This allows Perl scripts to manipulate symbols in +a manner similar to the way in which logical names are manipulated via +the built-in C<%ENV> hash. Alternatively, one can call methods in this +package directly to read, create, and delete symbols. + +=head2 Tied hash interface + +This interface lets you treat the DCL symbol table as a Perl associative array, +in which the key of each element is the symbol name, and the value of the +element is that symbol's value. Case is not significant in the key string, as +DCL converts symbol names to uppercase, but it is significant in the value +string. All of the usual operations on associative arrays are supported. +Reading an element retrieves the current value of the symbol, assigning to it +defines a new symbol (or overwrites the old value of an existing symbol), and +deleting an element deletes the corresponding symbol. Setting an element to +C<undef>, or C<undef>ing it directly, sets the corresponding symbol to the null +string. You may also read the special keys ':GLOBAL' and ':LOCAL' to find out +whether a default symbol table has been specified for this hash (see C<table> +below), or set either or these keys to specify a default symbol table. + +When you call the C<tie> function to bind an associative array to this package, +you may specify as an optional argument the symbol table in which you wish to +create and delete symbols. If the argument is the string 'GLOBAL', then the +global symbol table is used; any other string causes the local symbol table to +be used. Note that this argument does not affect attempts to read symbols; if +a symbol with the specified name exists in the local symbol table, it is always +returned in preference to a symbol by the same name in the global symbol table. + +=head2 Object interface + +Although it's less convenient in some ways than the tied hash interface, you +can also call methods directly to manipulate individual symbols. In some +cases, this allows you finer control than using a tied hash aggregate. The +following methods are supported: + +=item new + +This creates a C<VMS::DCLsym> object which can be used as a handle for later +method calls. The single optional argument specifies the symbol table used +by default in future method calls, in the same way as the optional argument to +C<tie> described above. + +=item getsym + +If called in a scalar context, C<getsym> returns the value of the symbol whose +name is given as the argument to the call, or C<undef> if no such symbol +exists. Symbols in the local symbol table are always used in preference to +symbols in the global symbol table. If called in an array context, C<getsym> +returns a two-element list, whose first element is the value of the symbol, and +whose second element is the string 'GLOBAL' or 'LOCAL', indicating the table +from which the symbol's value was read. + +=item setsym + +The first two arguments taken by this method are the name of the symbol and the +value which should be assigned to it. The optional third argument is a string +specifying the symbol table to be used; 'GLOBAL' specifies the global symbol +table, and any other string specifies the local symbol table. If this argument +is omitted, the default symbol table for the object is used. C<setsym> returns +TRUE if successful, and FALSE otherwise. + +=item delsym + +This method deletes the symbol whose name is given as the first argument. The +optional second argument specifies the symbol table, as described above under +C<setsym>. It returns TRUE if the symbol was successfully deleted, and FALSE +if it was not. + +=item clearcache + +Because of the overhead associated with obtaining the list of defined symbols +for the tied hash iterator, it is only done once, and the list is reused for +subsequent iterations. Changes to symbols made through this package are +recorded, but in the rare event that someone changes the process' symbol table +from outside (as is possible using some software from the net), the iterator +will be out of sync with the symbol table. If you expect this to happen, you +can reset the cache by calling this method. In addition, if you pass a FALSE +value as the first argument, caching will be disabled. It can be reenabled +later by calling C<clearcache> again with a TRUE value as the first argument. +It returns TRUE or FALSE to indicate whether caching was previously enabled or +disabled, respectively. + +This method is a stopgap until we can incorporate code into this extension to +traverse the process' symbol table directly, so it may disappear in a future +version of this package. + +=head1 AUTHOR + +Charles Bailey bailey@genetics.upenn.edu + +=head1 