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 performs a broad modernization of widely used rsyslog
macros to align with modern C practices and support automated
formatting tools like clang-format. The changes focus on improving
syntactic regularity, readability, and tooling compatibility — without
altering behavior.
Macros refactored in this commit now follow a consistent,
statement-like form with explicit trailing semicolons. Where
applicable, macro blocks that define module interfaces (`queryEtryPt`)
have been updated to use simple `if` statements instead of `else if`
chains. While this slightly increases evaluation time, the affected
functions are only called once per module during load time to register
supported interfaces — making the performance cost irrelevant in
practice.
These improvements serve multiple purposes:
- Enable reliable clang-format usage without mangling macro logic
- Simplify reasoning about macro-expanded code for human readers
- Reduce style drift and merge conflicts
- Facilitate development for contributors using assistive tools
- Support future formatting pipelines using:
1. `clang-format`
2. a post-fixup normalization script
Refactored macros:
- MODULE_TYPE_NOKEEP
- MODULE_TYPE_KEEP
- MODULE_TYPE_INPUT
- MODULE_TYPE_OUTPUT
- MODULE_TYPE_FUNCTION
- MODULE_TYPE_PARSER
- MODULE_TYPE_LIB
- DEF_IMOD_STATIC_DATA
- DEF_OMOD_STATIC_DATA
- DEF_PMOD_STATIC_DATA
- DEF_FMOD_STATIC_DATA
- DEFobjStaticHelpers
- SIMP_PROP(...)
And all `queryEtryPt()` dispatch macros:
- CODEqueryEtryPt_STD_MOD_QUERIES
- CODEqueryEtryPt_STD_OMOD_QUERIES
- CODEqueryEtryPt_STD_OMODTX_QUERIES
- CODEqueryEtryPt_STD_OMOD8_QUERIES
- CODEqueryEtryPt_TXIF_OMOD_QUERIES
- CODEqueryEtryPt_IsCompatibleWithFeature_IF_OMOD_QUERIES
- CODEqueryEtryPt_STD_IMOD_QUERIES
- CODEqueryEtryPt_STD_CONF2_QUERIES
- CODEqueryEtryPt_STD_CONF2_setModCnf_QUERIES
- CODEqueryEtryPt_STD_CONF2_OMOD_QUERIES
- CODEqueryEtryPt_STD_CONF2_IMOD_QUERIES
- CODEqueryEtryPt_STD_CONF2_PREPRIVDROP_QUERIES
- CODEqueryEtryPt_STD_CONF2_CNFNAME_QUERIES
- CODEqueryEtryPt_STD_PMOD_QUERIES
- CODEqueryEtryPt_STD_PMOD2_QUERIES
- CODEqueryEtryPt_STD_FMOD_QUERIES
- CODEqueryEtryPt_STD_SMOD_QUERIES
- CODEqueryEtryPt_doHUPWrkr
- CODEqueryEtryPt_doHUP
This general modernization reduces macro misuse, improves DX, and
lays the foundation for a robust, automated style normalization
system.

function modules add functions to rainerscript dynamically,
change http_request into such a module (enabled by default).
This module can be used as a sample for future function modules.
