.SH NAME test-tc.py
Test driver to exercise the \fCtconfpy\fP Python module.


.SH SYNOPSIS
test-tc.py [symtbl] [nonewvars] [templates] [temponly] [limitns] [litvars] [nopredefs] [debug] cfgfile, ...

.SH OPTIONS

.TP
.B symtbl

This option causes the test driver to include a symbol table with some
predefined test variables in it.  These are useful for experimenting
with variable dereferencing, substitution, and type/value enforcement.

The default is to not predefine any such variables. (Note that whether
this option is present or not, \fCtconfpy\fP always creates a number of
predefined variables of its own internally.  See the \fCtconfpy\fP
documentation for the details.)  

You can see all the predefined variables (and their attributes) by
running \fCtest-tc.py\fP on an empty configuration file.  This will
show you both the variables automatically defined by \fCtconfpy\fP as
well as any variables created with this option, if present.

.TP
.B nonewvars

This option disables the creation of new variables in the
configuration file (via the \fCAllowNewVars\fP API option).  The user
is limited to referencing and modifying only those variables already
present in the symbol table.  Typically used when passing an initial
symbol table to the parser to limit the user to only those variables.
The default is to permit new variable creation.

.TP
.B templates

This option creates a default set of variable templates for use in
the configuration file.  These are passed to the \fCtconfpy\fP parser
via the \fCTemplates={}\fP API option.

The following variable templates are predefined when this option
is used:

.ft C \" courier
.nf


Name    Val       RO Type    Def   Legal Values                 Min/Max
--------------------------------------------------------------------------

templb  1         RW boolean False []                           None None
templc  4+5j      RW complex 0-0j  [1-1j, 1+1j]                 None None
templf  1.0       RW float   0.5   [3.14, 2.73]                 None None
templi  1         RW int     0     [1, 2, 23]                   None None
templs  "stringy" RW string  ""    [r'^box$', r'^Bax', r'a+bc'] 3    8
.fi
.ft \" revert



.TP
.B temponly

This option will only permit new variable creation if a template for
that variable exists (via the \fCTemplatesOnly=True\fP parser API
option).  This is used in conjunction with the \fCtemplates\fP option
above.

.TP
.B limitns

This option will populate the initial symbol table so that only a
limited number of namespaces can be used.  If this option is present,
only the root namespace, and namespaces beginning with the string "NS"
will be allowed.  In this case, namespaces will be required to be from
3 to 8 characters long.  The default without this option is to allow
new namespaces to be used without restrictions on name or length.  The
initial namespace is set to root ("") whether or not this option is
selected.

.TP
.B litvars

By default, \fCtconfpy\fP does nothing to text encountered inside
of \fC.literal\fP blocks in a configuration file.  If this option
is present, the test driver tells \fCtconfpy\fP to replace any variable
references present in a \fC.literal\fP block.  See the \fCtconfpy\fP
documentation for a more complete description.

.TP
.B nopredefs
This option tells the parser (via the \fCReturnPredefs=False\fP API option)
to
.B not
include any of its own predefined variables in the symbol table it
returns.

.TP
.B debug

This option causes the test driver to invoke \fCtconfpy\fP with
debugging enabled and then display debug output when parsing is
complete.  The default is for debug output to be disabled.


.SH ADDING OR CHANGING PREDEFINED VARIABLES IN THE TEST DRIVER

This test driver uses a simple table-driven scheme for predefining
variables should you desire this feature.  This can be found near
the beginning of the \fCtest-tc.py\fP file.  All this should be
fairly self-explanatory once you understand the various variable
attributes recognized by \fCtconfpy\fP.  Edit this table as 
desired to create more variables or different attribute values
for your testing purposes.

The exact same scheme is used for predefining variable templates and
you can add/delete/change these to suit your own tastes in the same
way.

.SH OTHER
Requires Python 2.3 or later.

.SH BUGS AND MISFEATURES
The symbol table dump at the end of a program run could be formatted better.