VERSION + +1.01 08-Dec-1996 + +=head1 BUGS + +The list of symbols for the iterator is assembled by spawning off a +subprocess, which can be slow. Ideally, we should just traverse the +process' symbol table directly from C. + diff --git a/vms/ext/DCLsym/DCLsym.xs b/vms/ext/DCLsym/DCLsym.xs new file mode 100644 index 0000000000..3918eb11e5 --- /dev/null +++ b/vms/ext/DCLsym/DCLsym.xs @@ -0,0 +1,151 @@ +/* VMS::DCLsym - manipulate DCL symbols + * + * Version: 1.0 + * Author: Charles Bailey bailey@genetics.upenn.edu + * Revised: 17-Aug-1995 + * + * + * Revision History: + * + * 1.0 17-Aug-1995 Charles Bailey bailey@genetics.upenn.edu + * original production version + */ + +#include <descrip.h> +#include <lib$routines.h> +#include <libclidef.h> +#include <libdef.h> +#include <ssdef.h> +#include "EXTERN.h" +#include "perl.h" +#include "XSUB.h" + +MODULE = VMS::DCLsym PACKAGE = VMS::DCLsym + +void +_getsym(name) + SV * name + PPCODE: + { + struct dsc$descriptor_s namdsc = {0,DSC$K_DTYPE_T,DSC$K_CLASS_S,0}, + valdsc = {0,DSC$K_DTYPE_T,DSC$K_CLASS_D,0}; + STRLEN namlen; + int tbltype; + unsigned long int retsts; + SETERRNO(0,SS$_NORMAL); + if (!name) { + PUSHs(sv_newmortal()); + SETERRNO(EINVAL,LIB$_INVARG); + return; + } + namdsc.dsc$a_pointer = SvPV(name,namlen); + namdsc.dsc$w_length = (unsigned short int) namlen; + retsts = lib$get_symbol(&namdsc,&valdsc,0,&tbltype); + if (retsts & 1) { + PUSHs(sv_2mortal(newSVpv(valdsc.dsc$w_length ? + valdsc.dsc$a_pointer : "",valdsc.dsc$w_length))); + if (GIMME) { + EXTEND(sp,2); /* just in case we're at the end of the stack */ + if (tbltype == LIB$K_CLI_LOCAL_SYM) + PUSHs(sv_2mortal(newSVpv("LOCAL",5))); + else + PUSHs(sv_2mortal(newSVpv("GLOBAL",6))); + } + _ckvmssts(lib$sfree1_dd(&valdsc)); + } + else { + ST(0) = &sv_undef; /* error - we're returning undef, if anything */ + switch (retsts) { + case LIB$_NOSUCHSYM: + break; /* nobody home */; + case LIB$_INVSYMNAM: /* user errors; set errno return undef */ + case LIB$_INSCLIMEM: + case LIB$_NOCLI: + set_errno(EVMSERR); + set_vaxc_errno(retsts); + break; + default: /* bail out */ + { _ckvmssts(retsts); } + } + } + } + + +void +_setsym(name,val,typestr="LOCAL") + SV * name + SV * val + char * typestr + CODE: + { + struct dsc$descriptor_s namdsc = {0,DSC$K_DTYPE_T,DSC$K_CLASS_S,0}, + valdsc = {0,DSC$K_DTYPE_T,DSC$K_CLASS_S,0}; + STRLEN slen; + int type; + unsigned long int retsts; + SETERRNO(0,SS$_NORMAL); + if (!name || !val) { + SETERRNO(EINVAL,LIB$_INVARG); + XSRETURN_UNDEF; + } + namdsc.dsc$a_pointer = SvPV(name,slen); + namdsc.dsc$w_length = (unsigned short int) slen; + valdsc.dsc$a_pointer = SvPV(val,slen); + valdsc.dsc$w_length = (unsigned short int) slen; + type = strNE(typestr,"GLOBAL") ? + LIB$K_CLI_LOCAL_SYM : LIB$K_CLI_GLOBAL_SYM; + retsts = lib$set_symbol(&namdsc,&valdsc,&type); + if (retsts & 1) { XSRETURN_YES; } + else { + switch (retsts) { + case LIB$_AMBSYMDEF: /* user errors; set errno and return */ + case LIB$_INSCLIMEM: + case LIB$_INVSYMNAM: + case LIB$_NOCLI: + set_errno(EVMSERR); + set_vaxc_errno(retsts); + XSRETURN_NO; + break; /* NOTREACHED */ + default: /* bail out */ + { _ckvmssts(retsts); } + } + } + } + + +void +_delsym(name,typestr="LOCAL") + SV * name + char * typestr + CODE: + { + struct dsc$descriptor_s namdsc = {0,DSC$K_DTYPE_T,DSC$K_CLASS_S,0}; + STRLEN slen; + int type; + unsigned long int retsts; + SETERRNO(0,SS$_NORMAL); + if (!name || !typestr) { + SETERRNO(EINVAL,LIB$_INVARG); + XSRETURN_UNDEF; + } + namdsc.dsc$a_pointer = SvPV(name,slen); + namdsc.dsc$w_length = (unsigned short int) slen; + type = strNE(typestr,"GLOBAL") ? + LIB$K_CLI_LOCAL_SYM : LIB$K_CLI_GLOBAL_SYM; + retsts = lib$delete_symbol(&namdsc,&type); + if (retsts & 1) { XSRETURN_YES; } + else { + switch (retsts) { + case LIB$_INVSYMNAM: /* user errors; set errno and return */ + case LIB$_NOCLI: + case LIB$_NOSUCHSYM: + set_errno(EVMSERR); + set_vaxc_errno(retsts); + XSRETURN_NO; + break; /* NOTREACHED */ + default: /* bail out */ + { _ckvmssts(retsts); } + } + } + } + diff --git a/vms/ext/DCLsym/Makefile.PL b/vms/ext/DCLsym/Makefile.PL new file mode 100644 index 0000000000..8e6f5bce40 --- /dev/null +++ b/vms/ext/DCLsym/Makefile.PL @@ -0,0 +1,3 @@ +use ExtUtils::MakeMaker; + +WriteMakefile( 'VERSION_FROM' => 'DCLsym.pm' ); diff --git a/vms/ext/DCLsym/test.pl b/vms/ext/DCLsym/test.pl new file mode 100644 index 0000000000..57f2afbd20 --- /dev/null +++ b/vms/ext/DCLsym/test.pl @@ -0,0 +1,41 @@ +print "1..15\n"; + +require VMS::DCLsym or die "failed 1\n"; +print "ok 1\n"; + +tie %syms, VMS::DCLsym or die "failed 2\n"; +print "ok 2\n"; + +$name = 'FOO_'.time(); +$syms{$name} = 'Perl_test'; +print +($! ?
