=== Restricted tables ===
Only ''restricted'' tables are accessible within the restricted environment -- essentially, the real table instances are kept local to prevent unrestricted access to variables within the restricted environment. Most table functions within the restricted environment have been replaced by restricted table-aware versions, with the exception of the {{api|gsub}} function (use the restricted table-aware {{api|rtgsub}} instead of table lookup functionality is desired).

The following table-related functions are usable inside the restricted environment:
{| class="darktable"
| colspan="7" align="left" style="padding: 0.3em; background: #282828" | '''Restricted Table Library'''
|-
| width="14%" | rtable.next
| width="14%" | rtable.pairs
| width="14%" | rtable.ipairs
| width="14%" | rtable.unpack
| width="14%" | rtable.newtable
| width="14%" | rtable.maxn
| width="16%" | rtable.insert
|-
| rtable.remove || rtable.sort || rtable.concat || rtable.wipe || rtable.type || rtable.rtgsub ||  
|-
| colspan="7" align="left" style="padding: 0.3em; background: #282828" | '''Table Library''' (restricted-table aware)
|-
| table.maxn || table.insert || table.remove || table.sort || table.concat || table.wipe || table.new
|-
| colspan="7" align="left" style="padding: 0.3em; background: #282828" | '''Global API'''
|-
| newtable || pairs || ipairs || next || unpack || wipe || tinsert
|-
| tremove || type || rtgsub
| colspan="4" |  
|}

Note that as the restricted environment doesn't contain proper function references, table.sort's second argument (comparison function) may not be used from within the restricted environment.

=== Other functions ===
The math and string standard library tables are provided in their entirety. The following table lists additional global functions that are also available in the restricted environment
{| class="darktable"
|-
| width="9%" | select
| width="9%" | tonumber
| width="9%" | tostring
| width="9%" | print
| width="9%" | format
| width="9%" | gmatch
| width="9%" | gsub
| width="9%" | strbyte
| width="9%" | strchar
| width="9%" | strconcat
| width="9%" | strfind
|-
| strjoin || strlen || strlower || strmatch || strrep || strrev || strsplit || strsub || strtrim || strupper || abs
|-
| acos || asin || atan || atan2 || ceil || cos || deg || exp || floor || frexp || ldexp
|-
| log || log10 || max || min || mod || rad || random || sin || tan ||  
|}

== Frame handle methods ==
Real frame userdata values may not exists within the restricted environment; instead, it the restricted environment may contain frame references (introduced via the :SetFrameRef("name", frame) method). A limited subset of the widget API can be invoked upon those references; only methods marked with a star may be called on references to non-protected frames.

== Control methods ==
Additional methods are available as part of the control table; allowing functionality somewhat resembling proper functions within the protected environment.
; control:CallMethod("methodName", ...) : insecurely calls methodName method of the restricted environment's owner.
; control:Run("body", ...) : executes Lua code in body with the provided arguments; self is the handle of the environment's owner.
; control:RunFor(handle, "body", ...) : executes Lua code in body with the provided arguments; self is the argument value.
; control:RunAttribute("snippetAttr", ...) : executes the method contained in the snippetAttr attribute of the restricted environment owner with self, ... as arguments.
; control:ChildUpdate("snippetid", message) : executes the contents of "_childupdate-''snippetid''" (or, if that attribute is nil/false, "_childupdate"), on all protected children (and children of children) of the restricted environment owner with (self, scriptid, message) arguments.
