Playing with TruffleSqueak on Windows

This repository gathers Squeak code examples coming from various websites and books.
It also includes several batch files for experimenting with TruffleSqueak on a Windows machine.

This document is part of a series of topics related to TruffleSqueak on Windows:

Installing TruffleSqueak on Windows ▼
Building TruffleSqueak on Windows

Ada, Akka, C++, COBOL, Dart, Deno, Flix, Golang, GraalVM, Haskell, Kafka, Kotlin, LLVM, Node.js, Rust, Scala 3, Spark, Spring, WiX Toolset and Zig are other topics we are continuously monitoring.

Project dependencies

This project depends on the following external software for the Microsoft Windows platform:

Optionally one may also install the following software:

For instance our development environment looks as follows (July 2024) ²:

C:\opt\graalvm-ce-java11-22.3.0\³   (653 MB)
C:\opt\jdk-graalvm-ce-17.0.8_7.1\   (591 MB)
C:\opt\jdk-graalvm-ce-21_35.1\      (585 MB)
C:\opt\Git\                         (367 MB)
C:\opt\Squeak-6.0\                  (130 MB)

☛ Installation policy
When possible we install software from a Zip archive rather than via a Windows installer. In our case we defined C:\opt\ as the installation directory for optional software tools (in reference to the /opt/ directory on Unix).

Directory structure

This project is organized as follows:

docs\
examples\README.md
BUILD.md
README.md
RESOURCES.md
setenv.bat

where

directory docs\ contains TruffleSqueak related papers/articles.
directory examples\ contains Squeak code examples (see examples\README.md).
file BUILD.md is the Markdown document presenting the generation of the TruffleSqueak component.
file README.md is the Markdown document for this page. $ file [RESOURCES.md] is the Markdown document presenting external resources.
file setenv.bat is the batch script for setting up our environment.

We also define a virtual drive – e.g. drive T: – in our working environment in order to reduce/hide the real path of our project directory (see article "Windows command prompt limitation" from Microsoft Support).

🔎 We use the Windows external command subst to create virtual drives; for instance:
> subst T: %USERPROFILE%\workspace\trufflesqueak-examples

In the next section we give a brief description of the batch files present in this project.

Batch commands ▴

We distinguish different sets of batch commands:

setenv.bat - This batch command makes external tools such as java.exe and git.exe directly available from the command prompt (see section Project dependencies).

 > setenv help
 Usage: setenv { <option> | <subcommand> }
  
   Options:
     -debug      print commands executed by this script
     -travis     start Git bash shell instead of Windows command prompt
     -verbose    print progress messages
  
   Subcommands:
     help        print this help message

In the next section we present usage examples of the batch files present in this project.

Usage examples

`setenv.bat`

We execute command setenv once to setup our development environment; it makes external tools such as jar.exe and git.exe directly available from the command prompt:

> setenv
Tool versions:
   python 3.11.1, pylint 2.17.1, javac 11.0.18
   git 2.45.2, diff 3.10, bash 5.2.26(1)

> where git link
C:\opt\Git\bin\git.exe
C:\opt\Git\mingw64\bin\git.exe
C:\opt\Git\usr\bin\link.exe

Command setenv -verbose also displays the tool paths:

> setenv -verbose
Tool versions:
   python 3.11.1, pylint 2.17.1, javac 11.0.18
   git 2.45.2, diff 3.10, bash 5.2.26(1)
Tool paths:
   C:\opt\Python-3.11.1\python.exe
   C:\opt\Python-3.11.1\Scripts\pylint.exe
   C:\opt\graalvm-ce-java11-22.3.0\bin\javac.exe
   C:\opt\Git\bin\git.exe
   C:\opt\Git\mingw64\bin\git.exe
   C:\opt\Git\bin\bash.exe
Environment variables:
   "GIT_HOME=C:\opt\Git"
   "GRAALVM_HOME=C:\opt\graalvm-ce-java11-22.3.0"
   "JAVA_HOME=C:\opt\graalvm-ce-java11-22.3.0"
   "MSVC_HOME=C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC"
   "MSVS_HOME=C:\Program Files (x86)\Microsoft Visual Studio\2019"
   "PYTHON_HOME=C:\opt\Python-3.11.1"

`gu.bat install` (deprecated)

☛ Starting with version 20.0 command gu.cmd is part of the GraalVM distribution; Windows users should use gu.cmd instead of gu.bat.

Command gu.bat install -h displays the help message for command install.

> gu install -h
Usage: gu install [-0cdfhiLnoruv] {<param>}
Install specified components from file, URL or catalog.
 
  Options:
    -0, --dry-run        Dry run. Do not change any files.
    -c, --catalog        Treat parameters as component IDs from catalog. This is the default.
    -d, --debug          Show commands executed by this script.
    -f, --force          Disable installation checks.
    -h, --help           Display this help message.
    -i, --fail-existing  Fail if the to be installed component already exists.
    -L, --local-file     Treat parameters as local filenames of packaged components.
    -n, --no-progress    Do not display download progress.
    -o, --overwrite      Silently overwrite previously installed component.
    -r, --replace        Replace different files.
    -u, --url            Treat parameters as URLs
    -v, --verbose        Enable verbose output.

