Smiley spies on your Python app while it runs
Project description
Smiley includes several subcommands for running Python programs and monitoring all of the internal details for recording and reporting.
Commands
The main program for Smiley is smiley. It includes several sub-commands.
run
Run an application and trace its execution.
monitor
Listen for trace data from an application running under the run command.
help
Get help for the smiley command or a subcommand.
Installing
Install with pip:
$ pip install smiley
Using
In one terminal window, run the monitor command:
$ smiley monitor
In a second terminal window, use smiley to run an application. This example uses test.py from the test_app directory in the smiley source tree.
$ smiley run ./test.py args: ['./test.py'] input = 10 Leaving c() [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] Leaving b() Leaving a()
The monitor session will show the execution path and local variables for the app.
