> to learn a whole new set of tools The tools are how we find functionality that can be re-used and re-purposed to do what we need. A lot of exploring and reading existing stuff, less writing new stuff. > Smalltalk files are not plain text but rather images (or something) Mostly Smalltalk files are plain text files! There's a plain text log file with a replayable record of what you've been doing. There's a sources file with the source code. There are plain text file outs and change sets. There's the VM like the JVM — not a plain text file. There's the image, a cache of byte code (like Java .class files, Python .pyc files) and application state — not a plain text file. With a previous Pharo version: $ bin/pharo --headless Pharo10-SNAPSHOT-64bit-502addc.image hello.st pharo is the VM. Pharo10-SNAPSHOT-64bit-502addc.image is the image. hello.st is a plain text file. $ cat hello.st Stdio stdout nextPutAll: 'hello world'; nextPut: Character lf.! SmalltalkImage current snapshot: false andQuit: true!
