Print the sourcecode of a whole java project

Question

I have to print the whole sourcecode of a java-project. The final version should look like: Eclipse: File -> Print. But with this function you can only print one file at once.

Is there a way to print (or create a pdf/rtf of) the whole project (all *.java, *.xml, ... files) with one command?

Im using eclipse galileo on windows xp sp3

EDIT: For each class/file the page should (more or less) look like this:

C:\..\..\..\LibraryExtractor.java

1 package utils.libraries; 2 3 import java.io.File; 9 10 /** 11 * @ 12 * @ 13 * @ 14 */ 15 public class LibraryExtractor { 16 17 /** 18 *  19 *  20 * 21 *  22 *  23 * 24 * 25 */ 26 public static void extranctLibrary(String library, File targetFile) throws IOException, URISyntaxException { 27 targetFile.getParentFile().mkdirs(); 28 if (!targetFile.exists()) 29 targetFile.createNewFile(); 30 31 ClassLoader classLoader = LibraryExtractor.class.getClassLoader(); 32 InputStream in = classLoader.getResourceAsStream(library); 33 OutputStream out = new FileOutputStream(targetFile); 34 35 byte[] buf = new byte[1024]; 36 int len; 37 38 while ((len = in.read(buf)) > 0) 39 out.write(buf, 0, len); 40 41 in.close(); 42 out.close(); 43 } 44 } 45

SOLUTION:

1. enscript (with Cygwin)

2. Java2Html Eclipse-Plugin (only works with Europa)

Answer 1

If you don't mind installing Cygwin, or running on Linux, the following command will do what you want:

enscript -r -2 --file-align=2 --highlight --line-numbers -o - `find . -name '*.java'` | ps2pdf - files.pdf 

enscript is a program for converting text files to a variety of output formats; PostScript is the default, but you can also produce HTML, RTF, and a few others. The -r option says to print in landscape, -2 is two columns per page (save trees), --file-align=2 says that each new file should start on its own physical page, --highlight turns on language-specific syntax highlighting (it will try to figure out the language, or you can specify "java"), --line-numbers should be obvious, and -o - sends the output to standard-out (where it's piped to ps2pdf).

find generates the list of files; here I'm telling it to find all Java files under in the current directory. The output is passed as arguments to enscript; for "50-100 files" you should be OK, but you might need to read about xargs. You could get rid of the -name argument to generate a list of all files, or add multiple -name arguments to add more file types to the list; I wouldn't go with the "all files" approach, because then you'll get source-control files.

ps2pdf takes the PostScript output from enscript and converts it to PDF, which you can print.
