From 63d5be91462d897d8fb37b31802dab464d879c87 Mon Sep 17 00:00:00 2001 From: Todd Leonhardt Date: Wed, 14 Jun 2017 20:03:05 -0400 Subject: Updated documentation and examples Added information related to the new pyscript command. The old way of running Python scripts via "py run()" should be considered deprecated. The new "pyscript" command is superior in two significant ways: 1) It supports tab-completion of file system paths 2) It allows the user to pass command-line arguments to scripts --- examples/script_conditional.py | 35 ++++++++++++++++++++++------------- 1 file changed, 22 insertions(+), 13 deletions(-) (limited to 'examples/script_conditional.py') diff --git a/examples/script_conditional.py b/examples/script_conditional.py index f0ded920..c26bd5fe 100644 --- a/examples/script_conditional.py +++ b/examples/script_conditional.py @@ -4,27 +4,36 @@ This is a Python script intended to be used with the "python_scripting.py" cmd2 To run it you should do the following: ./python_scripting.py - py run('script_conditional.py') + pyscript script_conditional.py directory_path Note: The "cmd" function is defined within the cmd2 embedded Python environment and in there "self" is your cmd2 application instance.
