- Amber features an IDE with a Class browser, Workspace, Transcript, a ReferencesBrowser supporting senders/implementors and class references, basic Inspector and even a beginning of a Debugger and a unit TestRunner.
- Pharo Smalltalk is considered as the reference implementation.
- Amber is extendable with libraries, installable preferably via
amber-contrib-webwith a canvas to generate HTML, like Seaside, included in a new project by default,
silkwith a stream-like wrapping of DOM elements, included in a new project by default,
heliosIDE, included in a new project by default,
amber-contrib-legacywith smaller in-page "classic" IDE and some miscellany, included in a new project by default,
trysmalltalk, containing Prof Stef interactive crash course.
- and others. You can easily write an Amber library yourself.
For the installation to work, you need to have installed
node installers may install
npm as well.
git in Windows, use Git for Windows and select "Run Git from Windows Command Prompt" and "Checkout Windows-style, commit Unix-style" installation options.
For UNIX-based OS (Linux distibutions, FreeBSD, ...) do
npm config set prefix=~/npm export PATH="$PATH:$HOME/npm/bin"
to have the installation in a local subdirectory in order to avoid the otherwise necessary
sudo installation of Amber. The export line needs to be added to the ~/.profile file as well so that after a new login the path is set.
