grapejuice

not that Grapejuice

The Grapejuice you're looking for is on Gitlab. This is just a dumb barely-working project I made as a teen.

grapejuice

Please note: I created this to see how it would be like to create a simple programming language, and as such it is not recommended that you use this for anything more than a couple laughs

Grapejuice installer for linux
Grapejuice is a language that I made, which compiles into c++
My friend is currently working on a Windows version

INSTALLATION:

In terminal, as root user, cd to grapejuice_release file. from here, run "source installer"

USE OF COMPILER:

"winepress" opens winepress compiler "winepress2 grapename juicename" compilers with parameters

DOCUMENTATION:

misc.: every line must end with an enter press tabs are ignored $ as the first character in a line denotes a comment "head" and "body": every program must include the following line: ENTRY

	everything before it is the head. everything after is the body.
Functions:
	defining a function:
		In head of file:
		[datatype (any c++ data type, or "string")]F_FunctionName [datatype]param1 [datatype]param2 ...
			code
			TOSS returnvalue
		ENDDEF
		
		for example:
		[float]F_add [float]num1 [float]num2
			[float]num1+num2 -> total
			TOSS total
		ENDDEF
	calling a function:
		In body:
		F_functionName param1 param2 ...
		(note that the parameters must be variables, not literals)
		for example:
		F_add one two
	built-in functions:
		F_RAND
			returns a random number from 0 to 255
		F_RAND_char
			returns a random letter
		F_PRINT message
			prints message to the console
		F_NL
			prints a line break
		F_BEEP
			produces hard drive beep
		F_GET_string
			prints "::", gets user input, and returns value as string.
		F_GET_float
			prints "::", gets user input, and returns value as float
		F_PAUSE
			waits for user to press enter
		F_INT_TO_CHAR int
			returns a character with assci value of int
		F_CHAR_TO_INT char
			returns ascii value of char
logic:
	use one per line with no spaces
	multiply
		*
	divide
		/
	add
		+
	subtract
		-
	and
		&
	or
		|
	not
		!
	greater than
		>
	less than
		<
	equal to
		=
flow:
	if/else if/else:
		IF booleanVarible
			code
		ENDIF
		ELSEIF booleanVarible
			code
		ENDELSEIF
		ELSE
			code
		ENDELSE
	while:
		WHILE booleanVariable
			code
		ENDWHILE
	timer:
		WAIT intVariableSeconds
variables:
	declaring a varible:
		[datatype]valueOrExpression -> name
		
		examples:
		[int]5 -> five
		[int]3+3 -> six
	changing a varible:
		valueOrExpression -> name
		
		example:
		4 -> five
	declaring an array:
		[datatype]{index0 index1 index2 ...} -> name
		
		example:
		[int]{1 2 3 4 5} -> oneToFive
	calling an array:
		name{index}
		
		example:
		oneToFive{1}
	strings:
		the value for a string must be between quotes.
		the symbol @ is the esape character
		@_ is a space
		@A is @
			
		example:
		[string]"strings@_and@_@A's" -> derp

example programs can be found in /projects each folder contains a .grape which is the uncompiled version, and a .juice which is the compiled version.

quick example

[int]F_foo [int]number
	number+1 -> out
	TOSS out
ENDDEF
$comment
ENTRY
[int]F_GET_float -> picked
[int]F_foo picked -> thing
F_PRINT thing
F_NL
F_PAUSE
