Sxript Programming Language

Abstract

Sxript is an interpreted functional/procedural programming language designed for numerical evaluation and problem solving with high-order functions, variable storage, scoped subprograms, and arbitrary-precision numbers, along with file I/O, graphical output, and more. Sxript may be used as a stand-alone tool on most devices, or included as a component of any BASIC, JavaScript, or C++ application. All source code is written in a strict subset of the QB45 language, and is auto-translated by the BAS-TO-X utility into other languages.

Example Program Discussion Links `...All programs are actually subprograms...': Quotes and Numbers pass through as stable. Lines are separated by the semicolon ( : ). Quote , Number include(`../test/arithmetic.txt'): Execute subprogram stored on file, namely arithmetic.txt. Execute , arithmetic.txt print_`Welcome!\n': Print a welcome message. Note the newline sequence \n before closing the quote. Print let(rollone,dice(6)): Call the dice function to generate a random number from a 6-sided dice, and store the result in variable rollone. Function , Let print_`Single roll: ' + quote([rollone]) + `\n': Print the stored result of single dice roll embedded in a quote. The variable reference is replaced by its literal value when enclosed in square brackets ( [ ] ). Variable Reference func(rolltwo,{<dice([x]),dice([x])>}): Define a single-line function that rolls two [x]-sided dice and returns a vector. func , Vector print_`Your double dice roll is: ' + quote(rolltwo(6)) + `\n\n': Whitespace and break returns only matter within quotes. Whitespace func(rollmany,{ Define a function called rollmany. The body occurs as occulted code. Occult   sub({ Multi-line functions are contained in a subprogram or codeblock. Subprogram / Codeblock     let(a,[x]): Input arguments manifest as [x], [y], [z], etc. ...     let(b,[y]): Variables and functions defined in a subprogram are destroyed as the subprogram closes. Codeblocks preserve variables. ...     do: Elementary statements from imperative programming, namely if, goto, do/loop, etc. are available within any (and limited to the same) given subprogram or codeblock. if , goto , do/loop     print_dice([a]),: The only output carried away by the subprogram or codeblock is what follows print. ...     loop: Re-iterate loop if (internal) iteration count less than b. ...   }) Close subprogram. ... }): End definition of function rollmany. ... print_rollmany(6,10) Call rollmany function to roll 6-sided dice 10 times and print the result. ...
