ash_grant: Command for Claude Code

ExDoc Documentation Search

Search the local ExDoc documentation for accurate module and function information.

Usage

Invoke this command when you need to:

• Look up exact function signatures and typespecs
• Verify module documentation before writing README
• Understand existing API before modifying code
• Check if a function/module exists

Instructions

When this command is invoked with a search term (e.g., /docs Permission or /docs check evaluate):

1. Check if docs are fresh:

   • Compare doc/.build timestamp with latest lib/**/*.ex modification
   • If any source file is newer than docs, run mix docs first

2. Search the documentation:

   • Search doc/*.html files for the given term
   • Use grep to find relevant content
   • Extract module names, function signatures, and descriptions

3. Return structured results:

   • Module name and file path
   • Function signatures (def/defp)
   • @doc content
   • @spec if available
   • Related modules

Example Search Commands

# Check if docs need regeneration
DOC_BUILD="doc/.build"
LATEST_SOURCE=$(find lib -name "*.ex" -newer "$DOC_BUILD" 2>/dev/null | head -1)

if [ -n "$LATEST_SOURCE" ] || [ ! -f "$DOC_BUILD" ]; then
  echo "Docs outdated, regenerating..."
  mix docs
fi

# Search for the term
SEARCH_TERM="$ARGUMENTS"
grep -ril "$SEARCH_TERM" doc/*.html | while read file; do
  echo "=== $file ==="
  grep -i "$SEARCH_TERM" "$file" | sed 's/<[^>]*>//g' | head -20
done
