Important
This documentation covers IPython versions 6.0 and higher. Beginning with version 6.0, IPython stopped supporting compatibility with Python versions lower than 3.3 including all versions of Python 2.7.
If you are looking for an IPython version compatible with Python 2.7, please use the IPython 5.x LTS release and refer to its documentation (LTS is the long term support release).

- HistoryAccessor.connection_options¶
Options for configuring the SQLite connection
These options are passed as keyword args to sqlite3.connect when establishing database connections.
- Trait type:
Dict
- HistoryAccessor.enabled¶
enable the SQLite history
set enabled=False to disable the SQLite history, in which case there will be no stored history, no SQLite connection, and no background saving thread. This may be necessary in some threaded environments where IPython is embedded.
- Trait type:
Bool
- Default:
True
- HistoryAccessor.hist_file¶
Path to file to use for SQLite history database.
By default, IPython will put the history database in the IPython profile directory. If you would rather share one history among profiles, you can set this value in each, so that they are consistent.
Due to an issue with fcntl, SQLite is known to misbehave on some NFS mounts. If you see IPython hanging, try setting this to something on a local disk, e.g:
ipython --HistoryManager.hist_file=/tmp/ipython_hist.sqlite
you can also use the specific value
:memory:
(including the colon at both end but not the back ticks), to avoid creating an history file.- Trait type:

Options for configuring the SQLite connection
These options are passed as keyword args to sqlite3.connect when establishing database connections.

- MagicsManager.auto_magic¶
Automatically call line magics without requiring explicit % prefix
- Trait type:
Bool
- Default:
True
- MagicsManager.lazy_magics¶
Mapping from magic names to modules to load.
This can be used in IPython/IPykernel configuration to declare lazy magics that will only be imported/registered on first use.
For example:
c.MagicsManager.lazy_magics = { "my_magic": "slow.to.import", "my_other_magic": "also.slow", }
On first invocation of
%my_magic
,%%my_magic
,%%my_other_magic
or%%my_other_magic
, the corresponding module will be loaded as an ipython extensions as if you had previously done%load_ext ipython
.Magics names should be without percent(s) as magics can be both cell and line magics.
Lazy loading happen relatively late in execution process, and complex extensions that manipulate Python/IPython internal state or global state might not support lazy loading.
