tcar_getConfigValue(1)
======================

== Name

tcar_getConfigValue - Standardize options retrieval from configuration
files.

== Synopsis

*tcar_getConfigValue FILE SECTION OPTION*

== Description

The *tcar_getConfigValue* function standardizes the way option values
are retrieved from configuration files. As convention,
*tcar_getConfigValue* uses the output produced by
*tcar_getConfigLines* as input to retrieve the option values. As
convention, in +option = "value"+ lines, the values retrieved are
always on the right side. The values retrieved are also output without
quotation and translation markers already expanded.

The *tcar_getConfigValue* function accepts the
following arguments:

FILE::
    This argument specifies the absolute path to the configuration
    file you want to retrieve the value from. For example,
    ``+${TCAR_WORKDIR}/Identity/Models/Themes/Default/Distro/5/Anaconda/branding.conf+''.

SECTION::
    This argument specifies the name of the section related to the
    configuration line you want to retrieve the value from. For
    example, ``symbols'' without brackets.

OPTION::
    This argument specifies the name of the option you want to
    retrieve the value from.

Use the *tcar_getConfigValue* function whenever you want to retrieve
values from configuration files in a controlled way.
