exists

Tests whether a unit template exists.

Function

Synopsis

btech.template.exists( reference )

Arguments

string reference: The unit-template reference.

Returns

boolean exists: Whether the template exists.

Notes

An empty reference or one containing .., /, or \ raises mux.arg.invalid. A well-formed missing reference returns false. When the referenced file exists but is not a valid template, the function raises btech.template.invalid.
