Hi, some time ago I started using a new code editor[1], and I found that unlike my other editor[2] it has difficulties in divinating the indentation styles of various code bases. Fortunately, a reasonable standard has emerged that lets a code base declare how to indent, in a way that editors can easily understand: https://editorconfig.org/ Here's a declaration I've been using for our Ruby code: # top-most EditorConfig file root = true # 2 space indentation [*.rb] indent_style = space indent_size = 2 And here's the one from libstorage-ng, capturing the not-quite-trivial rules of "the Tab key indents 4 columns, but compress 8 spaces into Tab characters" # https://EditorConfig.org -*- ini -*- # This is a unified way to tell all your editors # about the proper indentation style in this repo. # # Emacs: https://github.com/editorconfig/editorconfig-emacs#readme # Vim: https://github.com/editorconfig/editorconfig-vim#readme # VS Code: https://marketplace.visualstudio.com/items?itemName=EditorConfig.EditorConfi... # don't continue looking in upper directories, this is the top level root = true [*.{h,cc}] indent_style = tab indent_size = 4 tab_width = 8 I've added it to a couple of repos so far, where I needed it. 1. Should we improve these declarations? (Add trim_trailing_whitespace[3], insert_final_newline) 2. Should we add a master copy to yast-devtools? (It would need to be copied manually, but it would serve as the representation of the current best practice) [1]: https://en.wikipedia.org/wiki/Visual_Studio_Code [2]: https://en.wikipedia.org/wiki/GNU_Emacs [3]: https://github.com/yast/yast-packager/pull/441#discussion_r294163050 thanks to Lada for prompting this -- Martin Vidner, YaST Team http://en.opensuse.org/User:Mvidner
