35 .Nd FreeBSD core module
38 contains core functionality that does not have a more fitting module.
40 Before hooking into or using the functionality provided by
42 it must be included with a statement such as the following:
44 .Dl local core = require("core")
46 The following raw key code constants are defined in
48 .Bl -tag -width KEY_BACKSPACE -compact -offset indent
51 Should generally be checked along with
53 for backspace functionality.
55 The enter key, or hard return.
58 Should generally be checked along with
60 for backspace functionality.
63 The following key-string constants are defined in
65 .Bl -tag -width KEYSTR_ESCAPE -compact -offset indent
69 The ANSI CSI sequence.
72 The following menu entry type constants are defined in
74 .Bl -tag -width MENU_CAROUSEL_ENTRY -compact -offset indent
76 Return to the parent menu.
80 A menu entry that serves as a separator.
82 A menu entry that opens a submenu when selected.
83 .It Ic MENU_CAROUSEL_ENTRY
84 A menu entry that rotates through items like a carousel upon selection of the

93 .Ss Exported functions
94 The following functions are exported from
96 .Bl -tag -width core.getACPIPresent -offset indent
97 .It Fn core.setVerbose verbose
102 is omitted, toggle the current verbose setting.
103 .It Fn core.setSingleUser singleUser
108 is omitted, toggle the current single user setting.
109 .It Fn core.getACPIPresent checkingSystemDefaults
110 Check whether ACPI is present.
111 This will only be accurate for i386-compatible loaders, including non-UEFI
112 loaders on amd64 systems.
114 .Fa checkingSystemDefaults
115 is true, ignore the current value of
116 .Ev hint.acpi.0.disabled .
117 Otherwise, return true only if ACPI is both present and not disabled.
118 .It Fn core.setACPI acpi
121 .Ev hint.acpi.0.disabled ,
123 .Ev loader.acpi_disabled_by_user .
126 is omitted, toggle the current ACPI setting.
127 .It Fn core.setSafeMode safeMode
128 Set the safe mode setting.
130 .Ev kern.smp.disabled ,
132 .Ev hw.ata.atapi_dma ,
135 .Ev kern.eventtimer.periodic ,
137 .Ev kern.geom.part.check_integrity .
140 is omitted, toggle the current safe mode setting.
141 .It Fn core.kernelList
142 Returns a table of kernels to display on the boot menu.
150 .Ic kernels_autodetect
153 kernels will be autodetected from the current system.
154 .It Fn core.bootenvDefault
155 Returns the default boot environment, nil if unset.
156 .It Fn core.bootenvList
157 Returns a table of boot environments, or an empty table.
158 These will be picked up using the
164 .It Fn core.setDefaults
165 Resets ACPI, safe mode, single user, and verbose settings to their system
167 .It Fn core.autoboot argstr
168 Loads the kernel and specified modules, then invokes the
174 .It Fn core.boot argstr
175 Loads the kernel and specified modules, then invokes the
181 .It Fn core.isSingleUserBoot
185 .It Fn core.isZFSBoot
191 .It Fn core.isSerialBoot
192 Returns true if we are booting over serial.
198 .It Fn core.isSystem386
199 Returns true if this bootloader was compiled as an i386 binary.
200 This generally applies to i386 loaders as well as non-UEFI loaders on amd64.
201 .It Fn core.deepCopyTable tbl
202 Recursively deep copies
204 and returns the result.
205 .It Fn core.popFrontTable tbl
206 Pops the front element off of
208 and returns two return values: the front element, and the rest of the table.
209 If there are no elements, this returns nil and nil.
210 If there is one element, this returns the front element and an empty table.
211 This will not operate on truly associative tables; numeric indices are
