The OpenScad Useful Library This file offers a set of functions for vector, string, and number operations. Author: Nathanael Jourdane Email: nathanael@jourdane.net Date: December 30, 2015 License: Creative Commons CC-BY (Attribution) thingiverse: http://www.thingiverse.com/thing:1237203 Requires OpenScad 2015.03 or above. Implementing recursive functions is a pleasure for me. If you require a generic function not found in OpenScad, or if you find an error in these ones, feel free to inquire. Another string library: http://www.thingiverse.com/thing:526023 Instructions Copy-paste the function(s) you need from TOUL.scad into your .scad file; OR: Place TOUL.scad in your local OpenSCAD folder under /libraries. On Windows, this folder should default to Documents/OpenSCAD/libraries. Then import TOUL.scad with the following line of code: include "TOUL.scad" [new_vector] new_vector(length, [value]): Returns a vector with length elements initialized to the value. Arguments [int] length: The length of the vector. [char] value (optional): The initial value of the vector. [splittt] split(string, [separator]): Returns a list of substrings by splitting the input string at each occurrence of the separator. Arguments [str] string: The original string. [char] separator (optional): The separator to split the string by (space by default). [stvv] str2vec(string): Returns a list of characters representing the input string. Arguments [str] string: The input string. [subsstt] substr(string, [start], [length]): Returns a substring from the original string. Arguments [str] string: The original string. [int] start (optional): The starting position of the substring (0 by default). [int] length (optional): The length of the substring (default is string length). [filll] fillstr(substring, number): Returns a string where the input substring is repeated the specified number of times. Arguments [str] substring: The substring to repeat. [int] number: The number of times to repeat the substring. [numberss] dec2bin(number, [length]): Converts an integer into its binary representation and returns it as a list of booleans. Arguments [int] number: The input number. [int] length (optional): The desired length of the output vector. [nnmmbrss] atoi(string, [base]): Returns the numeric value represented by the input string. Arguments [str] string: The string to convert. [int] base (optional): The base conversion (2 for binary, 10 for decimal, and 16 for hexadecimal). Usage Examples [new_vvecrtt] new_vector(3) // creates a vector [0,0,0] [spllt] split("Hello world", " ") // ["Hello", "world"] [stvveecccrrtt] str2vec("foo") // ["f","o","o"] [subsst] substr("Hello world", 7) // "world" [fflslttrrtreeesstrrng] fillstr("hey", 3) // "heyyeyy"
