Xml format of conditional module [xmodule]
**********************************************
.. module:: conditional_module
Format description
==================
The main tag of Conditional module input is:
.. code-block:: xml
<conditional> ... </conditional>
``conditional`` can include any number of any xmodule tags (``html``, ``video``, ``poll``, etc.) or ``show`` tags.
conditional tag
---------------
The main container for a single instance of Conditional module. The following attributes can
be specified for this tag::
sources - location id of required modules, separated by ';'
[message | ""] - message for case, where one or more are not passed. Here you can use variable {link}, which generate link to required module.
[submitted] - map to `is_submitted` module method.
(pressing RESET button makes this function to return False.)
[correct] - map to `is_correct` module method
[attempted] - map to `is_attempted` module method
[poll_answer] - map to `poll_answer` module attribute
[voted] - map to `voted` module attribute
show tag
--------
Symlink to some set of xmodules. The following attributes can
be specified for this tag::
sources - location id of modules, separated by ';'
Example
=======
Examples of conditional depends on poll
-------------------------------------------
.. code-block:: xml
<conditional sources="i4x://MITx/0.000x/poll_question/first_real_poll_seq_with_reset" poll_answer="man"
message="{link} must be answered for this to become visible.">
<html>
<h2>You see this, cause your vote value for "First question" was "man"</h2>
</html>
</conditional>

####################################
CustomResponse XML and Python Script
####################################
This document explains how to write a CustomResponse problem. CustomResponse
problems execute Python script to check student answers and provide hints.
There are two general ways to create a CustomResponse problem:
*****************
Answer tag format
*****************
One format puts the Python code in an ``<answer>`` tag:
.. code-block:: xml
<problem>
<p>What is the sum of 2 and 3?</p>
<customresponse expect="5">
<textline math="1" />
</customresponse>
<answer>
# Python script goes here
</answer>
</problem>
The Python script interacts with these variables in the global context:
* ``answers``: An ordered list of answers the student provided.
For example, if the student answered ``6``, then ``answers[0]`` would
equal ``6``.
* ``expect``: The value of the ``expect`` attribute of ``<customresponse>``
(if provided).
* ``correct``: An ordered list of strings indicating whether the
student answered the question correctly. Valid values are
``"correct"``, ``"incorrect"``, and ``"unknown"``. You can set these
values in the script.
* ``messages``: An ordered list of message strings that will be displayed
beneath each input. You can use this to provide hints to users.
For example ``messages[0] = "The capital of California is Sacramento"``
would display that message beneath the first input of the response.
* ``overall_message``: A string that will be displayed beneath the
entire problem. You can use this to provide a hint that applies
to the entire problem rather than a particular input.
Example of a checking script:
.. code-block:: python
if answers[0] == expect:
correct[0] = 'correct'
overall_message = 'Good job!'
else:
correct[0] = 'incorrect'
messages[0] = 'This answer is incorrect'
overall_message = 'Please try again'
**Important**: Python is picky about indentation. Within the ``<answer>`` tag,
you must begin your script with no indentation.
*****************
Script tag format
*****************
The other way to create a CustomResponse is to put a "checking function"
in a ``<script>`` tag, then use the ``cfn`` attribute of the
``<customresponse>`` tag:
.. code-block:: xml
<problem>
<p>What is the sum of 2 and 3?</p>
<customresponse cfn="check_func" expect="5">
<textline math="1" />
</customresponse>
<script type="loncapa/python">
def check_func(expect, ans):
# Python script goes here
</script>
</problem>
**Important**: Python is picky about indentation. Within the ``<script>`` tag,
the ``def check_func(expect, ans):`` line must have no indentation.
The check function accepts two arguments:
* ``expect`` is the value of the ``expect`` attribute of ``<customresponse>``
(if provided)
* ``answer`` is either:
* The value of the answer the student provided, if there is only one input.
* An ordered list of answers the student provided, if there
are multiple inputs.
There are several ways that the check function can indicate whether the student
succeeded. The check function can return any of the following:
* ``True``: Indicates that the student answered correctly for all inputs.
* ``False``: Indicates that the student answered incorrectly.
All inputs will be marked incorrect.
* A dictionary of the form: ``{ 'ok': True, 'msg': 'Message' }``
If the dictionary's value for ``ok`` is set to ``True``, all inputs are
marked correct; if it is set to ``False``, all inputs are marked incorrect.
The ``msg`` is displayed beneath all inputs, and it may contain
XHTML markup.
* A dictionary of the form
.. code-block:: xml
{ 'overall_message': 'Overall message',
'input_list': [
{ 'ok': True, 'msg': 'Feedback for input 1'},
{ 'ok': False, 'msg': 'Feedback for input 2'},
... ] }
The last form is useful for responses that contain multiple inputs.
It allows you to provide feedback for each input individually,
as well as a message that applies to the entire response.
Example of a checking function:
.. code-block:: python
def check_func(expect, answer_given):
check1 = (int(answer_given[0]) == 1)
check2 = (int(answer_given[1]) == 2)
check3 = (int(answer_given[2]) == 3)
return {'overall_message': 'Overall message',
'input_list': [
{ 'ok': check1, 'msg': 'Feedback 1'},
{ 'ok': check2, 'msg': 'Feedback 2'},
{ 'ok': check3, 'msg': 'Feedback 3'} ] }
The function checks that the user entered ``1`` for the first input,
``2`` for the second input, and ``3`` for the third input.
It provides feedback messages for each individual input, as well
as a message displayed beneath the entire problem.

