This repository contains sources of the Pharo language. Pharo is a pure object-oriented programming language and a powerful environment, focused on simplicity and immediate feedback (think IDE and OS rolled into one).
To download the Pharo stable version for your platform, please visit:
This repository contains only sources of the Pharo image. The virtual machine source code is managed in a separate repository:
This repository is being built on a Jenkins server and uploaded to files.pharo.org.
The minimal image contains the basic Pharo packages without the graphical user interface. It is useful as a base for server-side applications deployment.
To bootstrap a new Pharo image you need the latest stable version of Pharo. For more information about bootstrapping, refer to guillep/PharoBootstrap.
The bootstrapping can be done on a properly-named branch using the following script:
BUILD_NUMBER=42 BOOTSTRAP_ARCH=64 bash ./bootstrap/scripts/bootstrap.sh
This will generate and archive images at various stages of the bootstrap process up to the full image in Pharo10.0-64bit-hhhhhhh.zip where hhhhhhh is the hash of the current checkout.
Additional information on the stages of the bootstrap and how to snapshot during the process are provided as comments in bootstrap.sh.
Tip: You can set BOOTSTRAP_REPOSITORY and BOOTSTRAP_CACHE environment variables to do the bootstrap outside of the source repository.
Tip: You can set BOOTSTRAP_VMTARGET to make the bootstrap use a virtual machine already present in your system (otherwise it will download it).
Note: If you are on a branch that doesn't follow the expected naming convention ('PharoX.Y'), then the script will pick an appropriate default (such as Pharo10.0). To build Pharo10.0 from a custom branch, you need to set BRANCH_NAME=Pharo10 before the bootstrap script is run.
You can also use docker if you prefer to control the bootstrapping environment completely. In the root directory of this project cloned from git, do
docker run --rm -it -v $(pwd)/:/src --workdir /src ubuntu:20.04 bash
In this container, you'll have to do some setup.
Bootstrapping requires the use of a 32-bit Smalltalk VM, hence we need 32-bit libraries
dpkg --add-architecture i386
apt update
You'll need these libraries/programs for the bootstrapping process
apt install -y build-essential git wget zip unzip libc6:i386 zlib1g:i386 libfreetype6:i386
This source code repository is exported in Tonel format. In this format, packages are represented as directories and each class is inside a single file.
Pharo is an opensource project very friendly to contributions of the users. See the document CONTRIBUTING how you can help to improve Pharo.
