Hello there,
I am currently using your library in my project eidolon, but when building it normally, I run into dependency hell. I averted it by removing the upper boundaries of the dependencies for yesod-core and yesod-form. Can you please consider relaxing your upper boundaries?
For now, it's time consuming to define custom extensions with markdownToHtml. For instance:
markdownToHtml :: Markdown -> Either PandocError Html
markdownToHtml md = do
let
readOp = yesodDefaultReaderOptions { readerExtensions = extensionsFromList yesodDefaultExtensions }
writeOp = yesodDefaultWriterOptions { writerExtensions = extensionsFromList yesodDefaultExtensions }
p <- parseMarkdown readOp md
writePandoc writeOp p
yesodDefaultExtensions :: [Extension]
yesodDefaultExtensions =
[ Ext_raw_html
, Ext_auto_identifiers
, Ext_pipe_tables
]How about creating markdownToHtmlWithExt :: [Extension] -> Markdown -> Either PandocError Html? With this function, we can choose which extensions to use and render markdown with them. The original markdownToHtml can be re-written as follows:
markdownToHtml :: Markdown -> Either PandocError Html
markdownToHtml = markdownToHtmlWithExt yesodDefaultExtensionsA missing Semigroup instance makes the version on hackage not build with GHC 8.4+. A new release would be nice. It may also be worthwhile to retroactively add an upper bound on base to the most recent hackage releases.
I assume that this is probably just an upper bounds bump.
Pandoc is back in nightly now, so we should be able to get our build going again.
ghc-7.8.x has new GND+role inference.
Here is new GND+role in detail.
It seems to be new GND+role inference causes compilation error.
Compilation log with ghc-7.8.2 is as follows:

Yesod/Markdown.hs:59:50:
Could not coerce from ‘m Text’ to ‘m Markdown’
because ‘m Text’ and ‘m Markdown’ are different types.
arising from the coercion of the method
‘persistent-1.3.0.6:Database.Persist.Sql.Class.sqlType’ from type
‘forall (m :: * -> *).
Monad m =>
m Text -> persistent-1.3.0.6:Database.Persist.Types.Base.SqlType’
to type
‘forall (m :: * -> *).

Possible fix:
use a standalone 'deriving instance' declaration,
so you can specify the instance context yourself

We often use the pipe markdown to create tables, but it's not in yesodDefaultExtensions. I suggest including it into yesodDefaultExtensions. What do you think about this?
Hi,
it would be easier for users and distro packages one can rely on what versions on hackage work together. Stackage solves this problem, and gives you free QA. Please consider joining stackage: http://www.stackage.org/authors
Greetings,

haddocks have been missing for a while
Hi,
I'll already save my markdown data on my DB (PostGreSQL).
now once i retrieve it, i want my markdown to converted first to HTML before to render in my hamlet.
hope you help me, thank you.
I need persistent 2.11 to get a bugfix for a persistent-template regression. At present yesod-markdown has persistent >= 0.9 && <2.11.
So, with Stackage LTS-5 and the pandoc update otherwise, it would be nice for yesod-markdown to support/allow pandoc 1.16. This is a breaking issue for those of us wanting to move to LTS-5 otherwise.
Incidentally, it would also be nice to get yesod-markdown into Stackage.

I have this package as build dependency in my project. Yesterday I switched to GHC 7.8.4 and cabal-1.22, Stackage LTS 2.1. Now, when I try to install yesod-markdown cabal tries install version 0.2.1, because of blaze-html < 0.8 constraint: LTS 2.1 Stackage snapshot have blaze-html ==0.8.0.2 constraint, thus cabal could pick version 0.2.1, since it is highest version which have no blaze-html dependency at all. All next versions are rejected. But this version is too old, and unsurprisingly fails to install:
Preprocessing library yesod-markdown-0.2.1...
Yesod/Markdown.hs:21:8:
Could not find module ‘Yesod.Form.Core’
Perhaps you meant
Yesod.Form.Types (needs flag -package yesod-form-1.4.4.1)
Yesod.Form.Nic (needs flag -package yesod-form-1.4.4.1)
Use -v to see a list of the files searched for.
Relaxing upper bound of blaze-html to < 0.9 makes package buildable, however I still can't install it, the error message is quite confusing to me:

It looks like the latest version of yesod-markdown (0.12.6.0) is missing haddocks on hackage.
It would be super helpful if you could upload these manually
