Re: [Bug-apl] Emacs lib loaded automatically

[Juergen Sauermann]

Hi Elias,

my proposal would be this:

1. we give the --emacs command line option an argument. So apl would be started like:

    apl --emacs emacs_arg

2. the libemacs library provides a function emacs_start() with two char * arguments:

    void emacs_start(const char * emacs_arg, const char * lib_path);

This function would replace the function_mux(), get_signature(), and eval_XXX() functions.
lib_path is the absolute path to the libemacs library, which is normally /usr/lib/apl/libemacs.so
but can be different. GNU APL calls this function once on startup.

Regarding library locations, I believe we should avoid a situation where every package installs its own
library at their own place, leading to a scattered set of libraries. If a component needs additional libraries
then it should install them in a standard place like /usr/lib/apl or /usr/local/lib/apl as determined by ./configure.
I am also working on installing supporting workspaces (wslib3, 4, and 5) there.

Thanks!

Now, I need to be able to pass an initialisation argument, as well as a way to specify the location of the library. Any suggestion how to do this?

As for the init parameter, I'm now passing it into the native function (it's a single number that specifies the port number to listen to, or -1 to use Unix domain sockets).

Regards,

Elias
