A BF-derivative esoteric programming language.
Prado (dedicated to and named after @Valensce's dog, shown above) is an esolang that translates to BF to be interpreted. Prado files have the .pdn extension.
Prado's Linguist colour will be #d0a92c (gold). Until Prado is added to Linguist, it will be represented by BF on this repository page.
app/main.py is a Python 3 interpreter for Windows that translates between Prado, BF and text.
The text-to-BF (and therefore text-to-Prado) functionality is thanks to this Stack Exchange post. Long texts may take a while to encode and decode, but it should get there eventually. Probably.
Please note that text-to-BF and text-to-Prado are not optimised.
Also, please remove comments from BF/Prado code before running. The interpreter currently fails to convert invalid BF/Prado characters. This will likely not be addressed.
If you encounter any problems with the interpreter, please create an Issue.
To install dependencies, please do the following:
- Clone this repository
- Open a commandline in the project directory
- Run this command
python -m pip install -r requirements.txt| BF | Prado |
|---|---|
> |
x |
< |
y |
+ |
n or +n depending on context |
- |
-n |
. |
= |
, |
Officially z, but not properly implemented |
[ |
( |
] |
) |
Where n is the amount of +s or -s, and multiple xs or ys are given the power of their length. x or y directly followed by a numeral indicates an exponent. = is always preceded with a new line. For example:
>++++[>>++++++++<<-]>++[>---<-]>.Becomes:
x+4(x2+8y2-1)x+2(x-3y-1)x
=xy
If you don't understand, try out the text-to-Prado translator.
In BF, the following program outputs "Hello world!":
++++++++[>+++++++++<-]>.
<++++++++++[>+++<-]>-.
<++[>+++<-]>+.
.
+++.
<++++[>>++++++++<<-]>>.
<<++[>++++<-]>.
<++[>----<-]>.
+++.
<++[>---<-]>.
<++[>----<-]>.
>+.This can be translated into Prado as:
8(x+9y-1)x
=y+10(x+3y-1)x-1
=y+2(x+3y-1)x+1
=xy
=3
=y+4(x2+8y2-1)x2
=y2+2(x+4y-1)x
=y+2(x-4y-1)x
=3
=y+2(x-3y-1)x
=y+2(x-4y-1)x
=x+1
=xy
More examples like this can be found in the /examples directory.
One of the biggest contributions you can give is creating your own repository containing Prado code so it can be added to Linguist. Please either fork this repository or make your own code with the interpreter. If you have any questions, head over to Discussions.
