Developing on macOS

You can develop GRX programs on macOS.

Install

brew tap ev3dev/tools
brew install grx

Fonts

Since GRX3 only uses bitmap fonts, we need a way to find some. One way is to install XQuartz and then add a Fontconfig configuration file that points to the X11 fonts.

cat > /usr/local/etc/fonts/conf.d/00-x11.conf << EOF
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
        <dir>/opt/X11/share/fonts</dir>
</fontconfig>
EOF

Then run fc-cache to load the new fonts.

Run sample programs

These are not installed in $PATH, so you have to use the absolute path.

Example binary files are found in /usr/local/lib/grx-3.0/examples/. For example:

/usr/local/lib/grx-3.0/examples/vala/life

Example scripts (text files) are found in /usr/local/share/doc/grx/examples/. For example:

/usr/local/share/doc/grx/examples/python/life.py
