2021-11-02ccwl: Support external CWL workflows.Arun Isaac
* ccwl/ccwl.scm: Import (yaml). Export cwl-workflow?, cwl-workflow, cwl-workflow-file, cwl-workflow-inputs and cwl-workflow-outputs. (<cwl-workflow>): New type. (cwl-workflow, function-input-keys, function-outputs, function-object): New functions. (command-input-keys, command-object): Delete functions. (collect-steps): Replace command-object with function-object, command-input-keys with function-input-keys and command-outputs with function-outputs. * ccwl/cwl.scm (workflow->cwl-scm): Handle <cwl-workflow> objects. * tests/ccwl.scm ("read all forms of inputs and outputs from a CWL workflow"): New test. * guix.scm: Import (gnu packages guile-xyz) and (guix utils). (guile-libyaml): New variable. (ccwl)[inputs]: Add guile-libyaml.
2021-10-11ccwl: Factorize out CWL generation code to separate file.Arun Isaac
This factorization is required to support other compilation targets such as graphviz, bash, scheme, etc. * ccwl/cwl.scm: New file. * Makefile.am (SOURCES): Register it. * ccwl/ccwl.scm (ccwl): Export command?, command-inputs, command-outputs, command-args, command-stdin, command-other, workflow?, workflow-steps, workflow-inputs, workflow-outputs, workflow-other, input?, input-id, input-type, input-label, input-default, input-position, input-prefix, input-other, output?, output-id, output-type, output-binding, output-source, output-other, step?, step-id, step-run, step-in, step-out, unspecified-default?. (<workflow>): New type. (filter-alist): Move to cwl.scm. (make-workflow): Refactor into workflow->cwl-scm in cwl.scm. (output->cwl): Move to cwl.scm as output->cwl-scm. (command->cwl): Move to cwl.scm as command->cwl-scm. (workflow-steps): Rename to collect-steps. Clarify docstring. (workflow): Use collect-steps instead of workflow-steps. Explicitly pass empty list as other argument of make-workflow. Add TODO note to implement it properly. * scripts/ccwl.in: Import (ccwl cwl) instead of (ccwl yaml). Use workflow->cwl instead of scm->yaml. * tests/ccwl.scm ("stdin input should not have inputBinding"): Use command->cwl-scm from (ccwl cwl) instead of command->cwl from (ccwl ccwl).
