SpeechProg

SpeechProg is a esolang by Mihai Popa. You use natural language for programming.

Syntax

Comments are done with a hash, but unit tests exercising this code are done with a greater-than sign.

Examples

Hello, world!

On "Say Hello, world!", reply with "Hello, world!"

# This can be tested
> Say Hello, world!: Hello, world!

# This can be created within SpeechProg
> Say Hello: Hello, nice to meet you!

XKCD Random Number

On "XKCD", reply with "4"

> XKCD: 4

Count from 1 to 10

On "Count me!":
    Set X to 1
    Loop from this until the end
    Reply with X then a space
    Set X to the evaluation of X plus 1
    # "Set X to the evaluation of X + 1" is also the same
    If X is 11, then stop the loop

> Count me!: 1 2 3 4 5 6 7 8 9 10 Done.
> Count me!

Say if a number is a perfect square

On "Is X a perfect square?":
    Set S to the square root of X
    Set R to the floor of the value of S
    Set C to the evaluation of S minus R
    If C is zero, then reply with "Yes!"
    But if C is not zero, then reply with "No!"

> Is 16 a perfect square?: Yes!
> Is 25 a perfect square?: Yes!
> Is 30 a perfect square?: No!

> Is 60 a perfect square?
> Is 49 a perfect square?

Square root and cube root of pi and e

On "Square root of pi":
    Set P to the square root of pi
    # It's the same as this:
    # Set P to the value of pi
    # Set Q to the square root of P
    Reply with P
On "Cube root of pi":
    Set P to the cube root of pi
    # It's the same as this:
    # Set P to the value of pi
    # Set Q to the cube root of P
    Reply with P
On "Square root of e":
    Set P to the square root of e
    Reply with P
On "Cube root of e":
    Set P to the cube root of e
    Reply with P
> Square root of pi: 1.772453850905516
> Cube root of pi: 1.464591887561523
> Square root of e: 1.648721270700128
> Cube root of e: 1.395612425086089

e with just pure math

# Calculates e with just pure math.
# Mihai Popa, accuracy is quite modest.

On "Calculate e":
    # First run, which is 1
    Set X to 1
    # Second run, which is 1 + (1 / 1)
    Set Y to the evaluation of X divided by X
	# Sets Z to 2
    Set Z to the evaluation of Y plus X 
    # Third run, which is 1 + (1 / (1 * 2))
    Set W to the evaluation of Y multiplied by 2
    Set A to the evaluation of X divided by W
	# Sets B to 2.5
    Set B to the evaluation of A plus Z
    # Fourth run, which is 1 + (1 / (1 * 2 * 3))
    Set C to the evaluation of W multiplied by 3
    Set D to the evaluation of X divided by C
	# Sets E to 2.666666...
    Set E to the evaluation of B plus D
