From 8dc099b955197c7100937d5fafc60c4b9681a5ab Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Fri, 2 Jun 2023 18:04:00 -0700 Subject: til: add til_get_module_names() helper Composite modules that want to provide "all" aliases for modules like rtv have to construct a comma-separated string of all module names, usually filtered by some flags. This helper does just that, but it does add yet another open_memstream() user to revisit when those all get fixed up. --- src/til.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) (limited to 'src/til.c') diff --git a/src/til.c b/src/til.c index c680db8..ee42e68 100644 --- a/src/til.c +++ b/src/til.c @@ -4,6 +4,7 @@ #include #include #include +#include #include #include #include @@ -166,6 +167,35 @@ void til_get_modules(const til_module_t ***res_modules, size_t *res_n_modules) } +char * til_get_module_names(unsigned flags_excluded) +{ + const til_module_t **modules; + size_t n_modules; + char *buf; + size_t bufsz; + FILE *fp; + + /* FIXME TODO: more unportable memstream! */ + fp = open_memstream(&buf, &bufsz); + if (!fp) + return NULL; + + til_get_modules(&modules, &n_modules); + for (size_t i = 0, j = 0; i < n_modules; i++) { + const til_module_t *mod = modules[i]; + + if ((mod->flags & flags_excluded)) + continue; + + fprintf(fp, "%s%s", j ?
