cling's Introduction

Cling - The Interactive C++ Interpreter

The main repository is at https://github.com/root-project/cling

Overview

Cling is an interactive C++ interpreter, built on top of Clang and LLVM compiler infrastructure. Cling implements the read-eval-print loop (REPL) concept, in order to leverage rapid application development. Implemented as a small extension to LLVM and Clang, the interpreter reuses their strengths such as the praised concise and expressive compiler diagnostics.

cling's Issues

Maintain in debian depo?

This is a great learning tool! Any chance it might eventually make it into a debian repo? Or at the very least a ppa?

Thanks!

Tab auto-complete

It would be neat feature if Cling used Clang's auto-completion in the REPL.

Cling not loading Boost

This may be asking too much, but currently Cling does not load Boost headers, and just crashes.

How to configure jupyter-cling-kernel to use std=c++11?

I checked jupyter-cling-kernel --help but I failed to find any command line switch to pass arguments to cling. Can anyone help me?

I am setting up C++ kernel for Jupyter. I want students to be able to use iostream library - but this requires c++11 compatibility, which is not by default.

I use headless Ubuntu 16.04 server.

How this looks on github

Here on github, the "repo description" should be short.

I recommend "Cling is an interactive C++ interpreter, built on top of Clang and LLVM compiler infrastructure."

This page describes how to change it. http://stackoverflow.com/questions/7757751/how-do-you-change-a-repository-description-on-github

Cheers!

cpt should check if subprocess calls fail

Currently, if a make step fails, cpt rather happily tries to keep going. I'm attempting to build a dmg with cling, and it's failing to build cling. Instead of quitting, it keeps going and attempts to build an empty dmg, which breaks in even more surprising ways.

Suggested patch: use check_output and check_call instead of Popen in exec_subprocess_call/exec_subprocess_check_output; the check methods will throw an exception if the called process returned a non-zero exit code. check_output is new to Python 2.7; if compatibility with Python 2.6 is needed, you can use a drop-in replacement like this one.

Replace the LLVM module jit by mcjit

The jit module will be removed and is replaced by mcjit in llvm > 3.5.
I'm trying to build an homebrew formula for cling and I ran into the issue that llvm 3.6.x (provided in homebrew) no longer has the jit module. Instead it has moved to the new mcjit.

Integrating cling into existing application.

Hi there, I got interested in cling due to the fact I would like to integrate cling into my existing game engine, the project is just a learning toy nothing serious, for the time being i need some really basic stuff and I would rather avoid to go down the path of integrating a fully fledged scripting language.
Would it be possible to achieve that result with cling? I tried to have a look at the doc but is a bit overwhelming since is basically class documentation and not really a library documentation on the overall project.
If what I am after is possible (i would assume so), would you be able to point me to the relevant classes needed ?

Please bear with me, I am new to this jit world so If I ask stupid things let me know.

Cheers

failedTemplateInstantiations.C test

@manasij7479 what https://github.com/vgvassilev/cling/commits/master/test/Lookup/failedTemplateInstantiations.C was supposed to test? I saw it was checked in as a part of the old autoloading implementation which is gone now. Does this test make sense with the new implementation of the autoloading? Could it be removed?

Do not print empty namespaces in the forward decl maps

Hi,
[cling$] .T map map_fwd.h
produces declarations such as:

namespace std {                         
}

Those should be omitted, because they are empty.

Meet a bug when encountering errors

Hey, I found something unexpected when I write some wrong codes, like this:

typedef mpl::range_c<int, 0, 10> ran;
typedef mpl::plus<_1, mpl::int_<2> > add2;
/* this line will get some errors when template instantiation */
typedef mpl::transform<ran, add2>::type newran;  
/* but when I type in the same line, there will be no errors. */
typedef mpl::transform<ran, add2>::type newran;

Besides, after the second line, the type "newran" will becomes int.

Maybe you should do something to fix this. Thank you!

Update root ReadMe.md

Hi,
Once we have #29 we should update the build instructions in cling's ReadMe.md

New Error

Hi @vgvassilev,

I have a new error that I never had when I last built a few months ago.

In file included from llvm/tools/cling/lib/Interpreter/ValuePrinter.cpp:10:0: llvm/tools/cling/lib/Interpreter/../../include/cling/Interpreter/Value.h: In instantiation of 'static T cling::Value::CastFwd<T>::cast(const cling::Value&) [with T = long double]': llvm/tools/cling/lib/Interpreter/../../include/cling/Interpreter/Value.h:209:36: required from 'T cling::Value::simplisticCastAs() const [with T = long double]' llvm/tools/cling/lib/Interpreter/ValuePrinter.cpp:213:48: required from here llvm/tools/cling/lib/Interpreter/../../include/cling/Interpreter/Value.h:104:53: error: cast from 'void*' to 'long unsigned int' loses precision [-fpermissive] return (T) (unsigned long) V.getAs<void*>();

Seems like the header is wrong ?

Why is this cast from 'void_' to 'long unsigned int'
include/cling/Interpreter/Value.h:104:53:
return (T) (unsigned long) V.getAs<void_>();

Should this not be size_t and not unsigned long ?

Implement a printStats for the ForwardDeclPrinter

Hi,
We need to implement statistics showing how many decls were omitted, what are the omitted decl kinds and so on.
Vassil

Forward decl printer: bad ordering

class CastorElectronicsMap{
   public:
      class PrecisionItem{};
      typedef PrecisionItem TheTypedef;
};

class A{};
typedef A TheTypedef;

class B{};
namespace ns {
typedef B TheTypedef;
class C{};
}

causes the following forward decls:

extern int __Cling_Autoloading_Map;
class __attribute__((annotate(\"nestedClasses.h\")))  CastorElectronicsMap;
namespace ns {
typedef B TheTypedef __attribute__((annotate(\"nestedClasses.h\"))) ;
class __attribute__((annotate(\"nestedClasses.h\")))  C;
}

This causes the following error:

error: unknown type name 'B'
typedef B TheTypedef __attribute__((annotate("nestedClasses.h"))) ;
        ^

Could this be fixed, please?

