Nurture

Yet another programming chrestomathy

Every language directory contains:

  • README with a quick how to compile & run your program. {program} denotes a placeholder.
  • Bare minimum hello, world example.
  • Possibly some cool Fibonacci implementations. The program will accept an argument from the command line.

Other directories:

  • build build file templates
  • database info about working with specific databases + scripts
  • editor cool editors
  • esolang other ways of talking with the computer
  • other is a folder with some random and relatively funny stuff
  • structure common data structures used for config or transport
  • transpiler is a collection of helloworld files for transpilers

Here is an overview that compares the helloworld binary for compiled languages in bytes using the default build command on the CLI. Only explored languages with a compiler are included. These binaries are build on Arch Linux x86_64 5.2.11-arch1-1-ARCH.

The simplest of programs. Mandatory test that has to be done before doing anything in that language. It tests your ability to press the right sequence of buttons to produce something on the screen. The reward is a greeting to the world and possibly a working program.

Syntax that can be learned, depending on the language or implementation:

  • Produce output
  • Use of String type
  • Create entry point for program

As an added benefit you know how to compile/build and/or run a program.

Although a simple sequence at first, one can learn much about a language by implementing a function that returns the Nth fibonacci number. A factorial function is also fun to implement.

Syntax that can be learned, depending on the language or implementation:

  • Creating a function
  • Calling a function with parameters
  • Optional parameters
  • Reading (user) input
  • Type casting to other types
  • Returning result from a function
  • Produce pretty output
  • Create variables in memory
  • Swap two variables in memory
  • If/then/else logic
  • Comparison operators
  • Use of recursion
  • Use of exponentiation
  • Use of rounding
  • Use of standard Math library

Test

fib(N)
  • Test accuracy N = 25, N = 50, N = 80, N = 100
  • Test fibTailRecursive N = 1000 for a stack overflow
  • Test speed for fibLinear N = 1000000

The fib file

Function name Time complexity Remarks
Fib O(n^n) Slow because of unoptimized recursion, but the best to read
Fib linear O(n) Imperative definition, ok to read
Fib formula O(1) Binet's formula is precise till approximate 70th fib number because of floating-point arithmetic
Fib tail recursive O(n) Optimized recursion. Easy to read
Fib formal O(n^n) Explicitly state all code paths. F0 = 0, F1 = 1, Fn = Fn-1 + Fn-2
Fib list O(n) Return a list from 0 to N
Fib generator O(n) Generate the Nth number based on the amount of next calls (starting with 0)
Fib fast doubling O(log n) Precise and fast implementation, kind of readable

  • How to package in every language
  • How to debug without proprietary software
