Hi, as you know, our Ruby style guide prescribes that no tabs be used for indentation. (A very practical rationale is that GitHub reviews display tabs at 4 columns instead of the Only Correct Value 8, and code then looks misaligned.) https://github.com/SUSE/style-guides/blob/master/Ruby.md#code-layout To help you with keeping this rule you can use the attached file. Git commands showing diffs will then highlight initial tabs. (I am also looking into editor settings, checking other style guide aspects, and maybe automatic checks for pull requests, but I don't have anything for general use yet.) -- Martin Vidner, Cloud & Systems Management Team http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu
