2E Programming Language

2E Programming Language is a simple algebraic syntax language that natively supports expressions and function definitions. It has very minimalistic features, which makes it quite easy to learn if you are already familiar with general programming constructs. The language is referred to as 2e, but the interpreter is called ee. Operands can be literals like numeric values, quoted strings, single-quoted characters, variables, or function calls. Meanwhile, operators consist of standard algebraic operators, assignment, logical operators, sub-expression join operator, and a conditional operator pair like in C. Additionally, it has an iterative conditional pair.

When called with the "-p" flag, ee evaluates the next parameter and prints the final result. The "-c" flag does the same but doesn't print the final result, which is useful when the expression already contains output statements. The ";" operator is not necessarily a statement terminator but is a join operator. It evaluates the left and right expressions and returns the result of the right-hand side. It has the lowest order of precedence, making it work similarly to a statement terminator.

The "?" conditional operator checks if the "expr_test" is true. If it is, then "expr_true" is evaluated and returned; otherwise, "expr_false" is evaluated and returned. Similarly, the iterative conditional operator checks if "expr_test" is true, repeatedly evaluates "expr_true", and returns its final value when "expr_test" is false. Nevertheless, if "expr_test" is never true, only then is "expr_false" evaluated and returned.

In cases where an operator of lower precedence than "?" or "??" is encountered, the default false target is automatically assumed. This means that both "result = expr_test ? expr_true : 0;" and "result = expr_test ? expr_true;" are the same. A more extensive example using the 2E Programming Language shows how to use multiple operands, including arrays. The example also uses the interpreter using the Unix "#!" syntax.

Overall, 2E Programming Language (ee) is an excellent option for those looking for a simple, algebraic syntax language that supports expressions and function definitions. In conclusion, it may take time to fully understand how the different operators work, but once learned, it can be a productive tool.
