Functions

strict ([t[, ...]])

Makes a given table strict. It mutates the passed-in table (or creates a new table) and returns it. The returned table is strict, indexing or assigning undefined fields will raise an error.

Parameters:

• t a table
• ... a vararg list of allowed fields in the table.

Returns:

the passed-in table t or a new table, patched to be strict.

Usage:

 local t = strictness.strict()
 local t2 = strictness.strict({})
 local t3 = strictness.strict({}, 'field1', 'field2')

is_strict (t)

Checks if a given table is strict.

Parameters:

• t a table

Returns:

true if the table is strict, false otherwise.

Usage:

local is_strict = strictness.is_strict(a_table)

unstrict (t)

Makes a given table non-strict. It mutates the passed-in table and returns it. The returned table is non-strict.

Parameters:

• t a table

Usage:

local unstrict_table = strictness.unstrict(trict_table)

strictf (f)

Creates a strict function. Wraps the given function and returns the wrapper. The new function will always run in strict mode in its environment, whether or not this environment is strict.

Parameters:

• f a function, or a callable value.

Usage:

 local strict_f = strictness.strictf(a_function)
 local result = strict_f(...)

unstrictf (f)

Creates a non-strict function. Wraps the given function and returns the wrapper. The new function will always run in non-strict mode in its environment, whether or not this environment is strict.

Parameters:

• f a function, or a callable value.

Usage:

 local unstrict_f = strictness.unstrictf(a_function)
 local result = unstrict_f(...)

run_strict (f[, ...])

Returns the result of a function call in strict mode.

Parameters:

• f a function, or a callable value.
• ... a vararg list of arguments to function f.

Usage:

local result = strictness.run_strict(a_function, arg1, arg2)

run_unstrict (f[, ...])

Returns the result of a function call in non-strict mode.

Parameters:

• f a function, or a callable value.
• ... a vararg list of arguments to function f.

Usage:

local result = strictness.run_unstrict(a_function, arg1, arg2)
