Vipr is a high-level language pretending to be a low-level one, making it not very efficient.
However, it is fun to use and to learn the basics of programming with :D
It is my first "large" project, and helped me learn a lot!
The code window is the text area on the left of the screen.
This is where you enter your code, and the code gets run!
The console window is the text area on the right of the screen.
This is where all the code gets run, and you see the output!
When you press this, the code you have typed gets run!
It also allows you to stop the code, when it is running.
Using the command txt allows you to print anything after it, for example,
txt Hello world!
You may also use any variables that have been
declared, using a ~. For example, if a "name" variable had been declared, you could say
txt Hi, my name is ~name~
There is also the new command, allowing you to make a new line based on the argument, for example, new 2 would be the same as pressing enter twice. Redundant, possibly.
Using the command slp is really simple, as it merely makes the program wait for an amount of time before going to the next line. If I were to type
slp [enter int here], where it would wait for n seconds, where n is the integer inputted divided by 100.
You may also use a variable that is an integer using
slp ~variable
Jumping is Vipr's form of loops and if statements. Each one has its own respective command, with jumping being jmp,trying being try, returns being rtn, and labels being lbl.
The jump command makes it go to another line, so if I were to input
jmp 13
it would jump to line 13, and read line 13 onwards.
You may also use a variable that is an integer, using
jmp ~variable~
Trying is slightly more complex, where you can check if something (can be a string, a variable, etc) is equal, less (must be numbers), or greater (must be numbers) than another thing (string, variable, etc). Examples:
Check if variable "number" is greater than 27, if it is, go to line 6
try 6 grt ~number~ 27
You can replace grt with lss (check if it is less) or eql (check if it is equal, also works with strings)
After you make a jump or a try, you can use rtn to go back to the line you were at, making it really easy to make functions.
To use label, use the lbl command. Labels make it super easy to make functions or go back to a part of the code. Setting a label allows you to make a name for that part of the code, and you can insert that name and it jumps you back!
To set a label, use
lbl set name
This would set a label on that line as "name".
If you want to go back to that line, you can use
lbl jmp name
Which would allow you to jump back to the line!
Variables in Vipr are easily the most important things, and you can do a lot with them. Use the var command with the variable name after it, and then anything you want!
To use the string command, use var str, and then another argument afterwards. There are a few things you can do with strings, such as simply setting it:
var hello str set Hello, world!
You may also use variables in this.
You can also merge two strings, using the mrg argument:
var greeting str set Hi there,
var name str set Bill
var sayHi str mrg ~greeting~ ~name~In this case, the variable sayHi would be Hi there, Bill.
Unfortunately, you can only use variables in this.
To get the length of a string, use the len argument, or
var length str len ~name~
This would get the length of the variable name, for example, if name were to be Jamie, it would return 1.
Using the inp argument (var name inp Text here) you can get the users input! Anything after the inp will print out, and the user can type anything in, and the variable gets set to that! You can also use variables in the text! Example:
var name inp Hi there! What's your name?
Copying a variable is a really simply task, merely using the cmd argument, or for example:
var name cpy blank
In this example, the new variable name would be the same as the variable blank.
Blank variables are another really simple thing, using the bnk argument, or for example:
var name bnk
The variable name would be blank, having nothing in it.
This is going to be long.
To set a number as a number (float/int), use the num set, or var name num set 27.
In this case, the variable name would be 27.
To add two numbers, use num add, or var name num add ~epicNumber 27.
In this case, the new variable, name, would return the variable epicNumber plus 27! You can add two variables, two numbers, anything!
To subtract a number from another, use num sub, or var name num sub ~epicNumber~ 27.
In this case, the new variable, name, would return the variable epicNumber minus 27!
To multiply two numbers, use num mlt, or var name num mlt ~epicNumber~ 27.
In this case, the new variable, name, would return the variable epicNumber times 27!
To divide a number by another, use num div, or var name num div ~epicNumber~ 27.
In this case, the new variable, name, would return the variable epicNumber~ divided by 27!
To get a random number, use the num rng command.
var name num rng 6 27
The new variable, name, would return a random number from 6 to 27. You may also use a variable!
To round a number to its nearest whole, use the num rnd command.
var name num rnd 27.2
The new variable, name, would return 27, as 27.2 rounded is 27. You may also use variables!
If you want to round it up, you can use the num cil command instead of num rnd, and if you want to round down, use the num flr command instead.
To use sine, cosine, or tangent, you can use sin, cos, and tan respectively! Example:
var name num sin 45
The new variable, name, would return the sin of 45! You can also use variables!
To use the modulus (remainder) operation, use the command mod, for example:
var name num mod 27 7
This would return 27 mod 7, or 6.
You can also use variables!
To use an exponent, use the pwr command!
For example:
var name num pwr 3 4
The new variable, name, would return 3 to the power of 4, or 81!
