mod_http_errors: Add way to reuse the error page template
module:fire_event("http-message", {title = "hello"; message = "world"})
Goal is to enable consistent messages from Prosody. Not necessarily
error messages, but warnings or just notices.
This does cause some drift in the purpose of mod_http_errors, but that's
okay.
-- Compatibility layer for bitwise operations
-- First try the bit32 lib
-- Lua 5.3 has it with compat enabled
-- Lua 5.2 has it by default
if _G.bit32 then
return _G.bit32;
else
-- Lua 5.1 may have it as a standalone module that can be installed
local ok, bitop = pcall(require, "bit32")
if ok then
return bitop;
end
end
do
-- Lua 5.3 and 5.4 would be able to use native infix operators
local ok, bitop = pcall(require, "util.bit53")
if ok then
return bitop;
end
end
do
-- Lastly, try the LuaJIT bitop library
local ok, bitop = pcall(require, "bit")
if ok then
return bitop;
end
