The Stratego/XT project distributes several packages. So let's first make clear what you actually need to install. Stratego/XT itself is a language independent toolset for constructing program transformation systems. Language-specific extensions of Stratego/XT are distributed as separate packages, so that you only have to install what you really need for your particular application.
Stratego/XT.
All Stratego/XT users need to install the ATerm Library
(aterm), the SDF2 Bundle
(sdf2-bundle) and Stratego/XT
(strategoxt). These packages enable you to
compile Stratego programs, and provide the basic
infrastructure for parsing and pretty-printing source files.
Stratego Shell. Optionally, you can install the Stratego Shell, which provides an interpreter for Stratego and an interactive command-line for experimenting with the Stratego language. The Stratego Shell is used in the Stratego part of this tutorial to demonstrate the features of the Stratego language. The Stratego Shell is also very useful for small experiments with strategies of the Stratego Library.
Extensions. Then there are the language-specific packages. These packages provide the basic infrastructure for parsing, pretty-printing, and in some cases also analyzing source files of a specific programming language. Reusing such a package enables you to get started immediately with the implementation of an actual transformation. Examples of such packages are Java-front, Dryad, Transformers C and C++, BibTeX Tools, Prolog Tools, AspectJ Front, and SQL Front. Also, there are some demonstration packages, for example Tiger Base, which implements a compiler for the Tiger language, and Java Borg, which demonstrates the implementation of language embeddings. All these packages can separately be installed as extensions of Stratego/XT.
Examples of the Stratego/XT Manual. All the code examples in this manual are available for separate download, so that you can experiment based on these: examples.tar.gz
First of all, you have to decide which deployment mechanism you want to use. For users of RPM-based Linux distributions (such as Redhat, Fedora Core, and SUSE), we advise to use RPMs, which are available from the release page. For Cygwin users we provide pre-compiled binaries that can simply be unpacked. For Mac OS X users, we provide these binary packages as well, but they can also use the Nix deployment system, which will guarantee that all dependencies are installed correctly. Nix packages are also available for Linux users. Finally, it is always possible to build from source.
Next, download the required packages. Stratego/XT depends on the
ATerm Library and the SDF2 Bundle, so you have to download
aterm, sdf2-bundle, and
strategoxt. The downloads are all available at the
release page of Stratego/XT.
The following sequence of commands takes care of building
and installing the aterm and the sdf2-bundle in
/usr/local.
$tar zxf aterm-version.tar.gz$cd aterm-version$./configure$make$make install$cd ..$tar zxf sdf2-bundle-version.tar.gz$cd sdf2-bundle-version$./configure$make$make install$cd ..
If you want to install the packages at a different
location (i.e. not /usr/local, you
should specify a --prefix in the configure
command. For example:
$./configure --prefix=/opt/aterm$./configure --prefix=/opt/sdf2-bundle --with-aterm=/opt/aterm
In this case, it possible that the sdf2-bundle cannot find
the aterm package. To tell the sdf2-bundle where it should
look for the ATerm Library, you can use the
--with-aterm argument:
$ ./configure --prefix=/opt/sdf2-bundle --with-aterm=/opt/aterm
Alternatively, you can add the location of the ATerm
Library to the PKG_CONFIG_PATH, which the
configure script will use for searching packages. In this
way, you don't need to specify the --with-
arguments. More information about this is available in the
pkg-config documentation (man
pkg-config). For example:
$ export PKG_CONFIG_PATH=/opt/aterm/lib/pkgconfig:/opt/sdf2-bundle/lib/pkgconfig
Unpack, configure, make and install Stratego/XT using the following commands:
$tar zxf strategoxt-version.tar.gz$cd strategoxt-version$./configure$make$make install
If you want to install StrategoXT at a different prefix,
you should specify a --prefix. If you
installed the ATerm Library and the SDF2 Bundle at a
different location, you should specify their location
using --with-aterm and
--with-sdf. For example:
$ ./configure --prefix=/opt/strategoxt \
--with-aterm=/opt/aterm --with-sdf=/opt/sdf2-bundle
As mentioned earlier, you can alternatively add the
location of the ATerm Library and the SDF2 Bundle to the
PKG_CONFIG_PATH, which the configure script
will use for searching packages.
The Stratego Shell, Java Front, Tiger Base and several other packages depend on Stratego/XT. For all these packages, you can use the following commands:
$tar zxfpackage-version.tar.gz$cdpackage-version$./configure$make$make install
For all these packages, you should use the
--with-aterm=,
dir--with-sdf=,
and
dir--with-strategoxt=
options if you installed these packages at non-standard
locations. Alternatively, you can extend the
dirPKG_CONFIG_PATH to include the locations of
the ATerm Library, SDF2 Bundle, and Stratego/XT.
Installing binary RPMs is very easy. Install the RPMs by
running rpm -i * in the directory where you
have downloaded the RPMs. Use the upgrade option rpm
-U * if you have already installed earlier versions
of RPMs for aterm, strategoxt or the sdf2-bundle. Of course
you can also install the RPMs one by one by specifying the
filenames of the RPMs.
Using the Nix deployment system for the installation of Stratego/XT is a good idea if you need to run multiple versions of Stratego/XT on the same system, if you will need to update other Stratego/XT related packages regularly, or if there is a problem with installation from source at your system. The Nix deployment system is designed to guarantee that the Stratego/XT that we are using on our system is exactly reproduced on your system. This basically guarantees that the installation will never fail because of missing dependencies or mistakes in the configuration.
The release page of all the packages refer to Nix packages
that can be installed using
nix-install-package.
