I just wanted to mention some minor problems with IPython 0.11 running
on Python 2.6.4.
The first (and most important) issue is a bug (reported as bug 488061 on
If you use list=!command you get deprecation warnings because the popen
command is deprecated in favor of the subprocess module.
I have submitted a patch for this bug but until now of now it is unassigned.
The other issues are minor.
I would like tab autocomplete to behave the same way as the shell (e.g.
bash). The current behavior lists all files as options when I hit tab to
complete the name of the parent directory.
The current default of asking the user to list or not when to many files
are present violates the principle of minimal input that all unix
programs share (e.g. rm is default instead of rm -i) which slows down a
Also the distinction between two different types of behavior depending
on the number of files in a directory is confusing.
Furthermore when there are not so many files present and the completion
shows the list immedately it scrolls (the output of) your previous
commands off the screen (which means you often have to scroll back to
see their results).
I usually tend to have thousands of data files in my work directories
and so I have to type 'n' whenever I change directories which is quite
So in conclusion I would like tab to not complete past a '/' and only
list all possible completions with a second hit of the tab key.
The final issue is that the current IPython puts an empty line before
While this might improve readability in some cases more often it is a
waste of screen space.
In particular when using clear the first line of the terminal is blank.
I would prefer again to stick to the default of most shells and remove
the empty line.
Please take these remarks as mere suggestions.
In general I like IPython a lot and I hope to see it evolve into an ever
more useful tool.
