The quote_char is used to quote the entire setting when it is modified
as a result of changes to some subsettings.
For an example let's assume we have a setting of this form:
JAVA_ARGS=-Xmx256m
and we want to add the '-Xms' parameter to the setting, for that purpose
we define a resource like this:
ini_subsetting { '-Xms':
ensure => present,
path => '/some/config/file',
section => '',
setting => 'JAVA_ARGS',
subsetting => '-Xms'
value => '256m',
}
which results into the following setting:
JAVA_ARGS=-Xmx256m -Xms256m
But this is not what we intended - if this setting is read by the bash
shell the '-Xms256m' parameter is interpreted as a command to be
executed rather than a value to be assigned to the JAVA_ARGS variable.
To fix this problem the quote_char parameter was added to the
ini_subsetting resource type, and we'll take advantage of it to fix the
problem in the above example like so:
ini_subsetting { '-Xms':
ensure => present,
path => '/some/config/file',
section => '',
setting => 'JAVA_ARGS',
quote_char => '"',
subsetting => '-Xms'
value => '256m',
}
which will result into:
JAVA_ARGS="-Xmx256m -Xms256m"
which is what we intended.
