I. BUILD
A qmake project file is provided. Compiling is just as easy as:
$ qmake && make
A default Makefile is provided in case qmake is not available.
By default YAS uses readline as its input backend. If readline is not
available it can be built with a simplified input backend. To disable
the readline backend you can either :
# comment out / remove the line "CONFIG += readline" from yas.prog
# remove "-DYAS_USE_READLINE" and "-lreadline -lncurses" from the
default Makefile
A full rebuild is needed for the configuration change to take effect :
$ make clean && qmake && make
or, if using the default Makefile :
$ make clean && make
II. USE
$ yas
The program then behaves like a standard shell.
Type "exit" to quit.
You can use "liste_ps" or "list_tasks" (same command) to get the statuses
of all the tasks running background.
III. DOCUMENTATION
The documentation is provided as doxygen (see ./doc/html/index.html).
You can regenerate it in case it has evolved or isn't present by doing :
$ doxygen
IV. POSSIBLE IMPROVEMENTS
# better error reporting (exec.c)
# completion of executables in $PATH
# management of user-defined variables
# management of special variables ($0..$n $? $0)
# complex redirections like >> 2>1 &>
# implementation of && and ||
# arithmetic expansion
# logic, control flow & functions
