Discover Lino

Explore the demo projects

The Lino Book includes a collection of demo projects. We recommend to discover a few of them now.

• Initialize all demo projects in one operation by running inv prep in your copy of the book repository:

  $ go book
  $ inv prep
  

• To run the lino_book.projects.polly project:

  $ go polly
  $ pm runserver
  

We recommend to try the following demo projects:

• polly -- managing polls

• noi1r -- noi1e with React front end

• chatter -- an instance messaging system

• roger -- A customized Lino Voga site

Explore the standard plugin library

We recommend to look at least into the following pages:

• contacts : Managing contacts

• cal : Calendar

• comments : Letting users discuss

• ledger: General accounting

• courses : managing “activities”

These were only five of the many plugins that are part of Lino. Theoretically, all plugins are listed here:

• Plugin reference for end users

• Introduction to plugins

Exercise

Check the checkbox for each cell of the following table where the corresponding plugin is used by the corresponding project.

Plugin	noi1r	chatter	polly	roger
contacts	□	□	□	□
ledger	□	□	□	□
cal	□	□	□	□
comments	□	□	□	□
courses	□	□	□	□

Hint: modify and then run the following code snippet in order to see the answer

>>> from importlib import import_module
>>> import rstgen
>>> rows = []
>>> projects = ["noi1r", "chatter", "polly", "roger"]
>>> plugins = ("contacts", "ledger", "cal", "comments", "courses")
>>> for pname in plugins:
...     cells = [ pname ]
...     for prjname in projects:
...         settings_module = "lino_book.projects.{}.settings".format(prjname)
...         m = import_module(settings_module)
...         if not hasattr(m, "SITE"):
...             m = import_module(settings_module + ".demo")
...         # cells.append("yes" if m.SITE.is_installed(pname) else "no")
...         cells.append("?" if m.SITE.is_installed(pname) else "?")
...     rows.append(cells)
>>> header = ["Plugin"] + projects
>>> print(rstgen.table(header, rows))
