A small module which automatically hotswaps changed Lua files in a running LÖVE project.
Lurker will automatically detect changed files and hotswap them into the running project.
To more easily make use of additional functionality, the lurker module can be set to a variable when it is required into the project:
lurker = require "lurker"
As opposed to using the
lurker.update() function -- such to avoid the
overhead of repeatedly polling for file changes -- you can instead opt to
trigger a scan of the directory by calling
lurker.scan() manually. If the
scan detects any changes a hotswap is performed.
lurker.preswap can be set to a function. This function is called before a
hotswap occurs and is passed the name of the file which will be swapped. If the
true then the hotswap is canceled.
lurker.preswap = function(f) print("File " .. f .. " swapping...") end
lurker.postswap can be set to a function. This function is called after a
hotswap occurs and is passed the name of the file which was swapped.
lurker.postswap = function(f) print("File " .. f .. " was swapped") end
Dictates whether lurker should run in protected mode; this is
default. If protected mode is disabled then LÖVE's usual error screen is used
when an error occurs in a LÖVE callback function; if it is enabled then
lurker's error state (which continues watching for file changes and can resume
execution) is used. Changes to this variable should be made before any calls to
lurker.update() are made.
Dictates what should happen if lurker tries to load a file which contains a
syntax error. If it is
false then lurker's error screen is shown until the
syntax error is fixed; if it is
true the error message is printed to the
console and the program continues. lurker.quiet is
false by default.
The interval in seconds for how often the scan of the directory is performed.
.5 by default.
The directory which is scanned for changes. This is
