Visual Basic - How to create a simple programming language.

This is my video on how to create a very simple programming/scripting language. I will be doing updates so keep an eye out.

If I get 100 likes ill think about adding in variables ;)

[Naco]

I worked out how to do variables!!!

First add this to the start of your code:
Dim variables As New Dictionary(Of String, String)()

This must only be run at the start so run this when the user clicks "Run"

Here is to add a variable: variables("variablename") = 10
Here is how to check a variable's value: variables("variablename")

So do something like this:
If testarray(0) = "var" Then
variables(testarray(1)) = testarray(2)
If testarray(0) = "getvar" Then



The command "var" is structured like this: var [variable name] [variable value] this command is used for creating a variable

The second command "getvar" prints the variable giving and is structured: getvar [variablename]

Hope this helps.

For variables:
Dim var As New Dictionary(Of String, String) ' Put this before the RunToolStripMenuItem_Click sub

If testarray(0) = "var" Then
var.Add(testarray(1), testarray(2))
End If

This is really great i really liked the idea

You are AWESOME! Thanks very much man :) . But can you make a tuto for C# please?

i added booleans:
If codeArray(0) = "Bool" Then
If codeArray(2) = "true" Or "false" Then
Console.WriteLine("boolean " & codeArray(1) & " has been set to " & codeArray(2))
End If
End If

This is a little bit of codes i used for my programming language:
create:ball with dim :5px;5px ;
func.rotate.whileOnclick =
func.move"In Direction pressed"; If key.pressed = "A" then move = "5l"
loop.start = "OnKeyPress.OrClick then "loop.start.until = "keyReleased"

Simple game language...i will try to implement more! So what do you think?

In my language I have added file writing, variables, inputs and am working on an interactive game engine.

Hi! This is great tutorial! Also, I had a request. Could you do a tutorial on how to make the programming language export the program as .exe file or some other file that runs on windows(like batch file .bat)? For example => “the way visual studio builds an .exe file.” Thanks!

[Robobbly]

Thats great! You sound really good at programming :/ im envious

[androshchukx]

whenever I try to run the app, it does not want to start... What could I be doing wrong?

[aethletiic]

i have an error saying 'Index was outside the bounds of the array.' for the print one when i type print hello

[gambitdevs]

You got 90 likes, and my subscribe, i'd love to see one of these with variables, please, thanks

[Robobbly]

say it was like message ("hello") split it first. so you have "message" and "("hello")". Now we have that we can tell that you want a message. Then tell it to split the string "("hello")" firstly at " (" " and then " ") ". Now you just have hello as a string :)

Robeet Dilley, I like your tutorial but there is a problem
1.When i try to put a space while using print statement it does not prints that.
I hope you will help me

[gavindorough]

it says i have need an end of statement on lines 9 and 10, and that i need expression on line 17. please help now.

[Robobbly]

looks good although why is so much in between " ". That usualy defines something that the computer doesn't need to parse so putting "In Direction pressed" is a bit wierd?

[Robobbly]

Nice man! Hope you can show it to me sometime? :D

[Gaming]

sadly my avg is detecting it as a virus so no language :[

[eminchniti]

Error 1 Type of 'i' cannot be inferred because the loop bounds and the step clause do not convert to the same type

Hello! This gets more tricky. What i would do if i where you is create another program like mine that looks for a file called program.txt or whatever and opens that on start up and then runs it. If you did this and placed them both into a self extracting EXE which just runs the program... it would run it just like an EXE. That probably didn't make sense so do you want a tutorial video? :)
