Ok. Thanks.I'll do more research on indentation conventions. From: Jonas Bernoulli To: David Gonzalez Cc: "emacs-devel@gnu.org" Sent: Sunday, February 21, 2016 7:58 PM Subject: Re: [ELPA] New package: arbitools The library provides the wrong feature (`arbitools-mode').  It should instead provide the feature which matches the filename (but of course without the ".el" suffix): `arbitools'. Also there is a space missing in ";;;Commentary:". And you might want to consider not putting closing parens in the wrong place.  You should fix that at least for the definition of `arbitools-mode'. For data, like the value of `arbitools-highlights', which is likely to be extended in the future it is okay to put closing parens on a separte line.  But you should put both closing parents on the same line and indent that line correctly.  Actually you should reindent the complete value.  But first you need to correctly comment the commented lines, replacing ";(" with ";; (" (also in other definitions).  Then mark the `defvar' and use `M-x indent-region RET'.
