SphinxTrain::Config - Configuration management for Sphinx Training
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use SphinxTrain::Config;
|
|
# -cfg specifies the default configuration if nothing was passed on the command-line
|
|
use SphinxTrain::Config -cfg => "./etc/sphinx_train.cfg";
|
|
# -ns specifies the namespace to load the configuration file in
|
|
use SphinxTrain::Config -pkg => 'ST';
|
|
# $ST::CFG_FOO is now defined
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This module evaluates sphinx_train.cfg in a dedicated package, writes
|
|
sphinx_train.resolved.json, and loads all variables into ST:: from that file.
