Run failed with failed to parse: TODO deadEndsToString

[brandly]

hi! does the .elm file have valid syntax? it compiles? if so, could you share the file (or the whole project) with me?

i'm spitting out an error here when elm-syntax fails to parse an Elm file. maybe that repo has a bug.

elm-to-dot/src/Main.elm

Lines 105 to 106 in e098a6a

	Err e ->
	( model, Native.Log.line <| E.string ("failed to parse: " ++ Parser.deadEndsToString e) )

---

however, the TODO comes from the official elm/parser via Parser.deadEndsToString. the issue has been open since August 26, 2018.

pull requests have been submitted. @evancz even commented on one, while not actually addressing the PR. it's all very confusing.

i didn't realize this when i used that function. like why is the function even there if it's useless?

tl;dr - maybe your .elm is invalid or maybe elm-syntax has a bug. regardless, elm/parser needs attention.

fixed in v0.2.1. you should get something like this now:

$ elm-to-dot src/Main.elm
failed to parse: ExpectingEnd at row:18 col:5

run npm i -g elm-to-dot again to update!

@girishso thanks for letting me know about this!

if you think it's failing on valid Elm code, let me know! it's almost certainly a problem with elm-syntax, and i could help track it down or file the issue on that repo. thanks again.
