load it into interperter. And my question is: 1. What is the native binary file? 2. How can I compile the scheme code into a native binary file? 3. How can I load native bianry file into scheme interpreter? Thanks in advance. Joe Suggested that I want to compile below code into native binary file: (define test (lambda() (display "this is a test")) And then load the bianry file into interpreter and call the function "test".

  • java.lang.ClassNotFoundException in Netbeans. 5 hours to fix

    - by user1304281
    Hi I've got to submit an interpreter assignment tonight and all of a sudden it stopped working! It was working yesterday but now when I try to create a class instance at runtime I get classnotfoundexception. My project has no libraries or dependencies, I've written everything myself. I've googled around and it seems to be an issue with classpath but I've had no luck fooling with the project properties on netbeans. Here's some code: package interpreter; import interpreter.bytecode.ByteCode; import java.io.*; import java.lang.reflect.*; class ByteCodeLoader { //.... String codeClass = CodeTable.CodeTable.get(args[0]); ByteCode bytecode = (ByteCode)(Class.forName("interpreter.bytecode."+codeClass).newInstance()); //this throws exception } all of my ByteCodes are contained within a subpackage of interpreter called interpreter.bytecode. I'll be watching this thread so I can answer/clarify any questions immediately. Thanks for your time!

  • How do I create a custom python interpreter? i.e. with certain modules already included?

    - by Johnny Brown
    If you've used Ruby on Rails, I'm thinking of the feature where the user types 'rails console' and instantly gets a Ruby console with rails and the current app already loaded. I want to make something like this for a python program I'm working on, does anyone know how I would get to type say, 'python myPythonConsole.py' and open up a regular python interpreter but with my program and all its dependencies loaded?

  • What exactly interpret #!/bin/bash line?

    - by vava
    Many scripts in different languages have a #!/bin/bash header with a path to interpreter, so they can be executed without explicit call to interpreter from command line. But what exactly reads this line and run the interpreter, is it shell or kernel?

  • What is the equivalent word for "compile" in an interpreted language?

    - by user46874
    (I was encouraged to ask this question here.) In C, we say: GCC compiles foo.c. For interpreters (such as Lua), what is the equivalent verb? The Lua interpreter ____ foo.lua. When I write instructions for users of my Lua script, I often say: Run the interpreter on foo.lua. I think this can be said more succinctly: Interpret (or Translate) foo.lua. but that sounds awkward for some reason (perhaps because I'm unsure of its correctness). I can't really say compile because users may confuse it with the usage of the Lua compiler when I actually mean the Lua interpreter.

  • Make mod_wsgi use python2.7.2 instead of python2.6?

    - by guron
    i am running Ubuntu 10.04.1 LTS and it came pre-packed with python2.6 but i need to replace it with python2.7.2. (The reason is simple, 2.7 has a lot of features backported from 3 ) i had installed python2.7.2 using ./configure make make altinstall the altinstall option installed it, without touching the system default version, to /usr/local/lib/python2.7 and placed the interpreter in /usr/local/bin/python2.7 Then to help mod_wsgi find python2.7 i added the following to /etc/apache2/sites-available/wsgisite WSGIPythonHome /usr/local i start apache and run a test wsgi app BUT i am greeted by python 2.6.5 and not Python2.7 Later i replaced the default python simlink to point to python 2.7 ln -f /usr/local/bin/python2.7 /usr/bin/python Now typing 'python' on the console opens python2.7 but somehow mod_wsgi still picks up python2.6 Next i tried, PATH=/usr/local/bin:$PATH export PATH then do a quick restart apache, but yet again its python2.6 !!

  • Requiring multithreading/concurrency for implementation of scripting language

    - by Ricky Stewart
    Here's the deal: I'm looking at designing my own scripting/interpreted language for fun. I'm only in the planning stages right now; I want to make sure I have a very strong hold on exactly how I will implement everything before I start coding. What I'm currently struggling with is concurrency. It seems to me like an easy way to avoid the unpredictable performance that comes with garbage collection would be to put the garbage collector in its own thread, and have it run concurrently with the interpreter itself. (To be clear, I don't plan to allow the scripts to be multithreaded themselves; I would simply put a garbage collector to work in a different thread than the interpreter.) This doesn't seem to be a common strategy for many popular scripting languages, probably for portability reasons; I would probably write the interpreter in the UNIX/POSIX threading framework initially and then port it to other platforms (Windows, etc.) if need be. Does anyone have any thoughts in this issue? Would whatever gains I receive by exploiting concurrency be nullified by the portability issues that will inevitably arise? (On that note, am I really correct in my assumption that I would experience great performance gains with a concurrent garbage collector?) Should I move forward with this strategy or step away from it?

  • What are my choices for server side sandboxed scripting?

    - by alfa64
    I'm building a public website where users share data and scripts to run over some data. The scripts are run serverside in some sort of sandbox without other interaction this cycle: my Perl program reads from a database a User made script, adds the data to be processed into the script ( ie: a JSON document) then calls the interpreter, it returns the response( a JSON document or plain text), i save it to the database with my perl script. The script should be able to have some access to built in functions added to the scripting language by myself, but nothing more. So i've stumbled upon node.js as a javascript interpreter, and and hour or so ago with Google's V8(does v8 makes sense for this kind of thing?). CoffeeScript also came to my mind, since it looks nice and it's still Javascript. I think javascript is widespread enough and more "sandboxeable" since it doesn't have OS calls or anything remotely insecure ( i think ). by the way, i'm writing the system on Perl and Php for the front end. To improve the question: I'm choosing Javascript because i think is secure and simple enough to implement with node.js, but what other alternatives are for achieving this kind of task? Lua? Python? I just can't find information on how to run a sandboxed interpreter in a proper way.

  • Ruby: Does it make sense to use REE with Unicorn?

    - by Miko
    I am trying to figure out the optimal server stack for running Rails. As of now, nginx + unicorn seems to be the best approach. However, some folks have suggested running the REE interpreter instead of Ruby plain. Would nginx + unicorn + REE be the most powerful combination, or will plain interpreter suffice?
