@johanneskastl I was thinking the same and I'll like to take care of the implementation of this feature.

Considering that:

• Helm charts support .helmignore in order to not include files in the chart
• The current implementation of ct do not take it into account, this mean that in case of files that are not part of the package (e.g.: file in ci folder) every change in those file require a chart bump, also if at the end the chart artefact do not change (same for test folder or any other file/folder that is not shipped in the chart).
• README.md is not an asset that impact the chart functionality, I'm not sure if it should be part of the chart itself or should be omitted from the tarball (but we should keep in the repo) using the .helmignore file.

I have a few option in mind:

• Add the functionality to take .helmignore into consideration during the chart-change evaluation (excluding files that are ignored from .helmignore here. Helm ignore functionality is available here but since is an internal package we can't depend from it and we need to mirror the functionality)
• Add a functionality that omit files from CLI flag/configuration (eg .ctignore file or --ignore-files flag), this seems a bit risky since we can omit files that are part of the final artefact potentially exposing chart developer to issues

Do you have any opinion on that?

EDIT: After looking into repo I found a PR that is aimed to solve the same problem with a solution that is similar to the first proposal.. #411

@mavimo Your first proposal sounds good, nice to see there is already a PR for that.

On a related note, I found that people exclude things in the Github Action definition:

---
name: "Charts: Lint and test"

on:
  pull_request:
    paths:
      - 'charts/**'
      - '!charts/**/README.md'
      - '!charts/**/README.md.gotmpl'

(untested example)

@johanneskastl as I understand it going to stop the pipeline to work if only the readme file is changed, this is not bad but then we need to have a dedicate pipeline only for the version check (plus we need to report all the files & folder to ignore also in the CI pipeline, that might be a bit redundant and counterintuitive for a person working on the chart)

Having this feature would be great! @cpanato, when you'll be free, would you consider (#411)? 🤓
