Hoogle Search

Search Haskell APIs using Hoogle. You can search by:

• Function name: map, filter, foldl
• Type signature: a -> b -> a, (a -> Bool) -> [a] -> [a]
• Package-qualified: +base map, +containers lookup

Context

User query: $ARGUMENTS

Instructions

1. First, check if this is a search query or if the user needs help:

   • If the user asks for help, explain how Hoogle works
   • Otherwise, proceed with the search

2. Run the Hoogle search:

   ${CLAUDE_PLUGIN_ROOT}/scripts/hoogle-search.sh "$ARGUMENTS" --count 10
   

3. If the search fails with a database error:

   • Inform the user that the database needs to be initialized
   • Run ${CLAUDE_PLUGIN_ROOT}/scripts/hoogle-init-db.sh to generate it
   • This may take several minutes on first run

4. Present results clearly:

   • Show the function signature prominently
   • Include the module and package
   • Show relevant documentation
   • If the results seem off, suggest alternative search terms

5. For type signature searches, explain what the type means in plain language.

Output Format

For each relevant result, show:

• Function: functionName :: TypeSignature
• From: Module.Name (package-name)
• Description: Brief doc summary

If the user asks for details on a specific result, use --info to get full documentation.
