Wow, neat. Tell us how to use this!

Thanks!

There are some short instructions at the top of the lldb_webkit.py file:

    LLDB Support for WebKit Types

    Add the following to your ~/.lldbinit file to add WebKit Type summaries in LLDB and Xcode:

    command script import {Path to WebKit Root}/Tools/lldb/lldb_webkit.py

(You can also paste that command into into a running LLDB session.)

You'll need to restart Xcode after updating this file, but once you do, the Xcode variables view will allow you to inspect the contents of a HashTable, i.e. it will act as if the HashTable variable was an array of length var.m_tableSize.

Example from command-line lldb:

(lldb) p foo.m_impl
(WTF::HashSet<const char *, WTF::PtrHash<const char *>, WTF::HashTraits<const char> >::HashTableType) $0 = { tableSize = 64, keyCount = 3 } {
  (const char *) [0] = 0x0000000000000000
  (const char *) [1] = 0x0000000000000000
  (const char *) [2] = 0x0000000000000000
  (const char *) [3] = 0x0000000000000000
  (const char *) [4] = 0x0000000000000000
