Viash 0.5.7

Argument examples need to be of the same type as the argument itself

New Release

What’s new?

Examples for arguments now need to be of the same type as the argument itself. You can’t provide an integer for a string-based argument for example.
A handy new command has been added: viash config inject. This can be used to inject a Viash header into a script based on the arguments of the config file.

There have been some improvements to the Docker platform as well.
You can now add yum packages as a requirement:

platforms:
  - type: docker
    image: bash:latest
    setup:
      - type: yum
        packages: [ wget ]

You can now include ADD and COPY instructions in the config file:

platforms:
  - type: docker
    image: bash:latest
    setup:
      - type: docker
        add: [ "http://foo.bar ." ]

Full changelog

BREAKING CHANGES

  • viash config: An argument’s example now needs to be of the same type as the argument itself. For example, [ type: integer, name: foo, example: 10 ] is valid, whereas [ type: integer, name: foo, example: bar ] is not, as ‘bar’ cannot be cast to an integer.

NEW FUNCTIONALITY

  • viash config inject: A command for inserting a Viash header into your script.

  • YumRequirement: Added a requirement setup for installing through yum. Example: setup: [ [ type: yum, packages: [ wget] ] ]

  • DockerRequirement: Allow using copy and add instructions. Example: setup: [ [ type: docker, add: [ "http://foo.bar ." ]]]

BUG FIXES

  • ViashTest: Fix verbosity passthrough.

  • --help: Fix repeated usage flag when printing the help.
