Creating Packages with setup.rb

Creating Single Package Archive

"Single Package Archive" means the archive which includes only one PACKAGE. "package" means one set of ruby scripts, ruby extentions, commands, and data files.

setup.rb requires that the archive is structured like this:

PackageTop/
    setup.rb
    lib/
        (ruby scripts)
    ext/
        (ruby extentions)
    bin/
        (commands)
    data/
        (data files)

Each file/directories acts as below:

setup.rb

The installer. This file is included in this archive. Just copy it to your package.

lib/, bin/, data/

These directories includes data files which are to be installed. This directory tree is mirrored to the target directory, from lib/ to RUBYLIB/, from bin/ to BINDIR/, from ext/ to RUBYLIB/ARCH/ ....

Use lib/ for ruby scripts, bin/ for commands, data/ for any other data files.

ext/

ext/ directory includes ruby extentions. If you want to install RUBYLIB/ARCH/someext.so, create a directory ext/someext/ and put source files into it.

[WARNING] All extention source directories MUST include the file "MANIFEST". setup.rb will complies directries only if the directries contains MANIFEST.

Creating Multi-Package Archive

setup.rb can handle an archive which includes multiple PACKAGEs.

setup.rb requires the archive is structured as below:

PackageTop/
    setup.rb
    packages/         <--- fixed name
        tmail/        <--- tmail package
	    bin/
	    lib/
	    ext/
	    data/
        raccrt/       <--- raccrt package
	    bin/
	    lib/
	    ext/
	    data/
        strscan/      <--- strscan package
	    bin/
	    lib/
	    ext/
	    data/
        amstd/        <--- amstdd package
	    bin/
	    lib/
	    ext/
	    data/

Hooking Tasks

You can hook any tasks, such as "config" "setup". For example, you want to make some files in lib/tmail/ when setup. Then create file lib/tmail/pre-setup.rb and put this:

# pre-setup.rb

# process grammer file
system "racc #{srcdir_root + '/src/mp.y'} -o mailp.rb"

# require all ruby scripts in this directory from _loadlib.rb.
list = Dir.glob(curr_srcdir + '/*.rb').collect {|n| File.basename(n) }
File.open( '_loadlib.rb', 'w' ) {|f|
  f.puts list.collect {|n| "require 'tmail/" + n + "'" }
}
File.open( '../tmail.rb', 'w' ) {|f|
  f.puts "require 'tmail/_loadlib'"
}

This file is evaluated on task "setup" in the directory, before processing any other thing. Acceptable hook file name is:

{pre,post}-{config,setup,install,clean}.rb

[NOTE] You can also put hook files in the top directory of archive and/or the type-root directory (bin/, lib/,...).

srcdir/objdir support

setup.rb supports srcdir/objdir separation. In other words, you can compile everything out of the source directory.

If you write hooks, you should supports srcdir/objdir system. When you read source code, read it from srcdir. When you write anything, write it to the current directory. There's also some APIs to help your work. see Hook Script APIs Reference Manual

metaconfig

You can add new config options by writing file "metaconfig". metaconfig must be placed in the package-root directory.

Here is a simple example of metaconfig.

add_path_config 'libc', '/lib/libc.so', 'path to the C standard library'
add_bool_config 'win32', false, 'compile with Win32 support'

This script defined new config option --libc and --win32.

In metaconfig, you can use some APIs described in metaconfig API Reference Manual

Backward Compatibility

I do not assure any backward compatibility for the setup.rb. If you'd like old behavior, just use old version.

License

GNU Lesser General Public License (LGPL) version 2. For details, see file "LGPL".

NOTE: You CAN distribute your program under the any licenses you like. LGPL does not force you to make your programs LGPL while the installer is LGPLed one.

Installation Manual

You can freely copy/edit and/or distribute Usage_*.txt files which are included in this archive. I do not claim any rights on them. Removing my copyright is also OK.
