Smalltalk ENVY

Nice - this blog post brings back some memories on ENVY - a Smalltalk source code management system. I used ENVY in the past too and still have a signed copy of the book "Mastering ENVY/Developer" in my bookshelf



And yes - after coding in VisualAge for Smalltalk I also used VisualAge for Java which was really a nice tool for that time - it lowered the Java pain. Because at that time most Java people coded in editors like Notepad while VisualAge for Java was a full IDE with Browser, Debugger and all. It was built on top of the Smalltalk version like most of the members of the VisualAge family

Tonel

Tonel is a file-per-class format for monticello repositories. It allows to store the class definition and methods in a single file. The idea is to use this for a more performant git support in Pharo (as currently a file per method is used). Code is in https://github.com/pharo-vcs/tonel

Updated Pharo Launcher

According to Peter the updated Pharo Launcher automatically downloads the proper VM. No more VM juggling.

First-class undefined classes for Pharo

Lets assume a class A requires a class B which is defined in a different package than class A.

If you defined the wrong load order of packages (so you load the package with A before the package with B) you might easily hit the problem of "Undefined classes".

Pharo will now address this issue better by having first class entities representing missing (or yet undefined) classes. It is already planned for Pharo 7.

Here are the slides from ESUG 2017 on this topic to give you more informations.
