Tomatsu sensei,
Some examples:
function print(s) System.out.println("" + s);
import java.io.*;
dir = new File("~/scripts/");
ext = ".pnut";
filter = new FileFilter(){
accept(file){
file.file && file.name.endsWith(ext);
}
}
for(f:dir.listFiles(filter)) //prints the file name without extension
print(`Fount a script called "` + f.name[0..f.name.length() - 6] +
`"`);
//I would prefer: print(`Fount a script called "` + f.name[0..-6] +
`"`);
for(f:dir.listFiles(filter)) //prints the file name without extension
print(`Fount a script called "` + f.name[0..-6] + `"`);
import java.util.jar.*;
jar = new JarFile("pnuts.jar");
for(f:jar.entries())
if(f.directory && f.name != "META-INF/") // != works on String,
very cool
print(f.name.replaceAll("/", ".")[0..f.name.length() - 2]);
// I would prefer : print(f.name.replaceAll("/", ".")[0..-2]);
It's just sugar to avoid calling ‘String.length() – x’ all the time.
Best,
Mike
