A C-like, interpretive, {object-oriented
programming} language, class library, and integrated
development environment designed specifically for development
of application programs for Microsoft Windows and {Windows
NT}. Designed by Jack Krupansky of
Base Technology, Liana was first released as a commercial
product in August 1991. The language is designed to be as
easy to use as BASIC, as concise as C, and as flexible as
Smalltalk.
The OOP syntax of C++ was chosen over the less familiar
syntax of Smalltalk and Objective-C to appeal to C
programmers and in recognition of C++ being the leading OOP
language. The syntax is a simplified subset of C/C++. The
semantics are also a simplified subset of C/C++, but
extended to achieve the flexibility of Smalltalk.
Liana is a typeless language (like Lisp, Snobol and
Smalltalk), which means that the datatypes of variables,
function parameters, and function return values are not needed
since values carry the type information. Hence, variables are
simply containers for values and function parameters are
simply pipes through which any type of value can flow.
Single inheritance, but not multiple inheritance, is
supported. Memory management is automatic using {reference
counting}.
The library includes over 150 classes, for dynamic arrays,
associative lookup tables, windows, menus, dialogs,
controls, bitmaps, cursors, icons, mouse movement, keyboard
input, fonts, text and graphics display, DDE, and MDI.
Liana provides flexible OOP support for Windows programming.
For example, a list box automatically fills itself from an
associated object. That object is not some sort of special
object, but is merely any object that "behaves like" an array
(i.e., has a "size" member function that returns the number of
elements, a "get" function that returns the ith element, and
the text for each element is returned by calling the "text"
member function for the element).
A related product, C-odeScript, is an embeddable application
scripting language. It is an implementation of Liana which
can be called from C/C++ applications to dynamically evaluate
expressions and statement sequences. This can be used to
offer the end-user a macro/scripting capability or to allow
the C/C++ application to be customized without changing the
C/C++ source code.
Here's a complete Liana program which illustrates the
flexibility of the language semantics and the power of the
class library:
main
{
// Prompt user for a string.
// No declaration needed for "x" (becomes a global variable.)
x = ask ("Enter a String");
// Use "+" operator to concatenate strings. Memory
// management for string temporaries is automatic. The
// "message" function displays a Windows message box.
message ("You entered: " + x);
// Now x will take on a different type. The "ask_number"
// function will return a "real" if the user's input
// contains a decimal point or an "int" if no decimal
// point.
x = ask_number ("Enter a Number");
// The "+" operator with a string operand will
// automatically convert the other operand to a string.
message ("You entered: " + x);
// Prompt user for a Liana expression. Store it in a
// local variable (the type, string, is merely for
// documentation.)
string expr = ask ("Enter an Expression");
// Evaluate the expression. The return value of "eval"
// could be any type. The "source_format" member function
// converts any value to its source format (e.g., add
// quotes for a string.) The "class_name" member function
// return the name of the class of an object/value.
// Empty parens can be left off for member function calls.
x = eval (expr);
message ("The value of " + expr + " is " + x.source_format +
" its type is " + x.class_name);
}
The author explained that the "Li" of Liana stands for
"Language interpreter" and liana are vines that grow up trees
in tropical forests, which seemed quite appropriate for a tool
to deal with the complexity of MS Windows! It is also a
woman's name.
