Folders is an esoteric programming language, created by Daniel Temkin in 2015, which encodes the program entirely into the directory structure.
All names of the folders as well as their contents are completely ignored. Instead, the commands are encoded in the nesting of folders within folders.
Let me say that again: THE SOURCE CODE IS THE DIRECTORY STRUCTURE. Lol.
This is a Python implementation of Folders for all to enjoy!
Folders is (was originally) implemented in C#.
Install from pip
Simply install the
Folders command line interpreter
pip install Folders
Give the folder of the program you wish to run as an command line argument
Folders sample_programs/HelloWorld # => Hello, World!
If instead you would like list the Python code to stdout, use the
Folders -l sample_programs/HelloWorld # => print("Hello, World!", end='', flush=True)
The implementation is just the python file, folders.py and has no dependencies, so if you'd like you can clone the repo and run
python ./folders/folders.py instead of pip installing and use it the same as in the examples above.
The language details are on the esolangs wiki, but I've put it here for reference.
For example, take a look at the Fibonacci sample program.
The root folder contains a list of command folders - in this case labelled
Nf2.., but the names don't actually matter except the alphabetical ordering - the first folder (which I've labelled with an
init) is the first "sub-folder", the next is the second, etc.
Commands take the following form
Command # of folders Details
if 0 folders Second sub-folder holds expression, third holds list of commands
while 1 folder Second sub-folder holds expression, third holds list of commands
declare 2 folders Second sub-folder holds type, third holds var name (in number of folders, ex. zero folders becomes "var_0")
let 3 folders Second sub-folder hold variable name (in number of folders), third holds an expression
print 4 folders Second sub-folder holds expression
input 5 folders Second sub-folder holds variable name
Expression folders take the following form:
Type # of folders Details
Variable 0 folders Second sub-folder holds variable name
Add 1 folder Second sub-folder holds the first expression to add, third holds second expression
Subtract 2 folders Second sub-folder holds the first expression to subtract, third holds second expression
Multiply 3 folders Second sub-folder holds the first expression to multiply, third holds second expression
Divide 4 folders Second sub-folder holds the first expression to divide, third holds second expression
Literal Value 5 folders Second sub-folder holds the type of the value (as described by types below, ex. two folders for a string)
Equal To 6 folders Second and third folders hold expressions to compare
Greater Than 7 folders Second and third folders hold expressions to compare (takes the form : second folder > third folder)
And finally type folders take the following form:
Type # of folders
int 0 folders
float 1 folder
string 2 folders
char 3 folders
Note on this implemementation
char types are 8-bit only. But, you can add into their variables to arbitrary length, so to get a very large number you can simply multiply it a bunch of times.
This is what the fibonacci program does.
The absolute power of folders
Behold, the mighty Truth Machine program:
A mighty meme-worthy point
All Folders programs are 0 bytes if you're on windows as it interprets an empty folder as 0 bytes.
The ultimate code golf!