Command gu.bat install can add GraalVM installable components in three different ways, namely:

from a catalog (default, option -c)
from a local component archive (option -L)
from a remote component archive (option -u)

We present below the installation from a local TruffleSqueak component archive; further usage examples are available in document GU.md.

Let's first download TruffleSqueak component archive from the TruffleSqueak repository:

> curl -sL -o trufflesqueak-installable.jar https://github.com/hpi-swa/trufflesqueak/releases/download/22.3.0/trufflesqueak-installable-java8-windows-amd64-22.3.0.jar

Command gu.bat install -L trufflesqueak-component.jar adds the TruffleSqueak component to our GraalVM environment.

> echo %GRAALVM_HOME%
C:\opt\graalvm-ce-java11-22.3.0
 
> gu install -L trufflesqueak-installable.jar
Processing Component archive: trufflesqueak-installable-java11-windows-amd64-22.3.0.jar
Installing new component: TruffleSqueak (org.graalvm.smalltalk, version 22.3.0)

The GraalVM installation directory looks as follows after adding the TruffleSqueak component:

> where /r c:\opt\graalvm-ce-java11-22.3.0 *squeak*
c:\opt\graalvm-ce-java11-22.3.0\bin\trufflesqueak-launcher.cmd
c:\opt\graalvm-ce-java11-22.3.0\bin\trufflesqueak.cmd
c:\opt\graalvm-ce-java11-22.3.0\languages\smalltalk\trufflesqueak-shared.jar
c:\opt\graalvm-ce-java11-22.3.0\languages\smalltalk\trufflesqueak-shared.src.zip
c:\opt\graalvm-ce-java11-22.3.0\languages\smalltalk\trufflesqueak.jar
c:\opt\graalvm-ce-java11-22.3.0\languages\smalltalk\trufflesqueak.src.zip
c:\opt\graalvm-ce-java11-22.3.0\languages\smalltalk\bin\trufflesqueak-launcher.exe
c:\opt\graalvm-ce-java11-22.3.0\languages\smalltalk\bin\trufflesqueak.cmd
c:\opt\graalvm-ce-java11-22.3.0\lib\graalvm\trufflesqueak-launcher.jar
c:\opt\graalvm-ce-java11-22.3.0\lib\graalvm\trufflesqueak-launcher.src.zip

🔎 In the above output both command files bin\trufflesqueak.cmd and jre\bin\trufflesqueak.cmd simply forward the call to command file jre\languages\smalltalk\bin\trufflesqueak.cmd (on Unix systems two symbolic links are created instead).
> type c:\opt\graalvm-ce-java11-22.3.0\bin\trufflesqueak.cmd
@echo off
 
call :getScriptLocation location
set "GRAALVM_ARGUMENT_VECTOR_PROGRAM_NAME=%~0"
"%location%..\languages\smalltalk\bin\trufflesqueak.cmd" %*
exit /b %errorlevel%
 
:: If this script is in `%PATH%` and called quoted without a full path (e.g., `"js"`), `%~dp0` is expanded to `cwd`
:: rather than the path to the script.
:: This does not happen if `%~dp0` is accessed in a subroutine.
:getScriptLocation variableName
    set "%~1=%~dp0"
    exit /b 0
 
> type c:\opt\graalvm-ce-java11-22.3.0\jre\bin\trufflesqueak.cmd
@echo off
 
call :getScriptLocation location
"%location%..\languages\smalltalk\bin\trufflesqueak.cmd" %*
goto :eof
...
Command file jre\languages\smalltalk\bin\trufflesqueak.cmd itself is copied from template file template.trufflesqueak.cmd during the generation of the TruffleSqueak component.

Command trufflesqueak (with no argument) opens a dialog window for selecting a Squeak image before starting the Squeak IDE.

🔎 We have the choice between two Squeak images:

TruffleSqueak project : TruffleSqueakImage-<version>.image.

Squeak project : Squeak<version>-64bit.image.

Command trufflesqueak TruffleSqueak-22.3.0.image ⁴ starts the Squeak IDE and loads the provided Squeak image.

Code examples are presented in document examples\README.md.

Footnotes ▴

[1] Squeak image ↩

A Squeak image is required to run/test the TruffleSqueak installable component. Concretely we can either install the full Squeak distribution (32 MB) or we can just download the Squeak image (18 MB).

[2] Downloads ↩

In our case we downloaded the following installation files (see section 1):

trufflesqueak-installable-svm-java11-windows-amd64-22.3.0.jar  (  5 MB)
trufflesqueak-installable-svm-java17-windows-amd64-22.3.0.jar  (  5 MB)
graalvm-ce-java11-windows-amd64-22.3.0.zip          (154 MB)
graalvm-ce-java17-windows-amd64-22.3.0.zip          (154 MB)
PortableGit-2.45.2-64-bit.7z.exe                    ( 41 MB)
Squeak6.0-22104-64bit-202206021410-Windows-x64.zip  ( 33 MB)

[3] GraalVM and Java 8 ↩

Starting with version 21.3 GraalVM distributions are targeting Java 11 and Java 17; Java 8 users need to stay with GraalVM version 21.2.

[4] TruffleSqueak-22.3.0.image ↩
