Batch processing

Within this project it’s possible to do all of the same things mentioned in the “Component” guide such as build a target executable with viash build and test a component with viash test. However, doing this for all components in the repository can bet quite tedious.

Luckily, Viash provides a set of commands for building, testing or inspecting all Viash components in the current namespace (ns).

Build all components

You can generate your first full development build using the viash ns build command.

viash ns build --setup cachedbuild

All 7 configs built successfully

Here are some useful optional arguments:

• --parallel: Run multiple builds in parallel.
• --setup cachedbuild: Build Docker images using the cachedbuild strategy.
• --query demo: Only select components that have ‘demo’ in the namespace or name.

Test all components

You can run all of the component tests using the viash ns test command.

Custom batch processing

The viash ns exec command can be used to run a command on every component.

viash ns exec "echo Hello {}"

Output

+ echo Hello /home/runner/work/website/website/guide/_viash_project_template/src/template/take_column/config.vsh.yaml
  Exit code: 0

  Output:
+ echo Hello /home/runner/work/website/website/guide/_viash_project_template/src/template/combine_columns/config.vsh.yaml
  Exit code: 0

  Output:
+ echo Hello /home/runner/work/website/website/guide/_viash_project_template/src/template/workflow/config.vsh.yaml
Hello /home/runner/work/website/website/guide/_viash_project_template/src/template/take_column/config.vsh.yaml

Hello /home/runner/work/website/website/guide/_viash_project_template/src/template/combine_columns/config.vsh.yaml

  Exit code: 0

Tips

Parallel builds

Some commands shown above can be optimized by adding the --parallel option:

• viash ns build --parallel will build in parallel
• viash ns test --parallel will test in parallel

For example:

viash ns test --parallel

Output

Subset to components or namespaces

In a development context, one often needs to rebuild one or a few components rather than the full repository. For this situation, viash ns has the option to specify query arguments: --query, query_name and query_namespace. We refer to the reference documentation for details and illustrate the use using an example:

viash ns build --query "^.*columns$"

Output

Exporting combine_columns (template) =docker=> /home/runner/work/website/website/guide/_viash_project_template/target/docker/template/combine_columns
Exporting combine_columns (template) =nextflow=> /home/runner/work/website/website/guide/_viash_project_template/target/nextflow/template/combine_columns
Not all configs built successfully
  3 configs were disabled
  2/2 configs built successfully

As shown here, the query arguments accept regular expressions.
