xontrib-commands

Useful xonsh-shell commands/alias/completer functions

Installation

To install use pip:

xpip install xontrib-commands
# or: xpip install -U git+https://github.com/jnoortheen/xontrib-commands

Usage

xontrib load commands

building alias

Use xontrib_commands.argerize:Command to build arger dispatcher for your functions. This will create a nice alias function with auto-completions support.

from xontrib_commands.argerize import Command

@Command.reg
def record_stats(pkg_name=".", path=".local/stats.txt"):
    stat = $(scc @(pkg_name))
    echo @($(date) + stat) | tee -a @(path)

• Directly passing the Arger instances is also supported.

from xontrib_commands.argerize import Arger, Command

arger = Arger(prog="tst", description="App Description goes here")

@arger.add_cmd
def create(name: str):
    """Create new test.

    :param name: Name of the test
    """
    print(locals())

@arger.add_cmd
def remove(*name: str):
    """Remove a test with variadic argument.

    :param name: tests to remove
    """
    print(locals())

Command.reg(arger)

Now a full CLI is ready
