From 7ff8ef94c05ae6386463b63f3ba25add52340d8b Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Sat, 12 Mar 2022 17:29:26 -0800 Subject: til_settings: always describe relevant settings The existing iterative *_setup() interface only described settings not found, quietly accepting usable settings already present in the til_settings_t. This worked fine for the existing interactive text setup thing, but it's especially problematic for providing a GUI setup frontend. This commit makes it so the *_setup() methods always describe undescribed settings they recognize, leaving the setup frontend loop calling into the *_setup() methods to both apply the description validation if wanted and actually tie the description to respective setting returned by the _setup() methods as being related to the returned description. A new helper called til_settings_get_and_describe_value() has been introduced primarily for use of module setup methods to simplify this nonsense, replacing the til_settings_get_value() calls and surrounding logic, but retaining the til_setting_desc_t definitions largely verbatim. This also results in discarding of some ad-hoc til_setting_desc_check() calls, now that there's a centralized place where settings become "described" (setup_interactively in the case of rototiller). Now a GUI frontend (like glimmer) would just provide its own setup_interactively() equivalent for constructing its widgets for a given *_setup() method's chain of returned descs. Whereas in the past this wasn't really feasible unless there was never going to be pre-supplied settings. I suspect the til_setting_desc_check() integration into setup_interactively() needs more work, but I think this is good enough for now and I'm out of spare time for the moment. --- src/setup.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/setup.h') diff --git a/src/setup.h b/src/setup.h index 878e68b..5135b8e 100644 --- a/src/setup.h +++ b/src/setup.h @@ -3,6 +3,6 @@ #include "til_settings.h" -int setup_interactively(til_settings_t *settings, int (*setup_func)(til_settings_t *settings, til_setting_desc_t **next), int defaults); +int setup_interactively(til_settings_t *settings, int (*setup_func)(til_settings_t *settings, const til_setting_t **res_setting, const til_setting_desc_t **res_desc), int defaults); #endif -- cgit v1.2.1
