A Minification Script for Squeak

Note: only tested on Linux and WSL.

Note: /!\ WIP: still contains some hardcoded paths you will have to adapt.

Installation

Dependencies:

"Install FileTree"
Metacello new
	baseline: 'FileTree';
	repository: 'github://dalehenrich/filetree:squeak4.3/repository';
	load.

"Install OSProcess"
Installer ss project: 'OSProcess'; install: 'OSProcess'.

Cleaner:

Clone and load via the Git Browser.
-OR-
Clone from the command line and load using FileTree:

repo := MCFileTreeRepository directory: (FileDirectory on: '/path/to/cloud-squeak/src').
repo allVersionNames do: [:name | (repo versionNamed: name) load].

Usage

Preparation (optional)

• Update the hardcoded file paths in REPLCleaner (Cmd + Shift + E on /...)

• Consider installing updates to the image.

• Install any additional packages you want to keep.

  After installation, edit REPLCleaner class>>#keepList to include the packages you want to keep.

• Change the start-up behavior at the bottom of REPLCleaner class>>#cleanupImage.

Run the cleaner

REPLCleaner
	wsl: false; "set to true if running on bare Windows when you want to use WSL. set to false if running on Linux or WSL."
	writeSpaceTally: false;
	save

This will produce an image called aws-final.image and open a telnet connection on port 8080, to which you can connect to via telnet localhost 8080.

Preen the image (optional, removes ~50MB of unused VM objects)

Open a VMMaker image and run the following:

SpurImagePreener new preenImage: '/path/to/aws-final.image'.

Know Issues

• If you do not connect to telnet within 60s, the image will start spamming "ConnectionTimedOut" errors. Probably due to some process we accidentally killed.

The telnet client for squeak is adapted from http://github.com/hpi-swa-teaching/squeak-repl and adjusted slightly to depend on fewer packages.

The message send recorder for creating detailed space tallies is adapted from https://github.com/hpi-swa/MessageSendRecorder.
