The current version of Storm is
0.5.21, released on 2022-11-13. Only the latest release is
provided in binary form. Earlier releases have to be compiled from source. All releases are marked
in the Git repository by a tag with the name
Release notes for each release are found here or in the annotated release tags in the Git repository.
To run the compiler, simply unpack the archive file and run
Storm.exe on Windows), and
the top loop for Basic Storm should start. For more detailed instructions, see
For Windows, no external libraries are required (except for
dbghelp.dll, which is included with
Windows). The Ui library requires Windows 7 or later.
For Linux, the C standard library for GCC 8.3.0 or later is required. For the Ui library, Gtk+ 3.10
or later is required.
libjpeg are also required for proper image decoding, but they
are included in the download since there are many incompatible versions of these libraries.
Storm is available with two different garbage collectors. The default garbage collector (used above) is MPS, which is performant and stable. The other alternative is SMM (Storm Memory Manager) which is currently in the experimental stage.
These releases use the Memory Pool System from Ravenbrook Ltd. for memory management. The Memory Pool System is very stable and performant.
These releases use the Storm Memory Manager for memory management, which is a homegrown garbage collector for Storm. The SMM generally performs worse compared to the Memory Pool System (approximately 2-3x runtimes when using the MPS, and occasionally longer pause times), and it is not as mature as the MPS.
This option is currently experimental, but seems to work well in many cases. It is slower than the MPS garbage collector.
The source code (licensed under GNU LGPL version 2.1) is freely available through Git at the following URL:
git clone git://storm-lang.org/storm.git
The repository has a few submodules. To fetch them as well, execute the following commands inside the repository:
git submodule init
git submodule update
If you get an error about an unreachable submodule, don't worry. That repository only contains some test data for the language server which is not required.
To build Storm, you need
mymake, available at GitHub or
git://storm-lang.org/mymake.git. When you have installed mymake, compiling Storm is just
to make a release build. During development, use
mm Main or
mm Test to build the
development version of the main entry point and the test suite respectively. Mymake is available as
a package in Debian (testing) as well.
To specify which garbage collector to use, either edit
Gc/Config.h, or compile storm with
mm mps Main or
mm smm Main.
On Linux (Debian), the following packages need to be installed to successfully compile Storm, in addition to Mymake and GCC:
libgtk-3-devGtk+ 3 headers
libturbojpeg-devHeaders for JPEG decoding
libpng-devHeaders for PNG decoding
libopenal-devOpenAL headers for sound output
libtoolBuild-tools required for building a custom Cairo
These are not required on Windows, as Storm relies on the corresponding functionality in the Windows API instead of separate libraries.
Storm is licensed under the LGPL version 2.1. Note, however, that the MPS release uses the Memory Pool System from Ravenbrook Ltd. which has a separate license (BSD 2-clause license). The SMM is licensed under the LGPL version 2.1, just like Storm.
Parts of the libraries, such as the Ui library, may rely on other third party libraries. To check
which libraries are used and which licenses apply, type
licenses in the Basic Storm top loop, or
core.info.licenses from your code. Note that this only shows loaded libraries. You might want
to use the library you are interested in (e.g. by typing
help ui) to make sure they are loaded
before querying the license information.
