Utility function to compare Rails migration files on a remote server against those locally. This is helpful for ascertaining which migrations will need to be run during a deploy.
- You use
zsh - You have a properly configured
$fpath(more on this below) - Your local source directory has the same name as the app directory on the remote server
Clone the respository somewhere.
$ git clone git://github.com/tmking/compare_migrations.git ~/.zsh/plugins/compare_migrations
Alternatively, you can create a submodule.
$ git submodule add git://github.com/tking/compare_migrations.git ~/.zsh/plugins/compare_migrations
Add the functions subdirectory to your $fpath. This should be done in your .zshrc.
$ fpath+=$HOME/.zsh/plugins/*/functions/*(N)
For tab completion to work, you'll need to add the Completion directory as well:
$ fpath+=$HOME/.zsh/plugins/*/Completion/*(N)
This plugin provides two commands, compare_migrations and diff-remote.
compare_migrations <remote server>
diff-remote <remote server> <remote path> <local path>
compare_migrations will only work when you're inside of the source directory.
