From 1589064f3301e7a7066a08063469da7e4014c128 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Thu, 16 Jul 2026 18:55:13 +0200 Subject: [PATCH] api-parse-options.adoc: document hidden and OPT_*_F option macros In "Documentation/technical/api-parse-options.adoc", the list of option macros does not mention the `OPT_*_F()` macro variants that take a trailing `flags` argument, nor the `OPT_HIDDEN_GROUP()` and `OPT_HIDDEN_BOOL()` convenience macros. Now that a previous commit documents the per-option flags, let's document these macros too: - Add a paragraph explaining the `OPT_*_F` convention and how it relates to the per-option flags. - Document `OPT_HIDDEN_GROUP()`, introduced in a previous commit, right after `OPT_GROUP()`. - Document `OPT_HIDDEN_BOOL()` right after `OPT_BOOL()`.
