Port indentation logic to SMIE

[bbatsov]

SMIE is the way to handle indentation in recent Emacs editions http://www.gnu.org/software/emacs/manual/html_node/elisp/SMIE.html AFAIK all major modes should start using it at some point instead of rolling out their custom solutions.

@bbatsov 👍

For reference, the official Puppet grammar… looks like a terrible beast.

[bbatsov]

I've seen worse. I guess only a limited subset of the grammar needs porting (something covering the most common use-cases). One problem with using SMIE, however, is that it's not quite the same in each Emacs release - the version in 24.4 has many improvements AFAIK (because a bunch of prominent packages were rewritten to use it) and that might be problematic on older Emacsen. If the version in 24.1 has too many shortcomings I guess it won't be wise to use SMIE.

@bbatsov I'd start with an optional switch to enable SMIE indentation anyway. I don't know SMIE, and I don't have enough confidence into my grammar skills to make an SMIE variant the default right away ;)

Hey guys, I don't mean to be a pain but when do you think the new indentation system will be ready?

[swsnr]

@tcuthbert We have no ETA. We are busy with many tasks and projects, and SMIE isn't the easiest thing to understand or use.

[tcuthbert]

no problems, are there any workarounds at this point? (I mainly want to keep consistency with my parenthesis alignments) any hackish suggestions welcome. Sorry If this is the wrong forum for such a query, let me know if there's a more suitable one (irc, mailing list etc)

[swsnr]

@tcuthbert There are no workarounds that I'm aware, but I also never really read the old indentation code.

The best “workaround” for this issue is to help use getting SMIE done.
