decode_modifiers(3) Arcan Lua API decode_modifiers(3) NAME decode_modifiers - Convert a modifier-bitmap to a textual representation. SYNOPSIS modtbl or modstr decode_modifiers( modval, separator ) DESCRIPTION The input table that is provided as part of the _input event handler has a modifiers field that is a bitmap of different modifier states. This bitmap can be converted to either an integer indexed table of text representations of each present modifier, or as a single concatenated string with the char- acter in separator added between the individual modifiers. If the separa- tor argument is provided, and is a non-empty string, then modstr will be returned. Otherwise modtbl will be returned. The different possible text representations of the modifiers are: "lshift", "rshift", "lalt", "ralt", "lctrl", "rctrl", "lmeta", "rmeta", "num", "caps", "mode" NOTES 1 If the separator is an empty string, the '_' character will be used as separator instead. 2 There is also a modifier bit to indicate if the event was a repeat (if the input platform supports that). This will not be added to the decoded output as it would subtly break a lot of 'naive' approaches to keybindings. EXAMPLE function decode_modifiers0() print( table.concat(decode_modifiers( 0xffffff ), "0) ); print( decode_modifiers(0xffffff, "_") ); end system August 2026 decode_modifiers(3)
