Getting hindent: Parse error: > when I run M-x hindent/reformat-decl on that function. Does Hindent not have Literate Haskell support?

I'll see if I can reproduce using TeX style

[mgsloan]

It doesn't, but it should be easy enough to add something to strip the > when editing a .lhs

TeX style should work fine, because hindent attempts to guess the boundaries of the declaration being edited, and only sends that to haskell-src-exts.

[chrisdone]

Indeed, TeX style should require no special support.

[gibiansky]

It sounds like this should probably be a feature added to the editor scripts, not hindent Haskell code itself, yeah?

[chrisdone]

I suppose either works. But if TeX style works just fine then we don't have to bother with bird-style. A bunch of tooling doesn't work with bird-style anyhoo.

[pharpend]

@gibiansky Well, no, because editors other than vim & emacs might want this functionality. In that case, they'll undoubtedly encounter this bug at some point. It seems like it should be fixed in HIndent so that everyone doesn't have to add their own patch.

[gibiansky]

This is supported now that #111 is merged.
