This release contains a number of big, incompatible changes compared to the previous release 0.1.1. The "guix process" command has been removed in favor of a single "guix workflow" command and workflows are now loaded from files instead of finding them in Guile modules on GUIX_WORKFLOW_PATH. Workflows can now be specified in Wisp syntax in addition to the S-expression Scheme syntax. For details see the section on changes below, or take a look at the manual: https://workflows.guix.info/manual/ =E2=80=A2 About 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. =E2=80=A2 Download Here are the compressed sources and a GPG detached signature[*]: https://ftpmirror.gnu.org/gwl/gwl-0.2.0.tar.gz https://ftpmirror.gnu.org/gwl/gwl-0.2.0.tar.gz.sig Use a mirror for higher download bandwidth: https://www.gnu.org/order/ftp.html [*] 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-0.2.0.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 BCA689B636553801C3C62150197A= 5888235FACAC and rerun the 'gpg --verify' command. This release was bootstrapped with the following tools: Autoconf 2.69 Automake 1.16.1 Gnulib v0.1-3269-g03d7a6b1f =E2=80=A2 Changes in 0.2.0 (since 0.1.1) ** Command line interface * Remove the =E2=80=9Cguix process=E2=80=9D command. * Remove GUIX_WORKFLOW_PATH; load workflows from files instead. * Add --container flag to enable process isolation ** Workflow syntax * Support Wisp syntax in workflow files. * Add syntactic sugar for defining workflows and processes. * Support syntax for procedures written in languages other than Guile. * Add graph syntax to specify process dependencies. * Add =E2=80=9Cauto-connect=E2=80=9D helper to automatically link up proc= ess inputs and outputs. * Deprecate the =E2=80=9Crestrictions=E2=80=9D field in workflow records = in favor of =E2=80=9Cauto-connect=E2=80=9D and =E2=80=9Cgraph=E2=80=9D synt= ax in the =E2=80=9Cprocesses=E2=80=9D field. * Fields of the =E2=80=9Cprocess=E2=80=9D form that expect lists now also= accept multiple values. * Add =E2=80=9Con=E2=80=9D procedure for application of higher-order func= tions to collections * Add =E2=80=9Cexpand=E2=80=9D procedure to expand variables in file name= templates ** Execution engines * Add simple execution engine and use it by default instead of the bash-e= ngine. ** Programming interface * Remove modules =E2=80=9C(guix processes)=E2=80=9D and =E2=80=9C(guix wo= rkflows)=E2=80=9D.
