BFIL

Brainfuck intermediate language

Use the compiler with the following options:

• -f filename
• -o output filename
• -O output filename extension
• -p input file path
• -P output file path
• -k keep the window open after compilation is finished.

Example usage: BFIL -f compare.bfil -p "path" -P "path" -o "compare"

Numbers that have a ? in front of them are addresses.

To specify the memory size your brainfuck interpreter has, use memsize. This is the only thing in this language that uses hexadecimal values. memsize 0x8000

In order for your code to work, you need to reserve memory using reserve: reserve ?16 ~ ?32*

To load a value into an address, use load ?0 ~ 10*

You can also load multiple values using loads ?0 ~ 8 ~ 1 2 3 4 5 6 7 8*

You can add numbers using add: add ?0 ~ ?1* This means ?0 += ?1.

You can do the same with subtraction by using "sub" instead of "add".

Increment an address' value with increment ?0. Use "decrement" to decrement instead.

Ascii output: aout amount address address address...: aout 2 ?0 ?1

Value output: vout amount address address address... ~ separating_character_address: vout 2 ?0 ?1 ~ ?2* Use ?-1 if you don't want a separation character

Constant output: Output that is known at compile time. Outputs one word at max: cout Hello

Console input (one character only): read ?0

Set a range of cells to 0: empty ?0 ~ ?10*

To copy a value, use copy ?target ~ ?source*

Compare*:

compare ?0 = ?1 ~ ?2
compare ?0 < ?1 ~ ?3
compare ?0 > ?1 ~ ?4

Logic*:

logic ?address or ?address ~ ?address
logic ?address and ?address ~ ?address
logic ?address not ~ ?address

Looping:

whileNotZero ?address
    [some code]
endLoop

Comments begin and end with a #. Ergo:

This is not a comment
# This is a comment
This is still a comment #
This is not a comment

You can use alias to create aliases*:

alias ?0 ~ x
load x ~ 10

The inline keyword keeps the next token in the compiler output:

...
inline test
...

results in someCode test someCode

*You can use anything instead of ~. I like to use "+=", "-=", "<-", "->".

If you want to compile this yourself, I am on windows and used g++ *.cpp to compile. This should work, assuming you're running g++ in the source directory. You may need to modify main.cpp when not using Windows because of filepath stuff because Windows just likes its \s for paths. main.cpp is just responsible for the command line interface so you could easily make your own if you don't like that mess of a command-parameter-thing I coded.

Feel free to open an issue if you have a suggestion or encounter a bug!
