The intenetion¶
ec - intends to reduce the learning curve needed to expose functionality via the command line. With available options like argparse and docopt, it might take several hours to get them right. And there is also the issue of the needed amount of extra coding to setup and process the arguments. See the following example to see how ec solves the issue.
A simple example¶
from ec.ec import task
@task
def say_hello():
print 'Hello, world!'
could be accessed from the command line, like:
$ python hello.py say_hello
Hello, world!
Features¶
- Typed arguments.
- Sub commands (like git).
- Custom types.
- Shell mode (like python’s interactive mode).
- Named / Positional arguments.
A more complete example¶
from: simple.py
from ec.ec import task, arg, group
@task # define a task
@arg(type=int, desc= 'Value for arg1') # add an argument with a type and a description
@arg(type=int)
def task1(arg1, arg2=1):
print arg1, arg2
@group(desc = 'A group with some tasks') # define a group
class group1:
@task
def task1(arg1): # define a task inside the group
print arg1 + arg1
Execute a task: <dispatch mode>
From the command-line enter
$ python simple.py task1 arg1=1 arg2=2
1 2
$ python simple.py group1/task1 arg1=1
2
$ python simple.py group1/task1 1 # positional arguments too are supported
2
Interactively execute tasks: <shell mode>
From the command-line enter
$ python simple.py # this will enter into ec-shell
>task1
Value for arg1: 1
arg2 (1): 2
1 2
>group1/task1 # execute task1 under group1
arg1: 1
11
>task1 arg1=1 # arguments can be given while calling the task, the missing arguments will be collected from the user
arg2 (1): 2
1 2
>^Z # exit the shell
