bool2str v1.0.0

bool2str

(cond ? yes : no) but throw if arg types are not (bool, string, string).

Why?

• To help with situations like YAML bool/string accidents: When you evaluate an unquoted YAML no as a naive if () condition in JavaScript or PHP, it becomes equivalent to yes, since both are non-empty strings.

API

This module exports one function that holds some others:

bool2str(cond, yes, no, trace)

If cond is a boolean, and yes and no both are strings, return (cond ? yes : no). If any of the arguments have the wrong type, instead throw an error complaining about them. The trace (ideally a string with a hint) will be appended to the error message in order to help you find where the problem originated.

bool2str.curry(yes, no, trace) (alias: .c)

Verify that the yes and no arguments are strings. Throw an error otherwise. If they are, prepare (and return) a function that takes one argument cond in order to then call bool2str with the other, pre-defined arguments.
