Simple case

[jaccokrijnen]

I'm trying to use haskell-docs on a basic use case, but it won't work. Obviously I am missing something simple (I have enabled the documentation flag in my .cabal file).

➜  ~  cabal install tagsoup
Resolving dependencies...
Configuring tagsoup-0.13.3...
Building tagsoup-0.13.3...
Installed tagsoup-0.13.3
Updating documentation index /home/jacco/.cabal/share/doc/index.html
➜  ~  haskell-docs Text.HTML.TagSoup parseTags
Couldn't find any packages with that module.

Any hints?

(GHC 7.8.4/haddock 2.14.3/Ubuntu 14.04)

Just to check: are you doing that in a sandbox?

Though in any case, it seems that that incantation wouldn't give you any results:

$haskell-docs Text.HTML.TagSoup parseTags
$haskell-docs Text.HTML.TagSoup.Parser parseTags
Package: tagsoup-0.13.3
parseTags
Parse a string to a list of tags, using an HTML 5 compliant parser.
    parseTags "<hello>my&amp;</world>" == [TagOpen "hello" [],TagText "my&",TagClose "world"]

[jaccokrijnen]

Thanks. No, this is not in a sandbox (although I wonder, is there sandbox support?).

Trying that module gave me different output, though:

➜  ~  haskell-docs Text.HTML.TagSoup.Parser parseTags
➜  ~  

That is, no output at all.

By the way, Text.HTML.TagSoup re-exports parseTags, so shouldn't it be able to give documentation from there as well?

[ivan-m]

As a complete guess, as haskell-docs uses the Haddock files, and parseTags isn't listed as being defined in Text.HTML.TagSoup.Parser in the Haddock file (just like if you click on "source" it will take you to the source for .Parser).

[jaccokrijnen]

I do seem to get valid output for types and functions from the modules in base (GHC 7.8.4/haddock 2.14.3/Ubuntu 14.04)

[ivan-m]

Which version of GHC did you use to build tagsoup?

[jaccokrijnen]

Also 7.8.4

[ivan-m]

Did you rebuild haskell-docs since upgrading GHC? (It might need to be rebuilt against the new version of Haddock).

[jaccokrijnen]

Yes, I did. I also tried cabal installing from the repo, but still the same issue :(

[jaccokrijnen]

After some experimenting, I'm fairly certain that only documentation for the global package database is shown, and not for the user database. Could this be a haddock version issue?

Curious. Not sure.

I think I may have a similar issue. Sometimes the text package doesn't yield any results.
