Very Computer

Hello,

I want to embed a C (maybe a "slim" version) interpreter into my
software.  It should by easily extensible to add some software (MS
VC++ MFC) specific routines.

I search the web for source codes, but all codes are found are very
complex and I don't know how to embed them correctly. I hoped to find
a single class which contains all...  Can anyone help me?

would be useful. -John]

Hi Marco,
a C interpreter in "a single class"?
This is a complex piece of code and can definitly not been
handled by a single class.
Only if you use a activex script engine, you need to implement
a script host. This can be done with a single class.
There is a scriptengine called debugscript (as a sample how to
implement a script engine with a debug interface). I remember
it as running a C-style language.
Regards,
Juergen

XC*was the name of an old editor for X Windows which had a
SMall ANSI C interpreter (SMAC) embedded. I suppose it was
not a complex interpreter. XC*is now at

for a User's Manual with examples. There's also EiC,

but I'm afraid it is not very simple.

Good luck.

You can take a look at Ch - a C interpreter supporting C++ class.
It is also embeddable and extendable with Ch SDK. You may not
even need to look at the source code for your embedding task.

If C is not essential, then have a look at Guile , (GNU's Ubiquitous
Intelligent Language for Extension)

"Guile is a library designed to help programmers create flexible
applications. Using guile in an application allows programmers to
write plug-ins, or modules (there are many names, but the concept is
essentially the same) and users to use them to have an application fit
their needs.

There is a long list of proven applications that employ extension
languages. Successful and long-lived examples in the free software
world are GNU Emacs and The GIMP.

Very popular examples of extending server applications are the apache
projects perl and php modules.

Extension languages allow users, programmers, and third-party
developers to add features to a program without having to re-write the
program as a whole, and it allows people extending a program to co-
operate with each other, without having to expend any extra effort.

Guile is a programming language.  Guile is an interpreter packaged as
a library which can be incorperated into your programs. Your users
have full access to the interpreter, so guile itself can be extended,
based on the needs of the user. The result is a scripting language
tailored to your application."

[If you don't need C, there's a bunch of other extension languages that
are widely used such as python, TCL, REXX, and Lua. -John]
