java - Configuring string externalization in Eclipse to use ${key} as field name -

-

suppose have simple code this:

public class externalizestringdemo {     public static void main(string[] args) {         system.out.println("hello world");     } }

now, want externalize greeting, perhaps facilitate internationalization/localization/etc. using eclipse, can use string externalization wizard (source/externalize strings), , configure this:

i can proceed wizard , propose these changes:

  • create file personal toys/src/messages.java
  • create file personal toys/src/messages.properties
  • edit externalizestringdemo.java
    • "hello world" becomes messages.getstring("demo_greeting")

my question simple: can ask eclipse externalize access use key field names instead? is, want access e.g. messages.demo_greeting.

note: if [substitution pattern] simple ${key}, generated code messages."demo_greeting", not valid java code.

if not possible, what's next best thing? (i'm thinking eclipse regex find/replace?).

eclipse has new string externalization mechanism this; uses own new message bundle instead of java's. need include org.eclipse.osgi….jar in project's build path use it.

help.eclipse.org - java development user guide > reference > wizards , dialogs > externalize strings wizard

  • use eclipse's string externalization mechanism
    • if unchecked standard externalization mechanism used, otherwise new eclipse string externalization mechanism used.
    • note: present if project build path contains org.eclipse.osgi.util.nls

the before-and-after shown in feature documentation:

old code:

public class myclass {    public void mymethod() {       string message;       ...       // no args       message = messages.getstring("key.one"); //$non-nls-1$       ...       // bind 1 arg       message = messageformat.format(           messages.getstring("key.two"),           new object[] {"example usage"}         ); //$non-nls-1$ //$non-nls-2$       ...    } }

new code:

public class myclass {    public void mymethod() {       string message;       ...       // no args       message = messages.key_one;       ...       // bind 1 arg       message = nls.bind(messages.key_two, "example usage"); //$non-nls-1$       ...    } }

(assuming mingw) i'm still trying handle on c++ stuff, after reading coun...
