More examples

When trying to select from more complex files, I'm at a loss on what's possible, and keep failing at creating a proper query.

Take the following yaml:

---
plugins:
  - "@semantic-release/commit-analyzer"
  - "@semantic-release/release-notes-generator"
  - "@semantic-release/gitlab"
  - - "@semantic-release/git"
    - assets:
        - "tbump.toml"
        - "**/pyproject.toml"
        - "**/setup.py"
        - README.md
      message: |-
        chore(release): ${nextRelease.version}

        ${nextRelease.notes}

I would like to retrieve the list under assets. How would I write a query to achieve this?

Some more examples of all the selector features in the documenation would probably help achieve this.

When converted to json, I can get it using dasel -f .releaserc -r json '.plugins.[3].[1].assets', but that would require a consistent ordering, which isn't guaranteed.

The issue here is that dasel expects each item within the plugins list to be of the same type, when in reality the first 3 are strings, and the 4th is is a list.

I can update the dynamic selector to be able to handle type checks.

Let me work on a quick POC for this to validate the use-case and solution.

[TomWright]

The customisation I'm working on will give you the ability to do the following:

dasel  -f .releaserc -r yaml -w json -m '.plugins.([@]=array).([@]=map).(-=assets)'
- tbump.toml
- '**/pyproject.toml'
- '**/setup.py'
- README.md

In English this means,

1. Find any items within the plugins array that are of type array.
2. Find me any items within that array that are of type map.
3. Find me any properties within that map that have a key of assets.

As an aside, if you just want to find any item anywhere within your file that has a key of assets, you could do the following already using the saerch selector.

$ dasel -f .releaserc -r yaml -m '.plugins.(?:-=assets)'                             
- tbump.toml
- '**/pyproject.toml'
- '**/setup.py'
- README.md

Another example:

dasel -f .releaserc -r yaml '.plugins.([@]=array)([0]=@semantic-release/git).[1].assets'

It searches for a plugin item that is an array where the first item in the array is equal to @semantic-release/git

I'm going to do a bit more testing on my branch and then I'll merge. This will likely go out in the next release.

[rhtenhove]

Gave this a try locally, and works wonders, thanks for the improvements!

[TomWright]

This is merged to master now but is not in a tagged release yet. It will be going out in the next release though 👍

[TomWright]

This is released as of v1.22.0.

[rhtenhove]

I've tried to upgrade this one to v2, and came up with the following monstrosity:

dasel -f .releaserc -r json ".plugins.all().filter(equal(type(),array)).[1].as
sets"

It makes some assumptions on the structure, such as the order in the nested array, but my main question is, can it be written more concise?

---
plugins:
  - "@semantic-release/commit-analyzer"
  - "@semantic-release/release-notes-generator"
  - "@semantic-release/gitlab"
  - - "@semantic-release/git"
    - assets:
        - "tbump.toml"
        - "**/pyproject.toml"
        - "**/setup.py"
        - README.md
      message: |-
        chore(release): ${nextRelease.version}

        ${nextRelease.notes}

I can't say this is much nicer, but it will at-least work if the ordering is changed around:

$ echo '---
plugins:
  - "@semantic-release/commit-analyzer"
  - "@semantic-release/release-notes-generator"
  - "@semantic-release/gitlab"
  - - "@semantic-release/git"
    - assets:
        - "tbump.toml"
        - "**/pyproject.toml"
        - "**/setup.py"
        - README.md
      message: |-
        chore(release): ${nextRelease.version}

        ${nextRelease.notes}' | dasel -r yaml 'plugins.all().filter(equal(type(),array)).all().filter(equal(type(),object)).assets?'
- tbump.toml
- '**/pyproject.toml'
- '**/setup.py'
- README.md
- ```

Excellent, thank you! It's working wonders.

I've also seen your comment in #352, and I'm using this for an append() to that list which is working nicely.

Thanks again!
