-- For passed as named template parameter that is going to be preprocessed.
-- Since input text is assumed to has already been preprocessed, so '{', '}', and '<' are escaped
-- to prevent them to be preprocessed.  '[' is escaped to handle the case like '{{t1|a1=[[a}}
--
--    Example: frame:preprocess('{{t1|a1='..escapeNamedTemplateParameter(s)..'}}')
--
-- Note: This does not convert '=' to '{{=}}'
--
local function escapeNamedTemplateParameter(s)
	return s:gsub('[{}<[]', '%1<!---->'):gsub('|', '{{!}}')
end

-- Suitable for passed as unnamed template parameter that is going to be preprocessed,
-- as it also convert '=' to '{{=}}'
--
--    Example: frame:preprocess('{{t1|'..escapeTemplateParameter(s)..'}}')

	return s:gsub('[{}<[]', '%1<!---->'):gsub('[|=]', {['|']='{{!}}', ['=']='{{=}}'})
