How do I assign a literal value?

[ejunker]

I want to hard code a literal value. Here is a minimal example:

$fm->define('Resume')->setDefinitions([
    'salary' => 'd',
]);

The problem is I also have a global function d() and it calls the d() function instead of just using the literal value 'd'. Is there a way to assign literal string values?

Hmm, that is a bit of a problem. The issue is the string d is callable on your machine.

One way to force the string would be to do:

$fm->define('Resume')->setDefinitions([
    'salary' => function () { return 'd'; },
]);

That would work but it is a bit verbose. As a user I would expect a literal string to assign a literal string. It would be a breaking change but maybe in the future it could be changed so that if you want to call a callable that you would have to do something like like this.

$fm->define('Foo')->setDefinitions([
    'bar' => $fm->call('myCallable'),
]);

I wonder if I could refactor the generator stuff so that people could choose to disable callables. Would that work for you. In other words, only support closures rather than callables, as an option.

[ejunker]

That would work. If callables were disabled I still like the idea of having a helper method that you could pass a string and it would return a closure that calls the callable. Like the $fm->call() in my previous example.

I'll have a think how I can make this work so it's really nice to use.
