This commit applies the new canonical formatting style using `clang-format` with custom settings (notably 4-space indentation), as part of our shift toward automated formatting normalization.
⚠️ No functional changes are included — only whitespace and layout modifications as produced by `clang-format`.
This change is part of the formatting modernization strategy discussed in:
https://github.com/rsyslog/rsyslog/issues/5747
Key context:
- Formatting is now treated as a disposable view, normalized via tooling.
- The `.clang-format` file defines the canonical style.
- A fixup script (`devtools/format-code.sh`) handles remaining edge cases.
- Formatting commits are added to `.git-blame-ignore-revs` to reduce noise.
- Developers remain free to format code however they prefer locally.
This commit adds the initial implementation of the `mmaitag` module,
a pluggable AI-based message classification processor.
The module supports two providers:
- `gemini`: uses the Gemini API via libcurl and JSON-C
- `gemini_mock`: a deterministic in-memory mock used for testing
Each log message is classified individually and tagged with a label
stored in a configurable message variable (default: `$.aitag`).
Included:
- Provider abstraction layer (`ai_provider.h`)
- Gemini provider with API key support (inline or via file)
- Prompt customization and input property selection
- Two regression tests: basic and invalid-key scenarios
- Sphinx documentation under `doc/configuration/modules`
Note: mmaitag is in its infancy and primarily a PoC. Future work
will improve batching, performance, and add more providers.
