kandi X-RAY | ivy-lang Summary
Ivy is an extensible, dynamically typed, late binding language intended to be used as an embedded command language. It can also be used stand-alone: it can execute script files from the command line or presents a read-eval-print loop (REPL) to the user if no files are given. Ivy's extensibility is based on the fact that statements are syntactically identical to function calls. Also blocks (surrounded by braces) may be used as function arguments. Thus, new user-defined statements can be added just by defining functions. Function arguments are packaged up as thunks and may have their evaluation delayed and execution environment modified. This allows user defined functions to do many of the things that traditional language statements can do. A number of features make Ivy suitable as a command language. Commands in Ivy are just function calls, but with a convenient lightweight syntax. Also, Ivy supports named arguments, default argument values and variadic functions. Ivy source code is compiled to byte-code which is then interpreted. Ivy's compiler and interpreter are both event driven (meaning that they return to the top level when more input is needed). This allows Ivy to be easily embedded into other programs. Ivy uses garbage collection for memory management.
