What is a Mudlet package
It's a zip file that ends with .mpackage or .zip that contains xml files to import along with any resources a package might have (images, sounds and etc), or simply an .xml file on its own. Packages can be installed / uninstalled via a window in Mudlet.
You'll see packages represented in brown in the script editor everywhere - triggers, aliases, etc. All items of a package have to go into a package folder that they belong in - so the user can know which package do items belong to, and modify the package for their needs (if it didn't have a folder, then you wouldn't be able to 'add' anything to a package).
Where to find Mudlet packages
Check out the Scripts & Packages section on Mudlet forums for an excellent selection of Mudlet packages.
Some Mudlet packages may also be exlusively available on your own game-specific website or forums, so make sure to check out what your game has to offer as well.
What is a Mudlet module
It's the same thing as a Mudlet package - the only difference is how you import it: via the Module manager instead of the Package manager, and what happens after: Mudlet will save the module back to the original file instead of the profile save file. Really useful if you're writing Mudlet code to share with others - you won't have to ever manually export it again, Mudlet will do it automatically for you! You can version your modules using Git using this way.
You can also share a module across several profiles and automatically keep it in sync by installing the module in the relevant profiles and ticking the "sync" option in all of them.
How to install a Mudlet package
as a package
Drag and drop the package into Mudlet (as of 4.8+) and it'll get installed. The package will then get merged into the Mudlet profile and the original file can be deleted.
Alternatively, Toolbox→Package Manager will open the window where you can hit 'Install'.
as a module
Use Toolbox→Module Manager to install a module.
as a one-liner
As a script writer, you can also allow people to just copy/paste a command into Mudlet to install your package - super easy. Here's a demo, paste this into Mudlet:
lua function d(a,b)if not b:find("oci",1,true)then return end installPackage(b)os.remove(b)cecho("<lime_green>Package installed!\n")end registerAnonymousEventHandler("sysDownloadDone","d")downloadFile(getMudletHomeDir().."/oci.mpackage","http://www.mudlet.org/wp-content/files/one-click-install-demo.mpackage")
To get such a line for your script, do the following:
1) Copy/paste code below to https://mothereff.in/lua-minifier
local URL = "http://www.mudlet.org/wp-content/files/one-click-install-demo.mpackage" function d(_, f) if not f:find("oci", 1, true) then return end installPackage(f) os.remove(f) cecho("<lime_green>Package installed!\n") end registerAnonymousEventHandler("sysDownloadDone", "d") downloadFile(getMudletHomeDir()..(URL:ends("xml") and "/oci.xml" or "/oci.zip"), URL)
2) replace the URL (the
http://www.mudlet.org/wp-content/files/one-click-install-demo.mpackage bit) with your .zip, .mpackage, or .xml URL
3) find & replace all semicolons (;) with spaces ( ) in the minified version
4) prefix it with 'lua ' and paste it into Mudlet!
note: requires Mudlet 3.0 to work.

How to create a Mudlet package
Create a zip file that ends with either .mpackage (preferred) or .zip. Include all xml's that you'd like to be installed in the top level folder of the package (that is, don't have them within a folder in the archive - just have them be upfront).
Naming the package
Add a file at the top level of the package (so not inside any folders in the package) called config.lua that has the following line to name your package:
mpackage = "<name of your package>"
That's it. If you don't include config.lua, Mudlet will then deduce the package name from the file name.
Including images, sounds, and other files
If you'd like to include other folders or files in the package, you can - they will be copied into getMudletHomeDir().."/"..packagename upon installation, so your scripts can use them. Since Mudlet 3.10 you can include font files and they will be automatically available for your scripts to use.
For example, if your package is called "sipper" and you have health.png as an image in it, you can place on a label like so:
-- you don't have to worry about \ versus / for file paths - use / everywhere, Lua will make it work on Windows fine setBackgroundImage("my health label", getMudletHomeDir().."/sipper/health.png")
Install the one-liner package demo above for an example of how to make use of images in packages.
Using .lua files
As of Mudlet 3.6.2 you can
require "myfile" to load myfile.lua from the package folder.
As an example, if you have your package sipper, using a custom echo function named sipperecho defined in customFunctions.lua you can
require "sipper.customFunctions" sipperecho("I work")
Alternatively you can rename customFunctions.lua to init.lua, this will allow you to
require "<name of your package>" and
require "sipper" sipperecho("I work")
