%Store eliminated in configuration and magic commands in 0.11

[excetara2]

I had used in console the store command to store macros for multiple sessions. I noticed this has been removed in the console and in qtconsole in 0.11. I haven't seen anything to store macros persistently across sessions so I am guessing this is a regression that should have made it into 0.11 but didn't for one reason or another.

We do intend to restore %store or something equivalent before the next release, I think.

[excetara2]

That'd be great. Is there anything similar one can do now to keep macros between sessions. Like a function to declare a macro that could be loaded on ipython startup.

Cheers,
Jeff

If you use the new config files, and find exec_lines, you can store the code in a string and call %macro, something like this:

...exec_lines = ["""mymacrocode = "print 'Hello world!'" """,
                       """%macro mymacro mymacrocode"""]

I haven't tested this, but it should work. I don't think there's a way to interactive store a macro, though.

[excetara2]

Thanks for that. I'll check it in the next couple days if that will work
and maybe just write a python function to automate that if it works. I
really don't have that many macros just a couple that I would like to
have stored.

I used store a lot. Guess I'm going back to the old ipython for now.

[excetara2]

It is not that bad without it I realized because saves multiline
commands. It searches back through the multi-line commands quickly but
store would still be nice to have.

Sorry no-one's got round to bringing it back yet. If either of you would like to work on it, you'll need to update the quarantined pspersistence module to the new API. Its current code is here:

https://github.com/ipython/ipython/blob/master/IPython/quarantine/pspersistence.py

We can of course provide more information if you want to ask questions on the mailing list.

[excetara2]

Where is the relevant info on the new API? Seems like it shouldn't be
that difficult. If I get time soon, I'll have a go at it.

Cheers

I'm not sure if there is a neat source for what changed, unfortunately. At a brief glance, I think the only thing that changes is how we register magics. Have a look at how it's done for history: https://github.com/ipython/ipython/blob/master/IPython/core/interactiveshell.py#L1875

Also, if you're interested in persistence, I wrote down a few thoughts about what we might do in the future. In particular, using dill (an extension to pickle) might be interesting, because we could store objects like functions which we can't currently.

[excetara2]

I'll have a look. Thanks.

Great, thanks.

To explain a bit more about the initialisation: in the old design, modules
would use ipapi.get() to retrieve the single instance of the
InteractiveShell. The aim is to move InteractiveShell away from being a
singleton (although it still is for now). So modules should have a hook
which gets called as the InteractiveShell is being set up (e.g. extension
modules have a load_ipython_extension hook:
http://ipython.org/ipython-doc/stable/config/extensions.html ).

[takluyver]

%store is now back in an extension for 0.12. To load it, do %load_ext storemagic. To have it always loaded, add 'storemagic' to the list c.InteractiveShellApp.extensions in your ipython_config.py file.

[excetara2]

Sorry!! For some reason it didn't work at first try for storing macros that were defined but restarted and now it's a go. THANKS FOR THE HARD WORK!!!!!!

[takluyver]

You're welcome. Let me know if you can replicate any problems with it.

I should probably check the documentation, I didn't look at updating any of
it.

[excetara2]

I think the documentation appears to be good. I just had forgot that it stores the macro as a variable. Then the variable can be stored.
