Trash: Cookbook ipy_exportdb
Clone this wiki locally
Sometimes you have created a nifty macro you don't want to lose, or want to distribute to your friends. You can use ipy_exportdb.py extension for this.
Let's create a macro and an alias:
[d:/ipython]|13> a = 12 [d:/ipython]|14> print "a is ",a a is 12 [d:/ipython]|15> macro foo 13-14 Macro `foo` created. To execute, type its name (without quotes). Macro contents: a = 12 print "a is ",a [d:/ipython]|16> store foo Stored 'foo' (Macro) [d:/ipython]|17> alias bar hubba [d:/ipython]|18> store bar Alias stored: bar (0, 'hubba')
Now, we have it in our IPython database, but it's not really easy to distribute them to others. You can do this with ipy_exportdb:
[d:/ipython]|19> import ipy_exportdb [d:/ipython]|20> ipy_exportdb.export
This prints out the "export file" (which is legal python), the relevant portions of which are:
import IPython.ipapi ip = IPython.ipapi.get() # === Macros === ... ip.defmacro('foo', u'a = 12\n' u'print "a is ",a\n' ) ... # === Alias definitions === ... ip.defalias('bar', 'hubba') ...
You can also provide the output file name to exportdb().
The resulting file can be imported normally, e.g. in ipy_user_conf.py.
The following things are exported: macros, variables (basic data types only, i.e. no pickling), bookmarks, aliases, stored %env modifications.
