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.
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)
Located in lexer.py
The other components will get their own files as they are created.
@JaydenLiu1 People say that, because they aren't languages.
If its fake, then people will call it fake regardless of if they hate it or not.
In case you have not seen, some people have literally just done this and called it a "coding language"
class Console: def WriteLn(str): print(str) console = Console() console.WriteLn("LOOK AT MY NEW LANGUAGE")
Luckily these kinds of things have sort of died down on replit now.
Simply calling it "hate" to call out what something is and is not does not change the fact that the above snippet is just python with a defined class.
