This is the NOBDW version of Joy1. Joy is a decent language and needs a ditto presentation. The original version can be seen here.
Changes
Some changes were done that make the build environment me happy. One new
thing is a portable makefile, following this advice.
There is something different in these sources compared to the ones that can be
downloaded from the archived original and that is the
comments at the start of main.c and of interp.c.
Manfred von Thun really wanted those
comments in main.c, but the newsgroup did not allow attachments, so it was
never published as such.
As for the comments in interp.c, I added them because I like some version
history. It proves that the language and the implementation was not done over
night.
In fact, according to this interview
the implementation in C was started in 1995. And according to the
bibliography the first papers about
Joy date back to 1994.
Build instructions
rm -rf build
mkdir build
cd build
cmake -G "Unix Makefiles" ..
cmake --build .
cp ../lib/usrlib.joy ~
mkdir ~/usrlib
cp ../lib/* ~/usrlib
Then manually change the path to inilib.joy in ~/usrlib.joy from "../lib" to "usrlib".
Build with MSVC
cmake --build . --config Release
copy Release\joy.exe
copy ..\lib\usrlib.joy %HOMEPATH%
mkdir %HOMEPATH%\usrlib
copy ..\lib\*.* %HOMEPATH%\usrlib
Then manually change the path to inilib.joy in %HOMEPATH%\usrlib.joy from "../lib" to "usrlib".
Running
joy -h
gives an overview of available options.
Testing
cd ../test2
for i in *.joy
do
../build/joy $i >$i.out
done
grep -l false *.out
There are some false positives. The test files assume that usrlib.joy was loaded successfully.
