[WIP] Add Muse reader

[link2xt]

I have created a basic Muse reader. It supports headings, inline markup and footnotes, but no tables and lists. It is far from full markup support, but it satisfies my needs so I plan to continue development slowly from now on. Hope it gets merged.

[jgm]

I'd rather not merge until this has support for tables and lists.

@jgm Ok, will make them high priority then.

Regarding tables: My understanding is that Muse supports tables.el and org tables (plus a third style). The org reader should be able to read tables.el formatted tables as well (#3314). It seems to me that a simple way to do this would be to extract the grid table parser from the markdown reader into a separate module. Same for the org table parser. @jgm, would you be okay with a separate Table module, collecting all (shared) table parsers?

Text.Pandoc.Parsing already contains gridTableWith. Can you just use that? +++ Albert Krewinkel [May 01 17 07:43 ]:

Text.Pandoc.Parsing already contains gridTableWith. Can you just use that?

Ah, yes. I had missed that.

I generalized the signature of tableWith to

tableWith :: (Stream s m Char, HasReaderOptions st, Monad mf)
          => ParserT s st m (mf [Blocks], [Alignment], [Int])
          -> ([Int] -> ParserT s st m (mf [Blocks]))
          -> ParserT s st m sep
          -> ParserT s st m end
          -> ParserT s st m (mf Blocks)

i.e. the state is no longer fixed to ParserState and table-cell block parsers must return values wrapped in a monad. This requires a bit of Identity wrapping and unwrapping in the RST reader, but seems to work well.

[jgm]

Oh, good. I wonder if your generalization of gridTableWith would allow it to be used in the Markdown reader? Currently we don't use it there, mostly because of the F monad, if I recall. (But part of the reason is also that in Markdown grid tables we support alignments now. Actually, it should be fairly harmless to allow those in the RST reader, since an actual RST document wouldn't have alignment markings.)

[tarleb]

I pushed the changes and can take a look into merging the Markdown-specific gridTable parser into the generic parser.

Added tables support. It is aimed to be compatible with Emacs Muse, not Text::Amuse, as Text::Amuse differences are considered a bug: melmothx/text-amuse#14

For example, tables are not required to be indented with a space, although writer indents them now for compatibility with Text::Amuse #3649.

@jgm Tables and lists are now supported. I rebased against master and removed all hlint warnings. No definition lists and Org tables (A Muse Wiki does not support them either, though) yet.

[jgm]

Great, thanks!

[melmothx]

Text::Amuse does support definition lists https://amusewiki.org/library/manual#toc16 (documented since February 2016).

@melmothx "A Muse Wiki does not support them either, though" was related to Org tables only.
