Why are there so few C++ interpreters

18 Dec 2023 by pasztorpisti

Quote: I personally know of only 1 C++ interpreter, which is used by Root (CINT, developed at CERN). It made me wonder why there are so few, and the obvious answer is that C++ is a very complex language to parse. No one in their right mind would...

How do you 'design' a byte code?

3 Mar 2016 by OriginalGriff

Don't bother.If you have a system that works, just encrypt the data, and decrypt it into your program when you need it.Depending on the language you wrote the game in, encryption in some form is probably built in, or easily available as a library.The advantage of this is that your strings...

Please see comments to the question, by bling (good idea about C++/CLI), and myself.The fact is: CINT is not a C++ interpreter. CINT is not a C++ interpreter. This is clearly stated here:http://en.wikipedia.org/wiki/CINT[^].The language is some simplified language based on C and...

Why are there so few C++ interpreters

My speculative reason: There seems no one have had the need compared to the efford to do it. I.e. you might be able to build an Eiffel Tower in your garden, assuming you have the space, the material, the people, the good enough ground, etc. and you can do it for your own pleasure. ;-)The...

Why are there so few C++ interpreters

18 Jul 2014 by Manikandan10

Because C++ is a massive programming language. It is just too complicated. Interpreters are created for languages like Python, JavaScript not only that they are simple, but they are meant to be interpreted, they are dynamic. The first Python implementation was an interpreter; not a compiler. Not...

Is this the interpreter?

19 Jan 2013 by OriginalGriff

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.Try it yourself, you may find it...

Why are there so few C++ interpreters

It's hard to really "solve" this question - may have been better in a forum, but here's my 2c.The language definition does not really preclude making an interpreter, but C++ was really designed as a low-level language that can be used for extremely efficient code. The language is extremely...

How do you 'design' a byte code?

3 Mar 2016 by Nafees Hassan

I've been created an interpreter for an scripting engine for my games, and I've created it. But the problem is that I don't want to others to be able to see the code (script), for that, I need to create a compiler that compiles the script to a byte code. But how do you 'design' a byte code? How...

[.net] how the MSIL code is being executed without compilation ?

28 Jul 2017 by The_Unknown_Member

Im wondering how the MSIL is running without being compiled firstly ? As I know .NET uses a JIT compiler and the JIT compiler is both interpreter and compiler which runs after the program start (in run-time). So how the MSIL is getting executed ? What I have tried: Asking a question here in...

Hello, Just a general question: A made-up programming language that is then interpreted/compiled(?) using a high-level programming language such as C++ to give output is what: a compiler or an interpreter E.g. MoveCursor(132, 242 (Spline)) - made up programming language example. This...

How do I set up a loop that parses a string and executes commands with turtlein Python bases on the parsed section of the string

9 Oct 2018 by Richard MacCutchan

If you know the structure of the command then it should be easy to split it into its constituent tokens. You can use substring notation if each part is fixed length or regexes if they are variable. Alternatively you can use string searching to find specific field delineators. Once you have the...

Is it a bad idea to create a parser for an interpreted language using hashed tokens?

Interpreter not outputting characters

24 Aug 2023 by k5054

You're right, you have an infinite loop. When you get to a ']', you go back to the matching '[', and repeat, indefinitely. There's no exit condition, nor is it clear what the exit condition should be. Should the interpreter loop only once? Or...

My input would be "F100S20>60" F100 would move the turtle forward 100, S20 would draw a circle with the radius of 20, and >60 would rotate the turtle. I cant figure out how to move along with the string and get the different commands from each part. What I have tried: I have a function set up...
