Add a flag to search to not install demo/trial app

[sudomakesandwich]

It would be awesome to add a flag to search, and maybe to other commands to, so that it doesn't show paid apps. By paid apps I mean apps that need to be purchased after several days or otherwise they don't work anymore (trail versions).
As I'm aware of that not being automatically each cask should have a field containing free to be found.

This is a Good Idea as far as I'm concerned.

I've previously advocated for adding an optional license stanza to the DSL (#1860 (comment)). My proposal would be that license stanzas would not be free-form, but only accept one of several defined constants (or nil/unknown).

An alternative, more general, implementation would be a tags stanza, accepting key/value pairs, in which :license was one of the accepted keys.

I am more than happy to implement either of those forms if enough people request it. @kevinSuttle gave a +1 in the discussion referenced above, so that's three of us so far.

I’m for closing this. There hasn’t been much support for this option in this issue or on the project as a whole (I don’t recall seeing a duplicate for this).

Circling back (once again) to the “we’re not a discoverability service” argument, users should have reasonable knowledge of the software before trying to install it. Will leave the final decision to @rolandwalker, but I see minimal value in this.

As to the exact title of the issue (affecting install), no problem with closing.

What we are in the process of doing is making that info available in search or list. The process is going well; nearly half of Casks have license info. It's time to start displaying it soon.

No issues there; I agree.

Closing, then.
