In the perl distribution +directory, there will be (after make is run) a file called uperl.o, which +is all of perl except for a single undefined subroutine, named userinit(). +See usersub.c. + +The sole purpose of the userinit() routine is to call the initialization +routines for any modules that you want to link in. In this example, we just +call init_curses(), which sets up to link in the System V curses routines. +You'll find this in the file curses.c, which is the processed output of +curses.mus. (To get BSD curses, replace curses.mus with bsdcurses.mus.) + +The magicname() routine adds variable names into the symbol table. Along +with the name of the variable as Perl knows it, we pass a structure containing +an index identifying the variable, and the names of two C functions that +know how to set or evaluate a variable given the index of the variable. +Our example uses a macro to handle this conveniently. + +The init routine calls make_usub() to add user-defined subroutine names +into the symbol table. The arguments are + + make_usub(subname, subindex, subfunc, filename); + char *subname; + int subindex; + int subfunc(); + char *filename; + +The subname is the name that will be used in the Perl program. The subindex +will be passed to subfunc() when it is called to tell it which C function +is desired. subfunc() is a glue routine that translates the arguments +from Perl internal stack form to the form required by the routine in +question, calls the desired C function, and then translates any return +value back into the stack format. The glue routine used by curses just +has a large switch statement, each branch of which does the processing +for a particular C function. The subindex could, however, be used to look +up a function in a dynamically linked library. No example of this is +provided. + +As a help in producing the glue routine, a preprocessor called "mus" lets +you specify argument and return value types in a tabular format. An entry +such as: + + CASE int waddstr + I WINDOW* win + I char* str + END + +indicates that waddstr takes two input arguments, the first of which is a +pointer to a window, and the second of which is an ordinary C string. It +also indicates that an integer is returned. The mus program turns this into: + + case US_waddstr: + if (items != 2) + fatal("Usage: &waddstr($win, $str)"); + else { + int retval; + WINDOW* win = *(WINDOW**) str_get(st[1]); + char* str = (char*) str_get(st[2]); + + retval = waddstr(win, str); + str_numset(st[0], (double) retval); + } + return sp; + +It's also possible to have output parameters, indicated by O, and input/ouput +parameters indicated by IO. + +The mus program isn't perfect. You'll note that curses.mus has some +cases which are hand coded. They'll be passed straight through unmodified. +You can produce similar cases by analogy to what's in curses.c, as well +as similar routines in the doarg.c, dolist.c and doio.c routines of Perl. +The mus program is only intended to get you about 90% there. It's not clear, +for instance, how a given structure should be passed to Perl. But that +shouldn't bother you--if you've gotten this far, it's already obvious +that you are totally mad. + +Here's an example of how to return an array value: + + case US_appl_errlist: + if (!wantarray) { + str_numset(st[0], (double) appl_nerr); + return sp; + } + astore(stack, sp + appl_nerr, Nullstr); /* extend stack */ + st = stack->ary_array + sp; /* possibly realloced */ + for (i = 0; i < appl_nerr; i++) { + tmps = appl_errlist[i]; + st[i] = str_2mortal(str_make(tmps,strlen(tmps))); + } + return sp + appl_nerr - 1; + + +In addition, there is a program, man2mus, that will scan a man page for +function prototypes and attempt to construct a mus CASE entry for you. It has +to guess about input/output parameters, so you'll have to tidy up after it. +But it can save you a lot of time if the man pages for a library are +reasonably well formed. + +If you happen to have curses on your machine, you might try compiling +a copy of curseperl. The "pager" program in this directory is a rudimentary +start on writing a pager--don't believe the help message, which is stolen +from the less program. + +User-defined subroutines may not currently be called as a signal handler, +though a signal handler may itself call a user-defined subroutine. + +There are now glue routines to call back from C into Perl. In usersub.c +in this directory, you'll find callback() and callv(). The callback() +routine presumes that any arguments to pass to the Perl subroutine +have already been pushed onto the Perl stack. The callv() routine +is a wrapper that pushes an argv-style array of strings onto the +stack for you, and then calls callback(). Be sure to recheck your +stack pointer after returning from these routine, since the Perl code +may have reallocated it. diff --git a/gnu/usr.bin/perl/usub/curses.mus b/gnu/usr.bin/perl/usub/curses.mus new file mode 100644 index 000000000000..2c4d5d6013e3 --- /dev/null +++ b/gnu/usr.bin/perl/usub/curses.mus @@ -0,0 +1,808 @@ +/* $RCSfile: curses.mus,v $$Revision: 4.0.1.2 $$Date: 92/06/08 16:06:12 $ + * + * $Log: curses.mus,v $ + * Revision 4.0.1.2 92/06/08 16:06:12 lwall + * patch20: function key support added to curses.mus + * + * Revision 4.0.1.1 91/11/05 19:06:19 lwall + * patch11: usub/curses.mus now supports SysV curses + * + * Revision 4.0 91/03/20 01:56:13 lwall + * 4.0 baseline. + * + * Revision 3.0.1.1 90/08/09 04:05:21 lwall + * patch19: Initial revision + * + */ + +#include "EXTERN.h" +#include "perl.h" + +char *savestr();
