DUMASLang

DUMASLang is a language based on the gimmicks of Chef Michel DUMAS in his YouTube videos.

This is just a fun little side-project done while building a python meta-compiler for class.

Install

git clone

Run

The command takes 2 arguments :

• The path to your file
• Optional: A grammar name without the .txt if you want to use your own grammar (add it in the grammars folder) -> This is a metacompiler so it can compile any correct grammar

python main.py </path/to/file> <optional: grammar_name>

sh dumas.sh </path/to/file> <optional: grammar name>

dumas </path/to/file> <optional: grammar name> # you need to set an alias pointing to dumas.sh first

Syntax

Check the different examples available in the examples folder

Program structure

Just like every chef's video our program starts with :

Salut les amis bienvenue à la maison

and ends with :

Maitre d'hotel le plat de la table 55 est prêt on enlève!

Declaring variables

⚠️ In this language all variables are global variables.

To declare variables use the syntax below - Types and examples here

je réserve variable_name = value

User inputs can be entered using :

je réserve user_input = je lis tous les commentaires

The input has to be formatted as it would in the program (e.g strings have to be between double quotes)

Conditions

Compare 2 symbols, symbols can be one of the followings :

• strings
• integers
• floats
• variables

(so no calculations or user inputs)

symbol1 == symbol2
symbol1 != symbol2
symbol1 <= symbol2
symbol1 >= symbol2
symbol1 < symbol2
symbol1 > symbol2

Loops

Only while loops are implemented - Example

je réserve i = 0

tourne et retourne tant que Condition
    je réserve i = on calcule i + 1
comme ça

If / Else

Only ifs and elses have been implemented so in order to make an "else if" statement you have to combine multiple ifs and elses. See the example

The syntax is the following for a simple if statement

contrôle de la qualité Condition
    on dresse "condition is ok"
terminé

The syntax for an if/else

contrôle de la qualité Condition
    on dresse "condition is met"
sinon c'est pas encore bon
    on dresse "condition not met"
terminé

Functions

Example of a recursive function

Functions are declared with the following syntax

Machine miracle hello_world :
    on dresse "Hello world! :D"
en effet c'est prêt

You can also pre-declare variables to avoid errors

Machine miracle addition on mélange a et b :
    je réserve c = on calcule a + b
en effet c'est prêt

To call a function you don't need to give the parameters they should be declared before calling the function

Feu allume hello_world !

je réserve a = 3
je réserve b = 4

Feu allume addition !
on dresse c
