If named parameters are used, Mediawiki will <br /> automatically remove any leading or trailing whitespace from the parameter. <br /> Depending on the intended use, it may be advantageous to either preserve or<br /> remove such whitespace.<br /> <br /> Global options<br /> ignore_errors: If set to 'true' or 1, any error condition will result in <br /> an empty string being returned rather than an error message. <br /> <br /> error_category: If an error occurs, specifies the name of a category to <br /> include with the error message. The default category is <br /> [Category:Errors reported by Module String].<br /> <br /> no_category: If set to 'true' or 1, no category will be added if an error<br /> is generated.<br /> <br /> Unit tests for this module are available at Module:String/tests.<br /> ]]<br /> <br /> local p = {}<br /> <br /> --[[<br /> Helper function that populates the argument list given that user may need to use a mix of<br /> named and unnamed parameters. This is relevant because named parameters are not<br /> identical to unnamed parameters due to string trimming, and when dealing with strings<br /> we sometimes want to either preserve or remove that whitespace depending on the application.<br /> ]]<br /> function p.getParameters( frame_args, arg_list )<br /> local new_args = {};<br /> local index = 1;<br /> local value;<br /> <br /> for i,arg in ipairs( arg_list ) do<br /> value = frame_args[arg]<br /> if value == nil then<br /> value = frame_args[index];<br /> index = index + 1;<br /> end<br /> new_args[arg] = value;<br /> end<br /> <br /> return new_args;<br /> end <br /> <br /> --[[<br /> Helper Function to interpret boolean strings<br /> ]]<br /> function p.getBoolean( boolean_str )<br /> local boolean_value;<br /> <br /> if type( boolean_str ) == 'string' then<br /> boolean_str = boolean_str:lower();<br /> if boolean_str == 'false' or boolean_str == 'no' or boolean_str == '0' <br /> or boolean_str == '' then<br /> boolean_value = false;<br /> else<br /> boolean_value = true;<br /> end <br /> elseif type( boolean_str ) == 'boolean' then<br /> boolean_value = boolean_str;<br /> else<br /> error( 'No boolean value found' );<br /> end <br /> return boolean_value<br /> end<br /> <br /> function p.defined(frame)<br /> local arg = mw.text.trim(frame.args[1])<br /> --if arg == tostring(tonumber(arg)) then -- undesired result for '-0'<br /> -- arg = tonumber(arg)<br /> --end<br /> --if mw.ustring.find(arg, '^%s*-?[1-9][0-9]*%s*$') ~= nil or arg == '0' then<br /> -- arg = tonumber(arg)<br /> --end<br /> if mw.ustring.find(arg, '^-?[1-9][0-9]*$') ~= nil then<br /> arg = tonumber(arg)<br /> elseif arg == '0' then<br /> arg = 0<br /> end<br /> return frame:getParent().args[arg] ~= nil<br /> end<br /> <br /> return p</div>
