.. 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:: --spy
Print equivalent Python code before executing. For example::
=> (defn salutationsnm [name] (print (+ "Hy " name "!")))
def salutationsnm(name):
return print(((u'Hy ' + name) + u'!'))
=> (salutationsnm "YourName")
salutationsnm(u'YourName')
Hy YourName!
=>
.. versionadded:: 0.9.11
.. cmdoption:: --show-tracebacks
Print extended tracebacks for Hy exceptions.
.. versionadded:: 0.9.12
.. cmdoption:: -v
Print the Hy version number and exit.
.. _hyc:
hyc
---
Command line options
^^^^^^^^^^^^^^^^^^^^
.. cmdoption:: file[, fileN]
Compile Hy code to Python bytecode. For example, save the
following code as ``hyname.hy``:
.. code-block:: hy
(defn hy-hy [name]
(print (+ "Hy " name "!")))
(hy-hy "Afroman")
Then run:
.. code-block:: bash
$ hyc hyname.hy
$ python hyname.pyc
Hy Afroman!
.. _hy2py:
hy2py
-----
.. versionadded:: 0.10.1
