 Replace isValid() calls with assert() 
There's more value on showing how `assert()` displays the validation
messages than simply showing if `isValid()` returns `true` or `false`.

However, that increases the chances of having outdated documentation, so
I created a doc linter that updates the Markdown files with the
correct message.

TrueVal

  • TrueVal()

Validates if a value is considered as true.

v::trueVal()->assert(true);
// Validation passes successfully

v::trueVal()->assert(1);
// Validation passes successfully

v::trueVal()->assert('1');
// Validation passes successfully

v::trueVal()->assert('true');
// Validation passes successfully

v::trueVal()->assert('on');
// Validation passes successfully

v::trueVal()->assert('yes');
// Validation passes successfully

v::trueVal()->assert('0.5');
// → "0.5" must evaluate to `true`

v::trueVal()->assert('2');
// → "2" must evaluate to `true`
