[Pyzo] User defined alias in ipython profile not recognised

[Krishnan V]

Hi,
I use Pyzo for its speed and would like to thank the developers at the
outset.
I added an alias to ipython, saved it to the default profile file
~/.ipython/profile_default/ipython_config.py
It is a very simple alias really, just printing the file names instead of
all the information which ls gives.
If i launch ipython from command-line(anaconda prompt), the alias works.
From Spyder's ipython, the alias workds. unfortunately, from pyzo's
ipython, this does not. I have enabled "use ipython if available" option in
the shell configurations. There is only one python and this is windows.
Ipython: 6.2.1
pyzo: 4.5.0
python: 3.6.2
I wonder if this has something to do with pyzo, and can someone please help?
regards
Krishnan

Hi Krishnan,

I'm glad you like Pyzo!

I am not entirely sure if I understand it correctly. With alias do you
mean a Linux command alias?
Have you update the shell configuration to use this new command?
What kind of error message does the shell give you?

Regards,
  Almar

Hi,
thanks for your reply. i have used pyzo from its iep days also!
Ok, by alias i meant an ipython alias. let me elaborate a bit more. On
Windows, if i type ls on ipython, i get all listing inclding directory and
file sized. sometimes it is contributes to visual clutter. alias maps to
dir /on. So, on ipython i just created new alias by using command alias
vdir ls /b. now the problem is that when i close the session, this alias
is not persistent. and even if i keep the current terminal/session open but
if i open another session in parallel, this new alias does not appear
there. So, i want this alias to be "permanent". One way of achieving this
is to stick in the alias in the ipython config file. i create ipython
config default and in the ~/.ipython/default_config file, i stick in this
alias. So far so good. If i open the ipython from anaconda shell, i can
type this alias and get the expected outcome(file and directory names). But
if i open the ipython shell inside pyzo and type vdir, i get error:
<ipython-input-1-somestuff> in module()
--------->1 vdir
NameError: name 'vdir' not defined.

I was thinking if this is related to pyzo? Because ipython from terminal
and also from Spyder recognise this new alias i created. This ls and vdir
may be trivial usage and i still continue to use pyzo by typing ls or
remember to type alias everytime; or maybe have some init file. However, I
just want to check if there is something I am missing or something to do
with pyzo.
I hope this is clearer..?
Thank for response.

Krishnan

Ah! Thanks for clarifying. Top be fair, the IPython support in Pyzo is
not optimal (and I never use it myself).

The first thing that comes to mind is that perhaps the config file will
need to be loaded by Pyzo explicitly. You could try to see whether this
is the problem by raising an error in it (or make it syntactically
invalid) and then starting IPython and a Pyzo kernel and see what
happens. If the Pyzo kernel starts up normally, we know that there has
been no attempt to load the config file, and we should probably add that.

Regads,

Hello !
Yes ipython is slightly under utilised in pyzo but no complaints. I will
try what you suggested and report back. As of now i think it is the
problem as i put my alias in ipython config file. Another observation is
Ipython in pyzo cannot auto complete directories by hitting tab.
Which terminal do you use if not ipython?

Krishnan

Great!

Another observation is  Ipython in pyzo cannot auto complete

directories by hitting tab.

Yes, this is because Pyzo does not make use of IPython's autocompletion
mechanism.

Which terminal do you use if not ipython?

The standard OS prompt and Xonsh.
