Question

I have a file called messages.properties which has lines with syntax <key>=<string>. Each key is unique but string isn’t. Many keys can have a same string. Also in the same folder I have some java classes which read the strings from messages.properties. They get string via the method Messages.getString("<key>"). So what I need to do is to convert Messages.getString("<key>") in java classes into "<key>" by reading their value from messages.properties. Here’s the sed onliner from @potong that does the trick.

sed 's|^\([^=]*\)=\(.*\)|[e-mail]("\1")@"\2"@g|;s/\\/\\\\/g' messages.properties |
sed -i -f - *.java

However the issue with this is it won’t work for some in messages.properties. How should I modify the script to solve this? Here’s a related question Search and replace with sed .

Sample messages.properties

Sting.1=Str
Sting.2=String
Sting.3=String
Sting.4=Strring
Sting.5=Str

Sample java class

System.Out.println(Messages.getString("Sting.1"));
System.Out.println(Messages.getString("Sting.2"));
System.Out.println(Messages.getString("Sting.3"));
System.Out.println(Messages.getString("Sting.4"));
System.Out.println(Messages.getString("Sting.5"));

Reqired java class

System.Out.println("Str");
System.Out.println("String");
System.Out.println("String");
System.Out.println("Strring");
System.Out.println("Str");

Answer 1

The actual problem was that eclipse split

Messages.getString("String.3")

into 2 lines,

    Messages
        .getString("String.3")

So this worked.

sed 's|^\([^=]*\)=\(.*\)|s@.getString("\1")@"\2"@g|;s/\\/\\\\/g' messages.properties |
sed -i -f - *.java
