[jira] Created: (CONFIGURATION-395) groovy for interpolation and
expression engine
groovy for interpolation and expression engine
----------------------------------------------
Key: CONFIGURATION-395
URL: https://issues.apache.org/jira/browse/CONFIGURATION-395
Project: Commons Configuration
Issue Type: Improvement
Components: Expression engine, Interpolation
Reporter: ron
Priority: Minor
Currently the expression engine can be set but not the interpolation.
This patch proposes the ability to set a user specified interpolation engine.
It includes a groovy interpolation engine. Groovy comes naturally as an expressions and interpolation language in the java environment
API usage:
AbstractConfiguration c = new PropertiesConfiguration("conf/test.conf");
c.setInterpolator(new GInterpolator(c));
System.out.println(c.getString("test"));
Configuration examples:
library.path.1=${ if ("${System.getProperty{('os.name')}".toLowerCase().startsWith("windows")) "libw.dll"; else "libl" }
password=${println 'enter password'; readln}
I think that this is more feature rich than JEXL and is easier to use for java programmers.

Description:
Currently the expression engine can be set but not the interpolation.
This patch proposes the ability to set a user specified interpolation engine.
It includes a groovy interpolation engine. Groovy comes naturally as an expressions and interpolation language in the java environment
API usage:
AbstractConfiguration c = new PropertiesConfiguration("conf/test.conf");
c.setInterpolator(new GInterpolator(c));
System.out.println(c.getString("test"));
Configuration examples:
library.path.1=${ if ("${System.getProperty{('os.name')}".toLowerCase().startsWith("windows")) "libw.dll"; else "libl" }
password=${println 'enter password'; readln}
I think that this is more feature rich than JEXL and is easier to use for java programmers.

PS: I have added some more features:
I have extended this to enable caching and add custom imports.
thus in the example below query(..) will be executed only once.
custom imports can be predefined, so that they do not have to be included in the configuration.
API:
AbstractConfiguration c = new PropertiesConfiguration("conf/test.conf");
c.setInterpolator(new GInterpolator(c, true, new String[]{"util.Utils"}));
System.out.println(c.getString("password"));
System.out.println(c.getString("password"));
configuration example:
password=${Utils.query('enter password')}
