I'd like to use LLVM lli tool as static library (rename main() to lli() and export it in libLLi.a) - to create rich UI for it. How can i modify it (or use without modifications) in order to intercept stdin? Assume i know how to generate LLVM assembly file (using clang -S -emit-llvm .. -o output.ll ) and how to execute it using lli tool ( lli output.ll ). Common use case: Source code of simple app to be interpreted by lli: #include <iostream> using namespace std; int main() { char name[128]; cout << "type your name: "; cin.getline(name, sizeof(name)); cout << "hi, " << name << endl; return 0; }

While inside the Python Interpreter: What are some ways to learn about the packages I have? >>> man sys File "<stdin>", line 1 man sys ^ SyntaxError: invalid syntax >>> sys --help Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: bad operand type for unary -: '_Helper' Corrected: >>> help(sys) ... Now, how do I see all the packages available to me on my sys.path? And see their subsequent usage and documentation. I know that I can easily download a PDF but all this stuff is already baked in, I'd like to not duplicate files. Thanks! You can look at help("modules")

I'm looking for a .NET library that does a specific task. Say my app has been sent a program (in some script language) and I want my app to run that script. That script could come from an openly hostile individual, but I want to run it anyway. (Like JavaScript in a browser.) var sc = new SecureScript("SomeFileFromAnUnknownPossiblyHostileSource.xyz"); /* Set some event handlers. */ sc.Run(); During the Run call, the script could construct it's own data, mess around with simple data types, do whatever it wants as long the effects are contained within it's own world. If the script attempts to

How can I get python interpreter path in uwsgi process (if I started it with -h parameter)? I tryed to use VIRTUAL_ENV and UWSGI_PYHOME environment variables, but they are empty, I do not know why. Also i tryed to use sys.executable , but it points to uwsgi process path. uWSGI is not a python application (it only calls libpython functions) so the effective executable is the uwsgi binary. If you use virtualenvs you can assume the binary is in venv/bin/python 来源： https://stackoverflow.com/questions/18014122/how-to-get-python-interpreter-path-in-uwsgi-process

I love Eclipse and PyDev because it always has the features I need. This time I'd like to connect PyDev to my interpreter that is already running. My interpreter is embedded in my game application, that's why. If it would make it easier, I can also start the game application from Eclipse. However, I've tried to add my game .exe in the interpreter configuration in PyDev but it cannot be started because the .exe need some .cfg files that are located in the .exe's folder. Ecplise seems to not execute the .exe file in its environment. How could I do it? The main reason for all this is that I want

I'm trying to figure out where to start with this project. Perhaps someone can steer me in the right direction. I am given a small language that I must write an interpreter for. The language consists of either an expression in parentheses: (integer integer operator) or an arithmetic IF statement made up of expressions in the form: IF exp1 exp2 exp3 exp4 where exp2 is returned if exp1 is negative, exp3 is returned if exp1 is zero, and exp4 is returned if exp1 is positive. The operator is either + or x (for addition and multiplication respectively). I have to implement a scanner/parser together,

How are functions stored in a variable? According to MDN In JavaScript, functions are first-class objects, because they can have properties and methods just like any other object. What distinguishes them from other objects is that functions can be called. In brief, they are Function objects. Suppose this scenario, var fn = function () {}; fn.attr = 3; console.log(fn); //prints function() {} console.log(Object.keys(fn)); //prints ["attr"] If a function is an object shouldn't it have keys and value kind where the function is stored in a property and the interpreters don't show that property?
