# bf-codegen
A compiler backend that emits [Brain***](https://en.wikipedia.org/wiki/Brain***) as an intermediate language
This shouldn't exist. I'm sorry.
## Examples
### Hello example
```python
import bf_codegen
from bf_codegen import interpreter
context = bf_codegen.Context()
hello_str = context.build_store("Hello, Sailor!\n")
context.build_print(hello_str)
prog = context.code()
assert interpreter.run(prog) == "Hello, Sailor!\n"
```
### Loop example
```python
## prints numbers counting down from 9 to 1
import bf_codegen
from bf_codegen import interpreter
context = bf_codegen.Context()
newline = context.build_store(["\n"])
def body():
# add 48 to get the ascii value of the digit
sum = context.build_add(loop_times, 48)
context.build_print(sum)
context.build_assign(sum, 0)
context.build_print(newline)
# 9 is the number of times to loop
# the loop implicitly decrements the value of loop_times and stops when it reaches 0
loop_times = context.build_store([9])
context.build_loop(
times = loop_times,
body = body
)
prog = context.code()
assert interpreter.run(prog) == "9\n8\n7\n6\n5\n4\n3\n2\n1\n"
```