Formula Equation Input
######################
Tag: ``<formulaequationinput />``
The formula equation input is a math input type used with Numerical and Formula
responses only. It is not to be used with Symoblic Response. It is comparable
to a ``<textline math="1"/>`` but with a different means to display the math.
It lets the platform validate the student's input as she types.
This is achieved by periodically sending the typed expression and requesting
its preview from the LMS. It parses the expression (using the same parser as
the parser it uses to eventually evaluate the response for grading), and sends
back an OK'd copy.
The basic appearance is that of a textbox with a preview box below it. The
student types in math (see note below for syntax), and a typeset preview
appears below it. Even complicated math expressions may be entered in.
For more information about the syntax, look in the course author's
documentation, under Appendix E, the section about Numerical Responses.
Format
******
The XML is rather simple, it is a ``<formulaequationinput />`` tag with an
optional ``size`` attribute, which defines the size (i.e. the width) of the
input box displayed to students for typing their math expression. Unlike
``<textline />``, there is no ``math`` attribute and adding such will have no
effect.
To see an example of the input type in context:
.. code-block:: xml
<problem>
<p>What base is the decimal numeral system in?</p>
<numericalresponse answer="10">
<formulaequationinput />
</numericalresponse>
<p>Write an expression for the product of R_1, R_2, and the inverse of R_3.</p>
<formularesponse type="ci" samples="R_1,R_2,R_3@1,2,3:3,4,5#10" answer="R_1*R_2/R_3">
<responseparam type="tolerance" default="0.00001"/>
<formulaequationinput size="40" />
</formularesponse>

.. code-block:: xml
<poll_question> ... </poll_question>
``poll_question`` can include any number of the following tags:
any xml and ``answer`` tag. All inner xml, except for ``answer`` tags, we call "question".
poll_question tag
-----------------
Xmodule for creating poll functionality - voting system. The following attributes can
be specified for this tag::
name - Name of xmodule.
[display_name| AUTOGENERATE] - Display name of xmodule. When this attribute is not defined - display name autogenerate with some hash.
[reset | False] - Can reset/revote many time (value = True/False)
answer tag
----------
Define one of the possible answer for poll module. The following attributes can
be specified for this tag::
id - unique identifier (using to identify the different answers)
Inner text - Display text for answer choice.
