Install specific package version with a help of Brewfile

[niparx]

I would like to have a feature to install specific version of a package. And to define it in Brewfile. Something like this:

#CMake 3.14.4
brew "https://raw.githubusercontent.com/Homebrew/homebrew-core/3d7d9f99f1b273c469120eebf765119369f1ae00/Formula/cmake.rb"

Currently it won't work. brew makes url lowercase, which, at the end won't be valid formula and Formula in url makes the difference:

$ brew bundle -v
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
curl: (22) The requested URL returned error: 404 Not Found
Error: Failure while executing; `/usr/bin/curl -q --show-error --user-agent Homebrew/2.1.11\ \(Macintosh\;\ Intel\ Mac\ OS\ X\ 10.14.6\)\ curl/7.54.0 --fail --location --remote-time --continue-at 0 --output /Users/user/Library/Caches/Homebrew/Formula/cmake.rb https://raw.githubusercontent.com/homebrew/homebrew-core/3d7d9f99f1b273c469120eebf765119369f1ae00/formula/cmake.rb` exited with 22. Here's the output:
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

May be, if that would be fixed, we would be able to install specific versions of packages in Brewfile

From the README (https://github.com/Homebrew/homebrew-bundle#note):

Homebrew does not support installing specific versions of a library, only the most recent one, so there is no good mechanism for storing installed versions in a .lock file.

If your software needs specific versions then perhaps you'll want to look at using Vagrant to better match your development and production environments.

If you really, really want to use specific versions forever: use brew extract and put them in your own tap. We will never support installing from specific URLs like that.

How about adding extract command to Brewfile? @MikeMcQuaid

[MikeMcQuaid]

@figroc I can't see how that would work? We don't want to make it extremely easy to sit on old outdated versions because it's generally A Bad Idea.

In fact, extract works just like tap. I come across the versioning issue because of the formula protobuf. The version 3.11.0 of protobuf breaks my cmake project. I have no choice but stick with the version 3.10.x of protobuf (the 3rd party dependency).
