We are pleased to announce the release of the GNU Guix Workflow
Language version 0.5.0, representing 46 commits by two people,
incorporating the results of productive discussions among a number of
helpful people on the #guix and #guix-hpc IRC channels on libera.chat
and on the email@example.com mailing list.
This is a maintenance release with a number of bug fixes.
For details see the NEWS excerpt below.
The Guix Workflow Language (GWL) provides an extension to GNU Guix's
declarative language for package management to automate the
execution of programs in scientific workflows. The GWL can use
process engines to integrate with various computing environments.
See the manual for details:
Here are the compressed sources and a GPG detached signature[*]:
Use a mirror for higher download bandwidth:
[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg --verify gwl-0.5.0.tar.gz.sig
If that command fails because you don't have the required public key,
then run this command to import it:
gpg --keyserver keys.gnupg.net --recv-keys BCA689B636553801C3C62150197A5888235FACAC
and rerun the 'gpg --verify' command.
This release was bootstrapped with the following tools:
* Changes in 0.5.0 (since 0.4.0)
** Package handling
- Package specifications may also contain outputs.
- Integration tests verify that all examples from the documentation can be executed correctly.
- Integration tests include submission of jobs to a local Slurm cluster via DRMAA.
** Bug fixes
- Processes comparisons are now performed with an identity comparison.
This was always intended in cache table lookups, but the wrong
comparison procedure was used.
- Custom interpreters in code snippets would be miscompiled due to a
regression. =compile-procedure= was modified to address this
- With containerized execution, the contained script was not passed its
arguments for inputs, outputs, and values. Now the arguments are
- The container scripts were compiled with fixed values for process
inputs and outputs; now they read these values from their arguments as
in other execution modes.
- Set the job’s working directory when launching a DRMAA job.
