The lino package

The lino package is the main plugin used by all Lino applications, and the root for the subpackages that define core functionalites.

As a plugin it is added automatically to your INSTALLED_APPS. It defines no models, some template files, a series of django-admin commands, the core translation messages and the core help_texts.py file.


Contains Lino's core functionalities.


If you want to see which version of Lino you have, you can say "hello" to Lino:


A series of wrapper modules to encapsulate Lino's core functionalities.


lino.utils (the top-level module) contains a few often-used function for general use.


This package contains model mixins, some of which are heavily used by applications and the Lino Extensions Library.


Most of this package has been moved to lino_book.


The standard model library included with Lino.


Some extensions for Sphinx.


See The django-admin commands added by the lino plugin.


Start up Django and Lino.

Optional settings_module is the name of a Django settings module. If this is specified, set the DJANGO_SETTINGS_MODULE environment variable.

This is called automatically when a process is invoked by a django-admin command.

This is usually called in the initialization code snippet of a tested document.

If your doctest reports a failure of the following type:

Failed example:
Expected nothing
    Started /usr/lib/python3.10/doctest.py ... docs/specs/overview.rst (using lino_amici.projects.amici1.settings.demo) --> PID 217238

then it's because your project directory contains a log directory.

class lino.AppConfig(app_name, app_module)

Bases: AppConfig

This is the only django.apps.AppConfig object used by Lino. Lino applications instead use the lino.core.plugins.Plugin class to define plugins. See Introduction to plugins.

The lino_xl package

This package contains the code of the Lino Extensions Library.

See Plugins for the list of plugins.


These are the plugins included with Lino XL.

The lino_react package


A user interface for Lino applications that uses FaceBooks React JS framework.

The lino_book package

This is the code repository that contains (1) the Sphinx source files of the Lino Developer Guide, (2) the lino_book Python package and (3) a test suite with doctest-based tests for the Lino framework.

The Lino Developer Guide is the technical documentation tree of the Lino framework. It is visible on https://dev.lino-framework.org.

The lino_book Python package is a collection of small example Lino applications used for educational and testing purposes.

The code repositories for the lino and lino_xl Python packages have no documentation tree on their own and almost no unit tests, they are tested and documented here.

The lino_book package contains a set of example projects used both for testing and explaining Lino framework.

It is not published on PyPI because that would make no sense. You use it by cloning the repository from GitLab (which is done automatically by getlino configure with --devtools).


This package contains example applications included with the Lino book.
