How To Make A True Coding Language: Part 1
CSharpIsGud (939)

Im making this tutorial series because almost every language i've seen posted to repl talk doesn't use parsing algorithms and I think it would be nice to see some that do. There are a couple flavors of these languages, typically they come in 2 forms
1) They use string splitting and regular expressions

Technically you can call this "parsing" or a language of some sort.
But you will very quickly discover you run into syntax limitations like having to have a separator for a lot of things.
set:var,Hello World;print:var

2) They do nothing at all but define some classes or variables

I don't know how people get away with this and then tell you to calm down when someone calmly separates what it is from what it isn't. Even when put in the best possible words as to not directly attack the repl itself.

Which is why I have decided to create a tutorial on making a programming language in hopes people start making ones that don't have the above flaws.

This tutorial is going to go bottom to top using no dependencies at all and will show creation of a lexer all the way up to the hand made recursive-descent parser!

The Lexer (or scanner, tokenizer, whatever you wish to call it)

The other components will get their own files as they are created.

@JaydenLiu1 Typically if you actually call out said things as not being what they said they are they will go crazy.
There are plenty of things they may or may not reply with but I can think of some probable ones and their counterparts:
"Dude, chill" ('chilling' is not necessary when you are already 'chill')
"Hater" (This defeats itself.)
Special: "I diDn'T sAy iT wAs A rEAl C0diNG lAnGuAGE!" ('coding language' implies that it is a coding language)
"It took a lot of effort for him to make that" (If it did, you wouldn't be commenting about how it can be done in less than 10-30 minutes)
"Stop." (If they can't actually think of any reason you shouldn't call out how easy it is to do what they did)
