LoggingMagics.logstart(self, parameter_s='')
%logstart [-o|-r|-t|-q] [log_name [log_mode]]
If no name is given, it defaults to a file named 'ipython_log.py' in your current directory, in 'rotate' mode (see below).
'%logstart name' saves to file 'name' in 'backup' mode. It saves your history up to that point and then continues logging.
%logstart takes a second optional parameter: logging mode. This can be one of (note that the modes are given unquoted):
append
Keep logging at the end of any existing file.
backup
Rename any existing file to name~ and start name.
global
Append to a single logfile in your home directory.
over
Overwrite any existing log.
rotate
Create rotating logs: name.1~, name.2~, etc.
Options:
Since this marker is always the same, filtering only the output from a log is very easy, using for example a simple awk call
awk -F'#\[Out\]# ' '{if($2) {print $2}}' ipython_log.py
Start logging anywhere in a session.
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
