Tipe - typed pipe

Tipe allows you to create constructions similar to pipe operator, where result of a function used as an input of next function

Instalation

pip install tipe

Examples

>>> from tipe import Pipe
>>> 
>>> Pipe(2).pipe(lambda x: x + 1).pipe(float).unwrap()
3.0
>>> Pipe([2, 3, 4]) \
...         .pipe(len) \
...         .pipe(lambda x: x + 1) \
...         .pipe(float) \
...         .unwrap()
4.0
>>> Pipe(2).pipe(range, 4).pipe(len).unwrap()
2

Equivalent for examples above would be

>>> float(2+1)
3.0
>>> float(len([2, 3, 4]) + 1)
4.0
>>> len(range(2, 4))
2

API

Pipe()

To use .pipe() on a value wrap it with Pipe class

>>> Pipe(2)
Pipe(2)

Pipe.pipe()

Pass function to execute on Pipe value and additional params for it. Wraps function result in Pipe and returns it

Pipe.check()

Like Pipe.pipe() but does not change the value inside Pipe. May be useful for debugging purposes

>>> Pipe(2).pipe(lambda x: x ** x).check(print).pipe(float).unwrap()
4
4.0

Pipe.unwrap()

Returns value from Pipe

Short forms

For convenience you can use P as short version of Pipe and short versions of the methods:

• p: pipe
• c: check
• u: unwrap

Types

tipe tries its best to stay typesafe, so every function knows what exactly what it returns as long as it is inferable from arguments
