Not so great things It’s s t ill in early development • Things are changing fast • It lacks features • Documenta t ion • @e t iene_d FOSDEM 2016

How to get Sailor! $ luarocks install sailor 
 $ sailor create ‘My App’ /var/www 
 $ cd /var/www/my_app 
 $ lua start-server.lua @e t iene_d FOSDEM 2016

App structure /conf /controllers /models /pub /run t ime /tests /themes /views @e t iene_d FOSDEM 2016


 
 Example! -- /controllers/site.lua 
 local site = {} 
 function site.index(page) 
 local msg = “Hello World” 
 page:render(‘index’, { msg = msg } ) 
 end 
 function site.notindex(page) 
 page.theme = nil 
 page:write(“I’m different!”) 
 end 
 return site @e t iene_d FOSDEM 2016


 
 Example! <!-- /views/site/index.lp —> 
 <p> 
 A message from the server: 
 <?lua page:print(msg) ?> 
 <br/> 
 The message again: 
 <%= msg %> <!-- syntactic sugar: same thing as above —> 
 </p> 
 @e t iene_d FOSDEM 2016

@e t iene_d FOSDEM 2016


 Example! <?lua@server -- Code here runs on the server ?> 
 <?lua -- Same as above ?> 
 <?lua@client -- Runs at the client ?> 
 <?lua@both -- Runs at the server and the client ?> 
 <?lua@both 
 another_msg = “Another message” 
 ?> 
 <?lua page:print(another_msg) ?> 
 <?lua@client 
 window:alert(another_msg) 
 ?> @e t iene_d FOSDEM 2016
