===============
Acceptance Test
===============

If all links are valid, test is done successfully.


Directives
==========

A *directive* can be used to define the anchor point of a reference.
Index entries will point back to the *directive*.  If the item 
defined in the directive is not obtained from the source code, 
then define it here, like these.  All of these directives should 
have entries in an Index.

SPEC Macros
^^^^^^^^^^^

.. spec:def:: def_macro content

   :param arg: list of arguments is optional
   :type arg: str

   This is a standard SPEC macro definition.

.. spec:def:: def_function(arguments)

   :param str arguments: named argument(s) to this function

.. spec:rdef:: rdef_macro content

   This is a SPEC macro definition with symbols that are evaluated only at run-time.

.. spec:cdef:: cdef("cdef_macro", "content", "cdef_part", flags)

   :param str cdef_macro: one-word name (quoted string) for this macro chain
   :param str content: SPEC code to be inserted (typically a single macro)
   :param str cdef_part: name for this part of the chained macro
   :param str flags: see the manual
   
SPEC cdef macro definitions
++++++++++++++++++++++++++++++++

.. TODO: pull this subsection once this part is made to work

There are several different signatures for SPEC's ``cdef`` macro definition.
Here are some examples pulled from the ``SPEC.D`` directory.

.. note::  At present, the argument list from ``cdef`` macro definitions
   is not being parsed or handled.  This will be fixed in a future revision.

SPEC Variables
^^^^^^^^^^^^^^

These are some representative variable declarations in SPEC macro source files::

        global  BCDA_GM[]
        
           global    theta[]
           global    2theta[]  # this will not be found
           global    _motor[]
        
        global kohzu_PV kohzuMV_PV UND_PV Und_Off UNDE_TRACK_ON
        global       kohzuStop_PV kohzuMode_PV      kohzuMove_PV
            global CCD_OVERHEAD_SECS_MEASURED   # measured readout time
        
            global @A_name[] @B_name[]
               unglobal @A_name
               unglobal @B_name

Variables in Directives
+++++++++++++++++++++++

global variable declaration: 

.. spec:global:: A[]

   ``A[]`` contains the values of all motors

local variable declaration:  

.. spec:local:: i

   ``i`` is a local loop counter

array variable declaration: 

        tba

Variables in Roles
+++++++++++++++++++++++

* global variable declaration: :spec:global:`A[]`
* local variable declaration:  :spec:local:`i`
* array variable declaration: 

Python example
^^^^^^^^^^^^^^

.. py:function:: python_function(t = None)

   :param t: time_t object or None (defaults to ``now()``)
   :type  t: str


Roles
=====

A *role* refers to a *directive* (makes a link to a *directive* defined elsewhere).
Each of these items should produce a valid link.  Additionally, every call to a 
*role* should produce an index entry.

SPEC Macros
^^^^^^^^^^^

* macro definition: :spec:def:`def_macro`
* function definition: :spec:def:`def_function(arguments)`
* runtime-defined macro definition: :spec:rdef:`rdef_macro`
* chained macro definition: :spec:cdef:`cdef("cdef_macro", "content", "cdef_part", flags)`

SPEC Variables
^^^^^^^^^^^^^^

* global variable declaration: 
* local variable declaration: 
* array variable declaration: 

Python example
