34 .Nd FreeBSD config module
37 contains configuration and module loading functionality.
39 Before hooking into or using the functionality provided by
41 it must be included with a statement such as the following:
43 .Dl local config = require("config")
44 .Ss Exported functions
45 The following functions are exported from
47 .Bl -tag -width "config.setCarouselIndex(id, idx)" -offset indent
48 .It Fn config.getCarouselIndex id
49 Returns the currently chosen index in the carousel menu entry described by
53 for a more in-depth explanation of carousels.
54 .It Fn config.setCarouselIndex id idx
55 Set the chosen index for the carousel menu entry described by
59 A lookup will be done as needed to determine what value
61 actually corresponds to.
62 .It Fn config.readConfFiles files loaded_files
66 .Ev loader_conf_files .
67 The caller may should pass in a table as the
69 argument, which uses filenames as keys and any non-nil value to indicate that
70 the file named by the key has been loaded.
71 .It Fn config.processFile name silent
74 as a configuration file.
77 exists and parses without error, false otherwise.
81 .Fn config.processFile
82 will not consider a failure to read the file as a failure.
83 .It Fn config.parse text
86 as a configuration file.
87 This is used internally by
88 .Fn config.processFile
89 to parse the contents of a configuration file.
90 Returns true if parsing succeeds without error, false if an error occurred.
91 A message is also printed to the console if an error is encountered.
92 .It Fn config.loadKernel other_kernel
102 Otherwise, it will try to load
105 .Pa /boot/{other_kernel} ,
109 The latter is tried in case an absolute path has been specified to the kernel
112 is amended to include the directory the kernel was found in if either of these
113 paths result in a loaded kernel.
115 If no kernel was loaded from either of these paths,
116 .Fn config.loadKernel
117 will attempt to load a kernel named
121 instead of attempting to load a kernel named
124 Returns true if a kernel was loaded, false if no kernel was loaded.
125 .It Fn config.selectKernel kernel
128 to the kernel that will be loaded when either
133 This is usually called by the menu system as the kernel selector carousel is
135 .It Fn config.load file reload
138 as a configuration file.
142 .Pa /boot/defaults/loader.conf
145 will then silently attempt to process any files specified in
146 .Ev loader_conf_files
151 configuration will also be checked as part of
153 Before returning, all
158 .It Fn config.reload file
161 as a configuration file.
163 will restore the environment to how it existed before the last config was
164 loaded, then it will invoke
165 .Fn config.load file .
166 Before returning, all
169 .It Fn config.loadelf
170 Loads all ELF objects, the selected kernel as well as any modules configured to
