GoStyle 2 | Go syntax implementation in Python. 3 | # Installation 4 | ``` 5 | pip install gostyle 6 | ``` 7 | # Threading Wrapper Like goRoutine 8 | In GoLang, we can create parallel tasks via keyword `go`: 9 | ```go 10 | //GoLang 11 | //... 12 | go XXXX(arg1,arg2) 13 | //... 14 | ``` 15 | In GoLang, the thread creating has following features: 16 | * The parameter passing is the same as the original function defined by user. 17 | * The original function is still usable as defined. 18 | 19 | However, in Python creating a thread is stupid: 20 | ```Python 21 | #Python 22 | #... 23 | t = threading.Thread(target=XXX, args=(arg1,arg2)) 24 | t.start() 25 | #... 26 | ``` 27 | ## Recommended Usage 28 | Usage with best compatibility: 29 | ```Python 30 | import time 31 | from gostyle import go, Chan 32 | chan1 = Chan() 33 | def test_thread(title:str): 34 | for cnt in range(10): 35 | chan1<=cnt 36 | time.sleep(1) 37 | print(title) 38 | def chan_reader(): 39 | while True : 40 | print(chan1()) 41 | # Start the thread 42 | go(test_thread)("Call") 43 | chan_reader() 44 | ``` 45 | 46 | ## How To Use Word `go` in Python 47 | If the function is self-defined, you can use decorator `@gostyle.startable()` like following: 48 | ```Python 49 | import time 50 | import gostyle 51 | @gostyle.startable() 52 | def test_thread(title:str): 53 | while True: 54 | time.sleep(1) 55 | print(title) 56 | # Start the thread 57 | test_thread.start("Start") 58 | # Note that the expression "test_thread('Normal')" can still run the original function in main thread. 59 | ``` 60 | 61 | Or, if the function is not a class/object method: 62 | ```Python 63 | import time 64 | import gostyle 65 | @gostyle.destination() 66 | def test_thread(title:str): 67 | while True: 68 | time.sleep(1) 69 | print(title) 70 | # Start the thread 71 | gostyle.to.test_thread("Go To Destination") 72 | # Note that the expression "test_thread('Normal')" can still run the original function in main thread. 73 | ``` 74 | 75 | Or: 76 | 77 | ```Python 78 | import time 79 | from gostyle import go 80 | @go.goable() 81 | def test_thread(title:str): 82 | while True: 83 | time.sleep(1) 84 | print(title) 85 | # Start the thread 86 | go.test_thread("Go") 87 | # Note that the expression "test_thread('Normal')" can still run the original function in main thread. 88 | ``` 89 | 90 | If the function is not self-defined(you can not add decorator to the function), or the function is a method of a class/object(the function you defined is hard to attach to "go"(same as "to") object in this package), you can use syntax like following: 91 | ```Python 92 | import time 93 | from gostyle import go 94 | def test_thread(title:str): 95 | while True: 96 | time.sleep(1) 97 | print(title) 98 | # Start the thread 99 | go(test_thread)("Call") 100 | ``` 101 | 102 | ## Run-Forever and Daemonize 103 | The `daemon` parameter controls the deamon option in package `threading`. and the forever parameter lets you get rid of a `while True:` expression in the function you defined. 104 | ```Python 105 | import time 106 | from gostyle import go 107 | def test_thread(title:str): 108 | # No Internal WHILE Here. 109 | time.sleep(1) 110 | print(title) 111 | # Start the thread 112 | go(test_thread, forever=True)("Call Forever") 113 | ``` 114 | 115 | ```Python 116 | import time 117 | import gostyle 118 | @gostyle.startable(forever=True) 119 | def test_thread(title:str): 120 | # No Internal WHILE Here. 121 | time.sleep(1) 122 | print(title) 123 | # Start the thread 124 | test_thread.start("Start Loop") 125 | ``` 126 | 127 | # Defer 128 | In GoLang, defer is used to do things(usually cleaning-up) after a function returns. 129 | ## How To Use in Python 130 | Usage of decorator `defer_inside`: 131 | ```Python 132 | from gostyle import defer_inside, defer 133 | @defer_inside 134 | def great_func(): 135 | a = [1,2,3] 136 | b = 8 137 | defer( 138 | lambda : a.append(7), 139 | lambda : print(a), 140 | lambda : print(b) 141 | ) 142 | a.append(9) 143 | return a,b 144 | print(great_func()) 145 | 146 | ``` 147 | 148 | 149 | 150 | ----------------------------------------- 151 | #
