newLISP and the O.S. /

Hi Lutz,

Changing to StdCall seems to have fixed it. Thanks.

newLISP and the O.S. / NewLisp.dll and C#

Hi,

I was wondering has anyone tried calling newlispEvalStr from a C# application? Do you have some code to show me how or can you point me in the right direction?

I have tried using dllImport and it seems (i.e. in debug view I can see (+ 2 2) returns "4n") to work but I keep getting AccessViolationExceptions.

Class which import newlisp.dll (NewLispDLL.cs) is:

Code Select Expand

using System;
using System.Text;
using Microsoft.CSharp;
using System.Runtime.InteropServices;

class NewLispDLL
{
    [DllImport("C:\Program Files\newlisp\newLisp.dll", EntryPoint = "newlispEvalStr", CallingConvention = CallingConvention.Cdecl)]
    private static extern System.Text.StringBuilder newlispEvalStr(string txt);

    public static string Eval(string LispExpression)
    {
        System.Text.StringBuilder ResultObject;
        ResultObject = newlispEvalStr(LispExpression);
        return ResultObject.ToString();
    }
}

Code that calls it (Program.cs) is:

Code Select Expand

using System;
using System.Collections.Generic;
using System.Text;

namespace NewLispTest
{
    class Program
    {
        static void Main(string[] args)
        {
            string strCmd = "(+ 2 2)";
            string txt = "";
            txt = NewLispDLL.Eval(strCmd);        
            Console.WriteLine(txt);
            Console.ReadLine();
        }
    }
}

Thanks.

Anything else we might add? /

Thanks Tim. I only use windows at work and I was having the same problem on Mac OS X and Linux at home. I look forward to trying out your next version.

Hi,

Some newbie questions. I have been trying to get Tim's emacs mode to load but I get the following error on startup. Using emacs 21.3 on Windows. I also got this error on Linux.

~~Quote~~
Debugger entered--Lisp error: (error "Invalid escape character syntax")

eval-buffer(#<buffer *load*<2>> nil "nl-docstrings" nil t)

load-with-code-conversion("c:/home/emacs-21.3/lisp/nl-docstrings.el" "nl-docstrings" nil t)

require(nl-docstrings)

eval-buffer(#<buffer *load*> nil "~/.emacs" nil t)

load-with-code-conversion("c:/.emacs" "~/.emacs" t t)

load("~/.emacs" t t)

Anyone any ideas?

I have hacked scheme.el in the mean time and it seems to be working ok.

What I would like to have is a key sequence which would load the current buffers file into a running newLisp instance in another buffer, is this possible?

I would also like to have a key sequnce to show documentation for the function my cursor is currently at.

Has anyone anything like this running that they could share with us newLisp/emacs newbies in the crowd?

Thanks.
