Module: Replacer

[whereareiam]

Motivation

Some users expressed the need for a centralized and flexible way to replace placeholders across multiple configuration files. Until now, this often required duplicating sensitive or shared values (e.g. database credentials, service endpoints, secrets) across many different configs, making maintenance error-prone and inconvenient.

To solve this, I created the Replacer module, which allows defining placeholder replacement rules in a single configuration and applying them dynamically across multiple files. This eliminates the need to manually update the same values in many places and reduces the risk of configuration inconsistencies.

#1354

Modification

• Added a new Replacer module that:
  • Processes configurable replacement rules
  • Supports multiple targets (task, service, environment, group)
  • Allows defining file patterns for mass replacement
  • Supports multiple placeholders per rule
  • Allows different search and replace strategies (ALL, FIRST, etc.)
  • Supports dynamic values with nested placeholders (e.g. %taskName%, %nodeId%, %serviceHost%)
• Added example configuration demonstrating:
  • Lobby MOTD replacement
  • Endpoint generation
  • Forwarding secrets for Paper & Velocity
  • Multi-target shared secrets

Result

• Before:
  Placeholder values and secrets had to be duplicated manually across many different configuration files, making updates tedious and risky.

• After:
  All placeholder replacements can now be managed from a single centralized configuration, automatically applied to all matching files and targets.

• Impact:

  • Much easier configuration management
  • No need to store sensitive data in multiple configs
  • Reduced risk of mismatched or outdated values

Hi, thank you for your contribution. I think it makes more sense if you first add this module as a third-party module in CloudNet, as we already do with the CloudNet-REST module, since we currently do not have the capacity to maintain and further develop the module if necessary.

Therefore, I would be very grateful if you could publish the module yourself and add it here https://github.com/CloudNetService/CloudNet/blob/nightly/modules.json with a PR. If you need any help with this, please let me know.

This PR was closed and the module was moved to a dedicated repository.
A follow-up PR was opened to add it as a third-party module.
