This Lua module can learn from a set of "raw" server traces and build a swagger spec with them.
It is intelligent enough to deduce common parameters from numbers or ids on the urls.
Copy the autoswagger folder inside your app. Then:
local autoswagger = require 'autoswagger' -- or 'autoswagger.init', depending on your package.path config
local brain = autoswagger.Brain:new()
brain:learn('GET', 'google.com', '/users/1/app/5')
brain:learn('GET', 'google.com', '/users/2/app/4')
brain:learn('GET', 'google.com', '/users/3/app/3')
brain:learn('GET', 'google.com', '/users/4/app/2')
brain:learn('GET', 'google.com', '/users/5/app/1')
brain:get_swagger('google.com') -- returns the swagger spec that the brain has learned from google.com. It probably includes /users/{user_id}/app/{app_id} as an operation.
This project uses busted for its specs. Just execute busted inside the root of the repo.
