= Bolt Tutorial, Part I: Courses and Lessons =

== Creating a course ==

[ServerIntro Install the BOINC software] on a Linux system
(or run the [VirtualMachines BOINC server virtual machine] in a VMWare
player on any computer).

Use [MakeProject make_project] to create a BOINC project named "bolt_test":
{{{
> cd boinc/tools
> make_project --web_only bolt_test
}}}
Edit httpd.conf as directed (you'll need root access to do this).
Let's say your server's domain name is "a.b.c".

Visit http://a.b.c/test/create_account.php and create an account for yourself.

Visit http://a.b.c/test_ops/bolt_ops.php,
and create a course named "Test course"
with course document "course_doc.php" (we'll create this later).

== Lessons and sequences ==

Let's start with a simple course consisting of two lessons.
Each lesson consists of a PHP or HTML file.
Create the following files in ~/projects/test/html/user:

conifer_intro.php
{{{
<?php

echo "
Throughout California's Sierra Nevada mountains,
and especially at high altitudes,
the dominant plants are tall, straight
trees with narrow needle-like leaves.
These trees are called <b>conifers</b>
because they carry their seeds in cones.
<p>
This course will teach you how to identify
the most common types of California conifers.

";
?>

}}}

lesson2.html
{{{
This is the second lesson.
}}}

course_doc.php
{{{
<?php
return sequence(
    name('course'),
    lesson(
        name('lesson 1'),
        filename('lesson1.php')
    ),
    lesson(
        name('lesson 2'),
        filename('lesson2.html')
    )
);
?>
}}}

Diagramatically, the course structure is:

Now visit http://a.b.c/test/bolt.php.
You'll be asked to log in; do so.
Click on the button to start the test course.
You'll see:

Note that below your lesson Bolt has added some navigation links
and a form to ask questions.
Click on the "Next" button.
You'll see:

[[Image(lesson2.png, nolink)]]

Now suppose that instead of reading the lesson,
you go away (for an hour or a month) and return.
Simulate this by visiting http://a.b.c.test/bolt.php.
You'll see

[[Image(restart.png, nolink)]]

Notice that Bolt "remembers" where you are in the course
(this is stored in the database;
it will work even if you go to a different computer).

Now click "Resume", and you'll see the second lesson again.
Click on Next.
You'll see:

[[Image(finished.png, nolink)]]

Now visit http://a.b.c.test/bolt.php again,
and click on "History".
You'll see something like:

Bolt has recorded your course interactions and their timing,
in its database; this is used for course analytics (see part III of this tutorial).
