die_if_no_valid_ffmpeg_installed!()

Die with an informative error message if ffmpeg is not installed. This is only used for certain functions (such as animation), so only run this when you know the user wants to perform one of them.
# File lib/lolcommits/cli/fatals.rb, line 52 def self.die_if_no_valid_ffmpeg_installed! return if Platform.valid_ffmpeg_installed? fatal 'FATAL: ffmpeg does not appear to be properly installed!' exit 1 end
die_if_not_vcs_repo!()

If we are not in a git repo, we can't do git related things! Die with an informative error message in that case.
# File lib/lolcommits/cli/fatals.rb, line 61 def self.die_if_not_vcs_repo! debug 'Checking for valid VCS repo' current = File.expand_path('.') parent = File.dirname(current) while current != parent return if VCSInfo.repo_root?(current) current = parent parent = File.dirname(current) end fatal "You don't appear to be in a directory of a supported vcs project." exit 1 end
die_on_fatal_platform_conditions!()

Check for platform related conditions that could prevent lolcommits from working properly.
Die with an informative error message if any occur.
