Command Line Options
|
|
^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. cmdoption:: -c <command>
|
|
|
|
Execute the Hy code in *command*.
|
|
|
|
.. code-block:: bash
|
|
|
|
$ hy -c "(print (+ 2 2))"
|
|
4
|
|
|
|
.. cmdoption:: -i <command>
|
|
|
|
Execute the Hy code in *command*, then stay in REPL.
|
|
|
|
.. cmdoption:: -m <module>
|
|
|
|
Execute the Hy code in *module*, including ``defmain`` if defined.
|
|
|
|
The :option:`-m` flag terminates the options list so that
|
|
all arguments after the *module* name are passed to the module in
|
|
``sys.argv``.
|
|
|
|
.. versionadded:: 0.11.0
|
|
|
|
.. cmdoption:: --spy
|
|
|
|
Print equivalent Python code before executing in REPL. For example::
|
|
|
|
=> (defn salutationsnm [name] (print (+ "Hy " name "!")))
|
|
def salutationsnm(name):
|
|
return print(((u'Hy ' + name) + u'!'))
|
|
=> (salutationsnm "YourName")
|
|
salutationsnm(u'YourName')
|
|
Hy YourName!
|
|
=>
|
|
|
|
`--spy` only works on REPL mode.
|
|
.. versionadded:: 0.9.11

(defn hy-hy [name]
|
|
(print (+ "Hy " name "!")))

Then run:
|
|
