Introduction

In this page we will introduce the LABELS; GOTOS, and IF and what we can do with it. Reading the basic usage page is strongly recommended before reading this page.

The REPL do not as of now (03/09/2022) supports labels, the coding will be in a file called test.baguette you can find a syntax highlighter extension for Baguette# on VSCode on the marketplace here or typing ext install coco33920.baguette-sharp-support into the VSCode Command Palette

Labels

The label keyword is ICECREAM followed by a name in a string like PARISBREST test PARISBREST and the keywords MUFFIN/COOKIES which are BEGIN/END finally you need to close the block by a BAGUETTE like exposed here

test.baguette

ICECREAM PARISBREST test PARISBREST
MUFFIN

COOKIES BAGUETTE

You can put any code you want inside, just you must not put a BAGUETTE in any code inside it as it will interpret it as the end of the block. The file should look like this

test.baguette

ICECREAM PARISBREST test PARISBREST
MUFFIN 
    CROISSANT CHOUQUETTE PARISBREST Hello World! PARISBREST CLAFOUTIS
COOKIES BAGUETTE

we can execute the file with baguette_sharp --input test.bag, and we have… the following output

nothing which is nothing.

Because we have not called it!

GOTOs

We are right after the last section. To call it we need to use the PAINVIENNOIS keyword with the name of the label we want to call. Let get back to our code and add the instruction.

test.baguette

ICECREAM PARISBREST test PARISBREST
MUFFIN 
    CROISSANT CHOUQUETTE PARISBREST Hello World! PARISBREST CLAFOUTIS
COOKIES BAGUETTE

PAINVIENNOIS PARISBREST test PARISBREST

Executing it now outputs :

output

Order of execution

Let modify our code a bit

test.baguette

ICECREAM PARISBREST test PARISBREST
MUFFIN 
    CROISSANT CHOUQUETTE PARISBREST Hello World! PARISBREST CLAFOUTIS
COOKIES BAGUETTE

CROISSANT CHOUQUETTE PARISBREST Hello ! PARISBREST CLAFOUTIS
PAINVIENNOIS PARISBREST test PARISBREST

And executing it outputs,

order

The order is respected

Errors

Let modify our code to generate an exception in the label. Here a Syntax Error will be raised

test.baguette

ICECREAM PARISBREST test PARISBREST
MUFFIN 
    CROISSANT CHOUQUETTE PARISBREST Hello World! PARISBREST CLAFOUTIS
    MADELEINE CHOUQUETTE PARISBREST test PARISBREST CLAFOUTIS
COOKIES BAGUETTE

PAINVIENNOIS PARISBREST test PARISBREST

error The error line count is counting from the first line of the label (the count starts at 0, the first line is the 0th). And not from the file entirely. It counts even if you call another line before goto the label

If you try to access a label which do not exist, a standard label do not exists line will be output.

Variables and Labels

As explained in the basics there is not a real scope system in this language. In fact every pseudo-variable are elements of a shared hash-table, as such they behave a little like static variable. The following code

test.baguette

ICECREAM PARISBREST test PARISBREST
MUFFIN 
    CROISSANT CHOUQUETTE PARISBREST Hello World! PARISBREST CLAFOUTIS
    CROISSANT CHOUQUETTE MADELEINE CHOUQUETTE PARISBREST variable PARISBREST CLAFOUTIS CLAFOUTIS
COOKIES BAGUETTE

QUATREQUART CHOUQUETTE PARISBREST variable PARISBREST 10 CLAFOUTIS BAGUETTE
PAINVIENNOIS PARISBREST test PARISBREST

outputs

variable

But you need to define the variable before calling the label. If not an error is raised, the same as if you tried to access a variable before its definition as seen in basics.

IFs

The language supports IF statements, which are very similar to Labels (and internally works like a conditional called Label, but this is transparent to the developer)

The keyword for IF is SABLE and a statement is constructed like that IF condition THEN BEGIN code END; which in Baguette# translates to SABLE condition FRAMBOISIER MUFFIN code COOKIES BAGUETTE the following code prints something if CUPCAKE is true, which it is because CUPCAKE is the keyword for true.

if.baguette

SABLE CUPCAKE 
FRAMBOISIER MUFFIN 
    CROISSANT CHOUQUETTE PARISBREST this is true PARISBREST CLAFOUTIS
COOKIES BAGUETTE

which outputs

true

The CUPCAKE is meant to be replaced by any condition seen in basic. That is all for the Advanced Usage, in the next page we will learn how to do a basic loop and program a plus/minus integer game! The code for the labels can be downloaded here and for the if here

Functions

The language supports function definition and using them as if they were native functions, the functions are read after the main one of the standard library. They are defined with this syntax.

NAME { "PARAM_1" "PARAM_2" ... "PARAM_N" } (
  ..code..
);

The Baguette names are CRUMBLE for {; SCHNECKENKUCHEN for } and finally the return statements is a function it must be called with parenthesis, RETURN is APFELSTRUDEL.
Furthermore, arguments must be called through the MADELEINE function.
Finally, a function that take one argument and prints it like "Argument: <argument>" is like this

TEST CRUMBLE PARISBREST arg1 PARISBREST SCHNECKENKUCHEN CHOUQUETTE 
    PAINAUCHOCOLAT CHOUQUETTE PARISBREST Argument %d PARISBREST MADELEINE CHOUQUETTE PARISBREST arg1 PARISBREST CLAFOUTIS CLAFOUTIS 
CLAFOUTIS BAGUETTE

Calling it is simple, as if a TEST function existed, do not hesitate to role-play and add your own country’s or your favourite’s pastries :).

Load

You can load a B# file (containing for example functions) into another with the LOAD call (yet to be baguetified) LOAD "path/to/file"; in B# LOAD PARISBREST path/to/file PARISBREST BAGUETTE
