HOWTO use replacements with more advanced regex?

[sdurrheimer]

Hi @miniscruff,

I'm trying the replacements feature to change the version within my Helm Chart.yaml file.

The file presents itself as the following:

version: 0.1.0

dependencies:
  - name: mysql
    repository: https://charts.bitnami.com/bitnami
    tags:
      - bitnami-mysql
    version: ~8.8.8
    condition: mysql.enabled

If I use the following configuration, the main version and dependency version are changed:

replacements:
- path: Chart.yaml
  find: 'version: .*'
  replace: 'version: {{.VersionNoPrefix}}'

But If I do the following to make sure the line strictly start with the version string without spaces in front of it, the replacement doesn't happen at all:

replacements:
- path: Chart.yaml
  find: '^version: .*'
  replace: 'version: {{.VersionNoPrefix}}'

How can I make this work properly?

The second version works for me after copy pasting your Chart.yaml and replacements config. I don't see anything wrong and was not able to run into any issues myself.

Hum true, I tried to simplify the example for the sake of this question of not making it too verbose, but indeed does work with it (I should have verified it, sorry for that).

That being said it doesn't with the following complete file:

Chart.yaml

apiVersion: v2
name: cycloid
description: A Helm chart for Cycloid, the Hybrid Cloud DevOps Collaboration Platform
type: application

# This is the chart version. This version number should be incremented each time you make changes
# to the chart and its templates, including the app version.
# Versions are expected to follow Semantic Versioning (https://semver.org/)
version: 0.2.0

# This is the version number of the application being deployed. This version number should be
# incremented each time you make changes to the application. Versions are not expected to
# follow Semantic Versioning. They should reflect the version the application is using.
# It is recommended to use it with quotes.
appVersion: "2.3.1"

kubeVersion: ">= 1.18.0 <= 1.22.0"

Ok it seems the multiline flag is not enabled for the replacements regex so it is not finding the version ( weird it works for the first one and my other examples though ). You can fix this by prefixing your Find value with (?m) but I will release a "bug fix" later to enable multiline by default as it wouldn't make sense otherwise.

[miniscruff]

This should now be resolved by the latest release. Regex flags are now customizable with "multiline" being on by default. If anything similar happens again please file an issue.
