I have found myself in a position where I must use Lua to walk a
directory tree and performing some operation on every file. Is there
an idiomatic way to do this in Lua?

Since standard C has no interface for dealing with directories, neither does core Lua. However, may people have written libraries which include file system manipulation, including directory iteration.

LuaFileSystem:
 -- http://www.keplerproject.org/luafilesystem/
 require "lfs"
 for name in lfs.dir"/foo" do
 print(name)
 end
lposix:
 -- http://www.tecgraf.puc-rio.br/~lhf/ftp/lua/#lposix
 require "lposix"
 for name in posix.files"/foo" do
 print(name)
 end
And there is also the "ex" API:
 -- http://lua-users.org/wiki/ExtensionProposal
 require "ex"
 for entry in os.dir"/foo" do
 print(entry.name)
 end
