dumper

Variable dumping/inspection helpers.

Sharedexport(var, level, seen, strict) → stringSource ☍

Provides a human & machine readable version of variables. Equivilent to PHP's var_export: the output compiles back to an equivalent value, except that functions, panels and cyclic references become commented placeholders unless strict is set.

Parameters

• varanyInput variable.
• levelnumber?Initial indent level, for tables. Defaults to 0.
• seentable<table, boolean?>?Tables currently being exported above this one, used to detect cyclic references. Defaults to an empty table.
• strictboolean?Raise an error on a value with no Lua form or a cyclic reference, instead of writing a placeholder.

Returns

1. stringReadable version.

Sharedkeyify(var, level, seen, strict) → stringSource ☍
