-----------------------------------
Summary: JupIOFactory and trimming of newline & carriage return
characters
Key: CONFIGURATION-737
URL: https://issues.apache.org/jira/browse/CONFIGURATION-737
Project: Commons Configuration
Issue Type: Bug
Components: Expression engine
Affects Versions: 2.4
Reporter: Chris
I want to configure the line separator that should be used in my output via
config file.
E.g. using the property
L1=\n
and JupIOFactory as following:
{quote}{{public static Configuration loadConfig(String fileName) throws
ConfigurationException {}}
{{ Parameters params = new Parameters();}}
{{ PropertiesBuilderParameters properties = params.properties();}}
{{ properties.setFileName(fileName)}}
{{ .setThrowExceptionOnMissing(true)}}
{{ .setIOFactory(new PropertiesConfiguration.JupIOFactory())}}
{{ .setListDelimiterHandler(new DefaultListDelimiterHandler(','));}}
{{ FileBasedConfigurationBuilder<FileBasedConfiguration> builder =}}
{{ new
FileBasedConfigurationBuilder<FileBasedConfiguration>(PropertiesConfiguration.class)}}
{{ .configure(properties}}
{{ );}}
{{ Configuration config = builder.getConfiguration();}}
{{ return config;}}
{{ }}}
{quote}
The value of the property gets trimmed. Java Properties (JDK 8) does not trim
newline and carriage return characters.
The problem seems to arise in the method at the following code part
(DefaultListDelimiterHandler - where the string gets trimmed):
{quote}{{protected Collection<String> splitString(final String s, final boolean
trim)}}
...
{{// Add last token}}
{{ String t = token.toString();}}
{{ if (trim)}}
{{ {}}
{{ t = t.trim();}}
{{ }}}
{{ list.add(t);}}
{quote}
