Joy from Sympas translated to C.
Adding a new builtin, e.g. getch or putch, requires modification of the program in 4 locations: standardident{}, initialise(), standardident_NAMES[], and joy(). After translating from Pascal to C with the help of p2c some corrections were done. Reading the library files twice is not needed, given the nature of the language and that is why this feature was removed. After some more changes it is now transitioning from a small version of Joy to a full version of Joy.
rm -rf build
mkdir build
cd build
cmake -G "Unix Makefiles" ..
cmake --build .
cp joy.exe ..
Although this software contains almost no bugs, steps have been taken that make debugging easier. For a start, gdb requires that input comes from a file, so a typical session will be:
gdb joy
...
run tutorial.joy
...
quit
If the program crashes gdb sometimes answers to the command bt with: No stack.
In that case, LOGFILE or printf calls can be added to or in some functions.
