Pls, 'scuz in advance if this is in the wrong pocket.
Original post was a technical query: https://forum.sublimetext.com/t/introducing-a-new-comment-marker/2086/1
Thanks to @sublimator and @adzenith, I stumbled on an asciidoc tm.bundle.
I in turn forked the above and shuffled things around to better fit with the ST2 directory/naming conventions, See the README for installation instructions.
Code is at: github.com/tsyroid/asciidoc-sublime.git
All snippets have been tested and are working (baring a few superficial quirks) on ST2 latest build (2095). I'll be exploring and testing more in the coming days. As noted in previous post, I'm editing a book, working in AsciiDoc, and using ST2 all-the-live-long-day. So I'll know soon enough if the plugin is useful in a "daily working" context.
I see there's a "Sublime Plugin GitHub" venture happening... I don't think my meager efforts are worthy of entrance to the "Big Sublime House" yet, but I would appreciate anyone interested clone the repo and help me draw a picture of how to better organize, what needs fixing, etc. I'm relatively proficient with git, but a relative newbie with ST2 internals, unknown around these forums, and not a programmer (I document what you guys write ). So be gentle please.
