VectorGraphcis plugin

It does require background in building with C & Linux tools

Until the VectorEnginePlugin is merged into the OpenSmalltalk release, you can build it if you build a Squeak VM.

The basic steps are to [A] Generate the VectorEnginePlugin.c code using a Cuis specialized VMMaker package [B] Build an OpenSmalltalk VM,[C] Test the result, and [D] install in a typical place.

As I primarily use Linux on Arm64, I will describe the process for that platform.

[A] Generate VectorEnginePlugin.c

• On a fresh Cuis image, update to latest.
• Feature require: 'VectorEnginePlugin'.
• Open a Browser and find Class VectorEnginePlugin.
• Select the Class Comment text and execute it:

 VectorEnginePlugin
    translateInDirectory: DirectoryEntry currentDirectory
    doInlining: true

• You can now quit the image and should find file "VectorEnginePlugin.c

[B] Build an OpenSmalltalk VM

• Make a place (e.g. mkdir ~/OpenSmalltalk; cd ~/OpenSmalltalk)
• git clone --depth 1 https://OpenSmalltalk/opensmalltalk-vm oscogvm
• cd oscogvm/build.<yourplatform></yourplatform>/squeak.<vmkind></vmkind>.spur

cd oscogvm/build.linux64ARMv8/squeak.stack.spur

If not arm64, you can use "cog" in place of "stack"

Note: file HowToBuild

• mkdir ~/OpenSmalltalk/oscogvm/platforms/Cross/plugins/VectorEnginePlugin
• cp /VectorEngintPlugin.c ~/OpenSmalltalk/oscogvm/platforms/Cross/plugins/VectorEnginePlugin
• edit plugins.ext to add a new line at the end (after SHA2Plugin \) with the single line VectorEnginePlugin
• cd build
• ./mvm
• Answer "y" to the prompt "clean?"

This last should result in a message "Libraries have been installed in"

• cd to installed-in location, e.g.

~/OpenSmalltalk/oscogvm/products/sqstackspur64ARMv8linuxht/lib/squeak/5.0-*

• ls should show a "squeak" executable and support libs, e.g. VectorEnginePlugin.so
• Test _in this directory_

[Assume]

./squeak $CUIS/Cuis5.0-<whatever></whatever>.image

• In Cuis,

 Feature require: 'SVG'.
 VectorEngineWithPlugin isPluginAvailable. "Should answer true"
