Oneliner is a esoteric programming language, where every program is supposed to have only one line. Every program with more than 1 line has a one-line version. Newlines are not ignored.

Overview

Oneliner is based on 3 objects: C, c and V. C (stands for Code) is the main object. It can execute code and store variables. c (stands for code) is a predefined Code object. V (stands for Value) is a non-constant value.

Oneliner uses the build technique, where blocks are added one-by-one and then executed at the same time.

Syntax

Here's how to write programs using Oneliner:

Code	Description	Pseudo-code
C()	Initialize a new Code object	Code()
c()	Get variable enviroment	code.variables
c()["varname"] or c["varname"]	Get the value of a variable	varname
c()["varname",123]	Set the value of a variable	varname = 123
c().g("varname")	The function version of c()[...]	varname
c().s("varname",123)	The function version of c()[..., ...]	varname = 123
c()()	Go back to Code	code.variables.code
c[function,(1,2,3),{"a":45}]	Add a block	code.addBlock(function(1, 2, 3, a=4))
c(1)	Execute all blocks and clear the build	code.executeBlocks(clear=True)
c.lr	The return value from the latest executed block	code.lastReturn
c.glr()	The function version of c.lr	code.getLastReturn()
c.b()	Execute all blocks without clearing the build	code.executeBlock(clear=False)
c.c()	Clear the build	code.blocks = []
c.f()	Create a function copy of the Code object with fixed blocks	code.asFunction()
c.i(C()[boolean,(1,),{}].f(),print,("Test",),{})	Add an if statement to the build	code.addBlock( if(boolean(1)) { print("Test") } )
c.ii(...)	Run an if statement without adding it to the build	if(boolean(1)) { print("Test") }
c.ie(C()[boolean,(1,),{}].f(),print,exit,(1,),{})	Add an if-else statement to the build	code.addBlock( if(boolean(1)) { print(1) } else { exit(1) } )
c.iie(...)	Run an if-else statement without adding it to the build	if(boolean(1)) { print(1) } else { exit(1) }

The rest will be added soon.

Examples

Hello, World!

Here's a simple one:

c[print,("Hello, World!",),{}](1)

Explanation:

 c[                     Add a block to the build
   print,               The function to be called
   ("Hello, World!",),  Positional arguments
   {}                   Keyword arguments
 ]                      Block end
 (1)                    Execute and clear the build

Truth-machine

Oneliner:

c()["i",num(input())]()[print,("1",),{}].ie(C()[boolean,(c["i"])].f(),c.b,c.c,(),{}).iie(C()[boolean,(c["i"])].f(),c.b,c.c,(),{})

Explanation:

1) Input is saved to i as a number: c()["i",num(input())]
2) Print 1 is added to the build: ()[print,("1",),{}]
3) Continue the loop by executing the build if i is 1: .ie(C()[boolean,(c["i"])].f(),c.b,c.c,(),{})
4) Start the loop with an instant if-else: .iie(C()[boolean,(c["i"])].f(),c.b,c.c,(),{})
