Support

The language currently supports

• Basic IO on standard IO
• Mathematic manipulations on float/integers
• Boolean Algebra
• Array manipulations
• String manipulations
• Variables

IO

Three instruction are available to handle IO

• CROISSANT is the general print function it natively supports printing integers, boolean, floats and strings
• PAINAUCHOCOLAT is the general printf function, the only placeholder is %d
• ECLAIR is the read standard input function. If you use it without args like that:

  ECLAIR CHOUQUETTE CLAFOUTIS
  

  it passes the input through the type inference algorithm, i.e typing 1 in the standard input will gives you an integer of value 1 while if you use it with any argument like this

  ECLAIR CHOUQUETTE 0 CLAFOUTIS
  

  it gives you a string of the input, without passing it through the type inference algorithm.

Mathematics

The entire list of instructions available and supported by the language is available in the wiki.

The majority of these instructions supports indifferently integers and floats (the two type are named numbers). However, the result will be displayed as a float if you supply at least one argument as a float, even if it could be an integer, as seen here

You should pass the answer through the floor function if you need an integer

Boolean algebra

Booleans

• CUPCAKE is true
• POPCAKE is false

  Algebra

  All operators are functions, the list of baguette translation is available on the wiki

The language supports

• OR
• AND
• XOR
• NOT
• =
• >
• >=
• <
• <=

Array Manipulations

The language supports basic array manipulations, the whole list is once again available on this page of the wiki

• [ is BABAAURHUM
• ] is CHARLOTTEAUXFRAISES

The separator between arguments is either a blank if you’re using the default lexer or a comma with the new lexer, the default lexer reads and ignore the comma.

You can

• Create an array of size n
• Create a matrix of size n by p
• Access to the nth element of an array
• Change the nth element of an array
• Generate a string representation of an array

String Manipulations

The language implements natively a string module implementing some useful functions, the translation is available on the string page of the wiki

• Create a string with n times the supplied string
• Concatenate two strings
• Accessing the nth character of a string
• Replace all occurrence of s1 in s2 by s3
• Split a string at each occurrence of a string
• Transforming a string into an array of chars
• Transforming an array of chars into a string

Example:

Conversion from string

You can convert string to integers/floats/booleans, for example:

CARROTCAKE CHOUQUETTE PARISBREST 12 PARISBREST CLAFOUTIS

converts a string to an integer

while

GALETTEDESROIS CHOUQUETTE PARISBREST 12.2 PARISBREST CLAFOUTIS 

converts a string to a floating point numbers

and

FRANGIPANE CHOUQUETTE PARISBREST true PARISBREST CLAFOUTIS

An EXCEPTION is raised if you supply a parameter which is not convertable.

Conversion to string

The conversion to string is the same instruction for every type, it is FROSTING

FROSTING CHOUQUETTE 10000 CLAFOUTIS

Variables

Baguette# do not have a real system of scopes and variables, all registered pseudo-variable with the QUATREQUART instruction are readable with the MADELEINE instruction everywhere in the program.

It allows developing function-like labels which can uses and manipulates the pseudo-variables defined in the program, in the label.

To learn more about variable, labels and gotos usage see the advanced usage page !
