If you want more functional tools, you should look for another library. 6 | 7 | **This code repository has been moved to [Cool](https://github.com/abersheeran/cool), where it is actively maintained and there are more similar tools.** 8 | 9 | ## Install 10 | 11 | ``` 12 | pip install only-pipe 13 | ``` 14 | 15 | Or fetch from github 16 | 17 | ``` 18 | pip install git+https://github.com/abersheeran/only-pipe 19 | ``` 20 | 21 | ## Usage 22 | 23 | Use pipeline to pass data as a positional parameter to the next function: 24 | 25 | ```python 26 | from pipe import F 27 | 28 | range(10) | F(filter, lambda x: x % 2) | F(sum) == 25 29 | ``` 30 | 31 | Or you need to pass multiple parameters through the pipeline: 32 | 33 | ```python 34 | from pipe import FF 35 | 36 | 37 | def get_data(): 38 | return 1, 2 39 | 40 | 41 | get_data() | FF(lambda x, y: x + y) == 3 42 | ``` 43 | 44 | Use alias like follow code, you can use `map`/`filter`/`reduce` more conveniently: 45 | 46 | ```python 47 | from functools import reduce 48 | from pipe import F 49 | 50 | Filter = F(F, filter) 51 | Map = F(F, map) 52 | Reduce = F(F, reduce) 53 | 54 | range(100) | Filter(lambda x: x % 2) | Map(lambda x: x * x) | Reduce(lambda x, y: x + y) 55 | ``` 56 | 57 | ## Set Global 58 | 59 | Maybe you don't want to use `from pipe import F` in every file of the entire project, you can use the following code to set it as a global function, just like `min`/`max`/`sum`. 60 | 61 | ```python 62 | import pipe 63 | 64 | pipe.set_global(pipe.F, pipe.FF) 65 | ``` 66 | 67 | Maybe you also want to expose `functools.reduce` to the world, just like `map`/`filter`. 68 | 69 | ```python 70 | import pipe 71 | import functools 72 | 73 | pipe.set_global(pipe.F, pipe.FF, functools.reduce) 74 | ``` 75 | 76 | ## More 77 | 78 | No more ~ This library has less than ten lines of valid code, but it is very effective. 79 | 80 | If you like it, please give a Star. 😀 81 | 82 | This repository is released under the MIT.