Cheers, Axel.

What's the difference between this repo...

and this repo http://root.cern.ch/git/cling.git ?

Cannot make an ofstream

I just tried this

#include <fstream>
#include <iostream>
#include <string>
using namespace std;
ofstream ofs("test.txt");

and Cling gave me a "no matching constructor" error

Complete quoting for parameters of some CMake commands

Some parameters (like "${CLING_SOURCE_DIR}/lib/" and "${CMAKE_CURRENT_BINARY_DIR}/cling-compiledata.h") are passed to CMake commands in your build scripts without enclosing them by quotation marks. I see that these places will result in build difficulties if the contents of the used variables will contain special characters like semicolons.

I would recommend to apply advices from a wiki article.

Enumerate incompatibility issues in cpt run with python 2.7 and 3.4

Hi Ani,
Could you enumerate cpt issues if we want to upgrade it to python 3.4. I tested with 3.4 and there were some incompatibilities.
Here I found some more info https://docs.python.org/3/howto/pyporting.html If those issues are tiny we even could implement them in a version independent way see section "Writing Source-Compatible Python 2/3 Code"

How to modify

Hi I created my own programming language with flex and bison, now how can i put this in your interpreter? Thanks in advanced

Build process (as described in README.md) not working

Hi,

I'm trying to build cling from source using exactly the method
you described in the README.md of this repository. I'd rather
like to download ready-to-play binaries, but I read, that's not
possible right now because of your infrastructure refactoring.

I also tried to build the package using this build script that is linked also in the
documentation. No success either. CMake threw a very
strange error claiming that a "SetTheory" Module might be
missing or simply corrupt(?). Then I tried to use onyb's
uploaded binaries, but since they've been build specifically for Ubuntu, I can't
run them, because I'm currently running Arch.

My CMake version is 3.4.3

Am I missing an obvious step?
Could you update your build instructions?

Does cpt ask whether or not to still package if the test suite fails?

Create and use a PCH/PCM

We should create a PCH/PCM at startup of the headers in the system include paths.

Interactive interpreter does not exit on EOF

On linux, when you're on a terminal, you can use Ctrl+D to send EOF to the program.

For example, in python, typing Ctrl+D in the terminal exits the interpreter.

The following snippet also exists on EOF.

#include <iostream>
#include <string>

int main(int argc, char *argv[])
{
    std::string str;

    while (std::getline(std::cin, str))
        std::cout << "You typed : " << str << std::endl;

    return 0;
}

Is there a reason why cling ignores my Ctrl+D ?

Hook in cpt build package also in cling's build system.

Making use of the compilation database

Many thanks for a very useful project. This is more of a question than a issue. Does Cling support the compilation database? It would be great if one could load up a compilation database for a given project, and then be able to include any of the files on that project and use them from cling.

The path https://ecsft.cern.ch/dist/cling/ is invalid

Seems like the binary download location moved somewhere; can no longer download binaries pointed to from the ROOT Cling page :(

Binary snapshots 404

The link https://ecsft.cern.ch/dist/cling given in README.md seems to be down?

Cleanup for running threads

Code:
[cling]$ #include
[cling]$ auto f = [] () {while(1);};
[cling]$ std::thread t(f);
[cling]$ .q
terminate called without an active exception
Aborted (core dumped)

This can be considered reasonable behaviour for a compiler.
But since cling is an interactive environment, I think it should handle active threads in some special manner at exit.

Example use case:
In my code the thread is a display window.
I would prefer if the user could exit with the .q meta command instead of closing the window separately.

Any idea where to look for this?
Standard C++ doesn't allow terminating threads manually, afaik.

Clearing Cling Shell

I have a doubt about clearing the window of Cling. I used Ctrl+L on my Linux machine but it didn't worked.

Is there other commands like ".q" in Cling shell ?? How can I get the list of commands in shell ??

Also is there any way to clear the variables ??

int a = 23;

#include<string>
string a = "Something";

Improve exception safety with smart pointers

Would you like to wrap any pointer data members with the template class "std::unique_ptr"?

Update candidates:

The binary snapshot download page (https://ecsft.cern.ch/dist/cling) is broken.

The SSL certificate is invalid (domains don't match) and even if this error is ignored the server returns 404 not found.

#include<iostream> causes: !DD && Handlers.empty() && "Debug/EH info didn't get finalized"

I've successfully built cling on Windows7 with cmake & vs2013. While I was trying to include some cpp headers, the following error occurred:

[cling]$ .L iostream
Assertion failed: !DD && Handlers.empty() && "Debug/EH info didn't get finalized", fi
le E:\ABOUT-C++\cling\src\lib\CodeGen\AsmPrinter\AsmPrinter.cpp, line 113

Am I doing it the wrong way? Or it's a bug of cling with Windows?

Completion of error handling

I have looked at a few source files for your current software. I have noticed that some checks for return codes are missing.

Would you like to add more error handling for return values from functions like the following?

fflush ⇒ FILEPrintHelper::Print
signal ⇒ TerminalConfigUnix constructor

Forward decl maps lose information about the inclusion point

Hi,
[cling$] .T map map_fwd.h
produces output like:

  typedef unsigned long __fsfilcnt64_t __attribute__((annotate(""))) ;

i.e the information about the inclusion point is missing.
